Definitions
- the present invention relates to C5a receptor antagonists and uses thereof.
- complement system In addition to the adaptive immune system, there is a system that is clearly older in terms of the ancestry to ward off infections.
- This system is called the complement system and consists of more than 30 soluble and membrane-bound proteins.
- the complement system can be activated together with the adaptive immune response or independently, e.g. to kill parhogenic bacteria. Excessive activation or insufficient regulation of the complement system is associated with a large number of inflammatory diseases, e.g. septic shock, reperfusion damage, rheumatoid arthritis, graft rejection, acute respiratory distress syndrome (ARDS), systemic lupus erythematosus (SLE) and gomeralonephritis.
- septic shock e.g. septic shock, reperfusion damage, rheumatoid arthritis, graft rejection, acute respiratory distress syndrome (ARDS), systemic lupus erythematosus (SLE) and gomeralonephritis.
- ARDS
- the complement system can be activated in three different ways. These are called classic, alternative and mannose-binding lectin (MBL) pathways. All paths run through the sequential processing - and thus activation - of inactive professions of proteases. Since the activated protease can activate the next proform, the triggering reaction is amplified comparable to the coagulation cascade.
- MBL mannose-binding lectin
- C3b is a key component of a central protease in the complement cascade, the C5 convertase.
- C3b is part of the C5 convertase of both the classic and the alternative route.
- the MLB route also leads via the convertases of the classic route.
- the C5 convertase is responsible for the progress of the complement cascade and catalyzes the cleavage of C5.
- C3b is covalently bound to the surface of, for example, bacteria, which can thereby preferably be taken up by macrophages. The same applies to the clarification of immune complexes.
- C3a is the small fragment that is formed alongside C3b by the cleavage of C3.
- C3a is a relatively weak chemokine and belongs to the anaphylatoxins.
- C5b is formed by splitting C5.
- the fission product is the starting point for the formation of the membrane attack complex (MAC).
- the MAC forms a pore through which the plasma membrane of bacteria as well as the body's own cells can be perforated. This can lead to lysis of the perforated cells.
- C5a is the 74 amino acid, N-terminal cleavage product of the ⁇ chain of the plasma protein C5 and is released by the activity of the C5 convertase.
- C5a is bound by its receptor, which is called C5aR or CD88, with high affinity and triggers a variety of pro-inflammatory effects. It is one of the strongest chemokines and, like C3a, belongs to the anaphylatoxins.
- the C5aR can be found on a variety of cells. The receptor is found particularly on damrophils, macrophages, smooth muscle cells and endothelial cells.
- C5a The release of C5a is directly or indirectly responsible for a variety of diseases. Examples include sepsis (Huber-Lang et al. 2001 Faseb Journal 15: 568-570), multiple sclerosis (Mullerladner et al. 1996 Journal of Neurological Science 144: 135- 141), reperfusion damage (Riley et al. 2000 Journal of Thoriacic and Cardiovascular Surgery 120: 350-358), psoriasis (Bergh et al. 1993 Archives of Dermatological Research 285: 131-134), rheumatoid arthritis (Woodruff et al.
- C5aR antagonist also referred to herein as a C5aR antagonist.
- small molecules include L-156602 (Merck), RPR120033 (Rhone-Poulenc), W-54011 (Mitsubishi Pharma) and NGD 2000-1 (Neurogen). All previously known inhibitors with a molecular weight of ⁇ 500 g mol have at least one of the following disadvantages: low specificity, agonistic activity, too low affinity, poor solubility, insufficient metabolic stability or inhibition of P450 enzymes.
- C5aR antagonists Another way to develop C5aR antagonists has been through the use of recombinant proteins.
- Examples of such protein-based antagonists are CGS 32359 (Ciba-Geigy, Pellas et al. 1998 Journal of Immunology 160: 5616-5621), ⁇ prfl-A8 (Heller et al. 1999 Journal of Immunology 163: 985-994) and Antibodies, which can be of recombinant or non-recombinant origin (Huber-Lang et al. 2001 Faseb Journal 15: 568-570).
- These C5aR antagonists are proteins and therefore expensive to manufacture. They are characterized by a relatively high affinity and specificity, but they have the disadvantage of a high immunogenicity. In addition, proteins can only be obtained using complex processes such as Administer injections efficiently.
- sequence information from the C-terminal region of C5a was used to develop peptide antagonists.
- Peptides as therapeutically usable antagonists of the C5aR have the advantage of lower production costs, no immunogenicity and high plasma stability compared to protein therapeutics and are also more specific than most of the previously known small molecules.
- Peptide antagomes have been described in large numbers. A common characteristic of almost all peptide C5aR antagonists is their origin in the C-terminus of C5a.
- peptide C5aR antagonists or partial agonists are described, inter alia, in the following patent applications or patents: US 4,692,511, US 5,663,148, WO 90/09162, WO 92/11858, WO 92/12168, WO 92/21361, WO 94 / 07518, WO 94/07815, WO 95/25957, WO 96/06629, WO 99/00406 and WO 99/13899, WO 03/033528.
- De Martino et al. (1995 Journal of Biological Chemistry 270: 15966-15969) a first structural attempt is made to explain the importance of C-terminal arginine in peptide C5aR ligands.
- WO 90/09162 presents 38 peptide inhibitors with their IC50 values (Examples 2, 13, 23, 31, 91, 106, 111, 117, 131, 150, 165, 182, 188, 202, 213, 220, 229 , 245, 247, 249, 279, 282, 295, 296, 305, 316, 338, 348, 377, 402, 404, 409, 421, 424, 432, 445, 455, 460).
- 37 peptides have a C-terminal arginine and only one peptide carries another C-terminal amino acid (tyrosine, example 305).
- sequence of example 305 from WO 90/09162 is Ac-, Phe-Lys-Ala-Cha-Ala-Leu-ala-Tyr-OH and an ido value for the binding of 0.17 ⁇ M is described, which is less corresponds to one tenth of the activity of other peptides described with a C-terminal arginine (for example Ac-Phe-Lys-Ala-Cha-Ala-Leu-N-Methyl (D) ala-Arg-OH (Example 296) and (N- Ethyl) Phe-Lys-Ala-Cha-Ala-Leu-N-Methyl (D) ala-Arg-OH (Example 402) with an IC 50 value of 0.012 ⁇ M or 0.011 ⁇ M).
- a C-terminal arginine for example Ac-Phe-Lys-Ala-Cha-Ala-Leu-N-Methyl (D) al
- this tyrosine-containing compound even shows only an IC 50 value of only 1.3 ⁇ M.
- Functional assay systems usually have a higher predictive value for activity in vivo than binding assays. This makes it clear that the use of a C-terminal tyrosine did not result in a compound that can be used to develop a therapeutically useful C5aR antagonist. This may also be the reason why the authors have not described any other tyrosine-containing peptides with a value for the activity.
- WO 92/12168 describes a further 20 peptides with their IC 50 values (binding to C5aR). 19 of these have a terminal arginine, which can exist in both the D and the L form. A peptide carries a phenylbutanoyl residue at the C-terminal, which could enter into a hydrophobic interaction.
- This peptide (Example 170) has the sequence (N-methyl) Phe-Lys-Pro-cha-Phe-Phenylbutanoyl and is given an ICs ⁇ value of only 2.6 ⁇ M, which does not appear to be promising for use as a medicament
- ICs ⁇ value of only 2.6 ⁇ M, which does not appear to be promising for use as a medicament
- a direct comparison between C-terminal argininyl and phenylbutanoyl is only partially possible in this application, since the directly comparable mechanism with a C-terminal arginine was not disclosed.
- Example 105 from WO 92/12168 ((N-methyl) Phe-Lys-Procha- ⁇ ⁇ CH 2 -N (CH 2 CH 2 C 6 H 5 ) ⁇ - Arg-OH) is most likely to be compared with Example 170 is suitable.
- the IC 50 value for this hexamer is 0.36 ⁇ M.
- the substitution of Arg leads to a significant decrease in activity in these examples as well.
- IC 50 values given in the international applications mentioned WO 90/09162, WO 92/12168 and WO 94/07518 were obtained by measurements with isolated membranes of polymorphic damrophil granulocytes (PMN membranes), since at the time the experiments were carried out there were no C5aR overexpressing cells could be produced.
- the resulting values do not reflect the affinity of the connection on whole cells.
- the connections to receptors on whole cells are significantly less affine (Kawai et al. 1991 Journal of Medicmical Chemistry 34: 2068-71; Rollins et al. 1988 Journal of Biological Chemistry 263: 520-526). However, it is more meaningful to measure their biological activity instead of the binding of the antagonists to the receptors.
- Such functional assays are often used for G protein coupled receptors.
- WO 99/00406 describes a series of cyclic and linear peptide inhibitors, the common feature of which is the C-terminal arginine.
- the necessary positive charge which is realized, for example, by arginine, is explicitly dealt with (WO 99/00406 page 12, line 13ff).
- C5a-desArg carboxypeptidases
- WO 03/033528 reports individual substitutions of different amino acids in the Ac-Phe [Orn-Pro-cha-Trp-Arg] molecule (compound 1). It is stated that, for example, the replacement of arginine in compound 1 by homoargimn (compound 44), CitruUin (compound 45), lysine (compound 47) or canavanine (compound 48) leads to a deterioration in the affinity for the C5a receptor and the antagonistic properties leads.
- WO 03/033528 does state that the arginine substitution from 1 (arginine) to 45 (citruUin) gives a compound that is said to have remarkable antagonistic activity (p. 44, lines 28ff.).
- the limit of what is classified as remarkable is arbitrary and the significant decrease in antagonistic activity by a factor of 24 underlines the importance of arginine at the C-terminal position of peptide C5aR antagonists known in the art.
- the peptide 45 containing citruUin is moreover the only peptide which does not carry a net positive charge under physiological conditions and for which a value for the binding and the antagonistic activity is described in WO 03/033528.
- the object of the present invention is to provide antagonists of the C5a receptor.
- a further object on which the present invention is based is to provide medicaments which can be used in the treatment of clinical pictures in which the C5a receptor is causally, indirectly or symptomatically involved.

- the treatment can be a treatment in the narrower sense, but also includes preventive treatment and follow-up treatment.
- CPB Cardiopuhnunary Bypass
- the patient to be treated is preferably a mammal, more preferably farm animals, sports and pets, and most preferably humans.
- the patient is one who needs treatment.
- the patient suffers from one of the above diseases, for the treatment and / or prevention of which the compounds according to the invention can be used.
- the present invention thus provides for the first time those antagonists of the C5a receptor which overcome the inherent pharmacological disadvantages of the prior art antagonistically active peptides provided with a positive charge.
- the present invention is based on the surprising finding that, in contrast to the teaching of the prior art, antagonists of the C5a receptor can also be obtained which do not carry a positive net charge under physiological conditions, in particular at a pH of 7.4 and / or whose C-terminal amino acid has no positive charge under physiological conditions.
- the positive charge in peptides can be very disadvantageous from a pharmacological point of view. So positive charges e.g. lead to histamine release and cause less membrane passage (cf. Example 15). It is therefore particularly desirable to develop a peptide antagonist that does not have a net positive charge (hereinafter also referred to as a compound).
- Avoiding a C-terminal positive charge can also have other positive effects.
- Receptor specificity or parameters that are important in vivo such as pharmacokinetics, plasma protein binding or mutagenicity, can be positively influenced.
- the compounds mentioned in the present invention were tested in a primary test for their IC 50 values in a functional test system.
- all compounds, peptides and peptidomimetics are regarded as within the meaning of the present invention have noteworthy inhibitory activity, which has an IC 5 o value in a functional assay system as described in Example 1, point of less than 200 nM.
- the compounds according to the invention are antagonists of the C5a receptor. Even more preferably, these are designed as peptides or peptidomimetics. Furthermore, the present invention is based on the surprising finding that the compounds to be used according to the invention as antagonists of the C5a receptor carry an uncharged C-terminal amino acid, amino acid derivative or amino acid analogue.
- Particularly preferred compounds and antagonists according to the present invention are the following cyclic compounds.
- linear, that is to say structurally flexible, peptides can be potent inhibitors as well as structurally fixed cyclic peptides. This may be due to the substitution of the C-terminally charged arginine by hydrophobic amino acids, amino acid derivatives or amino acid analogs.
- linear peptide inhibitors according to the invention are in particular the compounds listed in the following table:
- linear peptides are generally significantly worse antagonists of C5a than cyclic peptides, such as those described in WO 99/00406 (for example Ac-Phe- [Lys-Pro-cha -T ⁇ -arg], Ac-Phe- [Orn-Pro-cha-T ⁇ -arg], Ac-Phe- [Orn-Pro-cha-T ⁇ -Arg], Ac-Phe- [Lys-Pro-cha-T ⁇ Arg]).
- the most active linear peptide described in WO 99/00406 has the sequence Me-Phe-Lys-Pro-cha-T ⁇ -arg and shows an IC 50 value of 0.085 ⁇ M (measured using the cellular myeloperoxidase release assay) human PMNs).
- the comparable cyclic peptide Ac-Phe- [Lys-Pro-cha-T ⁇ -arg] shows an IC 5 o-value of 0.012 uM. ha WO 99/00406 states that less structural flexibility of the cyclic peptide leads to a reduction, ie improvement, in the IC 50 value.
- the present invention thus describes for the first time peptidic or peptidomimetic C5aR antagonists with inhibitory activities with an IC 50 ⁇ 200 nM which do not carry a positive net charge under physiological pH values (pH 7.4) and / or whose C-terminal amino acid carries no positive charge ,
- the IC value is determined using a functional test (Kohl 1997 The Anaphylatoxins. In: Dodds, AW, Sim, RB (Eds.), Complement: A Practical Approach. Oxford, pp. 135-163).
- the compounds according to the invention can thus be used as C5aR antagonists, in particular also under physiological conditions.
- Another characteristic of the compounds according to the invention is the lack of agonistic activity in a cellular assay up to a concentration of at least 1430 nM.
- Example 12 shows an example of the results of measurements of a selection of the peptides according to the invention by means of a method with which the agonism with respect to the C5aR is determined. It is obvious that the compounds of the invention up to? show no agonistic activity at the maximum concentration used.
- HOCH 2 (CHOH) -C NO-CH 2 -CO-Phe- [Orn-Pro-cha- T ⁇ -Nle], Ph-CH 2 -CH 2 -CO- [Orn-Pro-cha-T ⁇ -Nle], Ac-Phe- [Orn-Hyp-cha-T ⁇ -Phe], H-Phe- [Orn-Pro-cha-T ⁇ -Phe], Ac-Phe- [Orn-Pro-cha-T ⁇ -Phe], Ac-Lys-Phe- [Orn-Pro-cha-T ⁇ -Nle], H-Phe- [Orn-Pro-cha-T ⁇ -Nle], H-Phe- [Orn-Ser-cha-T ⁇ -Nle], Ac-Phe- [Orn-Pro-cha-T ⁇ -Eafj, Ac-Phe-Orn-Pro-cha-T ⁇ -P
- the following peptides in particular are notably inhibitory: Ac-Phe- [Orn-Pro-cha-T ⁇ -Phe], Ac-Phe- [Orn-Hyp-cha-T ⁇ -Phe], Ac-Phe- [Orn-Pro-cha -T ⁇ -PafJ, Ac-Phe- [Orn-Pro-cha-T ⁇ -Ecr], Ac-Phe- [Orn-Pro-cha-T ⁇ -Ppa], Ac-Phe- [Orn-Pro-cha-T ⁇ - Nle], Ac- Phe- [Orn-Pro-cha-T ⁇ -Met], Ac-Phe- [Orn-Pro-cha-T ⁇ -Nva], Ac-Phe- [Orn-Pro-cha-T ⁇ -HIe] , Ac-Phe- [Orn-Pro-cha-T ⁇ -Eafj, Ac-Phe- [Orn-Pro-cha-T ⁇ -Ebd], Ac-Phe- [Orn-Pro-cha-T ⁇ -Eag],
- the oral intake of peptides is influenced by various factors such as size, charge and hydrophobicity.
- Peptides are generally considered to be poorly available orally (Burton et al. 1996 Journal of Pharmaceutical Sciences 85: 1337-1340).
- a model to estimate oral Abso ⁇ tion represents the measurement of the AB permeability through a monolayer layer of intestinal epithelial cells (eg CaCo2 or TC-7) (Example 15, Lennernäs 1997 Journal of Pharmacy and Pharmacology 49: 627-38).
- the compounds according to the invention which can be used as C5aR antagonists, have a significantly improved AB permeability due to the hydrophobic substitution of the C-terminal arginine.
- the antagonist Ac-Phe- [Orn-Hyp-cha-T ⁇ -Phe] shows a surprisingly good permeability of 14.3xl0 "6 cm / s compared to the poor permeability of 0.52xl0 " 6 cm / s of the charged antagonist Ac-Phe- [Orn-Pro-cha-T ⁇ -Arg].
- the high permeability is numerically in a range that is close to the substances that are readily available for oral use.
- An example of an orally very readily available compound is propanolol, which in this Lennernäs test shows an AB permeability of 31.1 10 "6 cm / s.
- the compounds according to the invention are those which are designed in such a way that groups which improve water solubility are additionally added to them at XI and / or X4.
- groups which have strong interactions with water and are strongly solvated is particularly favorable for improving water solubility. Commonly used examples are: hydroxy, keto, carboxamido, efher, urea, carbamate, amino, substituted amino, guanidino, pyridyl, carboxyl.
- the groups described can be expressly introduced at all positions of XI and / or X4 and both one and more of the groups which improve water solubility can be inserted. Examples of the introduction of several groups are the linking of carbohydrate tests or ethylene glycols.
- the present invention therefore also includes peptic or peptidomimetic C5aR antagonists, in particular according to the present invention, the solubility of which has been improved by additional modifications.
- modifications are known to the person skilled in the art and include, for example, the introduction of the abovementioned groups which improve water solubility. The following examples demonstrate that this is an effective measure or leads to highly effective antagonists.

- Example 28 Effectiveness of compound 149 in a model of immune complex mediated peritonitis
- the peritonitis mediated by the immune complex is part of the pathological occurrence in connection with diseases mediated by the immune complex, e.g. Vasculitis, nephritis, arthritis or farmer's lung.
- diseases mediated by the immune complex e.g. Vasculitis, nephritis, arthritis or farmer's lung.
- the corresponding model was developed by Heller et al. (1999 Journal of Immunology 163: 985-994) and is based on the proinflammatory effect of brain complex formation from i.v. given antigen and i.p. given Antikö ⁇ er.
- BALB / c mice (6-8 weeks old) were given iv with compound 149 according to the invention (1 mg / kg body weight in 200 ⁇ l vehicle) 15 min before the initiation of the reverse passive arthus Response treated.
- the Arthus reaction was triggered by the application of OSA (20 mg / kg iv in 200 ⁇ l PBS) and polyclonal anti-OVA Ab (rabbit; 800 ⁇ g / mouse ip). After 6 hours a peritoeneal lavage was carried out with 2 ml PBS 0.1% BSA.
- the PE cells obtained were stained using DIFF-Quick. At least 20 visual fields (100x magnification) were microscopically analyzed for the presence of granulocytes.
- C5a-induced neutropenia is a model for shock-like diseases (septic shock) in which, among other things, the systemic effects of C5a such as A drop in blood pressure and neutropenia plays an important role.
- the attachment of the neuttophils to the vessel wall, triggered by C5a, is the reason for the decrease in the number of neutrophils in the circulating blood (neutropenia). This process of recruiting neuttophils also plays a crucial role in many other diseases such as reperfusion damage.
- the model has been also by Short et al. (1999 British Journal of Pharmacology 125: 551-554).
- mice Female Wistar rats are i.p. anesthetized with ketamine (80 mg / kg) and xylazine (12 mg / kg). The rats are inhibited and a catheter is inserted into the jugular vein and the following treatment follows:
- the rats are pretreated with vehicle or compound 149 according to the invention by means of i.v. Infusion. A blood sample is taken one minute beforehand.
- the rats are treated with 2 ⁇ g kg hrC5a iv (2 ⁇ g / kg, 1 min). Blood samples are taken shortly before and at various times after HRC5a administration.
- Blood samples (approx. 0.2 ml) are taken from the jugular vein in lithium-heparin tubes. Differential blood images are obtained from the blood samples.
- White blood cells are determined with a hematology cell counter.
- Blood smears are made from the heparimized blood samples. Each sample is dehydrated with methanol before staining. After fixation, each slide is incubated with May Grünwald stain for 5 min. Then the slides are washed with aqua dest. rinsed. It is then stained with Giemsa stain for 2 min and the slides are washed once more in distilled water.
- the differential time number is determined as the sum of neuttophils, eosinophils, easophils, lymphocytes and monocytes from 100 cells. Then the percentage of neutrophils in the number of all white blood cells is determined.
- FIG. 2 shows that the administration of compound 149 significantly reduces the C5a-induced neutropenia and thus has the desired anti-inflammatory effect in this inflammation model.
- CitruUin although uncharged under physiological conditions, is nevertheless polar, albeit less polar than a charged guanidine. This is e.g. through the calculated logP values of various amino acid derivatives, as shown in the following overview:
- the logP value indicates the distribution ratio of a connection between a water and an octanol phase and is lower the polar the connection is.
- the logP values were predicted using the Cherndraw program (available from CambridgeSoft, Cambridge, Great Britain).
