  Structure and Thermotropic Phase Behavior of a Homologous Series ofN-Acylglycines: Neuroactive and Antinociceptive Constituents of Biomembranes

  摘要：

  N-Acylglycines (NAGs) with different acyl chains have been found in the mammalian brain and other tissues. They exhibit significant biological and pharmacological properties and appear to play important roles in communication and signaling pathways within and between cells. In view of this, a homologous series of NAGs have been synthesized and characterized in the present study. Differential scanning calorimetric (DSC) studies show that the transition enthalpies and entropies of dry as well as hydrated NAGs exhibit a linear dependence on the acyl chain length. Most of the NAGs show a minor transition below the chain-melting phase transition, suggesting the presence of polymorphism in the solid state. Structures of N-myristoylglycine (NMG) and N-palmitoylglycine (NPG) were solved in monoclinic system with C2/c and P2(1) space groups, respectively. Analysis of the crystal structures show that NAGs are organized in a bilayer fashion, with head-to-head (and tail-to-tail) arrangement of molecules. The acyl chains in both structures are essentially perpendicular to the bilayer plane, which is consistent with a lack of oddeven alternation in the thermodynamic properties. The bilayer is stabilized by strong hydrogen bonding interactions between -COOH groups of the molecules from opposite leaflets as well as NH center dot center dot center dot O hydrogen bonds between the amide groups of adjacent molecules in the same leaflet and dispersion interactions among the acyl chains. Powder X-ray diffraction data show that the d-spacings for the NAGs with different acyl chains (n = 820) exhibit a linear dependence on the chain length, suggesting that all the NAGs investigated here adopt a similar packing arrangement in the crystal lattice. These observations are relevant for understanding the role of N-acylglycines in biological membranes.

  A series of lipoamino acids were synthesized and their neuroprotective effect against brain ischemia induced by oxygen-glucose deprivation (OGD) on rat cerebral slices was evaluated. Among these compounds, N-stearoyl-L-tyrosine (4), N-stearoyl-L-serine (5) and N-stearoyl-L-threonine (6) exhibited good neuroprotective activity. We found that the neuroprotective activity of lipoamino acids depended on the acyl group, the presence of a free carboxylic function and a free hydroxyl group at the branched chain of the amino acids. The results also showed that 5 was the most active compound, protecting rat brain slices against OGD as well as hydrogen peroxide (H2O2) insult at the range of 1–10 M.

  一系列脂氨基酸被合成，并评估了它们对大鼠脑片由氧葡萄糖剥夺（OGD）诱导的脑缺血的神经保护作用。在这些化合物中，N-硬脂酰基-L-酪氨酸（4）、N-硬脂酰基-L-丝氨酸（5）和N-硬脂酰基-L-苏氨酸（6）表现出了良好的神经保护活性。我们发现，脂氨基酸的神经保护活性依赖于酰基团、氨基酸支链上自由羧基和自由羟基的存在。结果还显示，5是最活跃的化合物，在1-10 M的范围内保护大鼠脑片免受OGD和过氧化氢（H2O2）的损伤。

  N-acylamino hydrazides in various nonpolar and polar solvents (n-hexane, toluene, benzene, cyclohexane, and ethanol). Fatty N-acylamino hydrazide derived of the glycine and stearic acid (C18:0) did not form gels in any of the tested solvents. All other hydrazides did form gels in at least two of the organic solvents tested. The morphology of each gel was observed via scanning electron microscopy. The organogels

  这项工作首次报道了新的脂肪N-酰基氨基酰肼的合成，并证明了这些化合物作为低分子量有机胶凝剂和金纳米颗粒（AuNPs）制备模板的活性。最初，我们评估脂肪酸的凝胶化性能Ñ在各种非极性和极性溶剂-酰基酰肼（Ñ己烷，甲苯，苯，环己烷和乙醇）。由甘氨酸和硬脂酸（C18：0）衍生的脂肪N-酰氨基酰肼在任何测试的溶剂中均未形成凝胶。所有其他酰肼确实在至少两种测试的有机溶剂中形成了凝胶。通过观察每个凝胶的形态扫描电子显微镜。衍生自丙氨酸，缬氨酸和苯丙氨酸的有机凝胶具有半透明的特性，而丝氨酸有机凝胶则是不透明的。之后，实现了在有机胶凝剂的存在下使用微波辐射的AuNP的合成。有机胶凝剂还原HAuCl 4，显示530至543 nm之间的等离激元能带峰。另外，该方法不需要还原剂，还原剂通常是污染和毒性的潜在来源。因此，这项工作证实了新型脂肪N-酰基氨基酰肼中的酰肼基在凝胶形成中以及作为制备AuNPs的有机胶凝剂的重要性。
