promising therapeutic strategy. In this study, a series of deguelin (Deg) derivative were prepared and identified with in vitro antifungal activity against drug-resistant C. albicans combined with fluconazole (FLC). The combination of Deg derivative 17c and FLC exhibited the best activity, with a fractional inhibitory combination index (FICI) of 0.02. The sensitization effect of 17c + FLC was further
白色念珠菌作为最常见的条件致病菌,给临床治疗带来了很大的困难。与此同时,随着唑类药物在临床实践中的广泛应用,耐药性也随之出现。在这种情况下,采用联合治疗就成为一种有前景的治疗策略。本研究制备了一系列德桂林(Deg)衍生物,并鉴定其与氟康唑(FLC)联用对耐药白色念珠菌具有体外抗真菌活性。Deg衍生物17c和FLC的组合表现出最好的活性,其抑制组合指数(FICI)为0.02。 通过时间杀菌曲线分析进一步验证了17c +FLC的致敏效果。此外,17c + FLC 还对耐药白色念珠菌 的菌丝转化和生物膜形成具有抑制作用,并显着降低与 RAS1/cAMP/PKA 细胞转导途径相关的关键基因的表达。
