The invention provides compounds for inhibiting glycosidases, prodrugs of the compounds, and pharmaceutical compositions including the compounds or prodrugs of the compounds. The invention also provides methods of treating diseases and disorders related to deficiency or overexpression of O-GlcNAcase, accumulation or deficiency of O-GlcNAc.

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。
