have shown promising antifungal properties against Candida yeast and have emerged as valuable candidates for developing new candidiasis therapies. In this work, we isolated isodrimeninol (C1) from barks of Drimys winteri and used it as starting material for the hemi-synthesis of four sesquiterpenoids by oxidation with pyridinium chlorochromate (PCC). The structure of the products (C2, C3, C4, and C5)
念珠菌导致机会性酵母菌感染,称为念珠菌病,全世界每年造成50,000多例死亡。抗由非白色念珠菌念珠菌有效的治疗方法念珠菌物种如光滑念珠菌,近平滑念珠菌,C.黄色葡萄球菌,和C. 克柔是有限的,由于常规的抗真菌药物抗性严重。天然drimane倍半萜类化合物已显示出针对念珠菌的有希望的抗真菌特性,并已成为开发新念珠菌疗法的有价值的候选药物。在这项工作中,我们从Drimys winteri的树皮中分离了异烯菊醇(C1)并用作通过氯铬酸吡啶鎓(PCC)氧化半合成四倍半萜的原料。通过1D和2D NMR光谱法阐明了产物(C2,C3,C4和C5)的结构,导致C4为新型化合物。在所有酵母菌株中,针对白色念珠菌,光滑念珠菌和克鲁氏梭菌的抗真菌活性分析表明,与C1相比,C4的活性更高(IC 50为75μg/ mL)(IC 50为125μg/ mL)。C1和C4的抗真菌活性使用分子对接,分子动力学模拟和MM /
