Description

FIELD OF THE INVENTION

The present invention provides pharmaceutically active pyrazolo[1,5-a]pyrazin-4-yl and related TYK2 ligands and analogues. Such compounds are useful for inhibiting Janus Kinases (JAKs). This invention also is directed to compositions comprising methods for making such compounds, and methods for treating and preventing conditions mediated by JAK.

BACKGROUND OF THE INVENTION

Protein kinases are families of enzymes that catalyze the phosphorylation of specific residues in proteins, broadly classified into tyrosine and serine/threonine kinases. Inappropriate kinase activity, arising from mutation, over-expression, or inappropriate regulation, dys-regulation or de-regulation, as well as over- or under-production of growth factors or cytokines has been implicated in many diseases, including but not limited to cancer, cardiovascular diseases, allergies, asthma and other respiratory diseases, autoimmune diseases, inflammatory diseases, bone diseases, metabolic disorders, and neurological and neurodegenerative disorders such as Alzheimer's disease. Inappropriate kinase activity triggers a variety of biological cellular responses relating to cell growth, cell differentiation, cell function, survival, apoptosis, and cell mobility implicated in the aforementioned and related diseases.

Thus, protein kinases have emerged as an important class of enzymes as targets for therapeutic intervention. In particular, the JAK family of cellular protein tyrosine kinases (JAK1, JAK2, JAK3, and Tyk2) play a central role in cytokine signaling (Kisseleva et al., Gene, 2002, 285, 1; Yamaoka et al. Genome Biology 2004, 5, 253)). Upon binding to their receptors, cytokines activate JAK which then phosphorylate the cytokine receptor, thereby creating docking sites for signaling molecules, notably, members of the signal transducer and activator of transcription (STAT) family that ultimately lead to gene expression. Numerous cytokines are known to activate the JAK family. These cytokines include, the interferon (IFN) family (IFN-alpha, IFN-beta, IFN-omega, Limitin, IFN-gamma, IL-10, IL-19, IL-20, IL-22), the gp130 family (IL-6, IL-11, OSM, LIF, CNTF, NNT-1/BSF-3, G-CSF, CT-1, Leptin, IL-12, IL-23), gamma C family (IL-2, IL-7, TSLP, IL-9, IL-15, IL-21, IL-4, IL-13), IL-3 family (IL-3, IL-5, GM-CSF), single chain family (EPO, GH, PRL, TPO), receptor tyrosine kinases (EGF, PDGF, CSF-1, HGF), and G-protein coupled receptors (AT1).

There remains a need for new compounds that effectively and selectively inhibit specific JAK enzymes: TYK2 in particular. TYK2 is a JAK kinase family member, and is important in the signaling of the type I interferons (including IFNalpha, INFbeta), IL-6, IL-10, IL-12 and IL-23 (Liang, Y. et al., Expert Opinion on Therapeutic Targets, 18, 5, 571-580 (2014)). As such, TYK2 signals with other members of the JAK kinase family in the following combinations: TYK2/JAK1, TYK2/JAK2, TYK2/JAK1/JAK2. TYK2 has been shown to be important in the differentiation and function of multiple cell types important in inflammatory disease and autoimmune disease including natural killer cells, B cells, and T helper cell types. Aberrant TYK2 expression is associated with multiple autoimmune or inflammatory conditions. Modulation of immune activity through inhibition of TYK2 kinase activity can prove useful in the treatment of various immune disorders (O'Shea J J, Plenge R, Immunity, 36, 542-50 (2012); Murray, P. J., J. Immunol., 178, 2623-2629 (2007); Kisseleva, T., et al., Gene, 285, 1-24 (2002)) while avoiding JAK2 dependent erythropoietin (EPO) and thrombopoietin (TPO) signaling (Neubauer H., et al., Cell, 93(3), 397-409 (1998); Parganas E., et al., Cell, 93(3), 385-95 (1998)).

Examples of such groups include methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, sec-butyl, tert-butyl, pentyl, iso-amyl and hexyl. Unless otherwise specified, an alkyl group comprises from 1 to 6 carbon atoms. The carbon atom content of alkyl and various other hydrocarbon-containing moieties is indicated by a prefix designating a lower and upper number of carbon atoms in the moiety, that is, the prefix C_i-C_j indicates a moiety of the integer “i” to the integer “j” carbon atoms, inclusive. Thus, for example, C₁-C₆ alkyl refers to alkyl of one to six carbon atoms, inclusive.

The term “hydroxy,” as used herein, means an OH group. The term “heterocyclic” refers to a saturated or partially saturated (i.e., non aromatic) heterocycle which contains three to ten ring atoms where one or more, preferably, one, two or three ring atoms, are heteratom(s) selected from N, O and S, the remaining being carbon, and which may be attached via a ring nitrogen atom or a ring carbon atom. Equally, when substituted, the substituent may be located on a ring nitrogen atom (if the substituent is joined through a carbon atom) or a ring carbon atom (in all cases). Specific examples include oxiranyl, aziridinyl, oxetanyl, azetidinyl, tetrahydrofuranyl, pyrrolidinyl, tetrahydropyranyl, piperidinyl, 1,4-dioxanyl, morpholinyl, piperazinyl, azepanyl, oxepanyl, oxazepanyl and diazepinyl.

The term “aryl” refers to an aromatic monocyclic or bicyclic hydrocarbon containing six to ten ring carbon atoms which may be attached via one of the ring carbon atoms. Equally, when substituted, the substituent may be located on a ring carbon atom. Specific examples include, but are not limited to, phenyl, tolyl, xylyl, trimethylphenyl, and naphthyl. Examples of aryl substituents include, but are not limited to, alkyl, hydroxyl, halo, nitrile, alkoxy, trifluoromethyl, carboxamido, SO₂Me, benzyl, and substituted benzyl.

The term “heteroaryl” refers to a monovalent aromatic monocyclic or bicyclic heterocycle of five to ten ring atoms where one or more, preferably, one, two or three ring atoms, are heteratom(s) selected from N, O, and S, the remaining being carbon, and which may be attached via a ring carbon atom or a ring nitrogen atom with an appropriate valency. Equally, when substituted, the substituent may be located on a ring carbon atom or a ring nitrogen atom with an appropriate valency. Specific examples include, but are not limited to, thienyl, furanyl, pyrrolyl, pyrazolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, isothiazolyl, triazolyl, oxadiazolyl, thiadiazolyl, tetrazolyl, pyridyl, pyridazinyl, pyrimidinyl and pyrazinyl.

In some embodiments, livestock are suitable for consumption by mammals, for example humans. Examples of livestock animals include cattle, goats, horses, pigs, sheep, including lambs, and rabbits, as well as birds, such as chickens, ducks and turkeys.

The term “treating” or “treatment” means an alleviation of symptoms associated with a disease, disorder or condition, or halt of further progression or worsening of those symptoms. Depending on the disease and condition of the patient, the term “treatment” as used herein may include one or more of curative, palliative and prophylactic treatment. Treatment can also include administering a pharmaceutical formulation of the present invention in combination with other therapies.

The term “therapeutically-effective” indicates the capability of an agent to prevent, or improve the severity of, the disorder. The phrase “therapeutically-effective” is to be understood to be equivalent to the phrase “effective for the treatment, prevention, or amelioration”, and both are intended to qualify the amount of an agent—which will achieve the goal of improvement in the severity of cancer, cardiovascular disease, or pain and inflammation and the frequency of incidence over treatment of each agent by itself.

“Pharmaceutically acceptable” means suitable for use in mammals, companion animals or livestock animals.

If substituents are described as being “independently selected” from a group, each substituent is selected independent of the other. Each substituent therefore may be identical to or different from the other substituent(s).

Compounds of the invention that have the same molecular formula but differ in the nature or sequence of bonding of their atoms or the arrangement of their atoms in space are termed “isomers”. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers”. It will be appreciated by those skilled in the art that the compound of structure I or II can exist as cis- and trans-achiral diastereomers.

Included within the scope of the described compounds are all isomers (e.g., cis-, trans-, or diastereomers) of the compounds described herein alone as well as any mixtures. All of these forms, including enantiomers, diastereomers, cis, trans, syn, anti, solvates (including hydrates), tautomers, and mixtures thereof, are included in the described compounds. Stereoisomeric mixtures, e.g., mixtures of diastereomers, can be separated into their corresponding isomers in a known manner by means of suitable separation methods. Diastereomeric mixtures for example may be separated into their individual diastereomers by means of fractionated crystallization, chromatography, solvent distribution, and similar procedures. This separation may take place either at the level of one of the starting compounds or in a compound of structure I or II itself. Enantiomers may be separated through the formation of diastereomeric salts, for example by salt formation with an enantiomer-pure chiral acid, or by means of chromatography, for example by HPLC, using chromatographic substrates with chiral ligands. The present invention includes all pharmaceutically acceptable isotopically-labelled compounds of structure I or II wherein one or more atoms are replaced by atoms having the same atomic number, but an atomic mass or mass number different from the atomic mass or mass number which predominates in nature.

Examples of isotopes suitable for inclusion in the compounds of the invention include isotopes of hydrogen, such as ²H and ³H, carbon, such as ¹¹C, ¹³C and ¹⁴C, chlorine, such as ³⁶Cl, fluorine, such as ¹⁸F, iodine, such as ¹²³I and ¹²⁵I, nitrogen, such as ¹³N and ¹⁵N, oxygen, such as ¹⁵O, ¹⁷O and ¹⁸O, phosphorus, such as ³²P, and sulphur, such as ³⁵S.

Certain isotopically-labelled compounds of structure I or II, for example, those incorporating a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. The radioactive isotopes tritium, i.e., ³H, and carbon-14, i.e., ¹⁴C, are particularly useful for this purpose in view of their ease of incorporation and ready means of detection.

Substitution with heavier isotopes such as deuterium, i.e., ²H, may afford certain therapeutic advantages resulting from greater metabolic stability, for example, increased in vivo half-life or reduced dosage requirements, and hence may be preferred in some circumstances. Substitution with positron emitting isotopes, such as 11C, 18F, ¹⁵O and ¹³N, can be useful in Positron Emission Topography (PET) studies for examining substrate receptor occupancy. Isotopically-labeled compounds of structure I or II can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples and Preparations using an appropriate isotopically-labeled reagent in place of the non-labeled reagent previously employed.

In therapeutic use for treating disorders in a mammal, a compound of the present invention or its pharmaceutical compositions can be administered orally, parenterally, topically, rectally, transmucosally, or intestinally. Parenteral administrations include indirect injections to generate a systemic effect or direct injections to the afflicted area. Topical administrations include the treatment of skin or organs readily accessible by local application, for example, eyes or ears. It also includes transdermal delivery to generate a systemic effect. The rectal administration includes the form of suppositories. The preferred routes of administration are oral and parenteral.

Pharmaceutically acceptable salts of the compounds of structure I or II include the acid addition and base salts thereof. Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include the acetate, adipate, aspartate, benzoate, besylate, bicarbonate/carbonate, bisulfate/sulfate, borate, camsylate, citrate, cyclamate, edisylate, esylate, formate, fumarate, gluceptate, gluconate, glucuronate, hexafluorophosphate, hibenzate, hydrochloride/chloride, hydrobromide/bromide, hydroiodide/iodide, isethionate, lactate, malate, maleate, malonate, mesylate, methylsulfate, naphthylate, 2-napsylate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate/hydrogen phosphate/dihydrogen phosphate, pyroglutamate, saccharate, stearate, succinate, tannate, tartrate, tosylate, trifluoroacetate and xinofoate salts.

Suitable base salts are formed from bases which form non-toxic salts. Examples include the aluminium, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts.

Hemisalts of acids and bases may also be formed, for example, hemisulfate and hemicalcium salts. For a review on suitable salts, see Handbook of Pharmaceutical Salts: Properties, Selection, and Use by Stahl and Wermuth (Wiley-VCH, 2002).

Pharmaceutically acceptable salts of compounds of structure I or II may be prepared, respectively, by one or more of three methods: (i) by reacting the compound of structure I or II with the desired acid or base; (ii) by removing an acid- or base-labile protecting group from a suitable precursor of the compound of structure I or II or by ring-opening a suitable cyclic precursor, for example, a lactone or lactam, using the desired acid or base; or (iii) by converting one salt of the compound of structure I or II to another by reaction with an appropriate acid or base or by means of a suitable ion exchange column. All three reactions are typically carried out in solution. The resulting salt may precipitate out and be collected by filtration or may be recovered by evaporation of the solvent. The degree of ionization in the resulting salt may vary from completely ionized to almost non-ionized.

Pharmaceutical compositions of the present invention may be manufactured by methods well known in the art, e.g., by means of conventional mixing, dissolving, granulation, dragee-making, levigating, emulsifying, encapsulating, entrapping, lyophilizing processes or spray drying.

Pharmaceutical compositions for use in accordance with the present invention may be formulated in conventional manner using one or more pharmaceutically acceptable carriers comprising excipients and auxiliaries, which facilitate processing of the active compound into preparations, which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen. Pharmaceutically acceptable excipients and carriers are generally known to those skilled in the art and are thus included in the instant invention. Such excipients and carriers are described, for example, in Remington's Pharmaceutical Sciences, Mack Pub. Co., New Jersey (1991). The formulations of the invention can be designed to be short-acting, fast-releasing, long-acting, and sustained-releasing. Thus, the pharmaceutical formulations can also be formulated for controlled release or for slow release.

Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredients are contained in an amount sufficient to achieve the intended purpose, i.e., control or the treatment of disorders or diseases. More specifically, a therapeutically effective amount means an amount of compound effective to prevent, alleviate or ameliorate symptoms/signs of disease or prolong the survival of the subject being treated.

The quantity of active component, which is the compound of this invention, in the pharmaceutical composition and unit dosage form thereof, may be varied or adjusted widely depending upon the manner of administration, the potency of the particular compound and the desired concentration. Determination of a therapeutically effective amount is well within the capability of those skilled in the art. Generally, the quantity of active component will range between 0.01% to 99% by weight of the composition.

Generally, a therapeutically effective amount of dosage of active component will be in the range of about 0.01 to about 100 mg/kg of body weight/day, preferably about 0.1 to about 10 mg/kg of body weight/day, more preferably about 0.3 to 3 mg/kg of body weight/day, even more preferably about 0.3 to 1.5 mg/kg of body weight/day It is to be understood that the dosages may vary depending upon the requirements of each subject and the severity of the disorders or diseases being treated.

The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as two, three, four or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations; such as multiple inhalations from an insufflator or by application of a plurality of drops into the eye.

Also, it is to be understood that the initial dosage administered may be increased beyond the above upper level in order to rapidly achieve the desired plasma concentration. On the other hand, the initial dosage may be smaller than the optimum and the daily dosage may be progressively increased during the course of treatment depending on the particular situation. If desired, the daily dose may also be divided into multiple doses for administration, e.g., two to four times per day.

In executing the synthesis of the compounds of the invention, one skilled in the art will recognize the need to sample and assay reaction mixtures prior to work up in order to monitor the progress of reactions and decide whether the reaction should be continued or whether it is ready to be worked up to obtain the desired product. Common methods for assaying reaction mixtures include thin-layer chromatography (TLC), liquid chromatography/mass spectroscopy (LCMS), and nuclear magnetic resonance (NMR).

One skilled in the art will also recognize that the compounds of the invention may be prepared as mixtures of diastereomers or geometric isomers (e.g., cis and trans substitution on a cycloalkane ring). These isomers can be separated by standard chromatographic techniques, such as normal phase chromatography on silica gel, reverse phase preparative high pressure liquid chromatography or supercritical fluid chromatography. One skilled in the art will also recognize that some compounds of the invention are chiral and thus may be prepared as racemic or scalemic mixtures of enantiomers. Several methods are available and are well known to those skilled in the art for the separation of enantiomers. A preferred method for the routine separation enantiomers is supercritical fluid chromatography employing a chiral stationary phase.

Experimental Section

Except where otherwise noted, reactions were run under an atmosphere of nitrogen. Chromatography on silica gel was carried out using 250-400 mesh silica gel using pressurized nitrogen (˜10-15 psi) to drive solvent through the column (“flash chromatography”). Where indicated, solutions and reaction mixtures were concentrated by rotary evaporation under vacuum.

¹H Nuclear magnetic resonance (NMR) spectra were in all cases consistent with the proposed structures. Characteristic chemical shifts (δ) are given in parts-per-million downfield from tetramethylsilane using conventional abbreviations for designation of major peaks: e.g. s, singlet; d, doublet; t, triplet; q, quartet; m, multiplet; br, broad. The following abbreviations have been used for common NMR solvents: CD₃CN, deuteroacetonitrile; CDCl₃, deuterochloroform; DMSO-d₆, deuterodimethylsulfoxide; and CD₃OD, deuteromethanol. Where appropriate, tautomers may be recorded within the NMR data; and some exchangeable protons may not be visible.

Mass spectra were recorded using electron impact ionization (El), electrospray ionisation (ESI) or atmospheric pressure chemical ionisation (APCI). The observed ions are reported as MS m/z and may be positive ions of the compound [M]⁺, compound plus a proton [MH]⁺, or compound plus a sodium ion [MNa]⁺. In some cases the only observed ions may be fragment ions reported as [MH-(fragment lost)]⁺. Where relevant, the reported ions are assigned for isotopes of chlorine (³⁵Cl and/or ³⁷Cl), bromine (⁷⁹Br and/or ⁸¹Br) and tin (¹²⁹Sn).

Biological Evaluation

Compounds of the invention were evaluated by in vitro methods to determine their respective ability to inhibit the JAK kinases (TYK2, JAK1, JAK2, JAK3).

Assay Format

The human JAK inhibitory activity was determined by using a microfluidic assay to monitor phosphorylation of a synthetic peptide by the recombinant human kinase domain of each of the four members of the JAK family, JAK1, JAK2, JAK3 and TYK2. Reaction mixtures contained 1 μM of a fluorescently labeled synthetic peptide, a concentration less than the apparent K_m, and 1 mM ATP. Each assay condition was optimized for enzyme concentration and room temperature incubation time to obtain a conversion rate of 20% to 30% phosphorylated peptide product. Reactions were terminated by the addition of stop buffer containing EDTA. Utilizing the LabChip 3000 mobility shift technology (Caliper Life Science), each assay reaction was sampled to determine the level of phosphorylation. This technology is separation-based, allowing direct detection of fluorescently labeled substrates and products. Separations are controlled by a combination of vacuum pressure and electric field strength optimized for each peptide substrate.

Assay Protocol

JAK Caliper Enzyme Assay at 1mM ATP

Compounds were added to a 384-well plate. Reaction mixtures contained 10 mM HEPES, pH 7.4, 10 mM MgCl₂, 0.01% BSA, 0.0005% Tween 20, 1 mM ATP and 1 μM peptide substrate. The JAK1 and TYK2 assays contained 1 μM of the IRStide peptide (5FAM-KKSRGDYMTMQID) and the JAK2 and JAK3 assays contained 1 μM of the JAKtide peptide (FITC-KGGEEEEYFELVKK). The assays were initiated by the addition of 20 nM JAK1, 1 nM JAK2, 1 nM JAK or 1 nM TYK2 enzyme and were incubated at room temperature for three hours for JAK1, 60 minutes for JAK2, 75 minutes for JAK3 or 135 minutes for TYK2. Enzyme concentrations and incubation times were optimized for each new enzyme preps and were modified slightly over time to ensure 20% to 30% phosphorylation. The assays were stopped with 15 μL of 180 mM HEPES, pH 7.4, 20 mM EDTA, and 0.2% Coating Reagent 3. The assay plates were placed on a Caliper Life Science LC3000 instrument, and each well was sampled using appropriate separation conditions to measure the unphosphorylated and phosphorylated peptide.

Data Analysis

The data was collected using the HTS Well Analyzer software from Caliper Life Sciences. The data output for data analysis is the percent product converted calculated on peak height (Equation 1).

% product converted=100*((product)/(product+substrate))   Equation 1:

The percent effect at each compound concentration was calculated based on the positive and negative control well contained within each assay plate (Equation 2). The positive control wells contained a saturating concentration of a control compound that produced a level of phosphorylation comparable to background (i.e., completely inhibited JAK1, JAK2, JAK3 or TYK2). The negative control wells contained DMSO alone (at the same concentration as the compound wells) that was used to set the baseline activity in the assay (i.e., uninhibited JAK1, JAK2, JAK3 or TYK2).

% effect=100*((sample well negative control)/(positive control-negative control))   Equation 2:

The percent effect was plotted against the compound concentration compound.

An unconstrained sigmoid curve was fitted using a 4 parameter logistic model and the compound concentration required for 50% inhibition (IC₅₀) was determined (Equation 3).

y=((max-min)/(1+((x/IC₅₀){circumflex over ( )}s)))+min   Equation 3:

where max is the maximum asymptote (complete inhibition), min is the minimum asymptote (no inhibition) and s is the slope factor. IC₅₀ values are reported in nM for each compound:

Selected compounds were assessed for their ability to inhibit IL-12 signaling in a human whole blood flow cytometry assay. IL-12 signals through TYK2 and JAK2.

Human Whole Blood IL-12 Induced STAT4 Phosphorylation Assay

Test articles were prepared as 30 mM stocks in DMSO. An 11-point 2.5 dilution series was created in DMSO with a top concentration of 10 mM. Further dilution was done by adding 4 μL of the above test article solutions into 96 μL of PBS with a top concentration of 400 μM. Human whole blood was collected from healthy donors via vein puncture into Vacutainer collection tubes containing sodium heparin (Catalog No. 366480; Becton Dickinson, Franklin Lakes, N.J.). Blood was warmed to 37° C. prior to use. Human whole blood was aliquoted (90 mL/well) in 96-well, deep-well, V-bottom plates and treated with compounds at 11 different concentrations (0.2% DMSO final) at 37° C. for 60 minutes. This was followed by a challenge with IL-12 (5 mL/well; final, 5 ng/mL) for 15 minutes. Samples were treated with warm 1× Lyse/Fix buffer (700 mL/well) to terminate activation and further incubated at 37° C. for 20 minutes to lyse red blood cells. Plates were centrifuged at 300×g for 5 minutes, supernatant was aspirated, and cells were washed with 800 mL per well of staining buffer (PBS containing 0.5% fetal bovine serum and 0.01% sodium azide). The washed cell pellets were resuspended with 350 mL/well of pre-chilled 90% methanol, and incubated at 4° C. for 30 minutes. Plates were centrifuged at 300×g for 5 minutes, supernatant containing 90% methanol was aspirated, and cells were washed with 800 mL /well of staining buffer. Cell pellets were resuspended in staining buffer containing anti-pSTAT4-AlexaFluor647 (1 to 150 dilution, 150 mL/well), and incubated at room temperature in the dark overnight.

Samples were transferred to 96-well U-bottom plates and flow cytometric analysis was performed on a FACSCalibur or LSRFortessa equipped with a HTS plate loader (BD Biosciences). The lymphocyte population was gated for histogram analysis of pSTAT4. Background fluorescence was defined using unstimulated cells and a gate was placed at the foot of the peak to include ˜0.5% gated population. The histogram statistical analysis was performed using CellQuestÔ Pro version 5.2.1 (BD Biosciences) or FACSDiva version 6.2 (BD Biosciences) software. Relative fluorescence unit (RFU), which measures the level of phospho STAT4, was calculated by multiplying the percent positive population and its mean fluorescence. Data from 11 compound concentrations (singlicate at each concentration) was normalized as a percentage of control based on the formula:

% of Control=100'(A−B)/(C−B)

where A is the RFU from wells containing compound and IL-12, B is the RFU from wells without IL-12 and compound (minimum fluorescence) and C is the RFU from wells containing only IL-12 (maximum fluorescence). Inhibition curves and IC₅₀ values were determined using the Prism version 5 software (GraphPad, La Jolla, Calif.).
