β-nicotinamide mononucleotide is a product of the nicotinamide phosphoribosyltransferase (NAMPT) reaction and a key NAD+ intermediate. The pharmacological activities of β-nicotinamide mononucleotide include its role in cellular biochemical functions, cardioprotection, diabetes, Alzheimer's disease, and complications associated with obesity[1].
Intracellular NAD + levels were significantly reduced by knocking down or knocking down Nampt or treated with the Nampt inhibitor FK866, whereas NAD + levels were significantly increased by supplementation with NAD + precursors NAM or β-Nicotinamide mononucleotide [3].Treatment of β-nicotinamide mononucleotide, a precursor of NAD+, to HEK293 cells activated and improved the rate of mtDNA replication by increasing nucleotides in mitochondria and decreasing their degradation products: nucleosides. β-Nicotinamide mononucleotide metabolism plays a role in supporting mtDNA replication by maintaining the nucleotide pool balance in the mitochondria[7].
After β-Nicotinamide mononucleotide administration, there was no difference in blood glucose levels in GTTs between Nampt+/- and control female mice. In addition, β-Nicotinamide mononucleotide-treated Nampt+/- and control mice also had similar plasma insulin levels at each time point. β-Nicotinamide mononucleotide administration corrects the defect in GSIS observed in Nampt+/- mice[2]. β-nicotinamide mononucleotide ameliorates glucose intolerance by restoring NAD+ levels in HFD-induced T2D mice. β-nicotinamide mononucleotide also enhances hepatic insulin sensitivity and restores gene expression related to oxidative stress, inflammatory response, and circadian rhythm, partly through SIRT1 activation[4].In a mouse model induced by doxorubicin administered in divided low doses as in the clinics, supplementing mice with a precursor of NAD+ prevented the mtDNA depletion and cardiac dysfunction[5].When investigated whether β-Nicotinamide mononucleotide is superior to nicotinamide (Nam) as a precursor of NAD+ in whole animal experiments. β-Nicotinamide mononucleotide is retained in the body for longer than Nam[6].

β-烟酰胺单核苷酸是烟酰胺磷酸核糖转移酶（NAMPT）反应的产物,也是关键的NAD+中间体。β-烟酰胺单核苷酸的药理活性包括其在细胞生化功能、心脏保护、糖尿病、阿尔茨海默氏症以及与肥胖相关并发症方面的作用[1]。
通过敲除或抑制Nampt,或使用Nampt抑制剂FK866处理,细胞内NAD+水平显著降低；而通过补充NAD+前体物质NAM或β-烟酰胺单核苷酸,则可以显著增加NAD+水平。将β-烟酰胺单核苷酸作为NAD+的前体物质添加到HEK293细胞中,可以通过增加线粒体中的核苷酸并减少其降解产物（即核苷）来激活和改善mtDNA复制速率。 β-烟酰胺单核苷酸代谢在支持mtDNA复制方面发挥作用,通过保持线粒体中的核苷酸池平衡来实现这一点。
在给β-烟酰胺单核苷酸注射后,Nampt+/-和对照组雌性小鼠的葡萄糖耐量试验中血糖水平没有差异。此外,接受β-烟酰胺单核苷酸治疗的Nampt+/-和对照组小鼠在每个时间点上也具有相似的血浆胰岛素水平。 β- 烟酰胺单核苷酸治疗纠正了观察到的Nampt+/-小 鼠中GSIS缺陷[2]。 β- 烟 酰 胺 单 核 苷 酸 通过恢复HFD诱导T2D小 鼠中NAD + 水平来改善葡萄 糖不耐受性。 β - 烟 酰 胺 单 核 苷 酸 还通过SIRT1激活部分增强肝脏胰岛素敏感性并恢复与氧化应激、炎性反应和昼夜节律相关基因表达[4]。 在以分割低剂量多柔比星诱导的小鼠模型中,用NAD + 前体物质补充可以防止mtDNA消耗和心脏功能障碍[5]。当研究β- 烟 酰 胺 单 核 苷 酸 是否优于烟酰胺（Nam）作为NAD + 前体物质的整体动物实验时,发现β- 烟 酰 胺 单 核 苷 酸在体内的保留时间比Nam长[6]。
