Bioorg Med Chem Lett. 2011 Aug 15;21(16):4698-701. doi: 10.1016/j.bmcl.2011.06.093. Epub 2011 Jun 29.

Abstract

We disclose a novel series of insulin-like growth factor-1 receptor kinase inhibitors based on the 3-(pyrimidin-4-yl)-imidazo[1,2-a]pyridine scaffold. The influence on the inhibitory activity of substitution on the imidazopyridine and at the C5 position of the pyrimidine is discussed. In the course of this optimization, we discovered a potent and selective inhibitor with suitable pharmacokinetics for oral administration.
