provided increased activity against the multidrug-resistant P388/ADR leukemia subline in vivo. Since activity against such resistant tumors is of great clinical significance, a series of acridine-substituted carbamate derivatives were evaluated against both wild-type and ADR/resistant P388 leukemia and the Lewis lung solid tumor in vivo. Structure-activity relationships for all three tumor lines were similar
对一系列与抗白血病药物氨苯磺酸有关的苯胺取代的9-苯胺基cr啶的研究表明,1'-氨基甲酸酯基团在体内对多药耐药的P388 / ADR白血病亚系提供增强的活性。由于针对这种抗药性肿瘤的活性具有重要的临床意义,因此在体内针对野生型和ADR /抗药性P388白血病以及Lewis肺实体瘤评估了一系列of啶取代的氨基甲酸酯衍生物。所有三个肿瘤细胞系的结构活性关系相似,其中3-卤代-5-甲基和3-卤代5-甲氧基化合物被证明是活性最高的。这种取代模式还提供了最高的DNA结合。此类化合物(尤其是3-氯-5-甲基和3-氯-5-甲氧基)对野生型P388和Lewis肺具有体内活性,其活性与先前开发的最佳氨水analogue类似物相当(治愈率超过50%) ,以及P388 / ADR活动。这项工作从根本上完成了amsacrine系列抗肿瘤药的开发。
