PhysalinK was isolated fromPhysalis alkekengi var. francheti. Spectroscopic studies and chemical correlations, however, revealed that the reported structure of physalinK at the AB ring moiety, namely, 4α,5α-epoxy-6α-hydroxy-2-en-1-one, should be revised to 2α,5α-epidioxy-6β-hydroxy-3-en-1-one. A newphysalin, named physalin Q, was also isolated and identified as the 2β,5β-epidioxy diastereomer of

The invention provides methods for modulating, e.g., antagonizing, the activity of the Hedgehog signaling pathway, and for treating Hedgehog related disorders such as cancers (e.g., medulloblastoma). In particular, the invention provides methods for inhibiting aberrant growth states resulting from phenotypes such as Ptch loss-of function, Hedgehog gain-of-function, smoothened gain-of-function or Gli gain-of-function by administering to a mammal combinations of Smoothened inhibitors (e.g., a compound of Formula I, Formula II, or Formula III, or any of the compounds listed herein or incorporated by reference) and Gli inhibitors, and/or Phosphatidylinositol 3-kinase (PI3K) inhibitors.
本发明提供了调节(如拮抗)刺猬信号通路活性的方法,以及治疗刺猬相关疾病如癌症(如髓母细胞瘤)的方法。特别是,本发明提供了通过向哺乳动物施用 Smoothened 抑制剂(例如,式 I、式 II 或式 III 的化合物,或本文所列或通过参考文献并入的任何化合物)和 Gli 抑制剂和/或磷脂酰肌醇 3- 激酶(PI3K)抑制剂的组合,抑制表型(如 Ptch 功能缺失、刺猬蛋白功能增益、smoothened 功能增益或 Gli 功能增益)导致的异常生长状态的方法。

One aspect of the invention relates to an in vitro method for obtaining hiPSC-derived sebocyte precursor cells comprising the steps of:
a) culturing, under feeder layer-free conditions, human induced pluripotent stem cells (hiPSC) in a sebocyte basal medium complemented with a combination of (i) retinoic acid (RA), (ii) bone morphogenetic protein 4 (BMP4) and (iii) epidermal growth factor (EGF), during a period of time ranging from about 5 days to about 15 days, so as to generate multipotent skin precursor cells,
b) culturing, under feeder layer-free conditions, the multipotent skin precursor cells obtained at step a) in a sebocyte differentiation basal medium, during a period of time ranging from about 5 days to about 15 days, so as to generate hiPSC-derived sebocyte precursor cells, and
c) collecting the hiPSC-derived sebocyte precursor cells obtained at step b).
本发明的一个方面涉及一种获得hiPSC衍生皮脂腺前体细胞的体外方法,包括以下步骤:
a) 在无饲养层条件下,在皮脂腺基础培养基中培养人诱导多能干细胞(hiPSC),该培养基由(i)视黄酸(RA)、(ii)骨形态发生蛋白4(BMP4)和(iii)表皮生长因子(EGF)组成,培养时间约为5天至15天,以产生多能皮肤前体细胞、
b) 在无饲养层的条件下,在皮脂细胞分化基础培养基中培养在步骤 a) 中获得的多能皮肤前体细胞,培养时间从约 5 天到约 15 天不等,以产生源于 hiPSC 的皮脂细胞前体细胞,以及
c) 收集在步骤 b) 中获得的 hiPSC 衍生皮脂前体细胞。
