A new series of 3-(2-pyridyl)-2-substituted-quinazolin-4(3H)-ones were synthesized by reacting the amino group of 2-hydrazino-3-(2-pyridyl)-quinazolin-4(3H)-one with a variety of aldehydes and ketones. The starting material 2-hydrazino-3-(2-pyridyl)-quinazolin-4(3H)-one was synthesized from 2-aminopyridine. The title compounds were investigated for analgesic, anti-inflammatory and ulcerogenic index activities. While the test compounds exhibited significant activity, compound 2-(1-ethylpropylidene)-hydrazino-3-(2-pyridyl)-quinazolin-4(3H)-one (AS2) showed moderate analgesic activity and compound 2-(1-methylbutylidene)-hydrazino-3-(2-pyridyl)-quinazolin-4(3H)-one (AS3) showed realistic anti-inflammatory activity when compared to the reference standard diclofenac sodium. Interestingly the test compounds showed only mild ulcerogenic side effect when compared to aspirin.
