In order to find novel antiviral agents, a series of allosteric MEK1 inhibitors were designed and synthesized. Based on docking results, multiple optimizations were made on the coumarin scaffold. Some of the derivatives showed excellent MEK1 binding affinity in the appropriate enzymatic assays and displayed obvious inhibitory effects on the ERK pathway in a cellular assay. These compounds also significantly inhibited virus (EV71) replication in HEK293 and RD cells. Several compounds showed potential as agents for the treatment of viral infective diseases, with the most potent compound 18 showing an IC50 value of 54.57 nM in the MEK1 binding assay.
为了寻找新型抗病毒药物,设计并合成了一系列别构MEK1抑制剂。基于对接结果,对香豆素支架进行了多次优化。某些衍生物在适当的酶学测定中表现出优秀的MEK1结合亲和力,并在细胞测定中对ERK通路表现出明显的抑制效应。这些化合物还显著抑制了HEK293和RD细胞中的病毒(EV71)复制。几种化合物显示出作为病毒感染性疾病治疗剂的潜力,其中最有效的化合物18在MEK1结合测定中的IC50值为54.57 nM。
