Abstract:

We have designed, synthesized, and evaluated 5-benzylidenerhodanine- and 5-benzylidenethiazolidine-2,4-dione-based compounds as inhibitors of bacterial enzyme MurD with E. coli IC(50) in the range 45-206 muM. The high-resolution crystal structure of MurD in complex with (R,Z)-2-(3-[{4-([2,4-dioxothiazolidin-5-ylidene]methyl)phenylamino}methyl) benzamido)pentanedioic acid [(R)-32] revealed details of the binding mode of the inhibitor within the active site and provides a good foundation for structure-based design of a novel generation of MurD inhibitors.
