anticancer drugs. Flavonoids are reported to be effective CK2 inhibitors. Herein, based on structural trimming of flavonoids, a series of chromone-2-aminothiazole derivatives (1a-d, 2a-g, 4a-j, 5a-k) were designed and synthesized by hybridizing the chromone skeleton with 2-aminothiazole scaffold. Among these compounds, compound 5i was the most effective CK2 inhibitor (IC50 = 0.08 μM) and possessed potent anti-proliferative

抑制剂 (IC 50 = 0.08 μM),对 HL-60 肿瘤细胞具有有效的抗增殖活性 (IC 50 = 0.25 μM)。细胞热位移测定 (CESTA) 证实5i直接与CK2结合,还模拟了5i对CK2的可能结合模式。进一步的研究表明,5i诱导 HL-60 细胞凋亡并阻止细胞周期。最后,weSTern-blot分析显示5i可以抑制CK2的下游,包括α-catenin/Akt通路和PARP/Survivin通路。
