Scientists believe marijuana compound could fight cancer

“Scientists in California believe they may have discovered a compound in marijuana that can reduce the aggressiveness of some forms of cancer.

The San Francisco Gate reports on the data that has been years in the making. While marijuana has been shown to help reduce nausea and pain in cancer patients, scientists believe that a compound in marijuana has the ability to “turn off” the activity of a gene responsible for metastasis in breast and other types of cancers.

The research team is working out of San Francisco’s California Pacific Medical Center Research Institute and have been working for years on the study. The compound they’re focused on, called cannabidiol, does not produce the psychotropic high associated with marijuana.

Last year, the team published a small study showing the positive effects of cannabidiol on mice. New data is about to be released that expands upon the previous results that the researchers hope will help propel the study even further.

“The preclinical trial data is very strong, and there’s no toxicity. There’s really a lot of research to move ahead with and to get people excited,” said Sean McAllister, who is working alongside scientist Pierre Desprez in the study.

Desprez and McAllister believe that their merging of separate areas of study was serendipitous.

Desprez had been studying the protein ID-1, which he found to play an important role in how cancer could spread. McAllister, on the other hand, was focused on studying anabolic steroids in drug abuse. He soon became focused on with the role non-psychotropic cannabidiol, or CBD, interacts with cancer.

McAllister, after hearing an internal seminar from Desprez on his studies of ID-1, came up with the question “How effective would cannabidiol be on targeting metastatic cancer cells?”

The two then teamed up, with Desprez armed with ID-1 cancer-causing protein, and McAllister with CBD, his cancer-fighting compound.

For their experimentation, the doctors exposed ID-1 to CBD in a petri dish. In a shocking result, the ID-1, the cancer-causing protein, reverted to a normal state and stopped acting “crazy.”

“We thought we did the experiment the wrong way,” McAllister said of the overwhelming results.

However, their results proved to be consisted.

“I told Sean, ‘Maybe your drug is working through my gene,’ ” Desprez said.

What the researchers have discovered thus far in their research is that CBD turns off the overexpression of ID-1, which prevents it from traveling to foreign tissues. Thus, the metastasization – cancer’s fatal ability – is blocked.

In the wake of their positive results, the doctors were forced to emphasize that the CBD will only work in the presence of high levels of ID-1 and these do not include all cancerous tumors but, rather, aggressive, metastatic cells. High levels have been found in leukemia, colorectal, pancreatic, lung, ovarian, brain and other cancers.”

“(OTC: MJNA), a leading hemp industry innovator, is pleased to report on a September 18 San Francisco Chronicle Article, “Pot compound seen as tool against cancer.” The article states that scientists at California Pacific Medical Center who have been researching marijuana’s compounds for the 20 years have found that Cannabidiol, or CBD, has the ability to “turn off” the DNA that causes “breast and other types of cancers” to metastasize. CBD is the second-most abundant cannabinoid within marijuana, but does not cause the psychotropic high of THC.

As stated in the article: “We started by researching breast cancer,” said scientist Pierre Desprez. “But now we’ve found that Cannabidiol works with many kinds of aggressive cancers–brain, prostate–any kind in which these high levels of ID-1 are present.” Desprez said he is hopeful clinical trials will begin immediately. He currently has grant funding through the National Institutes of Health, Susan G. Komen for the Cure, the U.S. Department of Defense and the California Breast Cancer Research Program.

As previously announced in the MJNA press release dated September 5, MJNA portfolio company, Red Dice Holdings, recently launched its Hemp-based high concentrate CBD health and wellness products, Dixie X, for over-the-counter sales. These Cannabidiol products represent the highest strength of CBD products on the market today, and this same concentrate will soon be used to launch the CanChew Biotechnologies line of CBD-enriched chewing gum. Click here for recent production news from PhytoSphere. Dixie X can currently be purchased in over 100 retail locations in Colorado, Arizona and New Mexico as well as on-line by anyone living in the U.S.

In short, MJNA and its portfolio company, PhytoSphere Systems, currently produces non-THC, high quality CBD enriched Hemp oil that according to this story, may fight the most aggressive forms of cancers we know of today.

Studies, such as those in this article and at Project CBD, have continually shown that these non-psychoactive CBD wellness products provide powerful relief for pain and anxiety sufferers, but without the euphoric effects provided by THC. The CBD health and wellness industry is estimated by MJNA to be a $5 billion market.”

(NBC) “Research shows component in medical cannabis fights cancer.”

“The “medical” bit of medical marijuana may be legitimate after all: Turns out a component of cannabis fights cancer, according to research.

Scientists at California Pacific Medical Center found that cannabidiol, or CBD, has the ability to “turn off” the DNA that causes “breast and other types of cancers” to metastasize, according to the San Francisco Chronicle.

“If this plant were discovered in the Amazon today, scientists would be falling all over each other to be the first to bring it to market,” said Dr. Donald Abrams, chief of oncology at the University of California San Francisco, which has also found science behind marijuana’s efficacy.

The drug “has been shown to reduce pain and nausea” in cancer patients, the newspaper reported. AIDS patients also swear by cannabis for its ability to allow them to eat, sleep and otherwise function.

Turns out that cannabidiol has none of the psychotropic effects of marijuana as a whole, according to the newspaper. The researchers hope to move to clinical trials on humans soon.

Cancer cells exposed to cannabidiol lost their abilities to metastasize, according to the newspaper.”

Cannabinoids, Endocannabinoids, and Related Analogs in Inflammation.

“This review covers reports published in the last 5 years on the anti-inflammatory activities of all classes of cannabinoids, including phytocannabinoids such as tetrahydrocannabinol and cannabidiol, synthetic analogs such as ajulemic acid and nabilone, the endogenous cannabinoids anandamide and related compounds, namely, the elmiric acids, and finally, noncannabinoid components of Cannabis that show anti-inflammatory action. It is intended to be an update on the topic of the involvement of cannabinoids in the process of inflammation. A possible mechanism for these actions is suggested involving increased production of eicosanoids that promote the resolution of inflammation. This differentiates these cannabinoids from cyclooxygenase-2 inhibitors that suppress the synthesis of eicosanoids that promote the induction of the inflammatory process.”

 

“INTRODUCTION

This review is intended to be an update on the topic of the involvement of cannabinoids in the process of inflammation. Other reviews cover certain aspects of this subject and the reader is referred to them for a discussion of earlier reports. In this review are reports published in the last 5 years on the activities of all classes of cannabinoids, including the endogenous cannabinoids such as anandamide, related compounds such as the elmiric acids (EMAs), and noncannabinoid components of Cannabis that show anti-inflammatory action. An interesting recently published example of the latter one is caryophyllene, an abundant component of Cannabis oil that shows anti-inflammatory activity and has high affinity for cannabinoid receptor 2 (CB2; 5).”

 

“Phytocannabinoids: Tetrahydrocannabinol and Cannabidiol”

 

“PLANT PREPARATIONS AND NONCANNABINOID CONSTITUENTS OF CANNABIS”

“Cannabis sativa is a complex botanical, and it is not unlikely that the therapeutic benefits of marijuana are due to some of the more than 60 cannabinoids and 200–250 noncannabinoid constituents of the plant. One noncannabinoid, the geranylated flavone cannflavin A (Fig. 5), is 30 times more potent than aspirin as an inhibitor of prostaglandin E2 . These potentially important findings have been overlooked, as most attention in marijuana research has been directed to the analgesic effects of the plant and to mechanisms of psychoactivity. A further example that this line of inquiry has remained dormant is a series of overlooked observations, which demonstrate potent anti-inflammatory actions of a crude marijuana extract and of the nonpsychoactive Cannabis constituents, CBD, cannabinol, and cannabichromene in the carrageenan paw edema model of acute inflammation in rats. Volatile oil products of the plant also have biological activity. Thus, pyrolysis products may add to the therapeutic properties of smoked marijuana. Several of the most abundant cannabinoid and noncannabinoid constituents of C. sativa are nonpsychoactive.”

“Flavonoids are ubiquitous plant phenolic compounds that consist of two aromatic rings linked by a three carbon bridge. They are attracting interest because of their antioxidant, antitumor, anti-inflammatory, and antimicrobial activities. The flavone luteolin, a constituent of C. sativa, is also found in spices and in vegetables such as celery and green pepper. When added to peripheral blood mononuclear cells in vitro, luteolin suppresses production of the inflammatory cytokines TNFα, IL-1b, and IL-6, actions that relate to a selective reduction in numbers of monocytes. Perhaps more importantly, luteolin inhibits growth of Plasmodium falciparum in vitro and protects against induction of colon cancer in mice.”

“CONCLUSIONS

Possibly the very earliest literature reference on Cannabis describes its use as an anti-inflammatory agent. The Chinese emperor Shen-nung (ca. 2000 B.C.), in a work called Pen-ts’ao Ching, noted many of the effects of Cannabis in humans. Among other properties, it was claimed that cannabis “undoes rheumatism”, suggesting possible anti-inflammatory effects. The reports described in this review of the current literature provide support for the claims made by the ancient Chinese healers. These more recent publications include relief from chronic neuropathic pain, fibromyalgia, rheumatoid arthritis, and postoperative pain. In addition, a large body of preclinical data on all classes of cannabinoids, including the endogenous examples, point to a variety of therapeutic targets for cannabinoids and important roles for the endocannabinoids in the physiology of inflammation.”

Cannabis could be used to treat obesity

“Cannabis could be used in drugs to help people overcome obesity, according to new UK research.

Researchers at GW Pharmaceuticals have discovered two compounds in cannabis leaves that help our bodies burn more energy, the UK’s Daily Telegraph reported.

The company is developing a drug to treat “metabolic syndrome”, which occurs when people suffer obesity, diabetes and high blood pressure, which increases their risk of heart disease and stroke.

Tests in mice showed the cannabis compounds improved their metabolism, which resulted in lower cholesterol in the bloodstream, plus less fat in key organs, such as the liver.

Now a trial is underway with 200 people and researchers hope the drug can treat metabolic syndrome.

Dr Stephen Wright, director of research and development at GW Pharmaceuticals, said they expect results in late 2012.

“The results in animal models have been very encouraging. We are interested in how these drugs effect the fat distribution and utilisation in the body as a treatment for metabolic diseases,” Dr Wright said.

“Humans have been using these plants for thousands of years so we have quite a lot of experience of the chemicals in the plants.”

Cannabis is illegal in the UK but GW Pharmaceuticals has been granted permission to grow it in secret greenhouses in the country’s south.

They are growing a type of cannabis with different quantities of compounds called cannabinoids.

While cannabis is known for inciting the “munchies”, these compounds, called THCV and cannabidiol, appear to suppress the appetite, while helping control sugar levels in the blood and fat levels throughout the body.

It appears THCV also helps cells that produce insulin work more effectively.

Now researchers are hoping the drugs will help people suffering type 2 diabetes and other obesity-related diseases.”

How marijuana could help cure obesity-related diseases

“According to a new British study, marijuana leaves (not the buds that Willie Nelson loves so dearly) contain two compounds that boost the metabolism of mice, leading to lower levels of fat and cholesterol in the body — the latest addition to a growing body of evidence that marijuana may be useful in countering ailments related to obesity. One study in March found that a brain chemical similar in structure to an active compound in cannibis could help people shed weight, while another study last September concluded that pot smokers were less likely to be obese than non-potheads, though for reasons that remain unclear.   

The two compounds, THCV and cannabidiol, boosted the rodents’ metabolisms — reducing fat levels in their livers and cholesterol levels in their bloodstreams — and also made the mice more sensitive to insulin and protected the cells that produce insulin, “allowing [the cells] to work better and for longer.” The combined effects improved the mice’s ability to burn off energy.

And the compounds didn’t make mice hungry the way smoking weed affects humans?
Actually, the compounds were found to have an appetite-suppressing effect, but the effect only lasted for a short time.”

Cannabis drug could help fight obesity

“Apparently scientists have discovered that a natural component of cannabis suppresses the appetite and that discovery may lead to a new class of drugs for treating obesity.

Scientist professor Roger Pertwee, a neuropharmacologist at Aberdeen University, says it was already well known that cannabis stimulated the appetite, but not widely known that the plant also contained substances that produced the opposite effect.

That substance is apparently called THCV and is chemically similar to another cannabis chemical, or cannabinoid, called THC that stimulates the appetite.

As drugs based on THC are already being used to increase the appetite of AIDS patients, the focus is now on developing THCV for use as an anti-obesity drug, said Professor Pertwee.

Pertwee says that cannabis is rich in substances that can mimic the natural or endogenous cannabinoids in the brain, that act as chemical messengers in the nervous pathways, involved in such activities as appetite control or pain relief.

These endogenous cannabinoids seem to act on the reward pathways to the brain, to increase the reward you get when you take food, but can have harmful effects.

By increasing appetite they can increase fat, which can give rise to obesity or overweight.

Drugs are apparently now being developed that can increase the levels of these chemicals in our brains by slowing down the rate at which they disappear once they have been released,says Pertwee.

Professor Pertwee has also found a method of potentially boosting the signals in the brain that are generated by these endogenous cannabinoids.”

“Two cannabis compounds can raise the quantum of energy the body burns and keep obesity at bay. Called THCV and cannabidiol, they were found to have an appetite suppressing effect too for a short while.

Animal tests have shown these compounds can help treat type two diabetes while also lowering levels of cholesterol in the blood stream and fat in key organs like the liver.

Scientists also found the compounds also had an impact on the level of fat and its response to insulin, a hormone that controls blood sugar levels, the Telegraph reports.

THCV was also found to increase the animals’ sensitivity to insulin while also protecting the cells that produce insulin, allowing them to work better and for longer.

Steph Wright, director of research and development at GW Pharmaceuticals developing the drugs, said: “The results in animal models have been very encouraging. We are interested in how these drugs effect the fat distribution and utilisation in the body as a treatment for metabolic diseases”.”
