Tetrodotoxin (TTX) is an extremely potent paralytic toxin responsible for yearly illness and death around the world. A clinical measurement is necessary to confirm exposure because symptoms of TTX intoxication cannot be distinguished from other paralytic toxins. Our group has developed an online solid phase extraction hydrophilic interaction liquid chromatography (HILIC) method for the analysis of TTX in human urine with tandem mass spectrometry. The reportable range for the method was 2.80 - 249 ng/mL in urine with precision and accuracy within 15% as determined for all quality control samples...

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...

We encountered a 62-year-old woman who experienced frequent episodes of hypoglycemia. She was diagnosed with postprandial reactive hypoglycemia according to the results of oral glucose and sucrose tolerance tests, having undergone an endocrinological examination and image inspection. The administration of low-dose voglibose, an alpha-glucosidase inhibitor (α-GI), improved the glucose fluctuations and inhibited hypoglycemic symptoms. Voglibose is also known to diminish oxidative stress and maintain endothelial function after hyperglycemia...

α-Glucosidase inhibitors (AGIs) are a class of oral glucose-lowering drugs used exclusively for treatment or prevention of type 2 diabetes mellitus. AGIs act by altering the intestinal absorption of carbohydrates through inhibition of their conversion into simple sugars (monosaccharides) and thus decrease the bioavailability of carbohydrates in the body, significantly lowering blood glucose levels. The three AGIs used in clinical practice are acarbose, voglibose and miglitol. This review will focus on the cardiovascular properties of acarbose...

The sodium-glucose cotransporter 2 (SGLT2) is responsible for most glucose reabsorption in the kidney and has been proposed as a novel therapeutic target for the treatment of type 2 diabetes. In the present study, the combinatory effects of SGLT2 selective inhibitor ipragliflozin and various antidiabetic drugs in high-fat diet and streptozotocin-nicotinamide-induced type 2 diabetic mice were investigated. Ipragliflozin dose-dependently increased urinary glucose excretion and improved glucose tolerance. In addition, each antidiabetic drug (mitiglinide, glibenclamide, sitagliptin, insulin, metformin, voglibose, or rosiglitazone) also significantly improved glucose tolerance without affecting urinary glucose excretion...

Usman Ghani
Treatment of diabetes mellitus by oral α-glucosidase inhibitors is currently confined to acarbose, miglitol and voglibose marred by efficacy problems and unwanted side effects. Since the discovery of the drugs more than three decades ago, no significant progress has been made in the drug development area of anti-diabetic α-glucosidase inhibitors. Despite existence of a wide chemical diversity of α-glucosidase inhibitors identified to date, majority of them are simply piled up in publications and reports thus creating a haystack destined to be forgotten in the scientific literature without given consideration for further development into drugs...
