two series of indenoisoquinoline prodrugs, and it also reveals how substituents on the O-2 and O-3 positions of the A ring, which are next to the cleaved DNA strand in the drug-DNA-Top1 ternary cleavage complex, affect Top1 inhibitory activity and cytotoxicity. Many of the indenoisoquinoline prodrugs were very potent antiproliferative agents with GI50 values below 10 nM in a variety of human cancer cell
在临床试验中,茚并异喹啉拓扑异构酶I(Top1)抑制剂是一类具有两种化合物的新型抗癌药。Indotecan(LMP400)的最新代谢研究导致发现了具有生物活性的2-羟基化类似物和3-羟基化代谢物,从而为制备这两种化合物的各种潜在酯前药提供了战略上重要的位置。当前的研究详述了两个系列的茚并异喹啉前药的设计和合成,并且还揭示了A环O-2和O-3位置上与药物DNA-中裂解的DNA链相邻的取代基是如何产生的。 Top1三元裂解复合物,影响Top1的抑制活性和细胞毒性。许多茚并异喹啉前药是具有GI 50的强效抗增殖药 在各种人类癌细胞系中,该值低于10 nM。
