Bioorg Med Chem Lett. 2011 Mar 15;21(6):1896-9. doi: 10.1016/j.bmcl.2010.11.003. Epub 2010 Dec 21.

Abstract

The neurokinin-3 (NK3) receptor is regarded as a potential novel target for treating patients with schizophrenia. Herein we report the synthesis and SAR of a series of C3-alkylsulfoxide substituted quinolines as potent NK3 receptor antagonists. These compounds have excellent NK3 functional activity, good selectivity and drug-like properties. Several key compounds have good in vitro/in vivo DMPK characteristics, and are active in a gerbil locomotor activity model.
