Product Overview

Cannabinoid receptors (CB) are members of the class A G protein-coupled receptor (GPCR) family. CB1 and CB2 display about 44% amino acid sequence homology (1,2). There are more than 100 different plant-based cannabinoids with different affinities to cannabinoid receptors. The psychoactive drug 9-tetrahydrocannabinol (THC) is the most prominent one. CB1 receptors are mainly expressed in the brain (cerebral cortex, hippocampus, basal ganglia, and cerebellum) as well as peripheral tissues including leukocytes, spleen, tonsils, thymus, heart, and vasculature (3,4). They promote psychotropic and behavioral effects of cannabinoids. Whereas CB2 receptors are expressed in variety of systems including central nervous system (CNSs), cardiovascular system, respiratory system, bone, gastrointestinal system, liver and the reproductive system (5-7). CB2 receptors are attractive target for development for immune-modulating agents, pain management, osteoporosis, and the treatment of liver diseases (8-10).
