Small-molecule drug discovery for cancer therapy is making extraordinary progress within the realm of advancing novel oncogenic protein kinase inhibitor lead compounds of significant impact to both basic research and clinical testing. In this perspective, structure- and mechanism-based drug design are highlighted relative to such progress. Also, evolving concepts in novel oncogenic protein kinase inhibitor drug discovery is highlighted relative to therapeutic target selectivity, including the recent identification of oncogenic kinase mutants effecting drug-resistance or enhanced drug susceptibility to small-molecule inhibitors.
