COMPOUNDS AND METHODS FOR THE TARGETED DEGRADATION OF IRAK-4

This application relates to a bifunctional compound having the structure of Formula (I):

Description

BACKGROUND

Most small molecule drugs bind enzymes or receptors in tight and well-defined pockets. On the other hand, protein-protein interactions are notoriously difficult to target using small molecules due to their large contact surfaces and the shallow grooves or flat interfaces involved. E3 ubiquitin ligases (of which hundreds are known in humans) confer substrate specificity for ubiquitination, and therefore are more attractive therapeutic targets than general proteasome inhibitors due to their specificity for certain protein substrates. The development of ligands of E3 ligases has proven challenging, in part because they must disrupt protein-protein interactions. However, notable developments have provided specific ligands which bind to these ligases. For example, since the discovery of nutlins, the first small molecule E3 ligase inhibitors, additional compounds have been reported that target E3 ligases.

Cereblon is a protein that in humans is encoded by the CRBN gene. CRBN orthologs are highly conserved from plants to humans, which underscores its physiological importance. Cereblon forms an E3 ubiquitin ligase complex with damaged DNA binding protein 1 (DDB1), Cullin-4A (CUL4A), and regulator of cullins 1 (ROC 1). This complex ubiquitinates several other proteins. Through a mechanism which has not been completely elucidated, cereblon ubiquitination of target proteins results in increased levels of fibroblast growth factor 8 (FGF8) and fibroblast growth factor 10 (FGF10). FGF8 in turn regulates several developmental processes, such as limb and auditory vesicle formation. The net result is that this ubiquitin ligase complex is important for limb outgrowth in embryos. In the absence of cereblon, DDB1 forms a complex with DDB2 that functions as a DNA damage-binding protein.

Interleukin-1 (IL-1) Receptor-Associated Kinase-4 (IRAK-4) is a serine/threonine kinase enzyme that plays an essential role in signal transduction by Toll/IL-1 receptors (TIRs). Diverse IRAK enzymes are key components in the signal transduction pathways mediated by interleukin-1 receptor (IL-1R) and Toll-like receptors (TLRs) (Janssens, S, et al. Mol. Cell. 11(2), 2003, 293-302). There are four members in the mammalian IRAK family: IRAK-1, IRAK-2, IRAK-3, and IRAK-4. These proteins are characterized by a typical N-terminal death domain that mediates interaction with MyD88-family adaptor proteins and a centrally located kinase domain. Upon recruitment of MyD88 and IRAK-4 to the Toll-interleukin domain, activation leads to phosphorylation of IRAK-1 and/or IRAK-2 leading to engagement of TRAF6. Subsequent signaling results in activation of NF-κB and the release of various cytokines and chemokines. The MYD88 L265P mutation occurring in 91% Waldenstrom's macroglobulinemia, 29% ABC DLBCL, 9% MALT lymphomas, and 3% CLL coordinates a constitutively active signalosome in which IRAK-4-mediated phosphorylation of IRAK-1 promotes the assembly of additional signaling proteins driving survival in these cancers.

The IRAK proteins, as well as MyD88, have been shown to play a role in transducing signals other than those originating from IL-1R receptors, including signals triggered by activation of IL-18 receptors (Kanakaraj, et al. J. Exp. Med. 189(7), 1999, 1129-38) and LPS receptors (Yang, et al., J. Immunol. 163(2), 1999, 639-43). Out of the four members in the mammalian IRAK family, IRAK-4 is the “master IRAK”. Under overexpression conditions, all IRAKs can mediate the activation of nuclear factor-KB (NF-κB) and stress-induced mitogen activated protein kinase (MAPK)-signaling cascades. However, only IRAK-1 and IRAK-4 have been shown to have active kinase activity. While IRAK-1 kinase activity could be dispensable for its function in IL-1-induced NF-κB activation (Kanakaraj et al, J. Exp. Med. 187(12), 1998, 2073-9; and Li, et al. Mol. Cell. Biol. 19(7), 1999, 4643-52), IRAK-4 requires its kinase activity for signal transduction (Li S, et al. Proc. Natl. Acad. Sci. USA 99(8), 2002, 5567-72; and Lye, E. et al, J. Biol. Chem. 279(39); 2004, 40653-8). Given the central role of IRAK-4 in Toll-like/IL-1R signaling and immunological protection, IRAK-4 inhibitors have been identified as potentially valuable therapeutics in inflammatory diseases, sepsis and autoimmune disorders (Wietek C, et al, Mol. Interv. 2: 2002, 212-5). Since IRAK-4 possesses scaffolding as well as kinase-dependent signaling activity (Lee K L, Ambler C M, Anderson D R, et al. J Med Chem. 2017; 60(13):5521-42), degradation of IRAK-4 may be a valuable alternative to inhibition by small molecules.

Mice lacking IRAK-4 are viable and show complete abrogation of inflammatory cytokine production in response to IL-1, IL-18 or LPS (Suzuki et al. Nature, 416(6882), 2002, 750-6). Human patients lacking IRAK-4 are severely immunocompromised and are not responsive to these cytokines (Medvedev et al. J. Exp. Med., 198(4), 2003, 521-31; and Picard et al. Science 299(5615), 2003, 2076-9). Knock-in mice containing inactive IRAK-4 were completely resistant to lipopolysaccharide- and CpG-induced shock (Kim T W, et al. J. Exp. Med 204(5), 2007, 1025-36; and Kawagoe T, et al. J. Exp. Med. 204(5): 2007, 1013-24) and illustrated that IRAK-4 kinase activity is essential for cytokine production, activation of MAPKs and induction of NF-κB regulated genes in response to TLR ligands (Koziczak-Holbro M, et al. J. Biol. Chem. 282(18): 2007, 13552-60). Inactivation of IRAK-4 kinase (IRAK-4 KI) in mice leads to resistance to EAE due to reduction in infiltrating inflammatory cells into CNS and reduced antigen specific CD4+ T-cell mediated IL-17 production (Staschke et al. The Journal of Immunology, 183(1), 2009, 568-77).

Bifunctional compounds, such as those described in U.S. Patent Application Publication Nos. 2015/0291562 and 2014/0356322 (both incorporated herein by reference), function to recruit endogenous proteins to an E3 ubiquitin ligase for ubiquitination and degradation. In particular, the publications describe bifunctional or proteolysis targeting chimeric compounds (PROTAC® protein degraders), which find utility as modulators of targeted ubiquitination of a variety of polypeptides and proteins, which are then degraded via the proteasome system.

An ongoing need exists in the art for effective treatments for disease associated signaling cascades mediated by IRAK-4. However, non-specific effects, and the inability to effectively target both the kinase and scaffolding roles of IRAK-4, remain as obstacles to the development of effective treatments. As such, small-molecule therapeutic agents that target IRAK-4 and that leverage protein degradation via the ubiquitin proteasome system would be useful.

BRIEF DESCRIPTION OF THE DRAWINGS

FIGS. 1A and 1B. Illustration of general principle for PROTAC function. (1A) Exemplary PROTACs comprise a protein targeting moiety (PTM; darkly shaded rectangle), a ubiquitin ligase binding moiety (ULM; lightly shaded triangle), and optionally a linker moiety (L; black line) coupling or tethering the PTM to the ULM. (1B) Illustrates the functional use of the PROTACs as described herein. Briefly, the ULM recognizes and binds to a specific E3 ubiquitin ligase, and the PTM binds and recruits a target protein bringing it into close proximity to the E3 ubiquitin ligase. Typically, the E3 ubiquitin ligase is complexed with an E2 ubiquitin conjugating protein, and either alone or via the E2 protein catalyzes attachment of ubiquitin (dark circles) to a lysine on the target protein via an isopeptide bond. The poly-ubiquitinated protein (far right) is then targeted for degradation by the proteasomal machinery of the cell.

The effect can be detected by any assay or other detection method known in the art. As used herein, “therapeutically effective amount” can mean that amount necessary to make a clinically observed improvement in the patient. In some embodiments, the composition is formulated such that it comprises an amount that would not cause one or more unwanted side effects. A therapeutically effective amount of a pharmaceutical agent can also mean that amount which provides an objectively identifiable improvement as noted by a clinician or other qualified observer. The precise therapeutically effective amount for a subject will depend upon the subject's age, gender, body weight, size, and health; the nature and extent of the condition; and therapeutic or combination of therapeutics selected for administration.

Glidants include, but are not limited to, silicon dioxide, colloidal silicon dioxide, calcium silicate, magnesium silicate, magnesium trisilicate, talc, starch, mixtures thereof, and the like.

The terms “haloalkyl”, “haloalkenyl”, or “haloalkynyl”, as used herein refer to an alkyl, alkenyl or alkynyl, including straight-chain and branched, that is substituted with one or more halogens or halo groups. Examples of haloalkyl include but are not limited to CF₃, CH₂CF₃, and CCl₃.

The terms “hal”, “halo”, or “halogen”, as used herein, refer to an atom selected from the group consisting of fluorine, chlorine, bromine, and iodine.

The term “heteroaryl”, as used herein, refers to a mono- or poly-cyclic (e.g., bi-, or tri-cyclic or more) fused or non-fused, radical or ring system having at least one aromatic ring, having from five to twelve ring atoms of which at least one ring atom is selected from the group consisting of S, O, P, and N. In other words, heteroaryl is aryl containing at least one heteroatom. Examples of heteroaryl include, but are not limited to, pyridinyl, furanyl, thiazolyl, imidazolyl, indolyl, benzofuranyl, and the like.

The term “5- or 6-membered heteroaryl”, is taken to mean a ring having five or six ring atoms of which at least one ring atom is selected from the group consisting of S, O, P, and N. Heteroaryl includes, but is not limited to, pyridinyl, pyrazinyl, pyrimidinyl, pyrrolyl, pyrazolyl, imidazolyl, thiazolyl, oxazolyl, isooxazolyl, thiadiazolyl, oxadiazolyl, thiophenyl, furanyl, quinolinyl, isoquinolinyl, benzimidazolyl, benzooxazolyl, quinoxalinyl, and the like.

“Heterocyclyl” or “heterocycloalkyl”, as used herein, are cyclic systems containing carbon and at least one heteroatom selected from N, O, S, and P, wherein there is not delocalized π electrons (aromaticity) shared among the ring carbon or heteroatoms, i.e., the cyclic ring system in non-aromatic. The heterocycloalkyl ring structure may be substituted by one or more substituents. The substituents can themselves be optionally substituted. Examples of heterocyclyl rings include, but are not limited to, oxetanyl, azetidinyl, tetrahydrofuranyl, tetrahydropyranyl, pyrrolidinyl, oxazolinyl, oxazolidinyl, thiazolinyl, thiazolidinyl, pyranyl, thiopyranyl, tetrahydropyranyl, dioxalinyl, piperidinyl, morpholinyl, thiomorpholinyl, thiomorpholinyl S-oxide, thiomorpholinyl S-dioxide, piperazinyl, azepinyl, oxepinyl, diazepinyl, tropanyl, oxazolidinonyl, and homotropanyl.

The term “independently selected” is used herein to indicate that, for a variable which occurs in more than one location in a genus, the identity of the variable is determined separately in each instance. For example, if R^x appears as a substituent on two different atoms, the two instances of R^x may be the same moiety, or different moieties. The same is true if a single atom is substituted with more than one instance of R^x. The identity of R^x in each instance is determined independently of the identity of the other(s).

“Isomers” mean any compound having an identical molecular formula but differing in the nature or sequence of bonding of their atoms or in the arrangement of their atoms in space. Isomers that differ in the arrangement of their atoms in space are termed “stereoisomers.” Stereoisomers that are not mirror images of one another are termed “diastereomers” and stereoisomers that are nonsuperimposable mirror images are termed “enantiomers” or sometimes “optical isomers.” A carbon atom bonded to four nonidentical substituents is termed a “chiral center.” A compound with one chiral center has two enantiomeric forms of opposite chirality. A mixture of the two enantiomeric forms is termed a “racemic mixture.” A compound that has more than one chiral center has 2n-1 enantiomeric pairs, where n is the number of chiral centers. Compounds with more than one chiral center may exist as either an individual diastereomer or as a mixture of diastereomers, termed a “diastereomeric mixture.” When one chiral center is present a stereoisomer may be characterized by the absolute configuration of that chiral center. Absolute configuration refers to the arrangement in space of the substituents attached to the chiral center. Enantiomers are characterized by the absolute configuration of their chiral centers and described by the R- and S-sequencing rules of Cahn, Ingold and Prelog. Conventions for stereochemical nomenclature, methods for the determination of stereochemistry and the separation of stereoisomers are well known in the art (e.g., see “Advanced Organic Chemistry”, 4th edition, March, Jerry, John Wiley & Sons, New York, 1992). The compounds of Formula (I) may contain asymmetric or chiral centers and, therefore, exist in different stereoisomeric forms. It is intended, unless specified otherwise, that all stereoisomeric forms of the compounds of Formula (I) as well as mixtures thereof, including racemic mixtures, form part of the present invention. In addition, the present invention embraces all geometric and positional isomers (including cis and trans-forms), as well as mixtures thereof, are embraced within the scope of the invention. In general, a reference to a compound is intended to cover its stereoisomers and mixture of various stereoisomers.

The present disclosure is intended to include all isotopes of atoms occurring in the present compounds. Isotopes include those atoms having the same atomic number but different mass numbers. In particular, one, some, or all hydrogens may be deuterium. Radioactive isotopes may be used, for instance for structural analysis or to facilitate tracing the fate of the compounds or their metabolic products after administration. By way of general example and without limitation, isotopes of hydrogen include deuterium and tritium and isotopes of carbon include ¹³C and ¹⁴C.

The term “isotopic derivative” includes derivatives of compounds in which one or more atoms in the compounds are replaced with corresponding isotopes of the atoms. For example, an isotopic derivative of a compound containing a carbon atom (C¹²) would be one in which one or more of the carbon atoms of the compound are replaced with the C¹³ isotope(s).

Lubricants include, but are not limited to, calcium stearate, glyceryl monostearate, glyceryl behenate, glyceryl palmitostearate, hexagonal boron nitride, hydrogenated vegetable oil, light mineral oil, magnesium stearate, mineral oil, polyethylene glycol, poloxamer, sodium benzoate, sodium lauryl sulfate, sodium stearyl fumarate, stearic acid, talc, zinc stearate, mixtures thereof, and the like.

Suitable forms for oral administration may include one or more pharmaceutically acceptable excipients, including, for example, carriers, fillers, surfactants, diluents, buffers, sweeteners, disintegrants, binders, lubricants, glidants, colorants, flavors, stabilizing agents, coatings, or any mixtures thereof.

A “pharmaceutical composition” is a formulation containing one or more therapeutic agents (e.g., one or more compounds of the present disclosure) in a form suitable for administration to a subject. In one embodiment, the pharmaceutical composition is in bulk form, e.g., for storage. Alternatively, the pharmaceutical composition is in unit dosage form. It can be advantageous to formulate compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active reagent calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The specifications for the dosage unit forms of the invention are dictated by and directly dependent on the unique characteristics of the active agents and the particular therapeutic effect to be achieved, and the limitations in the art of compounding such an active agent for the treatment of individuals.

A compound of the present disclosure may be administered in the form of a pharmaceutical composition comprising a pharmaceutically acceptable excipient. The formulation may be adapted for administration by any of a variety of routes including oral, buccal, rectal, vaginal, intranasal, intraocular, transdermal, subcutaneous, intravenous, or intramuscular.

The term “pharmaceutical” or “pharmaceutically acceptable” when used herein as an adjective, means substantially non-toxic and substantially non-deleterious to the recipient. As used herein, the phrase “pharmaceutically acceptable” refers to those compounds, materials, compositions, carriers, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio.

“Pharmaceutically acceptable carrier or excipient” means a carrier or excipient that is useful in preparing a pharmaceutical composition that is generally safe, non-toxic and neither biologically nor otherwise undesirable, and includes any excipient that is acceptable for veterinary use and/or human pharmaceutical use. A “pharmaceutically acceptable excipient” as used herein includes both one and more than one such excipient.

As used herein, “pharmaceutically acceptable salts” can refer to derivatives of the compounds of the present disclosure wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines, alkali or organic salts of acidic residues such as carboxylic acids, and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from non-toxic inorganic or organic acids. For example, such conventional non-toxic salts include, but are not limited to, those derived from inorganic and organic acids selected from 2-acetoxybenzoic, 2-hydroxyethane sulfonic, acetic, ascorbic, benzene sulfonic, benzoic, bicarbonic, carbonic, citric, edetic, ethane disulfonic, 1,2-ethane sulfonic, fumaric, glucoheptonic, gluconic, glutamic, glycolic, glycollyarsanilic, hexylresorcinic, hydrabamic, hydrobromic, hydrochloric, hydroiodic, hydroxymaleic, hydroxynaphthoic, isethionic, lactic, lactobionic, lauryl sulfonic, maleic, malic, mandelic, methane sulfonic, napsylic, nitric, oxalic, pamoic, pantothenic, phenylacetic, phosphoric, polygalacturonic, propionic, salicyclic, stearic, subacetic, succinic, sulfamic, sulfanilic, sulfuric, tannic, tartaric, toluene sulfonic, and the commonly occurring amine acids, e.g., glycine, alanine, phenylalanine, arginine, etc.

Other examples of pharmaceutically acceptable salts can include hexanoic acid, cyclopentane propionic acid, pyruvic acid, malonic acid, 3-(4-hydroxybenzoyl)benzoic acid, cinnamic acid, 4-chlorobenzenesulfonic acid, 2-naphthalenesulfonic acid, 4-toluenesulfonic acid, camphorsulfonic acid, 4-methylbicyclo-[2.2.2]-oct-2-ene-1-carboxylic acid, 3-phenylpropionic acid, trimethylacetic acid, tertiary butylacetic acid, muconic acid, and the like. The present disclosure also encompasses salts formed when an acidic proton present in the parent compound either is replaced by a metal ion, e.g., an alkali metal ion, or an alkaline earth metal ion, e.g., an aluminum ion; or coordinates with an organic base such as ethanolamine, diethanolamine, triethanolamine, tromethamine, N-methylglucamine, diethylamine, diethylaminoethanol, ethylenediamine, imidazole, lysine, arginine, morpholine, 2-hydroxyethylmorpholine, dibenzylethylenediamine, trimethylamine, piperidinyl, pyrrolidine, benzylamine, tetramethylammonium hydroxide and the like.

It should be understood that all references to pharmaceutically acceptable salts include solvent addition forms (solvates) or crystal forms (polymorphs) as defined herein, of the same salt.

Additionally, the compounds of the present disclosure, for example, the salts of the compounds, can exist in either hydrated or unhydrated (the anhydrous) form or as solvates with other solvent molecules. Nonlimiting examples of hydrates include monohydrates, dihydrates, etc. Nonlimiting examples of solvates include ethanol solvates, acetone solvates, etc.

Some of the compounds of the present disclosure may exist in unsolvated as well as solvated forms such as, for example, hydrates.

“Solvate” means a solvent addition form that contains either a stoichiometric or non-stoichiometric amounts of solvent. Some compounds can have a tendency to trap a fixed molar ratio of solvent molecules in the crystalline solid state, thus forming a solvate. If the solvent is water the solvate formed is a hydrate, when the solvent is alcohol, the solvate formed is an alcoholate. Hydrates are formed by the combination of one or more molecules of water with one of the substances in which the water retains its molecular state as H₂O, such combination being able to form one or more hydrate. In the hydrates, the water molecules are attached through secondary valencies by intermolecular forces, in particular hydrogen bridges. Solid hydrates contain water as so-called crystal water in stoichiometric ratios, where the water molecules do not have to be equivalent with respect to their binding state. Examples of hydrates are sesquihydrates, monohydrates, dihydrates or trihydrates. Also suitable are the hydrates of salts of the compounds of the disclosure.

“Spirocycloalkyl” or “spirocyclyl” means carbogenic bicyclic ring systems with both rings connected through a single atom. The ring can be different in size and nature, or identical in size and nature. Examples include spiropentane, spriohexane, spiroheptane, spirooctane, spirononane, or spirodecane. One or both of the rings in a spirocycle can be fused to another ring carbocyclic, heterocyclic, aromatic, or heteroaromatic ring. One or more of the carbon atoms in the spirocycle can be substituted with a heteroatom (e.g., O, N, S, or P). A (C₃-C₁₂) spirocycloalkyl is a spirocycle containing from 3 to 12 carbon atoms.

It will be appreciated that the compounds, as described herein, may be substituted with one, two, three, four, five or more (up to the total possible number of substitutents for the particular compound) independently selected substituents or functional moieties. In general, the term “substituted” whether preceded by the term “optionally” or not, and substituents contained in formulas disclosed herein, refer to the replacement of hydrogen radicals in a given structure with the radical of a specified substituent. When more than one position in any given structure is substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at each position. As used herein, the term “substituted” is contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, aromatic and nonaromatic substituents of organic compounds. For purposes of this disclosure, heteroatoms such as nitrogen may have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valencies of the heteroatoms. The nitrogen and sulfur heteroatoms may optionally be oxidized, and the nitrogen heteroatom may optionally be quaternized. Examples of substituents on the moieties disclosed herein (e.g., alkyl, alkenyl, alkynyl, alkoxy, aryl, heteroaryl, cycloalkyl, cycloalkenyl, non-aromatic heterocycle groups) include, but are not limited to, alkenyl, alkynyl, halogen, haloalkyl, alkoxy, alkylthio, alkylsulfinyl, alkylsulfonyl, heteroaryl, aryl, cycloalkyl, cycloalkenyl, non-aromatic heterocycle, hydroxyl, carbamoyl, oxo, amino, nitro, azido, -SH, and -CN.

As described herein, compounds of the disclosure may optionally be substituted with one or more substituents, such as those described generally above, or as exemplified by particular classes, subclasses, and species of the disclosure. It will be appreciated that the phrase “optionally substituted” is used interchangeably with the phrase “substituted or unsubstituted.” Unless otherwise indicated, an optionally substituted group may have a substituent at any or each substitutable position of the group, and when more than one position in any given structure is substituted with more than one substituent independently selected from a specified group, the substituent may be either the same or different at each substituted every position.

The pharmaceutical compositions containing a bifunctional compound of Formula (I) may be manufactured in a manner that is generally known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping, or lyophilizing processes. Pharmaceutical compositions may be formulated in a conventional manner using one or more pharmaceutically acceptable carriers comprising excipients and/or auxiliaries that facilitate processing of a compound of Formula (I) into preparations that can be used pharmaceutically. Of course, the appropriate formulation is dependent upon the route of administration chosen.

Pharmaceutical compositions suitable for injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (PBS). In all cases, the composition must be sterile and should be fluid to the extent that easy syringeability exists. It must be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, using a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and/or by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, a controlled release polymer or other material such as aluminum monostearate or gelatin.

Sterile injectable solutions can be prepared by incorporating a compound of Formula (I) in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active agent or compound into a sterile vehicle that contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation are vacuum drying and freeze-drying that yield a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Oral compositions generally include an inert diluent or an edible pharmaceutically acceptable carrier. They can be enclosed in gelatin capsules or compressed into tablets. For oral therapeutic administration, a bifunctional compound of Formula (I) can be incorporated with excipients and used in the form of tablets, troches, or capsules. Oral compositions can also be prepared using a fluid carrier, wherein the agent or compound is administered by the oral route. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or materials of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose; a disintegrating agent such as alginic acid, sodium starch glycolate (Primojel®), or corn starch; a lubricant such as magnesium stearate; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

For administration by inhalation, the agents or compounds may be delivered in the form of an aerosol spray from pressured container or dispenser, which may contain a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer.

Systemic administration can also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants may include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished using nasal sprays, suppositories or sublingual or buccal formulations. For transdermal administration, the active compounds may be formulated into ointments, salves, gels, creams, or transdermal patches.

In one aspect, a bifunctional compound of Formula (I) is prepared with pharmaceutically acceptable carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, an implant, or a microencapsulated delivery system. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid to prepare controlled release or sustained release formulations. Methods for preparation of such formulations will be apparent to those skilled in the art.

Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) can be used as pharmaceutically acceptable carriers. These can be prepared according to methods known in the art, for example, as described in U.S. Pat. No. 4,522,811.

It is especially advantageous to formulate oral or parenteral compositions in unit dosage form for ease of administration, uniformity of dosage, and compliance. Unit dosage form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound determined to produce the desired therapeutic effect in association with the required pharmaceutical carrier. The unit dosage forms of an application are dictated by and directly dependent on several factors, such as, for example, the unique characteristics of a compound of Formula (I) the particular therapeutic effect to be achieved, and the condition of the patient being treated.

Pharmaceutical compositions disclosed herein can be included in a container, pack, or dispenser together with printed instructions for administration.

Illustrative pharmaceutical compositions are tablets and gelatin capsules comprising a bifunctional compound of Formula (I) and a pharmaceutically acceptable carrier, such as a) a diluent, e.g., purified water, triglyceride oils, such as hydrogenated or partially hydrogenated vegetable oil, or mixtures thereof, corn oil, olive oil, sunflower oil, safflower oil, fish oils, such as EPA or DHA, or their esters or triglycerides or mixtures thereof, omega-3 fatty acids or derivatives thereof, lactose, dextrose, sucrose, mannitol, sorbitol, cellulose, sodium, saccharin, glucose and/or glycine; b) a lubricant, e.g., silica, talcum, stearic acid, its magnesium or calcium salt, sodium oleate, sodium stearate, magnesium stearate, sodium benzoate, sodium acetate, sodium chloride and/or polyethylene glycol; c) a binder, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, magnesium carbonate, natural sugars such as glucose or beta-lactose, corn sweeteners, natural and synthetic gums such as acacia, tragacanth or sodium alginate, waxes and/or polyvinylpyrrolidone, if desired; d) a disintegrant, e.g., starches, agar, methyl cellulose, bentonite, xanthan gum, algic acid or its sodium salt, or effervescent mixtures; e) absorbent, colorant, flavorant or sweetener; f) an emulsifier or dispersing agent, such as Tween 80, Labrasol, HPMC, DOSS, caproyl 909, labrafac, labrafil, peceol, transcutol, capmul MCM, capmul PG-12, captex 355, gelucire, vitamin E TGPS or other acceptable emulsifier; and/or g) an agent that enhances absorption of the salt such as cyclodextrin, hydroxypropyl-cyclodextrin, PEG400, and/or PEG200.

For preparing pharmaceutical compositions from a bifunctional compound of Formula (I), pharmaceutically acceptable carriers can be either solid or liquid. Solid form preparations include powders, tablets, dispersible granules, capsules, cachets and suppositories. The powders and tablets may be comprised of from about 5 to about 95 percent active ingredient. Suitable solid carriers are known in the art, e.g., magnesium carbonate, magnesium stearate, talc, sugar, or lactose. Tablets, powders, cachets, and capsules can be used as solid dosage forms suitable for oral administration.

Methods of Ubiquitinating/Degrading a Target Protein in a Cell

The present invention further provides a method of ubiquitinating/degrading a target protein, e.g., IRAK-4 in a cell. The method comprises administering a bifunctional composition comprising an E3 ubiquitin ligase binding moiety and an IRAK-4 protein targeting moiety, preferably linked through a linker moiety, as otherwise described herein, wherein the E3 ubiquitin ligase binding moiety is coupled to the protein targeting moiety and wherein the E3 ubiquitin ligase binding moiety recognizes a ubiquitin pathway protein (e.g., an ubiquitin ligase, preferably an E3 ubiquitin ligase), and the protein targeting moiety recognizes the target protein such that the target protein will be ubiquitinated when the target protein is placed in proximity to the ubiquitin ligase, thus resulting in degradation/inhibition of the target protein and the control of protein levels. The control of protein levels afforded by the present invention provides treatment of a disease state or condition, which is modulated through the target protein by lowering the level of that protein in the cells of a patient.

In one embodiment, the present invention is directed to a method of treating a patient in need thereof for a disease state or condition modulated through the IRAK-4 protein where the degradation of that protein will produce a therapeutic effect in that patient, the method comprising administering to a patient in need thereof an effective amount of a bifunctional compound according to the present invention, optionally in combination with another bioactive agent. The disease state or condition may be a disease caused by a microbial agent or other exogenous agent such as a virus, bacteria, fungus, protozoa, or other microbe, or may be a disease state or condition, causally related to signalling cascades mediated by IRAK-4 protein, which leads to a disease state and/or condition.

The control of target protein levels afforded by the present disclosure provides treatment of a disease state or condition by lowering the level of the target protein in the cell, e.g., cell of a patient. In certain embodiments, the method comprises administering an effective amount of a compound as described herein, optionally including a pharmaceutically acceptable excipient.

In additional embodiments, the description provides methods for treating or ameliorating a disease, disorder or symptom thereof in a subject or a patient, e.g., an animal such as a human, comprising administering to the subject or patient in need thereof a pharmaceutical composition comprising an effective amount, e.g., a therapeutically effective amount, of a bifunctional compound of Formula (I) as described herein, or a pharmaceutically acceptable salt, solvate, or isotopic derivative thereof, and a pharmaceutically acceptable excipient, carrier, adjuvant, another bioactive agent or combination thereof, wherein the composition is effective for treating or ameliorating the disease or disorder or symptom thereof in the subject or patient.

In another embodiment, the present disclosure is directed to a method of treating a human subject or patient in need thereof for a disease state or condition modulated through the target protein where the degradation of that protein will produce a therapeutic effect in that patient, the method comprising administering to the subject or patient in need thereof an effective amount of a compound according to the present disclosure, optionally in combination with another bioactive agent.

A compound of formula INT-IV, wherein R³ is an ether, alkyl group or an amine and R⁴ is optionally H, an amine, methyl, or chloro group, may be reacted with a reagent INT-II (commercially available or readily prepared using standard reaction techniques known to one skilled in the art) under reductive amination or alkylation conditions to produce a compound of formula INT-VI, wherein L and n are as defined herein. Compounds of formula INT-VI can be furnished from N-alkylation where G is an appropriate leaving group (e.g., OMs, OTs, Cl, etc.) or through reductive amination where G is an aldehyde or ketone. When G is a leaving group, suitable reaction conditions are those for an alkylation reaction, e.g., diisopropylethylamine, potassium iodide, DMSO or acetonitrile, 80° C. When G is a carbonyl, suitable reaction conditions are those for a reductive amination reaction, e.g., sodium cyanoborohydride, methanol, dichloromethane, acetic acid, room temperature. Compounds of formula INT-VI can then be reacted with compounds of formula INT-I wherein Q is CH₂ or C═O and X^S1 is an alcohol or a halide to produce compound of formula CMPD-V.

Preparation of Example 57: N-(2-(1-((1-(2-(2,6-dioxopiperidin-3-yl)-1,3-dioxoisoindolin-5-yl)-3-fluoroazetidin-3-yl)methyl)piperidin-4-yl)-6-isopropoxy-1-oxoisoindolin-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide

Step 1:

To a mixture of tert-butyl 3-fluoro-3-(hydroxymethyl)azetidine-1-carboxylate (5.0 g, 24.4 mmol, 1 eq), triethylamine (7.40 g, 73.09 mmol, 10.17 mL, 3 eq) in dichloromethane (150 mL) was added 4-methylbenzene-1-sulfonyl chloride (7.50 g, 39.34 mmol, 1.61 eq) at 0° C. The reaction mixture was allowed to stir at 20° C. for 10 h under an atmosphere of nitrogen. The mixture was washed with brine (50 mL×3), dried over anhydrous sodium sulfate, concentrated in vacuum to give a residue. The residue was purified by silica gel column chromatography (eluted with petroleum ether/ethyl acetate=10/1 to 3/1) to afford tert-butyl 3-fluoro-3-((tosyloxy)methyl)azetidine-1-carboxylate (8.0 g, 22.3 mmol, 91% yield) as a white solid. ¹H NMR (400 MHz, CDCl₃) δ=7.81 (d, J=8.0 Hz, 2H), 7.38 (d, J=8.4 Hz, 2H), 4.31-4.21 (m, 2H), 4.10-3.89 (m, 4H), 2.47 (s, 3H), 1.44 (s, 9H).

Step 2:

To a solution of N-(6-isopropoxy-1-oxo-2-(piperidin-4-yl)isoindolin-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (100 mg, 230.2 mmol, 1 eq) in dimethyl sulfoxide (2 mL) was added N,N-diisopropylethylamine (148.7 mg, 1.15 mmol, 200.4 mL, 5 eq) and tert-butyl 3-fluoro-3-((tosyloxy)methyl)azetidine-1-carboxylate (165.4 mg, 460.3 mmol, 2 eq). The mixture was stirred at 100° C. for 12 h. To the reaction mixture was added water (10 mL) and the mixture was extracted with ethyl acetate (20 mL×3). The combined organic phase was washed with brine (20 mL), dried over anhydrous sodium sulfate, filtered, and concentrated in vacuum. Crude tert-butyl 3-fluoro-3-((4-(6-isopropoxy-1-oxo-5-(pyrazolo[1,5-a]pyrimidine-3-carboxamido)isoindolin-2-yl)piperidin-1-yl)methyl)azetidine-1-carboxylate (140 mg) was obtained as a white solid and used in subsequent reactions without further purification. LCMS (ESI) m/z: 622.3 [M+H]⁺.

Step 3:

To a solution of tert-butyl 3-fluoro-3-((4-(6-isopropoxy-1-oxo-5-(pyrazolo[1,5-a]pyrimidine-3-carboxamido)isoindolin-2-yl)piperidin-1-yl)methyl)azetidine-1-carboxylate (65 mg, 104.5 mmol, 1 eq) in dichloromethane (3 mL) was added trifluoroacetic acid (4.62 g, 40.5 mmol, 3 mL, 387.54 eq). The mixture was stirred at 25° C. for 1 h. The reaction mixture was concentrated under reduced pressure. The residue was diluted with a saturated solution of sodium carbonate (50 mL) and extracted with ethyl acetate (50 mL×4). The combined organic layers were washed with brine (50 mL×2), dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to afford N-(2-(1-((3-fluoroazetidin-3-yl)methyl)piperidin-4-myl)-6-isopropoxy-1-oxoisoindolin-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (50 mg, 95.9 mmol, 92% yield) as a white solid which was used in the next step without further purification. MS (ESI) m/z: 522.1 [M+H]⁺.

Step 4:

To a solution of N-(2-(1-((3-fluoroazetidin-3-yl)methyl)piperidin-4-yl)-6-isopropoxy-1-oxoisoindolin-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (60 mg, 115 mmol, 1 eq) in dimethyl sulfoxide (1 mL) was added N,N-diisopropylethylamine (44.6 mg, 345.1 mmol, 60.1 mL, 3 eq) and 2-(2,6-dioxo-3-piperidyl)-5-fluoro-isoindoline-1,3-dione (60.0 mg, 217.2 mmol, 1.89 eq). The mixture was stirred at 100° C. for 10 h. The reaction mixture was allowed to cool to room temperature and quenched by the addition of water (20 mL) at 0° C. The mixture was then diluted with water 10 mL and extracted with ethyl acetate (50 mL×2). The combined organic layers were washed with brine (15 mL×2), dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to give a residue. The residue was purified by preparative HPLC (column: Unisil 3-100 C18 Ultra 150×50 mm×3 mm; mobile phase: [water(0.225% formic acid)-acetonitrile]; B %: 18%-48%, 10 min) to afford N-(2-(1-((1-(2-(2,6-dioxopiperidin-3-yl)-1,3-dioxoisoindolin-5-yl)-3-fluoroazetidin-3-yl)methyl)piperidin-4-yl)-6-isopropoxy-1-oxoisoindolin-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (8.1 mg, 9.79 mmol, 90 yield, 94) purity) as a white solid.

Example 117

A compound of formula INT-I, where in X^S1 is a halide or alcohol, may be reacted with a reagent INT-II (commercially available or readily prepared using standard reaction techniques known to one skilled in the art) under etherification or alkylation conditions to produce a compound of formula INT-III, wherein L and n are as defined herein, and Q is CH₂ or C═O. Compounds of formula INT-III may react with a compound of formula INT-VII, wherein R³ is an ether or alkyl group and R⁴ is optionally substituted as an H, amine, methyl, or chloro group, through N-alkylation where G is an appropriate leaving group (e.g., OMs, OTs, Cl, etc.) or through reductive amination where G is an aldehyde or ketone to produce compound of formula CNPD-VIII. When G is a leaving group, suitable reaction conditions are those for an alkylation reaction, e.g., diisopropylethylamine, potassium iodide, DMSO or acetonitrile, 80° C. When Gis a carbonyl, suitable reaction conditions are those for a reductive amination reaction, e.g., sodium cyanoborohydride, methanol, dichloromethane, acetic acid, room temperature.

Step 1:

To a solution of 2-fluoro-4-hydroxybenzaldehyde (10.0 g, 71.4 mmol, 1 eq) in sulfuric acid (60 mL) cooled to −15° C. was slowly added a mixture of nitric acid (6 mL) and sulfuric acid (14 mL). The mixture was stirred at −15° C. for 1 h then it was poured into water (500 mL) at 0° C. and extracted with ethyl acetate (200 mL×3). The combined organic layers were washed with brine (200 mL×3), dried over anhydrous sodium sulfate, concentrated in vacuo to give a residue. The crude product 2-fluoro-4-hydroxy-5-nitrobenzaldehyde (13.2 g, 71.3 mmol, >98% yield) was obtained as a yellow solid and used in subsequent transformations without further purification.

Step 2:

To a solution of 2-fluoro-4-hydroxy-5-nitrobenzaldehyde (15.0 g, 81.03 mmol, 1 eq) in N,N-dimethylformamide (100 mL) was added potassium carbonate (34 g, 246.0 mmol, 3.04 eq) and (bromomethyl)cyclopropane (15 g, 111.1 mmol, 10.64 mL, 1.37 eq). The mixture was stirred at 60° C. for 12 h. The reaction mixture was poured into water (300 mL) at 0° C., and then extracted with ethyl acetate (200 mL×3). The combined organic layers were washed with brine (200 mL×3), dried over anhydrous sodium sulfate, concentrated under reduced pressure to give a residue. The residue was purified by column chromatography (silicon dioxide, eluted with petroleum ether/ethyl acetate=20:1 to 3:1) to afford 4-(cyclopropylmethoxy)-2-fluoro-5-nitrobenzaldehyde (6.5 g, 27.17 mmol, 34% yield) as a yellow solid. MS (ESI) m/z: 240.1 [M+H]⁺.

A compound of formula INT-VII, wherein R³ is an ether or alkyl group and R⁴ optionally substitutes as an H, an amine, methyl, or chloro group, may be reacted with a reagent INT-II (commercially available or readily prepared using standard reaction techniques known to one skilled in the art) under reductive amination or alkylation conditions to produce a compound of formula INT-IX, wherein L and n are as defined herein. Compounds of formula INT-IX can be furnished from N-alkylation where G is an appropriate leaving group (e.g., OMs, OTs, Cl, etc.) or through reductive amination where G is an aldehyde. When G is a leaving group, suitable reaction conditions are those for an alkylation reaction, e.g., diisopropylethylamine, potassium iodide, DMSO or acetonitrile, 80° C. When G is an aldehyde, suitable reaction conditions are those for a reductive amination reaction, e.g., sodium cyanoborohydride, methanol, dichloromethane, acetic acid, room temperature. Compounds of formula INT-IX can then be reacted with compounds of formula INT-I wherein Q is CH₂ or C═O and X^S1 is an alcohol or a halide to produce compound of formula CVIPD-VIII.

Preparation of Example 161: N-(6-(cyclopropylmethoxy)-2-(1-((1-(2-(2,6-dioxopiperidin-3-yl)-1,3-dioxoisoindolin-5-yl)-3-fluoroazetidin-3-yl)methyl)piperidin-4-yl)-2H-indazol-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide

Step 1:

To a mixture of N-(6-(cyclopropylmethoxy)-2-(piperidin-4-yl)-2H-indazol-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (1.3 g, 3.01 mmol, 1 eq) and diisopropylethylamine (1.95 g, 15.09 mmol, 2.63 mL, 5.01 eq) in dimethyl sulfoxide (10 mL) was added tert-butyl 3-fluoro-3-((tosyloxy)methyl)azetidine-1-carboxylate (2.60 g, 7.23 mmol, 2.40 eq) at 0° C. The reaction mixture was then heated to 100° C. for 10 h under an atmosphere of nitrogen. To the mixture was added tert-butyl 3-fluoro-3-((tosyloxy)methyl)azetidine-1-carboxylate (1.30 g, 3.62 mmol, 1.2 eq) and then the mixture was stirred at 100° C. for 24 h under an atmosphere of nitrogen. The reaction was quenched with ice water (100 mL) and extracted with ethyl acetate (150 mL×3). The combined organic phases were washed with brine (200 mL), dried over anhydrous sodium sulfate, concentrated in vacuo to give a residue. The residue was purified by silica gel column chromatography (eluted with petroleum ether:ethyl acetate=1:1 to 0:1) to afford tert-butyl 3-((4-(6-(cyclopropylmethoxy)-5-(pyrazolo[1,5-a]pyrimidine-3-carboxamido)-2H-indazol-2-yl)piperidin-1-yl)methyl)-3-fluoroazetidine-1-carboxylate (1.0 g, 1.62 mmol, 54% yield, >98% purity) as a yellow solid. MS (ESI) m/z: 619.3 [M+H]⁺. ¹H NMR (400 MHz, CDCl₃) δ=10.56 (s, 1H), 8.89 (s, 1H), 8.85-8.76 (m, 2H), 8.68 (dd, J=1.6, 4.0 Hz, 1H), 7.86 (s, 1H), 7.03 (dd, J=4.4, 7.2 Hz, 1H), 7.00 (s, 1H), 4.39-4.26 (m, 1H), 4.09-3.95 (m, 6H), 3.10 (br d, J=11.6 Hz, 2H), 2.88-2.78 (m, 2H), 2.49-2.37 (m, 2H), 2.27-2.18 (m, 4H), 1.55-1.43 (m, 10H), 0.75-0.69 (m, 2H), 0.56-0.50 (q, J=4.8 Hz, 2H).

The reaction mixture was allowed to stir at 25° C. for 1 h under an atmosphere of nitrogen. The reaction mixture was concentrated under reduced pressure to give a residue which was redissolved in a 10:1 mixture of dichloromethane to methanol (200 mL) and ammonia hydrate (2 mL). The organic layer was separated, dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure to give a residue. The crude product N-(6-(cyclopropylmethoxy)-2-(1-((3-fluoroazetidin-3-yl)methyl)piperidin-4-yl)-2H-indazol-5-yl)pyrazolo[1,5-a]pyrimidine-3-carboxamide (0.8 g, 1.54 mmol, 95% yield) was obtained as a yellow solid which was used in subsequent transformations without further purification. MS (ESI) m/z: 519.3 [M+H]⁺.

Step 3:

A compound of formula INT-XIX, wherein R³ is an ether, an amine, or an alkyl group and W¹ is optionally N or C═O, can be prepared through substitution of 4-amino-1-Boc-piperidine in step 5 or step 4 of Scheme 1C or Scheme 3A, respectively, with either trans or cis N-Boc-1,4-cyclohexanediamine. A compound of formula INT-XIX may be reacted with a reagent INT-II (commercially available or readily prepared using standard reaction techniques known to one skilled in the art) under reductive amination or alkylation conditions to produce a compound of formula INT-XX, wherein L and n are as defined herein. Compounds of formula INT-XX can be furnished from N-alkylation where G is an appropriate leaving group (e.g., OMs, OTs, Cl, etc.) or through reductive amination where G is an aldehyde or ketone. When G is a leaving group, suitable reaction conditions are those for an alkylation reaction, e.g., diisopropylethylamine, potassium iodide, DMSO or acetonitrile, 80° C. When G is an aldehyde, suitable reaction conditions are those for a reductive amination reaction, e.g., sodium cyanoborohydride, methanol, dichloromethane, acetic acid, room temperature. Treatment of compounds of formula INT-XX with a suitable reagent for alkylation (either by S_N2 or reductive amination) of the secondary amine allow for the preparation of synthetic intermediates of the general formula CMPD-XXI. These intermediates can be reacted further as detailed in Schemes 1-6.

PD Study for with in C.B.17 SCID and WT Mice

Cell culture: OCI-Ly1 tumor cells were maintained as a suspension in IMDM medium supplemented with 20% fetal bovine serum under an atmosphere of 5% C02 in air at 37° C. Cell density was maintained below 1×106/mL.

Animals: Female C.B. 17 SCID mice aged 6-8 weeks weighing between 16-18 g were used and maintained according to IACUC protocols.

Tumor Inoculation: Each mouse was inoculated with OCI-Ly1 tumor cells (10×106) in 0.1 mL of RPMI with Matrigel. Treatment was initiated when the tumor sizes reached 400 m3.

A PD Study in C.B.17 SCID Mice with OCI-LY1 Tumor Xenograft was Performed

In FIG. 2, animals were dosed orally after tumors were inoculated and the tumor sizes reached 400 m3, with 5, 15, or 50 mg/kg formulated with 10% DMSO, 90% (2% Tween 80 in PEG 400) and sacrificed humanely 24 hours post-dose. Blood was obtained for isolation of plasma for terminal compound exposure. Tumors was removed and divided in 2 portions, one each for terminal compound concentration and for determination of IRAK-4 content. Compound concentrations were determined by LC/MS with calibrated standards. IRAK-4 content in tumor lysate was quantified by ELISA and normalized to total protein concentration per sample. Tumor samples were lysed by homogenization in T-PER and Halt Protease and Phosphatase inhibitors. It was found that IRAK-4 concentration in the tumor samples were lower in the cells treated with the high concentrations of Example 112.

A PD Study in Wild Type Mice was Performed

In FIGS. 3A and 3B, mice were randomly assigned to each treatment group. Animals were dosed orally with 10, 30, or 90 mg/kg compound formulated in 10% DMSO, 90% (2% Tween 80 in PEG 400) and terminated 24 h later. At termination, plasma, spleen and lung tissue were collected for analysis of compound concentration and IRAK-4 quantification. Spleen and lung were snap frozen. IRAK-4 content in any tissue is assessed with the same protocol described for tumor lysates. It was found that IRAK-4 concentration in the cell samples were much lower in the cells treated with Example 167 (FIG. 3A) and Example 112 (FIG. 3B).
