GSK2256294A is a potent, reversible, tight binding inhibitor of isolated recombinant human sEH (soluble epoxide hydrolase) (IC50 = 27 pM; t1/2 = 121 min) and displays potent inhibition against the rat (IC50 = 61 pM) and murine (IC50 = 189 pM) orthologs of sEH.IC50 value: 27 pMTarget: sEHin vitro: GSK2256294A also displays potent cellular inhibition (IC50 = 0.66 nM) of sEH in an assay developed using a cell line transfected with the human sEH enzyme. [1]in vivo: A novel, potent, selective inhibitor of recombinant human, rat and mouse sEH, GSK2256294A, exhibits potent cell-based activity, a concentration-dependent inhibition of the conversion of 14,15-EET to 14,15-DHET in human, rat and mouse whole blood, and a dose-dependent increase in the LTX/LTX diol ratio in rat plasma following oral administration. Mice receiving 10 days of cigarette smoke exposure concomitant with oral administration of GSK2256294A exhibits significant, dose-dependent reductions in pulmonary leukocytes and keratinocyte chemoattractant levels. Mice receiving oral administration of GSK2256294A following 10 days of cigarette smoke exposure exhibited significant reductions in pulmonary leukocytes compared to vehicle-treated mice.

In vitro and in vivo characterization of a novel soluble epoxide hydrolase inhibitor
Prostaglandins Other Lipid Mediat 2013 Jul-Aug;104-105:25-31.PMID:23434473DOI:10.1016/j.prostaglandins.2013.02.001.
Soluble epoxide hydrolase (sEH, EPHX2) metabolizes eicosanoid epoxides, including epoxyeicosatrienoic acids (EETs) to the corresponding dihydroxyeicosatrienoic acids (DHETs), and leukotoxin (LTX) to leukotoxin diol (LTX diol). EETs, endothelium-derived hyperpolarizing factors, exhibit potentially beneficial properties, including anti-inflammatory effects and vasodilation. A novel, potent, selective inhibitor of recombinant human, rat and mouse sEH, GSK2256294A, exhibited potent cell-based activity, a concentration-dependent inhibition of the conversion of 14,15-EET to 14,15-DHET in human, rat and mouse whole blood in vitro, and a dose-dependent increase in the LTX/LTX diol ratio in rat plasma following oral administration. Mice receiving 10 days of cigarette smoke exposure concomitant with oral administration of GSK2256294A exhibited significant, dose-dependent reductions in pulmonary leukocytes and keratinocyte chemoattractant (KC, CXCL1) levels. Mice receiving oral administration of GSK2256294A following 10 days of cigarette smoke exposure exhibited significant reductions in pulmonary leukocytes compared to vehicle-treated mice. These data indicate that GSK2256294A attenuates cigarette smoke-induced inflammation by both inhibiting its initiation and/or maintenance and promoting its resolution. Collectively, these data indicate that GSK2256294A would be an appropriate agent to evaluate the role of sEH in clinical studies, for example in diseases where cigarette smoke is a risk factor, such as chronic obstructive pulmonary disease (COPD) and cardiovascular disease.
Designing a Small Fluorescent Inhibitor to Investigate Soluble Epoxide Hydrolase Engagement in Living Cells
ACS Med Chem Lett 2022 Jun 14;13(7):1062-1067.PMID:PMC9290038DOI:10.1021/acsmedchemlett.2c00073.
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. Furthermore, the inhibitor can be used to visualize sEH in sEH-transfected HEK293 cells and in primary mouse astrocytes by fluorescence microscopy.
