NEW "SUPER" ASPIRIN FIGHTS CANCER

A potent new weapon against cancer has been developed by scientists

Saturday March 10,2012
By Sarah Westcott

A POTENT “super aspirin” that can cause cancer cells to self-destruct has been developed by scientists.

The hybrid version is much more ­powerful than the conventional painkiller but far less toxic.

Prolonged use of traditional aspirin can cause stomach ulcers and kidney failure.

But the new compound, known as NOSH, can be used in lower doses and has fewer side effects.

In tests on mice, it has been shown to shrink cancer cells by 85 per cent.

The pill is effective against 11 different forms of cancer, including colon, pancreatic, prostate, breast and ­leukaemia, researchers have found.

Hailing the breakthrough yesterday, ­Professor Khosrow Kashfi said: “If what we have seen in animals can be translated to humans it could be used in conjunction with other drugs to shrink tumours before chemotherapy or surgery.”

Professor Kashfi, of the Sophie Davis School of Biomedical Education at The City College of New York, added: “The key components of this new compound are that it is very, very potent and yet it has minimal toxicity to normal cells.”

Previous research has shown that ordinary aspirin can reduce the size of some tumours by up to half. But prolonged use of the old form of the drug can have serious side effects such as excessive bleeding.

Professor Kashfi said: “There’s a lot of data on aspirin showing that when taken on a regular basis, on average it reduces the risk of development of colon cancer by about 50 per cent compared to non-users.”

Only 24 hours after treating a culture of cancer cells, the NOSH aspirin demonstrated 100,000 times greater potency than aspirin alone.

Professor Kashfi said: “At 72 hours it is about 250,000 times more potent in an in-vitro cell culture against human colon cancer. So you need a lower amount to get the same result.”

The new drug is a hybrid of two compounds, one of which releases nitric oxide to protect the stomach lining and the other releases hydrogen sulfide to increase its cancer-fighting ability.

Lower doses would minimise or potentially eliminate its side effects.

In a second study, when mice bearing human colon cancer tumours on their flanks were given NOSH aspirin, the compound caused cancer cells to self-destruct, inhibited the proliferation of the cells and significantly reduced tumour growth without any signs of toxicity.

Writing in the journal ACS Medicinal Chemistry Letters, Professor Kashfi said any working therapy for humans was still years away, but toxicity testing and clinical trials would be the next step.

His findings will be presented at the annual meeting of the American Association for Cancer Research in Chicago next month.

Dr Kat Arney, science information manager at Cancer Research UK, said: “Scientists have been investigating the cancer-fighting properties of aspirin for many years, although prolonged use can cause side effects such as stomach bleeds.

“It will be interesting to see how this particular compound progresses, although much more research is needed to show whether it’s safe and effective for use in humans.”

Putting my "Mr Cynic" hat on here: I am rather wary of this.

Normal aspirin is a very cheap and (I think) non-patentable medicine with some very useful properties, including anti-inflammatory ones.


I suspect that stories of its toxicity have been exaggerated (perhaps by those who would like to sell you something more expensive).


I used to think I was intolerant to normal aspirin, but found you can build up to it slowly.
Crushing it up and mixing it with warm water or milk can help.



Beware of Big Pharma trying to make you forget about or discount the cheap and cheerful remedies that we've had for years (and that actually work). Sodium bicarbonate is another.
Salt is another.
