NAD+类似物的合成及其性质研究

open access: yes, 2000
烟酰胺腺嘌呤二核苷酸(NAD+)依赖型脱氢酶是立体选择性还原碳氧双键制备手性化合物的重要生物催化剂,但因需要消耗化学计量的辅酶而受到限制。因此,创建基于NAD+类似物为辅酶的新型催化体系具有应用潜力和化学生物学价值。本论文致力于合成结构简单、相对稳定的新型NAD+类似物,研究辅酶类似物的性质,为建立新型生物催化体系和研究小分子与生物大分子相互作用奠定基础。 第一,建立了高效合成磷酸二酯型NAD+类似物的方法。以烟酰胺为原料,经多步化学转化,以69-93%的耦连产率合成了17种结构新颖的NAD+类似物 ...

NAD+ Metabolism and Signaling [PDF]

open access: yesCell Metabolism, 2019
We caught up with some of the leading researchers in the NAD+ metabolism and signaling field as they gathered in Dublin for the 2019 FASEB Science Research Conference. Here they share their excitement from the rich history of NAD+ biology dating back over 100 years ago to a future of translation benefiting human health and aging.
