We report a design strategy to obtain potent DPP-4 inhibitors by incorporating salt bridge formation with Lys554 in the S1′ pocket. By applying the strategy to the previously identified templates, quinoline 4 and pyridines 16a, 16b, and 17 have been identified as subnanomolar or nanomolar inhibitors of human DPP-4. Docking studies suggested that a hydrophobic interaction with Tyr547 as well as the
我们报告了一种设计策略,通过在S1'口袋中结合Lys554与盐桥形成来获得有效的DPP-4抑制剂。通过将该策略应用于先前确定的模板,喹啉4和吡啶16a,16b和17被鉴定为人DPP-4的亚纳摩尔或纳摩尔抑制剂。对接研究表明,与Tyr547的疏水相互作用以及盐桥相互作用对于极高的效力非常重要。该设计策略对于探索具有独特结构和独特结合模式的DPP-4抑制剂的新颖设计将是有用的。
