FIELD OF THE INVENTION

The present invention relates to macrocyclic compounds, in particular macrocyclic pyridotriazine derivatives and the prodrugs thereof, to methods to prevent or treat influenza viral infections by using said compounds and to said compounds for use as a medicine, more preferably for use as a medicine to treat or prevent influenza viral infections. The present invention also relates to pharmaceutical compositions or combination preparations of the compounds, to the compositions or preparations for use as a medicine, more preferably for the prevention or treatment of influenza viral infections.

BACKGROUND OF THE INVENTION

Influenza is a serious public health problem with high incidence in the human population resulting in regular large-scale morbidity and mortality. According to the WHO the average global burden of annual epidemics may be on the order of 1 billion cases, 3-5 million cases of severe illness and 300,000-500,000 deaths annually. In the US, annual influenza epidemics lead to approximately 30 million outpatient visits, resulting in medical costs of $10 billion annually. Lost earnings due to illness and loss of life represent a cost of over $15 billion annually and the total US economic burden of annual influenza epidemics amounts to over $85 billion.

Pathogens that cause influenza are negative sense, single-stranded RNA viruses, which belong to the family of Orthomyxoviridae. There are three types of influenza viruses: A, B and C. Influenza A viruses are the most common form, which can spread in mammals and birds. The subtypes of influenza A are named by the types of surface proteins hemagglutinin (H) and neuraminidase (N). There are 18 different hemagglutinin and 11 known neuraminidases. Current seasonal influenza viruses found in human are mainly H1N1 and H3N2 subtypes. Influenza B viruses are usually found only in humans. They are not divided into subtypes, but can be further broken down into different strains. Circulating influenza viruses are highly variable each year, and both influenza A and B cause seasonal epidemics all over the world. Influenza C viruses give much milder symptoms, which do not cause epidemics.

All three types of viruses have similar genome structures. The genome comprises 8 segments, encoding 9-11 proteins, depending on the type. Influenza A encodes 11 proteins, which includes the surface proteins (hemagglutinin (HA) and Neuraminidase (NA), the polymerase complex, nucleoprotein (NP), membrane proteins (M1 and M2), and other proteins (NS1, NS2, NEP). The polymerase complex is a heterotrimer composed of three subunits: polymerase acid (PA), polymerase basic 1 (PB1) and polymerase basic 2 (PB2). This polymerase is responsible for replication and transcription of the viral RNA in the nuclei of infected cells. The PA subunit contains the endonuclease active site. The endonuclease activity of the PA cleaves the cellular mRNA. which is then used by the PB1 subunit as a primer for the viral mRNA synthesis.

The most effective way to prevent the disease and/or severe outcomes from the illness is vaccination. However, vaccination comes with several limitations. First, influenza vaccine may be less effective in preventing illness among the elderly, and may only reduce severity of disease and incidence of complications and deaths. In addition, influenza vaccination is most effective when circulating viruses are well-matched with vaccine viruses, and the success of vaccination is largely dependent on the good prediction of the most prevalent virus type of the season. Rapid and continual evolution of influenza viral strains through antigenic drift, coupled with the short-lived nature of vaccine-induced immune responses to current influenza vaccines, means that vaccination with seasonally appropriate strains is required every year for prevention.

The current treatment of influenza uses either direct antiviral drugs, or medicines that reduce influenza-induced symptoms. There are two classes of influenza antiviral drugs available on the market: neuraminidase inhibitors and M2 channel inhibitors. Neuraminidase inhibitors oseltamivir or zanamivir are the primary antiviral agents recommended for the prevention and treatment of influenza. These are effective against both influenza type A and B viruses. Development of resistance to these antiviral drugs has been identified during treatment of seasonal influenza and in sporadic oseltamivir-resistant 2009H1N1 virus, but the public health impact has been limited to date. M2 channel inhibitors, such as amantadine and rimantadine (adamantanes), are active against influenza A strains, but not influenza B strains. Adamantane resistance among circulating influenza A viruses increased rapidly worldwide beginning during 2003-2004. Therefore, amantadine and rimantadine are not recommended for antiviral treatment or chemoprophylaxis of currently circulating influenza A virus strains.

In 2009, the novel swine H1N1 strain caused an unexpected influenza pandemic as a result of reassortment of genes from human, pig, and bird's H1N1 viruses. This past pandemic, together with the ongoing circulation of highly pathogenic avian H5N1 strains and the recent emergence of the H7N9 virus, a new reassortant of avian origin isolated in China, and associated with severe respiratory disease with 40% of mortality, which could potentially adapt for human-to-human transmission, highlighted the vulnerability of the world population to novel influenza strains. Although vaccination remains the main prophylactic strategy for controlling influenza infection, to bridge the period before a new vaccine becomes available and to treat the severe influenza cases, as well as to counter the problem of viral resistance, a wider choice of anti-influenza drugs is required. Development of new influenza antivirals has therefore again become a high priority and an unmet medical need.

Prodrugs may be prepared by modifying functional groups present on the compound in such a way that the modified functional groups are cleaved, in vivo when such prodrug is administered to a subject. The modifications typically are achieved by synthesising the parent compound with a prodrug substituent. In general, prodrugs include compounds of the invention wherein a hydroxyl, amino or phosphate group is modified.

The term “polymorph” refers to the ability of the compound of the invention to exist in more than one form or crystal structure.

The term “optionally substituted” means that the atom or radical indicated in the expression using “optionally substituted” may or may not be substituted (this means substituted or unsubstituted respectively).

The term “subject” as used herein, refers to a warm-blooded animal, preferably a mammal (e.g. cat, dog, primate or human), more preferably a human, who is or has been the object of treatment, observation or experiment.

The term “pharmaceutically acceptable salt” refers to a salt of a compound that does not cause significant irritation to an organism to which it is administered and does not abrogate the biological activity and properties of the compound. In some embodiments, the salt is an acid addition salt of the compound. Pharmaceutical salts can be obtained by reacting a compound with inorganic acids such as hydrohalic acid (e.g., hydrochloric acid or hydrobromic acid), sulfuric acid, nitric acid and phosphoric acid. Pharmaceutical salts can also be obtained by reacting a compound with an organic acid such as aliphatic or aromatic carboxylic or sulfonic acids, for example formic, acetic, succinic, lactic, malic, tartaric, citric, ascorbic, nicotinic, methanesulfonic, ethanesulfonic. p-toluenesulfonic. salicylic or naphthalenesulfonic acid. Pharmaceutical salts can also be obtained by reacting a compound with a base to form a salt such as an ammonium salt, an alkali metal salt, such as a sodium or a potassium salt, an alkaline earth metal salt, such as a calcium or a magnesium salt, a salt of organic bases such as dicyclohexylamine, N-methyl-D-glucamine, tris(hydroxymethyl)methylamine, C_1-7alkylamine, Cyclohexylamine, Triethanolamine, ethylenediamine, and salts with amino acids such as arginine and lysine.

The term “solvates” covers any pharmaceutically acceptable solvates that the compounds of Formula (I), as well as the prodrugs and the salts thereof, are able to form. Such solvates are for example hydrates, alcoholates, e.g. ethanolates, propanolates, and the like.

The term “therapeutically effective amount” as used herein, means that amount of active compound or pharmaceutical agent that elicits the biological or medicinal response in a tissue system, animal or human that is being sought by a researcher, veterinarian, medicinal doctor or other clinician, which includes alleviation or reversal of the symptoms of the disease or disorder being treated.

The term “composition” is intended to encompass a product comprising the specified ingredients in the specified amounts, as well as any product which results, directly or indirectly, from combinations of the specified ingredients in the specified amounts.

The term “treatment”, as used herein, is intended to refer to all processes wherein there may be a slowing, interrupting, arresting or stopping of the progression of a disease, but does not necessarily indicate a total elimination of all symptoms.

The term “compounds of Formula (I)”, or “the present compounds” or similar terms, it is meant to include the compounds of Formula (I), including the possible stereochemically isomeric forms, and their pharmaceutically acceptable salts and solvates.

As used herein, any chemical formula with bonds shown only as solid lines and not as solid or hashed wedged bonds, or otherwise indicated as having a particular configuration (e.g. R, S) around one or more atoms, contemplates each possible stereoisomer, or mixture of two or more stereoisomers.

When a stereocenter is indicated with ‘RS’ this means that a racemic mixture was obtained at the indicated centre, unless otherwise indicated. The stereochemical configuration for centres in some compounds may be designated “R” or “S” when the mixture(s) was separated; for some compounds, the stereochemical configuration at indicated centres has been designated as “R*”, “S*”, “*R” or “*S” when the absolute stereochemistry is undetermined although the compound itself has been isolated as a single stereoisomer and is enantiomerically/diastereomerically pure.

“E*”, “Z*”, “*E” or “*E” when shown in a compound containing a double bond refer to a double bond for which the configuration is undetermined although the compound itself has been isolated as a single stereoisomer.

Pure stereoisomeric forms of the compounds and intermediates as mentioned herein are defined as isomers substantially free of other enantiomeric or diastereomeric forms of the same basic molecular structure of said compounds or intermediates. In particular, the term “stereoisomerically pure” concerns compounds or intermediates having a stereoisomeric excess of at least 80% (i.e. minimum 90% of one isomer and maximum 10% of the other possible isomers) up to a stereoisomeric excess of 100% (i.e. 100% of one isomer and none of the other), more in particular, compounds or intermediates having a stereoisomeric excess of 90% up to 100%, even more in particular having a stereoisomeric excess of 94% up to 100% and most in particular having a stereoisomeric excess of 97% up to 100%, or of 98% up to 100%. The terms “enantiomerically pure” and “diastereomerically pure” should be understood in a similar way, but then having regard to the enantiomeric excess, and the diastereomeric excess, respectively, of the mixture in question.

Pure stereoisomeric forms of the compounds and intermediates of this invention may be obtained by the application of art-known procedures. For instance, enantiomers may be separated from each other by the selective crystallization of their diastereomeric salts with optically active acids or bases. Examples thereof are tartaric acid, dibenzoyltartaric acid, ditoluoyltartaric acid and camphorsulfonic acid. Alternatively, enantiomers may be separated by chromatographic techniques using chiral stationary layers. Said pure stereochemically isomeric forms may also be derived from the corresponding pure stereochemically isomeric forms of the appropriate starting materials, provided that the reaction occurs stereospecifically. Preferably, if a specific stereoisomer is desired, said compound is synthesized by stereospecific methods of preparation. These methods will advantageously employ enantiomerically pure starting materials.

The diastereomeric racemates of the compounds of Formula (I) can be obtained separately by conventional methods. Appropriate physical separation methods that may advantageously be employed are, for example, selective crystallization and chromatography, e.g. column chromatography.

Melting Points

Values are either peak values or melt ranges, and are obtained with experimental uncertainties that are commonly associated with this analytical method.

DSC823e (Indicated as DSC)

For a number of compounds, melting points were determined with a DSC823e (Mettler-Toledo). Melting points were measured with a temperature gradient of 10° C./minute. Maximum temperature was 300° C.

Optical Rotations:

Optical rotations were measured on a Perkin-Elmer 341 polarimeter with a sodium lamp and reported as follows: [α]° (λ, c g/100 mL, solvent, PC).

[α]_λ^T=(100α)/(l×c): where l is the path length in dm and c is the concentration in g/100 ml for a sample at a temperature T (° C.) and a wavelength λ (in nm). If the wavelength of light used is 589 nm (the sodium D line), then the symbol D might be used instead. The sign of the rotation (+ or −) should always be given. When using this equation, the concentration and solvent are always provided in parentheses after the rotation. The rotation is reported using degrees and no units of concentration are given (it is assumed to be g/100 ml).

Example 28: Synthesis of (Compound 28A) and (Compound 28B)

Synthesis of Intermediate 28a

The reaction was performed in a sealed tube.

A mixture of 4-iodo-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one [CAS 70911-04-5] (7.8 g, 23.34 mmol), 2-propen-1-ol [CAS 107-18-6] (3.19 mL, 46.68 mmol), CuI (444 mg, 2.33 mmol), 1,10-phenanthroline [CAS 5144-89-8] (841 mg, 4.66 mmol) and Cs₂CO₃ (15.2 g, 46.68 mmol) in toluene (20 mL) was stirred vigorously at 120° C. for 18 h. The mixture was cooled down to rt and poured into water. The mixture was diluted with EtOAc and then filtered through a pad of Celite®. The Celite® was washed with EtOAc. The two layers were separated and the organic phase was dried over MgSO₄, filtered and concentrated under reduced pressure. Purification was carried out by flash chromatography over silica gel (15-40 μm, 80 g, Heptane/EtOAc from 90/10 to 80/20). The pure fractions were collected and evaporated to dryness (batch 1, m=3.4 g). The fractions containing impurities were combined and purified again by flash chromatography over silica gel (15-40 μm, 40 g, Heptane/EtOAc 95/5). The pure fractions were collected and evaporated to dryness (batch 2, m=0.6 g). The two batches were combined to give 4-(allyloxy)-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one (intermediate 28a, 4 g).

Synthesis of Intermediate 28b

At 0° C. under N₂ flow, LiAlH₄ (1M in THF) (17.7 mL, 17.7 mmol) was added dropwise to a solution of 4-(allyloxy)-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-one (intermediate 28a, 3.9 g, 14.76 mmol) in THF (80 mL). The mixture was stirred at 0° C. for 1 h and quenched with EtOAc and diluted with water. The mixture was filtered through Celite®. The organic phase was separated, dried over MgSO₄, filtered and concentrated under reduced pressure to give 4-(allyloxy)-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-ol (intermediate 28b, 3.8 g).

Synthesis of Intermediate 28c

At 0° C., SOCl₂ (1.22 mL, 16.89 mmol) was added dropwise to a solution of 4-(allyloxy)-10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-ol (intermediate 28b, 3.75 g, 14.08 mmol) in CH₂Cl₂ (70 mL). The reaction was stirred at 0° C. for 30 min and then at rt for 4 h. The mixture was concentrated to dryness, taken up with toluene and concentrated again to give 4-(allyloxy)-5-chloro-10,11-dihydro-5H-dibenzo[a,d][7]annulene (intermediate 28c, 4.2 g), which was used as such in the next step.

Synthesis of Intermediate 28d

Synthesis of Intermediate 28e

Intermediate 28e (undefined E/Z mixture, 620 mg) was obtained using the procedure described for intermediate 5f. The two enantiomers were separated via chiral SFC (Stationary phase: Whelk-O1 (S,S) 5 μm 250×21.2 mm, Mobile phase: 45% CO₂, 55% MeOH) to give the first eluted enantiomer (215 mg, undefined E/Z mixture) and the second eluted enantiomer (230 mg, undefined E/Z mixture). The first eluted enantiomer was further purified via chiral SFC (Stationary phase: Chiralcel® OD-H 5 μm 250×30 mm, Mobile phase: 60% CO₂, 40% MeOH) to give enantiomer 28eA (139 mg, pure *Z isomer). The second eluted enantiomer was further purified via chiral SFC (Stationary phase: Chiralpak® AD-H 5 μm 250×30 mm, Mobile phase: 60% CO₂, 40% MeOH) to give enantiomer 28eB (129 mg, pure *Z isomer).

Synthesis of Compound 28A

LiCl (54 mg, 1.27 mmol) was added to a solution of 28eA (139 mg, 0.26 mmol) in DMA (1.44 mL) and the reaction was stirred at 80° C. for 4 h. The mixture was cooled to rt and HCl 0.5N in ice was added. The aqueous layer was extracted with CH₂Cl₂. The combined organic layers were washed 3 times with HCl 0.5N, dried over MgSO₄, filtered and concentrated under reduced pressure. Purification was carried out by flash chromatography over silica gel (15-40 μm, 4 g, CH₂Cl₂/CH₃OH from 99/1 to 97/3). The pure fractions were collected and evaporated to dryness to give, after freeze-drying in 10 mL of CH₃CN/water (2/8), Compound 28A (65 mg).

The reaction was quenched by the addition of ice and water. The mixture was extracted with EtOAc and the combined organic layers were washed with water, dried over MgSO₄, filtered and concentrated to dryness. The residue was taken up with a minimum amount of EtOAc. The precipitate was filtered off and dried to give a first batch of 3-allyl-1-(10-(allyloxy)-6,11-dihydrodibenzo[b,e]thiepin-11-yl)-5-(benzyloxy)-2,3-dihydro-1H-pyrido[2,1-f][1,2,4]triazine-4,6-dione (intermediate 46a, 12.5 g). The filtrate was concentrated under reduced pressure. Purification of the residue was carried out by flash chromatography over silica gel (30 μm, 220 g, CH₂Cl₂/CH₃OH from 99/1 to 96/4). The fractions containing the expected compound were collected and concentrated to dryness. This fraction was taken up with EtOAc and the precipitate was filtered off to give a second batch of intermediate 46a (2.65 g).

Synthesis of Intermediate 46b

The reaction was performed in an Anton-Paar microwave oven in 4 batches of 3.47 g of intermediate 46a.

A degassed solution of 3-allyl-1-(10-(allyloxy)-6,11-dihydrodibenzo[b,e]thiepin-11-yl)-5-(benzyloxy)-2,3-dihydro-1H-pyrido[2,1-f][1,2,4]triazine-4,6-dione (intermediate 46a, 13.9 g, 24.06 mmol) and Hoveyda-Grubbs catalyst 2nd generation [CAS 301224-40-8) (3.0 g, 4.81 mmol) in dry DCE (1.5 L) was stirred at 80° C. for 35 min. SiliaMetS® DMT (31.5 g, 19.25 mmol) was added and the mixture was stirred at rt for 18 h. The reaction mixture was filtered through Celite®. The Celite® was washed with CH₂Cl₂ and the filtrate was concentrated under reduced pressure. Purification was carried out by flash chromatography over silica gel (30 μm, 330 g, CH₂Cl₂/CH₃OH from 99.5/0.5 to 97/3). A second purification was carried out by flash chromatography over silica gel (15 μm, 120 g, Toluene/iPrOH 93/7). The pure fractions were collected and concentrated under reduced pressure to afford 16-(benzyloxy)-6,10,13,21a-tetrahydro-7,8-(epiprop[1]en[1]yl[3]ylidene)-14,21-methanobenzo[6,7]thiepino[4,5-c]pyrido[1,2-f][1]oxa[5,6,9]triazacyclotridecane-15,17-dione (mixture of Z and E isomers, intermediate 46b, 1.98 g).

Antiviral Activity

Example A

Influenza Antiviral Assay

Human lung carcinoma A549 cells (ATCC, Manassas, Va.) were plated at a density of 5×10⁴ cells/mL (10×10³ cells/well) in assay media (Ham's F12 media supplemented with 0.3% FBS, 1% penicillin/streptomycin, 1% L-Glutamine, and 1% non-essential amino acids (all Mediatech, Manassas, Va.) and 1% DMSO (Sigma-Aldrich, St Louis, Mo.)) in white 96-well plates. Cells were infected with 250 IU/well of Influenza strain A549 A/WSN/33 (H1N1) (Virapur, San Diego Calif.) and incubated for 20 hours at 37° C., 5% CO2. The cell culture supernatant was aspirated off and 50 μL of 25 μM 2′-(4-Methylumbelliferyl)-a-D-N-acetylneuraminic acid (Sigma-Aldrich) dissolved in 33 mM MES, pH 6.5 (Emerald Biosystems, Bainbridge Island, Wash.) was added to the cells. After incubation for 45 min at 37° C., reactions were stopped by addition of 150 μL stop solution (100 mM glycine, pH 10.5, 25% ethanol, all Sigma-Aldrich). Fluorescence was measured with excitation and emission filters of 355 and 460 nm, respectively, on a Victor X3 multi-label plate reader (Perkin Elmer, Waltham, Mass.). Cytotoxicity of uninfected parallel cultures was determined by addition of 100 μL of CellTiter-Glo® reagent (Promega, Madison, Wis.), and incubation for 10 min at RT. Luminescence was measured on a Victor X3 multi-label plate reader.

Example B

EN PA FRET Inhibition Assay

EN PA FRET inhibition assay was performed using a 19 nucleotide synthetic oligoribonucleotide substrate: 5 ‘-FAM-AUUUUGUUUUUAAUAUUUC-BHQ-3’ (Integrated DNA Technologies, Inc., Coralville, Iowa) (SEQ. ID. NO. 1). Upon RNA cleavage, the fluorescent FAM group is released from the BHQ quencher. The PA sequence used to produce active enzyme is derived from any one of multiple influenza A virus strains (e.g., A/goose/Nanchang/3-120/01 (H3N2), A/Victoria/3/1975 (H3N2), A/Brisbane/10/2007 (H3N2), A/WSN/33 (H1N1), A/CA/4/2009 (H1N1), A/CA/5/2009 (H1N1), A/Shanghai/1/2013 (H7N9), A/Guizhou/1/2009 (H5N1)). The full length recombinant protein was expressed from a baculovirus vector in insect cells. Full length EN PA was used in this assay at an effective concentration of 1 to 10 nM, together with 50 nM FRET probe with a final volume of 20 ml cleavage buffer (20 mM Tris Ph8, 100 mM NaCl, 5% Glycerol, 10 mM β-ME, 0.0003% Tween-20, 5 mM MgCl₂).

Compounds described herein were added to a 384-well black polypropylene plate. Fluorescence was measured in a continuous mode up to 120 minutes with a Wallac 1420 Victor³V multilabel counter (PerkinElmer Life Sciences, Shelton, Conn.) (excitation 485 nm; emission 535 nm). Measured IC₅₀ is defined as the concentration at which fluorescence is 50% that of the uninhibited control (DMSO). IC₅₀ was calculated by fitting the data to the sigmoidal equation Y=% Min+(% Max−% Min)/(1+X/IC₅₀), where Y corresponds to the percent relative enzyme activity, Max is the maximum enzyme activity in the presence of DMSO, Min is the inhibited activity at saturating concentration of compound, and X corresponds to the compound concentration. The IC₅₀ values were derived from the mean of a minimum of two independent experiments.

Table 1A shows the antiviral data obtained against influenza A H1N1 strain and cellular toxicity.
