Khalid El Sayed, an associate professor of medicinal chemistry at the ULM College of Pharmacy, and ULM colleagues Paul Sylvester and Girish Shah received a patent for their discovery of anti-cancer compounds in fresh tobacco leaves earlier this week from the U.S. Patent and Trademark Office.
"The leaf and flower of the tobacco plant contain high amounts of the key flavor ingredient called cembranoids, which shows promise as an anti-cancer agent," El Sayed said. "It was very exciting to discover the anti-cancer activities."
But this doesn't mean people will reap the same benefits by using commercial tobacco, he warned, adding that much of the anti-cancer compound is lost in the processing of commercial tobacco.
"This compound is not commonly found in commercial tobacco because commercial tobacco is largely degraded into smaller compounds for about a year to give it flavor during the processing and fermentation," he said.
The cembranoids are found in the waxy substance on fresh tobacco leaves and show potential for controlling metastic breast and prostate cancers. The plant produces them as a chemical defense to protect itself against insects and harmful microbial infections, El Sayed said.
El Sayed said the idea originated after examining soft-bodied corals, which also produce cembranoids to guard themselves against predators.
"We were collecting soft-bodied corals and found that it was using something to deter predators away, and these marine cembranoids are known for their anti-cancer activity," he said. "So then we became interested in isolating the same compound in tobacco leaves."
And sure enough, that's just what they did.
"This is a remarkable discovery," said Karen Briski, head of the department of basic pharmaceutical sciences. "It demonstrates that there is a helpful, healthy application for tobacco."
Shah, professor of pharmacology, said the discovery came as quite a shock. "I was tremendously surprised considering tobacco is a well-known carcinogen," he said. "This goes against the current dogma."
El Sayed said he hopes to sell the rights to the patent to a company that can support more pre-clinical and clinical testing of the compound so it can be used to develop beneficial applications.
El Sayed said his team also is working with other researchers to explore how the compounds can be used to protect neurological activity in addition to how they can be used to control tobacco addiction.
"Fresh tobacco is an important and relevant agricultural crop for many states in the U.S.," he said. "With this discovery, growers can now start producing tobacco for pharmaceutical use."
Comment: Apart from cembranoids, tobacco also contains nicotine and solanesol, which have proved as medicinal in many conditions that cause death and suffering. Just have a look at the following studies:
Tobacco used as medicine

Tobacco plant-made therapeutic thwarts West Nile virus
Health Benefits of Smoking Tobacco
Tobacco-derived compound prevents memory loss in Alzheimer's disease mice
Does Smoking Help Protect the Joints?
Nicotine helps Alzheimer's and Parkinson's Patients

Longtime Smokers Less Likely to Develop Parkinson's Disease
Study: Quitting smoking increases risk of developing type 2 diabetes
Smoking Helps Protect Against Lung Cancer
Smoking does NOT cause lung cancer, in fact it just might protect you from nuclear fallout
And note that here at SOTT, we agree with the above article's advice. When we say, "Let's All Light Up!", we mean natural, organically grown tobacco, not commercial cigarettes.

is actually prescripting tobacco patches in order to ease the life of Alzheimer patients. Guess what ? The social security deny his prescriptions becauses the patches are not used to ease the whitdrawal from smoking !
You know tobacco is pure evil, nicotine is his henchman. They prefer leaving Alzheimer patients decaying than trying a new therapy for them via nicotine patches.
It just will be the same fot cancer until a pharmalogical firm design a pill that can be patented.
We really have enjoyed this website it gives you so much good information. I saw a comment where a lady was asking where she could find Tobacco Leaves so I just thought I would post a comment about our website. We sell Tobacco leaves to the public. Our website is www.wholesalecigarettetobacco.com
I have one question and I apologize if it's a stupid one, but where does one get a natural brand organic tobacco cigarette?
What brand?
I smoke one Marlboro Light in the morning with my coffee and I know it's a commercial and unnatural non organic cigarette.
I've heard of "Native Spirit" but you have to roll your own.
Please advise.
Thank you.
