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
