Orthosteric inhibitors of the human heterodimeric DNA mismatch repair complex MutSbeta were identified by high-throughput screening. Following extensive hit confirmation to remove false positives, two series were found to give consistent activity free of likely artefactual effects. Extensive hit profiling confirmed an ATP-competitive mode of action, and X-ray crystallography showed the inhibitors occupying the ATP-binding site of MSH3.
