N1-arylsulfonyl-3-(1,2,3,6-tetrahydropyridin-4-yl)-1H-indole derivatives are potent and selective 5-HT6 receptor antagonists.

摘要

A series of N(1)-arylsulfonyl-3-(1,2,3,6-tetrahydropyridin-4-yl)indole derivatives was designed and synthesized. These compounds were shown to have high affinity for the 5-HT(6) receptor. Two analogs, 4-[3-(1,2,3,6-tetrahydropyridin-4-yl)-1H-indole-1-sulfonyl]-phenylamine 15g and 4-[3-(1,2,3,6-tetrahydropyridin-4-yl)-5-methoxy-1H-indole-1-sulfonyl]-phen ylamine 15y, had 0.4 and 3.0 nM affinity, respectively, and antagonized the production of adenylate cyclase at sub-nanomolar concentrations.
