Description Fagomine (D-Fagomine) is a mild glycosidase inhibitor, an analog of 1-deoxynojirimycin (DNJ) with hypoglycemic activity, and Fagomine reduces intracellular reactive oxygen species (ROS) production and malondialdehyde (MDA) levels.
In vitro Fagomine (D-fagomine), a subamino sugar, exhibits selective agglutination of Escherichia coli in vitro. It selectively aggregates flagellated E. coli, inhibiting their adherence to the intestinal mucosa. This effect may be attributed to its structural similarity with sugar moieties binding to lectins, such as mannose. Fagomine has the ability to alter the impact of a high-fat high-sucrose diet (HFHS) on the ratio of Enterobacteriaceae and Bacteroides in the gut[3].
In vivo Fagomine (D-fagomine), a natural subamino sugar, can counteract the short-term effects of a high-energy density diet on body weight, fasting blood glucose levels, and intestinal Enterobacteriaceae[3]. When compared to the standard group, rats fed a high-fat high-sucrose diet (HFHS) along with D-fagomine exhibited a significantly lower increase in body weight (15.3%), in contrast to rats fed only HFHS (20.9%)[2].
Kinase Assay Lysosomal enzyme activities in cell lysates are determined. Briefly, cells are scraped in ice-cold 0.1% Triton X-100 in water. After centrifugation (6000 rpm for 15 min at 4°C) to remove insoluble materials, protein concentrations are determined using Protein Assay Rapid Kit. The lysates are incubated at 37°C with the corresponding 4-methylumbelliferyl β-D-glycopyranoside solution in 0.1 M citrate buffer (pH 4). The liberated 4-methylumbelliferone is measured with a fluorescence plate reader (excitation 340 nm; emission 460 nm). For enzyme inhibition assay, cell lysates from normal skin fibroblasts are mixed with the 4-methylumbelliferyl β-D-glycopyranoside substrates in the absence or presence of increasing concentrations of Fagomine [1].
Cell Research Human skin fibroblasts from a healthy and three Gaucher disease patients (with N188S/G183W, V230G/R296X, and L444P/L444P mutations) are maintained in DMEM supplemented with 10% FBS as the culture medium. For enzyme activity enhancement assay, cells are cultured in the presence of different concentrations of Fagomine or DMSO alone (as a control) for 5 days and harvested by scraping. Cytotoxicity of Fagomine is monitored by measuring the lactate dehydrogenase activities in the cultured supernatants [1].
Animal Research Sprague-Dawley rats (male, 22 weeks old) are randomly assigned to one of the three dietary groups: the control group fed a standard diet (STD); a group fed HFHS (modified high-fat high-sucrose diet); a group fed HFHS supplemented with 0.065% Fagomine (HFHS+FG). The percentage of Fagomine is adjusted so that its ratio to sucrose is 2 mg/g, as defined before from the results of post-prandial tests. The modified diets are processed. Feed consumption is monitored every day throughout the experiment and body weight is measured before and at the end of the nutritional intervention. All animal manipulations are carried out in the morning to minimize the effects of circadian rhythms [3].
