(from Escherichia coli) lead to the conclusion that the substitution of the C-2 position on the imidazole moiety with cyclohexylethyl or phenylethyl gives the best results (Ki = 2 and 4 nM, respectively, against a β-galactosidase) as compared with the non-substituted azasugar. The synthesis of the imidazolo[1,2-a]-D-xylo-piperidinose substituted with phenylethyl is also reported, as well as its inhibitory
报道了取代的咪唑并[1,2-a]-L-阿拉伯-哌啶糖的合成。取代基是甲基、苯甲基、苯乙基、环己基乙基、吡啶基乙基、哌啶基乙基、苯丙基和羟甲基。所有取代基都与咪唑部分相连。检查新合成化合物对 β-葡萄糖苷酶(来自杏仁)和 β-半乳糖苷酶(来自大肠杆菌)的抑制特性得出的结论是咪唑部分的 C-2 位置被环己基乙基或苯乙基取代与未取代的氮杂糖相比,提供了最好的结果(Ki = 2 和 4 nM,分别针对 β-半乳糖苷酶)。还报道了苯乙基取代的咪唑并[1,2-a]-D-木-哌啶糖的合成,
