Synthesis, biological evaluation and structure–activity relationships of glycyrrhetinic acid derivatives as novel anti-hepatitis B virus agents
摘要:
Fifty-seven derivatives of glycyrrhetinic acid (GA) were synthesized, and their anti-hepatitis B virus (HBV) activity was evaluated in HepG 2.2.15 cells. Among them, sixteen compounds showed greater anti-HBV activity than GA, especially, compounds 29, 32, 35, 41 exhibited significantly inhibitory activities against HBV DNA replication with IC50 values of 5.71, 5.36, 8.90 and 9.08 mu M, respectively. The structure-activity relationships (SARs) of GA derivatives were discussed for exploring novel anti-HBV agents. (C) 2012 Elsevier Ltd. All rights reserved.
get “simple” derivatives, for example esters, amides and a nitrile. The influence of these changes on the cytotoxic activity is noteworthy and was determined by a colorimetric sulphorhodamine B test using 7 human tumor cell lines and mouse embryonic fibroblasts (NIH3T3) for comparison. A Trypan blue test as well as an acridine orange/ethidium bromide test was used to discover the ability of the compounds
甘草根的提取物已用于传统和民间医学,以治疗多种疾病。这些提取物的主要成分是甘草酸。它的苷元甘草次酸具有许多生物活性,其中包括对肿瘤细胞的明显细胞毒性。在这项研究中,我们改变了 C-30 位的甘草次酸以获得“简单”的衍生物,例如酯、酰胺和腈。这些变化对细胞毒活性的影响是值得注意的,并且是通过使用 7 种人类肿瘤细胞系和小鼠胚胎成纤维细胞 (NIH3T3) 进行比色的磺胺罗丹明 B 测试来确定的。台盼蓝试验以及吖啶橙/溴化乙锭试验用于发现化合物诱导细胞凋亡的能力。
