Multitarget anti-inflammatory drugs interfering with the arachidonic acid cascade exhibit superior efficacy. In this study, a prototype dual inhibitor of soluble epoxide hydrolase (sEH) and LTA4 hydrolase (LTA4H) with submicromolar activity toward both targets has been designed and synthesized. Preliminary structure–activity relationship studies were performed to identify optimal substitution patterns. X-ray structure analysis of a promising dual inhibitor in complex with sEH, as well as molecular docking with LTA4H provided a rationale for further optimization. Hereby, scaffold extension was successfully applied to yield potent dual sEH/LTA4H inhibitors. The spectrum of pro- and anti-inflammatory lipid mediators was evaluated in M1 and M2 macrophages, stimulated with LPS, and incubated with the most promising compound 14. The effect of 14 on the inflammatory lipid mediator profile characterizes dual sEH/LTA4H inhibitors as an interesting option for future anti-inflammatory agent investigations.
