Rats lived 90% longer on C60 in olive oil

Professor Moussa, leader of the study team says in the interview that C60 (Buckminsterfullerene) is totally non-toxic. He has been researching Fullerene C60 for 18 years. Perhaps the most interesting part of the interview is that the research team killed the last surviving rat after 5.5 years because they were eager to conclude the experiment and publish its incredible results. So that rat did not die of natural causes and could have lived even longer. The Wistar rat used in the study normally lives only 2 to 3 years.

This site has articles on all aspects of this exciting new product. We found animal studies that documented brain rejuvenation in mice and the near-doubling of lifespan (PDF) and the prevention of cancer and the diseases of old age in rats. We also found toxicological studies that show that C60 (Buckminsterfullerene) in olive oil is safe. C60 in olive oil also has an extremely effective liver-protective effect, as documented in the same publication, where rats were poisoned to death with liver-destroying chemicals but the rats that took C60 barely were affected at all. Prof. Moussa mentions this in the interview:

“The rats that took C60 did not develop any tumors, unlike the rats in the control group.”

The scientific article this product is based on can be downloaded on the left sidebar of this site and in it you can see the autopsy results of the rat livers that were poisoned with a very toxic chemical. The rats that did not receive C60 beforehand quickly died and their livers look very pale and damaged. The C60-rats barely were affected and an autopsy showed healthy-looking livers.

Special-interest publications online have picked up on this major discovery in life extension science:

http://www.gizmag.com/diet-buckyballs-extending-lifespan/22245/

At the time of publication of the scientific publiction, many mainstream newspapers reported on this extraordinary breakthrough, however they all appeared to have pulled their articles because there is not a single trace to be found anywhere online anymore, not even using Google news. Zero search results for buckminsterfullerene lifespan in Google News, for example.

In addition to this strange scrubbing of news articles, there seems to be a concerted effort underway to spread disinformation on those articles that remain in the “really free press” (not owned by large multinational media conglomerates). Blatant disinformation is posted such as: “The longevity effect was mainly due to the olive oil, there was not much added benefit of the buckyballs” – blatantly untrue, since the C60-rats lived a full two years longer than the EVOO (extra virgin olive oil) control group. Note that the average rat only gets a couple of years old! There are also commenters who falsely claim that the extended lifespan was “theoretical only”, “based on extrapolation/estimation”. The opposite is the case: The rats were monitored until they died of natural causes. They lived 90% longer than rats on a normal diet. 5.5 years old, breaking the record for Wistar rats by an incredible margin. None of the rats died of the usual tumors or pneumonia – they all died of the generalized effects of old age. They aged twice as slow as normal and none of them died of any disease. Interestingly, the C60 preserved the extra virgin oilive oil very effectively: After six years, when the experiment had been concluded after all rats had died, the oil still had not turned rancid.

Conclusion: Carbon 60 in extra virgin olive oil is perhaps the most effective anti-aging and cancer-prevention agent imaginable. The brains of elderly mice rejuvenated to the level of young mice in a separate study. The C60-oil rats reached their maximum genetically determined lifespan (Hayflick limit). None of the rats died of the typical tumors they get in old age or, another common cause of death, pneumonia due to a weakened immune system. This news seems to be deliberately suppressed by the corporate media and there appears that there is an effort underway to discredit the published rat study and spread disinformation about its findings. A world where people don’t get cancer is a very scary world for Big Pharma.

Who is taking this and what do they report?

Since the news of the scientific experiment broke, a group of “early adopters” started to manufacture their own C60 in olive oil. Some invested in expensive equipment or had access to a lab and followed the original experiment to the letter, others cut corners. More than a thousand bottles have been sold by us in that phase as well. Initially, on Longecity.org was a huge thread with the experiences of those intrepid first-timers, but that thread has been removed, apparently because nearly everyone who took it reported immediate, long-lasting beneficial effects of the C60 in oil. The moderators then removed the thread, deleted the positive mentions of dozens of first-time-users and announced that they had split the thread into a scientific discussion on C60 only and a discussion on how to manufacture the product at home only, and that any mention of positive effects of C60 in extra virgin olive oil was explicitly forbidden and would be censored. You can verify this announced policy in these threads:

http://www.longecity.org/forum/topic/57492-c60-experiments-home/page__hl__mitophagy

http://www.longecity.org/forum/topic/57483-c60-in-olive-oil-mediated-life-extension-scientific-discussions/

The above threads are by far the most important threads discussing C60 online and the censorship is fortunately limited to the deletion of the mention of positive side effects.

Previously, on the deleted thread, the majority of experimenters reported these beneficial effects: More energy ... Less sleep needed ... “Mental inprovements” ... Can lift much heavier weights, sometimes to the point of causing tendon injury. Commonly reported... Can do more reps of the same weight. This was the most commonly reported benefit. People were adamant that there was a great difference, comparable to taking Creatine and that not even anabolic steroids enabled such an immediate increase of both repetitions and max. weight... Calmer, reduction in stress... Can run longer with seemingly more effective utilization of Oxygen. Less fatigue. “Cardiac improvements”. Better stamina and endurance... Can run faster whilst feeling more comfortable with a pulse that would normally be too high for steady-state... Higher libido. This is also seen in rat trials, already with 4 micrograms/kg, a dose five times lower than what we recommend as a daily dose.... Faster recovery of the skin after sunburn (with topical application).

Some of these reported effects may of course be due to the Placebo effect, on the other hand any longevity- or cancer-protective effects would not necessarily have to be accompanied by any noticeable physiological phenomena.

The current situation is:

- Mainstream media ignored the discovery or made a cursory mention that they later unceremoniously removed from their sites.

- Longevity and anti-aging forums had people taking this product but as soon as they started to report beneficial effects their posts were censored. To be honest, we do not think most people will notice (m)any noticeable effects when taking this product. We think that it may help prevent cancer and add some healthy years to a human’s life, but there is no way to be sure, and we will likely not find out this century. The results in higher mammals such as rodents are extremely encouraging however.

Brain Rejuvenation

Carboxyfullerene SOD mimetic improves cognition and extends the lifespan of mice

Kevin L. Quick, Sameh S. Ali, Robert Arch, Chengjie Xiong, David Wozniak, Laura L. Dugana

Abstract

In lower organisms, such as Caenorhabditis elegans and Drosophila, many genes identified as key regulators of aging are involved in either detoxification of reactive oxygen species or the cellular response to oxidatively-damaged macromolecules. Transgenic mice have been generated to study these genes in mammalian aging, but have not in general exhibited the expected lifespan extension or beneficial behavioral effects, possibly reflecting compensatory changes during development. We administered a small-molecule synthetic enzyme superoxide dismutase (SOD) mimetic to wild-type (i.e. non-transgenic, non-senescence accelerated) mice starting at middle age. Chronic treatment not only reduced age-associated oxidative stress and mitochondrial radical production, but significantly extended lifespan. Treated mice also exhibited improved performance on the Morris water maze learning and memory task. This is to our knowledge the first demonstration that an administered antioxidant with mitochondrial activity and nervous system penetration not only increases lifespan, but rescues age-related cognitive impairment in mammals. SOD mimetics with such characteristics may provide unique complements to genetic strategies to study the contribution of oxidative processes to nervous system aging.

The prolongation of the lifespan of rats by repeated oral administration of [60]
fullerene

Tarek Baati, Fanchon Bourasset , Najla Gharbi, Leila Njim, Manef Abderrabba, Abdelhamid Kerkeni, Henri Szwarc, Fathi Moussa

A b s t r a c t

Countless studies showed that [60]fullerene (C60) and derivatives could have many potential biomedical applications. However, while several independent research groups showed that C60 has no acute or subacute toxicity in various experimental models, more than 25 years after its discovery the in vivo fate and the chronic effects of this fullerene remain unknown. If the potential of C60 and derivatives in the
biomedical field have to be fulfilled these issues must be addressed. Here we show that oral administration of C60 dissolved in olive oil (0.8 mg/ml) at reiterated doses (1.7 mg/kg of body weight) to rats not only does not entail chronic toxicity but it almost doubles their lifespan. The effects of C60-olive oil solutions in an experimental model of CCl4 intoxication in rat strongly suggest that the effect on lifespan is mainly due to the attenuation of age-associated increases in oxidative stress. Pharmacokinetic studies show that dissolved C60 is absorbed by the gastro-intestinal tract and eliminated in a few tens of hours.

These results of importance in the fields of medicine and toxicology should open the way for the many possible -and waited for- biomedical applications of C60 including cancer therapy, neurodegenerative
disorders, and ageing.

AND METASTASIS

S.V. Prylutska1, A.P. Burlaka, Yu.I. Prylutskyy, U. Ritter, P. Scharff
Joint Ukrainian-German Center on Nanobiotechnology,

Aim: To estimate the impact of C60 fullerene aqueous solution (C60FAS) on the rate of transplanted malignant tumor growth and metastasis.

Methods: Lewis lung carcinoma was transplanted into ?57Bl/6J male mice. Conventional methods for the evaluation of antitumor and antimetastatic effects have been used. Results: The C60FAS at low single therapeutic dose of 5 mg/kg inhibited the growth of transplanted malignant tumor (antitumor effect) and metastasis (antimetastatic effect): the maximum therapeutic effect was found to be of 76.5% for
the tumor growth inhibition; the increase of animal life span by 22% was found; the metastasis inhibition index was estimated as 48%.

Conclusion: It was found that water-soluble pristine 60 fullerenes efficiently inhibit the transplanted malignant tumor growth and metastasis.

United Nuclear F60 / C60 Buckminsterfullerene scam

...Bob Lazar is a pathological liar also in mundane business matters, because he now claims another spectacular feat (again without offering the slightest evidence):

Mr. Lazar, in March 2012 when the rat study was published, traveled in a time machine to around 2007, so that he had the six years required to replicate that study, so that at the time of this writing, March 3, 2013, he could say: “Our partner lab recently completed a duplicate experiment involving 8 rats. We were able to produce superior results with very minor changes in the manufacturing process of the material.”

In order to replicate the study, he needed to have rats survive to at least 5.5 years of age. When he used rats that were 10 months old, and he produced “superior results”, he would have needed approx. 5 years to do the study. But how can he have spent that time, if the study itself was only published one year ago? And what are “superior results”? The rats lived even more than 90% longer, on average? Lazar is not going to publish the results of his “partner lab experiment”, even though it would establish him as a major authority in this field, since the entire world is waiting for a confirmation of its results. Lazar is not going to publish these results, and neither is the “partner lab” because he is lying – there are no such results because these has never been such a replicated study. This means that the very high price he asks for his “improved” “F60? is based on a lie. There is no improvement – it is a shameless lie.

On top of that, Mr. Lazar sternly warns only to buy C60 in olive oil from him, because others are out to scam you: “Beware of bogus companies and scam websites that claim to sell similar compounds and state that it authentic – but isn’t. We recently purchased some Fullerene-60 in olive oil from a very impressive website – only to find that there was no Fullerene-60 in it at all!”. Hmm.. We wonder what that very impressive website might be? There is a very, very modest website selling C60-in-oil in the US. It’s basically two spartan pages. And then there was Revgenetic’s website, but it hardly qualifies as impressive and they stopped selling C60 in oil after being exposed as yet-another-scammer (they used sonication to force-dissolve the C60 rapidly at high temperature, yielding a likely less effective product), having only sold it for a few weeks. But even though they took a very bad shortcut, their C60 itself was bona-fide. That leaves our site. We are indeed “impressive” – we have gathered close to all relevant info on this topic. We offer a wealth of sometimes hard-to-find scientific publications, all relevant toxicity studies, user comments, original research, manufacturing cost breakdown, allotropic dosing calculations, the works. So Bob Lazar implies that the C60 we sell is fake, all the while making a preposterously fraudulent statement about his “improved F60?, based on a “reproduced rat study with improved results”. Abject nonsense of course, since there are many ways to produce Buckyballs, but there is only one C60 molecule. All C60 molecules are absolutely identical on the quantum mechanical level! But Mr. Lazar in his infinite wisdom found a “better way with superior results” and used his connections in the UFO/Area 51 world to travel half a decade back in time, so as to have his “improved replicated experiment (of rats living at least 5.5 years..)” done in time to start selling now...

The prolongation of the lifespan of rats by repeated oral administration of [60]fullerene

A large-scale association study for nanoparticle C60 uncovers mechanisms of nanotoxicity disrupting the native conformations of DNA/RNA

Xue Xu, Xia Wang, Yan Li, Yonghua Wang, and Ling Yang

Abstract

Nano-scale particles have attracted a lot of attention for its potential use in medical studies, in particular for the diagnostic and therapeutic purposes. However, the toxicity and other side effects caused by the undesired interaction between nanoparticles and DNA/RNA are not clear. To address this problem, a model to evaluate the general rules governing how nanoparticles interact with DNA/RNA is demanded. Here by, use of an examination of 2254 native nucleotides with molecular dynamics simulation and thermodynamic analysis, we demonstrate how the DNA/RNA native structures are disrupted by the fullerene (C60) in a physiological condition. The nanoparticle was found to bind with the minor grooves of double-stranded DNA and trigger unwinding and disrupting of the DNA helix, which indicates C60 can potentially inhibit the DNA replication and induce potential side effects. In contrast to that of DNA, C60 only binds to the major grooves of RNA helix, which stabilizes the RNA structure or transforms the configuration from stretch to curl. This finding sheds new light on how C60 inhibits reverse transcription as HIV replicates. In addition, the binding of C60 stabilizes the structures of RNA riboswitch, indicating that C60 might regulate the gene expression. The binding energies of C60 with different genomic fragments varies in the range of -56 to -10 kcal mol-1, which further verifies the role of nanoparticle in DNA/RNA damage. Our findings reveal a general mode by which C60 causes DNA/RNA damage or other toxic effects at a systematic level, suggesting it should be cautious to handle these nanomaterials in various medical applications....

CONCLUSIONS

In this study, we have investigated the static and dynamic hybridization properties of C60 with DNA/RNA, and analyzed the potential toxic effects of the nanomolecule. Using statistical survey, MD simulations and thermodynamic analyses, we have found that:

In the C60–dsDNA hybrids, C60 prefers the minor grooves of dsDNA involving three consecutive GC base pairs (GC3), and the major grooves with three consecutive AT base pairs (AT3). The presence of the base pair AT in the binding sites plays a key role in determining the groove binding specificity of C60.

In the C60–dsRNA hybrids, C60 prefers the GC-rich regions of RNA, especially the GC-GC-AU sequences. More strikingly, the nanomolecule binds only to the major groove regions of RNA.

The difference between the initial identified sites and the final stabilized sites implies that C60 initially binds to the initial identified sites of DNA/RNA to induce the structural changes of the nucleotides, such as DNA/RNA twist, unwinding and curling. Then, the C60 molecule moves to the final stabilized sites, which probably leads to potential toxic effects. This is similar to the process of food intake by mouth (initial) and then digestion in stomach (final).

C60 hybridization enables to trigger the initiation of dsDNA unwinding, which probably inhibits the DNA discontinuous replication.

C60 enables to disrupt the structure of G-quadruplex DNA, and thereby provides a possibility to activate the telomerase by facilitating its access to telomeres and in this way promotes the proliferation of tumor cells.

C60 induces the conformational transition of HIV TAR RNA sequences from the stretch state to the curling state, which probably inhibits the HIV reverse transcription and represses the expression of HIV.

C60 binds to the substrate-binding site of riboswitch RNA, showing great potential to be a new type of riboswitch substrate to regulate the gene expression.

The nucleotides in the dsDNA stability, G-quadruplex disruption and stabilized riboswitch modes display much higher binding affinities to C60 than those in other modes, mainly due to the significant movement of C60, such as sliding.

[60]FULLERENE AND ITS USE TO MAINTAIN GOOD HEALTH AND TO PROLONG THE EXPECTED LIFESPAN OF MAMMALS

Inventor: MOUSSA FATHI &c

A water-insoluble fullerene is at least partially dissolved in a biocompatible lipid carrier, especially a fat or an oil such as butter, olive oil, and liquid paraffin. When administered to mammals, the fullerene, most preferably [60]fullerene dissolved in olive oil, scavenges free radicals and prolongs life span in rats.

BACKGROUND OF THE INVENTION

1. Field of the invention

The present invention concerns [60]fullerene and stable biocompatible compositions comprising [60]fullerene dissolved in a carrier. The present invention also relates to a method for increasing the expected lifespan (longevity) of a mammal, which comprises a step of administering [60]fullerene or a composition comprising a therapeutically effective amount of [60]fullerene. The present invention further concerns a method for preserving a mammal to damages caused by free radicals using said [60]fullerene or said composition.

2. Description of related art

Free radicals, such as oxygen radicals and other reactive oxygen/nitrogen/chlorine species (hydroxyl, nitric oxide radicals), are constantly formed in vivo. Some of these molecules are physiologically useful, but they can also result in pathological oxidative stress to cells and tissues. Endogenous defences include both antioxidants and repairing systems. However, excess production of free radicals, their production in inappropriate relative amounts or deficiencies in endogenous defences can have deleterious effects. Free radicals can cause oxidative damage to lipids, DNA, bio molecules, rises in the concentration of intracellular calcium, as well as activation of proteases, nucleases and protein kinases. Considerable evidence supports the view that oxidative damage involving free radicals occurs in most, if not all, human diseases. Oxidative stress is now recognized as an important contributor to the development of many human diseases including liver fibrosis, ischemia-reperfusion, atherosclerosis, neurodegenerative disease and age-related cancer as well as to process of ageing. Thus antioxidants and systems that can protect against oxidative stress are needed to maintain health. A large body of scientific evidence supports that oxidative stress is directly responsible for aging (Aging Cell. 2009, 8(3):258-69) and an array of neuropathology conditions (Nutrition 2010, 26:595-603. Neurochem Res. 2007, 32:757-73). The free radical theory of aging proposes that the organism is unable to repair all of them and that, with time, unrepaired damages accumulate and put the organism at risk: in other words, free radicals provoke aging and death (FEBS Letters 2009, 498: 183-186. J. Neurochem. 2009, 108:1251-65). Antioxidants are the substances able to react with free radicals and to protect the body from the damage caused by these molecules (Ital J Biochem. 2006, 55:263-282). In particular, consumption in excess of some foods which are rich sources of antioxidants is considered to promote good health and longevity. It is now believed that the maintenance of redox balance within the body can forestall aging and promote good health and longevity.

Due to its 30 carbon double bonds, [60]fullerene (Buckminsterfullerene, Ceo) is a powerful free radical scavenger which characterize it as a radical sponge (Science 1991, 254, 1 83- 1185). Biological applications of fullerenes and derivatives, in particular as antioxidants, have been extensively reviewed (Bioorg. Med. Chem. 1996, 4: 767- 779. Eur. J. Med. Chem. 2003, 38: 913-923. Biomedicine & Pharmacotherapy, 2005, 59: 351-358). Ceo is only soluble in a limited number of organic solvents, such as toluene, benzene, chloronaphtalene and dichlorobenzene. Availability of biocompatible aqueous solutions of Ceo and its derivatives that are insoluble in water have been major obstacles to toxicity and in vivo studies of this new family of compounds. Biological properties of water-insoluble fullerenes are still misunderstood and to our knowledge there are no certified toxicology data about them. Most of the fullerenes studied until now are water-soluble derivatives, since study of water-insoluble fullerenes, such as pristine Ceo, in biological medium proves difficult. It is a common practice to derivatize the fullerene core with substituants such as OH, COOH, NH2 to increase hydrophilicity (Bioorg. Med. Chem. 1996, 4: 767-779. Eur. J. Med. Chem. 2003, 38: 913-923. Biomedicine & Pharmacotherapy, 2005, 59: 351-358). Water-soluble Ceo derivatives have been found to retain in vitro the free radical scavenger properties of their parent fullerene molecule, allowing these properties to be exploited in biological systems. Many patents already exist for a broad range of biomedical applications and other commercial applications of water-soluble fullerenes, including anticancer and anti-HIV therapies, drugs for neurodegenerative diseases, drug delivery systems, and preparations that retard aging. In particular, a group of hydrophilic Ceo derivatives, carboxyfullerenes, were proposed to increase metazoan's lifespan (U.S. Patent Application 2003/0162837). However, water-soluble fullerenes are difficult to synthesize and to purify. Besides, in contrast to pristine Ceo, which is non-toxic, some C6o-derivatives can be highly toxic (Adv Exp Med Biol, 2007, 620, 168-80).

Pristine C6o has been shown to be more effective as an antioxidant than certain carboxyfullerenes in Wang, I. et al., J. Med. Chem. 1999, 42, 4614-4620. However, Ceo has not been employed as an active ingredient to develop an in vivo treating method in this publication. Aqueous suspensions of Ceo are well known in the art. They are stable for long periods and can be delivered to cells. A study of <14>C-labeled C-60 reported that it is possible to form suspensions of C6o in water that are stable for long periods (J. Am. Chem. Soc. 1994, 116, 4517-4518). However, the authors failed to detect the fullerene inside the cells and these suspensions containing very low concentrations of fullerene (typically 0.1 mg per ml) were inadequate to perform in vivo studies, especially toxicity studies. and metabolic fate investigations ((J. Am. Chem. Soc. 1994, 116, 4517-4518). Other vectorisation methods include the formation of inclusion complexes with cyclodextrins, calixarenes, tween-20, micelles, liposomes, and vesicles; however the Ceo concentrations reached by such methods are still very low (1 mg/mL at most) and inadequate to perform in vivo toxicity studies. Further, these methods present another drawback because they generally necessitate a preliminary dissolution step of the fullerene in an organic solvent. Other studies proposed the use of Ceo nanoparticles suspended in aqueous media to form a colloidal solution so-called nC60, however such solutions prpved to be highly toxic because they contain impurities linked to the oxidation byproducts of the solvents used during their preparation (Adv Exp Med Biol, 2007, 620, 168-80. Journal of Nanoscience Letters 2011 , 1 : 62-63). Another method, disclosed in J. Med. Chem. 2000, 43, 3186-3188 uses polyvinyl-pyrrolidone to solubilize C6o; however this vehicle can react with fullerene and the formed complex may cause harmful effects on mice embryos.

Moussa et al. described in Fullerene Science & Technology 1995, 3, 333-342 that partially micronized Ceo particles can be incorporated into living human phagocyte cells. C6o was directly suspended in the culture media and did not exhibit acute toxicity. Moussa et al. also described in Fullerene Science & Technology 1996, 4, 21-29 that micronized particles of water-insoluble fullerenes may be administered to mice on the form of a biocompatible aqueous suspension comprising a surfactant (tween 80) and a suspending agent (carboxym ethyl cellulose) which stabilizes the suspension. The authors disclosed that C6o is non-toxic, can cross cellular membranes and accumulates in liver and spleen (Fullerene Science & Technology 1996, 4: 21-29). The same group headed by F. Moussa have already used Micronized Ceo suspensions as free radical scavenger in vivo (Nano Letters 2005, 5: 2578 - 2585). However, the effective doses were very high (i.e. > 1 g/kg of body-weight) and intra peritoneal (i. p.) administration was the only route of administration for such suspensions. The authors also disclosed that Ceo can solubilize in vivo inside lipid droplets (Nano Letters 2005, 5: 2578 - 2585). This result has been confirmed in vitro by other authors whom studied [Omicron][beta][omicron] solubility in vegetable oils (Fullerenes, Nanotubes, and Carbon Nanostructures, 2007, 15: 311-314. Fullerenes, Nanotubes, and Carbon Nanostructures, 2007, 15: 331-339). Stable biocompatible compositions comprising water insoluble fullerenes dispersed and/or dissolved in a carrier selected from the group consisting of fats and oils in an amount ranging from 0.2 to 10 % by weight relative to the total weight of the composition, preferably from 0.1 to 2 % by weight, were already proposed by N Gharbi and F Moussa for preventing damages caused by free radicals (2005/lnternational Application No. PCT/EP2005/004963). However, in such compositions the water-insoluble fullerene is not fully dissolved and their oral absorption was unknown. Further, large aggregates of the administered fullerene can be filtered by liver and spleen and confined in their reticulo-endothelial system (RES) thus altering the diffusion and biodistribution of Ceo in the whole body. Thus, the in vivo use of water-insoluble fullerenes as free radical scavengers through delivery thanks to a non-aqueous carrier is still not satisfactory.

The inventors of the instant invention have now discovered a surprising use of [60]fullerene as agent that promotes an increases in the overall length of the expected lifespan of mammals.

Compositions comprising [60]fullerene and their use for preventing damages caused to metazons by free radicals are disclosed in TN Patent No.TN 2011/327 issued June 30, 2011 to Moussa et al. which is incorporated herein by reference in its entirety.

SUM MARY OF THE INVENTION

It is in view of the above problems that the present invention was developed. The main objective of the invention is to provide a process or method for extending the longevity of a mammal, which comprises a step of administering to said mammal a composition comprising an effective amount of [60]fullerene, which avoids the drawbacks of the prior art processes, and in particular : 1- avoids the use of charge transfer complexes, 2-avoids the use of organic solvents, and 3- avoids in situ aggregation of the administered fullerene. It has now been discovered by the inventors that the compositions comprising [60]fullerene dissolved in a suitable carrier selected from the group consisting of oils and fats proved suitable to achieve the aforementioned objectives. In particular, not only they allow [60]fullerene to be administered orally or intramuscularly or intra peritoneally to prolong the longevity of mammals but they are at least several times more active than previous compositions. Thus, a first embodiment of the instant invention comprises a stable biocompatible composition comprising (a) a carrier selected from the group consisting of fats and oils; and (b) [60]fullerene, wherein [60]fullerene is almost dissolved in said carrier. The embodiment is further drawn to compositions, in which [60]fullerene is dissolved in the carrier. Another embodiment of the instant invention is a method to prolong the longevity of mammals, which comprises a step of administering to said mammal a stable biocompatible composition comprising an effective amount of [60]fullerene dissolved in a carrier selected from the group consisting of fats and oils. In a preferred embodiment, the invention is drawn to a method of prolonging the longevity of mammals, which comprises a step of adding to food or any nutritional composition a stable composition comprising an effective amount of [60]fullerene dispersed in a carrier selected from the group consisting of fats and oils.

DETAILED DESCRIPTION OF THE INVENTION AND PREFERRED EMBODIMENTS

Free radicals are constantly formed in vivo. Some of these molecules are physiologically useful, but they can also result in pathological oxidative stress to cells and tissues. Endogenous defences include both antioxidants and repairing systems. However, excess production of free radicals, their production in inappropriate relative amounts or deficiencies in endogenous defences can have deleterious effects. Free radicals can cause oxidative damage to lipids, DNA, bio molecules, rises in the concentration of intracellular calcium, as well as activation of proteases, nucleases and protein kinases. Considerable evidence supports the view that oxidative damage involving free radicals occurs in most, if not all, human diseases. Oxidative stress is now recognized as an important contributor to the development of many human diseases including liver fibrosis, ischemia-reperfusion, atherosclerosis, several neurological disorders and age-related cancer as well as to process of ageing. Thus antioxidants and systems that can protect against oxidative stress are needed to maintain health and prolong the expected lifespan in metazoans. This has led to attempts to develop additional antioxidants to supplement the antioxidant defences of cells as potential therapeutic agents. Diet-derived antioxidants and a number of small molecules that can scavenge free radicals as well as super oxide dismutase-mimetics and chelators of transition metal ions were proposed as potential therapeutic agents against oxidative stress. Compositions according to the invention comprising [60]fullerene have been found to exhibit highly efficient antioxidant properties in vivo. The fullerene core, i.e. the fullerene skeleton without lateral substituants, used in the practice of this invention comprise clustered carbon structures generally spherical in shape and having a carbon content of 60 carbon atoms. Typically, [60]fullerene according to the invention is present in an amount ranging from 0.01 to 0.0.08 % by weight relative to the total weight of the composition, preferably 0.08 % by weight. [60]fullerene is preferably dissolved in the carrier, i.e. the composition can be filtered through a 0.2 pm filter. The stable, biocompatible compositions according to the invention comprise a carrier selected from the group consisting of fats and oils; and [60]fullerene, wherein said fullerene is mostly dissolved in said carrier. The carrier used in the present invention is a pharmaceutically acceptable and biocompatible carrier, selected from the group consisting of fats and oils.

Preferred carriers according to the invention are butter, cocoa butter, peanut butter, olive oil, soybean oil, cod-liver oil and liquid paraffin. As defined above, carriers may be used each alone or in a combination of two or more species. [60]fullerene is dissolved in the carrier, depending on the nature of the carrier. Some carriers are able to dissolve substantial amounts of water- insoluble fullerenes (several mg / g of carrier). In one embodiment, at least 0.8 mg of fullerene is dissolved per ml of the carrier (the carrier being a liquid). As an example, it is possible to dissolve a total weight up to 1 mg of C60 per g of olive or soybean oil in less than one week. The compositions according to the invention may be pharmaceutical compositions comprising the fullerene in a therapeutically effective amount. Preferably, said fullerene can protect against biologically reactive radical species, which means chemicals that are free radicals or contribute to the generation of free radicals. Generally, the biologically reactive radical species are generated from O2 or H2O2. Thus, the invention also concerns a method to prolong the longevity of a mammal, which comprises a step of administering to said mammal a stable biocompatible composition as defined hereinabove. [60]fullerene, when dissolved in the carriers of the present invention, can be administered to mammals and this compound is well absorbed by said mammals. Generally, the said fullerene is administered in an amount of at least 0.1 mg/kg of body weight per day. According to the method of the invention, the inventive compositions may be administered orally, intramuscularly, subcutaneously, intra dermally or intra peritoneally, rectally by suppositories or sublingually. For oral ingestion by a mammal to be treated, the carrier is preferably an edible carrier. In at least one embodiment, said composition is administered in a pure form. In another embodiment, it is administered in the form of an emulsion in water. In another embodiment the fullerene is administered as a labile C6o-derivative derivative that can deliver Ceo after administration. The compositions of the instant invention can be in any liquid or solid conventional pharmaceutical formulation. The carrier enables the fullerene to be formulated as tablets, pills, dragees, capsules, liposome, pomade, ointment, cream , lotion, emulsions, gels, syrups, slurries and the like. The compositions of the present invention are preferably presented for oral administration to mammals in unit dosage forms, such as tablets, capsules, and oral solutions, containing suitable quantities of [60]fullerene. The compositions may be sterilized and/or may contain some adjuvants such as preservatives, stabilizers, acidity regulators, natural or synthetic flavour, anti-foaming agents, viscosity- control agents, emulsifiers, salts for varying the osmotic pressure and/or other buffers. In addition, compositions may contain other pharmaceutically active agents. The level of free radicals and reactive oxygen species in mammal cells decreases following treatment as compared to the level of reactive oxygen species in a cell that has not been contacted with a composition according to the invention. Indeed, [60]fullerene according to the invention can act as antioxidant and supplement the antioxidant defences of cells. That means they inhibit oxidation or inhibit reactions promoted by reactive oxygen species. Physiologically relevant reactive oxygen species, which contribute to the generation of free radicals, include hydrogen peroxide, super oxide anion, and the like. The protective method of the invention reduces cell damage and death, and thus generally maintains the health of treated mammals. Further, the inventors discovered that [60]fullerene administered as biocompatible composition as described herein -1) can be absorbed after oral administration (Figure 2); -2) they can react inside the liver with vitamin A (retinol) and esters thereof following a Diels-Alder-like reaction without any toxic effect (New J Chem, 1998, 989-992) ; -3) they are eliminated through the bile ducts (Nano Letters 2005, 5 (12): 2578 - 2585); and -4) despite the large amounts administered, no acute or sub-acute toxicity could be observed in mice and rats. No behaviour or growth disorder could be observed in treated animals either, which can be seen on figure 1. The latter shows growth rate of three groups (n = 6) of rats which received weekly per os 1 ml of olive oil containing 0.8 mg of Ceo or 1 ml of olive oil only or 1 ml of water only. The in vivo new properties of [60]fullerene are due to fullerenes themselves and/or to the fullerene-retinol and fullerene-retinyl ester adducts formed after administration inside the liver. Also disclosed herein is a method for preparing a composition according to the present invention, comprising a carrier and particles of [60]fullerene. Said method comprises the steps of: - (a) Charging a milling vessel with the fullerene, the carrier and balls, said milling vessel and balls being made out of any biocompatible metal or polymer; - (b) Agitating the mixture resulting from step (a) until a homogeneous dissolution is obtained; and - (c) Sterilizing the composition resulting from step (b) by filtration. Direct mechanical milling in the carrier presents the advantages to accelerate the dissolution. Said method comprises the steps of: - (a) Charging a milling vessel with the fullerene, the fat or oil and balls, said milling vessel and balls being made out of any biocompatible metal or polymer; - (b) Agitating the mixture resulting from step (a) until complete homogenization of the solution; - (c) Agitating .the composition resulting from step (b) until complete dissolution of the fullerene; and - (d) Sterilizing by filtration the composition resulting from step (c). Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term "about." Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following specification and attached claims are approximations that may vary depending upon the desired properties sought to be obtained by the present disclosure. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should be construed in light of the number of significant digits and ordinary rounding approaches. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the disclosure are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements. The invention is further illustrated by the examples described below. These examples are meant to illustrate the i nvention and are not to be interpreted as limiting the scope of the invention.

EXAMPLES

General considerations

C60 (Purity: 99.98 %) was purchased from Term USA (Fort Bragg, CA, USA). Its characterization and its purity were assessed by HPLC, UV, C-NMR, and Mass Spectrometry. No impurity could be observed. It was used without further purification as well as after sublimation. All the other reagents were analytical grade and were purchased from Sigma (St Louis, MO). Animals received human care and the study protocols complied with general guidelines for the care and use of laboratory animals. Male Wistar rats (Charles River, France) were housed by groups of 3 in polypropylene cages at constant temperature (22 [deg.]C) and humidity (60 %) and with a 12 h light/dark cycle, and fed a standard diet ad libitum. All rats were allowed to acclimate to this facility for at least one week before being used in the experiments. At the end of the experiment, body weights were determined and the animals were sacrificed under the same conditions by bleeding through the thoracic aorta after sodium pentobarbital (1.0 mL/kg of body weight) anaesthesia.

Biochemical tests, Cso determinations and statistics were processed as previously described in Nano Letters 2005, 5 (12): 2578 - 2585.

Example 1 : Direct dissolution of [60]fullerene in a vegetable oil

In the stainless steel milling vessels of a Pulverisette 7 (Fritsch, Idar- Oberstein, Germany) or a similar device, add 8 mg of [60]fullerene and 10 mL of olive oil or 10 g of butter and 6 stainless steel balls (8 mm of diameter) (the milling vessels and the balls can be made out of any biocompatible metal or polymer such as stainless steel, tempered chrome steel, silicon nitride, corundum, tungsten carbide, agate, oxide of zirconium etc). Agitate the mixture during several hours (at 600 rpm for instance) until complete dissolution. The resulting homogenous solution or paste is then ready for use for oral administration or by any route of administration after appropriate sterilization. Sterilization may be achieved by filtration under vacuum (pore size: 0.2 [mu][eta][iota]). The sterilized composition is stable for at least 1 month. It is also possible to dissolve water- insoluble fullerenes in natural or mineral oils without stirring however the dissolution may be time consuming (up to several days at room temperature). Therefore, the former protocol is preferred. The fullerene concentration in compositions according to the invention can be determined by HPLC after adequate dilution in mobile phase as described previously (J. Chromatogr. B 1997, 696: 153-159).

Example 2: Pharmacokinetics and biodistribution of an oily solution after oral and intra-peritoneal administration in rats.

Pharmacokinetic studies were carried out with male Wistar rats (weighing 200 - 220 g). Rats were housed in individual cages and maintained in an air-conditioned room (22-25 [deg.]C) on a 12 h light/dark cycle with water and food available. The rats were acclimated for 7 days and they were fasted overnight but with access to water, before treatment.

Under general anesthesia, a catheter was introduced into the rat right jugular vein, positioned subcutaneously with the tip in the inter-scapular region. The prepared rats were then allowed to recover for 24 h, and the blood catheters were flushed with 0.9 % NaCI solution containing 20 l U/ml of heparin to avoid possible clot obstruction. Before Ceo administration, the rats were fasted overnight but with access to water. The same single dose of Ceo (4 mg/kg) was delivered orally, by a gavages needle, or intra-peritoneally to two groups of three rats. Blood (0.20 ml) was withdrawn via the canular prior to dosing (f = 0) and at 15, 30, 60 min and then at 2, 4, 8, 10, 12, 24 and 48 h post-dosing. Antithrombin heparin (20 lU/ml) was added in each blood sample. After each blood collection 0.20 ml of sterile 0.9 % NaCI solution were injected to the animal, to avoid hypovolemia. The rats were sacrificed 48 h after eo administration for organ collection (livers, spleens, and brains).

It was now discovered by the inventors that: -1) Soluble Ceo is absorbed and eliminated after either intraperitoneal or oral administrations. Table 1 represents the main pharmacokinetic parameters; 2- the maximal concentrations (Cmax) are reached 4 and 8 hours after i.p. and oral administrations, respectively (Fig. 2); 3- the maximal concentration after i.p. administration (1.47 +- 0.15 pg/ml) is higher than that after oral administration (0.52 +- 0.16 Mg/ml). Consequently, the area under the curve (AUC) is about 5 times larger when Ceo is administered by i.p. route as compared to oral route. Although these results do not allow determining the bioavailability of Ceo, they clearly show that a non-negligible % of the orally administered dose is absorbed as compared to the i.p. administered one (Fig. 2); and -3) the fullerene is well distributed in the whole body, in particular it can cross the brain barrier (table 2).

Example 3: Ceo-induced protection of the liver against acute toxicity of carbon tetrachloride (CCU) in rats

Carbon tetrachloride is a classical hepatotoxicant that causes rapid liver damage progressing from steatosis to centrilobular necrosis. CCU intoxication in rodents is an important model for elucidation of the mechanism of action of hepatotoxic effects such as fatty degeneration, fibrosis, hepatocellular death, and carcinogenicity. These effects are consistent with the known induced metabolic activation of CCI4 to reactive intermediates, including CCI3" and CCI02' free radicals, and mobilization of intracellular calcium. Kupffer cells (liver resident macrophages) participate in the mechanism of toxicity of CCI4 in vivo by release of chemoattractants for neutrophils and a series of chemical mediators (cytokines). Both expression and synthesis of these cytokines are mainly modulated through redox-sensitive reactions. Further, involvement of reactive oxygen species and lipid peroxydation products can be demonstrated in other fundamental events of hepatic fibrogenosis, like activation of hepatic stellate cells (HSC: liver resident nonparenchymal cells also referred to as fat-storing or perisinusoidal cells, lipocytes and Ito cells). In a previous work, the effects of C60-pretreatments on acute carbon tetrachloride intoxication in rats, a classical model for studying free-radical-mediated liver injury was reported. The results obtained by the authors leaded by F Moussa (Nano Letters 2005, 5 (12), 2578 - 2585) showed that aqueous C6o suspensions not only have no acute or subacute toxicity in rodents but they also protect their livers in a dose-dependent manner against free-radical damage. The most effective dose of C6o reported in the latter paper was about 2.5 g/kg of body-weight and was administered intra-peritoneally and the better protection was obtained at day 14 after administration. It was now discovered by the inventors that the fullerene is about 100 times more active it is administered in solution than in suspension, and the effect is more rapid (24 hours after administration) as compared to the results published previously in the same experimental model (Nano Letters 2005, 5: 2578 - 2585).

Example 4: Ceo prolongs the longevity in rats without chronic toxicity

The rats were housed one per cage and acclimated for 14 days, before dosing. Three groups of 10 rats ( 10 months old, weighing 495 +- 31 g) were administered daily for one week, then weekly until the end of the second month and then every two weeks until the end of the 7th month, by gavages with 1 ml of water or olive oil or Ceo dissolved in olive oil (0.8 mg/ml), respectively. The rats were weighed before each dosing. Routine observations following official recommendations (EC Commission Directive 2004/73/EC of 29 April 2004 Adapting to Technical Progress for the Twenty-Ninth Time Council Directive 67/548/EEC on the Approximation of the Laws, Regulations and Administrative Provisions Relating to the Classification, Packaging and Labeling of Dangerous Substances. O.J. No. L1522004) were made on all animals inside and outside the cage once a day throughout the study for signs of departure from normal activity, morbidity and mortality.

This experiment was initiated after observing that Ceo is absorbed through oral administration. To study the chronic toxicity of Ceo we designed a protocol according to the general guidelines of US food and drug administration (Chronic Toxicity Studies with Rodents in Toxicological Principles for the Safety Assessment of Food Ingredients. Redbook 2000, revised July 2007, Chapter IV.C.5.a. IV.C.5.a.) with some modifications. It was now discovered by the inventors that oral administration of Ceo increases significantly the longevity of rats (Fig. 5). At 25 months after the beginning of the treatment, the % of survival is equal to 25 %, 67 % and 100 % for the rats treated with water, olive oil or C6o-dissolved in olive oil, respectively (Fig. 5). At 37 months, after the beginning of the treatment, this percentage is always equal to 100 % for the rats treated with C6o-dissolved in olive oil, 17 % for the rats treated with olive oil, and 0 % for the rats treated with water (Fig. 5). The increase of the expected lifespan reported herein has never been reported for any other substance, to our knowledge.
