Inspired by DNA lesions produced by antitumor agents that inactivate Pol β, we have undertaken the development of covalent small-molecule inhibitors of this enzyme. Using a two-stage process involving chemically synthesized libraries, we identified a potent irreversible inhibitor (14) of Pol β (KI = 1.8 ± 0.45 μM, kinact
