Antiinflammatory and/or analgesic activities have been ascribed to compounds containing the 4(3H)-quinazolinone or pyrazole moiety. Continuation to the previous work in the field of the synthesis of non-steroidal antiinflammatory 4(3H)-quinazolinones, the present investigation deals with the synthesis of new compounds having the pyrazole or pyrazoline and 4(3H)-quinazolinone moieties in one molecule
抗炎和/或镇痛活性归因于含有 4 (3H)-喹唑啉酮或吡唑部分的化合物。继续先前在非甾体抗炎 4 (3H) -喹唑啉酮合成领域的工作,本研究涉及在一个分子中具有吡唑或吡唑啉和 4 (3H) -喹唑啉酮部分的新化合物的合成,希望这种组合可以提高它们的抗炎活性。α, β-不饱和酮用水合肼处理时可环化为相应的吡唑啉衍生物,而当使用芳基肼时,则形成吡唑衍生物。
