Definitions
- D-enantiomeric peptides for the anti-inflammatory treatment of amyotrophic lateral sclerosis (ALS) and other neuro-inflammatory diseases
- the present invention relates to a polymer, and to a pharmaceutical composition comprising such a polymer for use in the treatment of amyotrophic lateral sclerosis.
- ALS Amyotrophic lateral sclerosis
- ALS is a neurodegenerative disease of the motor nervous system characterized by progressive, irreversible motor neuron loss in middle age. With an incidence of 2 per 100,000, ALS is one of the rare diseases.
- the clinical picture of ALS is characterized by peripheral and central paresis caused by damage or degeneration of the first and second motor neurons. In the disease process, it usually comes after initial asymmetric paralysis of the extremities, speech and
- the object of the present invention is to overcome the above-mentioned disadvantages of the prior art.
- the object of the present invention is to provide a substance which is able to treat ALS causally or at least significantly slow the course of the disease.
- the present invention solves this by the use of a polymer according to claim 1, in particular by a polymer comprising at least one monomer, wherein the at least one monomer is a peptide having an amino acid sequence selected from the group consisting of SEQ ID NO: 1 ptlhthnrrrrr or Homologs having an identity of at least 80%, preferably amidated at the C-terminus, in the treatment of amyotrophic lateral sclerosis (ALS).
- ALS amyotrophic lateral sclerosis
- polymer encompasses all “multimers” which comprise at least two monomer units.
- polymers also includes, for example, dimers, trimers and oligomers.
- homologous sequences or “homologues” in the context of the invention means that an amino acid sequence has an identity with one of the abovementioned amino acid sequence of the monomers of at least 50, 55, 60, 65, 70, 71, 72, 73, 74, 75, 76 , 77, 78, 79,
- the identity between two nucleic acid sequences or polypeptide sequences is defined by the identity of the nucleic acid sequence / polypeptide sequence over the entire sequence length as determined by comparison with the aid of the GAP program based on the Needleman, SB and Wish, CD (J. Mol. Biol. 48: 443-453) is calculated by setting the following parameters for amino acids: gap creation penalty: 8 and gap extension penalty: 2; and the following parameters for nucleic acid gap creation penalty: 50 and gap extension penalty: 3.
- Two amino acid sequences are identical for the purposes of the present invention, if they have the same amino acid sequence.
- homologs also include the corresponding retro-inverse sequences of the abovementioned monomers.
- the polymer of the invention is further preferably characterized in that the at least one monomer is a peptide having an amino acid sequence selected from the group consisting of SEQ ID NO: 1 (RD2 monomer) ptlhthnrrrrrrr
- monomers also sequences are used which contain the above-mentioned sequences.
- the monomers have fragments of the abovementioned sequences.
- the polymer according to the invention is preferably characterized in that it contains 2,
- the polymer being particularly preferably comprises 2 monomers.
- the polymer of the invention is preferably further characterized by containing identical or non-identical monomers.
- the polymer according to the invention particularly preferably comprises a dimer of two peptides of SEQ ID NO 1 (RD2).
- the monomers are covalently linked to one another. In a further embodiment, the monomers are not covalently bound together.
- a covalent linkage of the monomer units is within the meaning of the invention, if the peptides are linearly linked head to head, tail to tail or head to tail.
- the monomers can be knotted together directly or via a linker group.
- a linker is to be understood as meaning one or more molecules which are bound to the monomers via covalent bonds, wherein these linkers may also be linked to one another by covalent bonds.
- a non-covalent linkage in the context of the invention is present if the monomers are linked together via biotin and streptavidin, in particular streptavidin tetramer.
- the monomers can be linearly linked together, in particular as described above.
- the monomers are branched together to form the polymer according to the invention.
- a branched polymer may be a dendrimer in which the monomers are covalently or noncovalently linked to one another or the monomers are linked to a platform molecule or are linked in a combination of these options.
- the polymer according to the invention is a polymer comprising two peptides of SEQ ID NO.1, which are covalently linked together, so that a peptide with the amino acid SEQ ID NO: 2 (RD2RD2) is formed.
- the polymer according to the invention consists of a peptide of SEQ ID NO. 2 (RD2RD2) ptlhth nrrrrrrptlhth nrrrrrr.
- polymer or peptide according to the invention essentially or completely consists of D-amino acids.
- the term "essentially of D-amino acids" means that the monomers to be used at least 60%, preferably 75%,
- polymers described above can be prepared, for example, by chemical synthesis or peptide synthesis.
- the polymer is linked to a further substance.
- the invention also relates in one embodiment to peptides according to the invention which are linked to another substance.
- the linkage is a chemical bond, as defined in Römpp Chemie Lexikon, 9th edition, Volume 1, page 650 et seq., Georg Thieme Verlag Stuttgart, preferably a valence bond, in particular a covalent bond ,
- the substances are drugs or active substances, defined in accordance with the Medicinal Products Act ⁇ 2 respectively. ⁇ 4 (19), as of September 2012.
- active substances are therapeutically active substances which are used as medicinally active substances.
- compounds are the solubility of the Peptides, the uptake of peptides in the gastrointestinal tract and / or improve the passage of the blood-brain barrier.
- prodrugs are of strategic importance, in particular, in those cases in which the active principle, e.g. the polymer according to the invention, if administered directly, would not or only slightly or not selectively enough reach the desired site of action.
- the prodrug concept is aimed primarily at improving pharmacokinetic properties of the substance.
- the use of prodrugs may improve oral absorption or bioavailability, reduce the first-pass effect, or enable a drug to pass the blood-brain barrier.
- the present invention further relates to a pharmaceutical composition comprising a polymer as defined above for use in the treatment of ALS.
- composition is preferably a polymer, as defined above, in a pharmaceutically effective concentration, as well as the usual additives, before.
- a pharmaceutically effective concentration as well as the usual additives, before.
- RD2RD2 The polymer according to the invention (RD2RD2) has SEQ ID NO: 2.
- the inven tion proper polymer consisted exclusively of D-amino acids.
