Description

QUINOLINECARBOXAMIDES AS ANTIVIRAL AGENTS
FIELD OF THE INVENTION The present invention provides 4-oxo- 1 ,4-dihydro-3-quinolinecarboxamide derivatives. These compounds are useful as antiviral agents, in particular, as agents against viruses of the herpes family.
BACKGROUND OF THE INVENTION The herpesviruses comprise a large family of double stranded DNA viruses. They are also a source of the most common viral illnesses in man. Eight of the herpes viruses, herpes simplex virus types 1 and 2 (HSV-1 and HSV-2), varicella zoster virus (VZV), human cytomegalovirus (HCMV), epstein-Barr virus (EBV), and human herpes viruses 6, 7, and 8 (HHV-6, HHV-7, and (HHV-8), have been shown to infect humans. HSV-1 and HSV-2 cause herpetic lesions on the lips and genitals, respectively. They also occasionally cause infections of the eye and encephalitis. HCMV causes birth defects in infants and a variety of diseases in immunocompromised patients such as retinitis, pneumonia, and gastrointestinal disease. VZV is the causitive agent of chicken pox and shingles. EBV causes infectious mononucleosis. It can also cause lymphomas in immunocompromised patients and has been associated with Burkitt's lymphoma, nasopharyngeal carcinoma, and Hodgkins disease. HHV-6 is the causitive agent of roseola and may be associated with multiple sclerosis and chronic fatigue syndrome. HHV-7 disease association is unclear, but it may be involved in some cases of roseola. HHV-8 has been associated with Karposi s sarcoma, body cavity based lymphomas, and multiple myeloma. Compounds of the present invention are distinct from other hydro xyquinoline antiviral agents in that the 4-substituent on the benzyl amide of the present invention (i.e. the chloro, bromo, cyano, or nitro substituent) provides significantly improved antiviral activity.
Certain compounds of formula (I) also possess unique substituents R4 that provide improved antiviral activity.

In cases where compounds are sufficiently basic or acidic to form stable nontoxic acid or base salts, administration of the compounds as salts may be appropriate. Examples of pharmaceuticaUy acceptable salts are organic acid addition salts formed with acids which form a physiological acceptable anion. for example, tosylate. methanesuU'onate, acetate, citrate, malonate. tartarate, succinate. benzoate. ascorbate, etoglutarate, and glycerophosphate. Suitable inorganic salts may also be formed, including hydrochloride. sulfate, nitrate, bicarbonate, and carbonate salts.
PharmaceuticaUy acceptable salts may be obtained using standard procedures weU known in the art, for example by reacting a sufficiently basic compound such as an amine with a suitable acid affording a physiologicaUy acceptable anion. AlkaU metal (for example, sodium, potassium or hthium) or alkaline earth metal (for example calcium) salts of carboxyUc acids can also be made.
Compounds of the present invention can conveniently be administered in a pharmaceutical composition containing the compound in combination with a suitable excipient. the composition being useful in combating viral infections. Pharmaceutical compositions containing a compound appropriate for antiviral use are prepared by methods and contain excipients which are weU known in the art. A generally recognized compendium of such methods and ingredients is Remington's Pharmaceutical Sciences by E.W. Martin (Mark Publ. Co., 15th Ed.. 1975). The compounds and compositions of the present invention can be administered parenteraUy (for example, by intravenous, intraperitoneal or intramuscular injection), topicaUy. oraUy. or rectally. depending on whether the preparation is used to treat internal or external viral infections.
For oral therapeutic administration, the active compound may be combined with one or more excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers, and the like. Such compositions and preparations should contain at least 0.1 % of active compound. The percentage of the compositions and preparations may. of course, be varied and may conveniently be between about 2 to about 60% of the weight of a given unit dosage form. The amount of active compound in such therapeuticaUy useful compositions is such that an effective dosage level wiU be obtained.
The tablets, troches, piUs, capsules, and the like may also contain the foUowing: binders such as gum tragacanth, acacia, corn starch or gelatin: excipients such as dicalcium phosphate; a disintegrating agent such as corn starch, potato starch, alginic acid and the like; a lubricant such as magnesium stearate: and a sweetening agent such as sucrose, fructose, lactose or aspartame or a flavoring agent such as peppermint, oU of wintergreen, or cherry flavoring may be added. When the unit dosage form is a capsule, it may contain, in addition to materials of the above type, a Uquid carrier, such as a vegetable oU or a polyethylene glycol. Various other materials may be present as coatings or to otherwise modU'y the physical form of the soUd unit dosage form. For instance, tablets, pills, or capsules may be coated with gelatin, wax, sheUac or sugar and the like. A syrup or elixir may contain the active compound, sucrose or fructose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavoring such as cherry or orange flavor. Of course, any material used in preparing any unit dosage form should be pharmaceuticaUy acceptable and substantiaUy non-toxic in the amounts employed. In addition, the active compound may be incorporated into sustained-release preparations and devices.
The compounds or compositions can also be administered intravenously or intraperitoneally by infusion or injection. Solutions of" the active compound or its salts can be prepared in water, optionaUy mixed with a nontoxic surfactant. Dispersions can also be prepared in glycerol, Uquid polyethylene glycols, triacetin, and mixtures thereof and in oUs. Under ordinary conditions of storage and use, these preparations contain a preservative to prevent the growth of microorganisms.
Pharmaceutical dosage forms suitable for injection or infusion can include sterUe aqueous solutions or dispersions or sterUe powders comprising the active ingredient which are adapted for the extemporaneous preparation of sterUe injectable or infusible solutions or dispersions, optionaUy encapsulated in Uposomes. In aU cases, the ultimate dosage form should be sterUe, fluid and stable under the conditions of manufacture and storage. The Uquid carrier or vehicle can be a solvent or Uquid dispersion medium comprising, for example, water, ethanol, a polyol (for example, glycerol, propylene glycol, liquid polyethylene glycols, and the like), vegetable oils, nontoxic glyceryl esters, and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the formation of Uposomes, by the maintenance of the required particle size in the case of dispersions or by the use of surfactants. The prevention of the action of microorganisms can be brought about by various antibacterial and antif'ungal agents, for example, parabens. chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it wiU be preferable to include isotonic agents, for example, sugars, buffers or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the compositions of agents delaying absorption, for example, aluminum monostearate and gelatin.
SterUe injectable solutions can be prepared by incorporating the active compound in the required amount in the appropriate solvent with various of the other ingredients enumerated above, as required, foUowed by filter sterilization. In the case of sterUe powders for the preparation of sterUe injectable solutions, the preferred methods of preparation are vacuum drying and the freeze drying techniques, which yield a powder of the active ingredient plus any additional desired ingredient present in the previously sterile-filtered solutions. For topical administration, the present compounds may be appUed in pure form, i.e.. when they are Uquids. However, it will generaUy be desirable to administer them to the skin as compositions or formulations, in combination with a dermatologically acceptable carrier, which may be a soUd or a Uquid.
Useful soUd carriers include finely divided solids such as talc. clay, microcrystalline ceUulose, siUca. alumina and the like. Useful Uquid carriers include water, alcohols or glycols or water-alcohol/glycol blends, in which the present compounds can be dissolved or dispersed at effective levels, optionaUy with the aid of non-toxic surfactants. Adjuvants such as fragrances and additional antimicrobial agents can be added to optimize the properties for a given use. The resultant Uquid compositions can be appUed from absorbent pads, used to impregnate bandages and other dressings, or sprayed onto the affected area using pump-type or aerosol sprayers. Thickeners such as synthetic polymers, fatty acids, fatty acid salts and esters, fatty alcohols. modUied ceUuloses or modified mineral materials can also be employed with Uquid carriers to form spreadable pastes, gels, ointments, soaps, and the like, for appUcation directly to the skin of the user. Examples of useful dermatological compositions which can be used to deUver the compounds of formula I to the skin are known to the art: for example, see Jacquet et al. (U.S. Pat. No. 4.608392), Geria (U.S. Pat. No. 4.992,478). Smith et al. (U.S. Pat. No. 4,559,157) and Wortzman (U.S. Pat. No. 4.820.508).
Useful dosages of the compounds of formula I can be determined by comparing their in vitro activity, and in vivo activity in animal models. Methods for the extrapolation of effective dosages in mice, and other animals, to humans are known to the art: for example, see U.S. Pat. No. 4,938,949. The compound is conveniently administered in unit dosage form; for example, containing 5 to 1000 mg, conveniently 10 to 750 mg, most conveniently, 50 to 500 mg of active ingredient per unit dosage form. The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itseU' may be further divided, e.g., into a number of discrete loosely spaced administrations: such as multiple inhalations from an insufflator or by appUcation of a pluraUty of drops into the eye.
For internal infections, the compositions can be administered oraUy or parenteraUy at dose levels, calculated as the free base, of" about 0.1 to 300 mg/kg, preferably 1.0 to 30 mg/kg of mammal body weight, and can be used in man in a unit dosage form, administered one to four times daUy in the amount of 1 to 1000 mg per unit dose.
For parenteral administration or for administration as drops, as for eye infections, the compounds are presented in aqueous solution in a concentration of from about 0.1 to about 10%, more preferably about 0J to about 1%. The solution may contain other ingredients, such as emulsUiers, antioxidants or buffers.
GeneraUy, the concentration of" the compound(s) of" formula I in a Uquid composition, such as a lotion, wUl be from about 0J-25 wt-%, preferably from about 0.5-10 wt-%. The concentration in a semi-soUd or soUd composition such as a gel or a powder wiU be about 0J-5 wt-%, preferably about 0.5-2.5 wt-%. The exact regimen for administration of the compounds and compositions disclosed herein wiU necessarUy be dependent upon the needs of the individual subject being treated, the type of treatment and, of" course, the judgment of the attending practitioner.
The antiviral activity of" a compound of the invention can be determined using pharmacological models which are weU known to the art, or using Test A described below. The compounds of formula (I) and pharmaceuticaUy acceptable salts thereof" are useful as antiviral agents. Thus, they are useful to combat viral infections in animals, including man. The compounds are generaUy active against herpes viruses, and are particularly useful against the variceUa zoster virus, the Epstein-Barr virus, the herpes simplex virus, the human herpes virus type 8 (HHV-8) and the cytomegalovirus (CMV). WhUe many of the compounds of the present invention have shown activity against the CMV polymerase, these compounds may be active against the cytomegalovirus by this or other mechanisms of action. Thus, the description below of" these compounds' activity against the CMV polymerase is not meant to limit the present invention to a specUic mechanism of action. Test A
The HCMV polymerase assay is performed using a scintillation proximity assay (SPA) as described in several references, such as N.D. Cook, et al., Pharmaceutical Manufacturing International, pages 49-53 (1992); K. Takeuchi, Laboratory Practice, September issue (1992); US Patent No. 4,568,649 (1986); which are incorporated by reference herein. Reactions are performed in 96-weU plates. The assay is conducted in 100 μl volume with 5.4 mM HEPES (pH 7.5), 1 1.7 mM KCI, 4.5 mM MgCl2, 0.36 mg/ml BSA, and 90 nM 3H-dTTP. Assays are run with and without CHAPS, (3-[(3-Cholamidopropyl)- dimethylammonio]- l-propane-suU"onate) at a final concentration of 2 mM. HCMV polymerase is dUuted in enzyme dUution buffer containing 50% glycerol, 250 mM NaCl, 10 mM HEPES (pH 7.5), 100 μg/ml BSA, and 0.01 % sodium azide. The HCMV polymerase. which is expressed in recombinant baculovirus-infected SF-9 ceUs and purified according to Uterature procedures, is added at 10% (or 10 μl) of the final reaction volume, i.e., 100 μl. Compounds are dUuted in 50% DMSO and 10 μl are added to each weU. Control wells contain an equivalent concentration of DMSO. Unless noted otherwise, reactions are initiated via the addition of 6 nM biotinylated poly(dA)-oUgo(dT) template/primer to reaction mixtures containing the enzyme, substrate, and compounds of interest. Plates are incubated in a 25 C or 37 C H?O bath and terminated via the addition of 40 μl/reaction of 0.5 M EDTA (pH 8) per well. Reactions are terminated within the time-frame during which substrate incorporation is linear and varied depending upon the enzyme and conditions used, i.e., 30 min. for HCMV polymerase. Ten μl of streptavidin-SPA beads (20 mg/ml in PBS/10% glycerol) are added foUowing termination of the reaction. Plates are incubated 10 min. at 37 C, then equUibrated to room temperature, and counted on a Packard Topcount. Linear regressions are performed and IC50's are calculated using computer software.
A modUied version of the above HCMV polymerase assay is performed as described above, but with the foUowing changes: Compounds are diluted in 100% DMSO untU final dUution into assay buffer. In the previous assay, compounds are dUuted in 50% DMSO. 4.5 mM dithiotherotol (DTT) is added to the polymerase buffer. Also, a dUferent lot of CMV polymerase is used, which appears to be more active resulting in a more rapid polymerase reaction. Results of the testing of" representative compounds of formula I in this assay are shown in Table 1 below. Table 1. Biological Data polymerase IC50 (μM)
