cytotoxic natural tetrapeptides with potent antiproliferative, antimitotic, and antiangiogenic activities which might find use in oncology. We herein report the first total synthesis of a stereoisomerically pure oxazole analogue of tubulysin U, which was found to be more cytotoxic than the thiazole-containing natural product. Additionally, we have developed an improved and scalable synthetic route towards
微管溶素是具有强细胞毒性的天然四肽,具有有效的抗增殖、抗有丝分裂和抗血管生成活性,可用于肿瘤学。我们在此报告了微管溶素 U 的立体异构纯恶唑类似物的首次全合成,发现其比含噻唑的天然产物更具细胞毒性。此外,我们开发了一种针对微管溶素 Tup 片段的改进且可扩展的合成路线。
