Inhibitory Effect of Coumarins and Isocoumarins Isolated from the Stems and Branches of Acer mono Maxim. against Escherichia coli β-Glucuronidase

Applied Sciences, 2022
We isolated eight known secondary metabolites, including two isocoumarins and six coumarins, from the stems and branches of Acer mono Maxim. Their structures were confirmed using nuclear magnetic resonance spectroscopy and by comparing the data to ...

Characterization of regions of the cyanobacterial tRNA^progene that affect the expression of a β-glucuronidase reporter gene [PDF]

FEMS Microbiology Letters, 2002
The E3 strong promoter-active fragment harbors the tRNA(pro) (GGG) gene upstream of the promoterless beta-glucuronidase (GUS) reporter gene in plasmid pKG-E3. The 74-bp tRNA(pro) coding sequence contains two regions exhibiting strong homology to blocks A and B which are the split promoter elements of eukaryotic tRNA genes.

Exploring Enzymatic Hydrolysis of Urine Samples for Investigation of Drugs Associated with Drug-Facilitated Sexual Assault

Pharmaceuticals, 2023
Analyzing urine is common in drug-facilitated sexual assault cases if the analysis of blood is not optimal. The efficient enzymatic pretreatment of urine is important for cleaving glucuronides and improving the detection of the parent drug.

Targeted inhibition of gut bacterial β-glucuronidase activity enhances anticancer drug efficacy

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Cancer chemotherapy often causes side effects that require modulations in dosing, which then reduce anticancer efficacy. Here, we show that targeted inhibition of gut bacterial enzymes alleviates key stages of gut epithelial damage caused by

Serum beta-glucuronidase determination in normal subjects and in neurological and mental patients, a provisional report [PDF]

, 1963
Using the method given by GOLDSTEIN (1961)9 for the determination of serum beta-glucuronidase activity, this value was determined in both normal and patients with epilepsy, neuroses, psychoses and multiple sclerosis.

Deconjugation Kinetics of Glucuronidated Phase II Flavonoid Metabolites by B-glucuronidase from Neutrophils [PDF]

, 2010
Flavonoids are inactivated by phase II metabolism and occur in the body as glucuronides. Mammalian ß-glucuronidase released from neutrophils at inflammatory sites may be able to deconjugate and thus activate flavonoid glucuronides.

Flavonoid glucuronides are substrates for human liver β-glucuronidase [PDF]

, 2001
Quercetin glucuronides are the main circulating metabolites of quercetin in humans. We hypothesise that the potential availability of the aglycone within tissues depends on the substrate specificity of the deconjugating enzyme β-glucuronidase towards ...

Effect of Lactobacillus plantarum LS/07 on Intestinal Bacterial Enzyme Activities in the Prevention of Cancer, Atherosclerosis and Dysbiosis

Acta Veterinaria, 2016
The effect of the probiotic strain Lactobacillus plantarum LS/07 on intestinal bacterial enzyme activities – β-glucuronidase (β-GLUCUR), β-galactosidase (β-GAL), and β-glucosidase (β-GLU) in the prevention of cancer, atherosclerosis and dysbiosis was ...
