Abstract

Nicotinamide adenine dinucleotide (NAD) analogues inhibit the NADase activity of CD38. In the current study, efficient protocols for the synthesis of substituted-nicotinamide nucleosides and nucleotides were developed. The one-pot phosphorylation–esterification strategy provides a convenient way of obtaining nicotinamide nucleoside phosphodiesters from the corresponding nucleosides. Structure–activity relationship information revealed that replacement of 3’-hydroxy group with F or N3 led to the considerably decrease of activity as compared with ara-F NMN. Phosphodiesterification of nicotinamide nucleosides lowers their inhibitory activities in some extent.
