RCS-4, or 1-pentyl-3-(4-methoxybenzoyl)indole, is a synthetic cannabinoid drug sold under the names SR-19, BTM-4, or Eric-4 (later shortened to E-4), but originally, OBT-199.
==Pharmacology== RCS-4 is a potent cannabinoid receptor agonist, with EC50 values of 146 nM for human CB1 receptors, and 46 nM for human CB2 receptors. All methoxyphenyl regioisomers, and N-butyl homologues of RCS-4 and its regioisomers also display potent agonist activities at CB1 and CB2 receptors.
