The current trend in microbiological research aimed at limiting the development of biofilms of multidrug-resistant microorganisms is increasingly towards the search for possible synergistic effects between various compounds. This work presents a combination of a naturally occurring compound, β-aescin, newly synthesized alkylamidobetaines (AABs) with a general structure-CTMDAB, and antifungal drugs. The research we conducted consists of several stages. The first stage concerns determining biological activity (antifungal) against selected multidrug-resistant strains of () with the highest ability to form biofilms. The second stage of this study determined the activity of β-aescin combinations with antifungal compounds and alkylamidobetaines. In the next stage of this study, the ability to eradicate a biofilm on the polystyrene surface of the combination of β-aescin with alkylamidobetaines was examined. It has been shown that the combination of β-aescin and alkylamidobetaine can firmly remove biofilms and reduce their viability. The last stage of this research was to determine the safety regarding the cytotoxicity of both β-aescin and alkylamidobetaines. Previous studies on the fibroblast cell line have shown that C9 alkylamidobetaine can be safely used as a component of anti-biofilm compounds. This research increases the level of knowledge about the practical possibilities of using anti-biofilm compounds in combined therapies against .
当前,微生物学研究领域的一个主要趋势是寻找各种化合物之间可能存在的协同作用,以限制多药耐药微生物生物膜的发展。本研究将天然存在的化合物β-七叶皂甙与新合成的具有一般结构 CTMDAB 的烷基酰胺甜菜碱(AAB)以及抗真菌药物结合在一起。我们的研究工作包括几个阶段。第一阶段涉及确定对所选多药耐药菌株()的生物活性(抗真菌),这些菌株具有最强的形成生物膜的能力。本研究的第二阶段确定了β-七叶皂甙与抗真菌化合物和烷基酰胺甜菜碱组合的活性。在本研究的下一阶段,研究了β-七叶皂甙与烷基酰胺甜菜碱组合消除聚苯乙烯表面生物膜的能力。结果表明,β-七叶皂甙和烷基酰胺甜菜碱的组合可以牢固地去除生物膜并降低其活力。本研究的最后一个阶段是确定β-七叶皂甙和烷基酰胺甜菜碱的细胞毒性安全性。先前对成纤维细胞系的研究表明,C9 烷基酰胺甜菜碱可以安全地用作抗生物膜化合物的组成部分。本研究提高了关于在联合疗法中使用抗生物膜化合物来对抗的实际可能性的认识水平。
