  摘要：

  最近，真菌鞘脂糖基神经酰胺（GlcCer）的合成已成为下一代抗真菌药的药物开发的高度有希望的新目标，我们基于HTP筛选发现了两种芳香族酰基hydr作为GlcCer合成的有效抑制剂。在目前的工作中，我们设计了新的芳香族酰基hydr的文库，评估了它们对新孢子虫的抗真菌活性（MIC80和时间杀灭谱），并进行了广泛的SAR研究，从而鉴定了五种有前途的先导化合物，极高的选择性指数，具有出色的杀真菌活性。此外，两种化合物对其他六种临床相关真菌菌株均具有广谱抗真菌活性。研究了这五种先导化合物与五种临床药物对七种真菌菌株的协同作用/协同作用，并获得了令人鼓舞的结果。例如，所有五个先导化合物与伏立康唑的组合对所有七个真菌菌株均表现出协同作用或加和作用。
