Synthesis and Biological Activity of 3,4-Diaryl-5-[4-(acetylsulfamoyl)phenyl]-4,5-dihydropyrrolo[3,4-c]pyrazol-6(2H)-ones and Their Sodium Salts

Аннотация

3,4-Diaryl-5-[4-(acetylsulfamoyl)phenyl]-4,5-dihydropyrrolo[3,4-c]pyrazol-6(2H)-ones were synthesized be reaction of 5-aryl-4-aroyl-1-[4-(acetylsulfamoyl)phenyl]-3-hydroxy-1H-pyrrole-2(5H)-ones with hydrazine hydrate in glacial acetic acid, and their sodium salts were obtained by treatment with sodium methoxide in methanol–DMF (1: 1). Analgesic and anti-inflammatory activity and acute toxicity of the synthesized compounds were studied.
