  Metabolically Stabilized Derivatives of Phosphatidylinositol 4-Phosphate: Synthesis and Applications

  摘要：

  Phosphatidylinositol 4-phosphate (PtdIns(4)P) lipid is an essential component of eukaryotic membranes and a marker of the Golgi complex. Here, we developed metabolically stabilized (ms) analogs of PtdIns(4)P and the inositol 1,4-bisphosphate (IP(2)) head group derivative and demonstrated that these compounds can substitute the natural lipid fully retaining its physiological activities. The methylenephosphonate (MP) and phosphorothioate (PT) analogs of PtdIns(4)P and the aminohexyl (AH)-1P(2) probe are recognized by the PtdIns(4)P-specific PH domain of four phosphate adaptor protein 1 (FAPP1). Binding of FAPP1 to the PtdIns(4)P derivatives stimulates insertion of the PH domain into the lipid layers and induces tubulation of membranes. Both ms analogs and IP(2) probes could be invaluable for identifying protein effectors and characterizing PtdIns(4)P-dependent signaling cascades within the trans-Golgi network (TGN).

  derivatized analogs of use for different studies. In addition to the application of this strategy to generate PI-(4,5)-P2 headgroup probes, we also report the synthesis of PIPn–amine conjugates corresponding to all seven naturally existing isomers. This approach will be invaluable for generating the range of probe structures that is required to elucidate the intricacies of PIPn signaling. (© Wiley-VCH Verlag

  磷脂酰肌醇聚磷酸脂 (PIPns) 在重要的生物学途径中发挥着关键作用，这些分子的信号活动缺陷与许多疾病状态有关。因此，有必要了解这些脂质在生物途径中的复杂作用，这通常涉及它们作为位点特异性配体的作用，将受体募集到细胞膜表面。然而，PIPn 家族成员的复杂结构，其中存在七种生物活性异构体，使研究复杂化。PIPn 结构的衍生类似物可用作阐明信号和结合活性的化学工具。在此处，我们提出了一种有效的方法来探测 PIPn 头基的氨基缀合物可以在合成的最后一步方便地功能化的生成，以获得用于不同研究的许多衍生类似物。除了应用此策略生成 PI-(4,5)-P2 头基探针外，我们还报告了与所有七种天然存在的异构体相对应的 PIPn-胺缀合物的合成。这种方法对于生成阐明 PIPn 信号的复杂性所需的探针结构范围非常宝贵。(© Wiley-VCH Verlag GmbH & Co.
