| Description | Purmorphamine is a blocker of BODIPY-cyclopamine binding to Smo with IC50 of ~ 1.5 μM and also is an inducer of osteoblast differentiation with EC50 of 1 μM. | |||||
| Targets | Smoothened (Smo) | |||||
| IC50 | 46 nM | |||||
| Cell experiment: [1] | |
|
Cell lines |
AA/C1, RG/C2, CaCo2, HT29 and SW480 cells |
|
Preparation method |
The solubility of this compound in DMSO is <10 mM. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while.Stock solution can be stored below -20°C for several months. |
|
Reaction Conditions |
20 μM, 48 hours for cell yield inhibition 10 μM, 48 hours for apoptosis induction (measured by PARP expression) |
|
Applications |
Treatment of cyclopamine significantly reduced cell yield in all the tested human colorectal tumour cell lines with a dose-dependent manner. Cyclopamine also remarkably induced apoptosis in each of the cell lines. The CaCo2 cell line showed particular sensitivity to cyclopamine-induced apoptosis. |
| Animal experiment: [2] | |
|
Animal models |
C57BL/6J mice |
|
Dosage form |
Intraperitoneal injection, 160 mg/kg/day for 31 hours. |
|
Applications |
Cyclopamine showed teratogenic potential in the tested animals. Affected embryos were slightly smaller than normal littermates and exhibited mild blunting of the snout as well as cleft lip and palate. Embryos exhibited unilateral and bilateral complete cleft lip with clefts extending into the primary and secondary palate. Facial clefts were often accompanied by open eyelid defects and in one embryo by forelimb syndactyly. |
|
Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |

Cyclopamine is a naturally occurring Hedgehog (Hh)?specific small?molecule signaling steroidal alkaloid inhibitor, causes a profound inhibition of tumor growth, has significant anti?invasive, anti?proliferative and anti?estrogenic potency in human breast cancer cells [2] [1]. The EC50 of cyclopamine is 10.57 μM, it was identified by an FXR-bla (farnesoid X receptor- b-lactamase) assay [3].
Hh signaling pathway plays a critical role in embryonic development and tumorigenesis [4]. Hh signaling pathway shows saliency in regulating cellular proliferation and differentiation in a wide array of human tissues. It is related to aberrant cell survival in numerous human malignancies, ranging from BCCs and medulloblastomas to small cell lung, gastrointestinal, breast and prostate tumors [1].
Treated with cyclopamine (10 or 20 μM) only and incubated for time periods ranging from 0 to10 days, MCF-7 cells and MDA?MB?231 cells displayed a significant reduction in proliferation rate compared with the control cells on days 3 and 6 (P<0.01). In the MCF?7 cells, cyclopamine significantly induced cell accumulation in the G1 phase (P<0.01) and a modest decrease in the S population percentage, from 22 to 16% (P<0.01). In the MDA?MB?231 cells, cyclopamine caused a significant increase in G1 cells. The invasion rate of cyclopamine?treated MCF?7 and MDA?MB?231cells significantly decreased compared with the CK [2].
Embryoes exposed to cyclopamine resulted in visible external defects, including cyclopia, proboscis formation, microphthalmia, thoracic lordosis, amelia and decreased body size. Examination of gastrointestinal organs revealed severe deficits, including less length of the gut tube and mesenchymal cell numbers in foregut-derived organs. Ectopic structures in duodenum, stomach, and dorsal pancreas were also found [5].
