O-1821 is a cannabidiol analog with close structural similarity to O-1918 which is a selective antagonist of abnormal cannabidiol at the non-CB1/CB2 endothelial receptor.2 O-1918 does not bind to CB1 or CB2 receptors at concentrations up to 30 µM and inhibits the vasorelaxant effects of abnormal cannabidiol in vitro and in whole animals.2 The biological activity of O-1821 has not been reported.
