Molecular Modeling and Design Studies of Purine Derivatives as Novel CDK2 Inhibitors.

ABSTRACT: Cyclin-dependent kinase 2 (CDK2) is a potential target for treating cancer. Purine heterocycles have attracted particular attention as the scaffolds for the development of CDK2 inhibitors. To explore the interaction mechanism and the structure⁻activity relationship (SAR) and to design novel candidate compounds as potential CDK2 inhibitors, a systematic molecular modeling study was conducted on 35 purine derivatives as CDK2 inhibitors by combining three-dimensional quantitative SAR (3D-QSAR), virtual screening, molecular docking, and molecular dynamics (MD) simulations. The predictive CoMFA model (q² = 0.743, r pred 2 = 0.991), the CoMSIA model (q² = 0.808, r pred 2 = 0.990), and the Topomer CoMFA model (q² = 0.779, r pred 2 = 0.962) were obtained. Contour maps revealed that the electrostat
