Phosphonate inhibitors of antigen 85C, a crucial enzyme involved in the biosynthesis of the Mycobacterium tuberculosis cell wall

Bioorg Med Chem Lett. 2004 Jul 5;14(13):3559-62. doi: 10.1016/j.bmcl.2004.04.052.

Abstract

The first phosphonate inhibitors of antigen 85C--a major protein component of the Mycobacterium tuberculosis cell wall possessing mycolyltransferase activity were prepared using structure-based design. These potential novel antituberculosis agents, consisting of a phosphonate moiety, hydrophobic alkyl chain and a simple trehalose-mimicking aromatic structure, were designed as tetrahedral transition-state analogue inhibitors of antigen 85C, which catalyzes the key mycolyltransferase reaction involved in cell wall biosynthesis.
