Design, synthesis, and structure-activity-relationship of phenyl imidazoles as potent Smoothened antagonists

Bioorg Med Chem Lett. 2012 Nov 1;22(21):6573-6. doi: 10.1016/j.bmcl.2012.09.013. Epub 2012 Sep 13.

Abstract

Through scaffold morphing of a known Smoothened antagonist Antag691, a series of novel phenyl imidazole derivatives were developed. Structure-activity-relationship studies and lead optimization led to the discovery of potent, selective and orally bioavailable Smoothened antagonist 19 that is suitable for in vivo studies.
