Description: Cyclopamine, also known as 11-deoxojervine, is a naturally occurring chemical that belongs to the group of steroidal jerveratrum alkaloids. It is a teratogen isolated from the corn lily (Veratrum californicum) that causes usually fatal birth defects. It can prevent the fetal brain from dividing into two lobes (holoprosencephaly) and cause the development of a single eye (cyclopia). It does so by inhibiting the hedgehog signaling pathway (Hh). Cyclopamine is useful in studying the role of Hh in normal development, and as a potential treatment for certain cancers in which Hh is overexpressed. Cyclopamine was named for one-eyed lambs which were born to sheep which grazed on wild corn lily at a farm in Idaho.

| In vitro activity: | Finally, cyclopamine also significantly improved the tumor growth inhibition effect of i.v.-injected nanotherapeutics in pancreatic tumor xenograft mouse models. Reference: Biomaterials. 2016 Oct;103:12-21. https://pubmed.ncbi.nlm.nih.gov/27376555/ |
| In vivo activity: | The number of apoptotic cells in the BPH and cyclopamine rat groups were significantly reduced compared with the control group (P<0.05). Conversely, the number of apoptotic cells in the cyclopamine group was significantly increased (P<0.05) than that of the BPH group. These results suggested that cyclopamine could induce the apoptosis of epithelial cells in BPH rats.

Cyclopamine is currently being investigated as a treatment agent in basal cell carcinoma, medulloblastoma, and rhabdomyosarcoma, tumors that result from excessive Hh activity, glioblastoma, and as a treatment agent for multiple myeloma. Studies suggest that cyclopamine acts as a primary inhibitor of the so-called "hedgehog" signal-transduction pathway in cells. This pathway named for the ligand for the signal protein, is used by cells to help them react to external chemical signals. The pathway carries out important functions in embryonic development and when it goes awry, deformities can occur. However, errant activation of the pathway can also trigger cancer in adult humans, leading to basal cell carcinoma, medulloblastoma, rhabdomyosarcoma, and prostate, pancreatic and breast cancers. A way of controlling the pathway using cyclopamine could turn this problem on its head and provide a way to treat cancer. Many anticancer drugs are paradoxically carcinogenic in healthy individuals. The cyclopamine derivative IPI-926 is in clinical trials for the treatment of various types of cancer. [source: http://en.wikipedia.org/wiki/Cyclopamine).
