Cyclopamine

CAS No. : 4449-51-8

MCE 站：Cyclopamine

产品活性：Cyclopamine 是 Hedgehog 通路的拮抗剂，在细胞实验中的 IC₅₀ 为 46 nM。Cyclopamine 还是一种选择性的 Smo 抑制剂。

研究领域：Stem Cell/Wnt  |  Metabolic Enzyme/Protease

作用靶点：Hedgehog  |  Smo  |  Endogenous Metabolite

In Vitro: Treatment with small molecule Hh inhibitors such as HhAntag and the natural product Cyclopamine, both binding to Smo, induces tumor remission in a genetic mouse model of medulloblastoma. Cyclopamine is a Hedgehog (Hh) pathway antagonist. Cyclopamine suppresses cell growth. Cyclopamine (3 μM) suppression of Hh pathway activity and growth in digestive tract tumour cell lines correlates with expression of PTCHmRNA. Cyclopamine is a steroidal alkaloid that inhibits Hh signalling through direct interaction with Smo.

In Vivo: Cyclopamine causes durable regression of xenograft tumors. Tumors in Cyclopamine-treated animals, regress completely by 12 days. Cyclopamine (1.2 mg) treatment blocks tumour formation of human pancreatic adenocarcinoma cells after transplantation into nude mice.
