2-Methyl-4(3H)-quinazolines carrying alkyl, cycloalkyl, aralkyl or aryl substituents at N-3 of the quinazoline ring exhibit analgetic, antipyretic and antiinflammatory activities comparable to those of aspirin and phenylbutazone. In our previous work, various 4(3H)-quinazoline derivatives were prepared. The present communication is a continuation of our effort in this field.
在喹唑啉环N-3位带有烷基、环烷基、芳烷基或芳基取代基的2-甲基-4(3H)-喹唑啉显示与阿司匹林和苯丁唑酮相似的镇痛、退热和抗炎活性。在我们以前的工作中,已经制备了各种4(3H)-喹唑啉衍生物。现在的通讯是我们在这个领域努力的延续。
