Two series of novel 2-substituted-4-amino-6-halogenquinolines 8a–l and 13a–h were designed, synthesized and evaluated for their antiproliferative activity against H-460, HT-29, HepG2 and SGC-7901 cancer cell lines in vitro. The pharmacological results indicated that most compounds with 2-arylvinyl substituents exhibited good to excellent antiproliferative activity. Among them, compound 8e was a considered promising lead for further structural modifications with IC50 values of 0.03 μM, 0.55 μM, 0.33 μM and 1.24 μM, which was 2.5- to 186-fold more active than gefitinib and compound 1.
研究人员设计、合成了两个系列的新型 2-取代-4-氨基-6-卤代喹啉类化合物 8a-l 和 13a-h,并在体外评估了它们对 H-460、HT-29、HepG2 和 SGC-7901 癌细胞株的抗增殖活性。药理结果表明,大多数具有 2-芳基乙烯基取代基的化合物都表现出良好至卓越的抗增殖活性。其中,化合物 8e 的 IC50 值分别为 0.03 μM、0.55 μM、0.33 μM 和 1.24 μM,比吉非替尼和化合物 1 的活性高出 2.5 至 186 倍,被认为是有希望进一步进行结构改造的先导化合物。
