5.4.99.9 | (2S)-2-deoxy-2-selenonium-2-[(2S,3S,4R,5S)-2,3,4,5,6-pentahydroxyhexyl]-D-arabinitol chloride | a transition-state analogue, shows about 25% inhibition at 0.5 mm | Mycobacterium tuberculosis | |
5.4.99.9 | (2S)-2-deoxy-2-sulfonium-2-[(2S,3S,4R,5S)-2,3,4,5,6-pentahydroxyhexyl]-D-arabinitol chloride | a transition-state analogue, shows about 25% inhibition at 0.5 mm | Mycobacterium tuberculosis | |
5.4.99.9 | additional information | synthesis of a sulfonium and selenonium ion with an appended polyhydroxylated side chain. The compounds are designed as transition state mimics of the UGM-catalyzed reaction, where the head groups carrying a permanent positive charge, and are designed to mimic both the shape and positive charge of the proposed galactopyranosyl cation-like transition state, HPLC-based UGM inhibition assay. Even modifying one of these inhibitors by attaching the uridine monophosphate (UMP) fragment via an alpha-linkage to the 1,4-dideoxy-1,4-imino-D-galctitol moiety using a three-carbon linker does not improve the inhibitory profile significantly.

5.4.99.9 | physiological function | UDP-galactopyranose mutase (UGM), an enzyme found in many eukaryotic and prokaryotic human pathogens, catalyzes the interconversion of UDP-galactopyranose (UDP-Galp) and UDPgalactofuranose (UDP-Galf), the latter being used as the biosynthetic precursor of the galactofuranose polymer portion of the mycobacterium cell wall | Mycobacterium tuberculosis |
