The identification of an indoline-based compound that inhibits both 5-lipoxygenase and soluble epoxide hydrolase has opened up new possibilities for the rational design of multitarget drugs in medicinal chemistry. This compound showed promising activity in both enzymatic and cellular assays, and exhibited remarkable anti-inflammatory efficacy in vivo. Further investigation is needed to explore the potential use of this compound as an anti-inflammatory agent.
The design of multitarget drugs represents a promising strategy in medicinal chemistry and seems particularly suitable for the discovery of anti-inflammatory drugs. Here, we describe the identification of an indoline-based compound inhibiting both 5-lipoxygenase (5-LOX) and soluble epoxide hydrolase (sEH). In silico analysis of an in-house library identified nine compounds as potential 5-LOX inhibitors. Enzymatic and cellular assays revealed the indoline derivative 43 as a notable 5-LOX inhibitor, guiding the design of new analogues. These compounds underwent extensive in vitro investigation revealing dual 5-LOX/sEH inhibitors, with 73 showing the most promising activity (IC50s of 0.41 +/- 0.01 and 0.43 +/- 0.10 mu M for 5-LOX and sEH, respectively). When challenged in vivo in zymosaninduced peritonitis and experimental asthma in mice, compound 73 showed remarkable anti-inflammatory efficacy. These results pave the way for the rational design of 5-LOX/sEH dual inhibitors and for further investigation of their potential use as anti-inflammatory agents.
