Antifungal activity of cisatracurium against fluconazole-resistant Candida isolates and its antibiofilm effects - Supplementary material

<b>Aim: </b>To evaluate the antifungal activity of cisatracurium against <i>Candida </i>spp. resistant to fluconazole strains in planktonic and biofilm forms, in addition to determining its mechanism of action. <b>Materials &amp; methods: </b>Antifungal activity and pharmacological interactions were determined using broth microdilution methods and the mechanism of action was evaluated by flow cytometry and molecular docking. <b>Results: </b>Cisatracurium presented antifungal activity against <i>Candida </i>spp. planktonic cells due to alterations of mitochondrial transmembrane potential leading to cellular apoptosis in addition to interacting with important targets related to cellular respiration, membrane and cell wall evidenced by molecular docking. Furthermore, the drug both prevented biofilm formation and impaired mature biofilms. <b>Conclusion: </b>Cisatracurium exhibits potential antifungal activity against <i>Candida </i>spp.
