concurrent CK2 along with cancer stem cell (CSC) inhibitory activities are rare in a single small molecule. Herein, a series of 5-(3-chlorophenylamino)benzo[c][2,6]naphthyridine derivatives were synthesized using a known CK2 inhibitor, silmitasertib (CX-4945), as the lead compound. Among the resulting compounds, 1c exhibited stronger CK2 inhibitory activity with higher Clk2/CK2 selectivity than CX-4945
多功能实体最近对于开发抗癌化疗药物具有吸引力。但是,在单个小分子中很少有具有并发CK2和癌症干细胞(CSC)抑制活性的实体。在此,使用已知的CK2抑制剂西米塔塞替尼(Cilmitasertib(CX-4945))作为前导化合物合成了一系列5-(3-氯苯基氨基)苯并[ c ] [2,6]萘啶衍生物。在所得化合物中,1c与CX-4945相比具有更强的CK2抑制活性和更高的Clk2 / CK2选择性。明显地,1c可以调节Akt1(ser129)-GSK-3β(ser9)-Wnt /β-catenin信号通路并抑制茎标记ALDH1A1,CSC表面抗原和茎基因的表达,显示出强大的CSC抑制活性。此外,与CX-4945钠盐相比,1c还显示出优异的药代动力学和抗肿瘤活性,且无明显毒性。1c的良好抗增殖和抗肿瘤活性,对CK2的高抑制选择性以及对癌细胞干性的有效抑制作用使该分子成为治疗癌症的候选药物。
