In this study, we have explored the prevention of gastric side effects such as gastric lesions and bleeding while maintaining the high analgesic and anti-inflammatory activities by the derivatization of the carboxylate moiety into amides in
Fourty-three new benzoxazolinone derivatives having a piperazinomethyl group at the third position of the ring were synthesized by using appropriate benzoxazolinones and 4-substituted piperazines via a Mannich reaction. The structures of the compounds were elucidated by spectral data and
Twelve new 3-[2-(2- and/or 4-pyridyl)ethyl]benzoxazolinone derivatives have been synthesized by reacting 2- and/or 4-vinylpyridine and appropriate benzoxazolinones. Their chemical structures have been proven by IR, 1H-NMR and elemental analysis. Analgesic activities of these compounds were
Twenty-two new 3-[2-(2-and/or 4-pyridyl)ethyl]benzoxazolinone and oxazolo[4,5-b]pyridin-2-one derivatives have been synthesized by reacting 2- and/or 4-vinylpyridine and appropriate benzoxazolinones and oxazolo[4,5-b]pyridine-2-one. Their chemical structures have been proven by IR. 1H-NMR, 13C-NMR,
