lung adenocarcinoma cells. Herein, we report the synthesis of thiochondrilline C by N-terminal peptide extension, oxidative disulfide bond formation, and heterocycle installation as key steps. Antiproliferative activities for the prepared natural product and several derivatives against the NCI 60 cancer cell line panel are also described. Derivative 22 was identified as a moderately potent antiproliferative
硫软骨素C(4)先前是从Verrucisispora sp。分离得到的。并且据报道对人肺腺癌细胞具有中等的细胞毒性。在本文中,我们报告了通过N末端肽延伸,氧化二硫键形成和杂环安装作为关键步骤合成硫代软骨素C的过程。还描述了所制备的天然产物和几种衍生物对NCI 60癌细胞系的抗增殖活性。衍生物22被确定为具有白血病(平均GI 50 = 1.8±0.1μM)和结肠(平均GI 50)的中度有效抗增殖剂(50%生长抑制(GI 50)= 0.2–12.2μM)。 = 2.4±0.3μM)细胞是最敏感的。
