Abstract: A synthetic polypeptide having at least about 10% of the immunological activity of biologic heat-stable enterotoxin of E. coli. The synthetic polypeptide includes at least 14 amino acids in the sequence, from amino-terminus to carboxy-terminus, represented by the formula: CysCysGluLeuCysCysTyr-(Asn)ProAlaCysAla(Thr)GlyCysAsn(Tyr) wherein the amino acid in parentheses may replace the immediately preceding amino acid residue, and at least one intramolecular disulfide bond formed between the Cys residues. The Cys residues that are not part of the intramolecular disulfide bond can be replaced by other amino acid residues or be bonded to substituent moieties. The polypeptides can be a monomeric or multimeric material containing an intramolecular, intrapolypeptide and/or an intramolecular, interpolypeptide cystine disulfide bond.

Abstract: A composition and method for treating thrombotic disorders. The composition comprises a peptide comprising an amino acid sequence corresponding to the sequence of the amino acid residues in the EGF domain of Factor IX, or a subsequence thereof. Such peptides compete with coagulation Factors IX and IXa for endothelial binding cites and thereby inhibit thrombosis formation.
