Adamantyl-Substituted Retinoid-Derived Molecules That Interact with the Orphan Nuclear Receptor Small Heterodimer Partner: Effects of Replacing the 1-Adamantyl or Hydroxyl Group on Inhibition of Cancer Cell Growth, Induction of Cancer Cell Apoptosis, and Inhibition of Src Homology 2 Domain-Containing Protein Tyrosine Phosphatase-2 Activity

namic acid (3-Cl-AHPC) induces the cell-cycle arrest and apoptosis of leukemia and cancer cells. Studies demonstrated that 3-Cl-AHPC bound to the atypical orphan nuclear receptor small heterodimer partner (SHP). Although missing a DNA-binding domain, SHP heterodimerizes with the ligand-binding domains of other nuclear receptors to repress their abilities to induce or inhibit gene expression. 3-Cl-AHPC
(E)-4-[3-(1-金刚烷基)-4'-羟基苯基]-3-氯肉桂酸 (3-Cl-AHPC) 诱导白血病和癌细胞的细胞周期停滞和凋亡。研究表明,3-Cl-AHPC 与非典型孤儿核受体小异二聚体伴侣 (SHP) 结合。虽然缺少 DNA 结合域,但 SHP 与其他核受体的配体结合域异二聚化以抑制它们诱导或抑制基因表达的能力。设计、合成了 3-Cl-AHPC 类似物,其中 1-金刚烷基和酚羟基药效元件被等排基团取代,并评估了它们抑制增殖和诱导人类癌细胞凋亡的作用。结构-抗癌活性关系研究表明两组对细胞凋亡活性的重要性。将 3-Cl-AHPC 及其类似物与 SHP 计算模型对接,该模型基于与 1-硬脂酰-2-棕榈酰甘油-3-磷酸乙醇胺复合的超气门的晶体结构,这表明为什么这些 3-Cl-AHPC 基团会影响 SHP 活性. 还评估了对含有 Src 同源 2 结构域的蛋白酪氨酸磷酸酶 2 (Shp-2) 的抑制活性。发现最活跃的
