identification of a potent and novel CDK2 inhibitor, which exhibited an unusual mode of interaction with the kinase binding motif. With the aid of X-ray crystallography and modelling, a medicinal chemistry strategy was implemented to probe the interactions seen in the crystal structure and to establish SAR. A fragment-based approach was also considered but a different, more conventional, binding mode was observed
针对pCDK2 / cyclin A的晶体结构的虚拟筛选导致鉴定出了有效的新型CDK2抑制剂,该抑制剂表现出与激酶结合基序相互作用的异常模式。借助X射线晶体学和建模,实施了一种药物化学策略,以探查晶体结构中的相互作用并建立SAR。还考虑了基于片段的方法,但是观察到了不同的,更常规的结合模式。使用合理的设计策略,通过对CDK2结合模式的晶体学验证,提高了对GSK-3beta的化合物选择性。
