the design, synthesis and study of anticancer properties of sulfenylated 2-phenylimidazo[1,2-a]pyridines and their analogues. A set of twenty sulfenylated imidazo[1, 2-a]pyridine derivatives were synthesized. Whereby elusive amendments to the imidazo[1,2-a]pyridine motif confer dramatic changes in functional affinity of a novel action to modulate anticancer activity in seven different human cancer cell
我们在此报告了设计、合成和研究了磺基化 2-苯基咪唑并 [1,2- a ] 吡啶及其类似物的抗癌特性。合成了一组 20 种磺酰化咪唑并 [1, 2- a ] 吡啶衍生物。因此,难以捉摸的咪唑并[1,2- a ]吡啶基序的修正赋予了调节七种不同人类癌细胞系抗癌活性的新作用的功能亲和力的显着变化,即:MDA MB 231(乳腺)、HepG2(肝脏)、 Hela(宫颈)、A549(肺)、U87MG(胶质母细胞瘤)、SKMEL-28(皮肤黑色素瘤)和 DU-145(前列腺)采用 MTT 测定。系列中,化合物4e(萘)、4f(苯乙烯)和4h(thiomethyl) 对人肝癌细胞 HepG2 显示出有效的活性。细胞周期分析结果表明,这些化合物在 G2/M 期阻滞细胞周期并诱导人肝癌细胞 HepG2 凋亡。Hoechst 染色、线粒体膜电位测量 (ΔΨm) 和膜联蛋白 V-FITC 测定进一步证实了这一点。
