(56) The compounds can be co-administered with one or more other agents for the treatment or prevention of RSV infection. The other agents can be formulated separately, and administered either at the same or different time as the compounds of the instant invention. The other agents can be co-formulated with the compounds of the instant invention to give a combination dosage form.

(57) Pharmaceutical Compositions and Modes of Administration

(58) The invention also provides a pharmaceutical composition comprising a compound of formula (I) and a pharmaceutically acceptable vehicle, excipient or carrier, and the form of this composition can be suitable for a number of different modes of administration to a patient as set forth below.

(59) The pharmaceutical composition may further comprise or be administered in combination with one or more other RSV antiviral agents such as Virazole, BMS-4337715, TMC3531216, MDT-637 (formerly VP-14637), GS-5806, RSV604, ALNRSV01, AL-8176 (or ALS-8176) and/or other agents that may be developed as inhibitors of viral entry, assembly, replication, egress or host-virus interactions

(60) The term composition is intended to include the formulation of an active ingredient with conventional vehicles, carriers and excipients, and also with encapsulating materials as the carrier, to give a capsule in which the active ingredient (with or without other carriers) is surrounded by the encapsulation carrier. Any carrier must be pharmaceutically acceptable meaning that it is compatible with the other ingredients of the composition and is not deleterious to a subject. The compositions of the present invention may contain other therapeutic agents as described above, and may be formulated, for example, by employing conventional solid or liquid vehicles or diluents, as well as pharmaceutical additives of a type appropriate to the mode of desired administration (for example, excipients, binders, preservatives, stabilizers, flavours and the like) according to techniques such as those well known in the art of pharmaceutical formulation (see, for example, Remington: The Science and Practice of Pharmacy, 21st Ed., 2005, Lippincott Williams & Wilkins).

(61) The pharmaceutical composition includes those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, sub-cutaneous and intravenous) administration or in a form suitable for administration by inhalation or insufflation.

(62) The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical compositions and unit dosages thereof, and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, or capsules filled with the same, all for oral use, in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use.

(63) Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles, and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.

(64) For preparing pharmaceutical compositions from the compounds of the present invention, pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories, and dispensable granules. A solid carrier can be one or more substances which may also act as diluents, flavouring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or an encapsulating material.

(65) Suitable vehicles, carriers or excipients include magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter and the like. The term preparation is intended to include the formulation of the active compound with an encapsulating material as the carrier by providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.

(66) Liquid form preparations include solutions, suspensions, and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution.

(67) Sterile liquid form compositions include sterile solutions, suspensions, emulsions, syrups and elixirs. The active ingredient can be dissolved or suspended in a pharmaceutically acceptable carrier, such as sterile water, sterile organic solvent or a mixture of both.

(68) The compositions according to the present invention may thus be formulated for parenteral administration (for example, by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles, and may contain formulation agents such as suspending, stabilising and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilisation from solution, for constitution with a suitable vehicle, for example, sterile, pyrogen-free water, before use.

(69) Pharmaceutical forms suitable for injectable use include sterile injectable solutions or dispersions, and sterile powders for the extemporaneous preparation of sterile injectable solutions. They should be stable under the conditions of manufacture and storage and may be preserved against oxidation and the contaminating action of microorganisms such as bacteria or fungi.

(70) The solvent or dispersion medium for the injectable solution or dispersion may contain any of the conventional solvent or carrier systems for the compounds, and may contain, for example, water, ethanol, polyol (for example, glycerol, propylene glycol and liquid polyethylene glycol and the like), suitable mixtures thereof, and vegetable oils.

(71) Pharmaceutical forms suitable for injectable use may be delivered by any appropriate route including intravenous, intramuscular, intracerebral, intrathecal, epidural injection or infusion.

(72) Sterile injectable solutions are prepared by incorporating the active compounds in the required amount in the appropriate solvent with various other ingredients such as these enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the various sterilised active ingredient into a sterile vehicle which contains the basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, preferred methods of preparation are vacuum drying or freeze-drying of a previously sterile-filtered solution of the active ingredient plus any additional desired ingredients.

(73) When the active ingredients are suitably protected they may be orally administered, for example, with an inert diluent or with an assimilable edible carrier, or they may be enclosed in hard or soft shell gelatin capsule, or they may be compressed into tablets, or they may be incorporated directly with the food of the diet. For oral therapeutic administration, the active compound may be incorporated with excipients and used in the form of ingestible tablets, buccal tablets, troches, capsules, elixirs, suspensions, syrups, wafers and the like.

(74) The amount of active compound in therapeutically useful compositions should be sufficient that a suitable dosage will be obtained.

(75) The tablets, troches, pills, capsules and the like may also contain the components as listed hereafter: a binder such as gum, 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 a sucrose, lactose or saccharin; or a flavouring agent such as peppermint, oil of wintergreen, or cherry flavouring. When the dosage unit form is a capsule, it may contain, in addition to materials of the above type, a liquid carrier.

(76) Various other materials may be present as coatings or to otherwise modify the physical form of the dosage unit. For instance, tablets, pills, or capsules may be coated with shellac, sugar or both. A syrup or elixir may contain the active compound, sucrose as a sweetening agent, methyl and propylparabens as preservatives, a dye and flavouring such as cherry or orange flavour. Of course, any material used in preparing any dosage unit form should be pharmaceutically pure and substantially non-toxic in the amounts employed. In addition, the active compound(s) may be incorporated into sustained-release preparations and formulations, including those that allow specific delivery of the active peptide to specific regions of the gut.

(77) Aqueous solutions suitable for oral use can be prepared by dissolving the active component in water and adding suitable colorants, flavours, stabilising and thickening agents, as desired. Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well-known suspending agents.

(78) Pharmaceutically acceptable carriers and/or diluents include any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like.

(79) Also included are solid form preparations that are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions, and emulsions. These preparations may contain, in addition to the active component, colorants, flavours, stabilisers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilising agents and the like.

(80) For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch. Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilising agents, dispersing agents, suspending agents, thickening agents, or colouring agents.

(81) Formulations suitable for topical administration in the mouth include lozenges comprising active agent in a flavoured base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.

(82) Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multidose form. In the latter case of a dropper or pipette, this may be achieved by the patient administering an appropriate, predetermined volume of the solution or suspension.

(83) In the case of a spray, this may be achieved for example by means of a metering atomising spray pump. To improve nasal delivery and retention the compounds according to the invention may be encapsulated with cyclodextrins, or formulated with other agents expected to enhance delivery and retention in the nasal mucosa.

(84) Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurised pack with a suitable propellant such as a chlorofluorocarbon (CFC) for example dichlorodifluoromethane, trichlorofluoromethane, or dichlorotetrafluoroethane, a hydrofluorocarbon (HFC) for example hydrofluoroalkanes (HFA), carbon dioxide, or other suitable gas.

(85) The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.

(86) Alternatively the active ingredients may be provided in the form of a dry powder, for example a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, for example gelatin, or blister packs from which the powder may be administered by means of an inhaler.

(87) In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 5 to 10 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization.

(88) When desired, formulations adapted to give sustained release of the active ingredient may be employed.

(89) The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules, and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.

(90) It is especially advantageous to formulate parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subjects to be treated; each unit containing a predetermined quantity of active material calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specification for the novel dosage unit forms of the invention are dictated by and directly dependent on (a) the unique characteristics of the active material and the particular therapeutic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active material for the treatment of viral infection in living subjects having a diseased condition in which bodily health is impaired as herein disclosed in detail.

(91) The invention also includes the compounds in the absence of carrier where the compounds are in unit dosage form.

(92) Liquids or powders for intranasal administration, tablets or capsules for oral administration and liquids for intravenous administration are the preferred compositions.

(93) The compounds as set forth above can be useful in a method of inhibiting RSV or in treating or preventing an RSV infection of other infections caused by related members of the paramyxovirus family such as mumps virus, human parainfluenzaviruses, and Nipah and hendra virus. The reference to RSV as used hereinbelow also include these related members or the paramyxovirus family compounds can also be used to treat an RSV disease or reduce exacerbation of an underlying or pre-existing respiratory disease wherein RSV infection is a cause of said exacerbation. The RSV disease may include bronchiolitis or pneumonia. The underlying or pre-existing respiratory diseases or conditions may include asthma, chronic obstructive pulmonary disease (COPD) and immunosuppression such as immunosuppression experienced by bone marrow transplant recipients.

(94) Treatment may be therapeutic treatment or prophylactic treatment or prevention. Generally, the term treating means affecting a subject, tissue or cell to obtain a desired pharmacological and/or physiological effect and includes: (a) inhibiting the viral infection or RSV disease, such as by arresting its development or further development; (b) relieving or ameliorating the effects of the viral infection or RSV disease, such as by causing regression of the effects of the viral infection or RSV disease; (c) reducing the incidence of the viral infection or RSV disease or (d) preventing the viral infection or RSV disease from occurring in a subject, tissue or cell predisposed to the viral infection or RSV disease or at risk thereof, but has not yet been diagnosed with a protective pharmacological and/or physiological effect so that the viral infection or RSV disease does not develop or occur in the subject, tissue or cell.

(95) The term subject refers to any animal, in particular mammals such as humans, having a disease which requires treatment with the compound of formula (I). Particularly preferred treatment groups include at risk populations such as hospitalised subjects, the elderly, high-risk adults and infants. In one embodiment of the invention, an effective amount of the above compounds, or pharmaceutical compositions thereof, is administered to a patient or subject in need thereof.

(96) The term administering or administered should be understood to mean providing a compound or pharmaceutical composition of the invention to a subject suffering from or at risk of the disease or condition to be treated or prevented.

(97) As indicated above, although the invention has been described with particular reference to treating RSV infections and diseases, more particularly human and animal RSV infections or diseases, it will be appreciated that the invention may also be useful in the treatment of other viruses of the sub-family Pneumovirinae, more particularly, the genera Pneumovirus and Metapneumovirus.

(98) Dosages

(99) The term therapeutically effective amount refers to the amount of the compound of formula (I) that will elicit the biological or medical response of a subject, tissue or cell that is being sought by the researcher, veterinarian, medical doctor or other clinician.

(100) By effective amount is generally considered that amount that will be effective to treat the condition sought to be treated, or to inhibit RSV, and this effective amount is variable based on a variety of factors including age, size and condition of the patient being treated. Accordingly, one skilled in the art would be readily able to determine the specific effective amount for each patient being treated for RSV, an RSV-related condition, or to inhibit RSV in a given case.

(101) In the treatment of RSV infections or diseases, an appropriate dosage level will generally be about 0.01 to about 500 mg per kg subject body weight per day which can be administered in single or multiple doses. The dosage may be selected, for example, to any dose within any of these ranges, for therapeutic efficacy and/or symptomatic adjustment of the dosage to the subject to be treated.

(102) As indicated above, it will be understood that the specific dose level and frequency of dosage for any particular subject 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 subject undergoing therapy.

(103) Methods of Preparation

(104) The compounds of the invention may generally be prepared by one skilled in the art using at least the following methods. Unless otherwise stated, the groups of each of the compounds are as previously defined.

(105) With regard to the series A compounds as identified above, there are at least three general methods that may be employed, identified herein as general method A1, A2 and A3, respectively.

Example 2: Testing of the Compounds of the Invention Against RSV

(252) Cell Lines and Transfections

(253) Human carcinoma (HEp-2, ATCC CCL-23), human lung carcinoma (A549, ATCC CCL-185), human bronchial epithelial (BEAS-2B, ATCC CRL-9609), human embryonic kidney (293T, ATCC CRL-3216), and Madin Darby canine kidney (MDCK, ATCC CCL-34) cells were maintained at 37 C. and 5% CO2 in Dulbecco's modified Eagle's medium (DMEM) supplemented with 7.5% fetal bovine serum. Lipofectamine 2000 or GeneJuice were used for all transient transfection reactions.

(254) RSV Amplification and Virion Purification

(255) recRSV stocks were grown on HEp-2 cells inoculated at a multiplicity of infection (MOI) of 0.01 pfu/cell. Infected cells were kept for 16 hours at 37 C., followed by incubation at 32 C. for five to seven days. Cell-associated progeny virus was released through one freeze/thaw cycle and titers determined by TCID50 titration on HEp-2 cells. Two alternative strategies were explored to remove contaminating luciferase proteins from virus stocks. Progeny virions in culture supernatants (IAV stocks) or released through one freeze/thaw cycle from infected cells (RSV stocks) were cleared (4,000g for 20 minutes at 4 C.), then pelleted (60,000g for 30 minutes at 4 C.). Pelleted material was resuspended in TNE buffer (50 mM Tris/Cl pH 7.2, 10 mM EDTA) and purified through a 20/60% one-step sucrose gradient in TNE buffer (100,000g for 90 minutes at 4 C.). Virions were harvested from the gradient intersection.

(256) Automated HTS Protocol in 384-Well Plate Format

(257) BEAS-2B cells (810.sup.3/well) were injected in 30 l/well into barcoded white wall/clear bottom 384-well plates using a MultiFlo automated dispenser (BioTek) equipped with dual 10-l peristaltic pump manifolds, collected (150g for 90 seconds at 25 C.), and incubated for five hours at 37 C. and 5% CO.sub.2. Compound was added to a final concentration of 5 M (20 nl/well) using a high-density pin tool (V&P Scientific) attached to the pipetting head of Hamilton Nimbus liquid handler, followed by infection in 10 l/well using the MultiFlo dispenser unit, spin collection (150g for 90 seconds at 25 C.), and incubation for 40 hours at 37 C. and 5% CO.sub.2. Final vehicle (DMSO) concentration was 0.05%. Barcodes of source and assay plates were automatically detected and recorded by the Nimbus unit at the time of stamping. Using a stacker unit with integrated barcode reader (Biotek) attached to an H1 Biotek synergy plate reader, plates were automatically loaded, luciferase substrates (15 l/well) injected, and bioluminescence recorded after a three minute lag time. Readouts were automatically saved by plate barcode. For analysis of primary screen raw data, normalized relative inhibition values were calculated for each compound by subtracting each value from the average of the plate vehicle controls, followed by dividing the results by the difference between the means of plate vehicle and positive controls. Hits candidates were defined as compounds showing 75% inhibition of normalized signal intensity against either or both viral targets.

(258) Dose-Response Counterscreens

(259) Two-fold serial dilutions of hit candidates were prepared in 384-well plates in three replicates each using the Nimbus liquid handler. BEAS-2B cells (810.sup.3/well) were then plated as before, serial dilutions transferred using the pin-tool, and cells infected with recombinant virus strains expressing distinct luciferase reporter proteins or left uninfected for cell viability assessment. Reporter signals were recorded as outlined above. To determine cell viability, PrestoBlue substrate (life technologies) was added after 40-hour incubation of cells at 37 C. (5 l/well) and top-read fluorescence (excitation 560 nm; emission 590 nm; instrument gain 85) recorded after 45 minutes of incubation at 37 C. using the H1 synergy plate reader. Four-parameter variable slope regression modeling was applied to determine 50% active (EC.sub.50) and toxic (CC.sub.50) concentrations.

(260) RSV Minigenome Reporter Assays

(261) An RSV minigenome reporter plasmid (pHH-RSV-repI-firefly) was constructed under the control of the constitutive RNA pol I promoter by generating a firefly luciferase open reading frame flanked by the 5- and 3-non-coding regions and transfer into a pHH plasmid backbone harboring an RNA pol I promoter. Huh-7 cells were co-transfected with this plasmid and expression plasmids pRSV-L, pRSV-M2-1, pRSV-N and pRSV-P, which encode the RSV polymerase protein subunits. Test compounds were added in serial dilutions, luciferase reporter activities determined 40 hours post-transfection, and EC.sub.50 concentrations calculated if possible.

(262) Virus Yield Reduction Assay

(263) Hep2 cells were seeded in a 12-well plate format and exposed to serial dilutions of compound (3-fold, 20 M highest), followed by infection with recombinant RSV-A2 harboring the fusion protein of the L19F isolate at a multiplicity of infection (MOI) of 0.1. Cell-associated progeny virions were harvested after 48-hour incubation at 37 C. and subjected to TCID.sub.50 titration on Hep2 cells. Viral titers were calculated based on the Spearman Karber method and inhibitory concentrations based on virus yields determined through four-parameter variable slope regression modeling.

(264) Statistical Analysis

(265) The Excel and Prism 6 (GraphPad) software packages were used for data analysis.

(266) Statistical significance of differences between sample groups were assessed by unpaired two-tailed t tests or one-way analysis of variance (ANOVA) in combination with Tukey's multiple comparison post-tests, respectively.

(267) Assay results for two compounds: RSV-156784 and RSV-171352 are presented in FIGS. 1-4.
