15D-PGJ2

15-Deoxy-Δ12,14-PGJ2 (15d-PGJ2) is a cyclopentenone prostaglandin that features an electrophilic, α, β-unsaturated ketone (an enone) in the cyclopentenone ring. 15-Deoxy-Δ-12,14-prostaglandin J2 is one of the cyPGs whose functions in inflammation, cell proliferation, survival, and apoptosis have been documented. 15-Deoxy-Δ-12,14-prostaglandin J2 activates PPARδ in a dose-dependent manner. 15-Deoxy-Δ-12,14-prostaglandin J2 activates PPARδ’s transcriptional activity through formation of a covalent adduct between its endocyclic enone at C9 and Cys249 in the receptor’s ligand-binding domain.
