Conformationally restricted congeners of hypotensive and platelet aggregation inhibitors: 6-aryl-5-methyl-4,5-dihydro-3(2H)-pyridazinones derived from 5H-indeno[1,2-c]pyridazine

A number of 7-amino and 7-acylamino substituted 4,4a-dihydro-5H-indeno[1,2-c]pyridazin-3-ones have been synthesized as rigid congeners of hypotensive 6-aryl-5-methyl-4,5-dihydro-3(2H)-pyridazinones and tested as antihypertensive, antithrombotic, antiulcer, and antiinflammatory agents. Unlike the pre...
