RO-3306是一种有效的ATP竞争性周期蛋白依赖性激酶(CDK)1抑制剂,对cdk1/cyclin B1和cdk1/cyclin A的Ki值分别为35和110 nM。
细胞周期进程受多种CDK调控。Cdk1控制细胞周期进入有丝分裂。该物质可与周期蛋白B生成双组分复合体,可磷酸化一系列底物,这些底物可协调核膜破裂、染色体凝缩、有丝分裂纺锤体组装和纺锤体组装检验点活化。
在DU145细胞中,CDK1的抑制剂RO-3306可在GI50(1 μM)下减弱BRCA1向DSB的定位,并同时抑制RAD51病灶形成。100 nM的AZ12253801和1 μM的RO-3306联合使用,前G1期DNA大幅增加,表明可诱导细胞凋亡。在活力实验中,RO-3306引起AZ12253801的剂量反应曲线明显向左偏移,相比RAD51的消耗或抑制,其GI50值减少2.4倍。50 nM浓度的AZ12253801可引起更明显的敏化作用,GI80减少13倍。作为RAD51缺失的并联效果,RO-3306并不影响PC3或LNCaP 细胞对AZ12253801的敏感性,但可致敏22Rv1细胞。
