Abstract:

A series of carbamate-containing sialyltransferase inhibitors were designed and synthesized to simulate phosphate-linkedCMP-Neu5Ac. Their inhibitory activities were assayed against recombinant human ST3Gal I and ST6Gal I by using the Schmidt’sHPLC-based assay. The synthetic compound 15g showed moderate inhibitory activity. These findings implied that carbamate might serve as a bioisosteric replacement for a phosphate group in sialyltransferase inhibitor design to improve the membrane permeability.
