合成的磷脂酰肌醇磷酸(PtdInsPn)衍生物在拓宽我们对PtdInsPn代谢的理解方面发挥着关键作用。然而,此类工具的开发依赖于有效的对映选择性和区域选择性合成策略。在这里,我们报告了一个发散的合成路线适用于合成氘代PtdIns 4P和PtdIns 5 P衍生物的发展。开发的合成策略涉及使用LipozymeTL-IM ®的关键酶促去对称化步骤。此外,我们优化了氘代肌醇的大规模合成,允许制备一系列饱和和不饱和的氘代PtdIns 4P和PtdIns 5 P衍生物。MCF 7细胞中的实验证明,这些氘代探针能够定量细胞环境中相应的内源性磷脂。总的来说,这些氘化探针将成为强大的工具,有助于我们更好地了解PtdInsPn在生理和疾病中所发挥的作用。我们报告的合成氘标记的衍生物的磷脂酰肌醇4-磷酸和磷脂酰肌醇5-磷酸,并证明其在定量细胞中的内源性磷脂的水平。
Synthetic phosphatidylinositol phosphate (PtdInsPn) derivatives play a pivotal role in broadening our understanding of PtdInsPn metabolism. However, the development of such tools is reliant on efficient enantioselective and regioselective synthetic strategies. Here we report the development of a divergent synthetic route applicable to the synthesis of deuterated PtdIns4P and PtdIns5P derivatives. The synthetic strategy developed involves a key enzymatic desymmetrisation step using Lipozyme TL-IM®. In addition, we optimised the large-scale synthesis of deuterated myo-inositol, allowing for the preparation of a series of saturated and unsaturated deuterated PtdIns4P and PtdIns5P derivatives. Experiments in MCF7 cells demonstrated that these deuterated probes enable quantification of the corresponding endogenous phospholipids in a cellular setting. Overall, these deuterated probes will be powerful tools to help improve our understanding of the role played by PtdInsPn in physiology and disease. We report the synthesis of deuterium-labelled derivatives of phosphatidylinositol 4-phosphate and phosphatidylinositol 5-phosphate, and demonstrate their use in quantifying levels of endogenous phospholipids in cells.
