compound 1, we succeeded in obtaining several compounds showing enhanced inhibitory activity both on CDKs and on tumor cells and displaying improved physical properties and pharmacokinetic behavior. Our study led to the identification of compound 59 as a highly potent, orallybioavailable CDK inhibitor that exhibited significant in vivo efficacy on the A2780 ovarian carcinoma xenograft model. The demonstrated
由破坏细胞周期的机制破坏所介导的异常增殖实际上是所有癌细胞的标志。靶向针对细胞周期蛋白依赖性激酶(CDK)和细胞周期蛋白(Cy)之间的复合物并抑制其活性的化合物被认为是有前途的抗肿瘤药物,可补充现有疗法。扩展了吡唑并[4,3- h ]喹唑啉化学类别,使其面向三个可变点的发展,从而导致了一系列能够在体外和体内抑制CDK的化合物。从CDK选择性但难溶的打击化合物1开始,我们成功地获得了几种对CDKs和肿瘤细胞均显示出增强抑制活性并显示出改善的物理性质和药代动力学行为的化合物。我们的研究导致将化合物59鉴定为高效,口服生物利用的CDK抑制剂,该化合物在A2780卵巢癌异种移植模型上显示出显着的体内功效。化合物59对癌细胞系的作用机理及其在体内抑制肿瘤生长的能力使该化合物作为潜在的抗肿瘤药非常有趣。
