Lipid chemical mediator resolvins with highly potent anti-inflammatory activity can be leads to develop novel anti-inflammatory drugs; however, they are unstable in oxygen due to their characteristic polyunsaturated structures. To solve the problem, CP-RvE2 has been designed and synthesized in which the cis-olefin of RvE2 was replaced with a cyclopropane. CP-RvE2s were much more stable than RvE2 against autoxidation and equipotent or more potent than RvE2. CP-RvE2s were successfully identified as stable equivalents of RvE2.
