liver diseases caused by hepatitis B virus (HBV) are the accepted main cause leading to liver cirrhosis, hepatic fibrosis, and hepatic carcinoma. Sodium taurocholate cotransporting polypeptide (NTCP), a specific membrane receptor of hepatocytes for triggering HBV infection, is a promising target against HBVentry. In this study, pentacyclictriterpenoids (PTs) including glycyrrhetinic acid (GA), oleanolic

The effect of glycyrrhetinic acid (GA) and GA-derivatives towards 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD) was investigated. Novel compounds with modi. cations at positions C-3, C-11 and C-29 of the GA skeleton were prepared. Single crystal X-ray diffraction data of selected substances are reported and discussed.

Synthesis and structure-activity relationship studies of water-soluble β-cyclodextrin-glycyrrhetinic acid conjugates as potential anti-influenza virus agents
Glycyrrhetinic acid (GA) is a major constituent of the herb Glycyrrhiza glabra, and many of its derivatives demonstrate a broad spectrum of antiviral activities. In the current study, 18 water-soluble β-cyclodextrin (CD)-GA conjugates, in which GA was covalently coupled to the primary face of β-CD using 1,2,3-triazole moiety along with varying lengths of linker, were synthesized via copper-catalyzed

As a gasotransmitter, carbonmonoxide can induce tumor cell apoptosis by reversing the Warburg effect. Carbon monoxide-releasing molecules (CORMs) are a promising option for CO administration, but how to deliver the threshold concentration of CO into the tumor tissue remains a challenge. A series of novel targeted CORMs combining glycyrrhetinic acid (GA) derivative conjugates with a lipophilic mitochondriotropic
作为气体递质,一氧化碳可以通过逆转瓦尔堡效应来诱导肿瘤细胞凋亡。一氧化碳释放分子(CORM)是 CO 给药的一个有前途的选择,但如何将阈值浓度的 CO 输送到肿瘤组织中仍然是一个挑战。合成了一系列将甘草次酸 (GA) 衍生物缀合物与亲脂性线粒体三苯基鏻阳离子 (TPP + ) 部分相结合的新型靶向 CORM,并评估了其抗肿瘤活性。其中,复合物2在HepG2细胞中具有优异的抗肿瘤活性,与5-FU相比,其IC 50值为12.18 ± 4.66 μM 。它引起活性氧的产生并降低针对 HepG2 细胞的线粒体膜电位。 Western blot分析显示,复合物2上调Bax蛋白的表达,下调Bcl-2、活化的caspase-3和HO-1的表达。对接研究表明,复合物2可以通过疏水相互作用和氢键与Bcl-2蛋白相互作用。上述结果表明复合物2通过线粒体途径触发细胞凋亡。这些结果表明该复合物可能是有前途的抗癌剂候选者。
