Taking the dual FABP 4/5 inhibitor RO6806051 and FABP4 inhibitor XU17 as the lead compounds, twenty new quinoline derivatives as dual FABP4/5 inhibitors were designed and synthesized according to the reported RO6806051/FABP5 crystal complex and XU17/FABP4 crystal complex, then confirmed by 1H NMR, 13C NMR and high-resolution mass spectra (HRMS). All the target compounds were evaluated for their inhibitory activity against FABP4 and FABP5 via the 8-anilino- naphthalene-1-sulfonic acid (1,8-ANS) displacement assay. The results showed that the target compound 2-(2-(6-chloro- 4-(2-chlorophenyl)quinolin-2-yl)phenyl)acetic acid (11a) exhibited strong inhibitory activity against FABP4 (IC50: 4.50 μmol/L) and FABP5 (IC50: 3.90 μmol/L).
Key words: FABP4/5 inhibitors; fusion strategy; quinoline; synthesis
