mortality by fungal infections and the emergence of severe antifungal resistance, there is an urgent need for new antifungal agents. Here, we screened for antifungal activity in our in-house library through the minimum inhibitory concentration test and derived two hit compounds with moderate antifungal activities. The hit compounds’ antifungal activities and drug-like properties were optimized by substituting
由于真菌感染的发病率和死亡率增加以及严重的抗真菌耐药性的出现,迫切需要新的抗真菌药物。在这里,我们通过最低抑菌浓度测试在我们的内部库中筛选抗真菌活性,并衍生出两种具有中等抗真菌活性的命中化合物。通过取代各种芳环、烷基链和甲基,优化了命中化合物的抗真菌活性和类药特性。在优化的化合物中, 22h是最有前途的候选化合物,具有良好的类药特性,对多种真菌病原体表现出强效、快速的杀菌抗真菌作用,并与一些已知的抗真菌药物具有协同抗真菌活性。此外, 22h被进一步证实可以通过激活多个细胞壁完整性途径来扰乱真菌细胞壁的完整性。此外, 22h在皮下感染小鼠模型和离体人指甲感染模型中均发挥显着的抗真菌功效。
