Certain iminonaphtho[2,3-b]furanderivatives were synthesized from their respective carbonyl precursors in the regiospecific and the stereospecific manners. These compounds were evaluated for their antiproliferative effects against four human carcinoma cells (MCF7, NCI-H460, SF-268, and K562) and the normal fibroblast cell line (Detroit 551). Among them, (Z)-4-(hydroxyimino)naphtho[2,3-b]furan-9(4H)-one
从它们各自的羰基前体以区域特异性和立体特异性方式合成了某些亚氨基萘[2,3- b ]呋喃衍生物。评估了这些化合物对四种人类癌细胞(MCF7,NCI-H460,SF-268和K562)和正常成纤维细胞系(底特律551)的抗增殖作用。其中,(Z)-4-(羟基亚氨基)萘并[2,3 - b ]呋喃-9(4H)-一(8)和(Z)-4-甲氧基-亚氨基萘并[2,3 - b ]呋喃-9(4 H)-一(9)表示GI 50值分别对K562细胞的生长为0.82和0.60μM,并且对正常的成纤维细胞底特律551没有活性。K562细胞对8和9的选择性指数(SI)分别为> 121.95和> 166.67,具有可比性对柔红霉素(SI = 239)较喜树碱(SI = 16.5)更有利。对K562的细胞周期分析表明,这些化合物将细胞周期阻滞在G2 / M期。形态学评估和DNA片段化分析表明9诱导的K562细胞凋亡。凋亡诱导
