Hypoglycemia is the most important complication of antidiabetic medications. Most patients with diabetes mellitus take multiple medications. In this study, we explored clinical drug-drug interactions that result in hypoglycemia by analyzing the Japanese Adverse Drug Event Report (JADER) database. The primary outcome was the report of hypoglycemia. The Norén and Gosho methods, which quantitatively measure the discrepancy between the observed and expected number of adverse events under the combination of 2 drugs, were used as the criteria for detecting drug-drug interactions...

Carbohydrate hydrolyzing α-glucosidases are commonly found in microorganisms present in the human intestine microbiome. We have previously reported crystal structures of an α-glucosidase from the human gut bacterium Blaubia (Ruminococcus) obeum (Ro-αG1) and its substrate preference/specificity switch. This novel member of the GH31 family is a structural homolog of human intestinal maltase-glucoamylase (MGAM) and sucrase-isomaltase (SI) with a highly conserved active site that is predicted to be common in Ro-αG1 homologs among other species that colonize the human gut...

Treatment-related quality of life (QOL) is an important aspect of diabetes management. However, no studies have compared the influence of dipeptidyl peptidase-4 inhibitors versus alpha-glucosidase inhibitors on treatment-related QOL. This prespecified sub-analysis of the Linagliptin Study of Effects on Postprandial blood glucose (L-STEP) compared the effects of linagliptin (5 mg once daily) and voglibose (0.2 mg/meal thrice daily) on treatment-related QOL in Japanese patients with type 2 diabetes (T2DM) inadequately controlled with diet and exercise therapy...

Biological evaluation of 3,4-dihydroxy piperidines as α-glucosidase inhibitors is being reported for the first time. Forty-five derivatives (amides, di-amides and sulfonamides) were made using cis and trans 3,4-dihydroxy piperidines to evaluate their α-glucosidase inhibition activity. Polar groups (-OH, -NH2 ) on phenyl ring having derivatives 5i, 5l, 7g, 7i &12j showed excellent activity compared to standard references. Acarbose, Voglibose and Miglitol were used as standard references. Molecular docking simulations were done for compounds to identify important binding modes responsible for inhibition activity of α-glucosidase...

 For patients with dysphagia in medical facilities and nursing homes, food thickeners are routinely used to aid the ingestion of medicines such as tablets. However, some types of thickeners affect the disintegration and dissolution of tablets, such as rapidly-disintegrating magnesium oxide tablets and donepezil hydrochloride orally disintegrating tablets. Additionally, delayed disintegration and dissolution of tablets affect a drug's efficacy. As an example, with Voglibose orally disintegrating tablets, marked differences are observed in changes in glucose levels during glucose tolerance testing...

In this work, magnetic graphene/mesoporous silica composites with carbon-functionalized pore-walls (denoted as MG@mSiO2 -C composites) were synthesized and applied as restricted access matrix solid phase extraction (RAM-SPE) adsorbents for the determination of miglitol and voglibose in rat plasma by LC-MS/MS. The MG@mSiO2 -C composites were synthesized by using the template (Cetyltrimethyl Ammonium Bromide, CTAB) as carbon source with sulfuric acid pretreated. The obtained nano-composites were proven to have many unique properties such as large specific surface area of 277...

The alpha-glucosidase inhibitor voglibose (VO) was recently reported to have a protective effect against weight gain as well as affect various metabolic changes related to food intake and gut-brain signaling. We hypothesized that VO prevents weight gain by altering neurometabolome profiles in the hypothalamus to reduce food intake. To test this hypothesis, we assessed metabolite profiles in the hypothalamus of standard diet- or high-fat (HF) diet-fed mice in the absence or presence of VO. In total, 29 male C57BL/6 mice were divided into 3 groups: (1) lean control, (2) HF, and (3) HF + VO...

Endothelial dysfunction contributes to poor cardiovascular prognosis in patients with type 2 diabetes mellitus (T2DM) and coronary artery disease (CAD). The effect of dipeptidyl peptidase-4 inhibitors on endothelial function remains controversial. We sought to compare the effects of linagliptin and voglibose on endothelial function, as assessed by reactive hyperemia-peripheral arterial tonometry (RH-PAT). Sixteen patients with newly diagnosed T2DM and CAD were randomized 1:1 to linagliptin (5 mg, once-daily) or voglibose (0...

Recently, we reported that linagliptin had equivalent efficacy to voglibose in reducing postprandial blood glucose levels in drug-naïve patients with type 2 diabetes (L-STEP Study). As a sub-study of the L-STEP Study we examined the effect of linagliptin on postprandial lipids profile. Between October 2012 and April 2014, the study enrolled patients with type 2 diabetes mellitus who had inadequate glycemic control. Patients were randomly assigned to either the linagliptin group (5 mg once daily, n = 85) or the voglibose group (0...

A facile and highly diastereoselective approach toward the synthesis of potent salacinol-type α-glucosidase inhibitors, originally isolated from plants of the genus "Salacia", was developed using the S-alkylation of thiosugars with epoxides in HFIP (∼90%, dr, α/β = ∼ 26/1). The dr ratio of the product was significantly improved by the protocol as compared to that of the conventional S-alkylation of thiosugars (dr, α/β = ∼ 8/1). The protocol could be used for gram scale synthesis of the desired compounds...

The overlap of multiple liver diseases can cause the disease activity and severity to worsen rapidly in some cases. We rarely see patients with non-alcoholic steatohepatitis (NASH) with overlapping autoimmune hepatitis (AIH). A 64-year-old woman who had been prescribed oral drugs to treat diabetes and hypertension (metformin 500 mg/day and voglibose 0.9 mg/day, and termisartan 40 mg/day and amlodipine 5 mg/day, respectively) was diagnosed with NASH with histological confirmation. At 68 years of age, her liver injury worsened with an IgG of 2,871 mg/dL and a high serum anti-nuclear antibody (ANA) level of 2,560...

Case: A 64-year-old Japanese woman with diabetes mellitus was admitted for hypoglycemia. Her diabetes had been under good control with glimepiride, voglibose, exenatide, and metformin for a few years. Although overt proteinuria was observed, the serum creatinine values were within normal range during the routine outpatient follow-up. Hypoglycemic attack caused by glimepiride and loss of appetite by urinary tract infection were diagnosed. Then, metformin-associated lactic acidosis with acute renal failure caused by dehydration was detected...

Clinicians sometimes encounter difficulty in diagnosing hypoglycaemia. Here, we present a case report of a 53-year-old woman with recurrent nocturnal hypoglycaemia. A continuous glucose monitoring system (CGMS) revealed postprandial hyperglycaemia and subsequent hypoglycaemia, and an oral glucose tolerance test showed an impaired glycaemic and delayed hyperinsulinaemic pattern. On the basis of these clinical findings, we diagnosed her unexplained hypoglycaemia as reactive hypoglycaemia. CGMS showed a sharp contrast of diurnal variation in blood glucose levels including hypoglycaemia between before and after treatment with an alpha-glucosidase inhibitor, voglibose...

Diabetic gastroparesis is a common complication of diabetes mellitus (DM) that is characterized by decreased serum insulin and insulin-like growth factor-1 (IGF-1). Despite the fact that insulin treatment not glycemic control potently accelerated gastric emptying in type 1 DM patients, the role of insulin/InsR and IGF-1/IGF-1R signaling in diabetic gastroparesis remains incompletely elucidated. In the present study, type 1 DM mice were established and treated with insulin or Voglibose for 8 weeks. The gastric emptying was delayed from DM week 4 when the gastric InsR and IGF-1R were declined...

BACKGROUND: Pneumatosis intestinalis (PI) is a rare condition characterized by the presence of gas within the gastrointestinal tract wall. Most cases of PI have a benign clinical course, although some have serious outcomes. Mechanical stress on or bacterial infection of the gastrointestinal tract wall may be responsible for the onset of PI, but the detailed mechanism of PI pathogenesis is still unclear. Here, we describe two Japanese patients presenting with benign PI. CASE PRESENTATION: Case 1, a 37-year-old previously healthy male patient, had a 1-week history of abdominal pain, and case 2, a 78-year-old female diabetic patient, had a 2-week history of voglibose treatment and abdominal pain...
