of beta-nicotinamide riboside and a series of related amide, ester, and acid nucleosides. Compounds were prepared through a triacetylated-nicotinate ester nucleoside, via coupling of either ethylnicotinate or phenylnicotinate with 1,2,3,5-tetra-O-acetyl-beta-D-ribofuranose. Nicotinamide riboside, nicotinic acid riboside, O-ethylnicotinate riboside, O-methylnicotinate riboside, and several N-alkyl derivatives
一种新的两步法可实现β-烟酰胺核糖和一系列相关酰胺,酯和酸核苷的立体选择性合成。通过三乙酰化烟酸酯酯核苷,通过将烟酸酯或烟酸酯与1,2,3,5-四-O-乙酰基-β-D-呋喃呋喃糖偶联来制备化合物。烟酰胺核糖,烟酸核糖,邻乙基烟酸核糖,邻甲基烟酸核糖和几种N-烷基衍生物在几种哺乳动物细胞系中使NAD +的浓度从1.2-2.7倍增加。这些发现建立了这些核苷在刺激哺乳动物细胞中NAD +浓度增加方面的生物利用度和有效作用。
