摘要:
                                A series of 2-alkylbenzimidazoles bearing a N-phenylpyrrole moiety were synthesized and evaluated as a novel class of AT(1) receptor antagonists. Among them, compounds 10a and 10g inhibited [ I-125] AngII-binding affinity to AT(1) receptor at nanomolar level and potently inhibited the AngII-induced pressor response by oral administration. Moreover, evaluation in spontaneously hypertensive rats showed that 10a is an orally active AT(1) receptor antagonist. (c) 2007 Elsevier Ltd. All rights reserved.
