The pathway for the biosynthesis of N1-Methyl-4-pyridone-3-carboxamide

Archives of Biochemistry and Biophysics, 1966
N 1 -Methyl-4-pyridone-3-carboxamide, a major metabolite of nicotinic acid and nicotinamide, has been found to be synthesized from N 1 -methylnicotinamide, the biosynthesis being catalyzed by a soluble enzyme system present in liver. In the presence of potassium ferricyanide, the oxidation of N 1 -methylnicotinamide occurred in the absence of ...

Synthesis and physical properties of new 4-pyridone extractants

Journal of Inorganic and Nuclear Chemistry, 1974
Abstract The synthesis and physical properties of 3-hydroxy-2-methyl-1-phenyl-4-pyridone (HX) and 3-hdroxy-2-methyl-1-(4-tolyl)-4-pyridone (HY) are described and discussed. The ionization constants of HX and HY were determined spectrophotometrically and by potentiometric titration.
