    摘要: An assay for screening snake venom for the presence or absence of platelet aggregation inhibitors (PAIs) based on specific receptor binding is described. Using this assay, the identification and characterization of PAIs in a wide range of snake venom samples was accomplished. The isolated and purified PAI from several of these active snake venoms is described and characterized. In addition, PAIs lacking the Arg-Gly-Asp (RGD) adhesion sequence but containing K*-(G/Sar)-D wherein K* is a modified lysyl residue of the formula R.sup.1.sub.2 N(CH.sub.2).sub.4 CHNHCO-- wherein each R.sup.1 is independently H, alkyl(1-6C) or at most one R.sup.1 is R.sup.2 --C.dbd.NR.sup.3 wherein R.sup.2 is H, alkyl(1-6C), phenyl or benzyl, or is NR.sup.4.sub.2 in which each R.sup.4 is independently H or alkyl(1-6C) and R.sup.3 is H, alkyl(1-6C), phenyl or benzyl, or R.sup.2 --C.dbd.NR.sup.3 is a radical selected from the group consisting of: ##STR1## where m is an integer of 2-3, and each R.sup.5 is independently H or alkyl(1-6C); and wherein one or two (CH.sub.2) may be replaced by O or S provided said O or S is not adjacent to another heteroatom are prepared and shown to specifically inhibit the binding of fibrinogen or von Willebrand Factor to GP IIb-IIIa.

    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.
