A series of 4′-[(benzimidazole-1-yl)methyl]biphenyl-2-sulfonamide derivatives (Ia–Il) were synthesized and biologically evaluated. It was found that Ig, the most active compound, antagonized both Ang II AT1 and endothelin ETA receptors (AT1 IC50 = 8.5, ETA IC50 = 8.9 nM), and was more potent than losartan in RHRs with no significant effect on heart rate. The preliminary structure–activity relationships
合成了一系列4'-[[(苯并咪唑-1-基)甲基]联苯-2-磺酰胺衍生物(Ia-11),并对其进行了生物学评估。发现最活跃的化合物Ig拮抗Ang II AT 1和内皮素ET A受体(AT 1 IC 50 = 8.5,ET A IC 50 = 8.9 nM),并且在RHRs中比氯沙坦更有效,没有显着性对心率的影响。初步的结构-活性关系也在本文中进行了讨论。
