  Synthesis of Migration-Resistant Hydroxyethoxy Analogues of Lysophosphatidic Acid

  摘要：

  The susceptibility of lysophosphatidic acid (LPA) to intramolecular acyl migration impedes the determination of specific receptor activation by the sn-1 and sn-2 LPA regioisomers. An efficient enantioselective synthesis of hydroxyethoxy (HE)-substituted analogues of sn-1-acyl and 2-acyl LPA derivatives that possess palmitoyl and oleoyl chains is described. While the palmitoyl derivatives fall to activate calcium release in cells transfected with LPA(2) or LPA(3) G-protein-coupled receptors, the LPA(3) receptor is activated by both 1-HE and 2-HE oleoyl LPA analogues with a potency 10-fold lower than that of the parent oleoyl LPA.

• New fluorescent probes reveal that flippase-mediated flip-flop of phosphatidylinositol across the endoplasmic reticulum membrane does not depend on the stereochemistry of the lipid

  Glycerophospholipid flip-flop across biogenic membranes such as the endoplasmic reticulum (ER) is a fundamental feature of membrane biogenesis. Flip-flop requires the activity of specific membrane proteins called flippases. These proteins have yet to be identified in biogenic membranes and the molecular basis of their action is unknown. It is generally believed that flippase-facilitated glycerophospholipid flip-flop across the ER is governed by the stereochemistry of the glycerolipid, but this important issue has not been resolved. Here we investigate whether the ER flippase stereochemically recognizes the glycerophospholipids that it transports. To address this question we selected phosphatidylinositol (PI), a biologically important molecule with chiral centres in both its myo-inositol headgroup and its glycerol–lipid tail. The flip-flop of PI across the ER has not been previously reported. We synthesized fluorescence-labeled forms of all four diastereoisomers of PI and evaluated their flipping in rat liver ER vesicles, as well as in flippase-containing proteoliposomes reconstituted from a detergent extract of ER. Our results show that the flippase is able to translocate all four PI isomers and that both glycerol isomers of PI flip-flop across the ER membrane at rates similar to that measured for fluorescence-labeled phosphatidylcholine. Our data have important implications for recent hypotheses concerning the evolution of distinct homochiral glycerophospholipid membranes during the speciation of archaea and bacteria/eukarya from a common cellular ancestor.

  甘油磷脂在生物膜（如内质网）上的翻转是膜生物发生的一个基本特征。翻转需要特定膜蛋白（即翻转酶）的活性，但这些蛋白质在生物膜中的身份尚未确定，其作用的分子基础也还不清楚。一般认为，内质网上的翻转酶介导的甘油磷脂翻转受甘油磷脂的手性化学支配，但这一重要问题尚未解决。在此，我们研究内质网翻转酶是否手性识别其转运的甘油磷脂。为解答这一问题，我们选择了磷脂酰肌醇，这种生物学上重要的分子在其肌醇头基和甘油脂尾上都具有手性中心。之前并未有过关于磷脂酰肌醇在内质网翻转的报道。我们合成了所有四种磷脂酰肌醇的非对映异构体并进行荧光标记，评估它们在大鼠肝脏内质网囊泡及从内质网洗涤剂提取物重建的含翻转酶的蛋白脂质体中的翻转情况。结果显示，翻转酶能够转运所有的磷脂酰肌醇异构体，两种磷脂酰肌醇的甘油异构体在内质网膜上的翻转速率与荧光标记的磷脂酰胆碱相当。这些数据对近期有关古菌和细菌/真核生物从共同的细胞祖先演化出不同手性的甘油磷脂膜的假设有着重要意义。

  receptors have yet to be found. We have designed and synthesized a set of phosphatidylserine lipid mimics with a PS lipid headgroup for recognition, a benzophenone moiety for photoaffinity cross-linking, and an alkyne for post-labeling readout. These probes may be useful tools to identify new PS receptors (PSRs). The PS lipid probes thus have potential impact in the areas of discovery biology, anti-inflammatory

  磷脂酰丝氨酸 (PS) 脂质在细胞生物学中发挥多种作用，其中之一是标记凋亡细胞以供巨噬细胞清除。PS 识别触发巨噬细胞识别和清除，这与炎症反应的主动抑制同时发生。不同组织中的少量蛋白质已被鉴定为 PS 受体，我们假设尚未发现更多的 PS 受体。我们设计并合成了一组磷脂酰丝氨酸脂质模拟物，带有用于识别的 PS 脂质头部基团、用于光亲和交联的二苯甲酮部分以及用于标记后读出的炔烃。这些探针可能是识别新 PS 受体 (PSR) 的有用工具。因此，PS 脂质探针在发现生物学、抗炎疗法和细胞递送领域具有潜在影响。

  chemical synthesis of glycosyl inositol phospholipids from Entamoeba histolytica is reported. The key feature of this synthesis is a regioselective phosphorylation reaction that occurs through desymmetrization of a myo‐inositol derivative with phosphoroselenoyl chloride. A new protecting‐group strategy was developed that utilizes allyl and alloc groups to synthesize complex glycolipids bearing unsaturated
