O-1918 is a synthetic compound related to cannabidiol , which is an antagonist at two former orphan receptors GPR18 and GPR55 , that appear to be related to the cannabinoid receptors. O-1918 is used in the study of these receptors, which have been found to be targets for a number of endogenous and synthetic cannabinoid compounds, and are thought to be responsible for most of the non-CB1 , non-CB2 mediated effects that have become evident in the course of cannabinoid research.[1] [2] [3] [4] [5]
