1H-[1,2,3]-Triazol-1-yl mannosides have been synthesized as inhibitors for the beta-galactoside-binding family of galectin proteins. Easier synthetic access to C1 in mannose, as compared to C3 in galactose, for attachment of affinity-enhancing triazoles rendered a synthetic advantage. The best mannose-derived inhibitor for galectin-9N, 4-benzylaminocarbonyl-1H-[1,2,3]-triazol-1-yl beta-D-mannopyranoside
已经合成了1H- [1,2,3]-三唑-1-基甘露糖苷作为半乳凝素蛋白的β-半乳糖苷结合家族的抑制剂。与半乳糖中的C3相比,甘露糖中C1的合成途径更容易获得亲和力增强的三唑类化合物的合成优势。最佳的半乳糖凝集素-9N的最佳甘露糖衍生抑制剂-4-苄基氨基羰基-1H- [1,2,3]-三唑-1-基β-D-甘露吡喃糖苷,其Kd值为540 microM,与半乳糖苷比较好对应物(Kd = 670 microM)和LacNAc(Kd = 500 microM)。
