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 (IC50 = 0.4 nM) and 15e (IC50 = 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 reference drug losartan in RHRs, and meanwhile, 14f has no significant impact on heart rate. The interesting activities of these compounds may make them promising candidates as antihypertensive agents. (C) 2013 Elsevier Ltd. All rights reserved.
