Designing a Small Fluorescent Inhibitor to Investigate Soluble Epoxide Hydrolase Engagement in Living Cells.

ABSTRACT: Soluble epoxide hydrolase (sEH) is a promising target for a number of inflammation-related diseases. In addition, inhibition of sEH has been shown to reduce neuroinflammation, which plays a critical role in the development of central nervous system (CNS) diseases such as Alzheimer's disease. In this study, we present the rational design of a small fluorescent sEH inhibitor. Starting from the clinical candidate GSK2256294A, we replaced the triazine moiety with the 4-chloro-7-nitrobenzo-2-oxa-1,3-diazole (NBD-Cl) fluorophore. The resulting fluorescent sEH inhibitor displayed excellent potency in an in vitro enzyme activity assay (IC₅₀ < 2 nM). The developed inhibitor is applicable in a NanoBRET-based assay system suitable for studying sEH target engagement in living cells. Further
