We have developed a screening assay by thin-layer chromatography (TLC) to identify inhibitors for the bacterial essential enzymes MurA, -B, and -C. Libraries of compounds were synthesized using the mix-and-split combinatorial chemistry approach. Screening of the pooled compounds using the developed assay revealed the presence of many pools active in vitro. Pools of interest were tested for antibacterial activity. Individual molecules in the active pools were synthesized and retested with the TLC assay and with bacteria. We focused on the best five compounds for further analysis. They were tested for inhibition on each of the three enzymes separately, and showed no inhibition of MurA or MurB activity but were all inhibitors of MurC enzyme. This approach yielded interesting lead compounds for the development of novel antibacterial agents.
