IUPAC name: Pyridine-3-carboxamide[1]
Molecular Formula: C6H7N2O[1]
Molecular Weight: 122.12464 [g/mol] [1]
2D Structure: [2]
Functional Group: The structure consists of a pyridine ring with an amide group in position three.[1]
Chemical Nature: Freely soluble in water, in alcohol and soluble in Glycerene. Stable under normal temperatures and conditions. Niacinamide is incompatible with strong alkalis and strong acids and also with strong oxidizing agents. Burning may produce hazardous combustion gases like Nitrogen oxides, carbon monoxide, carbon dioxide[3]
Actions & Indications: Pharmcological Action-
Vitamin B complex - A group of water-soluble vitamins. [4]
Anxiolytic agent[5]
Antioxidant Action[6]
Reversal of HIV-induced metabolic abnormality by nicotinamide is reported[7]
Oral antimicrobial agent (In vivo anti-M. tuberculosis activity is reported)[8]
Therapeutic use -
Nicotinamide acts as a specific antidote for Vacor(PNU) rodenticide poisoning[9]
Niacinamide is used to prevent and treat niacin/Vitamin B3 deficiency states[10][11]and to treat pellagra.[6]
Niacinamide has been used successfully to prevent or delay the onset of type 1 diabetes among high-risk individuals.[4]
