LY-320135 is a substituted benzofuran which is structurally distinct from the aminoalkylindole and pyrazole type cannabinoid antagonists, AM630 and SR141716A, respectively. LY-320135 is a potent and selective canniboid CB1 receptor antagonist/inverse agonist. LY-320135 is selective (~70 fold) over canniboid CB2 receptors. LY-320135 is widely used in research, particularly for elucidating the mechanisms by which many CB1 antagonists act as inverse agonists at higher doses. LY-320135 shows weak binding to both 5-HT2 (Ki = 6.4 uM) and muscarinic receptors (Ki = 2.1 uM).
