In the search of structure–activity relationship studies and to explore the antitumor effect associated with the pyrimidoisoquinolinequinone scaffold, several diversily substituted 8-aminopyrimido[4,5-c]isoquinolinequinones were regioselectively synthesized. Variation in the structure of the nitrogen substituent bonded to the 8-position of the pyrimidoisoquinolinequinone system led to a set of alkylamino-
在寻找结构-活性关系研究和探索与嘧啶异喹啉喹醌骨架有关的抗肿瘤作用时,区域选择性地合成了几种不同取代的8-氨基嘧啶基[4,5- c ]异喹啉喹酮。与嘧啶异喹啉喹酮系统的8位键合的氮取代基的结构变化导致形成一组烷基氨基,苯基氨基和烷基苯基氨基衍生物。在体外评估了氨基醌衍生物的细胞毒性活性使用MTT比色法针对一种正常细胞系(MRC-5肺成纤维细胞)和四种人类癌细胞系(AGS人胃腺癌; SK-MES-1人肺癌细胞和J82人膀胱癌; HL-60人白血病) )在72小时的药物暴露试验中。在该系列中,五种化合物对AGS人胃腺癌和人肺癌细胞表现出令人感兴趣的抗肿瘤活性。SAR研究表明,醌环中的氮取代基和6位上的甲基在抗肿瘤活性中均起着关键作用。
