摘要

Efforts to find new bradykinin B(1) receptor antagonists identified 2-aminobenzimidazole as a novel core. Subsequent transformation into five-membered diaminoheterocycle derivatives and their synthesis and SAR is described. This resulted in compounds with low nanomolar activity.Copyright (c) 2009 Elsevier Ltd. All rights reserved.
