The fredericamycin A analogues 5 and 23 were synthesized. A key step is the process of radical spirocyclization, and the diastereoselectivity of this reaction was studied with model compounds. In vitro tests showed that 23 was active against certain cell lines of colon and prostate cancer, while compound 5 was essentially inactive.
合成了腓特烈霉素A类似物5和23。关键步骤是自由基螺环化的过程,并使用模型化合物研究了该反应的非对映选择性。体外测试表明,23对结肠癌和前列腺癌的某些细胞系具有活性,而化合物5本质上无活性。
