Radioactively labelled octyl-[beta]-D- glucopyranoside was used as a model compound to analyze the stability and enzymatic activity of the in vitro system.
Flavonoids with unsubstituted hydroxyl groups in [C.sub.3], and [C.sub.4], position (5 and 6) showed potent activity; however, a compound with C-4' methoxy substitution, 4'-0-methylquercetin 3-O-[beta]-D glucopyranoside (7), did not show any activity in the free radical-scavenging assay.
[53], the anti-inflammatory activities of amentoflavone, apigenin-7-O-[beta]-D-glucopyranoside, acacetin-7-O-[beta]-D-[[alpha]-L-rhamnosyl (1 [right arrow] 6)]3"-E-p-coumaroyl glucopyranoside and rutin were assessed by measuring the levels of IL-1[beta], IL-6, and TNF-[alpha] in the supernatant media of human peripheral blood mononuclear cells (PBMCs) stimulated by phytohemagglutinin.
capillaris, we purified a novel enhancer of pigmentation: isofraxidin 7-O-(6'-O-p-coumaroyl)-[beta]- glucopyranoside (compound 1; Figure 1(a)).
Pinoresinol-4-0-[6"-0-(E)-feruloyl]-[beta]-D- glucopyranoside was the strongest inhibitor of TNF-[alpha] as evidenced from its higher fitting scores comparable to lead compound.
For pyranose sugar benzoates, our first effort was to prepare methyl tetra-O-benzoyl-D glucopyranoside. Thus, benzoylation of methyl [alpha]-D-glucopyranoside (6) afforded a white solid, mp 90-92 [degrees]C in 85% yield.
Starch is a semicrystalline polysaccharide composed of linear amylase (poly-[alpha]-1,4-D- glucopyranoside) and branched amylopectin (poly-[alpha]-1,4-D-glucopyranoside and [alpha]-1,6-D-glucopyranoside).
(2004) employed 4 - methylumbelliferyl - phosphor - b - d- glucopyranoside for the screening of glucosidase gene of Bacillus subtilis.
However it was unable to utilize sucrose, raffinose, adonitol, methyl A-D mannoside, inositol, xylitol, isobutyrate, methyl A-D glucopyranoside, salicin, D-melizitose and hippurate.
P-Nitrophenyl-[beta]-D- glucopyranoside (p-NPG) was used in assays for [beta]-glucosidase activity (Ferraz et al.
