Identification
Common NameCyclopamine
ClassSmall Molecule
DescriptionCyclopamine 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.

Toxicity Profile
Route of ExposureNot Available
Mechanism of ToxicityCyclopamine 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 pathway (Hh). Cyclopamine inhibits the Hh by influencing the balance between the active and inactive forms of the smoothened protein. 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 acts as a primary inhibitor of the hedgehog signaling 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. (Wikipedia) Cyclopamine inhibits the Hh pathway by binding to and preventing the activation of Smoothened (Smo), preventing downstream target gene regulation. (1)

Targets

General Function:
Wnt-protein binding
Specific Function:
G protein-coupled receptor that probably associates with the patched protein (PTCH) to transduce the hedgehog's proteins signal. Binding of sonic hedgehog (SHH) to its receptor patched is thought to prevent normal inhibition by patched of smoothened (SMO). Required for the accumulation of KIF7 and GLI3 in the cilia.

General Function:
Zinc ion binding
Specific Function:
Intercellular signal essential for a variety of patterning events during development: signal produced by the notochord that induces ventral cell fate in the neural tube and somites, and the polarizing signal for patterning of the anterior-posterior axis of the developing limb bud. Displays both floor plate- and motor neuron-inducing activity. The threshold concentration of N-product required for motor neuron induction is 5-fold lower than that required for floor plate induction. Activates the transcription of target genes by interacting with its receptor PTCH1 to prevent normal inhibition by PTCH1 on the constitutive signaling activity of SMO (By similarity).
