  摘要：

  最近，离子液体（IL）磷酸胆碱（choline dihydrogen phosphate）被证明可改善几种模型蛋白质的热稳定性和保质期，因此具有作为蛋白质治疗的稳定赋形剂或溶剂的潜力。在新型 IL 用于生物医学应用之前，需要全面的数据来确定其生物相容性，包括细胞毒性效应和溶液行为。本研究分析了五种基于磷酸盐的阴离子分子：H2PO4-（DHP）、磷酸二丁酯（DBP）、双（2-乙基己基）磷酸酯（BEH）、双（2,4,4-三甲基戊基）膦酸酯（TMP）和 O,O′-二乙基二硫代磷酸酯（DEP），它们都与阳离子胆碱（C）配对。利用 J774 鼠巨噬细胞系确定了这些 IL 以及一种常见糖类和盐类的毒性水平。糖类三卤糖和单盐氯化钠及氯化胆碱的 EC50 值分别大于 100、63 和 34 mM。CDHP（20）、CDBP（9.1）和 CDEP（8.2）的 EC50 值（毫摩尔）低于单盐氯化钠（62.8）和氯化胆碱（33.7），但在其范围之内。CTMP 和 CBEH 的 EC50 值要低得多，分别为 0.25 和 0.30 毫摩尔。CDHP 和 CBEH 显示出激素反应。渗透压测量结果表明，CDHP、CDBP 和 CDEP 在水溶液中几乎完全解离，渗透系数分别为 1.0、0.9 和 0.8，而 CTMP 和 CBEH 的渗透系数分别为 0.5 和 0.3，更具有分子特征。EC50 值与阴离子质量分数之间的高度相关性表明，阴离子的大小以及是否存在中等长度和/或支化的烷基链可能会影响存活率。

  A method of screening an organic salt for potential toxicity if used as a stabilizing agent for live cells or viruses, the method comprising: (a) providing a composition of unilamellar vesicles; then (b) contacting an organic salt to the unilamellar vesicles; and then (c) detecting a change in at least one thermal parameter of the unilamellar vesicles caused by the organic salt at said known concentration. A change in the at least one thermal parameter indicates the organic salt is potentially toxic for use as a stabilizing agent for live cells or viruses. Compositions of organic salts identified by such methods, along with methods of using the same in stabilizing live cells or viruses, are also described.

  Anti-wear and/or friction reducing formulations that include a mixture of at least one first ionic liquid and at least one ashless antiwear compound. The ashless antiwear compound can be a second ionic liquid or an ashless thiophosphate compound. The formulation desirably provides synergistic anti-wear and/or friction reducing properties. The first IL can be a monocationie ionic liquid or a dicationic ionic liquid. The second IL is a dicationic ionic liquid. The ashless thiophosphate is desirably a thiophosphate, such as a fluorothiophosphate (FTP), an alkylphosphorofluoridothiolate, or an alkylthioperoxydithiophosphate. Antiwear and/or friction reduction formulations comprising the above mixtures diluted up to 25% by weight in a base oil.
