Description

General description

A potent, cell-permeable analog of Cyclopamine (Cat. No. 239803) that specifically inhibits the Hedgehog (Hh) signaling with similar or lower toxicity (IC₅₀ = 20 nM in Shh-LIGHT2 assay; 50 nM in p2^Ptch-/-cells; 500 nM 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. Also available as a 1 mM solution in DMSO (Cat. No. 239807).
