    Using structure-based design, a novel series of pyridone ERK1/2 inhibitors was developed. Optimization led to the identification of (S)-14k, a potent, selective, and orally bioavailable agent that inhibited tumor growth in mouse xenograft models. On the basis of its in vivo efficacy and preliminary safety profiles, (S)-14k was selected for further preclinical evaluation.
