complex with cyclin A in G1/S phase of the cell cycle has been shown to promote selective apoptosis of cancer cells through the E2F1 pathway. An alternative approach to catalytic inhibition is to target the substrate recruitment site also known as the cyclin binding groove (CBG) to generate selective non-ATP competitive inhibitors. The REPLACE strategy has been applied to identify fragment alternatives and
已经显示在细胞周期的G1 / S期与细胞周期蛋白A复合的细胞周期蛋白依赖性激酶2(CDK2)的抑制作用通过E2F1途径促进癌细胞的选择性凋亡。催化抑制的另一种方法是靶向底物募集位点,也称为细胞周期蛋白结合槽(CBG),以产生选择性的非ATP竞争性抑制剂。REPLACE策略已用于鉴定片段的替代物,取代的苯甲酸衍生物被评估为有前途的支架,可提供模拟关键肽决定簇的适当功能。描述了片段连接的抑制性肽(FLIP),其有效地抑制CDK2 /细胞周期蛋白A和CDK4 /细胞周期蛋白D1两者,并且具有初步的抗肿瘤活性。
