inhibitors than natural ligand fragments. Here, we describe the synthesis and evaluation of 3-C-methyl-gulopyranoside derivatives and their evaluation as galectin inhibitors. Methyl 3-deoxy-3-C-(hydroxymethyl)-β-d-gulopyranoside showed 7-fold better affinity for galectin-1 than the natural monosaccharide fragment analog methyl β-d-galactopyranoside, as well as a high selectivity over galectin-2, 3, 4, 7,
半乳凝素是参与不同半乳凝素亚型特异性的炎症和肿瘤促进过程的半乳糖苷识别蛋白家族,可促进抑制剂的发展,该抑制剂比天然配体片段更具选择性。在这里,我们描述了3 C-甲基-甲基吡喃果糖苷衍生物的合成和评估及其作为半乳凝素抑制剂的评估。与天然单糖片段类似物甲基β-d-吡喃半乳糖苷相比,甲基3-脱氧-3-C-(羟甲基)-β-d-吡喃葡糖苷对半乳凝素1的亲和力高7倍,并且对半乳凝素-β的选择性高。 2、3、4、7、8和9。将3-C-羟甲基衍生为酰胺可得到具有改进的选择性和亲和力的古洛糖苷。甲基3-脱氧-3-C-(甲基-2,3,4,5,
