competitive CST inhibitors, we synthesised and investigated analogues of the substrate galactosylceramide with variations at the anomeric position, the acyl substituent and the carbohydrate moiety, and investigated their structure–activity relationships. While most of the compounds behaved as substrates, α-galactosylceramide 16 was identified as the first competitive CST inhibitor. Compound 16 can

The present invention relates to a nervonic acid derivatives of formula (I)
CH3—(CH2)7—CH═CH—(CH2)13—C(O)—O—(CH2)3—OR (I)
wherein R is hydrogen (H) or a residue of a carboxylic acid; or a salt of the compound where R is H; or a bioprecursor, prodrug thereof. Those compounds wherein R is other than H have pharmacological activity, in particular anti-inflammatory and immunomodulatory effects. Those compounds wherein R is H can be used to prepare the pharmacologically active derivatives.
An efficient, one-pot procedure for the synthesis of ceramide 1-phosphates with varying N-acyl substituents, to serve as tool compounds for analytical and biological investigations, was developed. Sphingosine 1-phosphate was silylated in situ to increase its solubility and to protect the 3-hydroxy functionality and then allowed to react with activated acid derivatives in the presence of diisopropylethylamine

A concise route to the 6-azido-6-deoxy-alpha-galactosyl-phytosphingosine derivative 9 is reported. Orthogonal protection of the two amino groups allows elaboration of 9 into a range of 6-N-derivatized alpha-galactosyl ceramides by late-stage introduction of the acyl chain of the ceramide and the 6-N-group in the sugar headgroup. Biologically active glycolipids 6 and 8 have been synthesized to illustrate the applicability of the approach.
