Design and synthesis of 3-(4-ethylphenyl)-2-substituted amino-3H-quinazolin-4-ones as a novel class of analgesic and anti-inflammatory agents.

A new series of 3-(4-ethylphenyl)-2-substituted amino-3H-quinazolin-4-ones were synthesized by reacting the amino group of 2-hydrazino-3-(4-ethylphenyl)-3H-quinazolin-4-one from 4-ethyl aniline with a variety of aldehydes and ketones. The title compounds were investigated for analgesic, anti-inflammatory and ulcerogenic index activities. The compound 2-(N'-3-pentylidene-hydrazino)-3-(4-ethylphenyl)-3H-quinazolin-4-one (AS2) emerged as the most active compound of the series and was moderately more potent than the reference standard diclofenac sodium. Interestingly the test compounds showed only mild ulcerogenic potential when compared to aspirin.[1]
