Gambogic acid (GA), a natural product, exhibits high potency in inhibiting cancer cell growth through the effective induction of apoptosis. In order to investigate the structure–activity relationships of GA derivatives, 11 oxidized derivatives of GA were synthesized. Some of them showed strong inhibitory effects on HT-29, Bel-7402, BGC-823, A549, and SKOV 3 cell lines. Moreover, in this paper the cellular
藤黄酸(GA)是一种天然产物,通过有效诱导凋亡,在抑制癌细胞生长方面表现出很高的效力。为了研究GA衍生物的结构-活性关系,合成了11种GA的氧化衍生物。其中一些对HT-29,Bel-7402,BGC-823,A549和SKOV 3细胞系显示出强大的抑制作用。此外,在本文中,通过Annexin-V / PI双重染色法和相关凋亡蛋白的表达(39),将细胞生长抑制剂39-羟基-6-甲氧基-藤黄酸甲酯(10)鉴定为HepG2细胞凋亡抑制剂。 Bax和Bcl-2)。化合物10可以作为开发新的抗癌药物的潜在先导化合物。进一步的GA衍生物的SAR研究表明,修饰C-32 / 33或C-37 / 38处的碳-碳双键以及C-39 / C-35处的甲基可以改善抗肿瘤活性。
