To explore the acceptor regioselectivity of OleD-catalyzed glucosylation, the products of OleD-catalyzed reactions with six structurally diverse acceptors flavones— (daidzein), isoflavones (flavopiridol), stilbenes (resveratrol), indole alkaloids (10-hydroxycamptothecin), and steroids (2-methoxyestradiol)—were determined. This study highlights the first synthesis of flavopiridol and 2-methoxyestradiol
为了探索 OleD 催化葡萄糖基化的受体区域选择性,OleD 催化反应的产物与六种结构不同的受体黄酮(黄豆苷原)、异黄酮(flavopiridol)、芪(白藜芦醇)、吲哚生物碱(10-羟基喜树碱(10-羟基喜树碱)、 2-甲氧基雌二醇)-测定。该研究重点介绍了黄酮醇和 2-甲氧基雌二醇糖苷的首次合成,并证实了 OleD 对芳香族和脂肪族亲核试剂进行葡萄糖基化的能力。在所有情况下,分子动力学模拟与确定的产品分布一致,并表明开发虚拟筛选模型以识别其他 OleD 底物的潜力。
