  Structure–activity relationships for 1-alkyl-3-(1-naphthoyl)indoles at the cannabinoid CB1 and CB2 receptors: steric and electronic effects of naphthoyl substituents. New highly selective CB2 receptor agonists

  摘要：

  In an effort to improve indole-based CB2 cannabinoid receptor ligands and also to develop SAR for both the CB1 and CB2 receptors, 47 indole derivatives were prepared and their CB1 and CB2 receptor affinities were determined. The indole derivatives include 1-propyl- and 1-pentyl-3-(1-naphthoyl)indoles both with and without a 2-methyl substituent. Naphthoyl substituents include 4- and 7-alkyl groups as well as 2-, 4-, 6-, 7-methoxy and 4-ethoxy groups. The effects of these substituents on receptor affinities are discussed and structure-activity relationships are presented. In the course of this work three new highly selective CB2 receptor agonists were identified, 1-propyl-3-(4-methyl-1-naphthoylindole (JWH-120), 1-propyl-2-methyl-3-(6-methoxy-1-naphthoylindole (JWH-151), and 1-pentyl-3-(2-methoxy-1-naphthoylindole (JWH-267). GTPgammaS assays indicated that JWH-151 is a full agonist at CB2, while JWH-120 and JWH-267 are partial agonists. Molecular modeling and receptor docking studies were carried out on a set of 3-(4-propyl-1-naphthoyl)indoles, a set of 3-(6-methoxy-1-naphthoyl)indoles and the pair of N-pentyl-3-(2-methoxy-1-naphthoyl)indoles. Docking studies indicated that the CB1 receptor affinities of these compounds were consistent with their aromatic stacking interactions in the aromatic microdomain of the CB1 receptor.

  日期：——

  A simple and efficient 3-acylation of indoles under microwave-heated and solvent-free conditions is developed. This general procedure uses neutral Al2O3 as a new, green and reusable catalyst giving good to high yields within short reaction times. Utilizing such an environmentally-benign methodology, a variety of indoles bearing electron-releasing or electron-withdrawing groups were conveniently acylated.

  Cannabinoid analogues that exhibit specificity for the CB 2 cannabinoid receptor are provided. The analogues are 1-methoxy-, 1-deoxy-11-hydroxy- and 11-hydroxy-1-methoxy-Δ 8 -tetrahydrocannabinols and 1-alkyl-3(1-naphthoyl)indoles. The compounds are useful for the treatment of pain (especially pain resulting from inflammation) and cancer (especially glioma tumors).
