N-Alkylation at the ring nitrogen of the D-galactosidase inhibitor 1-deoxygalactonojirimycin with a functionalised C6 alkyl chain followed by modification with different aromatic substituents provided lipophilic 1-deoxygalactonojirimycin derivatives which exhibit inhibitory properties against β-glycosidases from E. coli and Agrobacterium sp. as well as green coffee bean α-galactosidase. In preliminary studies, these compounds also showed potential as chemical chaperones for GM1-gangliosidosis related β-galactosidase mutants.
将D-半乳糖苷酶抑制剂1-去氧半乳糖酮基脲的环氮原子进行N-烷基化,接着用不同芳香基团进行修饰,得到了亲脂性的1-去氧半乳糖酮基脲衍生物,这些衍生物对大肠杆菌和根瘤菌β-葡萄糖苷酶以及绿咖啡豆α-半乳糖苷酶具有抑制作用。在初步研究中,这些化合物还显示出潜力作为GM1-神经节苷脂病相关β-半乳糖苷酶突变体的化学伴侣。
