The synthesis of two series of derivatives containing the quinazolinone‐4 moiety is described. 3‐Amino‐2(1H)‐thioxo‐4(3H)‐quinazolinone (1) was subjected to reactions with halogenoketones and halogenoaldehydes, leading to the production of the corresponding ketones, aldehydes, Schiff bases, and 6‐oxo‐1,4,5‐thiadiazin[2,3‐b]quinazoline derivatives. Subsequently, 1 was condensed with selected α,β‐unsaturated
描述了包含喹唑啉酮-4 部分的两个系列衍生物的合成。3-氨基-2(1H)-硫代-4(3H)-喹唑啉酮(1)与卤代酮和卤代醛反应,生成相应的酮、醛、席夫碱和6-氧代-1, 4,5-噻二嗪 [2,3-b] 喹唑啉衍生物。随后,1与选定的α,β-不饱和羰基化合物、醛、酮、酰氯和酯缩合。在体液和细胞免疫反应模型中测试了这些化合物的潜在活性。测试表明,这些化合物表现出不同的免疫活性。特别感兴趣的是化合物 19,
