non-nitrogenous aromatic ether Neuraminidase (NA) inhibitors. Their structures are simple and the synthesis routes are not complex. The structure-activity relationship (SAR) analysis revealed that the aryl aldehyde and unsubstituted hydroxyl were important to NA inhibitory activities. Molecular docking studies were carried out to explain the SAR of the compounds, and provided valuable information for further
基于来自红树林真菌的天然异戊二烯苯基醚,合成了 32 种类似物并评估了其对流感 H1N1 神经氨酸酶的抑制活性。化合物 15 (3-(烯丙氧基)-4-羟基苯甲醛) 表现出最有效的抑制活性,A/GuangdongSB/01/2009 (H1N1) 的 IC(50) 值为 26.96 μM,A/Guangdong/03/ 为 27.73 μM 2009 (H1N1) 和 A/Guangdong/05/2009 (H1N1) 分别为 25.13 μM,比苯甲酸衍生物强(~mM 水平)。这是一种新型的非含氮芳香醚神经氨酸酶(NA)抑制剂。它们的结构简单,合成路线并不复杂。构效关系(SAR)分析表明芳醛和未取代的羟基对NA抑制活性很重要。
