Abstract

Cannabinoids have been found to have antioxidant properties, unrelated to NMDA receptor antagonism. This new found property makes cannabinoids useful in the treatment and prophylaxis of wide variety of oxidation associated diseases, such as ischemic, age-related, inflammatory and autoimmune diseases. The cannabinoids are found to have particular application as neuroprotectants, for example in limiting neurological damage following ischemic insults, such as stroke and trauma, or in the treatment of neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and HIV dementia. Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid toxicity that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention. A particular disclosed class of cannabinoids useful as neuroprotective antioxidants is formula (I) wherein the R group is independently selected from the group consisting of H, CH3, and COCH3. ##STR1##

Anything to stop the US citizen from getting natures CURE for cancer and hundreds if not thousands of other diseases without throwing money in the pockets of pharma now for their unnatural pills or later for cannabis cures in exchange for insane amounts of moneys or for the elite allowed to survive.

"Nonpsychoactive cannabinoids, such as cannabidoil, are particularly advantageous to use because they avoid "TOXICITY" that is encountered with psychoactive cannabinoids at high doses useful in the method of the present invention." Isn't the patent office suposed to, by law, through the process, protect us from fraudulent, inacurate, and Unsubsstantiated claims made within any patent? Somebody help me here, is there a single TOXIC cannabinoid? If so, please name it and spread the word.

Here's another cannabinoid related patent with assignee: United States of America. This one relates to vasoconstrictor properties. http://www.patentstorm.us/patents/7109245/fulltext.html There are hundreds of cannabinoid related patents issued. Most to universities and parma companies.

You can't patent cannabis any more than you can patent the multiplication tables or mockingbirds. Patents have to be unique inventions, not attempts to monopolize nature or logic. They also should have absolutely nothing to do with fascism, enforced misery, torture, or a police state, which seems to be the intent here. This ruling is emminently challengable in the Patent Court, and the citizenry should waste no time in ousting this abortion of a patent ruling from the Patent office, where it has no place at all. There are limits to the patentability of objects, and nearly all of them have been exceeded here, for a multiplicity of reasons.

Is this some type of brilliant hoax to discredit the U.S. government's stance on marijuana as a useful medicine? Dr. Jekyll, may I introduce Mr. Hyde (the truth).

this makes me sick that our nation is so greedy that they have patented cannabis. obviously they are convinced it has medical value. but for now the greedy prisons, DEA, & judicial system make too much money. the BIG PHARMA, TOBACCO, PAPER, ALCOHOL COmpanies make too much money as do their congressman funded via the respective lobbyists. we’re not taking it anymore. yes we cannabis & HEMP 2010 throughout the americas.

Why don't you patent water or oxygen. How about Wheat, then no one in the world can have bread without getting a license. WTF?
by mark on 05/06/2009 02:20 PM
well the u.s. holds a patent on cannabanoids.there is nothing in the law that says they must produce .so in other words yea we have it but will not use so what !!!
