of novel antifungal agents and severe drug resistance has led to high incidence and associated mortality of invasive fungal infections. To tackle the challenges, novel antifungal agents with anti‐resistant potency are highly desirable. Thus, derivatives of curcumin were synthesized to restore the effectiveness of fluconazole (FLC) against FLC‐resistant Candida spp. and structure‐activity relationships
缺乏新型抗真菌剂和严重的耐药性导致侵袭性真菌感染的高发病率和相关死亡率。为了应对这些挑战,非常需要具有抗药性的新型抗真菌剂。因此,合成姜黄素衍生物以恢复氟康唑 (FLC) 对 FLC 抗性念珠菌的有效性。然后讨论了构效关系。一些新型衍生物显示出作为新型抗真菌先导化合物的前景。其中,化合物4对FLC抗性念珠菌属表现出良好的单独或协同抗真菌活性。此外,化合物4被证明是一种有效的白色念珠菌抑制剂无论是单独使用还是与 FLC 联合使用,生物膜形成和酵母菌到菌丝的形态转变,这通过对白色念珠菌细胞表面疏水性的抑制作用得到进一步证实。化合物4还抑制细胞内ATP生成白色念珠菌和破坏的细胞膜的通透性白色念珠菌与FLC组合使用时。结果突出了姜黄素衍生物克服氟康唑相关和生物膜相关耐药性的潜力。
