New Guanidinium and Aminoguanidinim Salts of 2-Hydroxypyridine-3-carboxylic acid: Preparation and spectral, structural, thermal, ADMET, biological, and molecular docking studies

A one-pot solid-state synthesis of MgO nanoparticles and their catalytic, biological, and electrochemical sensor activities: hexaaquamagnesium(ii) bis(6-oxo-1,6-dihydropyridine-3-carboxylate) as a tool

“…This suggests that the 6-hydroxypyridine-3carboxylate anion was present in its pyridone form (keto form), that is, as the isomer with a keto group and a protonated N atom. The presence of the Mg ion and the water molecule's hydroxyl group resulted in the formation of N-HÁ Á ÁO and O-HÁ Á ÁO hydrogen bonds [35][36][37][38][39] (Fig. 3).…”
