Description
BACKGROUND OF THE INVENTION

The invention relates to antibacterial amide macrocycles and methods for their preparation, their use for the treatment and/or prophylaxis of diseases, as well their use for the production of medicaments for the treatment and/or prophylaxis of diseases, in particular of bacterial infections.


WO 03/106480 and WO 04/012816 describe macrocycles of the biphenomycin B type which have antibacterial activity and have amide and ester substituents respectively.

The natural products in terms of their properties do not comply with the requirements for antibacterial medicaments. Although structurally different agents with antibacterial activity are available on the market, the development of resistance is a regular possibility. Novel agents for a good and more effective therapy are therefore desirable.


SUMMARY OF THE INVENTION

One object of the present invention is therefore to provide novel and alternative compounds with the same or improved antibacterial activity for the treatment of bacterial diseases in humans and animals.


It has surprisingly been found that certain derivatives of these natural products in which the carboxy group of the natural product is replaced by an amide group which comprises a basic group have antibacterial activity against biphenomycin-resistant S. aureus Strains (RN4220BiR and T17).


In addition, the derivatives show an improved spontaneous resistance rate for S. aureus wild-type strains and biphenomycin-resistant S. aureus Strains.

The present invention further relates to a method for the treatment and/or prophylaxis of diseases, especially of the aforementioned diseases, using an antibacterially effective amount of the compounds of the invention.


The compounds of the invention may act systemically and/or locally. For this purpose, they can be administered in a suitable way such as, for example, orally, parenterally, pulmonarily, nasally, sublingually, lingually, buccally, rectally, dermally, transdermally, conjuctivally or otically or as an implant or stent.


For these administration routes the compounds of the invention can be administered in suitable administration forms.


Suitable for oral administration are administration forms which function according to the prior art and deliver the compounds of the invention rapidly and/or in modified fashion, and which contain the compounds of the invention in crystalline and/or amorphized and/or dissolved form, such as, for example, tablets (uncoated or coated tablets, for example having coatings which are resistant to gastric juice or dissolve with a delay or are insoluble and control the release of the compound of the invention), tablets or films/wafers, which disintegrate rapidly in the oral cavity, films/lyophilisates, capsules (for example hard or soft gelatin capsules), sugar-coated tablets, granules, pellets, powders, emulsions, suspensions, aerosols or solutions.


Parenteral administration can take place with avoidance of an absorption step (e.g. intravenous, intraarterial, intracardiac, intraspinal or intralumbar) or with inclusion of an absorption (e.g. intramuscular, subcutaneous, intracutaneous, percutaneous or intraperitoneal). Administration forms suitable for parenteral administration are, inter alia, preparations for injection and infusion in the form of solutions, suspensions, emulsions, lyophilisates or sterile powders.


Suitable for the other administration routes are, for example, pharmaceutical forms for inhalation (inter alia powder inhalers, nebulizers), nasal drops, solutions, sprays; tablets, films/wafers or capsules for lingual, sublingual or buccal administration, suppositories, preparations for the ears or eyes, vaginal capsules, aqueous suspensions (lotions, shaking mixtures), lipophilic suspensions, ointments, creams, transdermal therapeutic systems (such as, for example, patches), milk, pastes, foams, dusting powders, implants or stents.

This can take place in a manner known per se by mixing with inert, nontoxic, pharmaceutically suitable excipients. These excipients include, inter alia, carriers (for example microcrystalline cellulose, lactose, mannitol), solvents (e.g. liquid polyethylene glycols), emulsifiers and dispersants or wetting agents (for example sodium dodecyl sulfate, polyoxysorbitan oleate), binders (for example polyvinylpyrrolidone), synthetic and natural polymers (for example albumin), stabilizers (e.g. antioxidants such as, for example, ascorbic acid), colors (e.g. inorganic pigments such as, for example, iron oxides) and taste and/or odor corrigents.


The present invention further relates to medicaments which comprise at least one compound of the invention, usually together with one or more inert, nontoxic, pharmaceutically suitable excipients, and to the use thereof for the aforementioned purposes.


It has generally proved advantageous on parenteral administration to administer amounts of about 5 to 250 mg/kg of body weight per 24 h to achieve effective results. The amount on oral administration is about 5 to 100 mg/kg of body weight per 24 h.


It may nevertheless be necessary where appropriate to deviate from the stated amounts, in particular as a function of the body weight, administration route, individual behavior towards the active ingredient, nature of the preparation and time or interval over which administration takes place. Thus, it may be sufficient in some cases to make do with less than the aforementioned minimum amount, whereas in other cases the stated upper limit must be exceeded. Where larger amounts are administered, it may be advisable to divide these into a plurality of single doses over the day.


The percentage data in the following tests and examples are percentages by weight unless otherwise indicated; parts are parts by weight. Solvent ratios, dilution ratios and concentration data for liquid/liquid solutions are in each case based on volume.

In Vitro Transcription-Translation with E. Coli Extracts


In order to prepare an S30 extract logarithmically growing Escherichia coli MRE 600 (M. Müller; Freiburg University) are harvested, washed and employed it as described for the in vitro transcription-translation test (Müller, M. and Blobel, G. Proc Natl Acad Sci USA (1984) 81, pp. 7421-7425).


1 μl of cAMP (11.25 mg/ml) are additionally added per 50 μl of reaction mix to the reaction mix of the in vitro transcription-translation tests. The test mixture amounts to 105 μl, with 5 μl of the substance to be tested being provided in 5% DMSO. 1 μg/100 μl of mixture of the plasmid pBESTLuc (Promega, Germany) are used as transcription template. After incubation at 30° C. for 60 min, 50 μl of luciferin solution (20 mM tricine, 2.67 mM MgSO4, 0.1 mM EDTA, 33.3 mM DTT pH 7.8, 270 μM CoA, 470 μM luciferin, 530 μM ATP) are added, and the resulting bioluminescence is measured in a luminometer for 1 minute. The concentration of an inhibitor which leads to a 50% inhibition of the translation of firefly luciferase is reported as the IC50.


In Vitro Transcription-Translation with S. aureus Extracts


Construction of an S. aureus Luciferase Reporter Plasmid


For the construction of a reporter plasmid which can be used in an in vitro transcription-translation assay from S. aureus the plasmid pBESTluc (Promega Corporation, USA) is used. The E. coli tac promoter present in this plasmid in front of the firefly luciferase is replaced by the capA1 promoter with corresponding Shine-Dalgarno sequence from S. aureus. The primers CAPFor 5′-CGGCCAAGCTTACTCGGATCCAGAGTTTGCAAAATATACAG-GGGATTATATATAATGGAAAACAAGAAAGGAAAATAGGAGGTTTATATGGAAGAC GCCA-3′ and CAPRev 5′-GTCATCGTCGGGAAGACCTG-3′ are used for this. The primer CAPFor contains the capA1 promoter, the ribosome binding site and the 5′ region of the luciferase gene. After PCR using pBESTluc as template it is possible to isolate a PCR product which contains the firefly luciferase gene with the fused capA1 promoter. This is, after restriction with ClaI and HindIII, ligated into the vector pBESTluc which has likewise been digested with ClaI and HindIII. The resulting plasmid pla can be replicated in E. coli and be used as template in the S. aureus in vitro transcription-translation test.


Preparation of S30 Extracts from S. aureus


Six litres of BHI medium are inoculated with a 250 ml overnight culture of an S. aureus Strain and allowed to grow at 37° C. until the OD600 nm is 2-4. The cells are harvested by centrifugation and washed in 500 ml of cold buffer A (10 mM Tris acetate, pH 8.0, 14 mM magnesium acetate, 1 mM DTT, 1 M KCl). After renewed centrifugation, the cells are washed in 250 ml of cold buffer A with 50 mM KCl, and the resulting pellets are frozen at −20° C. for 60 min. The pellets are thawed on ice in 30 to 60 min and taken up to a total volume of 99 ml in buffer B (10 mM Tris acetate, pH 8.0, 20 mM magnesium acetate, 1 mM DTT, 50 mM KCl). 1.5 ml portions of lysostaphin (0.8 mg/ml) in buffer B are provided in 3 precooled centrifuge cups and each mixed with 33 ml of the cell suspension. The samples are incubated at 37° C., shaking occasionally, for 45 to 60 min, before 150 μl of a 0.5 M DTT solution are added. The lysed cells are centrifuged at 30 000×g and 4° C. for 30 min. The cell pellet is taken up in buffer B and then centrifuged again under the same conditions, and the collected supernatants are combined. The supernatants are centrifuged again under the same conditions, and 0.25 volumes of buffer C (670 mM Tris acetate, pH 8.0, 20 mM magnesium acetate, 7 mM Na3 phosphoenolpyruvate, 7 mM DTT, 5.5 mM ATP, 70 μM amino acids (complete from Promega), 75 μg of pyruvate kinase (Sigma, Germany)/ml are added to the upper ⅔ of the supernatant. The samples are incubated at 37° C. for 30 min. The supernatants are dialysed against 2 l of dialysis buffer (10 mM Tris acetate, pH 8.0, 14 mM magnesium acetate, 1 mM DTT, 60 mM potassium acetate) in a dialysis tube with a 3500 Da cut-off with one buffer change at 4° C. overnight. The dialysate is concentrated to a protein concentration of about 10 mg/ml by


covering the dialysis tube with cold PEG 8000 powder (Sigma, Germany) at 4° C. The S30 extracts can be stored in aliquots at −70° C.


Determination of the IC50 in the S. aureus In Vitro Transcription-Translation Assay


The inhibition of protein biosynthesis of the compounds can be shown in an in vitro transcription-translation assay. The assay is based on the cell-free transcription and translation of firefly luciferase using the reporter plasmid pla as template and cell-free S30 extracts obtained from S. aureus. The activity of the resulting luciferase can be detected by luminescence measurement.


The amount of S30 extract or plasmid pla to be employed must be tested anew for each preparation in order to ensure an optimal concentration in the test. 3 l of the substance to be tested, dissolved in 5% DMSO, are introduced into an MTP. Then 101 of a suitably concentrated plasmid solution pla are added. Then 46 μl of a mixture of 23 g of premix (500 mM potassium acetate, 87.5 mM Tris acetate, pH 8.0, 67.5 mM ammonium acetate, 5 mM DTT, 50 μg of folic acid/ml, 87.5 mg of PEG 8000/ml, 5 mM ATP, 1.25 mM of each NTP, 20 μM of each amino acid, 50 mM PEP (Na3 Salt), 2.5 mM cAMP, 250 μg of each E. coli tRNA/ml) and 23 g of a suitable amount of S. aureus S30 extract are added and mixed. After incubation at 30° C. for 60 min, 501 of luciferin solution (20 mM tricine, 2.67 mM MgSO4, 0.1 mM EDTA, 33.3 mM DTT pH 7.8, 270 μM CoA, 470 μM luciferin, 530 μM ATP) are, and the resulting bioluminescence is measured in a luminometer for 1 min. The concentration of an inhibitor which leads to a 50% inhibition of the translation of firefly luciferase is reported as the IC50.


Determination of the Minimum Inhibitory Concentration (CLSI Standard)

The minimum inhibitory concentration (MIC) is the minimum concentration of an antibiotic with which the growth of a test microbe is inhibited over 18-24 h. The inhibitor concentration can in these cases be determined by standard microbiological methods (see, for example, The National Committee for Clinical Laboratory Standards. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically; approved standard-fifth edition. NCCLS document M7-A5 [ISBN 1-56238-394-9]. NCCLS, 940 West Valley Road, Suite 1400, Wayne, Pa. 19087-1898 USA, 2000). The test substances are thereby initially provided in 1:2 dilution series into 96-well round-bottom microtiter plates (Greiner) double-concentrated in 50 μl of test medium. The aerobically growing test microbes (e.g. staphylococci and enterococci), which are incubated overnight on Columbia blood agar plates (Becton-Dickinson), are, after resuspension in 0.9% NaCl, adjusted to a microbe count of about 5×107 microbes/ml and then diluted 1:150 in cation-adjusted MH medium (test medium). 50 μL of this suspension are pipetted onto the test preparations provided in the microtiter plates. The cultures are incubated at 37° C. for 18-24 hours. For microaerophilically growing microbes (e.g. streptococci), 2% lysed horse blood in the final concentration is added to the medium and the cultures are incubated in the presence of 5% CO2. The lowest substance concentration in each case at which no visible bacterial growth occurs any longer is defined as the MIC and is reported in μg/ml.

NCCLS, 940 West Valley Road, Suite 1400, Wayne, Pa. 19087-1898 USA, 2000). The MIC of the compounds of the invention is determined in the liquid dilution test on the 96-well microtiter plate scale. The bacterial microbes are cultivated in a minimal medium (18.5 mM Na2HPO4, 5.7 mM KH2PO4, 9.3 mM NH4Cl, 2.8 mM MgSO4, 17.1 mM NaCl, 0.033 μg/ml thiamine hydrochloride, 1.2 μg/ml nicotinic acid, 0.003 μg/ml biotin, 1% glucose, 25 μg/ml of each proteinogenic amino acid with the exception of phenylalanine; [H.-P. Kroll; unpublished]) with the addition of 0.4% BH broth (test medium). In the case of Enterococcus faecium L4001, heat-inactivated fetal calf serum (FCS; GibcoBRL, Germany) is added to the test medium in a final concentration of 10%. Overnight cultures of the test microbes are diluted to an OD578 of 0.001 (to 0.01 in the case of enterococci) in fresh test medium, and incubated 1:1 with dilutions of the test substances (1:2 dilution steps) in test medium (2001 final volume). The cultures are incubated at 37° C. for 18-24 hours; enterococci in the presence of 5% CO2.


The lowest substance concentration in each case at which no visible bacterial growth occurs any longer is defined as the MIC.


Alternative Method for Determining the Minimum Inhibitory Concentration (MIC)


The minimum inhibitory concentration (MIC) is the minimum concentration of an antibiotic with which the growth of a test microbe is inhibited over 18-24 h. The inhibitor concentration can in these cases be determined by standard microbiological methods with modified medium in an agar dilution test (see, for example, The National Committee for Clinical Laboratory Standards. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically; approved standard-fifth edition. NCCLS document M7-A5 [ISBN 1-56238-394-9]. NCCLS, 940 West Valley Road, Suite 1400, Wayne, Pa. 19087-1898 USA, 2000). The bacterial microbes are cultivated on 1.5% agar plates which contain 20% defibrinated horse blood. The test microbes, which are incubated overnight on Columbia blood agar plates (Becton-Dickinson), are diluted in PBS, adjusted to a microbe count of about 5×105 microbes/ml and placed dropwise (1-3 μl) on test plates. The test substances comprise different dilutions of the test substances (1:2 dilution steps). The cultures are incubated at 37° C. in the presence of 5% CO2 for 18-24 hours.

Systemic Infection with S. aureus 133


The suitability of the compounds of the invention for treating bacterial infections can be shown in various animal models. For this purpose, the animals are generally infected with a suitable virulent microbe and then treated with the compound to be tested, which is in a formulation which is adapted to the particular therapy model. The suitability of the compounds of the invention for the treatment of bacterial infections can be demonstrated specifically in a mouse sepsis model after infection with S. aureus.


For this purpose, S. aureus 133 cells are cultured overnight in BH broth (Oxoid, Germany). The overnight culture was diluted 1:100 in fresh BH broth and expanded for 3 hours. The bacteria which are in the logarithmic phase of growth are centrifuged and washed twice with a buffered physiological saline solution. A cell suspension in saline solution with an extinction of 50 units is then adjusted in a photometer (Dr Lange LP 2W). After a dilution step (1:15), this suspension is mixed 1:1 with a 10% mucine suspension. 0.2 ml of this infection solution is administered i.p. per 20 g of mouse. This corresponds to a cell count of about 1-2×106 microbes/mouse. The i.v. therapy takes place 30 minutes after the infection. Female CFW1 mice are used for the infection experiment. The survival of the animals is recorded for 6 days. The animal model is adjusted so that untreated animals die within 24 h after the infection. It was possible to demonstrate in this model a therapeutic effect of ED100=1.25 mg/kg for the compound of Example 2.


Determination of the Spontaneous Resistance Rates to S. aureus


The spontaneous resistance rates for the compounds of the invention are determined as follows: the bacterial microbes are cultivated in 30 ml of a minimal medium (18.5 mM Na2HPO4, 5.7 mM KH2PO4, 9.3 mM NH4Cl, 2.8 mM MgSO4, 17.1 mM NaCl, 0.033 μg/ml thiamine hydrochloride, 1.2 μg/ml nicotinic acid, 0.003 μg/ml biotin, 1% glucose, 25 μg/ml of each proteinogenic amino acid with the addition of 0.4% BH broth) at 37° C. overnight, centrifuged at 6000×g for 10 min and resuspended in 2 ml of a phosphate-buffered physiological NaCl solution (about 2×109 microbes/ml). 100 μl of this cell suspension, and 1:10 and 1:100 dilutions, are plated out on predried agar plates (1.5% agar, 20% defibrinated horse blood, or 1.5% agar, 20% bovine serum in 1/10 Müller-Hinton medium diluted with PBS) which contain the compound of the invention to be tested in a concentration equivalent to 5×MIC or 10×MIC, and incubated at 37° C. for 48 h. The resulting colonies (cfu) are counted.


Isolation of the Biphenomycin-Resistant S. aureus Strains RN4220BiRR and T17


The S. aureus Strain RN4220BiRR is isolated in vitro. For this purpose, 100 μl portions of an S. aureus RN4220 cell suspension (about 1.2×108 cfu/ml) are plated out on an antibiotic-free agar plate (18.5 mM Na2HPO4, 5.7 mM KH2PO4, 9.3 mM NH4Cl, 2.8 mM MgSO4, 17.1 mM NaCl, 0.033 μg/ml thiamine hydrochloride, 1.2 μg/ml nicotinic acid, 0.003 μg/ml biotin, 1% glucose, 25 μg/ml of each proteinogenic amino acid with the addition of 0.4% BH broth and 1% agarose) and on an agar plate containing 2 μg/ml biphenomycin B (10×MIC), and incubated at 37° C. overnight. Whereas about 1×107 cells grow on the antibiotic-free plate, about 100 colonies grow on the antibiotic-containing plate, corresponding to a resistance rate of 1×10−5. Some of the colonies grown on the antibiotic-containing plate are tested for the biphenomycin B MIC. One colony with an MIC of >50 μM is selected for further use, and the strain is referred to as RN4220BiR.


The S. aureus Strain T17 is isolated in vivo. CFW1 mice are infected intraperitoneally with 4×107 S. aureus 133 cells per mouse. 0.5 h after the infection, the animals are treated intravenously with 50 mg/kg biphenomycin B. The kidneys are removed from the surviving animals on day 3 after the infection. After homogenization of the organs, the homogenates are plated out as described for RN4220BiRR on antibiotic-free and antibiotic-containing agar plates and incubated at 37° C. overnight. About half the colonies isolated from the kidney show growth on the antibiotic-containing plates (2.2×106 colonies), demonstrating the accumulation of biphenomycin B-resistant S. aureus cells in the kidney of the treated animals. About 20 of these colonies are tested for the biphenomycin B MIC, and a colony with a MIC of >50 μM is selected for further cultivation, and the strain is referred to as T17.
