objective: 的抑制作用,我们的目标activity of caffeic acid and its hydroxycinnamate analogues, rosmarinic acid and salvianolic acid A, in comparison to a known NA inhibitor, oseltamivir.
METHODS: In vitro MUNANA-based NA inhibitory assay was used to evaluate the inhibitory activity of the three interested羟基动力化合物朝向流感酶。随后,使用Allatom分子动力学(MD)模拟和结合自由能计算来阐明对蛋白质 - 连接络合物的结构见解。
sub_abstract_label“>结果: (IC50为0.81μm)和salvianolic Acid A(IC50>1μm)。从100-ns MD模拟中,奥马林酸/Na复合物的结合亲和力,热点残基和H键形成高于咖啡酸/Na模型的结合亲和力,HOND仿真。分子络合物主要由来自几个带电残基的静电景点和H键形成驱动(R118,E119,D151,R152,E227,E277和R371)。 Notably, the two hydroxyl groups on both phenyl and phenylacetic rings of rosmarinic acid play a crucial role in stabilizing NA through a strongly formed Hbond( s).
CONCLUSION: Our findings shed light on the potentiality of rosmarinic acid as a lead compound for further development of a potential流感抑制剂。
