Abstract
Inflammation is closely linked to the abnormal phospholipid metabolism chain of cyclooxygenase-2/microsomal prostaglandin E2 synthase-1/prostaglandin E2 (COX-2/mPGES-1/PGE2). In clinical practice, non-steroidal anti-inflammatory drugs (NSAIDs) as upstream COX-2 enzyme activity inhibitors are widely used to block COX-2 cascade to relieve inflammatory response. However, NSAIDs could also cause cardiovascular and gastrointestinal side effects due to its inhibition on other prostaglandins generation. To avoid this, targeting downstream mPGES-1 instead of upstream COX is preferable to selectively block overexpressed PGE2 in inflammatory diseases. Some mPGES-1 inhibitor candidates including synthetic compounds, natural products and existing anti-inflammatory drugs have been proved to be effective in in vitro experiments. After 20 years of in-depth research on mPGES-1 and its inhibitors, ISC 27864 have completed phase II clinical trial. In this review, we intend to summarize mPGES-1 inhibitors focused on their inhibitory specificity with perspectives for future drug development.

Abstract
PURPOSE OF REVIEW Lipid mediators including the lysophospholipids, sphingolipids and eicosanoids have long been implicated in inflammation, cancer and numerous other diseases. Over the last decade, new research suggests a role for these mediators in fibrosis. RECENT FINDINGS Recent developments in the study of fibrotic mediators have centered on lysophospholipids and eicosanoids. New research is evaluating metabolic-profiling strategies to quantitatively measure lipid mediators in human plasma. Lysophosphatidic acid receptor antagonists are currently under development with early phase trials scheduled for idiopathic pulmonary fibrosis and scleroderma dermal fibrosis. Eicosanoids have long been implicated in maintaining tissue homeostasis, and the balance of profibrotic and antifibrotic effects has drawn attention in recent years. Targeting the prostanoids, specifically PGE2 and PGI2, as well as the leukotrienes is now being considered for antifibrotic therapies. SUMMARY Lipid mediators have significant roles in many disease processes. Significant research now suggests a critical role for these mediators in the pathogenesis of fibrosis. Targeting these mediators is a promising area of drug discovery.
