Nicotinamide is a form of vitamin B3 and is employed in various research studies for its role in biochemistry and cellular metabolism. It is a precursor of nicotinamide adenine dinucleotide (NAD+), a coenzyme involved in redox reactions and essential for ATP production. Researchers use Nicotinamide to study the NAD+ biosynthesis pathway and its impact on metabolic processes, as well as its role in the regulation of sirtuins, a class of proteins that depend on NAD+ and are implicated in gene silencing and longevity. In addition, Nicotinamide is used in enzymology to investigate the inhibition of poly(ADP-ribose) polymerases (PARPs), enzymes that utilize NAD+ in the repair of DNA damage. The compound has also been used in studies focused on circadian rhythms and the cellular aging process, given its influence on NAD+ levels and sirtuin activity.
