It suggests that the sugar structure in daunorubicin plays a critical role in determining its anticancer activity. In the compounds with various sugars, the 4'-OH of the sugar is an important determinant for their activity, while the axial-3'-substituent in the sugar interferes with the binding of daunorubicins to DNA. Therefore, 2,6-dideoxy sugars are a better choice for generating biologically active
为了研究糖结构对蒽环类抗癌细胞活性的影响,合成了六种含有不同罕见糖的柔红霉素类似物。通过MTS分析测试了它们对结肠癌细胞的细胞毒性。结果显示,不具有糖部分的糖苷配基对癌细胞的活性比具有各种不常见糖的柔红霉素衍生物低70-100倍。这表明柔红霉素中的糖结构在确定其抗癌活性中起关键作用。在具有各种糖的化合物中,糖的4'-OH是其活性的重要决定因素,而糖中的轴3'-取代基会干扰柔红霉素与DNA的结合。因此,2
