benzyloxyalkyl-substituted 1,2,3-triazolyl α-GalCeranalogues are reported. The novel α-GalCeranalogues activate invariant natural killer T (iNKT) cells via CD1d mediated presentation, which was confirmed by in vitro tests performed on iNKT hybridomas incubated with CD1d proteins. When tested on isolated murine splenocytes, the T1204B and T1206B compounds stimulated higher levels of both IFN-γ and IL-4 cytokine

A facilesynthesis of D-ribo-C18-Phytosphingosine from divinylcarbinol via Sharpless asymmetric epoxidation and Sharpless asymmetric dihydroxylation was described.
A highly convergent synthetic approach was developed to obtain alpha-galactosyl cerebroside O-(alpha-D-galactopyranosyl)-2-hexacosylamino-D-ribo-1,3,4-octa decantriol, which has previously been demonstrated to have immunostimulatory activity. Known 4,6-O-benzylidene galactose was the starting material for both the required alpha-galactosyl and the phytosphingosine building blocks O-(2,3-di-O-benzyl-4
