Assay Method Information

Assay Name:  Inhibition Assay
Description:  Compounds were tested for their ability to inhibit recombinant soluble epoxide hydrolase (sEH) protein. The assay utilizes (3-Phhenyl-oxiranyl)-acetic acid cyano-(6-methoxy-naphthalen-2-yl)-methyl ester (PHOME), a sensitive substrate for sEH that can be used to monitor the activity of both human and murine enzymes. Hydrolysis of the substrate epoxide yields a highly fluorescent product, 6-methoxy-2-Naphthaldehyde, which can be monitored at excitation and emission wavelengths of 330 and 465 nm, respectively. See Wolf et al., Anal Biochem 355:71-80, 2006 PMID: 16729954. Human recombinant sEH was incubated with substrate and compounds ranging in concentration from 0.1 to 1000 nM.
