Cyclopamine-KAAD - Calbiochem (C15-1301-520)

General description

A cell-permeable potent analog of Cyclopamine (Cat. No. 239803) that specifically inhibits 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 ShhNp-induced pathway activity and SmoA1-induced reporter activity. Reported to cause regression of murine tumor allografts in vivo and induce rapid cell death in human medulloblastoma. Shown to sensitize human glioma cells to TRAIL-induced apoptosis.
