An efficient and convenient method for the synthesis of [1,2,4]triazolo[4,3-a]pyridines was exemplified by the synthesis of 20 analogues bearing a variety of substituents at the 3-position. The methodology involves a palladium-catalyzed addition of hydrazides to 2-chloropyridine, which occurs chemoselectively at

A sensitive method using ion-pair extraction was developed by liquid chromatography tandem mass spectrometry (LC-MS/MS) for measurement of 4-methylimidazole (4-MI) in NMRI mice plasma and cerebrospinal fluid (CSF). Detection was done by electrospray positive ionization mass spectrometry in the multiple-reaction
The photolytic destruction and mineralisation of 2-halogenated pyridines (2-HalPYs) was studied in a range of conditions by means of ultraviolet irradiation at 254 nm. In all cases pseudo-first order kinetics satisfactorily describe the degradation process. Key decomposition products were identified
Contribution of N-oxidation and .OH radicals to mutagenesis of 2-chloropyridine in Salmonella typhimurium.
Drug metabolism and disposition: the biological fate of chemicals, 37(9), 1797-1800 (2009-06-23)
We investigated the substitution reaction of a series of 2-chloropyridine derivatives catalyzed by rat liver microsomal glutathione S-transferase 1. Various 2-chloropyridine derivatives were metabolized to the corresponding substituted glutathione conjugates via displacement of chlorine atom with glutathione. The reaction was
