摘要

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 were also discussed in the present paper.
