Definitions
- New TNF peptides Description The invention relates to new peptides derived from tumor necrosis factor (TNF), their production and their use as medicaments.
- TNF tumor necrosis factor
- TNF is one of the main participants in inflammatory reactions (Pharmac. Res. 5, 129, 1988). in the Animal models showed the involvement of TNF in septic shock (Science 229, 869, 1985) and graft versus host disease (J. Exp. Med. 166, 1280, 1987). It has now been found that peptides with a significantly lower molecular weight have favorable properties.
- the invention relates to peptides of the formula I, X-A-Y I,
- Y for a group -Z, -NH-CHQ-CO-Z, -V-NH-CHQ-CO-Z, -NH-CHQ-CO-U-Z or
- G represents a hydrogen atom or an amino protecting group
- Z represents an OH or NH2 group or a carboxyl protecting group
- M and Q are hydrogen atoms or one of the groups
- M and Q together form a - (CH 2 ) c -SS- (CH 2 ) d -, - (CH 2 ) e -CO-NH- (CH 2 ) f - or - (CH 2 ) e -NH-CO- (CH 2 ) g -NH-CO- (CH 2 ) f bridge (with c and d meaning a number from 1 to 4, e and f a number from 1 to 6 and g a number from 1 to 12) mean, and their salts with physiologically acceptable acids.
- the peptides of formula I are made up of L-amino acids, but they can contain 1 to 2 D-amino acids.
- the side chains of the trifunctional amino acids can carry protective groups or be unprotected.
- Methanesulfonic acid acetic acid, formic acid, maleic acid, fumaric acid, malic acid, succinic acid, malonic acid, sulfuric acid, L-glutamic acid, L-aspartic acid, pyruvic acid, mucic acid, benzoic acid,
- Glucuronic acid oxalic acid, ascorbic acid, acetylglycine.
- the new compounds can be prepared by methods known in peptide chemistry.
- the fragments in turn being able to be obtained by sequential construction from amino acids or in turn by fragment coupling.
- the cyclic peptides are obtained by a cyclization reaction carried out in high dilution. Both in the sequential structure and in the fragment coupling, the building blocks must be linked by forming an amide bond. Enzymatic and chemical methods are suitable for this.
- the coupling reagents can be used alone or in combination with additives such as N, N'-dimethyl-4-aminopyridine (DMAP), N-hydroxybenzotriazole (HOBt), N-hydroxybenzotriazine (HOOBt), N-hydroxysuccinimide (HOSu) or 2-hydroxypyri.din be used.
- DMAP N, N'-dimethyl-4-aminopyridine
- HOBt N-hydroxybenzotriazole
- HOOBt N-hydroxybenzotriazine
- HSu N-hydroxysuccinimide
- 2-hydroxypyri.din 2-hydroxypyri.din be used.
- protective groups can be dispensed with, chemical synthesis requires reversible protection of the reactive functional groups of the two reactants which are not involved in the formation of the amide bond.
- three protecting group techniques known from the literature are preferred: the benzyloxycarbonyl (Z), the t-butyloxycarbonyl (Boc) and the 9-fluorenylmethyloxycarbonyl (Fmoc) protective group technique.
- the protective group of the ⁇ -amino function of the chain-extending building block is designated in each case.
- the side chain protecting groups of the trifunctional amino acids are chosen so that they are not necessarily split off together with the ⁇ -amino protecting group.
- the peptide is typically built up sequentially on the polymeric support using the Boc or Fmoc protective group technique, the growing peptide chain at the C-terminus being covalently linked to the insoluble resin particles (see Figs. 1 and 2). This procedure allows reagents and by-products to be removed by filtration, which means that the recrystallization of intermediate products becomes superfluous.
- the protected amino acids can be bound to any suitable polymers which are only insoluble in the solvents used and must have a stable physical form which enables easy filtration.
- the polymer must contain a functional group to which the first protected amino acid can be bound by a covalent bond.
- a wide variety of polymers are suitable for this purpose, e.g.
- All solvents which prove inert under the reaction conditions are suitable for peptide synthesis in solution, in particular water, N, N'-dimethylformamide (DMF), dimethyl sulfoxide (DMSO), acetonitrile, dichloromethane (DCM), 1,4-dioxane, Tetrahydrofuran (THF), N-methyl-2-pyrrolidone (NMP) and mixtures of the solvents mentioned.
- the peptide synthesis on the polymeric support can be carried out in all inert organic solvents in which the amino acid derivatives used are soluble; however, solvents which additionally have resin-swelling properties, such as DMF, DCM, NMP, acetonitrile and DMSO, and mixtures of these solvents are preferred.
- the new peptides show good cytotoxic properties. Another part of the peptides has a high affinity for the cellular TNF receptor without, however, having any cytotoxic activity. They therefore represent TNF antagonists. In competition with natural TNF, they bind to the cellular TNF receptor and thus suppress the TNF effect.
- the new peptides prove to be valuable medicinal products that are used for
- neoplastic diseases and autoimmune diseases Treatment of neoplastic diseases and autoimmune diseases as well as for the control and prophylaxis of infections, inflammation and
- Rejection reactions can be used in transplants. Simple experiments can be used to determine the mode of action of the individual peptides.
- Simple experiments can be used to determine the mode of action of the individual peptides.

In addition, some cell controls (ie, cell cultures not treated with peptide solution and not with rhu-TNF solution) and some
