The gastrointestinal effects of α-glucosidase inhibitors have not been sufficiently investigated. The aim of this study was to determine whether a single dose of pre-prandial voglibose might affect the rate of gastric emptying, determined using the (13)C breath test. Ten healthy male volunteers participated in this randomized, two-way crossover study. The subjects fasted overnight and received 0.2 mg voglibose or a placebo 2 h before a test meal. They were then served a liquid test meal consisting of 200 kcal per 200 ml that contained 100 mg (13)C-acetate...

A new series of Deacetylsarmentamide A and B derivatives, amides and sulfonamides of 3,4-dihydroxypyrrolidines as α-glucosidase inhibitors were designed and synthesized. The biological screening test against α-glucosidase showed that some of these compounds have the positive inhibitory activity against α-glucosidase. Saturated aliphatic amides were more potent than the olefinic amides. Among all the compounds, 5o/6o having polar -NH2 group, 10f/11f having polar -OH group on phenyl ring displayed 3-4-fold more potent than the standard drugs...

We analyzed the effects of 100 mg/day sitagliptin and a switch to mitiglinide calcium hydrate/voglibose compound tablets (MIT/VOG) in patients with type 2 diabetes mellitus (T2DM) treated with 50 mg/day sitagliptin. Five patients with T2DM treated with 50 mg/day sitagliptin and hemoglobin A1c (HbA1c) of ≥6.5% were switched to MIT/VOG, or the dose of sitagliptin was increased to 100 mg/day. The effects of the changes in therapy were compared in a crossover fashion by continuous glucose monitoring. The primary endpoint was mean amplitude of glycemic excursions (MAGE), and the secondary end points were 24-hour mean blood glucose level and mean blood glucose level from 0:00 a...

Melanocytes play an important role in maintaining epidermal homeostasis by producing melanin and protecting the skin from harmful environmental factors. However, excessive up- or down-regulation of melanin production often causes hyper- or hypo-pigmented disorders, respectively, which affect the patient's quality of life. Therefore, various strategies for modulating melanin levels have been developed by the pharmaceutical and cosmetic industries. We reported previously that voglibose, which is a well-known anti-hyperglycemic agent, could be used as an anti-melanogenic agent by inhibiting α-glucosidase activity and reducing tyrosinase protein levels...

Sucrose is a major sweetener added to various foods and beverages. Excessive intake of sucrose leads to increases in blood glucose levels, which can result in the development and exacerbation of lifestyle-related diseases such as obesity and diabetes. In this study, we established an in vivo evaluation system using silkworms to explore substances that suppress the increase in blood glucose levels caused by dietary intake of sucrose. Silkworm hemolymph glucose levels rapidly increased after intake of a sucrose-containing diet...

Voglibose, an N-1,3-dihydroxypropylaminocyclitol, has widely been used as an effective α-glucosidase inhibitor for diabetes therapy. Several attempts have been made to synthesize closely related analogues through the coupling of various aminocyclitols and propane-1,3-diol; however, most of them showed weaker or no inhibition. In this communication, we synthesized a pair of new N-1,3-dihydroxypropylaminocyclitols (10 and 11) using (+)-proto-quercitol (1) as a cyclitol core structure. The newly synthesized compounds revealed potent rat intestinal α-glucosidases, particularly against maltase, with IC50 values at submicromolar...
