Synthesis and pharmacological evaluation of trifluoromethyl containing 4-(2-pyrimidinylamino)benzamides as Hedgehog signaling pathway inhibitors

Add time:07/14/2019    Source:sciencedirect.com

In present study, a series of novel containing trifluoromethyl 4-(2-pyrimidinylamino)benzamide derivatives were designed by the fluorine scan strategy. Their Hh signaling inhibitory activities were evaluated by Gli-luciferase reporter method. The comprehensive SAR was discussed and several derivatives were found to display more potent Hh signaling inhibitory activity than positive drug vismodegib. Compound 13d was the most potent compound with IC50 of 1.44 nM against Hh signaling pathway and also exhibited optimal PK properties in the in vivo PK properties study, deserved as an ideal lead compound for further study in future.
