生物活性
Fagomine 是一种温和的糖苷酶 (glycosidase) 抑制剂，Fagomine 作用于 Amyloglucosidase (A.niger)，β-Glucosidase (bovine) 和 Isomaltase (yeast)，Ki 分别为 4.8 μM，39 μM 和 70 μM。
体外研究
Fagomine (D-fagomine) is an iminosugar that has been shown to selectively agglutinate Enterobacteriales in vitro. Fagomine selectively agglutinates fimbriated enterobacteria (e.g., E.coli ) and inhibits their adhesion to the intestinal mucosa; the reason for this is probably related to its structural similarity with lectin-binding saccharides (e.g., mannose). Fagomine is capable of altering this effect of high-fat high-sucrose diet (HFHS) on the proportion of Enterobacteriales and E.coli .
体内研究
Fagomine (D-fagomine) is a natural iminosugar that counteracts the short-term effects of a high-energy-dense diet on body weight, fasting blood glucose levels and the proportion of gut Enterobacteriales. Compare to the standard group, rats fed high-fat high-sucrose diet (HFHS) with Fagomine (D-fagomine) gain significantly less weight (15.3%) than those fed HFHS (20.9%).
