4(3H)-Quinazolinone and pyrazole derivatives have been shown to have analgesic and anti-inflammatory properties. In this study, 14 new 3-methyl-4(3H)quinazolinone derivatives bearing 2-[1'-phenyl-3'-(substituted-phenyl)-2'-propenylidene]hydrazino or 2[5'-(substituted phenyl)-3'-phenyl-2'-pyrazolin-1'-yl] groups have been synthesized with the aim of obtaining new analgesic and anti-inflammatory leads. The structures were elucidated by means of UV, IR, H-1-NMR, C-13-NMR, mass spectroscopy, and elemental analysis data. The anti-inflammatory activities of the synthesized compounds were determined by carrageenan-induced hind paw edema test in mice. All the compounds showed statistically significant effects. For analgesic activity assessment, p-benzoquinone-induced writhing test was applied in mice. The results obtained were in accordance with the anti-inflammatory activity tests.
