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)

Synthesis, Characterisation and Luminescent Properties of Lanthanide-Organic Polymers with Picolinic and Glutaric Acids [PDF]

open access: yes, 2007
Three new lanthanide(III) complexes (Ln = Sm, Tb and Eu) of picolinic and glutaric acid were prepared and characterised. The crystal structure of the complex [Sm(glu)(pic)- (H2O)2] (where Hpic and H2glu stand for picolinic and glutaric acid ...

Transition-metal-free decarboxylative halogenation of 2-picolinic acids with dihalomethane under oxygen conditions

Green Chemistry, 2019
The reaction of 2-picolinic acids with dihalomethane proceeded smoothly via N-chlorocarbene intermediates to afford 2-halogen-substituted pyridines in satisfactory to excellent yields under oxygen conditions.
