2088162 9202542 PCTABS00010 A peptide having a glycoprotein hormone (ant)agonistic activity, comprising at least 2 partial peptides selected from (1) a partial peptide having an amino acid sequence comprising TDSDS based on the amino acids (92, 88, 89, 90 and 91) of the .beta.-chain of the glycoprotein hormone hFSH or a corresponding sequence of another glycoprotein hormone and/or another animal species, (2) a partial peptide having an amino acid sequence occurring in the .alpha.-chain of glycoprotein hormones and comprising SRAY, (3) a partial peptide having an amino acid sequence comprising TRDL based on the amino acids (34-37) of the .beta.-chain of the glycoprotein hormone hFSH or a corresponding sequence of another glycoprotein hormone and/or another animal species, and (4) a partial peptide having an amino acid sequence comprising AHASTA, derived from the amino acids (82 - 87) of the .alpha.-chain of the human glycoprotein hormones by replacing the cysteines by alanines, or a corresponding sequence of a glycoprotein hormone of another animal species, which partial peptides can be linked together by bridge groups, and variants and derivatives having a glycoprotein hormone agonistic or antagonistic activity.
