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 0.050nM. 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.
