Synonyms: compound 22b [PMID: 31436984]
Compound class: Synthetic organic
Comment: SWE101 is a soluble epoxide hydrolase (sEH; EPHX2) inhibitor that selectively, and competitively targets the enzyme's phosphatase activity [2]. Its structure was developed from the scaffold of the NSAID oxaprozin which exhibits weak sEH-phosphatase inhibitory activity [1]. SWE101 is a tool compound that was designed to aid investigations of the physiological and pathophysiological role of sEH phosphatase activity in vivo.

Bioactivity Comments
SWE101 inhibits the phosphatase activity of human and rat sEH, but neither the hydrolase or phosphatase activities of mouse sEH are inhibited [2]. It also exhibits low potency COX enzyme inhibitory activity. At a concentration of 10 μM SWE101 is inactive at PPARs (α, β/δ), FXR, LXRα and LXRβ. SWE101 inhibits the phosphatase activity of the full-length human enzyme with IC50 of 9 μM. This is a reduced potency compared to the IC50 determined for inhibition of the isolated phosphatase domain-containing N-terminal.
