Therapeutic utility of cannabinoid receptor type 2 (CB(2)) selective agonists.

Posted on by

“The cannabinoid receptor type 2 (CB2) is a class A GPCR that was cloned in 1993 while looking for an alternative receptor that could explain the pharmacological properties of Δ(9)-tetrahydrocannabinol.

CB2 was identified among cDNAs based on its similarity in amino acid sequence to the CB1receptor and helped provide an explanation for the established effects of cannabinoids on the immune system.

In addition to the immune system, CB2 has widespread tissue expression and has been found in brain, peripheral nervous system, and gastrointestinal tract.

Several “mixed” cannabinoid agonists are currently in clinical use primarily for controlling pain, and it is believed that selective CB2 agonism may afford a superior analgesic agent devoid of the centrally mediated CB1 effects.

Thus, selective CB2 receptor agonists represent high value putative therapeutics for treating pain and other disease states. In this Perspective, we seek to provide a concise update of progress in the field.”

The yin and yang of cannabis-induced psychosis: the actions of Δ(9)-tetrahydrocannabinol and cannabidiol in rodent models of schizophrenia.

Posted on by

“There is substantial epidemiological evidence showing that cannabis increases the risk of psychosis, whereas other research suggests that schizophrenia patients self-medicate with the substance. These conflicting accounts may at least be partially explained by the two phytocannabinoids cannabidiol (CBD) and Δ(9)-tetrahydrocannabinol (THC) and their opposing actions on schizophrenia-related symptoms.

…propsychotic actions of THC… antipsychotic actions of CBD.

…animal studies… showing that CBD antagonises the neurobehavioural effects of THC, while others show the opposite, that CBD potentiates the actions of THC.

Various mechanisms are put forth to explain these divergent effects such as CBD antagonism at central CB1 receptors…”

…the present study suggests a beneficial property of a direct cannabinoid receptor agonist… and of CBD…”

A drug discovery case history of ‘delta-9-tetrahydrocannabinol, cannabidiol’.

“…the Cannabis sativa herb has been known for its therapeutic benefit for centuries… interest in the clinical potential of cannabinoid-based drugs escalated after the discovery of the endocannabinoid system… therapeutic applications of cannabinoids (plant-derived or synthetic)… may constitute a useful addition to the pharmacotherapeutic armamentarium in chronic conditions insufficiently alleviated by existing drugs.”  http://www.ncbi.nlm.nih.gov/pubmed/22646020

Δ9-tetrahydrocannabinol and its major metabolite Δ9-tetrahydrocannabinol-11-oic acid as 15-lipoxygenase inhibitors.

“Δ(9)-Tetrahydrocannabinol (Δ(9)-THC), a major component of marijuana, has suggested to suppress atherosclerosis…. Δ(9)-THC seems to be attractive for the prevention of atherosclerosis…

In the present study, Δ(9)-THC was found to be a direct inhibitor for 15-LOX…

Furthermore, Δ(9)-THC-11-oic acid, a major and nonpsychoactive metabolite of Δ(9) -THC, but not another Δ(9)-THC metabolite 11-OH-Δ(9)-THC (psychoactive), was revealed to inhibit 15-LOX.

Taken together, it is suggested that Δ(9) -THC can abrogate atherosclerosis via direct inhibition of 15-LOX, and that Δ(9)-THC-11-oic acid is shown to be an “active metabolite” of Δ(9) -THC in this case.”

Endocannabinoid system in cancer cachexia.

Image result for current opinion in clinical nutrition & metabolic care

“More than 60% of advanced cancer patients suffer from anorexia and cachexia.

This review focuses on the possible mechanisms by which the endocannabinoid system antagonizes cachexia-anorexia processes in cancer patients and how it can be tapped for therapeutic applications.

Cannabinoids stimulate appetite and food intake…

Cannabinoid type 1 receptor activation stimulates appetite and promotes lipogenesis and energy storage.

Further study of cancer-cachexia pathophysiology and the role of endocannabinoids will help us to develop cannabinoids without psychotropic properties, which will help cancer patients suffering from cachexia and improve outcomes of clinical antitumor therapy.”

HIV/AIDS Cure May Be Found In Marijuana: Study

“For years, many Americans with HIV/AIDS have used medical marijuana to relieve some common symptoms associated with the illness such as nausea, vomiting and appetite loss.

Now, a new study published last week in the journal AIDS Researcher and Human Retroviruses found that a daily dosage of marijuana’s psychoactive ingredient tetrahydrocannabinol, or THC, may actually fight the HIV/AIDS virus itself.”

HIV Infections Cured With Cannabis a Real Possibility

Posted on by

“Researchers are looking into the use of THC (tetrahydrocannabinol), the active ingredient in marijuana, to help stop the spread of HIV infection.

Hundreds of marijuana researchers have reported that THC was able to pierce the RIV virus in monkeys. That particular virus is almost identical to the HIV virus found in humans, so this news is very encouraging.

The greatest drawbacks to this excellent news are the current laws preventing testing on human candidates.

With the changing of these restrictive laws, HIV infections have a great chance of being cured, with cannabis as a real possible player in the race to stop the disease.”

Marijuana as a possible treatment for HIV and cancer

“There’s been some interesting research on using THC (tetrahydrocannabinol), the principal psychoactive drug in marijuana, to help fight HIV, and damage cancer cells in some leukemias and possibly malignant tumors.

…the possibility exists that information from both of these research studies may produce beneficial results in the treatment of HIV and cancer.”

Weed Could Block H.I.V.’s Spread. No, Seriously.

Posted on by

“But the U.S. government won’t let scientists try out this promising treatment on humans… proving that an illegal drug can stop a deadly disease in humans—without testing it on them—is impossible…

THC is one of 500 active ingredients in marijuana. And marijuana, despite many studies proving its medical value, is sill classified by the government as a Schedule 1 Substance.

In the face of mounting evidence that it is beneficial in treating diseases… it remains a controlled substance.

During HIV infection, one of the earliest effects is that the virus spreads rapidly throughout the body and kills a significant part of cells in the gut and intestine. This activity damages the gut in a way that allows the HIV to leak through the cell wall of the intestines and into the bloodstream.

When THC is introduced into this environment, it activates the CB2 receptors in the intestines to build new, healthy bacterial cells that block the virus from leaking through the cell walls. In other words, the body works hard to keep bad stuff in the intestines and the good stuff out.

Put another way: HIV kills the cells that protect the walls— THC brings them back. Reducing the amount of the virus in the lower intestines could then help keep uninfected people uninfected.”
