FLAVONOIDS FROM RHYNCHOSIA PSEUDO-CAJAN AS SUITABLE α-GLUCOSIDASE INHIBITORS AND FREE RADICAL SCAVENGERS

International Research Journal of Pharmacy, 2014
A series of nine flavonoids , 1 - 9, isolated from Rhynchosia pseudo - cajan Cambe ss., ha s been investigated in present work for their biological potential against α - glucosidase, lipoxygenase (LOX), acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) enzymes ; and antioxidant activity against diphenylpicrylhydrazyl (DPPH) radica l ...

Chemoenzymatic Radiosynthesis of a Gluconate Transporter‐Targeted In Vivo Bacterial Sensor From Clinical [18F]FDG

Angewandte Chemie, EarlyView.
An efficient radiosynthesis of fluorine‐18 labeled gluconic acid ([18F]FGA) was developed using two readily available materials, 2‐deoxy‐2‐[18F]fluoro‐D‐glucose ([18F]FDG) and glucose oxidase. [18F]FGA is highly specific for bacterial gluconate metabolism mediated by gluconate permease (GntP) and gluconate kinase (GntK), with rapid clearance, low off ...

Evaluation of cannabidiol’s inhibitory effect on alpha-glucosidase and its stability in simulated gastric and intestinal fluids

Journal of Cannabis Research, 2021
Objective Cannabidiol (CBD) has been reported to have anti-diabetic effects in pre-clinical and clinical studies but its inhibitory effects on α-glucosidase, a carbohydrate hydrolyzing enzyme, remain unknown. Herein, we evaluated CBD’s inhibitory effects

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Unraveling A4GALT Mechanism and Its Modulation With Adamantyl‐Galactosylceramide Analogues: Advancing Fabry Disease Therapeutic Strategies

Angewandte Chemie, EarlyView.
A 310‐helix‐mediated conformational switch promotes a front‐face SNi‐like catalysis by human A4GALT. Mechanism‐guided design identifies AdaGalCer as a selective modulator of globotriaosylceramide (Gb3) biosynthesis, opening a clear route toward new Fabry disease therapeutics.

Glucosidase-Catalyzed Hydrolysis of α-d-Glucopyranosyl Pyridinium Salts:  Kinetic Evidence for Nucleophilic Involvement at the Glucosidation Transition State

, 2016
Kinetic isotope effects (KIEs) on the yeast α-glucosidase-catalyzed hydrolysis of two α-d-glucopyranosyl pyridinium salts were measured at 25 °C and pH = 6.8. The measured KIEs on kcat for the 2H-2, 13C-1, and 15N-1‘ labeled substrates α-d-glucopyranosyl

Partial purification and biochemical characterization of a soluble α-glucosidase II-like activity fromCandida albicans [PDF]

FEMS Microbiology Letters, 2004
A soluble α-glucosidase was partially purified from Candida albicans cells by a three-step procedure consisting of size-exclusion, ion-exchange and adsorption chromatographies. After the last step, enzyme was enriched about 8.7-fold with a yield of 13% over the starting material and analysis of the purified preparation revealed two major polypeptides ...

and α-Glucosidase Inhibitory Activity of Perfoliatin a from

Natural Product Communications, 2019
As part of our effort to discover new α-glucosidase inhibitors from natural sources, it was found that an aqueous extract from Melampodium perfoliatum (Cavanilles) Kunth (Asteraceae) inhibited the activity of rat-intestinal α-glucosidases in a ...

Selection and study of mutants ofDekkera intermediaandCandida wickerhamiiderepressed for β-glucosidase production [PDF]

FEMS Microbiology Letters, 1985
Mutants of Candida wickerhamii and Dekkera intermedia, derepressed for β-glucosidase biosynthesis, were isolated. These mutants were also shown to hyperproduce this enzyme. In anaerobic culture, the C. wickerhamii mutant still hyperproduced β-glucosidase and was derepressed. Glucose-cellobiose anaerobic fermentation by this strain was thus improved. On
