Abstract In the current study, we designed and synthesised a novel series of 2-(2,6-dioxopiperidin-3-yl)isoquinoline-1,3(2H,4H)-dione derivatives as cereblon (CRBN) modulators. The results of the CCK8 assay revealed potent antiproliferative activity for the selected compound 10a against NCI-H929 (IC50=2.25 µM) and U239 (IC50=5.86 µM) cell lines. Compound 10a also can inhibit the TNF-α level (IC50=0
摘要 在目前的研究中,我们设计并合成了一系列新的 2-(2,6-dioxopiperidin-3-yl)isoquinoline-1,3(2 H ,4 H )-二酮衍生物作为 cereblon (CRBN) 调节剂。CCK8 测定的结果显示所选化合物10a对 NCI-H929 (IC 50 =2.25 µM) 和 U239 (IC 50 =5.86 µM) 细胞系具有有效的抗增殖活性。化合物10a还可以抑制 LPS 刺激的 PMBC 中的 TNF-α 水平 (IC 50 =0.76 µM),并且对这种正常人细胞系几乎没有毒性。TR-FRET 分析显示化合物10a对 CRBN 具有强效抑制活性(IC 50= 4.83 µM),对接研究证实10a很好地适合CRBN 的活性位点。进一步的生物学研究表明,化合物10a可以增加凋亡事件,将 NCI-H929 细胞阻滞在 G0/G1 细胞周期,并通过 CRL4
