    A series of 2-amino-pyrazolopyridines was designed and synthesized as Polo-like kinase (Plk) inhibitors based on a low micromolar hit. The SAR was developed to provide compounds exhibiting low nanomolar inhibitory activity of Plk1; the phenotype of treated cells is consistent with Plk1 inhibition. A co-crystal structure of one of these compounds with zPlk1 confirms an ATP-competitive binding mode.
