In our continuing search for camptothecin (CPT)-derived antitumor drugs, novel 7-substituted CPT derivatives incorporating piperazinyl-sulfonylamidine moieties were designed, synthesized and evaluated for cytotoxicity against five tumor cell lines (A-549, MDA-MB-231, MCF-7, KB, and KB-VIN). All of the derivatives showed promising in vitro cytotoxic activity against the tested tumor cell lines, and
在我们持续寻找喜树碱(CPT)衍生的抗肿瘤药物的过程中,设计,合成并结合了哌嗪基-磺酰胺基部分的新型7-取代CPT衍生物并评估了其对五种肿瘤细胞系(A-549,MDA-MB-231,MCF -7,KB和KB-VIN)。所有衍生物均对被测肿瘤细胞系显示出有希望的体外细胞毒性活性,并且比伊立替康更有效。值得注意的是,大多数化合物对多药耐药(MDR)KB-VIN和亲代KB肿瘤细胞系表现出可比的细胞毒性,而伊立替康完全丧失了对KB-VIN的活性。特别是化合物13r和13p(IC 50 分别为0.38和0.85μM)对MDR KB-VIN细胞系表现出最大的细胞毒性,值得进一步发展成为临床前和临床候选药物来治疗癌症,包括MDR表型。
