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.
