摘要: This invention relates to a group of peptides which are, or are related to, platelet aggregation inhibitors isolated and purified from various snake venoms. The instant platelet aggregation inhibitors inhibit (a) binding of Fg or vWF to GPIIb-IIIa more than (b) binding of vitronectin to vitronectin receptor or fibronectin to fibronectin receptor. The peptides are useful as therapeutic agents for the treatment of, and prevention of, platelet-associated ischemic disorders.

摘要: Methods and compositions are provided for treating several acute disease states associated with smooth muscle cell proliferation as well as the chronic process of atherogenesis utilizing oligopeptides corresponding to regions of the PDGF receptor protein. The oligopeptides can be used to block PDGF binding and activation for numerous applications, and can serve as immunogens to raise receptor-specific antibodies.
