Design,synthesis and antifungal activity of carbazole derivatives

The incidence of invasive fungal infections is increasing rapidly. Clinically available antifungal agents suffer from limited efficacy and severe resistance. There is an urgent need to discover antifungal lead compounds with novel chemical scaffold. On the basis of our previously identified tetrahydrocarbazole antifungal leads, the structure-activity relationship was further explored by modifying the scaffold and the side chains. Several targeted compounds showed potent activity against Candida species. Particularly, compound 13i showed better antifungal activity than the lead compound, which can be used as a good starting point for further optimization.     

基于标记法的福白菊精油抗真菌机理研究

以福白菊为原料, 通过有机溶剂萃取和水蒸气蒸馏相结合制备福白菊精油. 分别采用健那绿、 细胞膜荧光探针DiI、 碘化丙啶、 罗丹明123以及溴化乙锭等染料标记酵母细胞、 酵母细胞膜、 酵母线粒体和质粒DNA, 研究福白菊精油对酵母细胞、 酵母细胞膜、 线粒体以及质粒DNA的破坏作用, 探讨福白菊精油的抗真菌机理. 研究结果表明, 福白菊精油不仅能破坏真菌的细胞膜, 使其细胞内含物外泄, 还能够穿过细胞膜, 破坏其线粒体膜和DNA, 最终导致真菌细胞死亡.
