Honor recognizes groundbreaking work in Biomedical Sciences

Located on Busch Campus of Rutgers, The State University of New Jersey, the Waksman Institute of Microbiology is an interdisciplinary research institute devoted to excellence in basic research. Focus areas include developmental biology, cell biology, biochemistry, structural biology, genetics, and genomics.

To support the educational mission of Rutgers, Waksman faculty members hold appointments in academic departments throughout the university. Our researchers train undergraduate students, graduate students, and post-doctoral fellows, as well as engage high school students in research through an outreach program.

CBR hydroxamidines are small-molecule inhibitors of bacterial RNA polymerase (RNAP) discovered through high-throughput screening of synthetic-compound libraries. CBR pyrazoles are structurally related RNAP inhibitors discovered through scaffold hopping from CBR hydroxamidines. CBR hydroxamidines and pyrazoles selectively inhibit Gram-negative bacterial RNAP and exhibit selective antibacterial activity against Gram-negative bacteria. Here, we report crystal structures of the prototype CBR hydroxamidine, CBR703, and a CBR pyrazole in complex with E. coli RNAP holoenzyme. In addition, we define the full resistance determinant for CBR703, show that the binding site and resistance determinant for CBR703 do not overlap the binding sites and resistance determinants of other characterized RNAP inhibitors, show that CBR703 exhibits no or minimal cross-resistance with other characterized RNAP inhibitors, and show that co-administration of CBR703 with other RNAP inhibitors results in additive antibacterial activities. The results set the stage for structure-based optimization of CBR inhibitors as antibacterial drugs.
