  Recently, the ionic liquid (IL) choline dihydrogen phosphate was demonstrated to improve the thermostability and shelf life of several model proteins, thus exhibiting potential as a stabilizing excipient or solvent for protein therapeutics. Before novel ILs can be used for biomedical applications, comprehensive data is required to establish biocompatibility, including cytotoxicity effects and solution behavior. In this study five phosphate-based anion moieties were analyzed: H2PO4− (DHP), dibutyl phosphate (DBP), bis(2-ethylhexyl) phosphate (BEH), bis(2,4,4-trimethylpentyl) phosphinate (TMP), and O,O′-diethyl dithiophosphate (DEP), all paired with the cation choline (C). Toxicity levels for these ILs, and a common sugar and salts, were established using a J774 murine macrophage cell line. The sugar trehalose, and the simple salts sodium chloride and choline chloride yielded EC50 values of >100, 63 and 34 mM, respectively. The EC50 values (mM) of CDHP (20), CDBP (9.1), and CDEP (8.2) were lower than, but within the range of simple salts NaCl (62.8) and choline Cl (33.7). The EC50 values of CTMP and CBEH were considerably lower, 0.25 and 0.30 mM, respectively. CDHP and CBEH displayed a hormetic response. Osmolality measurements indicated that CDHP, CDBP, and CDEP exhibit nearly complete dissociation in aqueous solution, with osmotic coefficients of 1.0, 0.9, and 0.8, whereas CTMP and CBEH have coefficients of 0.5 and 0.3, and are more molecular in character. A high correlation between the EC50 value and the anion mass fraction indicated that anion size and the presence of moderately long and/or branched alkyl chains may affect viability.

  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.

The influence of the ionic liquid on the amplification process during the PCR was further investigated, showing an inhibitory effect with increasing chain length of the ionic liquid and with higher ionic liquid concentrations.
