Novel Chemical Derivatives of Existing Cannabinoids
Our second program seeks to create novel derivatives of two cannabinoids, CBG (which is a precursor to CBD and THC) and THCV, which we intend to evaluate for their potential therapeutic benefits. We are initially targeting the creation of approximately four and ten new proprietary CBG and THCV compounds, respectively, as part of this program.
CBG is a non-psychoactive cannabinoid found in cannabis that is believed to boost anandamide, a naturally occurring endocannabinoid that increases dopamine levels and is responsible for regulating various bodily functions related to mood, sleep and appetite. In addition, CBG is also believed to be a possible inhibitor of the psychoactive effects of THC. CBG is believed to have potential benefits in the areas of pain relief, inflammatory bowel disease/colitis, anti-cancer and anti-bacterial activities, neurodegenerative diseases (e.g., Huntington’s disease), cachexia, depression, overactive bladder and various forms of epilepsy.
THCV is a psychoactive cannabinoid found in cannabis that shares a similar molecular structure to THC. Despite the structural similarities to THC, the psychoactive properties of THCV are more difficult to define. In low doses, THCV is believed to be an antagonist of the CB1 receptor. In high doses, however, THCV is believed to be an agonist of the CB1 receptor similar to THC. Unlike THC, which increases appetite, THCV has the opposite effect of suppressing appetite making it a popular research target for weight loss and diabetes drugs. Further, THCV is also believed to have anti-inflammatory, anti-anxiety and anti-seizure properties, as well as being effective at reducing tremors associated with central nervous system conditions such as amyotrophic lateral sclerosis, or ALS, Parkinson’s disease and Alzheimers.
That fact that CBG and THCV already demonstrate biological activity gives us reason to believe that their derivatives will also be biologically active. These derivatives may also demonstrate different biological activity than their respective parent compounds.
Once we complete the chemical design and synthesis of these derivative cannabinoid compounds, we intend to test them in in vitro receptor binding assays, which we plan on commencing in the second half of 2019, to determine the best potential indications for further development.
National Institutes of Health Program
We own an exclusive, worldwide license from the NIH to three patents covering a series of cannabinoid receptor mediating compounds developed by Dr. George Kunos, Scientific Director of the National Institute on Alcohol Abuse and Alcoholism of the NIH and leading researcher on endocannabinoids and the endocannabinoid system.
These novel dual-action cannabinoid receptor mediating compounds are proprietary NCEs that are CB1 receptor antagonists and inhibitors of inducible nitric oxide synthase, or iNOS. Over activation of CB1 and iNOS has been implicated in the pathophysiology of SSc, which includes fibrosis of the skin, lung, kidney, heart, and the gastrointestinal tract.
Our license enables us to use these cannabinoid receptor mediating compounds for the commercial development as a new therapeutic for the treatment of SSc and other skin fibrotic diseases.
Systemic Sclerosis
SSc is a chronic, systemic autoimmune disease characterized by activation of innate and adaptive immune systems, an obliterative, proliferative vasculopathy of small blood vessels, and fibrosis of the skin and multiple internal organs. Approximately 90,000 people in the United States and Europe have SSc. The disease affects mainly adults (80% of SSc patients are women) with mean age of onset about 46 years of age in the United States. Based on these patient population characteristics, SSc is classified as an orphan indication.
SSc can affect multiple internal organs in the body, including the lungs, heart, kidneys, joints, muscles, esophagus, stomach and intestines. Clinically apparent organ involvement that occurs in more than a third of these patients includes thickened skin, Raynaud’s phenomenon, esophageal symptoms, pulmonary fibrosis, restrictive lung disease, edematous skin, joint contractures, digital ulcers, and muscle weakness.
