AbstractUDP‐galactopyranose mutase (UGM) catalyzes the isomerization of UDP‐galactopyranose (UDP‐Galp) into UDP‐galactofuranose (UDP‐Galf), an essential step of the mycobacterial cell wall biosynthesis. In order to probe the UGM binding pocket, we synthesized the α‐ and β‐C‐glycosidic analogues of UDP‐galacopyranose along with the corresponding UDP‐exo‐galactal. Preliminary inhibition evaluation indicated that UDP‐exo‐galactal inhibits UGM with a binding affinity similar to that of UDP‐α‐C‐galactopyranose.(© Wiley‐VCH Verlag GmbH & Co.
