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。
Semisynthetic 18β-glycyrrhetinic acid (GA) analogues bearing 1-en-2-cyano-3-oxo substitution on ring A have enhanced antitumor effects with reduced levels of HDAC3 and HDAC6 proteins. Aiming to inhibit both HDAC protein and activity, we developed a hybrid molecule by tethering active GA analogue methyl 2-cyano-3,11-dioxo-18β-olean-1,12-dien-30-oate (CDODA-Me) and Vorinostat (SAHA). We tested the proper
antitumor activity of the batch of (R)-lipoic acidderivatives. And among them, only compound 13a exhibited moderate anti-proliferation activity against both K562 and K562/ADR cell lines, while it exhibited no anti-proliferation activity against BEL-7402 and L-O2 cell lines. Therefore, it suggested that it was not suitable for hybridization of hydrogen sulfide donors attached to oleanolic acid, ursolic
