摘要:
Nicotinamides of benzyl-substituted 4-aminopiperidines and their seven-membered analogs of generic structure 2 and 20 have been discovered as potent and selective SST5 antagonists. The activity (K-i) ranges from 2.4 to 436 nM. Most compounds exhibit decent physicochemical properties and follow a clear SAR pattern. Interestingly enough, the receptor is strongly enantiodiscriminating and binds in the amino-azepaneseries only the (R)-enantiomer. (C) 2010 Elsevier Ltd. All rights reserved.
