This study discloses a general and convergent route for the regio- and stereospecific construction of the C5 glycosyl angucycline framework of mayamycin. C-Glycosidation, dearomatization, and Hauser annulation are the key steps. The synthetic analogues show cytotoxicity against different human cancer cell lines with IC50 values between 16.4 and 1.2 μM.
这项研究公开了玛雅霉素C5糖基安古环素骨架的区域和立体特异性构建的通用途径。C-糖基化,脱芳香化和豪瑟环化是关键步骤。合成类似物显示出对不同人类癌细胞系的细胞毒性,IC 50值为16.4至1.2μM。
