quinazoline ring is possible and often beneficiary for a high level of cytotoxicity. We have also showed that a carbazole or an indole nucleus are very effective as B-rings in this series, leading to anti-cancer drugs 1 having a sub-nanomolar level of cytotoxicity (1a: IC50 = 70 pM against HCT116 cells). 1a also display a high level of cytotoxicity against four other human cancer cells and inhibited tubulin assembly
描述了一系列N,N-双-杂环-甲基胺1的合成和评价,其为异氮杂紫红素类似物。已证明用喹啉或喹唑啉环代替CA-4,iso CA-4和异氮杂紫宁中存在的3,4,5-三甲氧基苯基A-环是可能的,并且对于高水平的细胞毒性通常是有益的。我们还表明,咔唑或吲哚核作为该系列中的B环非常有效,导致抗癌药物1的细胞毒性水平低于纳摩尔水平(1a:IC 50 = 70 pM,针对HCT116细胞)。1a还显示出对其他四种人类癌细胞的高细胞毒性,并以微摩尔水平抑制了微管蛋白的组装。此外,浓度为5 nM时,1a使细胞周期停滞在细胞周期的G2 / M期,并诱导HCT116细胞凋亡。还显示在几个小时后,浓度为10 nM的1a完全破坏了Matrigel上的内皮网络形成。
