The synthesis and pharmacological activity of isoindolo[1,2-b]quinazolin-12(10H)-ones and isoindolo[2,1-a]benzimidazoles related to batracylin are described. The acute toxicity of batracyclin has been associated with the formation of its N-acetyl metabolite which is a potent inducer of unscheduled DNA synthesis in rat hepatocytes. The desamino derivative and the 8-aza analog of batracylin retained
描述了与batracylin有关的异吲哚并[1,2-b]喹唑啉-12(10H)-one和异吲哚并[2,1-a]苯并咪唑的合成及其药理活性。Batracyclin的急性毒性与其N-乙酰代谢产物的形成有关,N-乙酰代谢产物是大鼠肝细胞中非计划DNA合成的有效诱导剂。batracylin的脱氨基衍生物和8-氮杂类似物保留了抑制拓扑异构酶II的能力,但没有诱导计划外的DNA合成。这些类似物虽然不如batracylin活性强,但对CCRF CEM白血病细胞具有细胞毒性。异吲哚并[2,1-a]苯并咪唑衍生物作为拓扑异构酶II抑制剂是无活性的,并且通常不能表现出可比的抗肿瘤活性或无法诱导计划外的DNA合成。
