Sphingosine-1-phosphate (S1P) signaling plays a vital role in mitogenesis, cell migration and angiogenesis. Sphingosine kinases (SphKs) catalyze a key step in sphingomyelin metabolism that leads to the production of S1P. There are two isoforms of SphK and observations made with SphK deficient mice show the two isoforms can compensate for each other's loss. Thus, inhibition of both isoforms is likely required to block SphK dependent angiogenesis. A structure based approach was used to design and synthesize a series of SphK inhibitors resulting in the identification of the first potent inhibitors of both isoforms of human SphK. Additionally, to our knowledge, this series of inhibitors contains the only sufficiently potent inhibitors of murine SphK1 with suitable physico-chemical properties to pharmacologically interrogate the role of SphK1 in rodent models and to reproduce the phenotype of SphK1 (-/-) mice.

trans-4-Hydroxy-l-proline has been used as a starting material for the synthesis of prolinol-based nucleotide analogues with an N-phosphonomethyl moiety attached to the prolinol ring nitrogen atom. The synthetic methodology based on the inversion of configuration at both 1- and 4-position led to all diastereoisomeric O-protected 4-mesyloxyprolinol-N-phosphonates. Alkylation of nucleobases using the synthons in the l-series afforded the nucleotide analogues corresponding to α-l- and β-l-nucleotide. The NMR-based conformational study of these compounds in aqueous solution performed at two different pH values, showing either N-fully protonated or deprotonated forms, revealed the occurrence of the same mostly populated conformer in both cases. All final l-prolinol-based nucleoside phosphonic acids were tested for cytotoxic and antiviral properties, but no significant activity was found.

Modified oligonucleotides incorporating trans-4-hydroxy-N-acetyl-L-prolinol (trans-4-HO-L-NAP) or its D-analogue as sugar substitute were synthesised with adenine and thymine as nucleobases. All-adenine oligonucleotides built from (2S,4S) or (2R,4R)-cis-4
