Indolylpiperidine derivatives as potent and selective α1B adrenoceptor antagonists
摘要:
series of novel indolylpiperidine derivatives were synthesized, and their pharmacological profiles were assessed at rat alpha(1A) and alpha(1B) adrenoceptors through in vitro binding studies. Compound 12 (2-(3-(4-(6-fluoro-1H-indol-3-yl)piperidin-1-yl)propyl)-1,2,3,4-tetrahydroisoquinoline) was a potent alpha(1B) adrenoceptor antagonist (K-i = 0.61 nM) and was about 40-fold more selective for the alpha(1B) adrenoceptor than for the alpha(1A) adrenoceptor. In addition, useful structure-activity relationship information was acquired for further improving selectivity for the alpha(1B) adrenoceptor. (C) 2015 Elsevier Ltd. All rights reserved.
