  Synthesis and biological evaluation of phosphatidylinositol phosphate affinity probes

  摘要：

  报道了从五个关键的核心中间体A-E合成完整的磷脂酰肌醇磷酸类似物（PIPs）家族的方法。这些核心化合物通过选择性DIBAL-H和三甲基铝介导的裂解以及使用樟脑乙缩醛的解析保护过程，从肌醇原甲酸1中获得。将核心A-E与从所需保护的脂质侧链衍生的磷酰胺34和38偶联，得到了完全保护的PIPs。通过使用钯黑或碳上的钯氢氧化物在碳酸氢钠存在下的氢解，去除了剩余的保护基团，得到了完整的二棕榈酰和氨基PIP类似物42、45、50、51、58、59、67、68、76、77、82、83、92、93、99和100。利用包含这些化合物的亲和探针进行的研究，鉴定了参与PI3K细胞内信号网络的新蛋白，并允许对磷脂酰肌醇相互作用蛋白进行全面的蛋白质组学分析。

  在人滑膜磷脂酶A2活性位点的短链磷脂类似物的底物特异性。

  摘要：

  通过制备一系列短链磷脂类似物并在远低于临界胶束浓度的条件下测量其酶解作用，研究了重组人滑液磷脂酶A2（hs-PLA2）活性位点的底物特异性。研究中使用的底物包括1,2-二己基甘油磷脂，1,2-双（烷酰基硫基）甘油磷脂和1-O-烷基-2-（烷酰基硫基）磷脂。仅观察到少量的1,2-二己酰基甘油磷脂脂质，且水解速率非常低，接近测定的检测极限。相反，选定的2-（烷酰硫基）-甘油磷脂在远低于其临界胶束浓度（cmc）的浓度下，被hs-PLA2水解得更高的速率。因此，1 2-双（己基硫基）甘油磷脂酰乙醇的ak（cat）/ K（M）= 1800 L mol-1 s-1。在计算的log P（cLogP）3-9范围内，具有直链sn-1和sn-2取代基的化合物的cLogP和log（k（cat）/ K（M）线性相关。 Sn-1醚和硫酯的水解速度相当，磷酸酯基团需要负电荷才能发挥酶的活性，sn-2取代基的不饱和度，芳香性和支链会大大减少周转率。

• Cardiolipin molecules and methods of synthesis

  The invention provides new synthetic routes for cardiolipin with different fatty acids and/or alkyl chains with varying chain length and also with or without unsaturation, particularly a short-chain cardiolipin. The methods comprise reacting a 1,2-O-sn-diacyl/1,2-O-sn-dialkyl glycerol or a 2-O-protected glycerol, with a phosphoramidite reagent or a phosphate triester to produce a protected cardiolipin, which is deprotected to prepare the short chain cardiolipin. The reaction schemes can be used to generate new variants of cardiolipin. The cardiolipin prepared by the present methods can be incorporated into liposomes, which can also include active agents such as hydrophobic or hydrophilic drugs. Such liposomes can be used to treat diseases or in diagnostic and/or analytical assays. Liposomes can also include ligands for targeting a particular cell type or specific tissue.

• General Method for the Synthesis of Phospholipid Derivatives of 1,2-O-Diacyl-sn-Glycerols

  An efficient phosphite coupling protocol is described for the syntheses of the major classes of phospholipids that are derived from 1,2-O-diacyl-sn-glycerols and analogues thereof. The symmetrical diacyl glycerols 10c,d were prepared by straightforward acylation of 3-O-benzyl-sn-glycerol (7) with the appropriate carboxylic acid in the presence of dicyclohexylcarbodiimide (DCC) and 4-(dimethylamino)pyridine (DMAP). A simple method for preparing saturated and unstaturated mixed 1,2-O-diacyl-sn-glycerols was then devised that involved stepwise acylation of 7 with different alkyl carboxylic acids and debenzylation this procedure is exemplified by the preparation of 10a,b. The 1,2-O-diacyl-sn-glycerols 10a-d were then coupled with suitably protected lipid head groups employing reactive alkyl or aryl dichlorophosphites to give intermediate phosphite triesters in high overall yields. Oxidation or sulfurization of these phosphites proceeded smoothly to give the corresponding phosphate or phosphorothioate triesters, deprotection of which then provided the phosphatidylcholines 16 and 17, the phosphatidylethanolamine 20, the phosphatidylserine 28, and the phosphatidylinositols 37 and 38. Preparation of 37 and 38 required the invention of an improved method for resolving the isopropylidene-protected D-myo-inositol derivative 33. This phosphite coupling procedure was modified to assemble phospholipids bearing-polyunsaturated acyl side chains at the sn-2-position as exemplified by the preparation of the phosphatidylethanolamine 26. The one-pot phosphite coupling procedure is also applicable to the syntheses of a variety of other biologically interesting phospholipid analogues. For example, the phosphatidylinositol analogues 49-51, in which the hydroxyl group at C(2) of the inositol ring has been modified, were prepared in excellent overall yields by conjoining the 1,2-O-diacyl-sn-glycerol 10c with the protected inositol derivatives 44, 45, and 48. Phospholipid analogues that contain other replacements of the phosphate group including phosphoramidates and thiophosphates maybe prepared as evidenced by the syntheses of 56 and 61 in which the sn-3 oxygen atom of the 1,2-O-diacyl-sn-glycerol moiety is replaced with an N-benzyl group or a sulfur atom, respectively.

  The synthesis of the complete family of phosphatidylinositol phosphate analogues (PIPs) from five key core intermediates A–E is described. These core compounds were obtained from myo-inositol orthoformate 1via regioselective DIBAL-H and trimethylaluminium-mediated cleavages and a resolution–protection process using camphor acetals 10. Coupling of cores A–E with phosphoramidites 34 and 38, derived from the requisite protected lipid side chains, afforded the fully-protected PIPs. Removal of the remaining protecting groups was achieved via hydrogenolysis using palladium black or palladium hydroxide on carbon in the presence of sodium bicarbonate to afford the complete family of dipalmitoyl- and amino-PIP analogues 42, 45, 50, 51, 58, 59, 67, 68, 76, 77, 82, 83, 92, 93, 99 and 100. Investigations using affinity probes incorporating these compounds have identified novel proteins involved in the PI3K intracellular signalling network and have allowed a comprehensive proteomic analysis of phosphoinositide interacting proteins.

  The substrate specificity at the active site of recombinant human synovial fluid phospholipase A2 (hs-PLA2) was investigated by the preparation of a series of short-chain phospholipid analogs and measurement of their enzymatic hydrolysis at concentrations well below the critical micelle concentration. Substrates used in the study included 1,2-dihexanoylglycerophospholipids, 1,2-bis(alkanoylthio)glycerophospholipids
