Microbial oxidation of kynurenic, xanthurenic and picolinic acids

Biochimica et Biophysica Acta, 1963
Abstract 1. 1. Resulta of a study of the degradation of kynurenic acid by an Aerococcus are in agreement with a reaction sequence proposed for Pseudomonas by other workers. This sequence includes Compounds I and II below. 2. 2. Partial inhibition of oxidation of kynurenic acid by cell suspensions caused an accumulation of pyruvate with ...

6-Phosphoryl Picolinic Acids as Europium and Terbium Sensitizers

Inorganic Chemistry, 2011
Three 6-phosphoryl picolinic acid (6PPA) derivatives were synthesized and used as europium and terbium sensitizers. Two of the three ligands (6-diethoxyphosphoryl picolinic acid (Hdeppa) and 6-monoethoxyphosphoryl picolinic acid (H(2)meppa)) are water-soluble, once complexed to lanthanide ions, while the third (6-dihydroxyphosphoryl picolinic acid (H(3)

Picolinic acid as a matrix for laser mass spectrometry of nucleic acids and proteins

Rapid Communications in Mass Spectrometry, 1994
AbstractWe found that picolinic acid is a very good matrix for matrix‐assisted laser desorption/ionization (MALDI) time‐of‐flight mass spectrometry of oligonucleotides, proteins and tRNA. Among the oligonucleotides, picolinic acid was shown to be effective for homo‐oligonucleotides, d(G)40 and d(C)60, and for mixed‐base oligonucleotides up to 190 bases.
