Hydrolases (Ether)

Soluble expoxide hydrolase (sEH; EC 3.3.2.10) is a key enzyme in the metabolism of eicosanoid epoxides, including epoxyeicosatrienoic acids (EETs)  and of leukotoxin (LTX). EETs, endothelium-derived hyperpolarizing factors, exhibit potentially beneficial properties, including anti-inflammatory effects and vasodilation. The enzyme is a bifunctional homodimeric complex located in both cytosol and peroxisomes with hydrolase and phosphatase activity[1]. GSK2256294A (Axon 2220) is a potent, selective inhibitor of sEH, and attenuates cigarette smoke-induced inflammation by both inhibiting its initiation and/or maintenance and promoting its resolution. 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[2].
