Selective monofluorination of the α‐glycosidase inhibitor and antidiabetic agent miglitol at positions C(2′) or C(6) creates competitive inhibitors of glycosidases. Introducing a fluorine substituent at position C(6) results in a reduced binding to the enzyme whereas fluorination at C(2′) produces an inhibitor with an activity four times higher than the parent compound. This compound is selective for
α-糖苷酶抑制剂和抗糖尿病药物米格列醇在 C(2') 或 C(6) 位的选择性单氟化作用产生糖苷酶的竞争性抑制剂。在 C (6) 位引入氟取代基导致与酶的结合降低,而 C (2') 处的氟化产生活性比母体化合物高四倍的抑制剂。该化合物对来自生咖啡豆的 α-半乳糖苷酶具有选择性。它针对一组人类细胞系的筛选显示出低细胞毒性,因此,使该化合物成为进一步临床研究的有趣候选者。
