β-Nicotinamide mononucleotide (β-NMN) is an intermediate in the biosynthesis of nicotinamide adenine dinucleotide (NAD+; Item No. 16077). Nicotinamide phosphoribosyltransferase (Nampt) catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to generate β-NMN, which is subsequently converted to NAD+ by β-NMN adenyltransferase.{19182} At 50-100 µM, β-NMN has been used to enhance NAD biosynthesis and glucose-stimulated insulin secretion in a Nampt+/- mouse model of metabolic disease, demonstrating a role for Nampt in β cell function.{19185} Furthermore, at 500 mg/kg/day, it has been shown to ameliorate glucose intolerance in high-fat diet-induced type 2 diabetes mice by restoring NAD+ levels.{20366}
