NCIt definition : The active form of vitamin B3 and a component of the coenzyme nicotinamide adenine
dinucleotide (NAD). Niacinamide acts as a chemo- and radio-sensitizing agent by enhancing
tumor blood flow, thereby reducing tumor hypoxia. This agent also inhibits poly(ADP-ribose)
polymerases, enzymes involved in the rejoining of DNA strand breaks induced by radiation
or chemotherapy.;
Alternative definition : NCI-GLOSS: A nutrient in the vitamin B complex that the body needs in small amounts
to function and stay healthy. Niacinamide helps some enzymes make energy in the cell.
It is found in many plant and animal products. It is water-soluble (can dissolve in
water) and must be taken in daily. It is being studied to increase the effect of radiation
therapy on tumor cells.;
