Non-Hallucinogenic Cannabinoids

“Studies that support marijuana’s medicinal properties are met with a great deal of skepticism due to cannabis’ hallucinogenic effects. Researchers from St. George’s University of London have isolated six non-hallucinogenic cannabinoids that could lead to the development of effective anti-cancer medication.

“This study is a critical step in unpicking the mysteries of cannabis as a source of medicine,” explained the study’s lead researcher, Dr. Wai Liu. “The cannabinoids examined have minimal, if any, hallucinogenic side effects, and their properties as anti-cancer agents are promising.””

Cannabinoids and the endocannabinoid system in lower urinary tract function and dysfunction.

Posted on by

“AIMS: To review knowledge on cannabinoids and the endocannabinoid system in lower urinary tract function and dysfunction.

 

RESULTS AND DISCUSSION:

Components of the endocannabinoid system-cannabinoid (CB) receptor types 1 and 2, anandamide, and fatty acid amide hydrolase (FAAH), which degrades anandamide and related fatty-acid amides-have been located to lower urinary tract tissues of mice, rats, monkeys, and humans. Studies have located CB receptors in urothelium and sensory nerves and FAAH in the urothelium. CB receptor- and FAAH-related activities have also been reported in the lumbosacral spinal cord. Data on supraspinal CB functions in relation to micturition are lacking. Cannabinoids are reported to reduce sensory activity of isolated tissues, cause antihyperalgesia in animal studies of bladder inflammation, affect urodynamics parameters reflecting sensory functions in animals models, and appear to have effects on storage symptoms in humans. FAAH inhibitors have affected sensory bladder functions and reduced bladder overactivity in rat models. Cannabinoids may modify nerve-mediated functions of isolated lower urinary tract tissues.

CONCLUSIONS:

Evidence suggests components of the endocannabinoid system are involved in regulation of bladder function, possibly at several levels of the micturition pathway. It is unclear if either CB receptor has a dominant role in modification of sensory signals or if differences exist at peripheral and central nervous sites. Amplification of endocannabinoid activity by FAAH inhibitors may be an attractive drug target in specific pathways involved in LUTS.”

Cannabinoid CB2 Receptors Regulate Central Sensitization and Pain Responses Associated with Osteoarthritis of the Knee Joint.

Posted on by

“Osteoarthritis (OA) of the joint is a prevalent disease accompanied by chronic, debilitating pain. Recent clinical evidence has demonstrated that central sensitization contributes to OA pain. An improved understanding of how OA joint pathology impacts upon the central processing of pain is crucial for the identification of novel analgesic targets/new therapeutic strategies.

Inhibitory cannabinoid 2 (CB2) receptors attenuate peripheral immune cell function and modulate central neuro-immune responses in models of neurodegeneration…

These findings suggest that targeting CB2 receptors may have therapeutic potential for treating OA pain.”

Molecular Mechanisms Involved in the Antitumor Activity of Cannabinoids on Gliomas: Role for Oxidative Stress.

Posted on by

“Cannabinoids, the active components of Cannabis sativa, have been shown to exert antiproliferative and proapoptotic effects on a wide spectrum of tumor cells and tissues.

Of interest, cannabinoids have displayed great potency in reducing the growth of glioma tumors, one of the most aggressive CNS tumors, either in vitro or in animal experimental models curbing the growth of xenografts generated by subcutaneous or intrathecal injection of glioma cells in immune-deficient mice.

Cannabinoids appear to be selective antitumoral agents as they kill glioma cells without affecting the viability of non-transformed cells.

This review will summarize the anti-cancer properties that cannabinoids exert on gliomas and discuss their potential action mechanisms that appear complex, involving modulation of multiple key cell signaling pathways and induction of oxidative stress in glioma cells.” http://www.ncbi.nlm.nih.gov/pubmed/24281104

“The therapy of gliomas, the most frequent class of malignant primary brain tumors and one of the most aggressive forms of cancer characterized by high invasiveness, a high proliferation rate and rich neovascularization, could benefit from the use of cannabinoids, the active compounds of Cannabis sativa, and their synthetic derivatives. They have been shown to mimic the endogenous substances named “endocannabinoids” that activate specific cannabinoid receptors (CB1 and CB2).

Cannabinoids have been proven to inhibit glioma tumor growth in either in vitro or in vivo models through several cellular pathways such as elevating ceramide levels, modulating PI3K/Akt, MAPK kinases, inducing autophagy and oxidative stress state in glioma cells, thus arresting cell proliferation and inducing apoptosis. Since cannabinoids kill tumor cells without toxicity on their non transformed counterparts, probably modulating the cell survival/cell death pathways differently, they can represent a class of new potential anticancer drugs.” http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3835116/

The endocannabinoid system, cannabinoids, and pain.

Posted on by

“The endocannabinoid system is involved in a host of homeostatic and physiologic functions, including modulation of pain and inflammation… Exogenous plant-based cannabinoids (phytocannabinoids) and chemically related compounds, like the terpenes, commonly found in many foods, have been found to exert significant analgesic effects in various chronic pain conditions.

Currently, the use of Δ9-tetrahydrocannabinol is limited by its psychoactive effects and predominant delivery route (smoking), as well as regulatory or legal constraints.

 However, other phytocannabinoids in combination, especially cannabidiol and β-caryophyllene, delivered by the oral route appear to be promising candidates for the treatment of chronic pain due to their high safety and low adverse effects profiles.

This review will provide the reader with the foundational basic and clinical science linking the endocannabinoid system and the phytocannabinoids with their potentially therapeutic role in the management of chronic pain.”

Study: Marijuana Compound Can Kill Some Cancer Cells – TIME

Posted on by

Marijuana leaf

“Compounds derived from marijuana can kill cancerous cells in patients with leukemia, according to a recent study.

The study, published in the Anticancer Research journal, was partially funded by GW Pharmaceuticals. which already produces a cannabis-derived drug to help people with multiple sclerosis. Dr. Wai Liu studied six different non-psychoactive cannabinoids (compounds derived from marijuana that don’t get the user high like its THC component does). He found that certain non-psychoactive cannabinoids “resulted in dramatic reductions in cell viability” and “caused a simultaneous arrest at all phases of the cell cycle,” according to the study summary posted online.

Leukemia will take the lives of an estimated 23,720 people this year.

This isn’t the first time marijuana has been linked to deterring cancer: In 2012, researchers at the California Pacific Medical Center in San Francisco found that CBD — a non-psychoactive chemical compound found in cannabis — can stop metastasis in some kinds of aggressive cancer. Liu told the Huffington Post that smoking cannabis is unlikely to have the same cancer-inhibiting effect.”

In vivo type 1 cannabinoid receptor availability in Alzheimer’s disease.

Posted on by

“The endocannabinoid system (ECS) is an important modulatory and potentially neuroprotective homeostatic system in the brain.

  We have investigated CB1R availability in vivo in patients with AD…

 In conclusion, we found no in vivo evidence for a difference in CB1R availability in AD compared to age-matched controls.

 Taken together with recently reported in vivo CB1R changes in Parkinson’s and Huntington’s disease, these data suggest that the CB1R is differentially involved in neurodegenerative disorders.”

FDA approves marijuana based drug

Posted on by

“The U.S. Food and Drug Administration has approved clinical trials of a cannabis-based drug and its effects on epilepsy. The treatment, Epidiolex, is 98 percent purified cannabidiol (CBD) made by GW Pharmaceuticals based out of the U.K.  

There are around 60 known chemicals contained in cannabis called cannabinoids. Tetrahydrocannabinol, also known as THC, is the main component responsible for the drug’s psychoactive nature. CBD, however, is the second most abundant cannabinoid in the cannabis and provides medicinal benefits without the “high.” Epidiolex will come in a viscous liquid form to be dispensed from syringes. A 25 milligram per meter or 100 milligram per meter will be the two strengths made available to those in the trials.

The FDA has approved of intermediate-sized clinical trials sponsored by two doctors. Dr. Orrin Devinsky, a professor in the Department of Neurology, Neuroscience and Psychiatry in the New York University School of Medicine and director of the NYU Comprehensive Epilepsy Center, and Dr. Roberta Cilio, a pediatric neurologist at the University of California, San Francisco, are set to follow 25 patients using Epidiolex as treatment for pediatric epilepsy.

On Oct. 4, at the NYU Langone Medical Center, Devinsky led a conference entitled, “Cannabidiols: Potential Use in Epilepsy & Other Neurological Disorders.” During the affair, Devinsky and Cilio led a presentation on planned trials on CBD in children with treatment resistant epilepsy. 

The D.C. – based Marijuana Policy Project’s Communications Director Mason Tvert responded to the news of the approved trials. “We’ve long known that marijuana has a variety of medical benefits,” Tvert said. Tvert added that the federal government clearly recognizes marijuana’s medicinal benefits and it’s a shame they hindered most research of it.

Maryland’s new marijuana law came into effect on Oct. 1, but its miniscule scope won’t have much effect. It deals with a small number of patients that would enroll in state-approved clinical studies. However, with no hospitals signed up to hold these studies, no visible changes are set to occur in the near future.

Now the country will wait and see if CBD can live up to the hype, and if the epileptic patients can find any relief from their disease.”

“While a large body of anecdotal and laboratory evidence points to cannabis as an effective treatment for epilepsy, research in humans is just beginning to catch up.

 GW Pharmaceuticals – the UK-based company behind the natural cannabis spray Sativex – announced the start of the first round of clinical trials of a new cannabis treatment for epilepsy.

In the press release, Dr. Stephen Wright, Director of Research and Development at GW, said the company has spent years testing cannabis in pre-clinical models – which include cell cultures and animals.

So far, the drug is only known as GWP42006.

“We are pleased to have advanced GWP42006 to first dose in man, a significant milestone in the development of this novel product candidate. The decision to progress into Phase 1 follows several years of highly promising pre-clinical research.”

Dr. Ben Whalley, Senior Lecturer in Pharmacology at the Reading School of Pharmacy, added, “Our research collaboration with GW over the last several years has shown that GWP42006 not only exerts significant anticonvulsant effects in a wide range of preclinical models of seizure and epilepsy but is also better tolerated compared to existing anti-epileptic drugs.”

While the company has not disclosed the ingredients in the new drug, their latest animal study – which appears in the October issue of the British Journal of Pharmacology – showed positive results with two chemicals derived from cannabis: Cannabidiol (CBD) and cannabidivarin (CBDV).

Both were found to suppress seizures and increase survival across a range of different rat models of epilepsy.”

Both CBD and CBDV are produced naturally by cannabis. Unlike THC, these two compounds do not get patients high.

“GW Pharmaceuticals plc (Nasdaq: GWPH, AIM: GWP, “GW”) announced today it has commenced a Phase 1 clinical trial of product candidate GWP42006 for the treatment of epilepsy.

Over the last five years, GW has conducted an extensive pre-clinical cannabinoid research program in the field of epilepsy in collaboration with the University of Reading in the United Kingdom. This research has led to the emergence of a number of promising cannabinoid therapeutic candidates showing anti-epileptic effects.

GWP42006, one of the most promising of those candidates, is a non-psychoactive cannabinoid extracted from specific chemotypes of the cannabis plant which has shown the ability to treat seizures in pre-clinical models of epilepsy with significantly fewer side effects than currently approved anti-epileptic drugs1.

“We are pleased to have advanced GWP42006 to first dose in man, a significant milestone in the development of this novel product candidate. The decision to progress into Phase 1 follows several years of highly promising pre-clinical research,” stated Dr. Stephen Wright, Director of Research and Development at GW. “We believe that GWP42006 has the potential to become an important advance in the treatment of epilepsy, a condition for which there remains a substantial unmet medical need.””
