pharmacophore has been extensively studied. However, its 2,6-substituted derivatives are rarely reported. In the present study, eighteen 2,6-substituted thieno[3,2-d]pyrimidine derivatives containing electrophilic warheads were designed based on the first known Fibroblast growth factor receptor-4 (FGFR4) inhibitor Blu9931. Unexpectedly, all of the derivatives exhibited negligible activity against FGFR4. However
噻吩并 [3,2-d] 嘧啶作为一种有效的药效团已被广泛研究。然而,其 2,6-取代衍生物却鲜有报道。在本研究中,基于第一个已知的成纤维细胞生长因子受体-4 (FGFR4) 抑制剂 Blu9931,设计了 18 种含有亲电弹头的 2,6-取代的噻吩并 [3,2-d] 嘧啶衍生物。出乎意料的是,所有衍生物对 FGFR4 的活性都可以忽略不计。然而,大多数目标化合物对四种人类癌细胞系表现出抗增殖活性,包括 A431、NCI-H1975、Ramos 和 SNU-16。化合物 12 对上述四种细胞系显示出最有效的抗增殖活性,IC50 值分别为 1.4 μM、1.2 μM、0.6 μM 和 2.6 μM。此外,12对MDA-MB-221的抗增殖活性证明12对某些肿瘤细胞系具有选择性。此外,基于实验数据讨论了初步的构效关系分析。
