Potent Ligands for Prokaryotic UDP-Galactopyranose Mutase That Exploit an Enzyme Subsite
摘要:
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.

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.

The synthesis and pharmacological testing of a series of non-peptidic blockers of the SK(Ca) (SK-3) channel is described. Target compounds were designed to mimic the spatial relationships of selected key residues in the energy-minimised structure of the octadecapeptide apamin, which are a highly potent blocker of this channel. Structures consist of a central unit, either a fumaric acid or an aromatic
