  • Polypeptide having an action on the immunological system, processes for its isolation and purification, its use, agents containing this compound, and its cleavage products, their use and agents containing these products
    Patent number: 4526717
    Abstract: The invention relates to a polypeptide which can be isolated from thymus glands and has an action on the immunological system, and which has a molecular weight of 3,480, a UV absorption with a maximum at 205 to 210 nm and an isoelectric point of 3.95+0.15 and a specific aminoacid composition, the N-terminal, if appropriate, carrying an acyl group or an acylglycyl group, processes for its isolation and purification, its use, agents containing this polypeptide, and its cleavage products, their use and agents containing them.

  • New peptides and a process for their preparation
    Patent number: 4420424
    Abstract: 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.
