In situ identifying sennoside A-reducing bacteria guilds in human gut microbiota via enzymatic activity visualization

open access: yesGut Microbes
The intestinal environment determines the biochemical activity of individual microbial strains. The functions of microbial strains in their native environments often cannot be accurately predicted based solely on genomic information or the biochemical ...

Use of nfsB, encoding nitroreductase, as a reporter gene to determine the mutational spectrum of spontaneous mutations in Neisseria gonorrhoeae [PDF]

open access: yes, 2009
Background: Organisms that are sensitive to nitrofurantoin express a nitroreductase. Since bacterial resistance to this compound results primarily from mutations in the gene encoding nitroreductase, the resulting loss of function of nitroreductase ...

Nitroaryl Phosphoramides as Novel Prodrugs for E. coli Nitroreductase Activation in Enzyme Prodrug Therapy

open access: yes, 2016
Cyclic and acyclic nitroaryl phosphoramide mustard analogues were activated by E. coli nitroreductase, an enzyme explored in GDEPT. The more active acyclic 4-nitrobenzyl phosphoramide mustard (7) showed 167 500× selective cytotoxicity toward ...

Oncolytic adenovirus vectors for nitroreductase suicide gene therapy of prostate cancer [PDF]

open access: yes, 2010
Prostate cancer is the most common male cancer in the UK and USA, with a 1/13 chance of diagnosis and a 1/30 lifetime risk of death from the disease. Current treatment options include radiotherapy, surgery and hormone therapy, however 1/3 patients escape

Cell-Specific Chemical Delivery Using a Selective Nitroreductase–Nitroaryl Pair [PDF]

open access: yes, 2018
The utility of small molecules to probe or perturb biological systems is limited by the lack of cell-specificity. ‘Masking’ the activity of small molecules using a general chemical modification and ‘unmasking’ it only within target cells could overcome ...

Application of enzyme-responsive fluorescent probes in detecting drug-resistant bacteria

open access: yesNantong Daxue xuebao. Ziran kexue ban
With the overuse of clinical antibiotics, the types and varieties of drug-resistant bacteria are continually increasing. The timely and accurate identification of bacterial strains is crucial for the prevention and control of drug-resistant bacteria and ...

A mammalianized synthetic nitroreductase gene for high-level expression

open access: yesBMC Cancer, 2009
Background The nitroreductase/5-(azaridin-1-yl)-2,4-dinitrobenzamide (NTR/CB1954) enzyme/prodrug system is considered as a promising candidate for anti-cancer strategies by gene-directed enzyme prodrug therapy (GDEPT) and has recently entered clinical ...

Mutagenic activation of CL64,855, an anti-Trypanosoma cruzi nitroderivant, by bacterial nitroreductases

open access: yesGenetics and Molecular Biology, 1998
CL64,855 is a nitroimidazole-thiodiazole derivate with high anti-Trypanosoma cruzi activity. CL64,855-induced mutagenesis in the Salmonella/microsome test was detected by TA98 and TA98dnp6 strains, but not by the nitroreductase I-deficient TA98nr strain.
