Blockage of DCN1-UBE2M interaction can selectively inhibit neddylation. In this paper, the study of 3D-QSAR, molecular docking and molecular dynamics simulation studies were carried out on the piperidinylurea DCN1-UBE2M interaction inhibitors. CoMFA and CoMSIA methods for 3D-QSAR were used to build the models, whose cross-validation coefficients q² were 0.686 and 0.682, and the fitting verification coefficients r² were 0.966 and 0.931, respectively, indicating the reliability of the model and its good predictive ability. Furthermore, molecular docking was used to analyze the interaction of piperidinylurea compounds with DCN1, and the results showed that they mainly bind to the target protein through hydrogen bond interaction and hydrophobic interaction. Study on molecular dynamics simulation further understand the binding model and verify the docking results. These research provided clues for structural optimization of such compounds. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
