    Piperidine carboxamide 1 was identified as a novel inhibitor of anaplastic lymphoma kinase (ALK enzyme assay IC(50) = 0.174 μM) during high throughput screening, with selectivity over the related kinase insulin-like growth factor-1 (IGF1R). The X-ray cocrystal structure of 1 with the ALK kinase domain revealed an unusual DFG-shifted conformation, allowing access to an extended hydrophobic pocket. Structure-activity relationship (SAR) studies were focused on the rapid parallel optimization of both the right- and left-hand side of the molecule, culminating in molecules with improved potency and selectivity over IGF1R.
