Ak. Gadad et al., SYNTHESIS, ANALGESIC AND ANTIINFLAMMATORY ACTIVITIES OF SOME 1-ACYL ARACYL-5-AMINOPYRAZOLE DERIVATIVES/, Arzneimittel-Forschung, 46(11), 1996, pp. 1082-1085
A series of 1-acyl/aracyl-3, 4-disubstituted-5-aminopyrazoles (IV) wer
e synthesized by the reaction of 1-acyl/aracylhydrazines (1) with an a
ppropriately substituted ketenedithioacetal (II/III). Compounds IV wer
e tested for their analgesic by rat caudal immersion test and anti-inf
lammatory activity by carrageenin induced edema in rat paw test. 1-Ben
zoyl-3-mercapto-4-carboxamido-5-aminopyrazole (IVk) proved to be the m
ost active compound of the series in both tests.
