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-NPG) was used in assays for [beta]-glucosidase activity (Ferraz et al.
c) An Invertase Unit (IU) indicatess pmoles p-nitrophenyl glucopyranoside

005 * Spectrophotometric assay, [alpha]-para-nitrophenol glucopyranoside
After baseline blanking, activity against pNP [beta]-N acetylglucosamine and pNP a mannopyranoside were the highest although the activity against a glucopyranoside
and [beta] galactopyranoside were also high.
Approximately 1 mg of screened sample was weighed and placed into a test tube containing 50 [micro]L of methyl glucopyranoside
at 1 mg [mL.
was the strongest inhibitor of TNF-[alpha] as evidenced from its higher fitting scores comparable to lead compound.
ferruginea, but a bioassay guided fractionation of an extract showed that the compounds 5'demethoxy-[beta]-peltatin-5-O-[beta]-D- glucopyranoside
have cytotoxic and cytostatic activity in the NCI's 60 cell antitumour screen (Rashid 2000).
is a flavonoid isolated from the plant Dracocephalum tanguticum that is widely used in Chinese and Tibetan traditional medicine .
From roots, a naphthoquinone-anthraquinone coupled pigment--newbouldiaquinone A has been isolated with anti-malarial activity against Plasmodium falciparum and strong anti-microbial activities against Candida gabrata and Enterobacter aerogens; other components isolated from roots included apigenin, chrysoeriol, newbouldiaquinone, lapachol, 2-methylanthraquinone, 2-acetylfuro-1,4- naphthoquinone, 2,3-dimethoxy-1,4-benzoquinone, oleanolic acid, canthic acid, 2-(4- hydroxyphenyl)ethyl triacontanoate, newbouldiamide, 5,7-dihydroxydehydroiso-a- lapachone, b-sitosterol, and b-sitosterol glucopyranoside
