Aplicação

Nicotinamide has been used:
  • to study its effect on the expression of sirtuin 1
  • in nicotinamide adenine dinucleotide/nicotinamide adenine dinucleotide phopshate (NAD+/NADH) cycling assay
  • in cell lysis buffer, to serve as a sirtuin 1 inhibitor in order to study its role in resveratrol (RSV)-stimulated hepatitis B virus replication

Ações bioquímicas/fisiológicas

Nicotinamide is an amide derivative of vitamin B3 and a PARP inhibitor
The coenzymes NAD and NADP take part in energy yielding metabolism and mediate several oxidation-reduction reactions. NAD hydrolyses to form nicotinamide, which is then transported to other tissues. Hydrolysis of nicotinamide yields nicotinic acid through salvage pathway.
Nicotinamide (Niacinamide) (Nam) is a building block (active component) of coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phopshate (NADP). Nicotinamide may be used as a substrate of nicotinamide phosphoribosyltransferase (NAMPT, EC 2.4.2.12), the rate-limiting enzyme for NAD(+) biosynthesis and an important signaling molecule.
