The present invention provides a composition comprising an interferon-beta (IFN-beta) protein of which at least 80% is deamidated, a deamidated IFN-beta 1a protein, methods of producing deamidated proteins, and therapeutic uses of such compositions and deamidated IFN-beta 1a proteins.

IFN beta protein analogs

The present invention relates to IL-6 antagonist peptides, isolatable from a peptide library through the two-hybrids system by their ability to bind to the intracellular domain of gp130 and containing at least 5 amino acids. In particular, such peptides comprise the amino acid sequence SEQ ID NO: 6, as well as salts, functional derivatives, precursors and analogs thereof. The present invention also provides the peptides in substantially purified form, in order to be suitable for use in pharmaceutical compositions as active ingredient in pathologies that require IL-6 activity inhibition.

IL-6 antagonist peptides

The present invention relates to IL-6 antagonist peptides, isolatable from a peptide library through the two-hybrids system by their ability to bind to the intracellular domain of gp 130 and containing at least 5 amino acids. In particular, such peptides comprise an amino acid sequence, which is selected from the group consisting of: SEQ ID NO: 3, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7 SEQ ID NO: 8 as well as salts, functional derivatives, precursors and analogs thereof. Another object of the present invention is to provide the peptide in substantially purified form, in order to be suitable for use in pharmaceutical compositions as active ingredient in pathologies that require IL-6 activity inhibition.
