Scaffold-hopping with zwitterionic CCR3 antagonists: identification and optimisation of a series with good potency and pharmacokinetics leading to the discovery of AZ12436092

Bioorg Med Chem Lett. 2012 Nov 1;22(21):6694-9. doi: 10.1016/j.bmcl.2012.08.103. Epub 2012 Sep 11.

Abstract

The discovery and optimisation of a series of zwitterionic CCR3 antagonists is described. Optimisation of the structure led to AZ12436092, a compound with excellent selectivity over activity at hERG and outstanding pharmacokinetics in preclinical species.
