                 Application No.08/646,558                                                                           

                              carboxylic acid or amide group; said peptide being a cyclic disulfide                  
                              and comprising the amino acid residue sequence of Xaa1-Xaa2-                           
                              Asp-Xaa3 (SEQ ID NO:15), where Xaa1, Xaa2 and Xaa3 are each                            
                              independently any aromatic or hydrophobic amino acid residue with                      
                              the proviso that when Xaa1 is Lys or Arg, Xaa2 cannot be Gly or                        
                              Cys.
