A potent, cell-permeable analog of Cyclopamine that specifically inhibits the Hedgehog (Hh) signaling with similar or lower toxicity (IC50 = 20nM in Shh-LIGHT2 assay; 50nM in p2Ptch-/-cells; 500nM in SmoA1-LIGHT cells). Binds to SmoA1 and promotes its exit from the endoplasmic reticulum. Suppresses both the ShhNp-induced pathway activity and SmoA1-induced reporter activity. Shown to sensitize human glioma cells to TRAIL-induced apoptosis.Formula:C44H63N3O4Primary Target:Hh signaling in Shh-light2 assayPrimary Target IC50:20nMSecondary Target:in P2Ptch-/-cells (IC50 = 50nM)Solubility:DMSO, EtOH, or MeOHMolecular Weight:698Storage and Stability:Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile buffer or dH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
