烟酰胺单核苷酸(英语:Nicotinamide Mononucleotide,缩写“NMN”或“β-NMN”)是一种由核糖和烟酰胺衍生的核苷酸。[1]与烟酰胺核糖苷一样,NMN是烟酸的衍生物,人类也有利用NMN生成烟酰胺腺嘌呤二核苷酸(NADH)的酶[1]。在小鼠中,NMN在10分钟内通过小肠进入细胞,通过Slc12a8 NMN转运体转化为NAD+。[2]
因为NADH是线粒体内过程、去乙酰酶和PARP的辅因子,NMN已经在动物模型中作为潜在的神经保护和抗衰老剂而被研究[3][4]。膳食补充剂公司积极推销NMN产品,宣传这些好处。[5]日本东京新宿庆应义塾大学医学院最近的一项人体研究表明,不超过500毫克的NMN剂量对男性是安全的。[6]
烟酰胺核苷(NR)激酶对NR和NMN的外源性利用至关重要。[7][8] 当外源性给药时,NMN必须转化为NR才能进入细胞并被重新磷酸化回NMN。NR和NMN都易受CD38环ADP核糖水解酶的胞外降解[8],而CD38酶可被CD38- in -78c.等化合物抑制[9]。
