Preparation of 2- and 6-pyridones of N1-methylnicotinamide.
In the course of experiments designed to elucidate the structure of reduced diphosphopyridine nucleotide (DPNH) (12), it became necessary to prepare the 2and 6-pyridones of iV-methylnicotinamidel by oxidation of the latter. Huff (5) has described the preparation of N’-methyl-6-pyridone-3-carboxylic acid by alkaline ferricyanide oxidation of either trigonelline or N’-methylnicotinamide. The acid...

متن کاملexploring motivation and english test preparation strategies of iranian pre-university candidates during and at the end of test preparation period for konkur examination
the current study aimed at investigating the relationship between motivation and test preparation strategies (tpss) used by iranian pre-university students in their preparation period for the university entrance exam (uee). due to the importance of uee in iran, this study also attempted to show its impact on these two important variables. to this end, 100 pre-university students in an iranian p...
A fluorometric method for the determination of the 6-pyridone of N1-methylnicotinamide in urine.
Since Knox and Grossman demonstrated the excretion by man of the 6-pyridone of N’-methylnicotinamide (hereafter referred to as the pyridone) in appreciable amounts after the ingestion of nicotinamide (2), it became necessary to devise a method for its quantitative estimation in urine. Knox and Grossman isolated the compound from human urine and described its properties, including its ultraviole...
متن کاملEstimation of aldehyde oxidase activity in vivo from conversion ratio of N1-methylnicotinamide to pyridones, and intraspecies variation of the enzyme activity in rats.
The in vivo conversion ratio of N1-methylnicotinamide (NMN) to N1-methyl-2-pyridone-5-carboxamide (2-PY) and N1-methyl-4-pyridone-3-carboxamide (4-PY) as a parameter for the estimation of aldehyde oxidase level in rats was examined. NMN and its pyridones (2-PY and 4-PY) are usually detected in the urine of rats. When we measured the ratio of the amount of pyridones to the total amount of NMN an...
