Abstract:
Resolvins (Rvs), unsaturated fatty acid metabolites are a new type of anti-inflammatory lipid mediator that promotes inflammation resolution, so that these compounds can be efficient leads for developing new anti-inflammatory drugs. We have previously developed a cyclopropane (CP) congener of resolving E2 (RvE2), i.e., CP-RvE2, as a stable equivalent of RvE2. In this study, based on the stable equivalent of CP-RvE2, we designed and synthesized AP-β-CP-RvE2, in which an azidopropoxy (AP) group was introduced into the 5-, 18-, or 20-position of CP-RvE2, as potential chemical probes. We found that among them, 5-AP-β-CP-RvE2 had anti-inflammatory activity same as RvE2, suggesting its potential utility as a chemical probe.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
