Abstract: The invention provides parstatin peptides, particularly a mammalian parstatin peptide including amino acids 1-26 of full length mammalian parstatin, preferably a human parstatin. The invention provides parstatin peptides in appropriate pharmaceutical carriers and formulated for administration. The invention provides for the use of the peptide for example as a medicament or for the preparation of a medicament. The invention provides methods of use for parstatin peptides including for inhibition of angiogenesis, for example for inhibition of ocular angiogenesis, for methods of cardioprotection, and for methods of prevention and treatment of myocardial ischemia-reperfusion injury.

Abstract: Bioactive peptides that have a molecular weight of approximately 4.5 kDa and correspond to amino-terminal fragments of protease-activated receptor-1 (PAR-1), which are cleaved and released upon the proteolytic activation of PAR-1 by proteases including, but not limited to, thrombin in humans and animals are disclosed. Such synthetic or recombinantly expressed or endogenously produced or chimeric synthetic peptides that are active in vitro and in vivo and modulate endothelial cell functions and physiological and pathological processes are named herein as parstatin. Parstatin peptides, fragments, analogs, derivatives have the ability to inhibit endothelial cell growth, migration and differentiation, to induce endothelial cell apoptosis, to block angiogenesis and have cardioprotective effects in ischemia/reperfusion injury. Methods for treating angiogenesis-related diseases and endothelium dysfunction-related cardiovascular diseases are disclosed.
