Thiodigalactoside (TDG) 是一种具有口服活性的，有效的半乳凝素 (GAL) 抑制剂，对于 GAL-1 和 GAL-3 的 Kd 值分别为 24 μM，49 μM。Thiodigalactoside 是一种不可代谢的二糖，具有抗炎和抗癌活性。Thiodigalactoside 可显着降低饮食诱发的肥胖大鼠的体重增加。 D-Galactopyranosyl-β- D-thiogalactopyranoside (Thiodigalactoside) is a compound belonging to the dihexoses (disaccharides containing two hexose carbohydrates). Thiodigalactoside is known to target galectin-1, heat-labile enterotoxin b chain, neurocan core protein, and lactose permease.|D-Galactopyranosyl-β- D-thiogalactopyranoside is often used to study galectins, a family of glycan-binding lectins with diverse regulatory roles in physiological processes. Galectins have significant roles in inflammation and cancer. Thiodigalactoside is a diglycan that binds galectins-1, -3, -8, and -9 with Kd values between 24 and 78 μM. It is used to investigate the roles of these galectins in cell signaling and carcinogenesis.
