chloro-substituted [(aminoalkyl)amino]anthraquinones were synthesized and evaluated for their antineoplastic and cytotoxic activity. Treatment of 5,8-dichloroquinizarin with substituted amines in pyridine resulted in the replacement of one halogen atom by the amino group to yield mainly 1-chloro-5,8-dihydroxy-4-(substituted amino)anthraquinones. On the other hand, reaction between the dichloroquinizarin and
合成了许多氯取代的[(氨基烷基)氨基]蒽醌,并评估了它们的抗肿瘤和细胞毒性活性。用吡啶中的取代胺处理5,8-二氯喹啉,导致一个卤素原子被氨基取代,主要产生1-氯-5,8-二羟基-4-(取代的氨基)蒽醌。另一方面,二氯喹嗪林和丁醇中的胺之间的反应主要产生1,4-二氯-5-羟基-8-(取代的氨基)蒽醌。通过常规方法,用各种胺置换适当的蒽醌衍生物的氯,硝基或甲苯磺酰基官能团,制得该系列的其他化合物。1,4-二氯-5-羟基-8-[[[2-[((2-羟基乙基)氨基]乙基]氨基]蒽醌(6b)对P388白血病具有最高的抑制活性。它对B16黑色素瘤和体外L1210筛选的抑制作用也很重要。其他几种被氯和羟基取代的氨基蒽醌(5a,5b和6a)在体内和体外对P388和L1210也表现出明显的活性。结构活性关系检查表明,羟基可能有助于某些氯氨基蒽醌的生物活性结合,[2-[((2-羟乙基)氨基]乙基]氨基侧链似乎是比其他取代基更好的取代基。氨基侧链。
