Twelve 1-phenyl-, 1-thiocarbamoyl- and 1-N-substituted thiocarbamoyl-3-(2-furyl)-5-phenyl/(2-furyl)-2-pyrazoline derivatives were synthesized. The chemical structures of the compounds were proved by IR, (1)H NMR, Mass spectrometric data and microanalyses. The antidepressant activities of the compounds were investigated by Porsolt's behavioural despair (forced swimming) test on albino mice. 1-N-...

In this study, some 4-(1,5-diarylimidazol-2-yl)thioacetyl-1-phenyl-2,3-dimethyl-3-pyrazoline-5-one derivatives were prepared by reacting 4-(2-chloroacetyl)-1-phenyl-2,3-dimethyl-3-pyrazoline-5-one and 2-mercapto-1, 5-diarylimidazole derivatives. The antinociceptive and anticancer activities of the compounds obtained were investigated. It was observed that some of the compounds, 2a, 2d, 2g, and ...
