Three new depsidones, botryorhodines E-G (1-3), and two new isoindolinones, meyeroguillines A and B (7 and 9), along with five known compounds were isolated from an endophytic fungus Meyerozyma guilliermondii, derived from the mangrove plant Kandelia obovata. Their structures were elucidated by 1D and 2D NMR spectroscopy and high resolution mass spectrometry (HREIMS). Compounds 1-6 exhibited st...
The effect of feruloylated arabinoxylan mono- and oligosaccharides (FAXmo) on mammalian α-glucosidase and glucose transporters was investigated using human Caco-2 cells, rat intestinal acetone powder, and Xenopus laevis oocytes. The isolated FAXmo from wheat aleurone and corn bran were identified to have degree of polymerization (DP) of 4 and 1, respectively, by HPLC-MS. Both FAXmo extracts wer...
Diabetes mellitus is a chronic disease that is becoming a serious global health problem. Diabetes has been considered to be one of the major risks of cataract and retinopathy. Synthetic and natural product inhibitors of carbohydrate degrading enzymes are able to reduce type 2 diabetes and its complications. For a long time, potatoes have been portrayed as unhealthy for diabetic patients by some...
We have isolated two novel a-glucosidase inhibitors, O-[4-deoxy-4-(2,3-epoxy-3-hydroxymethyl-4,5,6-trihydroxycyclohexane-1-yl-amino)-alpha-D-glucopyranosyl]-(1-->4)-O-alpha-D-glucopyranosyl-(1-->4)-alpha-D-glucopyranose (named CKD-711) and its hexameric analog CKD-711a, from the fermentation broth of Streptomyces sp. CK-4416. HRFAB-MS and NMR analyses reveal that molecular formulae of CKD-711 a...
BACKGROUND A carbose is the first of a new class of antidiabetic agents, the alpha-glucosidase inhibitors. This study characterizes and identifies predictors of persistence of use of acarbose. METHODS Medical, pharmaceutical, and demographic records were extracted for 2 cohorts of patients (social assistance recipients and seniors) from the databases of Quebec's provincial health plan. Patien...
Hyperglycemia and hyperlipidemia have been symptoms of many serious diseases such as diabetes and atherosclerosis overall the world. Thus, drug researchers have focused on new, natural and healthy drug alternatives. Marine macroalgae is a great source of hypoglycemic, hypolipidemic or hypocholesterolemic agents. In this study, we investigated that hypoglycemic, hypolipidemic a...
the imported willow leaf beetle, plagiodera versicolora is one of the main pests of forest trees worldwide including iran. activities of α- and β-glucosidases in the midgut of p. versicolora adults were studied in this research. the results showed a higher α- glucosidase activity of adultsthan β-glucosidase. the optimal phs for α- and β-glucosidases activities were found to be 6 and 9, respecti...
The design of covalent inhibitors in glycoscience research is important for the development of chemical biology probes. Here we report the synthesis of a new carbocyclic mechanism-based covalent inhibitor of an α-glucosidase. The enzyme efficiently catalyzes its alkylation via either an allylic cation or a cationic transition state. We show this allylic covalent inhibitor has different catalyti...
