Tripodal trisamides based on nicotinic and picolinic acid derivatives

Canadian Journal of Chemistry, 1998
A number of polydentate arylamide ligands have been prepared by coupling various acyclic tripodal or linear polyamines with derivatives of nicotinic and picolinic acids. Two synthetic procedures were utilized; tris{[(2-hydroxynicotinyl)carbonyl]-2-aminoethyl}amine (H3NICTREN) was prepared by Method A, the HOSu/DCC method, and the other arylamides in ...

Influence of Dietary Picolinic Acid on Mineral Metabolism in the Rat

Annals of Nutrition and Metabolism, 1988
Male rats were fed isonitrogenous, isocaloric diets containing different amounts of dietary zinc and picolinic acid (PA) (25, 60, 120 ppm Zn, 0, 20, 40, 60 mmol PA/kg diet) and balance collections of urine and faeces made over a 4-day period. Rats fed 25 ppm Zn were in negative Zn and Cu balance during the experiment.

Application of Organolithium and Related Reagents in Synthesis. XV. A Concise Regiospecific Conversion of Picolinic- and Isonicotinic Acids into 2-Benzoyl- and 4-Benzoylnicotinic Acids

, 1994
The synthesis of the azaphthalides (7) and (8) and their conversion into the corresponding 2- and 4-benzoyl-3-hydroxymethylpyridines (9) and (10), very useful precursors of the 2- and 4-benzoylated nicotinic acids (11) and (12), as a way of regiospecific

Zinc Absorption in Cattle with a Dietary Picolinic Acid Supplement

The Journal of Nutrition, 1981
The effect of picolinic acid and hydroxyquinolines in intestinal zinc absorption of cattle was studied. In contrast to reports of the absorption in rat and in man, picolinic acid did not enhance zinc absorption in cattle. In two calves suffering from Adema disease, the bovine parallel to Acrodermatitis enteropathica, hydroxyquinoline supplementation ...
