The availability of high quality probes for specific protein targets is fundamental to the investigation of their function and their validation as therapeutic targets. We report the utilization of a dedicated chemoproteomic assay platform combining affinity enrichment technology with high resolution protein mass spectrometry to the discovery of a novel nicotinamide isoster, the tetrazoloquinoxaline 41, a highly potent and selective tankyrase inhibitor. We also describe the use of 41 to investigate the biology of tankyrase, revealing the compound induced growth inhibition of a number of tumor derived cell lines, demonstrating the potential of tankyrase inhibitors in oncology.
