Description

OXAZOLIDINONE ANTIBACTERIAL
AGEI'TTS HAVING A THIOCARBONYL FUNCTIONALITY
BACKGROUND OF THE INVENTION
The present invention relates to new and useful oxazolidinone compounds and their preparations, and more particularly to oxazolidinone compounds in which the carbonyl functionality of -NH-C(O)-R is converted to a thiocarbonyl functionality, such as a thiourea -NH-C(S)-NH_" an alkyl thiourea -NH-C(S)-NH-(C,.4 alkyl), thioamide -NH-C(S)-(C,_; alkyl) or -NH-C(S)-H.
Replacement of the oxygen atom with a sulfur atom has unexpectedly improved the antimicrobial properties of the compounds. The compounds are useful antimicrobial agents, effective against a number of human and veterinary pathogens, including Gram-positive aerobic bacteria such as multiply-resistant staphylococci and streptococci, Gram-negative organisms such as H. influenzae and M. catarrahlis as well as anaerobic organisms such as bacteroides and clostridia species, and acid-fast organisms such as Mycobacterium tuberculosis and Mycobacterium avium. The compounds are particularly useful because they are effective against the latter organisms which are known to be responsible for infection in persons with AIDS.

The compounds of Formula I of this invention contain a chiral center at C5 of the isoxazoline ring, and as such there exist two enantiomers or a racemic mixture of both. This invention relates to both the enantiomers, as well as mixtures containing both the isomers. In addition, depending on substituents, additional chiral centers and other isomeric forms may be present in any of A or R, group, and this invention embraces all possible stereoisomers and geometric forms in these groups.
The compounds of this invention are useful for treatment of microbial infections in humans and other warm blooded animals, under both parenteral and oral administration.
The pharmaceutical compositions of this invention may be prepared by combining the compounds of this invention with a solid or liquid pharmaceutically acceptable carrier and, optionally, with pharmaceutically acceptable adjuvants and excipients employing standard and conventional techniques. Solid form composi-tions include powders, tablets, dispersible granules, capsules, cachets and suppositories. A solid carrier can be at least one substance which may also function as a diluent, flavoring agent, solubilizer, lubricant, suspending agent, binder, tablet disintegrating agent, and encapsulating agent. Inert solid carriers include magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, cellulosic materials, low melting wax, cocoa butter, and the like.
Liquid form compositions include solutions, suspensions and emulsions. For example, there may be provided solutions of the compounds of this invention dissolved in water and water-propylene glycol and water-polyethylene glycol systems, optionally containing suitable conventional coloring agents, flavoring agents, stabilizers and thickening agents.
Preferably, the pharmaceutical composition is provided employing conventional techniques in unit dosage form containing effective or appropriate amounts of the active component, that is, the compound according to this invention.
The quantity of active component, that is the compound according to this invention, in the pharmaceutical composition and unit dosage form thereof may be varied or adjusted widely depending upon the particular application, the potency of the particular compound, the desired concentration. Generally, the quantity of active component will range between 0.5oJo to 90010 by weight of the composition.
In therapeutic use for treating, or combatting, bacterial infections in warm-blooded animals, the compounds or pharmaceutical compositions thereof will be administered orally, parenterally and/or topically at a dosage to obtain and maintain a concentration, that is, an amount, or blood-level of active component in the animal undergoing treatment which will be antibacterially effective. Generally, such antibacterially effective amount of dosage of active component will be in the range of about 0.1 to about 100, more preferably about 3.0 to about 50 mg/kg of body weight/day. It is to be understood that the dosages may vary depending upon the requirements of the patient, the severity of the bacterial infection being treated, and the particular compound being used. Also, it is to be understood that the initial dosage administered may be increased beyond the above upper level in order to rapidly achieve the desired blood-level or the initial dosage may be smaller than the optimum and the daily dosage may be progressively increased during the course of treatment depending on the particular situation. If desired, the daily dose may also be divided into multiple doses for administration, e.g., 2-4 four times per day.
When the compounds according to this invention are administered parenteralIy, i.e., by injection, for example, by intravenous injection or by other parenteral routes of administration. Pharmaceutical compositions for parenteral administration will generally contain a pharmaceutically acceptable amount of the compound or a soluble salt (acid addition salt or base salt) dissolved in a pharmaceutically acceptable liquid carrier such as, for example, water-for-injection and a buffer to provide a suitably buffered isotonic solution, for example, having a pH of about 3.5-6. Suitable buffering agents include, for example, trisodium orthophosphate, sodium bicarbonate, sodium citrate, N-methylglucamine, L(+)-lysine and L(+)-arginine to name but a few representative buffering agents. The compound of this invention generally will be dissolved in the carrier in an amount sufficient to provide a pharmaceutically acceptable injectable concentration in the range of about 1 mg/mL to about 400 mg/mL of solution. The resulting liquid pharmaceutical composition will be administered so as to obtain the above-mentioned antibacterially effective amount of dosage. The compounds according to this invention are advantageously administered orally in solid and liquid dosage forms.
As a topical treatment an effective amount of Formula I is admixed in a pharmaceutically acceptable gel or cream vehicle that can be applied to the patient's skin at the area of treatment. Preparation of such creams and gels is well known in the art and can include penetration enhancers.
MIC Test Method The in vitro MICs of test compounds were determined by a standard agar dilution method. A stock drug solution of each analog is prepared in the preferred solvent, usually DMSO:H_,O ( 1:3). Serial 2-fold dilutions of each sample are made using I.0 ml aliquots of sterile distilled water. To each 1.0 ml aliquot of drug is added 9 ml of molten Mueller Hinton agar medium. The drug-supplemented agar is mixed, poured into 15 x 100 mm petri dishes, and allowed to solidify and dry prior to inoculation.
Vials of each of the test organisms are maintained frozen in the vapor phase of a liquid nitrogen freezer. Test cultures are grown overnight at 35°C
on the medium appropriate for the organism. Colonies are harvested with a sterile swab, and cell suspensions are prepared in Trypticase Soy broth (TSB) to equal the turbidity of a 0.5 McFarland standard. A 1:20 dilution of each suspension is made in TSB. The plates containing the drug supplemented agar are inoculated with a 0.001 ml drop of the cell suspension using a Steers replicator, yielding approximately 10"
to I05 cells per spot. The plates are incubated overnight at 35°C.
Following incubation the Minimum Inhibitory Concentration (MIC ug/ml), the lowest concentration of drug that inhibits visible growth of the organism, is read and recorded. The data is shown in Tables I and II.

As shown in Scheme 1, the intermediates II for the compounds of this invention are also intermediates disclosed in the oxazolidinone patents and published applications hereinabove incorporated by reference. The intermediates IV for this invention are final products (Examples) from the oxazolidinone patents and published applications hereinabove incorporated by reference.
As shown in Scheme 1, Step 1, and illustrated in Example 5, the isothiocyanates III can be conveniently prepared by allowing the amine intermediates (II) to react with 1,1'-thiocarbonyldi-2(1H)-pyridone in solvents such as methylene chloride at 0 to 25°C. The thioureas (Ia, R' = H, alkyI,_,,) can then be prepared as shown in Step 2 by the reaction of III with ammonia or the appropriate primary amines in solvents such as 1,4-dioxane or tetrahydrofuran at 0-50°C.
Alternatively, as illustrated in Example 6 and shown in Step 3, the thioureas can be prepared by allowing II to react with an appropriate isothiocyanate (R' - N =
C = S) in solvents such as tetrahydrofuran at 0-50°C. Thioamides (Ib, R" = H, alkyl~~) are prepared by allowing II to react with an appropriate dithioester (R"' S-C(=S)-R", Step 4 as illustrated in Example 4. This reaction is carried out in aqueous-alcoholic solvents at 0-50°C in the presence of an equivalent of an alkali metal hydroxide.
This reaction, especially when R"' is methyl or ethyl, can be catalyzed by an alkali metal fluoride.
The reaction of II with R"'-S-C(S)-R"' (R"'=CH;~, C1H5) to give Ib (Step 4) can also be carried out in the presence of a tertiary amine base such as triethylamine in solvents such as THF, dioxane or methylene chloride at 10-50°C for 3-48 hr.
When the reaction conditions are tolerated by the substituents on R lsee, for example, Examples 1-3) the thioamides (Ib, R" - H, alkyl,_,,) can also be conveniently prepared (Step 5) by allowing the appropriate amide intermediates (IV) to react with reagents such as 2,4-bis(p-methoxyphenyl)-1,3-dithiadiphosphetane-2,4-disulfide (Lawesson's Reagent) in 1,4-dioxane, benzene, toluene or tetrahydrofuran at 60-110°C; phosphorus decasulfide and sodium carbonate in tetrahydrofuran at 20-50°C
[Brillon, D., Synthetic Communications, 20, 3085 (1990)) or phosphorus decasulfide and sodium fluoride in 1,2-dimethoxyethane at 20-50°C (Hartke, K., Gerber, H.-D., J. Prakt. Chem., 338, 763 (1996)).
Compounds Ic are prepared (Step 6) by allowing II to react first with carbon disulfide and a tertiary amine base such as triethylamine in solvent mixtures containing water and methanol, ethanol or isopropanol at 10-50°C for 5-24 hours.
The resulting intermediate is treated with an alkylating agent (R"" X where X
represents bromo, iodo, alkylsulfonyloxy or arylsulfonyloxy) at 0-30°C
to give compounds Ic. In Step 7, compounds Ic are allowed to react with alkali metal alkoxide such as sodium methoxide or potassium ethoxide in the corresponding alkanol as solvent. This reaction is conveniently carried out at the reflux temperature of the aIkanol for 1-24 hr.
