PF-5274857 is a potent, orally active and selective inhibitor of hedgehog (Hh) signalingpathway (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
Jervine is a naturally occurring steroidal alkaloid derived from the Veratrum plant species. Over the Hedgehogsignalingpathway, Jervine effectively inhibits tumor growth using three human tumor xenograft models. Jervine has the potential to advance to t
HPI-1 (hydrate) is a Hedgehog (Hh) pathway inhibitor that suppresses signaling through Sonic Hh (IC50= 1.5 μM) without significantly affecting Wnt signaling (IC50≥ 30 μM).1HPI-1 suppresses Hh activation induced by loss of Suppressor of Fused or by Gli overexpression, suggesting action at posttranslational modification of Gli protein or at the interaction of Gli with a co-factor.1HPI-1 (hydrate) also inhibits signaling through the oncogenic Smoothened (Smo) mutant SmoM2 in neuron precursors, preventing cell proliferation.1 1.Hyman, J.M., Firestone, A.J., Heine, V.M., et al.Small-molecule inhibitors reveal multiple strategies for Hedgehogpathway blockadeProceedings of the National Academy of Sciences of the United States of America106(33)14132-14137(2009)
Potent fluorescent Smo antagonist (IC50 = 100 nM). Non-fluorescent analog also available. Fan et al (2014) The Hedgehogpathway effector smoothened exhibits signaling competency in the absence of ciliary accumulation. Chem.Biol. 21 1680 PMID:25484239
MRT-83 (hydrochloride) is a potent antagonist of the Smoothened (Smo) receptor, effectively inhibiting the Hedgehog (Hh) signalingpathway and BODIPY-cyclopamine binding to human Smo. With its potential applications in the study of cancer disease, MRT-83 (hydrochloride) demonstrates promising prospects for research purposes.
