摘要:
What are disclosed are pentapeptides, useful for influencing the maturing of T-lymphocytes, of the formulaG--K--Q--X--MwhereinG is arginine, lysine, ornithine, or homoarginine, or is an unsubstituted or substituted .omega.-aminoalkanoyl, .omega.-guanidinoalkanoyl, or .omega.-dimethylaminoalkanoyl;K is a basic amino acid such as lysine, arginine, homoarginine, or ornithine;Q is L- or D-glutamic acid, d-aspartic acid, or D-.alpha.-aminoadipic acid;X is L-valine or L-isoleucine; andM is an L- or D-aminoacid having a hydrophobic side chain, or an ester or amide of such an acid.
摘要:
What is disclosed is a method for the manufacture of LH-RH and LH-RH analogs, which comprises reacting Glu-His(DnP)-OH with the corresponding peptide having a free amino group and protected carboxy groups in a solvent as used in peptide chemistry and with the addition of 3-hydroxy-4-oxo-3,4-dihydro-1,2,3-benzotriazine (HOObt) and a carbodiimide and then splitting off the Dnp-(2,4-dinitrophenyl) group. The new method greatly reduces the degree of histidine racemization. The invention also provides a new dipeptide, i.e. Glu-His(Dnp)-OH.
摘要:
The present invention relates to peptides having strong LH-RH/FSH-RH activity, wherein Gly in the 6-position is replaced by different substituted amino acids and in the 10-position there is glycinamide or glycine in the 10-position is replaced by a NH-alkyl group with 1-3 carbon atoms or a NH-cyclopropyl group. The invention relates as well to a process for manufacturing said peptides, and to pharmaceutical preparations containing said peptides.
