Introduction of fluorine to phenyl group of 4-(2-pyrimidinylamino)benzamides leading to a series of potent hedgehog signaling pathway inhibitors

Add time:09/05/2019    Source:sciencedirect.com

In present study, a novel series of fluorine containing 4-(2-pyrimidinylamino)benzamide analogues were designed and synthesized. The hedgehog (Hh) signaling inhibitory activities for these compounds were evaluated by a luciferase reporter method. The preliminary SAR was discussed and many compounds showed potent Hh signaling inhibitory activities. Compound 15h displayed the most potent inhibitory activity, with an IC50 of 0.050 nM. This paper finds the introduction of fluorine to the 4-(2-pyrimidinylamino)benzamide scaffold can lead to a novel series of potent Hh signaling pathway inhibitors.
