pyrimidine ring incorporated into the chromophore system has been obtained in an attempt to provide compounds with diminished peroxidation activity and thus potentially lowered cardiotoxicity. Their synthesis was carried out by the reaction of 6-amino- or 6-hydroxy-7H-benzo[e]perimidin-7-one with a number of alkylamines. Potent activity was demonstrated in vitro against murine L1210 leukemia cells (equipotent
为了提供具有降低的过氧化活性并因此潜在降低的心脏毒性的化合物,已经获得了一类生色团修饰的
蒽二酮,其具有并入生色团系统中的额外的
嘧啶环。它们的合成通过6-
氨基或6-羟基-7H-苯并[e] perimidin-7-1与许多烷基胺的反应进行。在体外对鼠L1210白血病细胞(与
金刚烷酮等效)以及体内P388白血病(%T / C = 130-255)均显示出了强大的活性。我们观察到,苯并perimidines不会刺激自由基的形成,可能是因为它们对
NADH脱氢酶的底物性质很差。
