The term “optionally substituted” in reference to a particular moiety of the compound described herein such as the compound of Formula A or Formula I (e.g., an optionally substituted aryl group) refers to a moiety wherein all substituents are hydrogen or wherein one or more of the hydrogens of the moiety may be replaced by the listed substituents.
Unless otherwise specified, the carbon atoms of the compounds of Formula and Formula I are intended to have a valence of four. If in some chemical structure representations, carbon atoms do not have a sufficient number of variables attached to produce a valence of four, the remaining carbon substituents needed to provide a valence of four should be assumed to be hydrogen.
Any reference to the compounds described herein also includes a reference to a pharmaceutically acceptable salt thereof. Examples of pharmaceutically acceptable salts of the compounds described herein include salts derived from an appropriate base, such as an alkali metal or an alkaline earth (for example, Na+, Li+, K+, Ca+2 and Mg+2), ammonium and NR4+ (wherein R is defined herein). Pharmaceutically acceptable salts of a nitrogen atom or an amino group include (a) acid addition salts formed with inorganic acids, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, sulfamic acids, phosphoric acid, nitric acid and the like; (b) salts formed with organic acids such as, for example, acetic acid, oxalic acid, tartaric acid, succinic acid, maleic acid, fumaric acid, gluconic acid, citric acid, malic acid, ascorbic acid, benzoic acid, isethionic acid, lactobionic acid, tannic acid, palmitic acid, alginic acid, polyglutamic acid, naphthalenesulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, benzenesulfonic acid, naphthalenedisulfonic acid, polygalacturonic acid, malonic acid, sulfosalicylic acid, glycolic acid, 2-hydroxy-3-naphthoate, pamoate, salicylic acid, stearic acid, phthalic acid, mandelic acid, lactic acid, ethanesulfonic acid, lysine, arginine, glutamic acid, glycine, serine, threonine, alanine, isoleucine, leucine and the like; and (c) salts formed from elemental anions for example, chlorine, bromine, and iodine.

For therapeutic use, salts of active ingredients of the compounds described herein will be pharmaceutically acceptable, i.e., they will be salts derived from a pharmaceutically acceptable acid or base. It is also to be understood that the compositions herein comprise compounds described herein in their un-ionized, as well as zwitterionic form, and combinations with stoichiometric amounts of water as in hydrates. It is to be noted that all enantiomers, diastereomers, racemic mixtures, tautomers, polymorphs, and pseudopolymorphs of compounds described herein (e.g., compounds within the scope of Formula A or Formula I) and pharmaceutically acceptable salts thereof are embraced by the present disclosure. All mixtures of such enantiomers and diastereomers are within the scope of the present disclosure.
The compounds described herein may have chiral centers, e.g., chiral carbon or phosphorus atoms. The compounds described herein thus include racemic mixtures of all stereoisomers, including enantiomers, diastereomers, and atropisomers. In addition, the compounds described herein include enriched or resolved optical isomers at any or all asymmetric, chiral atoms. In other words, the chiral centers apparent from the depictions are provided as the chiral isomers or racemic mixtures. Both racemic and diastereomeric mixtures, as well as the individual optical isomers isolated or synthesized, substantially free of their enantiomeric or diastereomeric partners, are all within the scope of the disclosure. The racemic mixtures are separated into their individual, substantially optically pure isomers through appropriate techniques such as, for example, the separation of diastereomeric salts formed with optically active adjuncts, e.g., acids or bases followed by conversion back to the optically active substances. In most instances, the desired optical isomer is synthesized by means of stereospecific reactions, beginning with the appropriate stereoisomer of the desired starting material.
Stereochemical definitions and conventions used herein generally follow S. P. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984) McGraw-Hill Book Company, New York; and Eliel, E. and Wilen, S., Stereochemistry of Organic Compounds (1994) John Wiley & Sons, Inc., New York. Many organic compounds exist in optically active forms, i.e., they have the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and l, D and L, or (+) and (−) are employed to designate the sign of rotation of plane-polarized light by the compound, with S, (−), or 1 meaning that the compound is levorotatory while a compound prefixed with R, (+), or d is dextrorotatory. For a given chemical structure, these stereoisomers are identical except that they are mirror images of one another. A specific stereoisomer may also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture or a racemate, which may occur where there has been no stereoselection or stereospecificity in a chemical reaction or process. The terms “racemic mixture” and “racemate” refer to an equimolar mixture of two enantiomeric species, devoid of optical activity.
The compounds described herein may also exist as tautomeric isomers in certain cases. Although only one delocalized resonance structure may be depicted, all such forms are contemplated within the scope of the invention. For example, ene-amine tautomers can exist for purine, pyrimidine, imidazole, guanidine, amidine, and tetrazole systems and all their possible tautomeric forms are within the scope of the invention.
Any formula or structure described herein, including Formula A and Formula I compounds, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to 2H (deuterium, D), 3H (tritium), 11C, 13C, 14C, 15N, 18F, 31P, 32P, 35S, 36Cl and 125I. Various isotopically labeled compounds of the present disclosure, for example those into which radioactive isotopes such as 3H, 13C and 14C are incorporated. Such isotopically labelled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.
The disclosure also includes compounds (e.g., compounds of Formula A or Formula I) in which from 1 to x hydrogens attached to a carbon atom is/are replaced by deuterium, in which x is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any compound described herein (e.g., compounds of Formula A or Formula I) when administered to a mammal, particularly a human. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism”, Trends Pharmacol. Sci. 5(12):524-527 (1984). In view of the present disclosure, such compounds are synthesized by means known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.
Deuterium labeled or substituted therapeutic compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life, reduced dosage requirements and/or an improvement in therapeutic index. An 18F labeled compound may be useful for PET or SPECT studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. It is understood that deuterium in this context is regarded as a substituent in the compounds described herein.
For example, in the deuterated compound of Formula A, one or more hydrogen atoms attached to one or more carbon atoms of Formula A are replaced by deuterium. In some embodiments of the deuterated compound of Formula A, one hydrogen atom attached to one carbon atom of Formula A is replaced by deuterium. In some embodiments of the deuterated compound of Formula A, two hydrogen atoms attached to one carbon atom of Formula A are replaced by deuterium. In some embodiments of the deuterated compound of Formula A, two or more hydrogen atoms attached to two carbon atoms of Formula A are replaced by deuterium.
The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.
Whenever a compound described herein is substituted with more than one of the same designated group, e.g., “R” or “R”, then it will be understood that the groups may be the same or different, i.e., each group is independently selected.
Wavy lines, , indicate the site of covalent bond attachments to the adjoining substructures, groups, moieties, or atoms.
The term “treating”, as used herein, unless otherwise indicated, means reversing, alleviating, or inhibiting the progress of the disorder or condition to which such term applies, or one or more symptoms of such disorder or condition. The term “treatment”, as used herein, refers to the act of treating, as “treating” is defined immediately above.
“Prevention” or “preventing” means any treatment of a disease or condition that causes the clinical symptoms of the disease or condition not to develop. The compounds and compositions described herein may, in some embodiments, be administered to a subject (including a human) who is at risk of having the disease or condition. As used herein, the terms “preventing” and “prevention” encompass the administration of a compound, composition, or pharmaceutically acceptable salt according to the embodiments described herein pre- or post-exposure of the individual to a virus, but before the appearance of symptoms of the viral infection, and/or prior to the detection of the virus in the blood. The terms also refer to prevention of the appearance of symptoms of the disease and/or to prevent the virus from reaching detectible levels in the blood. The terms include both pre-exposure prophylaxis (PrEP), as well as post-exposure prophylaxis (PEP) and event driven or “on demand” prophylaxis. The terms also refer to prevention of perinatal transmission of a virus from mother to baby, by administration to the mother before giving birth and to the child within the first days of life. The terms also refer to prevention of transmission of a virus through blood transfusion.
The term “therapeutically effective amount”, as used herein, is the amount of a compound described herein (e.g., a compound of Formula A or Formula I) present in a composition described herein that is needed to provide a desired level of drug in the secretions and tissues of the airways and lungs, or alternatively, in the bloodstream of a subject to be treated to give an anticipated physiological response or desired biological effect when such a composition is administered by the chosen route of administration. The precise amount will depend upon numerous factors, for example the particular compound described herein (e.g., the compound of Formula A or Formula I), the specific activity of the composition, the delivery device employed, the physical characteristics of the composition, its intended use, as well as patient considerations such as severity of the disease state, patient cooperation, etc., and can readily be determined by one skilled in the art based upon the information provided herein.
The term “prodrug,” as used herein, refers to a biologically inactive derivative of a drug that, upon administration to the patient, can be converted to a parent drug according to some chemical or enzymatic pathway. For example, when a prodrug of the compound of Formula A, or a pharmaceutically acceptable salt thereof, is administered, the prodrug, or the pharmaceutically acceptable salt thereof, can be converted to the compound of Formula A. In another example, when a prodrug of the deuterated compound of Formula A, or a pharmaceutically acceptable salt thereof, is administered, the prodrug, or the pharmaceutically acceptable salt thereof, can be converted to the deuterated compound of Formula A.
The term “converted substantially,” as used herein in reference to a prodrug, refers to conversion of greater than 50% of a prodrug (e.g., a prodrug of the compound of Formula A, or a prodrug of the deuterated compound of Formula A) to a parent compound (e.g., the compound of Formula A, or the deuterated compound of Formula A). For example, the term “converted substantially” can refer to conversion of greater than 50%, greater than 60%, greater than 70%, greater than 80%, greater than 90%, greater than 95%, or greater than 99% of the prodrug of the compound of Formula A, the prodrug of the deuterated compound of Formula A, or the pharmaceutically acceptable salt thereof, to the compound of Formula A or the deuterated compound of Formula A.
The term “symptom” as used herein, can include symptoms of viral infections including, for example, fever, chills, cough, shortness of breath, fatigue, myalgias, headache, diarrhea, loss of taste, loss of smell, sore throat, congestion, nausea, and vomiting.

The compounds described herein may be formulated with conventional carriers and excipients. For example, tablets will contain excipients, glidants, fillers, binders and the like. Aqueous formulations are prepared in sterile form, and when intended for delivery by other than oral administration generally will be isotonic. All formulations may optionally comprise excipients such as those set forth in the “Handbook of Pharmaceutical Excipients” (1986). Pharmaceutically acceptable excipients include ascorbic acid and other antioxidants, chelating agents such as EDTA, carbohydrates such as dextran, hydroxyalkylcellulose, hydroxyalkylmethylcellulose, stearic acid and the like. In some embodiments, the formulations comprise one or more pharmaceutically acceptable excipients. The pH of the formulations ranges from about 3 to about 11, but is ordinarily about 7 to 10. In some embodiments, the pH of the formulations ranges from about 2 to about 5, but is ordinarily about 3 to 4.
While it is possible for the compounds of the disclosure (“the active ingredients”) to be administered alone it may be preferable to present them as pharmaceutical formulations. The formulations, both for veterinary and for human use, of the invention comprise at least one active ingredient, as above defined, together with one or more acceptable carriers therefor and optionally other therapeutic ingredients, particularly those additional therapeutic ingredients as discussed herein. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and physiologically innocuous to the recipient thereof.
The formulations include those suitable for the foregoing administration routes. The formulations may conveniently be presented in unit dosage form and may be prepared by any appropriate method known in the art of pharmacy. Techniques and formulations generally are found in Remington's Pharmaceutical Sciences (Mack Publishing Co., Easton, PA). Such methods include the step of bringing into association the active ingredient with the carrier which constitutes one or more accessory ingredients. In general, the formulations are prepared by uniformly and intimately bringing into association the active ingredient with liquid carriers or finely divided solid carriers or both, and then, if necessary, shaping the product.
In some embodiments, the pharmaceutical formulation is for subcutaneous, intramuscular, intravenous, oral, or inhalation administration.
In some embodiments, the compound described herein e.g., the compound of Formula A, the deuterated compound of Formula A, the prodrug of the compound of Formula A, the prodrug of the deuterated compound of Formula A, the compound of Formula I, the deuterated compound of Formula I, or the pharmaceutically acceptable salt thereof, described herein have optimized/improved pharmacokinetic properties and are amenable to oral administration. For example, the compounds of Formula I have improved bioavailability and can therefore be administered by oral administration.
In some embodiments, the formulations of the present invention are suitable for oral administration may be presented as discrete units such as capsules, cachets or tablets each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or a suspension in an aqueous or non-aqueous liquid; or as an oil-in-water liquid emulsion or a water-in-oil liquid emulsion. The active ingredient may also be administered as a bolus, electuary or paste.
In some embodiments, the tablet is made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing in a suitable machine the active ingredient in a free-flowing form such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, preservative, surface active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of the powdered active ingredient moistened with an inert liquid diluent. The tablets may optionally be coated or scored and optionally are formulated so as to provide slow or controlled release of the active ingredient therefrom.
For infections of the eye or other external tissues, e.g., mouth and skin, the formulations are applied as a topical ointment or cream containing the active ingredient(s) in an amount of, for example, 0.075 to 20% w/w (including active ingredient(s) in a range between 0.1% and 20% in increments of 0.1% w/w such as 0.6% w/w, 0.7% w/w, etc.), preferably 0.2 to 15% w/w and most preferably 0.5 to 10% w/w. When formulated in an ointment, the active ingredients may be employed with either a paraffinic or a water-miscible ointment base. Alternatively, the active ingredients may be formulated in a cream with an oil-in-water cream base.
If desired, the aqueous phase of the cream base may include, for example, at least 30% w/w of a polyhydric alcohol, i.e., an alcohol having two or more hydroxyl groups such as propylene glycol, butane 1,3-diol, mannitol, sorbitol, glycerol and polyethylene glycol (including PEG 400) and mixtures thereof. The topical formulations may desirably include a compound which enhances absorption or penetration of the active ingredient through the skin or other affected areas. Examples of such dermal penetration enhancers include dimethyl sulphoxide and related analogs.
The oily phase of the emulsions of this invention may be constituted from known ingredients in a known manner. While the phase may comprise merely an emulsifier (otherwise known as an emulgent), it desirably comprises a mixture of at least one emulsifier with a fat or an oil or with both a fat and an oil. Preferably, a hydrophilic emulsifier is included together with a lipophilic emulsifier which acts as a stabilizer. It is also preferred to include both an oil and a fat. Together, the emulsifier(s) with or without stabilizer(s) make up the so-called emulsifying wax, and the wax together with the oil and fat make up the so-called emulsifying ointment base which forms the oily dispersed phase of the cream formulations.
Emulgents and emulsion stabilizers suitable for use in the formulation of the invention include Tween® 60, Span® 80, cetostearyl alcohol, benzyl alcohol, myristyl alcohol, glyceryl mono-stearate and sodium lauryl sulfate. Further emulgents and emulsion stabilizers suitable for use in the formulation of the invention include Tween® 80.
The choice of suitable oils or fats for the formulation is based on achieving the desired cosmetic properties. The cream should preferably be a non-greasy, non-staining and washable product with suitable consistency to avoid leakage from tubes or other containers. Straight or branched chain, mono- or dibasic alkyl esters such as di-isoadipate, isocetyl stearate, propylene glycol diester of coconut fatty acids, isopropyl myristate, decyl oleate, isopropyl palmitate, butyl stearate, 2-ethylhexyl palmitate or a blend of branched chain esters known as Crodamol CAP may be used, the last three being preferred esters. These may be used alone or in combination depending on the properties required. Alternatively, high melting point lipids such as white soft paraffin and/or liquid paraffin or other mineral oils are used.
Pharmaceutical formulations according to the present invention comprise a compound according to the invention together with one or more pharmaceutically acceptable carriers or excipients and optionally other therapeutic agents. Pharmaceutical formulations containing the active ingredient may be in any form suitable for the intended method of administration. When used for oral use for example, tablets, troches, lozenges, aqueous or oil suspensions, dispersible powders or granules, emulsions, hard or soft capsules, syrups or elixirs may be prepared. Compositions intended for oral use may be prepared according to any method known to the art for the manufacture of pharmaceutical compositions and such compositions may contain one or more agents including sweetening agents, flavoring agents, coloring agents and preserving agents, in order to provide a palatable preparation. Tablets containing the active ingredient in admixture with non-toxic pharmaceutically acceptable excipient which are suitable for manufacture of tablets are acceptable. These excipients may be, for example, inert diluents, such as calcium or sodium carbonate, lactose, calcium or sodium phosphate; granulating and disintegrating agents, such as maize starch, or alginic acid; binding agents, such as starch, gelatin or acacia; and lubricating agents, such as magnesium stearate, stearic acid or talc. Tablets may be uncoated or may be coated by known techniques including microencapsulation to delay disintegration and adsorption in the gastrointestinal tract and thereby provide a sustained action over a longer period. For example, a time delay material such as glyceryl monostearate or glyceryl distearate alone or with a wax may be employed.
Formulations for oral use may be also presented as hard gelatin capsules where the active ingredient is mixed with an inert solid diluent, for example calcium phosphate or kaolin, or as soft gelatin capsules wherein the active ingredient is mixed with water or an oil medium, such as peanut oil, liquid paraffin or olive oil.
Aqueous suspensions of the invention contain the active materials in admixture with excipients suitable for the manufacture of aqueous suspensions. Such excipients include a suspending agent, such as sodium carboxymethylcellulose, methylcellulose, hydroxypropyl methylcelluose, sodium alginate, polyvinylpyrrolidone, gum tragacanth and gum acacia, and dispersing or wetting agents such as a naturally-occurring phosphatide (e.g., lecithin), a condensation product of an alkylene oxide with a fatty acid (e.g., polyoxyethylene stearate), a condensation product of ethylene oxide with a long chain aliphatic alcohol (e.g., heptadecaethyleneoxycetanol), a condensation product of ethylene oxide with a partial ester derived from a fatty acid and a hexitol anhydride (e.g., polyoxyethylene sorbitan monooleate). The aqueous suspension may also contain one or more preservatives such as ethyl or n-propyl p-hydroxy-benzoate, one or more coloring agents, one or more flavoring agents and one or more sweetening agents, such as sucrose or saccharin.

It is also possible to combine any compound of the invention with one or more additional active therapeutic agents in a unitary dosage form for simultaneous or sequential administration to a patient. The combination therapy may be administered as a simultaneous or sequential regimen. When administered sequentially, the combination may be administered in two or more administrations.
Co-administration of a compound of the invention with one or more other active therapeutic agents generally refers to simultaneous or sequential administration of a compound of the invention and one or more other active therapeutic agents, such that therapeutically effective amounts of the compound of the invention and one or more other active therapeutic agents are both present in the body of the patient.
Co-administration includes administration of unit dosages of the compounds described herein before or after administration of unit dosages of one or more other active therapeutic agents, for example, administration of the compounds described herein within seconds, minutes, or hours of the administration of one or more other active therapeutic agents. For example, a unit dose of a compound of the invention can be administered first, followed within seconds or minutes by administration of a unit dose of one or more other active therapeutic agents. Alternatively, a unit dose of one or more other therapeutic agents can be administered first, followed by administration of a unit dose of a compound of the invention within seconds or minutes. In some cases, it may be desirable to administer a unit dose of a compound of the invention first, followed, after a period of hours (e.g., 1-12 hours), by administration of a unit dose of one or more other active therapeutic agents. In other cases, it may be desirable to administer a unit dose of one or more other active therapeutic agents first, followed, after a period of hours (e.g., 1-12 hours), by administration of a unit dose of a compound of the invention.
The combination therapy may provide “synergy” and “synergistic”, i.e., the effect achieved when the active ingredients used together is greater than the sum of the effects that results from using the compounds separately. A synergistic effect may be attained when the active ingredients are: (1) co-formulated and administered or delivered simultaneously in a combined formulation; (2) delivered by alternation or in parallel as separate formulations; or (3) by some other regimen. When delivered in alternation therapy, a synergistic effect may be attained when the compounds are administered or delivered sequentially, e.g., in separate tablets, pills or capsules, or by different injections in separate syringes. In general, during alternation therapy, an effective dosage of each active ingredient is administered sequentially, i.e., serially, whereas in combination therapy, effective dosages of two or more active ingredients are administered together. A synergistic anti-viral effect denotes an antiviral effect, which is greater than the predicted purely additive effects of the individual compounds of the combination.
The compounds described herein are also used in combination with other active therapeutic agents. For the treatment of Pneumoviridae virus infections, preferably, the other active therapeutic agent is active against Pneumoviridae virus infections, particularly respiratory syncytial virus infections and/or metapneumovirus infections. Non-limiting examples of these other active therapeutic agents active against RSV are ribavirin, palivizumab, motavizumab, RSV-IGIV (RespiGam®), MEDI-557, A-60444 (also known as RSV604), MDT-637, BMS-433771, ALN-RSVO, ALX-0171 and mixtures thereof. Other non-limiting examples of other active therapeutic agents active against respiratory syncytial virus infections include respiratory syncytial virus protein F inhibitors, such as AK-0529; RV-521, ALX-0171, JNJ-53718678, BTA-585, and presatovir; RNA polymerase inhibitors, such as lumicitabine and ALS-8112; anti-RSV G protein antibodies, such as anti-G-protein mAb; viral replication inhibitors, such as nitazoxanide.
In some embodiments, the other active therapeutic agent may be a vaccine for the treatment or prevention of RSV, including but not limited to MVA-BN RSV, RSV-F, MEDI-8897, JNJ-64400141, DPX-RSV, SynGEM, GSK-3389245A, GSK-300389-1A, RSV-MEDI deltaM2-2 vaccine, VRC-RSVRGPO84-00VP, Ad35-RSV-FA2, Ad26-RSV-FA2, and RSV fusion glycoprotein subunit vaccine.

In some embodiments, the other active therapeutic agent may be a vaccine for the treatment or prevention of metapneumovirus infections, including but not limited to mRNA-1653 and rHMPV-Pa vaccine.
The compounds described herein are also used in combination with other active therapeutic agents. For the treatment ofpicornaviridae virus infections, preferably, the other active therapeutic agent is active against picornaviridae virus infections, particularly Enterovirus infections. Non-limiting examples of these other active therapeutic agents are capsid binding inhibitors such as pleconaril, BTA-798 (vapendavir) and other compounds disclosed by Wu, et al. (U.S. Pat. No. 7,078,403) and Watson (U.S. Pat. No. 7,166,604); fusion sialidase protein such as DAS-181; a capsid protein VP1 inhibitor such as VVX-003 and AZN-001; a viral protease inhibitor such as CW-33; a phosphatidylinositol 4 kinase beta inhibitor such as GSK-480 and GSK-533; anti-EV71 antibody.
In some embodiments, the other active therapeutic agent may be a vaccine for the treatment or prevention ofpicornaviridae virus infections, including but not limited to EV71 vaccines, TAK-021, and EV-D68 adenovector-based vaccine.
Many of the infections of the pneumoviridae, picornaviridae, and coronaviridae viruses are respiratory infections. Therefore, additional active therapeutics used to treat respiratory symptoms and sequelae of infection may be used in combination with the compounds described herein. The additional agents are preferably administered orally or by direct inhalation. For example, other preferred additional therapeutic agents in combination with the compounds described herein for the treatment of viral respiratory infections include, but are not limited to, bronchodilators and corticosteroids.
Glucocorticoids, which were first introduced as an asthma therapy in 1950 (Carryer, Journal of Allergy, 21, 282-287, 1950), remain the most potent and consistently effective therapy for this disease, although their mechanism of action is not yet fully understood (Morris, J. Allergy Clin. Immunol., 75 (1 Pt) 1-13, 1985). Unfortunately, oral glucocorticoid therapies are associated with profound undesirable side effects such as truncal obesity, hypertension, glaucoma, glucose intolerance, acceleration of cataract formation, bone mineral loss, and psychological effects, all of which limit their use as long-term therapeutic agents (Goodman and Gilman, 10th edition, 2001). A solution to systemic side effects is to deliver steroid drugs directly to the site of inflammation. Inhaled corticosteroids (ICS) have been developed to mitigate the severe adverse effects of oral steroids. Non-limiting examples of corticosteroids that may be used in combinations with the compounds described herein are dexamethasone, dexamethasone sodium phosphate, fluorometholone, fluorometholone acetate, loteprednol, loteprednol etabonate, hydrocortisone, prednisolone, fludrocortisones, triamcinolone, triamcinolone acetonide, betamethasone, beclomethasone diproprionate, methylprednisolone, fluocinolone, fluocinolone acetonide, flunisolide, fluocortin-21-butylate, flumethasone, flumetasone pivalate, budesonide, halobetasol propionate, mometasone furoate, fluticasone, AZD-7594, ciclesonide; or a pharmaceutically acceptable salts thereof.
Other anti-inflammatory agents working through anti-inflammatory cascade mechanisms are also useful as additional therapeutic agents in combination with the compounds described herein for the treatment of viral respiratory infections. Applying “anti-inflammatory signal transduction modulators” (referred to in this text as AIS™), like phosphodiesterase inhibitors (e.g., PDE-4, PDE-5, or PDE-7 specific), transcription factor inhibitors (e.g., blocking NFκB through TKK inhibition), or kinase inhibitors (e.g., blocking P38 MAP, INK, PI3K, EGFR or Syk) is a logical approach to switching off inflammation as these small molecules target a limited number of common intracellular pathways—those signal transduction pathways that are critical points for the anti-inflammatory therapeutic intervention (see review by P. J. Barnes, 2006). These non-limiting additional therapeutic agents include: 5-(2,4-Difluoro-phenoxy)-1-isobutyl-1H-indazole-6-carboxylic acid (2-dimethylamino-ethyl)-amide (P38 Map kinase inhibitor ARRY-797); 3-Cyclopropylmethoxy-N-(3,5-dichloro-pyridin-4-yl)-4-difluorormethoxy-benzamide (PDE-4 inhibitor Roflumilast); 4-[2-(3-cyclopentyloxy-4-methoxyphenyl)-2-phenyl-ethyl]-pyridine (PDE-4 inhibitor CDP-840); N-(3,5-dichloro-4-pyridinyl)-4-(difluoromethoxy)-8-[(methylsulfonyl)amino]-1-dibenzofurancarboxamide (PDE-4 inhibitor Oglemilast); N-(3,5-Dichloro-pyridin-4-yl)-2-[1-(4-fluorobenzyl)-5-hydroxy-1H-indol-3-yl]-2-oxo-acetamide (PDE-4 inhibitor AWD 12-281); 8-Methoxy-2-trifluoromethyl-quinoline-5-carboxylic acid (3,5-dichloro-1-oxy-pyridin-4-yl)-amide (PDE-4 inhibitor Sch 351591); 4-[5-(4-Fluorophenyl)-2-(4-methanesulfinyl-phenyl)-1H-imidazol-4-yl]-pyridine (P38 inhibitor SB-203850); 4-[4-(4-Fluoro-phenyl)-1-(3-phenyl-propyl)-5-pyridin-4-yl-1H-imidazol-2-yl]-but-3-yn-1-ol (P38 inhibitor RWJ-67657); 4-Cyano-4-(3-cyclopentyloxy-4-methoxy-phenyl)-cyclohexanecarboxylic acid 2-diethylamino-ethyl ester (2-diethyl-ethyl ester prodrug of Cilomilast, PDE-4 inhibitor); (3-Chloro-4-fluorophenyl)-[7-methoxy-6-(3-morpholin-4-yl-propoxy)-quinazolin-4-yl]-amine (Gefitinib, EGFR inhibitor); and 4-(4-Methyl-piperazin-1-ylmethyl)-N-[4-methyl-3-(4-pyridin-3-yl-pyrimidin-2-ylamino)-phenyl]-benzamide (Imatinib, EGFR inhibitor).
Combinations comprising inhaled β2-adrenoreceptor agonist bronchodilators such as formoterol, albuterol or salmeterol with the compounds described herein are also suitable, but non-limiting, combinations useful for the treatment of respiratory viral infections.

The effects of compound 16 on pregnant Wistar Han rats and development of the embryo consequent to exposure of the female from implantation to closure of the hard palate were evaluated. Compound 16 was administered to 4 groups of presumed pregnant rats (8/group) at doses of 0 (vehicle), 125, 250, and 500 mg/kg/day via once daily gavage administration during organogenesis (gestation days [GD] 6 to 17) at a dose volume of 5 mL/kg. Additional pregnant rats were similarly dosed for toxicokinetic assessment of compound 16 and compound 1. Assessment of toxicity to the pregnant rats was based on mortality, clinical observations, body weights and food consumption. Rats were necropsied and cesarean sectioned on GD 21. An examination of the external features of the carcass; external body orifices; abdominal, thoracic, pelvic, and oral cavities; organs; and tissues was performed. Any macroscopic abnormalities were noted. Pregnancy status was determined. The uterus from each pregnant animal was excised, weighed, and examined for the number and placement of live and dead fetuses, the number of early or late resorptions, and any abnormalities. The right and left ovaries from each pregnant female were examined for the number of corpora lutea. Each fetus was sexed, weighed, and examined for external abnormalities. Each fetus had their heads removed, stored frozen on dry ice, and cross-sectioned using the Wilson's sectioning technique (Astroff et al., 2002). Internal organs of the thoracic and abdominal cavities were examined in the fresh state using modified Staples' technique (Stuckhardt and Poppe, 1984). Fetal findings were classified as variations or malformations.
The dose level of 500 mg/kg/day was not tolerated and the toxicity dose group was terminated early by Gestation Day (GD) 16. Mortality, severe clinical signs, and macroscopic observations at necropsy of enlarged and discolored kidneys, and enlarged and discolored adrenal glands were expected findings as they had already been observed in previous toxicology studies in female rats. Due to excessive maternal toxicity, fetal parameters were not evaluated for this group.
There were no remarkable clinical signs or effects on body weight, food consumption or macroscopic observations at 125 or 250 mg/kg/day. No compound 16-related effects were observed for embryo-fetal viability parameters, litter and fetal weights, or fetal pathology at 125 or 250 mg/kg/day. The no-observed-adverse-effect level (NOAEL) for maternal toxicity and embryofetal development was 250 mg/kg/day, associated with compound 1 AUC0-24h exposures of 183,000 ng*h/mL on GD 17.
The potential of compound 16 to induce developmental toxicity after maternal exposure during the critical period of organogenesis (GD 6 through 17) were evaluated, maternal toxicity at the exposure levels tested was characterized, and a no observed-adverse-effect level (NOAEL) for maternal toxicity and developmental toxicity following oral administration in Wistar Han rats was determined.
Compound 16 was administered to 3 groups of presumed pregnant rats (25/group) at doses of 0 (vehicle), 125 and 250 mg/kg/day via once daily gavage administration during organogenesis (gestation days [GD] 6 to 17) at a dose volume of 5 mL/kg. Assessment of toxicity to the pregnant rats was based on mortality, clinical observations, body weights and food consumption. Rats were necropsied and cesarean sectioned on GD 21. An examination of the external features of the carcass; external body orifices; abdominal, thoracic, pelvic, and oral cavities; organs; and tissues was performed. Any macroscopic abnormalities were noted. Pregnancy status was determined. The uterus from each pregnant animal was excised, weighed, and examined for the number and placement of live and dead fetuses, the number of early or late resorptions, and any abnormalities. The right and left ovaries from each pregnant female were examined for the number of corpora lutea. Each fetus was sexed, weighed, and examined for external abnormalities Approximately one-half of the fetuses in each litter were examined for visceral anomalies by dissection in the fresh state. The thoracic and abdominal cavities were opened and dissected using a technique described by Stuckhardt and Poppe (1984). Fetal kidneys were examined and graded for renal papillae development (Woo and Hoar, 1972). The heads from these fetuses were removed and placed in Harrison's fixative for soft tissue examination using the Wilson sectioning technique (Wilson, 1965). The remaining fetuses (approximately one-half from each litter), were eviscerated, fixed in 100% ethyl alcohol, macerated in potassium hydroxide and stained with Alizarin Red S by a method similar to that described by Dawson (1926) for subsequent examination of skeletons.
No compound 16-related effects on intrauterine growth or survival were noted. No compound 16-related external, visceral or skeletal malformations or variations were noted. The no-observed-adverse-effect level (NOAEL) for maternal toxicity and embryofetal development was 250 mg/kg/day.
The effects of compound 16 on pregnant New Zealand White (NZW) rabbits and the development of the embryo consequent to exposure of the female from implantation to closure of the hard palate (Gestation Days [GD] 7 through 19) was evaluated. Compound 16 was administered to 4 groups of pregnant rabbits (20/group) at doses of 0 (0.5% methylcellulose in deionized water), 125, 250, and 500 mg/kg/day once daily via oral gavage during organogenesis (GD 7 to 19). Assessment of toxicity was based on mortality, clinical observations, body weights, food consumption, and necropsy and cesarean section findings. In addition, blood samples were collected for toxicokinetic evaluation of compound 16 and compound 1 from similarly dosed animals (4/group). Due to excessive maternal toxicity observed at 500 mg/kg/day, the toxicity dose group was terminated early between GD 17 and 22, and fetal parameters were not evaluated for this group.
Reduced food consumption compared to control was noted for animals administered 250 or 500 mg/kg/day, with a decrease in mean maternal weight gain relative to control in animals administered 250 mg/kg/day, and mean body weight loss relative to GD 7 weight in animals administered 500 mg/kg/day. An increase in the rate of post-implantation loss was noted in animals administered 250 mg/kg/day. Increased rates of post implantation loss for animals administered 250 mg/kg/day correlated with an increase in the mean number of early resorptions and a reduction in the mean number of live fetuses. Fetuses from animals administered 250 mg/kg/day were noted with increased rates of ventricular septum defects, large or small heart ventricles, dilated or malpositioned aortas, retroesophageal aortic arches, retroesophageal subclavian arteries, abnormal lobulation of the liver. No compound 16-related skeletal malformations were noted. Based on these findings, the NOAEL of compound 16 for embryo-fetal development in rabbits was 125 mg/kg/day associated with compound 1 AUC0-24h exposures of 64,100 ng*h/mL on GD 17.
Materials and Methods
Compounds
All compounds were synthesized by known methods or purchased. Validation of chemical identities were determined by NMR and LCMS, and purity>95% was assessed by HPLC. Compounds were solubilized in 100% dimethyl sulfoxide (DMSO) at a concentration of 10 mM.
Cells
A549-hACE2 cells that stably express human angiotensin converting enzyme 2 (hACE2) were established and provided by the University of Texas Medical Branch (Mossel, E C 2005). A549-hACE2 cells were maintained at 37° C. and 5% CO2 in Dulbecco's Minimum Essential Medium (DMEM) with GlutaMAX (Gibco cat #10569-010) supplemented with 10% heat-inactivated fetal bovine serum (FBS) (Hyclone Cat #SH30396.03), 100 units/mL penicillin, 100 μg/mL streptomycin (Gibco Cat #15140-122), and the selection agent—10 μg/mL Blasticidin. A549-hACE2 cells used in all experimental set-ups were between passage 5 and 30.
Virus Propagation
Recombinant firefly luciferase WA SARS-CoV-2 virus (SARS-CoV-2 Fluc) was amplified from a stock obtained from University of Texas Medical Branch (UTMB; Galveston, TX) generated as described previously (Xie, X., et al. (2021). “Engineering SARS-CoV-2 using a reverse genetic system.” Nat Protoc 16(3): 1761-1784). SARS-CoV-2 Fluc was propagated as high titer stocks in Vero-TMPRSS2 cells as follows: 1×107 Vero-TMPRSS2 cells were seeded into a T225 flask in Vero-TMPRSS2 maintenance media and incubated overnight at 37° C.+5% CO2. The following day the media was aspirated and replaced with 25 mL of DMEM supplemented with 2% FBS (infection medium) and infected with 10 μL of a P0 SARS-CoV-2 Fluc stock. The flasks were returned to 37° C.+5% CO2 until only 10-20% of viable cells remained (typically 36-72 hours post infection (hpi)). The supernatant was harvested into a 50 mL falcon tube and centrifuged at 2000×g for 5 minutes to pellet cellular debris. The clarified supernatant was then aliquoted as a working P1 stock into 250 μL aliquots and frozen at −80° C. The titer of the working P1 stock was determined by plaque formation assay (PFA).
SARS-CoV-2 Fluc Antiviral Assay
A549-hACE2 cells were plated at 12,000 cells per well, in 96-well plates, in 100 μL volume of maintenance media and incubated overnight at 37° C. with 5% CO2. The following day spent media was aspirated and 100 μL of infection media (DMEM supplemented with 2% FBS) was added to each well. Compounds were added directly to cultures using a HP D300e digital liquid dispenser, with DMSO volumes normalized to that of the highest compound concentration (final DMSO concentration<0.1%). Plates (in quadruplicate for each combination) were laid out in an array with increasing concentrations across rows and columns of the two drugs being assessed and compound dilution placement was then randomized on each plate to reduce variability from edge effect. Compound 16, Compound 1, and molnupiravir were dispensed into plates at starting concentrations of 4000, 5000, and 10,000 nM, respectively and titrated by with a pre-determined optimal serial dilution for each compound. Nirmatrelvir was dispensed into plates at a starting concentration or 600 nM and serially diluted 1:2. For the 3-drug combinations, compounds were dispensed as described above, but ritonavir was dispensed at either 0, 300, 600, 1200, or 2400 nM for the entirety of individual plates, in addition to 2 other compounds being assessed (Compound 16 and nirmatrelvir or Compound 1 and nirmatrelvir). 50 μL of recombinant WA SARS-CoV-2 Fluc was added at a MOI of 1 and for uninfected control wells, 50 μL of infection media was added to one column and cultures were incubated at 37° C. with 5% CO2. At 24 hpi, cultures were removed from the incubator, and 50 μL of Promega One-Glo Luciferase Assay System (CAT #E6120) was added to all wells. Plates were put on the orbital shaker for 10 minutes and read for luminescence on the Perkin Elmer Envision plate reader.
Synergy Finder 3.0 Analysis
After de-randomizing the raw luminescence data from the Envision plate reader in Microsoft Excel, dose-dependent percent inhibition of WA SARS-CoV-2 Fluc was calculated (% inhibition=100×(1−(X−min)/(max−min)), and the data matrices were uploaded into Synergy Finder (version 3.0) (https://synergyfinder.fimm.fi) analytic software {Ianevski, A 2022 #67038}. The drug combination effects were quantified using Bliss independence (background corrected) mathematical models. Synergy reports were generated for each drug combination, and scores are reported as median values of all four biological replicates using the conventional Synergy scoring methodology. The methodology defines a synergy score between −10 and 10 as being additive, below −10 is considered antagonistic, and above 10 is considered synergistic {Ianevski, A 2022 #67038}.
Results
Bliss independence consensus scores were used to evaluate the drug combinations below by interpreting any score between −10 and 10 as additive, greater than 10 are synergistic, and below 10 are antagonistic. The Bliss consensus score summary for 2-drug combinations is reported in Table 4.1 and Table 4.2. For 2-drug combinations of Compound 1 and nirmatrelvir, it was observed that an additive effect with an average Bliss score of 0.96±0.67 for four replicates (representative Bliss independence plots are presented in
The 3-drug combination Bliss consensus scores are summarized in Table 4.3 and Table 4.4. For the 3-drug combinations of Compound 1, nirmatrelvir, and ritonavir, additive effects are observed with an average Bliss score of 2.80±3.95.
Drug combinations of Compound 1 or Compound 16 with either molnupiravir, nirmatrelvir, and/or ritonavir all demonstrate additive effects against SARS-CoV-2 in A549-hACE-2 cells.

Materials and Methods
Cell Culture
Non-infectious BHK-SARS-2R_GFP_NeoR_NL (SCL414) replicon cell lines were licensed from Emory University (Lan et al 2021). These are stable cell lines expressing SARS-CoV-2 replicon DNA and sNLuc reporter gene. Cells were maintained in Dulbecco's Modified Eagle's Medium (ThermoFisher, Catalog #10566016) supplemented with 10% fetal bovine serum ((ThermoFisher, Catalog #SH3040602HI), 100 U/mL penicillin/100 μg/mL streptomycin ((ThermoFisher, Catalog #15140122) and 1 mg/mL Geneticine™ ((ThermoFisher, Catalog #10131027).
Drug-Combination Assay
BHK-SARS-2R_GFP_NeoR_NL replicon cell line 50 μL of the assay media (DMEM supplemented with 10% FBS) was added to white clear bottom 96-well plates (ThermoFisher, Catalog #07-200-566). Serial dilutions of Compound 1 and nirmatrelvir were added in a matrix format to the wells with assay media using the HP D300e digital dispenser with normalization to the highest concentration of DMSO (ATCC 4-X™) in all wells (>0.1% final volume). Starting concentration for Compound 1 was 12 μM and for nirmatrelvir was 1.2 μM. For negative control, puromycin dissolved in DMSO was added at a final concentration of 10 μM. Untreated wells were used as a positive control. For this assay the drug combination matrix of Compound 1 with nirmatrelvir along with nirmatrelvir and Compound 1 self-matrix (internal control) was tested. Cells were then seeded in the same plate at a density of 8.0×104 cells/mL for a total volume of 100 μL/well and incubated for three days at 37° C. with 5% CO2. 50 μL/well of room temperature Nano-Glo® luciferase reagent (Promega, Catalog #N1110) was added to the plate. The plates were incubated for 1-2 mins on a shaker at room temperature and luminescence was measured using an Envision plate reader (PerkinElmer, Catalog #2105-0010). Each combination was performed in replicates of three. Average of the three replicates was used for analysis. Drug-response data were normalized to positive and negative control to determine percent inhibition.
