explore the active components against gastric cancer from the Tibetan Medicine Corydalis hendersonii Hemsl, which is rich in isoquinoline alkaloids. 14 compounds including 2 previously undescribed natural products were obtained. Interestingly, an new active compound displays potent anti-gastric cancer activity. After accomplishing the total syntheses of the active compound and its derivatives, the anti-gastric
异喹啉生物碱因其独特的结构而显示出显着的抗胃癌作用,越来越受到抗胃癌药物开发的关注。在这项研究中,我们从富含异喹啉生物碱的藏药延胡索中探索了抗胃癌的活性成分。获得了 14 种化合物,包括 2 种先前未描述的天然产物。有趣的是,一种新的活性化合物显示出有效的抗胃癌活性。在完成活性化合物及其衍生物的全合成后,进一步研究了活性化合物的抗胃癌活性。体外实验表明,活性化合物显着减弱增殖能力,引起G2/M期阻滞,抑制细胞迁移和侵袭,诱导细胞凋亡。从机制上讲,该活性化合物可以增加 Bax/Bcl-2 比率,提高细胞质中的细胞色素c,并激活 caspase-9/3,同时使上游 PI3K/Akt/mTOR 信号通路失活。此外,该活性化合物还可以通过抑制拓扑异构酶 I 的活性导致胃癌细胞死亡。更重要的是,该活性化合物的抗胃癌活性在MGC-803异种移植裸鼠体内得到证实。这项工作不仅促进了紫堇的开发利用Hemsl
