Synthesis of a nitrogen analogue of sphingomyelin as a sphingomyelinase inhibitor.

Abstract

[structure: see text] Sphingomyelin nitrogen analogue 1 was designed and synthesized as a sphingomyelinase inhibitor. The synthesis was established by continuous Hofmann rearrangement and Crutius rearrangement as key steps in constructing the 3-hydroxy-1,2-diamine structure in the backbone of 1. This analogue showed moderate inhibitory activity toward SMase isolated from B. cereus.
