Abstract
Background: Thienopyrimidinone is a newly designed, selective fibroblast growth factor receptor 1 (FGFR1) inhibitor with an excellent anticancer effect.
Objective: The goal of the present study was to design and synthesize better FGFR1 inhibitors through modifications of the lead compound thienopyrimidinone.
Methods: In the present study, a series of C-2 substituted derivatives of thienopyrimidinone, namely L1–L16, were synthesized, and their inhibitory effects on FGFR1 were evaluated. The anti-proliferative activities of these compounds were assessed by MTT assay.
Results: Among the novel derivatives, L11 was found to exert remarkable FGFR1 inhibitory activity (79.93% at 10 µM) and anti-proliferative activity, with IC50 values of 2.1, 2.5, and 3.5 M in the FGFR1-overexpressing cell lines, H460, HT-1197, and B16F10, respectively.
Conclusion: Our newly synthesized thienopyrimidinone derivatives may be candidate FGFR1 inhibitors for future development as novel anticancer agents.
Keywords: FGFR1, inhibitor, thienopyrimidinone, design, synthesis, anticancer.
