Using matrine (1) as the lead compound, a series of new 14-(N-substituted-2-pyrrolemethylene) matrine and 14-(N-substituted-indolemethylene) matrine derivatives was designed and synthesized for their potential application as anticancer agents. The structure of these compounds was characterized by 1H NMR, 13C NMR and ESI-MS spectral analyses. The target compounds were evaluated for their in vitro cytotoxicity
以苦参碱(1)为先导化合物,设计合成了一系列新的14-(N-取代-2-吡咯亚甲基)苦参碱和14-(N-取代-吲哚亚甲基)苦参碱衍生物,作为其潜在的抗癌剂。这些化合物的结构通过1 H NMR,13 C NMR和ESI-MS光谱分析进行表征。评价目标化合物对三种人类癌细胞系(SMMC-7721,A549和CNE2)的体外细胞毒性。结果显示,化合物A6和B21对具有IC 50的三种癌细胞系表现出最显着的抗癌活性值在3.42-8.05μM范围内,显示出比母体化合物(苦参碱)和阳性对照顺铂更好的活性。此外,膜联蛋白V-FITC / PI双重染色试验表明,化合物A6和B21可以剂量依赖性显着诱导SMMC-7721和CNE2细胞的凋亡。细胞周期分析还表明,化合物A6可导致SMMC-7721和CNE2细胞在G2 / M期的细胞周期停滞。
