Use of IkappaB-kinase inhibitors in pain therapy

Description

FIELD OF THE INVENTION

[0002] The invention relates to the use of IκB-kinase inhibitors for treating pain.

BACKGROUND OF THE INVENTION

[0003] Patent applications WO 01/00610, WO 01/30774 and WO 01/68648, the content of each of which is incorporated herein by reference, describe compounds which are able to modulate NFκB. NFκB is a heterodimeric transcription factor which is able to activate a large number of genes which encode, inter alia, proinflammatory cytokines such as IL-1, IL-2, TNFα or IL-6. NFκB is present in the cytosol of cells, where it is complexed with its naturally occurring inhibitor IκB. Stimulation of the cells, for example by cytokines, leads to the IκB being phosphorylated and subsequently broken down proteolytically. This proteolytic breakdown leads to the activation of NFκB, which then migrates into the nucleus of the cell, where it activates a large number of proinflammatory genes.

[0004] In diseases such as rheumatoid arthritis (in connection with inflammation), osteoarthritis, asthma, cardiac infarction, Alzheimer's diseases or atherosclerosis, NFκB is activated to beyond the normal extent. The inhibition of NFκB is also of value in the treatment of cancer since it is used in such treatment to augment the cytostatic therapy. It has been demonstrated that pharmaceuticals such as glucocorticoids, salicylates or gold salts, which are used in the therapy of rheumatism, inhibit the NFκB-activating signal chain at various points or interfere directly with the transcription of the genes. The first step in said signal cascade is the breakdown of IκB. This phosphorylation is regulated by the specific IκB kinase.

[0005] Pharmaceuticals belonging to a large number of different substance groups are employed in treating acute and chronic pain. Despite this, the therapy of pain has still not been satisfactorily solved even today. This is due, in particular, to the fact that the analgesics which are on the market do not have a sufficiently powerful effect.

[0006] In an endeavor to obtain active compounds for treating pain, it has now been found that it is possible to use IκB-kinase inhibitors for this purpose. In particular, it has been possible to demonstrate, in the models employed, a strength of effect which is clearly superior to that of classical nonsteroidal anti-inflammatory agents.

[0007] The invention relates, therefore, to the use of IκB-kinase inhibitors for producing pharmaceuticals for treating pain.

[0008] The term “pain” is understood as meaning acute pains and chronic pains. The following are examples of chronic pains:

[0009] chronic musculoskeletal diseases, such as back pains,

[0010] pains associated with menstrual bleeding,

[0011] pains associated with osteoarthritis or rheumatoid arthritis,

[0012] pains associated with intestinal inflammation,

[0013] pains associated with cardiac muscle inflammation,

[0014] pains associated with multiple sclerosis,

[0015] pains associated with neuritis,

[0016] pains associated with carcinomas and sarcomas,

[0017] pains associated with AIDS,

[0018] pains associated with chemotherapy,

[0019] amputation pain,

[0020] trigeminus neuralgia,

[0021] headaches, such as migraine cephalalgia, or

[0022] neuropathic pains, such as post-herpes zoster neuralgia.

[0023] The following are examples of acute pains:

[0024] pains following injuries,

[0025] post-operative pains,

[0026] pains in association with an acute attack of gout, or

[0027] acute pains following jaw-bone surgery interventions.

[0028] Examples of IκB-kinase inhibitors are indole derivatives or benzimidazole derivatives as are described in the patent applications WO 01/00610 and WO 01/30774.

In particular, the heterocyclic ring is substituted at carbon atoms, once or more than once, for example once, twice, three times or four times, by identical or different radicals from the series —(C1-C8)-alkyl, for example —(C1-C4)-alkyl, —(C1-C8)-alkoxy, for example —(C1-C4)-alkoxy, such as methoxy, phenyl-(C1-C4)-alkoxy, for example benzyloxy, hydroxyl, oxo, halogen, nitro, amino or trifluoromethyl and/or is substituted at the ring nitrogen atom(s) in the heterocyclic ring by —(C1-C8)-alkyl, for example —(C1-C4)-alkyl such as methyl or ethyl, by optionally substituted phenyl or phenyl-(C1-C4)-alkyl, for example benzyl. Nitrogen heterocycles can also be present as N-oxides or as quaternary salts.

[0341] Examples of the terms heteroaryl having from 5 to 14 ring members and heterocycle having from 5 to 12 ring members are radicals which are derived from pyrrole, furan, thiophene, imidazole, pyrazole, oxazole, isoxazole, thiazole, isothiazole, tetrazole, 1,2,3,5-oxathiadiazole-2-oxides, triazolones, oxadiazolones, isoxazolone, oxadiazolidinedione, triazole, which are substituted by F, —CN, —CF3 or —C(O)—O—(C1-C4)-alkyl, 3-hydroxypyrro-2,4-diones, 5-oxo-1,2,4-thiadiazoles, pyridine, pyrazine, pyrimidine, indole, isoindole, indazole, phthalazine, quinoline, isoquinoline, quinoxaline, quinazoline, cinnoline, -carboline and benzo fused, cyclopenta fused, cyclohexa fused or cyclohepta fused derivatives of these heterocycles. Particular preference is given to the radicals 2- or 3-pyrrolyl, phenylpyrrolyl, such as 4- or 5-phenyl-2-pyrrolyl, 2-furyl, 2-thienyl, 4-imidazolyl, methylimidazolyl, for example 1-methyl-2-, -4- or -5-imidazolyl, 1,3-thiazol-2-yl, 2-pyridyl, 3-pyridyl, 4-pyridyl, 2-, 3- or 4-pyridyl-N-oxide, 2-pyrazinyl, 2-, 4- or 5-pyrimidinyl, 2-, 3- or 5-indolyl, substituted 2-indolyl, for example 1-methyl-, 5-methyl-, 5-methoxy-, 5-benzyloxy-, 5-chloro- or 4,5-dimethyl-2-indolyl, 1-benzyl-2- or -3-indolyl, 4,5,6,7-tetrahydro-2-indolyl, cyclohepta[b]-5-pyrrolyl, 2-, 3- or 4-quinolinyl, 1-, 3- or 4-isoquinolyl, 1-oxo-1,2-dihydro-3-isoquinolyl, 2-quinoxalinyl, 2-benzofuranyl, 2-benzothienyl, 2-benzoxazolyl or benzothiazolyl or dihydropyridinyl, pyrrolidinyl, for example 2- or 3-(N-methylpyrrolidinyl), piperazinyl, morpholinyl, thiomorpholinyl, tetrahydrothienyl and benzodioxolanyl.

DETAILED DESCRIPTION OF THE INVENTION

[0342] The general structural formula of α-amino acids is as follows:

[0343] The α-amino acids differ from each other in the radical R which, within the context of the present application, is designated the “characteristic radical” of an amino acid. When R9 denotes the characteristic radical of amino acid, use is preferably made of the characteristic radicals of the following naturally occurring α-amino acids: glycine, alanine, valine, leucine, isoleucine, phenylalanine, tyrosine, tryptophan, serine, threonine, cysteine, methionine, asparagine, glutamine, lysine, histidine, arginine, glutamic acid and aspartic acid. Particular preference is given to histidine, tryptophan, serine, threonine, cysteine, methionine, asparagine, glutamine, lysine, arginine, glutamic acid and aspartic acid. In addition, amino acids which do not occur naturally, such as 2-aminoadipic acid, 2-aminobutyric acid, 2-aminoisobutyric acid, 2,3-diaminopropionic acid, 2,4-diaminobutyric acid, 1,2,3,4-tetrahydroisoquinoline-1-carboxylic acid, 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid, 2-aminopimellic acid, phenylglycine, 3-(2-thienyl)alanine, 3-(3-thienyl)alanine, 2-(2-thienyl)glycine, 2-aminoheptanoic acid, pipecolic acid, hydroxylysine, sarcosine, N-methylisoleucine, 6-N-methyllysine, N-methylvaline, norvaline, norleucine, ornithine, alloisoleucine, allothreonine, allohydroxylysine, 4-hydroxyproline, 3-hydroxyproline, 3-(2-naphthyl)alanine, 3-(1-naphthylalanine), homophenylalanine, homocysteine, homocysteic acid, homotryptophan, cysteic acid, 3-(2-pyridyl)alanine, 3-(3-pyridyl)alanine, 3-(4-pyridyl)alanine, 2-amino-3-phenylaminopropionic acid, 2-amino-3-phenylaminoethylpropionic acid, phosphinothricin, 4-fluorophenylalanine, 3-fluorophenyl-alanine, 4-fluorophenylalanine, 3-fluorophenylalanine, 3-fluorophenylalanine, 2-fluorophenylalanine, 4-chlorophenylalanine, 4-nitrophenylalanine, 4-aminophenylalanine, cyclohexylalanine, citrulline, 5-fluorotryptophan, 5-methoxytryptophan, methionine sulfone, methionine sulfoxide or —NH—NR11—C(O)N(R11)2, which are also substituted, where appropriate, are also preferred characteristic radicals of amino acid which are employed as the radical R8. When amino acids which occur naturally, and also amino acids which do not occur naturally, possess a functional group such as amino, hydroxyl, carboxyl, mercapto, guanidyl, imidazolyl or indolyl, this group can also be protected.

[0344] The N-protecting groups which are customary in peptide chemistry, for example protecting groups of the urethane type, benzyloxycarbonyl (Z), t-butyloxycarbonyl (Boc), 9-fluorenyloxycarbonyl (Fmoc), allyloxycarbonyl (Aloc), or of the acid amide type, in particular formyl, acetyl or trifluoroacetyl, and also of the alkyl type, for example benzyl, are preferably used as suitable protecting groups for this purpose. When an imidazole radical is present in R8, the sulfonic acid derivative of the formula IV, which is employed for the sulfonamide formation, serves, for example, as the group for protecting the imidazole nitrogen, which group can be eliminated once again in the presence of bases such as sodium hydroxide.

[0345] The compounds of the formulae I, Ia and Ib are prepared as described in patent applications WO 01/00610 and WO 01/30774, the content of each of which is incorporated herein by reference. The starting compounds for the chemical reactions are known or can be readily prepared using methods known from the literature.

[0346] Embodiments

[0347] Due to the pharmacological properties, which are evident in the models employed, of the IκB-kinase inhibitors which are used in accordance with the invention, said inhibitors are suitable for being employed in all forms of pain, in particular in association with pains in which inflammatory processes play a role.

[0348] The pharmaceuticals according to the invention can be administered orally, by inhalation, rectally or transdermally or by means of subcutaneous, intraarticular, intraperitoneal or intravenous injection. Oral or intraarticular administration is preferred.

[0349] The invention also relates to a process for producing a pharmaceutical which comprises bringing at least one compound of the formulae I or Ia, together with a pharmaceutically suitable and physiologically tolerated excipient and, where appropriate, other suitable active compounds, additives or auxiliary substances, into a suitable form for administration.

[0350] Examples of suitable solid or galenic preparation forms are granules, powders, sugar-coated tablets, tablets, (micro)capsules, suppositories, syrups, juices, suspensions, emulsions, drops or injectable solutions, and also preparations with protracted active compound release, in the preparation of which customary auxiliary substances, such as carrier substances, disintegrants, binders, coating agents, swelling agents, glidants or lubricants, flavorings, sweeteners and solubilizers are used. Frequently employed auxiliary substances which may be mentioned are magnesium carbonate, titanium dioxide, lactose, mannitol and other sugars, talc, milk protein, gelatin, starch, cellulose and its derivatives, animal and vegetable oils, such as cod liver oil, sunflower oil, groundnut oil or sesame oil, polyethylene glycol and solvents, such as sterile water and monohydric or polyhydric alcohols, such as glycerol. The pharmaceutical preparations are preferably produced and administered in dosage units, with each unit containing as the active constituent a particular dose of the compound of the formula I according to the invention. In the case of solid dosage units, such as tablets, capsules, sugar-coated tablets or suppositories, this dose can be up to about 1000 mg, preferably from about 50 mg to 300 mg, and, in the case of injection solutions in ampoule form, up to about 300 mg, preferably from about 10 mg to 100 mg. Depending on the activity of the compound according to the formulae I or Ia, daily doses of from about 20 mg to 1000 mg of active compound, preferably of from about 100 mg to 500 mg, are indicated for treating an adult patient of about 70 kg in weight. However, higher or lower daily doses may also possibly be appropriate. The daily dose can be administered either by means of a once-only administration in the form of a single dosage unit, or of several smaller dosage units, or by means of the multiple administration of subdivided doses at predetermined intervals.

[0351] As a rule, mass-spectroscopic methods (FAB-MS, ESI-MS) are used for determining end products. Temperatures are given in degrees centigrade; RT denotes room temperature (from 22° C. to 26° C.). Abbreviations which are used are either explained or correspond to the customary conventions. The invention is explained in more detail below with the aid of examples.

[0389] Experimental

Pharmacological Examples

[0390] IκB-Kinase ELISA:

[0391] The activity of the IκB-kinase was determined using an ELISA which comprised a biotinylated substrate peptide, which contained the amino acid sequence in the IκB protein from serine 32 to 36, and a specific polyclonal or monoclonal antibody (e.g. from New England Biolabs, Beverly, Mass., USA, Cat.: 9240), which only bound to the phosphorylated form of the IκB peptide. This complex was immobilized on an antibody-binding (protein A-coated) plate and detected using a conjugate 30 composed of a biotin-binding protein and HRP (e.g. streptavidin-HRP). The activity was quantified with the aid of a standard curve constructed using substrate phosphopeptide.

[0392] Implementation:

[0393] In order to obtain the kinase complex, 10 ml of HeLa S3 cell extract S100 were diluted with 40 ml of 50 mM HEPES, pH 7.5, brought to 40% with respect to ammonium sulfate and incubated on ice for 30 minutes. The precipitated pellet was dissolved in 5 ml of SEC buffer (50 mM HEPES, pH 7.5, 1 mM DTT, 0.5 mM EDTA, 10 mM 2-glycerophosphate), centrifuged at 20 000 g for 15 minutes and filtered through a 0.22 μm filter. The sample was loaded onto a 320 ml Superose-6 FPLC column (Amersham Pharmacia Biotech AB, Uppsala, Sweden) which had been equilibrated with SEC buffer and which was operated at 4° C. with a flow rate of 2 ml/min. The fractions which were located at the migration time of the 670 kDa molecular weight standard were combined for the activation. Activation was achieved by means of a 45-minute incubation with 100 nM MEKK1Δ, 250 μM MgATP, 10 mM MgCl2, 5 mM dithiothreitol (DTT), 10 mM 2-glycerophosphate and 2.5 μM microcystin-LR at 37° C. The activated enzyme was stored at −80° C. The test substances (2 μl), which were dissolved in DMSO, were preincubated, at 25° C. for 30 minutes, with 43 μl of activated enzyme (diluted 1:25 in reaction buffer 50 mM HEPES, pH 7.5, 10 mM MgCl2, 5 mM DTT, 10 mM β-glycerophosphate, 2.5 μM microcystin-LR). 5 μl of substrate peptide (biotin-(CH2)6-DRHDSGLDSMKD-CONH2) (200 μM) were then added, after which the mixture was incubated for one hour and the reaction was stopped with 150 μl of 50 mM HEPES, pH 7.5, 0.1% BSA, 50 mM EDTA, antibody [1:200]. 100 μl of the stopped reaction mixture or of a standard phosphopeptide dilution series (biotin-(CH2)6-DRHDS[PO3]GLDSMKD-CONH2) were then transferred to a protein A plate (Pierce Chemical Co., Rockford, Ill., USA), after which the plate was incubated for 2 hours while being shaken. After 3 washing steps with PBS, 100 μl of 0.5 μg/ml streptavidin-HRP (horseradish peroxidase) (diluted in 50 mM HEPES/0.1% BSA) were added for 30 minutes. After 5 washing steps with PBS, 100 μL of TMB substrate (Kirkegaard & Perry Laboratories, Gaithersburg, Md., USA) were added and the color development was stopped by adding 100 μL of 0.18 M sulfuric acid. The absorption was measured at 450 nm. The standard curve was produced by linear regression corresponding to a 4-parameter dose-effect relationship. This standard curve was used to quantify the enzyme activity or its inhibition by the test substances.

[0395] The IC50 for N-((S)-1-carbamoyl-2-diphenylaminoethyl)-2-(2-methylaminopyrimidin-4-yl)-1H-benzimidazole-5-carboxamide was 0.045 μM.

[0398] 1st model: Zymosan-induced paw inflammation in the rat;

[0399] Parameter: paw withdrawal time or paw withdrawal threshold during thermal or mechanical stimulation of the hind paw.

[0400] 2nd model: Kaolin/carrageenan-induced knee joint inflammation in the rat;

[0401] Parameter: reaction of spinal neurons during pressure stimulation of the knee.

[0402] Model 1

[0403] Experimental implementation: in short-term anesthesia using isoflurane, 1 mg of Zymosan (as a suspension in 100 μl of PBS (phosphate-buffered salt solution)) was injected subcutaneously into the middle of the plantar side of one of the experimental animal's hind paws. After that, two different behavioral tests were used to quantitatively determine the development of a hyperalgesia.

[0404] a) Determining the paw withdrawal time during thermal stimulation (Hargreaves test).

[0405] The experimental animal was placed in a transparent plastic chamber having a glass floor. As soon as the experimental animal was no longer moving, following the reconnaissance phase (about 5 min), an infrared light source was positioned directly below the hind paw to be stimulated and switched on. The lamp emitted focused infrared light of increasing intensity, such that the skin temperature of the hind paw increased almost linearly. As soon as the animal withdrew the paw, the lamp switched itself off. The temperature of the paw at the time it is withdrawn has just become unpleasant for the animal; this is referred to as the thermal pain threshold.

[0406] b) Determining the paw withdrawal threshold during mechanical stimulation (von Frey test) The experimental animal was placed in a transparent plastic chamber whose floor consisted of wire-gauze. Punctate pressure of defined strength was produced using calibrated nylon fibers, what are termed von Frey hairs. The weakest pressure stimulation during which the animal withdrew its paw determines the mechanical pain threshold.

[0407] About half an hour before, and at various times after, the Zymosan injection, the thermal and mechanical pain thresholds were determined on the right hind paw and on the left hind paw (see Tables 1, 2). The decrease in the ipsilateral pain threshold, expressed in % of the contralateral pain threshold, was then calculated (see Tables 1, 2). The degree of hyperalgesia is directly proportional to the magnitude of this decrease.

[0408] In a control group, the Zymosan injection induced pronounced mechanical and thermal hyperalgesia (see control data in Tabs. 1 and 2). In another group of animals, which were under short-term isoflurane anesthesia, the abovementioned compound 13 was injected intraperitoneally (i.p.) (in each case 30 mg/kg in polyethylene glycol/water mixture (PEG/water 1:1) about 15 minutes before, and 2.5 and 5.5 hours after Zymosan injection. From two hours after Zymosan injection onward, the thermal hyperalgesia was less pronounced in these animals than it was in the control group; after the third administration of the substance, it was no longer possible to observe any side difference at all in the paw withdrawal time (Tab. 1). In addition, this effect still persisted for 18 hrs after the last administration of the substance.

[0409] Compound 13 also significantly reduced the mechanical hyperalgesia. The effect set in 1 hour after Zymosan injection and also still persisted 18 hrs after the last administration of the substance (see Tab. 2).

[0410] The activity of compound 13 is very strong in both test models. Comparative data from a study which was carried out previously show that compound 13 reduces the thermal hyperalgesia considerably more powerfully than does the NSAID diclofenac.

[0412] Model 2,

[0413] Experimental implementation: In rats which were under sodium thiopental anesthesia, the spinal canal was opened and spinal medullary neurons which processed the “pain impulses” from the knee-joint were identified. Following identification, a long-term recording, in which the activity of the nerve cell was recorded before and during the development of an acute inflammation in the knee-joint, was carried out. For this, the responses to non-noxious and noxious stimulation at the knee-joint were measured in a control period before inducing the inflammation and for several hours after inducing the inflammation.

[0414] The acute inflammation was induced by the intraarticular injection of a suspension (about 150 μl) of kaolin and carrageenan. In controlled experiments, only the vehicle was applied to the spinal medullary surface in order to represent the development of the hyperexcitability under control conditions. As a rule, this development of hyperexcitability took place within 2 to 4 hours and was expressed in a marked increase in the responses to non-noxious and noxious stimulation of the knee-joint (Tab. 3). In the experiments in which the abovementioned compound 13 was applied, the substance was added (about 30 μl of a 10 μM solution) to the spinal medulla about 30 minutes before inducing the inflammation. The responses of the cell to non-noxious and noxious stimulation were then subsequently monitored as in the control experiments.

[0415] Comparison of the changes in the responses in the two groups shows that, as compared with the controls, compound 13 almost completely suppressed the development of spinal hyperexcitability (Tab. 3). Taken overall, the effect of compound 13 on the responses to noxious knee-joint stimulation was more strongly expressed than was the effect of indomethacin, as was shown by a comparison with published data from an earlier study.

[0418] The data verify the good effect of compound 22 in model 2.

[0419] 3rd Model: Zymosan-Induced Paw Inflammation in the Mouse;

[0420] Parameter: paw withdrawal time during thermal stimulation of the hind paw. Experimental implementation: In short-term anesthesia using isoflurane, 25 μl of a suspension containing 50 mg of zymosan/ml were injected into the right hind paw of the experimental animal. The development of a hyperalgesia was then determined quantitatively as follows:

[0421] Determining the paw withdrawal time during thermal stimulation (Hargreave's test; see above).

[0422] The experimental animal was placed in a transparent plastic chamber having a glass floor. As soon as the experimental animal was no longer moving, following the reconnaissance phase (about 5 min), an infrared light source was positioned directly below the hind paw to be stimulated and switched on. The lamp emitted focused infrared light of increasing intensity such that the skin temperature of the hind paw increased almost linearly. As soon as the animal withdrew the paw, the lamp switched itself off. The temperature of the paw at the time it is withdrawn has just become unpleasant for the animal; this is referred to as the thermal pain threshold.

[0423] Shortly before the zymosan injection, and for from 7 to 14 days after the injection, the thermal pain threshold was determined once daily on the right hind paw and left hind paw. Subsequently, the integral of the area which was formed from the curves for the paw withdrawal times of the inflamed paw and the noninflamed paw (AUC, area between the curves, see tables 5 and 6) was determined as a measure of the hyperalgesia. The larger this value is, the more pronounced is the hyperalgesia, and the smaller the value is in animals which are being given the substance, the greater is the success of the therapy.

[0424] In a 7-day study, the zymosan injection induced pronounced thermal hyperalgesia in a control group (see vehicle, tab. 5). In the other groups, the substance was administered for the first time one day after the zymosan injection, after marked thermal hyperalgesia had already developed. Compound 13 was then administered orally twice daily for 7 days, in each case at the rate of 25 or 75 mg/kg in HEC/lipofundin (1% HEC in lipofundin). Analysis of the paw withdrawal times during the entire period of the study (7 days) showed that, when the substance was administered, the AUC decreased in a dose-dependent manner. At single doses of from 8.3 mg/kg and upwards, a significant therapeutic effect was achieved as compared with the vehicle group (tab. 5). Compound 13 exhibits very strong activity in the test model. A very high dose of paracetamol was likewise administered twice daily to another group of animals which was taken through the experiment in parallel. Compound 13 reduced the thermal hyperalgesia to a greater extent than did paracetamol (tab. 5).

[0425] In another study carried out on mice, the activity of compound 13 was compared with that of the specific COX-2 inhibitor Celecoxib. The scheme for zymosan injection and dosing was identical to that in the previously described study. The only difference was that this additional study ran for 14 days.

[0426] Once again, compound 13 was able to reduce thermal hyperalgesia in a dose-dependent manner (tab. 6). In the experiment, compound 13 and Celecoxib had equally strong effects at the high dosage (tab. 6).

[0427] 4th Model: Zymosan-Induced Paw Inflammation in the Mouse;

[0428] Parameter: spontaneous running performance in a running wheel. In the cage in which it is kept, the experimental animal has access to a running wheel, the revolutions of which are recorded electronically. During the night hours, the C57/B6 mice use the running wheel voluntarily and, after a one-week phase of acclimatization, cover on average 4 100 meters/night. After zymosan has been injected, the distance run each night is reduced. This reduction in running performance is a valid parameter for a restriction in function which is due to inflammation pain. Experimental implementation: After an acclimatization phase of one week, the distance run/24 hours was measured in order to determine the base line. 25 μl of a suspension containing 50 mg of zymosan/ml were then injected into the right hind paw of the experimental animal during short-term anesthesia using isoflurane. The distance run/24 hours was then determined during the following seven days. In the analysis, the area under the curve for the values for the distance run was determined (AUC, tab. 7): the lower the AUC, the lower was the running performance during the week following injection of the zymosan. Compound 13 was administered twice daily for 7 days, with the dose in each case being 25 or 75 mg/kg in HEC/lipofundin (1% HEC in lipofundin). The substance was administered for the first time on day 1 after injection of the zymosan.

[0429] In one study, the effect of compound 13 on running performance following zymosan injection was compared with that of paracetamol. A dose-dependent increase in the distance run, which was significant as compared with the vehicle group, was found in the case of both the higher doses (tab. 7). By contrast, no improvement as compared with the vehicle group was achieved when paracetamol was used at an extremely high dose (also 2 □ daily) (tab. 7).
