accumulation of psychosine (galactosyl sphingosine) has been associated with the pathogenesis of Krabbe disease, however, the exact mechanism of its cytotoxicity remains unclear. Herein, we describe the synthesis of the unnaturalenantiomer of erythrosphingosine, psychosine, and related derivatives thereof that would allow for the mechanistic elucidation of the toxicity of psychosine.

to the gram scale synthesis of an aryloxy amidate prodrug of phosphonomethoxydeoxythreosyl adenine. This prodrug exerted potent activity against an entecavir-resistant hepatitis B virus (HBV) strain, while leading to a significant reduction in the levels of HBV covalently closed circular DNA in a cellular assay. Furthermore, its remarkable anti-HBV efficacy was also confirmed in vivo using a hydrodynamic
