staphylococci and Escherichia coli. While no biofilm structure destruction occurred, all compounds were able to diffuse into the matrix and reduce the number of colony-forming units by three orders of magnitude at 16 × MBC. The leading compound was significantly less toxic than miramistin and benzalkonium chloride and more toxic than the reference antifungal drugs. The obtained results make the described chemotype
通过
氟康唑与
吡哆醇基合成中间体的反应,合成了两种新型季
铵盐,即
氟康唑和
吡哆醇的双三唑鎓衍
生物。领先的化合物在体外表现出明显的抗真菌和抗菌活性,与参考抗真菌药(
氟康唑、
特比萘芬)和抗菌/
防腐剂(米拉米斯汀、苯扎
氯铵)相当或超过。与许多抗菌剂相比,主要化合物对
生物膜嵌入的葡萄球菌和大肠杆菌也有活性。虽然没有发生
生物膜结构破坏,但所有化合物都能够扩散到基质中,并在 16 × MBC 时将集落形成单位的数量减少三个数量级。领先化合物的毒性明显低于米拉米斯汀和苯扎
氯铵,而毒性高于参考抗真菌药物。获得的结果使所描述的
化学型成为开发新的广谱抗菌疗法的有希望的起点,对真菌和细菌病原体(包括其
生物膜嵌入形式)具有强大的影响。
