analogues with various uncommon sugars showed distinct cytotoxicities and topo I targeting activities. The activity of compounds with 2-deoxyglucose (8 and 9) > compounds with 2,6-deoxyglucose (5 and 6) > compounds with 2,3,6-deoxyglucose (10). Furthermore, the anticancer activity of compounds correlated with their ability to target endogenous topo I. These results suggest that the sugar moiety, especially
已经合成了包含罕见糖和在酰亚胺氮上的取代的瑞贝卡霉素类似物。在结肠癌和白血病细胞中测试了它们的细胞毒性。使用Hela细胞中拓扑异构酶生物测定的体内复合物检查了它们靶向拓扑异构酶I的能力。与糖苷配基1相比,具有各种糖基的修饰化合物显示出更强的细胞毒性和topo I靶向能力。另外,具有多种罕见糖的瑞贝卡霉素类似物显示出独特的细胞毒性和topo I靶向活性。具有2-脱氧葡萄糖的化合物(8和9)>具有2,6-脱氧葡萄糖的化合物(5和6)>具有2,3,6-脱氧葡萄糖的化合物(10)的活性。此外,化合物的抗癌活性与其靶向内源性topo I的能力有关。
