  report the results of our expanded SAR investigations that focused on modifications to the aryl carbinol group of this series. Guided by the X-ray cocrystal structure of compound 1 bound to hGKRP, we identified several potent GK–GKRP disruptors bearing a diverse set of functionalities in the aryl carbinol region. Among them, sulfoximine and pyridinyl derivatives 24 and 29 possessed excellent potency

To develop a broad-spectrum inhibitor of influenza to combat the problem of drug resistance, we previously identified the highly conserved E339...R416 salt bridge of the nucleoprotein trimer as a target and compound 1 as an inhibitor disrupting the salt bridge with an EC50 = 2.7 μM against influenza A (A/WSN/1933). We have further modified this compound via a structure-based

  流感感染中的抗病毒药物耐药性已成为对公共卫生的主要威胁。为了开发广谱的流感抑制剂来解决耐药性问题，我们之前确定了高度保守的核蛋白三聚体E339 ... R416盐桥为靶标，化合物1为通过EC50破坏盐桥的抑制剂甲型流感病毒= 2.7μM（A / WSN / 1933）。我们通过基于结构的方法进一步修饰了该化合物，并进行了抗病毒活性筛选，以鉴定化合物29和30的EC50值分别为110和120 nM，并且没有可测量的宿主细胞毒性。与临床使用的神经氨酸酶抑制剂相比，这两种化合物对耐药性A型流感病毒株和B型流感病毒显示出更好的活性，
