Description
FIELD OF THE INVENTION

The present invention relates to 9-aminocarbonylsubstituted derivatives of glycylcyclines which are useful as antibiotic agents and exhibit antibacterial activity against a wide spectrum of organisms including organisms which are resistant to tetracyclines and other antibiotics.


BACKGROUND OF THE INVENTION

Since 1947 a variety of tetracycline antibiotics have been synthesized and described for the treatment of infectious diseases in man and animals. Tetracyclines inhibit protein synthesis by binding to the 30S subunit of the bacterial ribosome preventing binding of aminoacyl RNA (Chopra, Handbook of Experimental Pharmacology, Vol. 78, 317-392, Springer-Verlag, 1985). Resistance to tetracyclines has emerged among many clinically important microorganisms which limit the utility of these antibiotics. There are two major mechanisms of bacterial resistance to tetracyclines: a) energy-dependent efflux of the antibiotic mediated by proteins located in the cytoplasmic membrane which prevents intracellular accumulation of tetracycline (S. B. Levy, et al., Antimicrob. Agents Chemotherapy 33, 1373-1374 (1989); and b) ribosomal protection mediated by a cytoplasmic protein which interacts with the ribosome such that tetracycline no longer binds or inhibits protein synthesis (A. A. Salyers, B. S. Speers and N. B. Shoemaker, Mol. Microbiol, 4:151-156, 1990). The efflux mechanism of resistance is encoded by resistance determinants designated tetA-tetL. They are common in many Gram-negative bacteria (resistance genes Class A-E), such as Enterobacteriaceae, Pseudomonas, Haemophilus and Aeromonas, and in Gram-positive bacteria (resistance genes Class K and L), such as Staphylococcus, Bacillus and Streptococcus. The ribosomal protection mechanism of resistance is encoded by resistance determinants designated TetM, N and O, and is common in Staphylococcus, Streptococcus, Campylobacter, Gardnerella, Haemophilus and Mycoplasma (A. A. Salyers, B. S. Speers and N. B. Shoemaker, Mol. Microbiol, 4:151-156 1990).


A particularly useful tetracycline compound is 7-(dimethylamino)-6-demethyl-6-deoxytetracycline, known as minocycline (see U.S. Pat. No. 3,148,212, U.S. Pat. No. RE 26,253 and U.S. Pat. No. 3,226,436 discussed below). However, strains harboring the tetB (efflux in gram-negative bacteria) mechanism, but not tetK (efflux in Staphylococcus) are resistant to minocycline. Also, strains carrying tetM (ribosomal protection) are resistant to minocycline.


Duggar, U.S. Pat. No. 2,482,055, discloses the preparation of Aureomycin® by fermentation which have antibacterial activity. Growich et al., U.S. Pat. No. 3,007,965, disclose improvements to the fermentation preparation. Beereboom et al., U.S. Pat. No. 3,043,875 discloses tetracycline derivatives Boothe et al., U.S. Pat. No. 3,148,212, reissued as U.S. Pat. No. RE 26,253, and Petisi et al., U.S. Pat. No. 3,226,436, discloses tetracycline derivatives which are useful for treating bacterial infections. Blackwood et al., U.S. Pat. No. 3,200,149 discloses tetracycline derivatives which possess microbiological activity. Petisi et al., U.S. Pat. No. 3,338,963 discloses tetracycline compounds which have broad-spectrum antibacterial activity. Bitha et al., U.S. Pat. No. 3,341,585 discloses tetracycline compounds which have broad-spectrum antibacterial activity. Shu, U.S. Pat. No. 3,360,557 discloses 9-hydroxytetracyclines which have been found to possess antibacterial activity. Zambrano, U.S. Pat. No. 3,360,561 discloses a process for preparing 9-nitrotetracyclines. Martell et al., U.S. Pat. No. 3,518,306 discloses tetracyclines which possess in vivo antibacterial activity.


In U.S. Pat. No. 5,021,407 a method of overcoming the resistance of tetracycline resistant bacteria is disclosed. The method involves utilizing a blocking agent compound in conjunction with a tetracycline type antibiotic. This patent does not disclose novel tetracycline compounds which themselves have activity against resistant organisms. Described in U.S. Pat. No. 5,494,903 are 7-substituted-9-substituted amino-6-demethyl-6-deoxytetracyclines which have broad spectrum antibacterial activity.


Despite the advances being made to overcome the resistance of tetracycline resistant bacteria, there remains a need for newer and better antibiotics to overcome the increasing incidence of resistance. The present invention provides such antibiotics.


In summary, none of the above patents teach or suggest the novel derivatives of glycylcyclines of this application.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The compounds of this invention may be prepared according to the following schemes: (1) from commercially available starting materials or: (2) from known starting materials which can be prepared as described in literature procedures or: (3) from new intermediates described in the schemes and experimental procedures.


The synthesis of acyloxy intermediate 8 is shown in Scheme 1. Reaction of amine R4NH2, preferably t-butylamine, with ester 1 provides the substituted amino ester 2. Preparation of the intermediate 4 is accomplished by using Proton Sponge as base to effect the acylation of substituted amino ester 2 with chloromethyl chloroformate 3. Treatment of intermediate 4 with the tetrabutylammonium salt 5 of carboxylic acids gives the benzyl protected acyloxy intermediate 6. The benzyl protecting group is removed by catalytic reduction to give carboxylic acid 7 which is activated to a mixed anhydride with chloroformate ClCO2R12 where R12 is alkyl of 1 to 6 carbon atoms, for example iso-butyl chloroformate to give acyloxycarbamate intermediate 8. In an alternate route, silyl esters may optionally be used in place of the benzyl ester of intermediate 4, treating with the appropriate carboxylic acid followed by deblocking the silyl ester with tetrabutylammonium fluoride or magnesium bromide to afford carboxylic acid 7. Optionally, carboxylic acid 7 may be activated through the use of coupling agents not limited to di-t-butyl dicarbonate (Boc2O); e.g., benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (also known asBop); benzotriazole-1-yl-oxy-tris-pyrrolidino-phosphonium hexafluorophosphate (also known as PyBop); O-benzotriazole-N,N,N′,N′-tetramethyl-uronium-hexafluoro-phosphate (HBTU); Bromotris-pyrollidino-phosphonium hexafluorophosphate; 2-Chloro-N-methylpyridinium iodide (CMPI); dicyclohexylcarbodiimide (DCC); 1,3-diisopropylcarbodiimide (DIC); 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (EDC); or Carbonyl diimidazole.

As shown in Scheme 2, reaction of activated acyloxycarbamate intermediate 8 with 7,8-disubstituted-9-aminotetracycline 9 in the presence of triethylamine and DMPU gives acyloxycarbamate 10.
embedded image


Additional acyloxy carbamate compounds may be synthesized via routes as shown in Schemes 3 and 4. Treatment of chloromethyl chloroformate 3 with ethanethiol in the presence of triethylamine (TEA) gives carbonothioate 11. Compound 12 is prepared by reacting carbonothioate 11 with carboxylic acid tetrabutylammonium salt 5 in tetrahydrofuran. Chlorination of compound 12 with sulfuryl chloride in the presence of catalytic amount of boron trifluoroetherate affords chloro intermediate 13 (using the methods described in M. Folkmann and F. J. Lund, Synthesis, December 1990, 1159-1166).

As further seen in Scheme 4 acyloxycarbamates 16 and 17 where R4 is preferably n-butyl or n-propyl are synthesized by treatment of either 14 or 15 where R4 is preferably n-butyl or n-propyl with the chloro intermediate 13 to give acyloxycarbamates 16 and 17 respectively.
embedded image


As shown in Scheme 5, carbamates of glycylcycline where R4 is preferably propyl 18 may also be prepared by reaction with chloro intermediate 19 in the presence of an alkali metal carbonate preferably sodium carbonate, and DMPU in acetonitrile to afford preferred compounds (21 and 22).
embedded imageembedded image


As shown in Scheme 6, reaction of chloro intermediate 13 with 7,8-disubstituted-9-aminotetracycline 9 in the presence of triethylamine and DMPU gives carbamate 23.


As further shown in Scheme 7, compounds of Formula I may generally be prepared by removal of the benzyl protecting group from benzyl protected acyloxy intermediate 24 to give carboxylic acid 25 which is activated to a mixed anhydride with a chloroformate ClCO2R12 where R12 is alkyl of 1 to 6 carbon atoms, for example iso-butyl chloroformate to give acyloxycarbamate intermediate 26. Further reaction of 7,8-disubstituted-9-aminotetracycline 9 with acyloxycarbamate mixed anhydride intermediate 26 in the presence of triethylamine and DMPU affords compounds of Formula (I).

Reactions are performed in a solvent appropriate to the reagents and materials employed and suitable for the transformation being effected. It is understood by those skilled in the art of organic synthesis that the various functionalities present on the molecule must be consistent with the chemical transformations proposed. This may necessitate judgement as to the order of synthetic steps, protecting groups, if required, and deprotection conditions. Substituents on the starting materials may be incompatible with some of the reaction conditions. Such restrictions to the substituents which are compatible with the reaction conditions will be apparent to one skilled in the art.


Some of the compounds of the hereinbefore described schemes have center of asymmetry. The compounds may, therefore, exist in at least two and often more stereoisomeric forms. The present invention encompasses all stereoisomers of the compounds whether free from other stereoisomers or admixed with other stereoisomers in any proportion and thus includes, for instance, racemic mixture of enantiomers as well as the diastereomeric mixture of isomers. The absolute configuration of any compound may be determined by conventional X-ray crystallography.


The compounds of the invention may be obtained as metal complexes such as aluminum, calcium, iron, magnesium, manganese and complex salts; inorganic and organic salts and corresponding Mannich base adducts using methods known to those skilled in the art (Richard C. Larock, Comprehensive Organic Transformations, VCH Publishers, 411-415, 1989). Preferably, the compounds of the invention are obtained as inorganic salts such as hydrochloric, hydrobromic, hydroiodic, phosphoric, nitric or sulfate; or organic salts such as acetate, benzoate, citrate, cysteine or other amino acids, fumarate, glycolate, maleate, succinate, tartrate alkylsulfonate or arylsulfonate. In all cases, the salt formation occurs with the C(4)-dimethylamino group. The salts are preferred for oral and parenteral administration.


Standard Pharmacological Test Procedures


Methods for in Vitro Antibacterial Evaluation


The Minimum Inhibitory Concentration (MIC)


Antimicrobial susceptibility testing. The in vitro activities of the antibiotics are determined by the broth microdilution method as recommended by the National Committee for Clinical Laboratory Standards (NCCLS) (1). Mueller-Hinton II broth (MHBII)(BBL Cockeysville, Md.) is the medium employed in the testing procedures. Microtiter plates containing serial dilutions of each antimicrobial agent are inoculated with each organism to yield the appropriate density (105 CFU/ml) in a 100 μl final volume. The plates are incubated for 18-22 hours at 35° C. in ambient air. The minimal inhibitory concentration for all isolates is defined as the lowest concentration of antimicrobial agent that completely inhibits the growth of the organism as detected by the unaided eye.

When the compounds of the invention are employed as antibacterials, they can be combined with one or more pharmaceutically acceptable carriers, for example, solvents, diluents and the like, and may be administered orally in such forms as tablets, capsules, dispersible powders, granules, or suspensions containing, for example, from about 0.05 to 5% of suspending agent, syrups containing, for example, from about 10 to 50% of sugar, and elixirs containing, for example, from about 20 to 50% ethanol, and the like, or parenterally in the form of sterile injectable solutions or suspensions containing from about 0.05 to 5% suspending agent in an isotonic medium. Such pharmaceutical preparations may contain, for example, from about 25 to about 90% of the active ingredient in combination with the carrier, more usually between about 5% and 60% by weight.


An effective amount of compound from 2.0 mg/kg of body weight to 100.0 mg/kg of body weight may be administered one to five times per day via any typical route of administration including but not limited to oral, parenteral (including subcutaneous, intravenous, intramuscular, intrasternal injection or infusion techniques), topical or rectal, in dosage unit formulations containing conventional non-toxic pharmaceutically acceptable carriers, adjuvants and vehicles. It will be understood, however, that the specific dose level and frequency of dosage for any particular patient may be varied and will depend upon a variety of factors including the activity of the specific compound employed, the metabolic stability and length of action of that compound, the age, body weight, general health, sex, diet, mode and time of administration, rate of excretion, drug combination, the severity of the particular condition, and the host undergoing therapy.


These active compounds may be administered orally as well as by intravenous, intramuscular, or subcutaneous routes. Solid carriers include starch, lactose, dicalcium phosphate, microcrystalline cellulose, sucrose and kaolin, while liquid carriers include sterile water, polyethylene glycols, non-ionic surfactants and edible oils such as corn, peanut and sesame oils, as are appropriate to the nature of the active ingredient and the particular form of administration desired. Adjuvants customarily employed in the preparation of pharmaceutical compositions may be advantageously included, such as flavoring agents, coloring agents, preserving agents, and antioxidants, for example, vitamin E, ascorbic acid, BHT and BHA.


The preferred pharmaceutical compositions from the standpoint of ease of preparation and administration are solid compositions, particularly tablets and hard-filled or liquid-filled capsules. Oral administration of the compounds is preferred. These active compounds may also be administered parenterally or intraperitoneally. Solutions or suspensions of these active compounds as a free base or pharmacologically acceptable salt can be prepared in water suitably mixed with a surfactant such as hydroxy-propylcellulose. Dispersions can also be prepared in glycerol, liquid, polyethylene glycols and mixtures thereof in oils. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.


The pharmaceutical forms suitable for injectable use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacterial and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (e.g., glycerol, propylene glycol and liquid polyethylene glycol), suitable mixtures thereof, and vegetable oil.


The present invention further provides a method of treating bacterial infections in warm-blooded animals including man, which comprises providing to the afflicted warm-blooded animals an antibacterially effective amount of a compound or a pharmaceutical composition of a compound of the invention.


The invention will be more fully described in conjunction with the following specific examples which are not to be construed as limiting the scope of the invention.
