摘要:
The present invention relates to a quick method for the qualitative and quantitative medical-diagnostic analysis on the protein level of the substitution of single amino acids with pathogenic and non-pathogenic effects on the organism. The medical-diagnostic analysis is performed by a combination of enzymatic or chemical cleavage of the isolated peptide, chromatographical separation of the fragments and analysis by mass spectrometry, both direct LC/MS and indirect MALDI-MS, and analysis by capillary electrophoresis. By comparing protein samples from healthy humans with those of ill humans, the method described is suitable for establishing new, as yet unknown mutations and quantifying the expression and incorporation of wild type to mutant.

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.
摘要:
Described is a peptide fragment which comprises the amino acid sequence 95-126 of ANF/CDD 1-126 (gamma-hANaP) and is formed in the kidney. The fragment urodilatin (ANF/CDD 95-126) has the following amino acid sequence: ##STR1## wherein R.sup.1 and R.sup.2 each represent further peptide fragments of ANF/CDD 1-126 (gamma-hANaP). In the amino acid sequence R.sup.1 is Thr-Ala-Pro-Arg-Ser-Leu-Arg-Arg-Ser-Ser and R.sup.2 is Asn-Ser-Phe-Arg-Tyr. Further described are processes for the preparation and/or recovery of the new peptide fragment and a medicament containing urodilatin (ANF/CDD 95-126) as well as medical indications of the medicament.
