Abstract

A number of 6-(substituted phenyl)-2-(4-substituted phenyl-5-thioxo-4,5-dihydro-1H-1,2,4-triazol-3-yl)-4,5-dihydropyridazin-3(2H)-one derivatives were designed and synthesized by a sequence of reactions starting from respective aryl hydrocarbons. The final compounds (4a-4u) were evaluated for antihypertensive activities by non-invasive method using Tail Cuff method. The compounds 4e, 4i and 4k showed appreciable antihypertensive activity comparable with that of standard hydralazine and propranolol.
