Description of PF-5274857

PF-5274857 is an inhibitor of hedgehog (Hh) signaling pathway and is identified as a potent and selective antagonist of Smoothened (Smo) with an IC50 of 5.8 nM.

Smoothened, a G protein-coupled receptor, is a component of the hedgehog signaling pathway and is conserved from flies to humans. This protein is the molecular target of the teratogen cyclopamine. SMO can act as an oncogene and the activation of SMO mutations leads to unregulated activation of the hedgehog pathway and cancer.

In MEF cells, treatment of PF-5274857 completely blocked Shh-induced Hh pathway activity, which was measured by the transcriptional activity of Smo downstream gene Gli1.

In vivo, PF-5274857 showed anti-tumor activity in a mouse medulloblastoma model with IC50 of 8.9 nM. PF-5274857 also shows significant dose-dependent tumor growth inhibition (TGI) and induces tumor regression. In skin tissue, downregulation of Gli1 and Gli2 is also observed with a similar time course by PF-52748571.

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
