Cyclopamine 是Hedgehog通路的拮抗劑，細胞實(shí)驗中IC50=46 nM。它還是選擇性Smo抑制劑。

環(huán)巴胺的EC50是10.57微米，這是通過(guò)FXR-bla(法尼基X受體-β-內酰胺酶)分析確定的[3]。 Hh信號通路在胚胎發(fā)育和腫瘤發(fā)生中起著(zhù)關(guān)鍵作用[4]。Hh信號通路在廣泛的人類(lèi)組織中顯示出調節細胞增殖和分化的顯著(zhù)性。它與許多人類(lèi)惡性腫瘤中的異常細胞存活有關(guān)，從基底細胞癌和髓母細胞瘤到小細胞肺、胃腸道、乳腺和前列腺腫瘤[1]。

暴露于環(huán)巴胺的胚胎導致可見(jiàn)的外部缺陷，包括獨眼畸形、長(cháng)鼻形成、小眼癥、胸部前凸、阿米莉亞和體型減小。對胃腸器官的檢查顯示了嚴重的缺陷，包括腸管長(cháng)度縮短和前腸衍生器官中的間充質(zhì)細胞數量減少。在十二指腸、胃和背胰腺中也發(fā)現了異位結構[5]。
