Abstract
Exploration of the chemical space of known influenza polymerase PB2 inhibitor Pimodivir, was performed by our group. We synthesized and identified compounds 16a and 16b, two novel thienopyrimidine derivatives displaying anti-influenza A activity in the single digit nanomolar range in cell culture. Binding of these unique compounds in the influenza polymerase PB2 pocket was also determined using molecular modeling.
摘要
本课题组对已有的流感聚合酶 PB2 抑制剂 Pimodivir 进行了化学空间探索。我们合成并鉴定了两个新型噻吩并嘧啶衍生物 16a 和 16b，它们在细胞培养中显示出抗甲型流感活性，其半数抑制浓度（IC50）均在纳摩尔数量级。同时，还通过分子建模确定了这些独特化合物在流感聚合酶 PB2 口袋中的结合情况。
