A new series of 3-substituted-4-hydroxycoumarin derivatives was designed, synthesized, and evaluated for CDK inhibiting and anticancer activities. All the synthesized target compounds showed remarkably high affinity and selectivity towards CDK1B, compared to flavopiridol, with Ki values in the low nanomolar range (Ki=0.35-0.88nM). Most of them elicited considerable inhibiting effect against CDK9T1
设计,合成并评估了一系列新的3-取代-4-羟基香豆素衍生物的CDK抑制和抗癌活性。与flavopiridol相比,所有合成的目标化合物均对CDK1B表现出极高的亲和力和选择性,Ki值在低纳摩尔范围内(Ki = 0.35-0.88nM)。它们中的大多数引起对CDK9T1的显着抑制作用(Ki = 3.26-23.45nM)。此外,所有目标化合物均针对18种类型的人类肿瘤细胞系进行了体外测试。hydr 3a,N-苯基吡唑啉衍生物6b和2-氨基吡啶基-3-甲腈衍生物8c是针对MCF-7乳腺癌细胞系的最有效抗癌剂(分别为IC50 = 0.21、0.21和0.23nM)。目标化合物3a,在MCF-7乳腺癌小鼠异种移植模型中进一步评估了6b和8c,并显示了10mg / kg剂量的体内功效。对接研究证实了CDK1B活性位点的独特结合模式,其得分高于黄酮哌啶醇。定量结构活动关系研究已经完成,揭示了0.81的高度预测力R(2)。
