Merck, 239803-1MG, Cyclopamine, V. californicum

General description
A cell-permeable steroidal alkaloid and cholesterol mimic that displays both teratogenic and antitumor activities. It disrupts cholesterol bio-synthesis and specifically antagonizes shh (Sonic Hedgehog) signaling pathway through direct interaction with Smo (smoothened), a distant relative of G-protein-coupled receptors. A valuable tool for studying the involvement of shh signaling in the development of various tumors. Tomatidine can be used as a negative control. Also available as a 10 mM solution in Ethanol (Cat. No. 239806).
Cyclopamine, V. californicum, CAS 4449-51-8, is a cell-permeable steroidal alkaloid & cholesterol mimic that specifically antagonizes Sonic Hedgehog signaling through direct interaction with Smo.
