Sterculic acid is a cyclopropene fatty acid with numerous biological activities. In this study we demonstrate that sterculic acid is a potent inhibitor of endoplasmic reticulum (ER) stress and related inflammation caused by 7-ketocholesterol (7KCh). 7KCh is a highly toxic oxysterol suspected in the pathogenesis of various age-related diseases such as atherosclerosis, Alzheimer’s disease and age-related macular degeneration. Sterculic acid demonstrated to be 5–10 times more effective than other anti-inflammatory fatty acids at inhibiting 7KCh-mediated inflammatory responses in cultured cells. In vivo, sterculic acid was effective at inhibiting the formation of choroidal neovascularization (CNV) in the laser-injury rat model. Our data suggests that sterculic acid may be useful in treating CNV in certain forms of age-related macular degeneration.
