Boise State University Theses and Dissertations
Veratrum californicum, commonly referred to as corn lily or Californian false hellebore, grows in high mountain meadows and produces bioactive steroidal alkaloids, including cyclopamine. Cyclopamine is a potent inhibitor of the Hedgehog (Hh) signaling pathway. Our lab has optimized methods to extract cyclopamine and related steroidal alkaloids from V. californicum, and implemented in-house Hh signaling bioactivity evaluation of these steroidal alkaloids using a Shh-Light II cell assay. A survey of extraction methods and solvents resulted in the identification of conditions most favorable for alkaloid extraction yield and antagonist activity in the Shh-Light II cell assay. The highest amount …
