Two kinds of inhibitors of the PLP-dependent enzyme sphingosine-1-phosphate lyase have been designed and tested on the bacterial (StS1PL) and the human (hS1PL) enzymes. Amino phosphates 1, 12, and 32, mimicking the intermediate aldimines of the catalytic process, were weak inhibitors on both enzyme sources. On the other hand, a series of stereodefined azido phosphates, resulting from the replacement of the amino group of the natural substrates with an azido group, afforded competitive inhibitors in the low micromolar range on both enzyme sources. This similar behavior represents an experimental evidence of the reported structural similarities for both enzymes at their active site level. Interestingly, the anti-isomers of the non-natural enantiomeric series where the most potent inhibitors on hS1PL.
Efficient synthesis of enantiomerically pure 2-acylaziridines: Facile syntheses of N-Boc-safingol, N-Boc-D-erythro-sphinganine, and N-Boc-spisulosine from a common intermediate

Various enantiomerically pure 2-acylaziridines were prepared efficiently from the corresponding aziridine-2-carboxylate via Weinreb's amide and the subsequent treatment of organometallic compounds. The carbonyl group of those 2-acylaziridines was stereose

Symbioramide was synthesized from D-erythro-dihydrosphingosine (19) and (R,E)-2'-tert-butyldimethylsilyloxy-3'-octadecenoic acid (14), which was prepared from (E)-2-octadecen-1-ol (4) by employing the Sharpless asymmetric epoxidation.The (2S,2'S,3R,3'E)-isomer 28 of 1 was also synthesized to further confirm the structure of 1. - Key Words: Ca(++)-ATPase activator / Ceramides / Marine natural products / Sphingosines / Symbioramide
