Abstract:
PROBLEM TO BE SOLVED: To obtain a protein which can neutralize the action of TNFα (tumor necrusis factor α). SOLUTION: This protein has molecular weight of about 42,000 daltons measured by SDS gel electrophoresis and has at the N-terminus an amino acid sequence; Xaa Thr Pro Tyr Ala Pro Glu Pro Gly Ser Thr Cys Arg Leu Arg Glu (Xaa is H, phenylalanine residue (Phe) or an amino acid sequence; Ala Phe, Val Ala Phe, Gln Val Ala Phe, Ala Gln Val Ala Phe, Pro Ala Gln Val Ala Phe or Leu Pro Ala Gln Val Ala Phe), and a mutein is obtained by subjecting the protein having the TNFα suppressing action to a proper substitution, deletion or addition of an amino acid or peptide or the change of a glycoside group without strongly lowering the TNFα suppressing action.

PROBLEM TO BE SOLVED: To obtain a protein which can neutralize the action of TNFα. SOLUTION: The protein has a molecular weight of about 42,000 daltons in the first glycosylated form and has at the N-terminus an amino acid sequence; Xaa Thr Pro Tyr Ala Pro Glu Pro Gly Ser Thr Cys Arg Leu Arg Glu (Xaa is H, phenylalanine residue (Phe) or an amino acid sequence; Ala Phe, Val Ala Phe, Gln Val Ala Phe, Ala Gln Val Ala Phe, Pro Ala Gln Val Ala Phe or Leu Pro Ala Gln Val Ala Phe), and the protein and a mutein obtained by the proper substitution, deletion or addition of an amino acid or peptide for/ from/or to/the protein or the change of a glycoside group without strongly lowering the action of the protein are used for suppressing the abnormal increase in the TNF-α.
Abstract:
The invention relates to peptidic substances, to the production of said substances and to their use as complement inhibitors. In particular, the invention relates to substances with a guanidine or amidine radical as the terminal group, especially inhibitors of the complement proteases C1s and C1r.
Abstract:
Described are glycosylated, partially glycosylated or unglycosylated polypeptides with the amino-acid sequence given in the sequence protocol and in which up to 10 amino acid groups can be replaced by other, naturally occurring, amino acids. The peptides are suitable for use in treating illnesses.
Abstract:
Peptide substances, their preparation and their use as complement inhibitors are described. These are in particular substances having a guanidine or amidine radical as a terminal group. In particular, inhibitors of the complement proteases C1s and C1r are described.
