    摘要: A peptide having the amino acid sequence H2N—X1—R—X3—X2—COOH  (formula I) wherein X1 is either zero or X1 and/or X2 are a residue representing at least five amino acid residues (symbolized in the one letter amino acid code), preferably naturally occurring amino acids, with the proviso that X1 and/or X2 contain at least one basic amino acid residue immediately followed by a hydrophobic amino acid residue and X1 and/or X2 contain at least one glutamine residue.

    摘要: The invention relates to a peptide from human blood, designated as hPTH-(1-37), the structure of which was elucidated for the purpose of the diagnostic, medical and commercial utilization thereof. The isolation of a fragment hPTH-(38-84) proves the existence of the hPTH-(1-37). A removal of amino-terminal amino acids from the hPTH fragment-(1-37) reduces its biological activity. The hPTH-(1-37) circulating in the blood is identical with the synthetic reference substance hPTH-(1-37), however not with fragments such as hPTH-(1-33), hPTH-(1-34) or hPTH-(1-38). The molecule form hPTH-(1-37) has been proven by mass spectrometry (plasma desorption method). A different biological activity and differences in the three-dimensional peptide structure of the hPTH fragment-(1-37) in comparison to other hPTH fragments furnish evidence of that this fragment is the preferential natural peptide of the parathormone family which should be used for the treatment of diseases of the parathyroid, circulatory system, respiratory system, male genital organ and kidneys.
