    Potent and selective inhibitors of tankyrases have recently been characterized to bind to an induced pocket. Here we report the identification of a novel potent and selective tankyrase inhibitor that binds to both the nicotinamide pocket and the induced pocket. The crystal structure of human TNKS1 in complex with this "dual-binder" provides a molecular basis for their strong and specific interactions and suggests clues for the further development of tankyrase inhibitors.
