synthesized a novel series of 3,9-substituted α-carboline derivatives and evaluated the new compounds for antiproliferactive effects. Structure activity relationships revealed that a COOCH3 or CH2OH group at position-3 and substituted benzyl group at position-9 of the α-carboline nucleus were crucial for maximal activity. The most active compound, 11, showed high levels of cytotoxicity against HL-60, COLO
在我们继续关注1-苄基-3-(5-羟甲基-2-呋喃基)吲唑(YC-1)类似物的过程中,我们合成了一系列新的3,9-取代的α-咔啉衍生物,并评估了这些新化合物的抗增殖活性效果。结构活性关系表明,α-咔啉核第3位的COOCH 3或CH 2 OH基团和第9位的取代苄基是最大活性的关键。活性最高的化合物11对HL-60,COLO 205,Hep 3B和H460细胞表现出高水平的细胞毒性,IC 50值分别为0.3、0.49、0.7和0.8μM。化合物11的作用细胞周期分布的变化证明了G2 / M在COLO 205细胞中的停滞。此外,机理研究表明,化合物11通过激活COLO 205细胞中的死亡受体和线粒体依赖性凋亡信号通路来诱导凋亡。新的3,9-取代的α-咔啉衍生物表现出优异的抗增殖活性,化合物11可以用作有希望的促细胞凋亡剂,用于将来开发新的抗肿瘤剂。
