The biosynthetic pathway of nicotine involves a coupling reaction between the two cyclic structures that comprise nicotine. Metabolic studies show that the pyridine ring of nicotine is derived from niacin (nicotinic acid) while the pyrrolidine is derived from N-methyl-Δ 1-pyrrollidium cation.
Nicotinic acid was first synthesized in 1867 by oxidative degradation of nicotine with potassium chromate and sulfuric acid [82] — this is the origin of the name. [83] Niacin is prepared by hydrolysis of nicotinonitrile , which, as described above, is generated by oxidation of 3-picoline.
Nicotinamide riboside (NR) is now known to be an NAD+ precursor, involved in the biosynthetic pathways that convert B3 vitamins into NAD+. NAD+ is primarily synthesized in mammals de novo from tryptophan, through the Priess-Handler pathway from nicotinic acid (NA) or via a salvage pathway from nicotinamide (NAM).
The pyridine ring is part of two B vitamins: niacin and pyridoxine. Niacin, also called nicotinic acid, is found in most organisms. Niacin, also called nicotinic acid, is found in most organisms. Via metabolism, it becomes nicotinamide adenine dinucleotide NAD, a coenzyme which is involved in oxidation and reduction in metabolic cells.
[10] [11] It is an amide of nicotinic acid. [7] Foods that contain nicotinamide include yeast, meat, milk, and green vegetables. [12] Nicotinamide was discovered between 1935 and 1937. [13] [14] It is on the World Health Organization's List of Essential Medicines. [15] [16] Nicotinamide is available as a generic medication and over the counter ...
A pyridinecarboxylic acid is any member of a group of organic compounds which are monocarboxylic derivatives of pyridine. Pyridinecarboxylic acid comes in three isomers: Picolinic acid (2-pyridinecarboxylic acid) Nicotinic acid (3-pyridinecarboxylic acid), also known as Niacin; Isonicotinic acid (4-pyridinecarboxylic acid)
Since then it has been shown that a cationic center, atoms that are electronegative and able to form hydrogen bonds along with the center of the pyridine ring in (S)-nicotine are favorable. Stereochemistry is a part of the pharmacophore as is clearly seen with (S)- and (R)- nicotine where the (S)- enantiomer is 10-100 times more potent.
Dinicotinic acid can be formed by heating pyridine-2,3,5,6-tetracarboxylic acid or carbodinicotinic acid (pyridine-2,3,5-tricarboxylic acid). [2] [3] The acid is sparingly soluble in water and ether. Its melting point of 323 °C is the highest among pyridinedicarboxylic acids. Upon heating, it decarboxylates and decomposes to nicotinic acid: [4]
