An evaluation of the inflammatory enzymatic interactions related to pulmonary function can help identify biomarkers for interventions or prophylactic measures to improve patient prognosis. This study aimed to determine the effect of epoxide hydrolase inhibition by GSK2256294 in different pulmonary inflammation models. A secondary search was performed using Medline/PubMed, Web of Science, SciELO, Cochrane Library, Embase, Academic Google, and gray literature by two independent reviewers, who analyzed the methodological quality and consistency of the data. Different variables were compared using a meta-analysis. A total of 86 studies were found, 4 of which were selected from the gray literature. Based on the eligibility criteria, two clinical and one preclinical studies were evaluated. GSK2256294 inhibited the soluble epoxide hydrolase enzyme in both clinical and preclinical models, exhibiting greater effectiveness in clinical studies and contributing to the anti-inflammatory activity mediated by the eicosatrienoic pathway by reducing the levels of dihydroxyeicosatrienoic acids and leukotoxin-diol. Overall, GSK2256294 was identified as a promising drug for controlling the deleterious manifestations of lung inflammation. Further clinical and preclinical studies are required to ensure consistency among the evidence and identify other biological activities mediated by GSK2256294.
