Pyrazolopyridazine 1a was identified in a high-throughput screening carried out by BASF Bioresearch Corp. (Worcester, MA) as a potent inhibitor of CDK1/cyclin B and shown to have selectivity for the CDK family. Analogues of the lead compound have been synthesized and their antitumor activities have been tested. A molecular model of the complex between the lead compound and the CDK2 ATP binding site
在由BASF Bioresearch Corp.(马萨诸塞州伍斯特)进行的高通量筛选中鉴定出
吡唑并
哒嗪1a为有效的CDK1 / cyclin B
抑制剂,并显示出对CDK家族具有选择性。已合成了
铅化合物的类似物,并测试了其抗肿瘤活性。使用构象搜索和自动对接技术的组合,已建立了先导化合物和CDK2
ATP结合位点之间的复合物的分子模型。所得复合物的稳定性已通过分子动力学模拟进行了评估,并且在拟议的化合物1a结合方式的基础上,对合成的类似物所获得的实验结果进行了合理化处理。
