The growing use of ionic liquids (ILs) necessitates an understanding of their environmental impact and toxicity levels. In this study, a series of amino acid-based ionic liquids containing the triethanolammonium (TEA) cation were evaluated for their biological activity against L., the mouse fibroblast cell line L929, a selection of gram-positive and gram-negative bacteria, and the yeast . The influence of amino acid anion structure on toxicity was also examined. Among the tested ionic liquids, [TEA][Asp] exhibited low toxicity toward , representing terrestrial plants, while [TEA][Phe] showed the lowest cytotoxicity. Regarding microbial activity, [TEA][Lys] demonstrated greater bactericidal effectiveness against than , while both [TEA][Lys] and [TEA][Arg] exhibited the strongest inhibitory effect against Our findings underscore the crucial role of IL salt composition in determining biological activity, highlighting the significance of interactions between IL components in shaping their potential effects.
离子液体(ILs)的使用日益广泛,因此有必要了解它们对环境的影响和毒性水平。在本研究中,对一系列含有三乙醇铵(TEA)阳离子的氨基酸基离子液体针对生菜、小鼠成纤维细胞系L929、多种革兰氏阳性和革兰氏阴性细菌以及酵母的生物活性进行了评估。还研究了氨基酸阴离子结构对毒性的影响。在所测试的离子液体中,[TEA][Asp]对代表陆生植物的生菜表现出低毒性,而[TEA][Phe]表现出最低的细胞毒性。关于微生物活性,[TEA][Lys]对金黄色葡萄球菌的杀菌效果比对大肠杆菌更强,而[TEA][Lys]和[TEA][Arg]对白色念珠菌均表现出最强的抑制作用。我们的研究结果强调了离子液体盐组成在决定生物活性方面的关键作用,突出了离子液体成分之间的相互作用在塑造其潜在影响方面的重要性。
