Abstract A series of novel 1, 2, 4-triazole bearing 5-substituted biphenyl-2-sulfonamide derivatives were designed and synthesized to develop new angiotensin II subtype 2 (AT 2) receptor agonists as novel antihypertensive candidates. It was found that 14f (IC 50= 0.4 nM) and 15e (IC 50= 5.0 nM) displayed potent AT 2 receptor affinity and selectivity in binding assays. Biological evaluation in vivo suggested that 14f is obviously superior to that of ...
