We have conducted systematic structural modification, deconstruction, and reconstruction of the berberine core with the aim of lowering its cytotoxicity, investigating its pharmacophore, and ultimately, seeking novel synergistic agents to restore the effectiveness of fluconazole against fluconazole‐resistant Candida albicans. A structure–activity relationship study of 95 analogues led us to identify
我们已经对黄连素核心进行了系统的结构修饰,解构和重建,以降低其小toxic碱的细胞毒性,研究其药效团,并最终寻求新型协同剂以恢复氟康唑对耐氟康唑的白色念珠菌的有效性。通过对95个类似物的构效关系研究,我们确定了N-(2-(苯并[ d ] [1,3]二恶酚-5-基)乙基)-2-(取代的苯基)乙酰胺的新型骨架7 a -升,这表现出在体外协同抗真菌活性的显着水平。化合物7 d(N-(2-(苯并[ d] [1,3]二恶唑-5-基)乙基)-2-(2-氟苯基)乙酰胺)可显着降低氟康唑相对于耐氟康唑的C的MIC 80值,从128.0μgmL -1降至0.5μgmL -1 。白色念珠菌对人脐静脉内皮细胞的毒性比黄连素低得多。
