Abstract:
A new class of benzimidazole-5-sulfonamides has been identified as nonpeptide luteinizing hormone-releasing hormone (LHRH) antagonists. Initial structure-activity relationships are presented resulting in compounds 19 and 28 with submicromolar dual functional activity on human and rat receptors.
