Lipopolysaccharide (LPS) and inflammatory cytokines cause activation of sphingomyelinases (SMases) and subsequent hydrolysis of sphingomyelin (SM) to produce a lipid messenger ceramide. The design of SMase inhibitors may offer new therapies for the t

9-(5′,5′-Difluoro-5′-phosphonopentyl)guanine (DFPP-G) and its hypoxanthine analogue (DFPP-H) were modified by introducing a methyl group to all possible positions of the linker connecting a purine and difluoromethylenephosphonic acid moiety to

Phosphonic acid analogues of acylcarnitine were prepared in an optically active form expecting CPT I inhibitory activities. The synthetic methodology was based on catalytic asymmetric dihydroxylation of β,γ-unsaturated phosphonates and subsequent r

An alternative synthesis of 1,3-propanediol 1 having a diethoxyphosphoryldifluoroethyl group was examined. The method readily provided a multi-gram quantity of 1. The propanediol 1 was chemo-enzymatically transformed to acyclic nucleotide analogues f

This paper covers recent publications from our laboratory on the synthesis of a variety of phosphonate and phosphinate derivatives. New methods for the enantioselective synthesis of alpha-hydroxyphosphonates were established by Lewis acid-mediated cl

γ-Amino-β-hydroxyphosphonates, useful intermediates for the synthesis of phosphonic acid analogues of carnitine, were prepared as their protected derivatives in an enantioselective manner from β,γ-unsaturated phosphonatesthrough asymmetric dihydr

Purine-nucleoside phosphorylase (PNP) deficiency in humans leads to inhibition of the T-cell response. Potent membrane-permeable inhibitors of this enzyme are therefore considered to be potential immunosuppressive agents. The binary complex of the tr

A synthetic approach to a new type of acyclic nucleotide analogues 8 and 9 was examined. The design was based on acyclic modification of MRS 2179, a P2Y 1 -antagonist, and replacement of one of two phosphate groups characterized by MRS 2179 with an i
