PTH or PTHrP compounds having potent antagonistic activity at the PTH/PTHrP receptor in which at least one of the amino acid residues naturally occurring in positions 2 and 10 is replaced by tryptophane or another amino acid residue bearing an aromatic or heteroaromatic group on its side chain, and optionally at least one of the amino acid residues naturally occurring in positions 3 and 6 is further replaced by tryptophane or another amino acid residue bearing an aromatic or heteroaromatic group on its side chain, having pharmacological activity, e.g. prevention or treatment of conditions which are associated with increased plasma calcium caused by excessive release of PTH or PTHrP. |
