A series of benzimidazoles (4) was synthesized and evaluated in vitro as potent and selective NPY Y1 receptor antagonists. Substitution of the piperidine nitrogen of 4 with appropriate R groups resulted in compounds with more than 80-fold higher affinity at the Y1 receptor compared to the parent compound 5 (R = H). The most potent benzimidazole in this series was 21 (K-i = 0.052 nM). (C) 1999 Elsevier Science Ltd. All rights reserved.
