Abnormal cannabidiol (abn-cbd) is a synthetic regioisomer of cannabidiol, which unlike most other cannabinoids produces vasodilator effects, lowers blood pressure, and induces cell migration, cell proliferation and mitogen-activated protein kinase activation in microglia, but without producing any psychoactive effects.[1][2] It has been shown that the actions of abnormal cannabidiol are mediated through a site separate from the CB1 and CB2 receptors,[2][3] which responds to abnormal cannabidiol, O-1602, and the endogenous ligands: anandamide (AEA), N-arachidonoyl glycine (NAGly) and N-arachidonoyl L-serine.[2][4][5][6] Multiple lines of evidence support the proposed identification of this novel target in microglia as the previously "orphan" receptor GPR18.[2] Another possible target of abnormal cannabidiol is GPR55, which has also received much attention as a putative cannabinoid receptor,[7][8] although a growing body of evidence points to lysophosphatidylinositol (LPI) as the endogenous ligand for GPR55.[9][10] Further research suggests there are yet more additional cannabinoid receptors.[11][12][13][14]
