Recently, new insecticides containing 3-chloropyridylmethyl group as a versatile building block have been developed, among which imidachloprid is a promising one. The synthesis of imidachloprid can use 6-Hydroxynicotinic acid, the first intermediate of the bacterial degradation of nicotinic acid, as

Journal of bacteriology, 165(1), 304-307 (1986-01-01)
Rhizobium sp. strain ORS571 conducts synergistic, free-living N2 fixation and nicotinate oxidation. Explicitly, ORS571 is able to fix N2 aerobically because 6-OH-nicotinate acts as an intracellular O2 sink. Because 6-OH-nicotinate oxidation is mandatory for aerobic, free-living N2 fixation and because

Journal of chromatography, 338(1), 51-59 (1985-02-27)
Gas chromatography--mass spectrometry has been used to identify specific metabolites produced by Gram-negative bacteria such as Pseudomonas aeruginosa, Serratia marcescens, Klebsiella pneumoniae and Escherichia coli in a defined medium. 6-Hydroxynicotinic acid was detected in spent culture media of Pseudomonas aeruginosa
C M Puah et al.
Urological research, 10(2), 81-84 (1982-01-01)
A sensitive and reliable radioimmunoassay (RIA) for urinary unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol is described. The mean overall recovery of unconjugated 5 alpha-androstane-3 alpha, 17 beta-diol was found to be 57.4%. The sensitivity of the assay was 79 fmol

Cancer detection and prevention, 28(1), 8-16 (2004-03-26)
Selenium (Se) and selenomethionine (Se-Met) have been identified as potential chemopreventive agents of prostate cancer. Using an assay for the speciation (separation and identification) and quantification of selenoamino acids, Se-Met was profiled in serum and prostate tissue from prostate cancer
Arun Sreekumar et al.
Nature, 457(7231), 910-914 (2009-02-13)
Multiple, complex molecular events characterize cancer development and progression. Deciphering the molecular networks that distinguish organ-confined disease from metastatic disease may lead to the identification of critical biomarkers for cancer invasion and disease aggressiveness. Although gene and protein expression have

The current technology for microbial hydroxylation of nicotinic acid is a procedure of resting cells transformation. Here it was reported that non-degradation of 6-hydroxynicotinic acid during hydroxylation of nicotinic acid by resting cells was due to existing of nicotinic acid
Ashish Gupta et al.
NMR in biomedicine, 18(5), 293-299 (2005-03-11)
The utility of (1)H NMR spectroscopy is suggested and demonstrated for the diagnosis of Pseudomonas aeruginosa in urinary tract infection (UTI). The specific property of P. aeruginosa of metabolizing nicotinic acid to 6-hydroxynicotinic acid (6-OHNA) is exploited. The quantity of

The American journal of clinical nutrition, 86(3), 672-681 (2007-09-08)
Previous studies suggest that high plasma concentrations of carotenoids, retinol, or tocopherols may reduce the risk of prostate cancer. We aimed to examine the associations between plasma concentrations of 7 carotenoids, retinol, alpha-tocopherol, and gamma-tocopherol and prostate cancer risk. A

6-Hydroxypyridine-3-carboxylic acid (6-HOPy-3-CO(2)H) reacts with Ln(2)O(3) (Ln = Nd, Sm, Eu, Gd) and oxalic acid (H(2)OX) under hydrothermal conditions to generate four novel lanthanide-organic coordination polymeric networks [Ln(2)(1H-6-Opy-3-CO(2))(2)(OX)(2)(H(2)O)(3)] x 2.5 H(2)O (Ln = Nd, 1; Sm, 2; 1H-6-Opy-3-CO(2)(-) = 1-hydro-6-oxopyridine-3-carboxylate)
Dayun Zhao et al.
Analytical and bioanalytical chemistry, 401(7), 2259-2273 (2011-08-27)
A new molecularly imprinted polymer (MIP) has been prepared on silica beads using the radical "grafting from" polymerization method for selective extraction of minor contaminant mycotoxin of patulin (PTL). After the introduction of amino groups onto the silica surface with

The relationship between energetics and structure in 2-, 4-, 5-, and 6-hydroxynicotinic and 5-chloro-6-hydroxynicotinic acids (2HNA, 4HNA, 5HNA, 6HNA, and 5Cl6HNA, respectively) was investigated in the solid and gaseous phases by means of a variety of experimental and computational chemistry
José Ignacio Jiménez et al.
Environmental microbiology, 13(7), 1718-1732 (2011-04-01)
The biochemistry of nicotinic acid (NA) degradation is known but the transcriptional control of the genes involved is still poorly studied. We report here the transcriptional regulatory circuit of the nic genes responsible for the aerobic degradation of NA in

Autosomal dominant polycystic kidney disease (ADPKD) is a frequent cause of kidney failure; however, urinary biomarkers for the disease are lacking. In a step towards identifying such markers, we used multidimensional-multinuclear nuclear magnetic resonance (NMR) spectroscopy with support vector machine-based

Journal of bacteriology, 174(23), 7791-7797 (1992-12-01)
A complete pathway for Azorhizobium caulinodans nicotinate catabolism has been determined from mutant phenotype analyses, isolation of metabolic intermediates, and structural studies. Nicotinate serves as a respiratory electron donor to O2 via a membrane-bound hydroxylase and a specific c-type cytochrome
