with dimethylaminopropyl and fluorination of benzyl at position 6 of purine of seliciclib resulted in the formation of a derivative that potently and selectively inhibited CDK9 (26 nM vs. CDK9 and > 60-fold selectivity vs. CDK2/5/7). In comparison to seliciclib, this derivative shows lower metabolic clearance (25% lower in Clint), higher aqueous solubility and is more cytotoxic in androgen-independent
Seliciclib是一种细胞周期蛋白依赖性激酶(CDK)抑制剂,已在II期临床试验中作为抗癌剂进行了分析。本文描述了具有增强的效力,代谢稳定性,水溶性和抗增殖活性的塞塞利比布新型衍生物的合成。新的衍生物显示出新颖的CDK选择性。用二甲基氨基丙基取代嘌呤2位上的乙醇,并在seliciclib嘌呤6位上取代苄基的氟化,导致形成了一种衍生物,该衍生物有效地和选择性地抑制了CDK9(对CDK9为26 nM,对CDK2为60倍以上的选择性) / 5/7)。与seliciclib相比,该衍生物的代谢清除率较低(Cl int降低25%),在非雄激素依赖性前列腺癌细胞中具有更高的水溶性,并且具有更高的细胞毒性。 图形摘要
