Description

Cannabinoid compounds and their use in treating parkinson's disease

Technical Field

The invention relates to the field of biological medicines, and in particular relates to application of cannabis whole-lineage oil in treatment of Parkinson.

Background

Parkinson's Disease (PD) is a degenerative disorder of the central nervous system, the second most common neurodegenerative disease after alzheimer's disease. PD is generally classified as a movement disorder, primarily characterized by resting tremor, stiffness, bradykinesia, and postural instability, with resting tremor being the most common and often the earliest developing symptom, with dementia usually occurring in the later stages of the disease. Motor symptoms of PD arise from the death of dopamine-producing cells in the substantia nigra (a region of the midbrain), the cause of which is unknown. Although dopamine is effective in treating motor symptoms in the early stages of the disease, dopamine's efficacy is lost in the later stages of the disease and its long-term use can lead to motor complications.

Cannabis is belonging to Cannabis family and genus Cannabis, and has important agricultural and medicinal value. Cannabinoids are a class of chemical substances known to activate cannabinoid receptors in cells, and pharmacological studies have shown that the main active ingredient in cannabis is a cannabinoid (cannabinoids). The phyto-cannabinoid is a cannabinoid extracted from cannabis sativa plant, and can also be synthesized artificially. At least 85 different cannabinoids can be isolated from the cannabis plant, differing in their structure depending on where the precursor Cannabinoid (CBG) is cyclized. The main cannabinoids in the hemp plant include Tetrahydrocannabinol (THC), Cannabinol (CBN), Cannabidiol (CBD), Cannabidivarin (CBDV), Tetrahydrocannabidivarin (THCV) and Cannabigerol (CBG), wherein the three components account for more than 90% of the cannabinoids.

It is well known that different cannabinoids have different properties. For example, CBDV is a non-addictive component in marijuana, can block the influence of the main addictive substance THC in marijuana on the human nervous system, and has pharmacological activity of treating epilepsy, neuropathic pain, arthritis, influenza and the like. Thus, it should be appreciated that while cannabinoids are all produced in different lines of the cannabis plant, it cannot be assumed that they all have the same properties. Because of this, research is constantly ongoing on numerous extracts in cannabis, and new breakthroughs are continuing. For example, european patent EP2726069 discloses cannabinoids for use in the prevention or treatment of neurodegenerative diseases or disorders, wherein preferably the cannabinoids are cannabichromene (CBC), Cannabinoxide (CBDV) and/or cannabinoid acid (CBDVA) and the neurodegenerative disease or disorder to be prevented or treated is alzheimer's disease. British patent GB2432312 discloses that cannabis plant extract cannabinoids are more effective in preventing neurodegeneration than purified compounds, in particular the extract cannabinoids Tetrahydrocannabinoids (THC) or Cannabinoids (CBD). However, there are few reports of THCV and less reports of its use in treating parkinson's disease in the currently disclosed series of cannabinoid pharmaceutical applications.
