Nitro-fatty acids are reactive signaling mediators that are formed when unsaturated fatty acids react with nitric oxide or nitric oxide-derived species. Nitro-fatty acids can modify specific signaling pathways via post-translational modifications of Cys residues in key regulatory proteins. One of

The effects of a peptide, BQ-788 [N-cis-2, 6-dimethyl-piperidinocarbonyl-L-gamma-methylleucyl-D-1- methoxycarbonyltryptophanyl-D-norleucine], on isolated blood vessel and small intestine were examined. In the rat aorta, BQ-788 antagonized the endothelium-dependent, ETB1 receptor-mediated relaxation due to endothelin (ET)-3 with EC50 of 3 microM. In the
