Short peptides useful for treatment of ischemia/reperfusion injury and other tissue damage conditions associated with nitric oxide and its reactive species

摘要

This invention discloses isolated short peptides comprising the amino acid sequence Cys-Glu-Phe-His (CEFH; SEQ ID NOS: 1 and 15) and analogs thereof as well as compositions comprising CEFH peptides and analogs thereof. The CEFH peptides disclosed herein are effective in mediating the denitration of 3-nitrotyrosines (3-NT) in cellular proteins thereby preventing tissue damage associated with excess nitric oxide (NO) and its reactive species. The CEFH peptides disclosed herein are useful in the treatment of ischemia/reperfusion (I/R) injury and other disorders.
