candidiasis that are related to its ability to produce biofilm on biological and artificial surfaces. Many studies reported the role of iron in fungal growth and virulence and the ability of metal chelating agents to interfere with C. albicans metabolism, virulence and biofilm formation. Here we report the activity of 3-hydroxy-1,2-dimethyl-4(1H)-pyridinone (deferiprone) derivatives against C. albicans planktonic
白色念珠菌在特定条件下会导致严重的侵袭性系统性念珠菌病,这与其在生物和人造表面产生生物膜的能力有关。许多研究报告了铁在真菌生长和毒力中的作用以及金属螯合剂干扰白色念珠菌代谢、毒力和生物膜形成的能力。 在这里,我们报告了 3-羟基-1,2-二甲基-4(1 H )-吡啶酮(去铁酮)衍生物对白色念珠菌浮游细胞和生物膜的活性。一些研究的化合物(2b和3b)能够螯合 Fe(III) 和 Cu(II),并对浮游细胞(MIC 50 分别为 32 μg/mL 和 16 μg/mL)和生物膜显示出有趣的活性在培养的 ATCC 10231白色念珠菌中形成(BMIC 50 分别为 32 μg/mL 和 16 μg/mL);通过向培养基中添加 Fe(III) 和 Cu(II),这种活性以浓度依赖的方式降低。此外,活性最强的化合物3b对Galleria mellonella幼虫。
