pf-5274857 mesylate

PF-5274857 is a potent, orally active and selective inhibitor of hedgehog (Hh) signaling pathway (IC50 = 5.8 nM, Ki = 4.6 nM) . PF-5274857 effectively penetrates the blood-brain barrier and inhibits Smo activity in the brain of primary medulloblastoma mic

PF-5274857 hydrochloride is a potent, orally active, selective Smo antagonist (IC50=5.8 nM, Ki=4.6 nM) that is permeable through the blood-brain barrier. It has research potential in various tumors, including brain tumors and brain metastases driven by activated Hh pathways.

PF-5274857 (PF-5274857 free base) is an effective and selective hedgehog signaling pathway inhibitor (IC50: 5.8 nM and a Ki: 4.6 nM). PF-5274857 is a potentially attractive clinical candidate for the treatment of tumor types including brain tumors and brain metastasis driven by an activated Hh pathway.PF-5274857 was found to effectively penetrate the blood-brain barrier and inhibit Smo activity in the brain of primary medulloblastoma mice, resulting in improved animal survival rates. PF-5274857 was orally available and metabolically stable in vivo.
