Design, synthesis and biological evaluation of 6-substituted aminocarbonyl benzimidazole derivatives as nonpeptidic angiotensin II AT1 receptor antagonists
aminocarbonyl benzimidazole derivatives were designed and synthesized as nonpeptidic angiotensinIIAT1 receptor antagonists. The preliminary pharmacological evaluation revealed nanomolar AT1 receptor bindingaffinity and good AT1 receptor selectivity over AT2 receptor for all compounds of the series, a potentantagonistic activity in isolated rabbit aortic strip functional assay for compounds 6b, 6d and
设计并合成了一系列6-取代的氨基羰基苯并咪唑衍生物,作为非肽类血管紧张素II AT 1受体拮抗剂。初步药理评估显示,该系列所有化合物均具有纳摩尔AT 1受体结合亲和力和优于AT 2受体的良好AT 1受体选择性,并且在分离的兔主动脉带功能测定中还显示了对化合物6b,6d和6i的强拮抗活性。此外,对自发性高血压大鼠的评估和初步毒性评估表明,化合物6i是口服活性AT 1 低毒的受体拮抗剂。
