FIELD

The present invention concerns a selected range of compounds comprising 2-pyridone or 5-pyridone, and pharmaceutically-acceptable salts and compositions of such compounds. The compounds can be used as anti-inflammatory and anticancer therapies. Therefore, the present invention also concerns compounds comprising 2-pyridone or 5-pyridone for use as medicaments, particularly for the treatment of inflammatory diseases and oncology.

BACKGROUND

Bromodomain and Extra-Terminal (BET) proteins are a family of four bromodomain-containing (BRD) proteins (BRD2, BRD3, BRD4 and BRDT). All four members contain two BRDs (located next to each other toward the N-terminal of the proteins) and an extra-terminal domain (Shi, J. et al. Cancer Cell 25(2):210-225 (2014)). The two BRDs in each BET protein are designated binding domain I (BDI) and binding domain II (BDII). The BRD is a functional protein domain that contains a defined and predominantly hydrophobic pocket that binds to acetylated lysine residues, typically those found on transcription factors (Shi, J. et al. Cancer Cell 25(2):210-225 (2014)) or on the N-terminal tails of histone proteins. BRDs function as epigenetic regulators, i.e. they functionally alter gene activity and expression without altering the DNA sequence. For example, BRD4 recruits the transcription factor P-TEFb to promoters leading to altered expression of genes involved in the cell cycle (Yang et al., Mol. Cell Biol. 28: 967-976 (2008)). BRD2 and BRD3 also regulate growth promoting genes (LeRoy et al., Mol Cell 30:51-60 (2008)). Therefore, BRDs are responsible for transducing the signals carried by acetylated lysine residues into various phenotypes. BETs are considered in the art to be ubiquitously expressed in humans except for BRDT, which is normally expressed in the testes but is also expressed by some cancers (Ekaterina B. F. et al. Cell J. 19(Suppl 1): 1-8 (2017)).

BET proteins have roles in the regulation of biochemical pathways such as MYC, BCL2, F0SL1, P-TEFb, NFkB, Glucocorticoid signalling and others (Shi J. et al. Mol Cell. Jun 5;54(5):728-36 (2014)), (Hajmirza A. Biomedicines. Feb 6;6(1). pii: E16 (2018)), (Shan N. Elife. Sep 11;6. pii: e27861. (2017)), (Huang B. Mol Cell Biol. Mar;29(5):1375-87 (2009)). As such, BET inhibitors are considered to have potential uses in a range of inflammatory diseases, cancers, infections, metabolic diseases, CNS disorders, fibrotic diseases and cardiac diseases (Deanna A. M. et al. J Exp Med. Oct 21; 210(11): 2181-2190 (2013)), (Rab K. P. et al. Trends Pharmacol. Sci. Mar;33(3):146-53 (2012)), (Anna C. B. et al. J Immunol. Apr 1; 190(7): 3670- 3678 (2013)), (Zuber J. et al. Nature. Aug 3;478(7370):524-8. (2011)), (Montserrat P. S. et al. Epigenetics.; 12(5): 323-339 (2017)), (Qiming D. et al. Sci Transl Med. May 17; 9(390): eaah5084. (2017)), (Kristin M. K et al. J Biol Chem. Aug 11; 292(32): 13284-13295 (2017)), (Ning D. et al. PNAS December 22, 112 (51) 15713-15718 (2015)).

Compounds that can inhibit or affect the function of BET proteins have the potential to modulate gene expression and treat diseases that are at least in part caused by abnormal regulation of BET protein activity. Several small molecules have been reported to be effective in BET inhibition, including diazepine-, 3,5- dimethylisoxazole-, thiazol-2-one-, diazobenzene-, and 4-acylpyrrole-based compounds (see M. Brand et al, ACS Chem. Biol. 2015, 10, 22-39, W02011054553, W02011054845). Compounds that can selectively inhibit the function of BDII over BDI have the potential to modulate gene expression and treat diseases that are at least in part caused by abnormal regulation of BET protein activity while offering the potential of an improved therapeutic index. Several small molecules have been reported to be effective in selectively inhibiting the function of BET BDII over BDI, including (BY27, RVX-297, ABBV744, GSK046, GSK620, GSK549 (Chen D. et. al. Eur J Med Chem 182, 2019, 111633), (Wells P. S. et. al. Proc. Natl. Acad. Sci. U. S. A. 2013, 110, 19754-19759) (Sheppard G. S. et. al. J. Med. Chem. 2020, 63, 10, 5585-5623), (Preston A. et. al. J. Med. Chem. 2020, 63, 17, 9070-9092), (Seal J. T. et. al. J. Med. Chem. 2020, 63, 17, 9093-9126). Improved therapeutic index and pre-clinical safety of BDII selective BET inhibitors verses pan-BET inhibitors have been demonstrated (E. Faivre et al. Nature 578, 306-310 (2020)).

Compounds comprising 6-methyl-l,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7- one moieties, substituted at the 4- and/or 2 -positions are described in patent applications WO 2017177955, WO 2015081280, WO 2014206150, WO 2014206345, WO 2013097601, WO 2013097052 and WO 2018130174 as useful for the inhibition of BET proteins.

The present invention provides alternative BET protein inhibitors that can be used in the treatment or prophylaxis of the conditions described herein.

SUMMARY

It has been found that the selected compounds and compositions of this teaching are surprisingly active and selective in inhibiting all four BET BRDs at binding domain II (BDII) and are less active in inhibiting all four BET BRDs at binding domain I (BDI). The compounds and compositions are surprisingly selective for BDII over BDI offering the potential of an improved therapeutic index and a lower risk of side-effects. The compounds and compositions have surprisingly long half-lives when dosed to rodents, offering potential use as medicaments for oral and/or topical administration.

Improving IV half life

The efficacy of drugs is often driven by a continuous coverage of the minimum efficacious plasma concentration. Half-life must therefore be adapted to achieve a desired pharmacokinetic profile. Often a drugs half-life in mice is often greater than 1 hour. For systemic delivery, in some embodiments the half-life is longer e.g., >1 hour. For topical delivery, in some embodiments the half-life is shorter e.g., <1 hour.

DETAILED DESCRIPTION

In one or more embodiments, the selective derivatives of 2-pyridone or 5- pyridone disclosed herein have been found to be surprisingly effective in inhibiting all four BET BRDs at binding domain II (BDII). In one or more embodiments, the compounds herein may also have an effect in inhibiting BET BRDs at binding domain I (BDI). In one or more embodiments, the compounds show a greater selectivity for BDII over BDI. In some embodiments the compounds bind effectively to both BDII and BDI. Such compounds may be effective as PAN BET inhibitors.

In one or more embodiments the compounds can have a therapeutic effect systemically. In some embodiments the compounds may be effective therapeutically by administration topically. In some embodiments, e.g., when applied topically systemic penetration is low and below a therapeutic window. In other embodiments, e.g., when applied topically systemic penetration may be sufficient for the compounds to have a systemic therapeutic effect in addition to any topical effect. In some embodiments the administration is designed to be intradermal. In some embodiments the administration is designed to be transdermal. In one or more embodiments systemic delivery may be by any of the known acceptable forms of systemic delivery of the compound or a pharmaceutical composition comprising the compound, including oral, and injection. Topical delivery can be by application of the compound or a pharmaceutical composition comprising the compound to the skin or mucosal surface of a subject, including internal surfaces of body cavities, such as the gastrointestinal tract, vagina, air passageways and lungs. Where compounds have higher selectivity for BDII they may in one or more embodiments be more suited for systemic delivery. Such compounds which also have the property of a longer half-life may in one or more embodiments be more effective systemically. Potential half-life may be indicated by factors like the liver clearance rate and plasma stability. Such compounds which have both the properties of a lower liver clearance rate and a higher plasma stability may in one or more embodiments be more effective systemically. Compounds which have both the reverse properties of a higher liver clearance rate and a lower plasma stability may in one or more embodiments be more effective topically. The potential to be effective against one or more disorders or diseases described herein may in one or more embodiments be illustrated by the ability of the compounds to modulate or reduce biomarkers known or implicated for example in an inflammatory or immune response. A non limiting example would be the reduction in the levels of IL-17 or IL-22.

A non-exhaustive list of methods of administration of the compounds includes, buccally, by inhalation spray, intraperitoneal, intrapulmonary, intradermal, epidural or via an implanted reservoir, nasally, orally, parenterally, rectally, topically, transdermally, sublingually, and vaginally.

The compounds are now described in detail.

In the discussion that follows, reference is made to a number of terms, which have the meanings provided below, unless a context indicates to the contrary. The nomenclature used herein for defining compounds, in particular the compounds according to the invention, is in general based on the rules of the IUPAC organisation for chemical compounds, specifically the "IUPAC Compendium of Chemical Terminology (Gold Book)”. For the avoidance of doubt, if a rule of the IUPAC organisation is contrary to a definition provided herein, the definition herein is to prevail. Furthermore, if a compound structure is contrary to the name provided for the structure, the structure is to prevail.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art to which this disclosure belongs. All ranges disclosed herein include the endpoints. The use of the term "or” shall be construed to mean "and/or” unless the specific context indicates otherwise. All patents, applications, published applications, and other publications are incorporated by reference in their entirety. In the event that there is a plurality of definitions for a term herein, those in this section prevail unless stated otherwise. The term "therapeutic index”, also known as the "therapeutic window” or "safety window” defines the relative safety of a drug. The therapeutic index may be calculated as the ratio of the area under the curve (AUG) in blood, at a concentration of drug that results in no toxicity (No Observed Adverse Effect Level - NOAEL), to the concentration of drug that produces the desired efficacy, typically the dose that has a 50% effect - the Effective dose 50 or ED50. TI = AUC(NOAEL)/AUC(ED50). A drug with a higher therapeutic index is preferable, since administration of the drug is less likely to lead to unwanted side effects, and more drug may be administered to treat a subject more effectively. The desired efficacy of BET inhibitors is driven by their inhibition of the function of BDII, whereas inhibition of the function of BDI leads to unwanted side effects. Thus, drugs that selectively inhibit the function of BDII over BDI have the potential to modulate gene expression and treat diseases that are at least in part caused by abnormal regulation of BET and are less likely to give rise to unwanted side effects with respect to pan inhibitors administered at the same dose. A higher dose of drugs that selectively inhibit BDII over BDI may be safely administered with respect to pan inhibitors, thus such selective drugs may be more efficacious.

The term "cyclic” or variants thereof defines a compound, or a substituent group on the compound, in which one or more series of atoms in the compound or substituent is connected to form a ring. Whereas, the term "acyclic” defines a compound or substituent containing no rings of atoms.

The term "treatment" defines the therapeutic treatment of a human or nonhuman animal, in order to impede or reduce or halt the rate of the progress of the condition, or to ameliorate or cure the condition. Prophylaxis of the condition as a result of treatment is also included. References to prophylaxis are intended herein not to require complete prevention of a condition: its development may instead be hindered through treatment in accordance with the invention. Typically, treatment is not prophylactic, and the compound or composition is administered to a patient having a diagnosed or suspected condition. By an "effective amount" herein defines an amount of the compound or composition that is sufficient to impede the noted diseases and thus produces the desired therapeutic or inhibitory effect.

Without wishing to be bound by theory, it is considered that selected R ₃ and R ₄ substituents provide selectivity for BET BDII over BET BDI. BET BDI has an isoleucine 161 (BRD4 numbering) residue which has increased steric bulk compared to the analogous valine 439 (BRD4 BDII numbering) residue in BET BDII (See Uniprot code 060885-1 for BRD4 protein sequence). As such, the selected R ₃ and R ₄ substituents of the present invention may cause ligands to be displaced from optimum binding with BET BDI proteins by steric clashes with the isoleucine 161 (BRD4 numbering) residue. In addition, the selected R ₃ and R ₄ substituents of the present invention may give good binding with BET BDII proteins due to the space a valine 439 (BRD4 numbering) reside affords compared to the analogous isoleucine BET BDI residue. These residue combination changes are conserved in all BET BDI and BD2 domains. Symmetrical 2,6-disubstituted phenoxy may be better able to exploit the potential selectivity gains between BET BDI and BDII. A number of the selected compounds defined in the present invention, exemplified by the compounds labeled "NA’17-22” and "NA’44”, and defined herein (but not limited thereto) particularly seek to exploit the benefits of this symmetry to optimize selectivity between BET BDI and BD II.

In some embodiments of the first aspect, the pyridone is a 5-pyridone. Advantageously, it is considered that compounds of the present invention comprising 5-pyridone provide improved binding affinity for BET proteins as well as longer half-life in pharmacokinetic studies.

In some embodiments of the first aspect involving sections (a) or (c) R ² is methyl. It is considered that compounds where R ² is methyl provide a lower lipophilicity (logD) and molecular weight (MW), which can lead to an improved pharmacokinetic profile, such as a longer drug half-life in animals and humans.

In the selected compounds of the first aspect based on section (a), R1 is a CONH- group. The amine may form hydrogen bond interaction with Asparagine 429 (BRD2 BDII numbering) residue to improve activity which may lead to more efficacious drugs.

It is considered that compounds of the present invention with these selected substituents provide further selected bioavailability, particularly during systemic administration. This may provide a lower required dose or dosage regime, due to increased in vivo stability, including plasma stability, and lower liver metabolism. In particular the Ri groups claimed may reduce (plasma) instability from amide hydrolysis while also lowering liver metabolism rates resulting in longer drug halflife when dosed to animals or humans.

It is further considered that the selection of small alkyl, cycloalkyl and cyclic ether groups in the Ri substituent of the compounds of the present invention, exemplified but not limited to the compounds labelled "AA’1-3,5,6” as described herein may further improve selectivity for BET BDII over BET BDI, by better fitting into the groove made by Histidine 437 and Proline 434 residues in BDII (BRD4 numbering) amino acid residues in this part of all BET BDII protein structures. Histidine 437 and Proline 434 residues in BDII (BRD4 numbering) are changed with Aspartic acid 144 and Lysine 141 residues in BDI (BRD4 numbering). These Aspartic acid 144/Lysine 141 and Histidine 433/Proline 430 residue combination changes are conserved in all BET BDI and BD2 domains.

It is also further considered that the selection of a 'basic’ substituent in the Ri substituent of the compounds of the present invention, exemplified but not limited to the compounds labelled "AA’7-11” as described herein, may increase the ratio of drug levels in body tissues, relative to drug levels in blood (also referred to as the "volume of distribution”), which in turn may increase or improve half-life which may improve duration of action leading to more efficacious compositions.

It is also further considered that the selection of C ₃ -C ₆ cyclofluoroalkyl or C ₁ - C ₆ fluoroalkyl groups in the Ri substituent of the compounds of the present invention, exemplified but not limited to the compounds labelled "AA’ 4, 12-15” as described herein may increase or improve half-life which may improve duration of action leading to more efficacious compositions.

In one or more embodiments there is provided a compound, wherein the compound is selected from the compounds labelled AA’l to AA’15 as illustrated herein. In one or more embodiments there is provided a compound, wherein the compound is selected from labelled AA’l, AA’5, AA’6 AA’12 to AA’15. In one or more embodiments there is provided a compound, wherein the compound is selected from labelled AA’l, AA’6 and AA’13. In one or more embodiments the aforesaid selections are for systemic uses, e.g. by oral delivery. It is considered that compounds of the present invention with these selected substituents provide greater bioavailability, particularly during systemic administration and improved BDII/BDI selectivity. This therefore equates to a lower required dose or dosage regime due to reduced drug metabolism in the liver and/or increased drug binding to blood proteins and/or tissues. Together these improvements lead to a longer half-life of drug when dosed to animals or humans. R ₂ groups may also lead to increased selectivity for BDII over BDI activity due to more favorable interactions with the BDII protein.

It is further considered that the selection of 'basic’ substituent in the R ₂ substituent of the compounds of the present invention, exemplified but not limited to the compounds labelled "NA’ 3, 5, 10 and 15” (as illustrated herein) as described may increase volume of distribution which in turn may increase half-life which may improve duration of action leading to more efficacious or safer drugs.

Inflammatory diseases rely on T helper cells Thi, Th2 and Thi? for innate and adaptive immunity responses which affect either or both of the acute or chronic stages of the disease. Many cytokine and chemokines are upregulated in an inflammatory disease and the ability to reduce the levels of these inflammatory markers is evidence of the ability of a drug to ameliorate a disease. Such cytokine and chemokines include but are not limited to granulocyte-macrophage colonystimulating factor (GM-CSF); interleukins IL-1, IL-2, IL-4, IL-6, IL-8, IL-13, IL-17, IL- 22; chemokine (c-c motif) ligands CCL2, CCL27 and CCL20; tumour necrosis factor alpha (TNF-a); thymic stromal lymphopoietin (TSLP); and chemokine (c-x-c motif) ligand 9 (CXCL9). Unselective BET inhibitors inhibit most markers of inflammation listed above. The selective BET BDII inhibitors described herein affect fewer markers of inflammation including, but are not limited to, interleukins (IL-4, IL-17, IL-33, IL-36); chemokine (c-c motif) ligand 2 (CCL2); and chemokine (c-x-c motif) ligand 10 (CXCL10). These important markers of disease predict efficacy for many inflammatory diseases, while selective BET BDII inhibitors focused profile suggests such compounds have an improved therapeutic index.

Process for Preparation

The following schemes illustrate methods of synthesising analogues of the compounds of the invention which allow the skilled reader to prepare the analogous compounds of the invention. Scheme 1 illustrates a general route for the preparation of compounds herein via Suzuki coupling of intermediates (III) and (IX) followed by deprotection. The 6-methyl-l,6-dihydro-7H-pyrrolo[2,3-c]pyridin-7- one boronic ester intermediate (III) is prepared as follows: 5 -Bromo-2-methoxy-4-methyl-3 -nitropyridine is reacted with DMF-DMA to give intermediate (VIII). An iron catalysed reduction of the 3-nitro group to the corresponding amine initiates ring closure to give intermediate (VII). Tosyl protection followed by acid hydrolysis with HBr gives intermediate (V). The pyridone group is then N-methylated with methyl iodide and sodium hydride to give intermediate (IV). Intermediate (III) is then formed from the 4-bromoaryl compound (IV) via treatment with 4,4,4',4',5,5,5',5'-Octamethyl-2,2'-bi-l,3,2- dioxaborolane in a palladium-catalysed coupling reaction. Suzuki coupling of (III) and (IX), followed by deprotection, produces compound (II). Deprotection involves removal of the tosyl group of intermediate (III) using, for example, sodium hydroxide.

Alternatively, the compound may be functionalised at position 2 of the pyrrole with a third substituent, typically CONHethyl. This may be carried out by using an alternative synthetic pathway, shown in Scheme 2, in which intermediate (IV) is reacted with ethylchloroformate and a strong base, such as lithium diisopropylamide (LDA) to form intermediate (IV’). Intermediate (III') is then formed from compound (IV’) via treatment with 4,4,4',4',5,5,5',5'-Octamethyl-2,2'- bi-l,3,2-dioxaborolane in a palladium-catalysed coupling reaction. Suzuki coupling of (III') and (IX), followed by deprotection, produces compound (II’). Deprotection involves removal of the tosyl group using, for example, sodium hydroxide. This also converts the ethoxy substituent of the ethyl formyl to a hydroxy group. Finally, the carboxylic acid at position 2 of the pyrrole of intermediate (IF) is reacted with a suitable amine to produce the desired third substituent. Oxalyl chloride is typically used to catalyse this reaction step by first converting the carboxylic acid to an acyl chloride, which is more susceptible to nucleophilic substitution with an amine. The skilled person is able to assess which amines and reaction conditions are suitable to functionalise the carboxylic acid of intermediate (IF) to produce compound (II”).

Scheme 1: general synthetic pathway for the synthesis of compounds herein. The definitions of R2, R3, R4 and R5 of compounds (IX) and (II) are as defined above for compounds of formula (I).

Suitable pathways to synthesise intermediates of formula (IX) are shown in Scheme

4, in which (IX) can be a substituted R2 substituted 2-pyridone or substituted R2 substituted 5-pyridone.

Substituted N-methyl-2-pyridone-intermediates (XI) and substituted N- methyl-5-pyridone-intermediates (XI') are prepared via methylation of the corresponding 2-pyridone (XII) or 5-pyridone (XIT) and hydrolysis of the corresponding pyridines (XIII) or (XIII’) using potassium hydroxide. Pyridine intermediates (XIII) or (XIII') are in turn formed via reduction of the corresponding pyridine oxides (XIV) or (XIV’) using phosphorus tribromide. Bromo-intermediates (XIV) or (XIV) are prepared via reaction of the corresponding nitro intermediates (XV) or (XV) with acetyl bromide, and compounds (XV) or (XV) are in turn produced via S _N Ar reaction of the corresponding ortho-fluoro nitro pyridine oxide compounds (XVI) or (XVI’). The definitions of Ri, R ₂ , R ₃ , R ₄ and R ₅ for compounds (XI), (XI’), (XII), (XII’), (XIII), (XIII’), (XIV), (XIV), (XV), (XV), (XVI) and (XVI’) are as defined above for formula (I).

Bromodomain assay procedure

T7 phage strains displaying bromodomains were grown in parallel in 24- well blocks in an E. coli host derived from the BL21 strain. E. coli were grown to logphase and infected with T7 phage from a frozen stock (multiplicity of infection = 0.4) and incubated with shaking at 32°C until lysis (90-150 min). The lysates were centrifuged (5,000 x g) and filtered (0.2 pm) to remove cell debris. Streptavidin- coated magnetic beads were treated with biotinylated small molecule or acetylated peptide ligands for 30 min at RT to generate affinity resins for bromodomain assays. The ligated beads were blocked with excess biotin and washed with blocking buffer (SeaBlock (Pierce), 1 % BSA, 0.05 % Tween 20, 1 mM DTT) to remove unbound ligand and to reduce non-specific phage binding. Binding reactions were assembled by combining bromodomains, ligated affinity beads, and test compounds in lx binding buffer (16 % SeaBlock, 0.32x PBS, 0.02%BSA, 0.04 % Tween 20, 0.004% Sodium azide, 7.9 mM DTT). Test compounds were prepared as 1000X stocks in 100% DMSO and subsequently diluted 1:25 in MEG. The compounds were then diluted directly into the assays such that the final concentrations of DMSO and MEG are 0.1% and 2.4%, respectively. All reactions were performed in polypropylene 384-well plates in a final volume of 0.02 ml. The assay plates were incubated at RT with shaking for 1 hr and the affinity beads were washed with wash buffer (lx PBS, 0.05% Tween 20). The beads were then re-suspended in elution buffer (lx PBS, 0.05% Tween 20, 2 μM non-biotinylated affinity ligand) and incubated at RT with shaking for 30 min. The bromodomain concentration in the eluates was measured by quantitative polymerase chain reaction (qPCR).

An 11 -point 3 -fold serial dilution of each test compound was prepared in 100% DMSO at lOOOx final test concentration. All compounds were distributed by acoustic transfer (non-contact dispensing) in 100% DMSO. The compounds were then diluted directly into the assays such that the final concentration of DMSO is 0.09%. Most dissociation constants were determined using a compound top concentration = 10,000 nM. If the initial dissociation constant determined is < 0.169 nM (the lowest concentration tested), the measurement was repeated with a serial dilution starting at a lower top concentration.
