A structure–activity relationship study to elucidate the structural basis for hedgehog (Hh) signaling inhibition by vitamin D3 (VD3) was performed. Functional and non-functional regions of VD3 and VD2 were obtained through straightforward synthetic means and their biological activity was determined in a variety of cell-based assays. Several of these compounds inhibited Hh signaling at levels comparable
进行了结构-活性关系研究,阐明了维生素D3(VD3)抑制刺猬(Hh)信号的结构基础。VD3和VD2的功能区和非功能区通过简单的合成方法获得,其生物学活性在各种基于细胞的测定中确定。这些化合物中的几种以与亲本VD3相当的水平抑制Hh信号传导,而对规范的维生素D信号传导没有影响。最值得注意的是化合物5和9证明了对Hh途径的有效抑制,对维生素D受体(VDR)没有结合亲和力,并且在细胞培养中没有激活VDR。此外,几种化合物通过不同于Hh或VDR途径的机制对两种人类癌细胞系表现出抗增殖活性,这表明这类化合物具有新的细胞作用机制。
