Compounds which inhibit microbial growth or attenuate the virulence of pathogen microorganisms. Compounds of the invention inhibit UDP-galactopyranose mutase (UGM) and have activity as inhibitors of microbial growth of microorganisms which contain this enzyme and particularly those microorganisms in which this enzyme is responsible for the incorporation of galactofuranose residues, particularly for uridine 5′-diphosphate (UDP) galactopyranose mutase. Compounds of the invention inhibit UDP-galactopyranose mutase (UGM) and have activity to attenuate virulence of pathogenic microorganisms, including mycobacteria.

UDP-Galactopyranose mutase (UGM or Glf), which catalyzes the interconversion of UDP-galactopyranose and UDP-galactofuranose, is implicated in the viability and virulence of multiple pathogenic microorganisms. Here we report the synthesis of high-affinity ligands for UGM homologues from Klebsiella pneumoniae and Mycobacterium tuberculosis. The potency of these compounds stems from their ability to access both the substrate binding pocket and an adjacent site.

Galactofuranose (Galf) residues are fundamental components of the cell wall of mycobacteria. A key enzyme, UDP-galactopyranose mutase (UGM), that participates in Galf incorporation mediates isomerization of UDP-Galf from UDP-galactopyranose (UDP-Galp). UGM is of special interest as a therapeutic target because the gene encoding it is essential for mycobacterial viability and there is no comparable enzyme in humans. We used structure-activity relationships and molecular design to devise UGM inhibitors. From a focused library of synthetic aminothiazoles, several compounds that block the UGM from Klebsiella pneumoniae or Mycobacterium tuberculosis were identified. These inhibitors block the growth of M. smegmatis.
