A series of novel 3-(thiophen-2-ylthio)pyridine derivatives as insulin-like growth factor 1 receptor (IGF-1R) inhibitors was designed and synthesized. IGF-1R kinase inhibitory activities and cytotoxicities against HepG2 and WSU-DLCL2 cell lines were tested. For all of these compounds, potent cancer cell proliferation inhibitory activities were observed, but not through the inhibition of IGR-1R. Selected compounds were further screened against various kinases. Typical compound 22 (50% inhibitory concentration [IC ] values, HepG2: 2.98 ± 1.11 μM and WSU-DLCL2: 4.34 ± 0.84 μM) exhibited good inhibitory activities against fibroblast growth factor receptor-2 (FGFR2), FGFR3, epidermal growth factor receptor, Janus kinase, and RON (receptor originated from Nantes), with IC values ranging from 2.14 to 12.20 μM. Additionally, the cell-cycle analysis showed that compound 22 could arrest HepG2 cells in the G1/G0 phase. Taken together, all the experiments confirmed that the compounds in this series were multitarget anticancer agents worth further optimizing.
设计并合成了一系列新型 3-(噻吩-2-基硫代)吡啶衍生物作为胰岛素样生长因子 1 受体 (IGF-1R) 抑制剂。测试了这些化合物对 HepG2 和 WSU-DLCL2 细胞系的 IGF-1R 激酶抑制活性和细胞毒性。对于所有这些化合物,都观察到了很强的癌细胞增殖抑制活性,但不是通过抑制 IGF-1R 实现的。选择的化合物进一步针对各种激酶进行了筛选。典型的化合物 22(对 HepG2 的 50%抑制浓度 [IC ] 值为 2.98 ± 1.11 μM,对 WSU-DLCL2 的为 4.34 ± 0.84 μM)对成纤维细胞生长因子受体 2 (FGFR2)、FGFR3、表皮生长因子受体、Janus 激酶和 RON(源自 Nantes 的受体)表现出良好的抑制活性,IC 值范围为 2.14 至 12.20 μM。此外,细胞周期分析表明,化合物 22 可以使 HepG2 细胞停滞在 G1/G0 期。总之,所有实验都证实,该系列化合物是值得进一步优化的多靶抗癌药物。
