α-/β-Glucosidase and α-Amylase Inhibitory Activities of Roselle (Hibiscus sabdariffa L.) Ethanol Extract

open access: yesMCBS (Molecular and Cellular Biomedical Sciences), 2017
Background: Diabetes mellitus is a metabolic disease, characterized by hyperglycemia due to disturbance in both insulin secretion and function. One of theurapeutic approaches is to reduce blood glucose levels by inhbiting α-/β-glucosidase and α-amylase ...

Anti-α-Glucosidase, SAR Analysis, and Mechanism Investigation of Indolo[1,2-b]isoquinoline Derivatives

open access: yesMolecules, 2023
To find potential α-glucosidase inhibitors, indolo[1,2-b]isoquinoline derivatives (1–20) were screened for their α-glucosidase inhibitory effects. All derivatives presented potential α-glucosidase inhibitory effects with IC50 values of 3.44 ± 0.36~41.24 ±

Purification and characterization of two extracellular β-glucosidases fromAspergillus nidulans [PDF]

open access: yesFEMS Microbiology Letters, 1992
Two β-glucosidases, P-I and P-II, were purified from the culture filtrate of Aspergillus nidulans. The Mr values of P-I and P-II were about 125 000 and 50 000, respectively. The isoelectric point, optimal pH and temperature, Michaelis constants for several substrates and inhibition constants for glucose and glucono-δ-lactone of each enzyme were ...

Inhibitory Mechanism of Engeletin Against α-Glucosidase

open access: yesNatural Product Communications, 2021
The inhibitory mechanism of engeletin against α-glucosidase was investigated for the first time by fluorescence spectroscopy and molecular docking. The results showed that engeletin could inhibit α-glucosidase in a noncompetitive inhibition mode with a ...

In vitro α-glucosidase inhibitory activity of Tamarix nilotica shoot extracts and fractions.

open access: yesPLoS ONE, 2022
α-glucosidase inhibitors represent an important class of type 2 antidiabetic drugs and they act by lowering postprandial hyperglycemia. Today, only three synthetic inhibitors exist on the market, and there is a need for novel, natural and more efficient ...

Extracellular α-glucosidase of an alkalophilic microorganism,Bacillussp. ATCC 21591 [PDF]

open access: yesFEMS Microbiology Letters, 1983
Bacillus sp. ATCC 21591, an alkalophilic bacterium, produces 3 enzymes associated with degradation of starch-α-amylase, pullulanase and α-glucosidase. The latter reached a maximum after 24 h growth. Highest activities of α-glucosidase and pullulanase were obtained when the initial pH of the medium was 9.7 and although at pH 10.4 highest biomass was ...

Synthesis and bioactivities evaluation of oleanolic acid oxime ester derivatives as α-glucosidase and α-amylase inhibitors

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2022
Different oleanolic acid (OA) oxime ester derivatives (3a-3t) were designed and synthesised to develop inhibitors against α-glucosidase and α-amylase. All the synthesised OA derivatives were evaluated against α-glucosidase and α-amylase in vitro.
