Specialized pro-resolving lipid mediators (SPMs) are natural bioactive agents actively involved in inflammation resolution. SPMs act when uncontrolled inflammatory processes are developed, for instance, in patients of COVID-19 or other diseases. The so-called resolution pharmacology aims at developing new treatments based on the use of SPMs as agonists, which promote inflammation resolution without unwanted side effects.

Cyclooxygenases (COXs) are the enzymes responsible for the biosynthesis of prostaglandins, eicosanoids that play a major role in many physiological processes. Particularly, prostaglandins are known to trigger inflammation, and COX-2, the enzyme isoform associated with this inflammatory response, catalyzes the cyclooxidation of arachidonic acid, leading to prostaglandin G2. For this reason, COX-2 has been a very important pharmacological target for several decades now.

Ebselen is a potent competitive inhibitor of the active form of rabbit 15-lipoxygenase, an enzyme involved in many inflammatory diseases. Light-induced Z-to-E isomerization of the ebselen-like 2-(3-benzylidene)-3-oxo-2,3-dihydrobenzo[b]thiophene-7-carboxylic acid methyl ester (BODTCM) molecule was used to convert the weak (Z)-BOTDCM inhibitor into the (E)-isomer with much higher inhibitory capacity. In this study, the binding modes of ebselen, (E)-BOTDCM and (Z)-BOTDCM, have been analyzed to provide molecular insights on the inhibitory potency of ebselen and on the geometric-isomer specificity of (E)- and (Z)-BOTDCM inhibitors.
