3-amido-4-anilinoquinolines as CSF-1R kinase inhibitors 2: Optimization of the PK profile

Bioorg Med Chem Lett. 2009 Feb 1;19(3):701-5. doi: 10.1016/j.bmcl.2008.12.044. Epub 2008 Dec 14.

Abstract

The optimization of compounds from the 3-amido-4-anilinoquinolines series of CSF-1R kinase inhibitors is described. The series has excellent activity and kinase selectivity. Excellent physical properties and rodent PK profiles were achieved through the introduction of cyclic amines at the quinoline 6-position. Compounds with good activity in a mouse PD model measuring inhibition of pCSF-1R were identified.
