  发现3-（噻吩/噻唑-2-基硫基）吡啶衍生物作为多靶点抗癌药

  摘要：

  设计并合成了一系列新颖的3-（噻吩/噻唑-2-基硫基）吡啶衍生物，作为IGF-1R酪氨酸激酶抑制剂。测试了所有目标化合物对五种癌细胞系（K562，Hep-G2，HCT-116，WSU-DLCL2和A549）的IGF-1R激酶抑制活性和细胞毒性。尽管所有这些化合物均表现出中度至有效的癌细胞增殖抑制活性（最有效的化合物43的IC 50为50对WSU-DLCL2细胞系的检测值为1.3±0.9μM），未观察到IGF-1R抑制作用。为了鉴定这些类似物的确切靶标，进一步筛选了所选化合物的各种激酶。结果表明该系列化合物可通过抑制各种激酶（包括FGFR 3，EGFR，JAK和RON）发挥其抗癌活性。此外，化合物43在Hep-G2细胞上的细胞周期分析显示，细胞周期停滞在G1 / G0期。所有实验都验证了3-（噻吩/噻唑-2-基硫基）吡啶类似物作为多靶点抗癌药的潜力。
