been used in China for decades. A series of novel N-substituted sophoridinic acid derivatives were synthesized and evaluated for their cytotoxicity with 1 as the lead. The structure–activity relationship indicated that introduction of an aliphatic acyl on the nitrogen atom might significantly enhance the anticancer activity. Among the compounds, 6b bearing bromoacetyl side-chain afforded a potential
天然的抗癌药物槐定碱(1)在中国已经使用了数十年。合成了一系列新颖的N-取代的槐定酸衍生物,并以1为先导对其细胞毒性进行了评估。结构-活性关系表明,在氮原子上引入脂族酰基可能会显着增强抗癌活性。在这些化合物中,带有溴乙酰基侧链的6b对四种人类肿瘤细胞系(肝,结肠,乳腺和肺)具有潜在的作用。6b的作用机制是抑制DNA拓扑异构酶I的活性,随后S期停滞,然后导致凋亡性细胞死亡,类似于其亲本1。我们认为6b有希望用于进一步的抗癌研究。
