Definitions
- the present disclosure generally relates to inhibitors of interleukin-1 receptor associated kinase (IRAK) /FMS-like receptor tyrosine kinase (FLT3) , pharmaceutical products thereof, productions thereof, and applications thereof.
- IRAK interleukin-1 receptor associated kinase
- FLT3 FMS-like receptor tyrosine kinase
- the present disclosure can also include applications of the compounds and derivatives thereof in prophylaxis and/or treatment of a broad range of disorders or diseases related to or mediated by IRAK /FLT3, or associated with aberrant IRAK /FLT3 activity, for example, inflammatory diseases, infections such as viral, bacterial, fungal, and parasitic infections, HIV-1 infection, sepsis, autoimmune disorders or diseases such as rheumatoid arthritis and multiple sclerosis, gout, juvenile idiopathic arthritis, Muckle-Wells disease, familial
- inflammatory diseases infections such as viral, bacterial, fungal, and
- kinases are very important targets for the development of medicines for the prophylaxis and/or treatment of various diseases and disorders, simply because kinases are involved in many essential processes of cell physiology, for example protein phosphorylation.
- protein and lipid kinases are involved in the activation, growth, differentiation, and survival of cells. Protein kinases can be divided between those preferentially phosphorylating tyrosine residues, and those preferentially phosphorylating serine and/or threonine residues.
- IRAK kinases and more particularly IRAK-4, have been identified as playing a role in inflammation and autoimmune diseases.
- IRAKs are expressed in many cell types and mediate signals from various cell receptors including interleukin-1 (IL-1) and toll-like receptors (TLRs) .
- IL-1R and Toll-like receptors sharing the conserved Toll/IL-1R domain, function as a crucial part in innate immunology.
- Toll/IL-1 receptors Upon binding with LPS or cytokines, Toll/IL-1 receptors recruit adaptor molecule MyD88 through TIR domain, initiating downstream protein complex assembling and phosphorylation cascade, resulting in induction of inflammation cytokines and chemokines such as TNF- ⁇ , IL-1 ⁇ , IL-6 and IL-8.
- the IL-1R-associated kinase (IRAK) family plays an important role, both in scaffold and kinase function.
- the IL-1R associated kinase (IRAK) family consists of four members, IRAK1, IRAK2, IRAKM, and IRAK4.
- IRAK1 and IRAK4 are active kinases and the other two are not. However, they all regulate the nuclear factor- ⁇ B (NF- ⁇ B) and mitogen-activated protein kinase (MAPK) pathways.
- NF- ⁇ B nuclear factor- ⁇ B
- MAPK mitogen-activated protein kinase
- IRAK4 represents an attractive therapeutic target.
- IRAK4 is a threonine/serine protein kinase made up of 460 amino acids, containing a kinase domain and a death domain.
- the N-terminal lobe and the C-terminal lobe can be found in the kinase domain, which meet together to form the ATP binding site.
- the death domain exists to bind and interact with MyD88 during protein recruitment.
- IRAK4 is believed to be the key protein kinase activated early downstream of the IL-1 receptor and TLRs, initiating signaling via rapid activation of IRAK1 and IRAK2, leading to innate immune responses. Also, other interleukins, such as IL-18 and IL-33, are dependent on IRAK4 for signaling. As such, diseases for which these cytokines are involved in the pathogenic process (e.g., fibrosis) and atopic dermatitis are potential target diseases for treatment by IRAK4 inhibitors.
- mice expressing an inactive IRAK4 mutant instead of wild type complete resistance to septic shock triggered by several TLR agonists as well as impaired response to IL-1 is observed. Furthermore, mice expressing an inactive IRAK4 mutant instead of wild type are partially protected in several models of auto-immune diseases, such as rheumatoid arthritis and multiple sclerosis. Interestingly, the serum of rheumatoid arthritis and systemic lupus erythematosus patients has been shown to activate plasmacytoid dendritic cells in an IRAK4 dependent manner. Finally, recurring pyogenic bacterial infection has been observed in children suffering from genetic defects leading to IRAK4 inactivity.
- IRAK4 is regarded as the “Master IRAK” , since it acts as the central component in the signaling pathway.
- IRAK4 binds to MyD88 with the death domain, recruiting IRAK1 and IRAK2, to form the MyD88–IRAK4–IRAK2 complex or so called ‘myddosome’ .
- Crystal structure reveals that it consists of 6 MyD88, 4 IRAK4 and 4 IRAK2 death domains, exhibiting as a left-handed helical oligomer.
- IRAK4 phosphorylates IRAK1 or IRAK2 in the myddosome, resulting in the recruitment of TNF receptor associated factor 6 (TRAF6) , triggering the initiation of signal transduction events for NF- ⁇ B-mediated transcription activation.
- TNF receptor associated factor 6 TNF receptor associated factor 6
- IRAK4 is important for innate immunity.
- their whole blood cells or PBMCs do not respond to IL-1 ⁇ , in terms of IL-6 secretion, or to IL-18, in terms of IFN- ⁇ production.
- stimulating TLR1/2, TLR2/6, TLR3, TLR4, TLR5, and TLR9 do not induce the production of major inflammatory cytokines (TNF- ⁇ , IL-6, and IL-12) and growth factors (G-CSF and GM-CSF) in whole blood cells and PBMCs.
- TNF- ⁇ , IL-6, and IL-12 major inflammatory cytokines
- G-CSF and GM-CSF growth factors
- adult patients with the deficiency are not prone to chronic infections indicating that there might be some certain mechanisms for bypassing the deficiency in TLR signaling.
- IRAK4 is also associated with cancer due to the downstream pathway it regulates.
- the discovery of oncogenically active MyD88 mutations in activated B-cell-like diffuse large B-cell lymphoma (ABC DLBCL) reveals the cancer-specific dependencies on IRAK signaling.
- Sequence analysis of the MyD88 coding region in a large amount of tumor biopsies indicated that 29%of ABC DLBCL tumors harbor the L265P single amino acid substitution within the MyD88 TIR domain, which is absent in other DLBCL subtypes.
- the L265P MyD88 mutant promotes cell survival through spontaneous assembly of a protein-signaling complex containing IRAK1 and IRAK4, leading to IRAK4 kinase activation, IRAK1 phosphorylation, and activated JAK-STAT and NF- ⁇ B signaling. Moreover, the common somatic L265P mutation of MyD88 occurs in 91%of patients with Macroglobulinaemia, a kind of lymphocytic hematological malignancy.
- MYD88 an adaptor molecule downstream of the TLR and IL-1R, which activates IRAK4.
- Activating MYD88 mutations have been identified in e.g., diffuse large B-cell lymphomas (DLBCL) , and in Waldenstrom macroglobulinemia.
- DLBCL diffuse large B-cell lymphomas
- T-ALL T-cell acute lymphoblastic leukemia
- the pharmacological inhibition of IRAK-4 has been shown to enhance the sensitivity of T-ALL to chemotherapeutic agents.
- IL-33 has been shown to play a role in the development of fibrotic and allergic diseases, asthma and atopic dermatitis in particular. As this cytokine signals through an IRAK4 dependent pathway, these diseases might also represent a target for IRAK4 inhibitors. Furthermore, several auto-inflammatory diseases have been shown to be dependent on IL-1 activity and, as a consequence, IL-1 blocking biologicals show some benefit to these patients. Gout, juvenile idiopathic arthritis, Muckle-Wells disease, familial Mediterranean fever, Behcet's disease, adult onset Still's disease are examples of such auto-inflammatory diseases.

Description
The present disclosure generally relates to inhibitors of interleukin-1 receptor associated kinase (IRAK) /FMS-like receptor tyrosine kinase (FLT3) , pharmaceutical products thereof, productions thereof, and applications thereof. Although the disclosure will be illustrated, explained and exemplified by the application of a class of compounds in the prophylaxis and/or treatment of inflammatory diseases, autoimmune diseases, and/or proliferative diseases, it should be appreciated that the present disclosure can also include applications of the compounds and derivatives thereof in prophylaxis and/or treatment of a broad range of disorders or diseases related to or mediated by IRAK /FLT3, or associated with aberrant IRAK /FLT3 activity, for example, inflammatory diseases, infections such as viral, bacterial, fungal, and parasitic infections, HIV-1 infection, sepsis, autoimmune disorders or diseases such as rheumatoid arthritis and multiple sclerosis, gout, juvenile idiopathic arthritis, Muckle-Wells disease, familial Mediterranean fever, Behcet’s disease, adult onset Still’s disease, proliferative diseases such as cancer, hyperplasia, restenosis, cardiac hypertrophy, leukemia, intravascular coagulation, bone diseases, metabolic diseases, neurological and neurodegenerative diseases, cardiovascular diseases, fibrotic and allergic diseases, asthma, atopic dermatitis, Alzheimer's disease, hormone-related diseases, trauma (surgery) , hemodialysis, ischemic diseases (myocardial infarction) , noninfectious hepatitis, UV radiation, closed head injury, pancreatitis, periodontitis, graft-versus-host disease, transplant rejection, and the like. The interleukin-1 receptor associated kinase (IRAK) mentioned above can be IRAK4.
Kinases are very important targets for the development of medicines for the prophylaxis and/or treatment of various diseases and disorders, simply because kinases are involved in many essential processes of cell physiology, for example protein phosphorylation. In particular, protein and lipid kinases are involved in the activation, growth, differentiation, and survival of cells. Protein kinases can be divided between those preferentially phosphorylating tyrosine residues, and those preferentially phosphorylating serine and/or threonine residues.
In particular, IRAK kinases, and more particularly IRAK-4, have been identified as playing a role in inflammation and autoimmune diseases. IRAKs are expressed in many cell types and mediate signals from various cell receptors including interleukin-1 (IL-1) and toll-like receptors (TLRs) . IL-1R and Toll-like receptors, sharing the conserved Toll/IL-1R domain, function as a crucial part in innate immunology. Upon binding with LPS or cytokines, Toll/IL-1 receptors recruit adaptor molecule MyD88 through TIR domain, initiating downstream protein complex assembling and phosphorylation cascade, resulting in induction of inflammation cytokines and chemokines such as TNF-α, IL-1β, IL-6 and IL-8. Through the MyD88-dependent pathway, the IL-1R-associated kinase (IRAK) family plays an important role, both in scaffold and kinase function. The IL-1R associated kinase (IRAK) family consists of four members, IRAK1, IRAK2, IRAKM, and IRAK4. IRAK1 and IRAK4 are active kinases and the other two are not. However, they all regulate the nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) pathways.
In the IRAK family, IRAK4 represents an attractive therapeutic target. IRAK4 is a threonine/serine protein kinase made up of 460 amino acids, containing a kinase domain and a death domain. Typically, the N-terminal lobe and the C-terminal lobe can be found in the kinase domain, which meet together to form the ATP binding site. The death domain exists to bind and interact with MyD88 during protein recruitment. Besides, there are three phosphorylation sites on the protein, which are involved in trans-phosphorylation. IRAK4 is believed to be the key protein kinase activated early downstream of the IL-1 receptor and TLRs, initiating signaling via rapid activation of IRAK1 and IRAK2, leading to innate immune responses. Also, other interleukins, such as IL-18 and IL-33, are dependent on IRAK4 for signaling. As such, diseases for which these cytokines are involved in the pathogenic process (e.g., fibrosis) and atopic dermatitis are potential target diseases for treatment by IRAK4 inhibitors.
In mice expressing an inactive IRAK4 mutant instead of wild type, complete resistance to septic shock triggered by several TLR agonists as well as impaired response to IL-1 is observed. Furthermore, mice expressing an inactive IRAK4 mutant instead of wild type are partially protected in several models of auto-immune diseases, such as rheumatoid arthritis and multiple sclerosis. Interestingly, the serum of rheumatoid arthritis and systemic lupus erythematosus patients has been shown to activate plasmacytoid dendritic cells in an IRAK4 dependent manner. Finally, recurring pyogenic bacterial infection has been observed in children suffering from genetic defects leading to IRAK4 inactivity.
Moreover, IRAK4 is regarded as the “Master IRAK” , since it acts as the central component in the signaling pathway. As a scaffold protein, IRAK4 binds to MyD88 with the death domain, recruiting IRAK1 and IRAK2, to form the MyD88–IRAK4–IRAK2 complex or so called ‘myddosome’ . Crystal structure reveals that it consists of 6 MyD88, 4 IRAK4 and 4 IRAK2 death domains, exhibiting as a left-handed helical oligomer. As a kinase, IRAK4 phosphorylates IRAK1 or IRAK2 in the myddosome, resulting in the recruitment of TNF receptor associated factor 6 (TRAF6) , triggering the initiation of signal transduction events for NF-κB-mediated transcription activation.
As a result, IRAK4 is important for innate immunity. For IRAK4-deficient children, their whole blood cells or PBMCs do not respond to IL-1β, in terms of IL-6 secretion, or to IL-18, in terms of IFN-γ production. Additionally, stimulating TLR1/2, TLR2/6, TLR3, TLR4, TLR5, and TLR9, do not induce the production of major inflammatory cytokines (TNF-α, IL-6, and IL-12) and growth factors (G-CSF and GM-CSF) in whole blood cells and PBMCs. However, adult patients with the deficiency are not prone to chronic infections indicating that there might be some certain mechanisms for bypassing the deficiency in TLR signaling. Recent investigation discovers that, myddosome formation remains stable without IRAK4’s kinase activity, suggesting that this function is dispensable for myddosome assembly and activation of the NF-κB and MAPK pathways but is essential for MyD88-dependent production of inflammatory cytokines. Thus, inhibiting IRAK4 can be a potential therapeutic strategy for autoimmune diseases, which are with overactive TLR signaling, while the anti-infection function of immunity can be still maintained.
IRAK4 is also associated with cancer due to the downstream pathway it regulates. The discovery of oncogenically active MyD88 mutations in activated B-cell-like diffuse large B-cell lymphoma (ABC DLBCL) reveals the cancer-specific dependencies on IRAK signaling. Sequence analysis of the MyD88 coding region in a large amount of tumor biopsies indicated that 29%of ABC DLBCL tumors harbor the L265P single amino acid substitution within the MyD88 TIR domain, which is absent in other DLBCL subtypes. The L265P MyD88 mutant promotes cell survival through spontaneous assembly of a protein-signaling complex containing IRAK1 and IRAK4, leading to IRAK4 kinase activation, IRAK1 phosphorylation, and activated JAK-STAT and NF-κB signaling. Moreover, the common somatic L265P mutation of MyD88 occurs in 91%of patients with
Macroglobulinaemia, a kind of lymphocytic hematological malignancy.
Several cancer types have been shown to be dependent on activated forms of MYD88, an adaptor molecule downstream of the TLR and IL-1R, which activates IRAK4. Activating MYD88 mutations have been identified in e.g., diffuse large B-cell lymphomas (DLBCL) , and in Waldenstrom macroglobulinemia. There is a report supporting the role of IRAK4 in the field of oncology, T-cell acute lymphoblastic leukemia (T-ALL) in particular. The pharmacological inhibition of IRAK-4 has been shown to enhance the sensitivity of T-ALL to chemotherapeutic agents. IL-33 has been shown to play a role in the development of fibrotic and allergic diseases, asthma and atopic dermatitis in particular. As this cytokine signals through an IRAK4 dependent pathway, these diseases might also represent a target for IRAK4 inhibitors. Furthermore, several auto-inflammatory diseases have been shown to be dependent on IL-1 activity and, as a consequence, IL-1 blocking biologicals show some benefit to these patients. Gout, juvenile idiopathic arthritis, Muckle-Wells disease, familial Mediterranean fever, Behcet's disease, adult onset Still's disease are examples of such auto-inflammatory diseases.
All the evidence supports that suppression of IRAK4-mediated signaling would be a promising therapeutic approach. Consequently, the development of selective IRAK4 inhibitors has been a focus for many pharmaceutical researchers. So far, many companies have taken part in the competition in this field. Pfizer has finished a Phase Ⅱ study on Rheumatoid Arthritis (NCT 02996500) for the clinical compound PF-06650833, which gave an excellent performance during preclinical investigation. Aurigene/Curis also discovered a small molecular IRAK4 inhibitor, targeting on hematologic malignancy. Its CA-4948 is undergoing Phase Ⅰ study (NCT03328078) . Additionally, Bayer has developed a series of compounds with the similar core as that of Curis’s, used for inflammation therapy, and several Phase Ⅰ studies have completed.
However, the state of the prior art is not satisfactory, and there remains a need to identify small molecules with novel structure that may be of use in the prophylaxis and/or treatment of IRAK4-related disorders and diseases, e.g. inflammatory diseases, autoimmune diseases and/or proliferative diseases, among others.
In addition, the prior arts had evienced that activation of innate immune stress response pathways after treatment of FLT3-mutant AML cells with FLT3i and showed that innate immune pathway activation via the interleukin-1 receptor–associated kinase 1 and 4 (IRAK1/4) complex contributes to adaptive resistance in FLT3-mutant AML cells. Small molecule that simultaneously inhibits FLT3 and IRAK1/4 kinases may be effective to overcome this adaptive resistance mechanism.

The term “non-hydrogen monovalent group” may include a combination of any number of groups selected from the above 8 classes. By a combination of two groups, it means that one group (G1) is substituted with another group (G2) to form a new group -G1-G2. By combination of three groups, it means that a first group (G1) is substituted with a second group (G2) which is substituted with a third group (G3) , forming a new group -G1-G2-G3. For example, a group from Classes (2) - (8) may be substituted with a group from Class (1) : (i) Haloalkyl group such as fluoroalkyl, i.e. an alkyl group having one or more halogen substituents such as F (up to perhaloalkyl, i.e., every hydrogen atom of the alkyl group has been replaced by a halogen atom) . For example, C1-6 haloalkyl is a C1-6 alkyl group having one or more halogen substituents (up to perhaloalkyl, i.e., every hydrogen atom of the alkyl group has been replaced by a halogen atom) . C1 haloalkyl is a methyl group having one, two, or three halogen substituents. (ii) Hydroxylalkyl or hydroxyalkyl, i.e. an alkyl group having one or more (e.g., 1, 2, or 3) OH substituents. (iii) Cyanoalkyl group, i.e an alkyl group having one or more (e.g., 1, 2, or 3) -CN substituents. A group from Class (1) may be substituted with another group from Class (1) , e.g. haloalkoxy group such as fluoroalkoxy, i.e. an-O-haloalkyl group. C1-6 haloalkoxy refers to an -O- (C1-6 haloalkyl) group.
The term “non-hydrogen monovalent group” may also be any group selected from the above 8 classes and combination of any number of groups selected from the above 8 classes, that are substituted with one or more bivalent groups, i.e. two germinal hydrogens on a same atom are replaced with a group such as =O, =S, =NNR
2, =NNRC (=O) R, =NNRC (=O) OR, =NNRS (=O)
2R, =NR, =NOR, or the like.

Generally, the point of attachment of the non-hydrogen monovalent group (U, V and W in Formula (I) ) can be from any suitable position. For example, piperidinyl can be piperidin-1-yl (attached through the N atom of the piperidinyl) , piperidin-2-yl (attached through the C atom at the 2-position of the piperidinyl) , piperidin-3-yl (attached through the C atom at the 3-position of the piperidinyl) , or piperidin-4-yl (attached through the C atom at the 4-position of the piperidinyl) . For another example, pyridinyl (or pyridyl) can be 2-pyridinyl (or pyridin-2-yl) , 3-pyridinyl (or pyridin-3-yl) , or 4-pyridinyl (or pyridin-4-yl) . The point of attachment of the non-hydrogen monovalent group can be specified to indicate the position where the non-hydrogen monovalent group is attached to another moiety. For example, “-C
1-2alkyl- (C
3-4cycloalkyl) ” means the point of attachment occurs at the “C
1-2 alkyl” part. For another example, “ (C
3-4 cycloalkyl) -C
1-2 alkyl-” also means the point of attachment occurs at the “C
1-2 alkyl” part. When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any of the ring-forming atoms in that ring that are substitutable (i.e., one or more hydrogen atoms) , unless otherwise specified or otherwise implicit from the context.

The present disclosure may include all pharmaceutically acceptable isotopically labelled compounds of Formula (I) or salts thereof, 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 disclosure 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 Formula (I) , 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 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 Formula (I) can generally be prepared by conventional techniques known to those skilled in the art using an appropriate isotopically labeled reagent in place of the non-labeled reagent previously employed.
Regarding iosmers, some compounds of Formula (I) may include stereoisomers and tautomers, all of which are included within the scope of the disclosure. Stereoisomers of Formula (I) include cis and trans isomers, optical isomers such as R and S enantiomers, diastereomers, geometric isomers, rotational isomers, atropisomers, and conformational isomers of the compounds of Formula (I) , including compounds exhibiting more than one type of isomerism; and mixtures thereof (such as racemates and diastereomeric pairs) .
The compounds of Formula (I) may exist in the form of pharmaceutically acceptable salts such as acid addition salts and/or base salts thereof. Suitable acid addition salts are formed from acids which form non-toxic salts e.g. hydrochloride/chloride. Suitable base salts are formed from bases which form non-toxic salts such as calcium and sodium salts. Hemisalts of acids and bases may also be formed, for example, hemisulfate and hemicalcium salts.
The compounds of Formula (I) or a pharmaceutically acceptable salt thereof include all forms of the compound of Formula (I) or pharmaceutically salt thereof, including hydrates, solvates, isomers (e.g. rotational stereoisomers) , crystalline and non-crystalline forms, isomorphs, polymorphs, metabolites, and prodrugs thereof. Compounds of Formula (I) may exist in unsolvated and solvated forms. When the solvent or water is tightly bound, the complex will have a well-defined stoichiometry independent of humidity. When, however, the solvent or water is weakly bound, as in channel solvates and hygroscopic compounds, the water/solvent content will be dependent on humidity and drying conditions.
The compounds of Formula (I) may exist in a continuum of solid states ranging from fully amorphous to fully crystalline. The term “amorphous” refers to a state in which the material lacks long-range order at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from apparent solid to a material with liquid properties occurs, which is characterized by a change of state, typically second order ( “glass transition” ) . The term “crystalline” refers to a solid phase in which the material has a regular ordered internal structure at the molecular level and gives a distinctive X-ray diffraction pattern with defined peaks. Such materials when heated sufficiently will also exhibit the properties of a liquid, but the change from solid to liquid is characterized by a phase change, typically first order ( “melting point” ) . The compounds of the disclosure may also exist in a mesomorphic state (mesophase or liquid crystal) when subjected to suitable conditions. The mesomorphic state is intermediate between the true crystalline state and the true liquid state (either melt or solution) .
The disclosure also relates to prodrugs of the compounds of Formula (I) . Some compounds of Formula (I) may have little or no pharmacological activity themselves, but they can, when administered into or onto the body, be converted into compounds of Formula (I) having the desired activity, for example, by hydrolytic cleavage. Such derivatives are referred to as “prodrugs” . Prodrugs in accordance with the disclosure can, for example, be produced by replacing appropriate functionalities present in the compounds of Formula (I) with certain moieties known to those skilled in the art as “pro-moieties” . In some embodiments, certain compounds of Formula (I) may themselves act as prodrugs of other compounds of Formula (I) . Metabolites of compounds of Formula (I) formed in vivo upon administration of the drug are also included within the scope of the disclosure.
Compound Preparation
Starting materials and intermediates useful for making the compounds of the present disclosure can be obtained from chemical vendors or can be made according to methods described in the chemical art.
Compounds of the disclosure, including salts of the compounds, can be prepared using known organic synthesis techniques and can be synthesized according to any of numerous possible synthetic routes. The reactions for preparing compounds of the disclosure can be carried out in suitable solvents, which can be readily selected by one of skill in the art of organic synthesis. Suitable solvents can be substantially non-reactive with the starting materials (reactants) , the intermediates, or products at the temperatures at which the reactions are carried out, e.g., temperatures that can range from the solvent’s freezing temperature to the solvent’s boiling temperature. A given reaction can be carried out in one solvent or a mixture of more than one solvent. Depending on the particular reaction step, suitable solvents for a particular reaction step can be selected by the skilled artisan.
Preparation of compounds of the disclosure may involve the protection and deprotection of various chemical groups. The need for protection and deprotection, and the selection of appropriate protecting groups, can be readily determined by one skilled in the art. For example, a -CN group can be hydrolyzed to afford an amide group; a carboxylic acid can be converted to an amide; a carboxylic acid can be converted to an ester, which in turn can be reduced to an alcohol, which in turn can be further modified. For another example, an OH group can be converted into a better leaving group such as a methanesulfonate, which in turn is suitable for nucleophilic substitution, such as by a cyanide ion. For another example, an -S-can be oxidized to -S (=O) -and/or -S (=O)
2-. For yet another example, an unsaturated bond such as C-C double bond or C-C triple bond can be reduced to a saturated bond by hydrogenation.
Functional (reactive) groups can be protected/deprotected in the course of the synthetic scheme, if appropriate and/or desired. For example, an OH group can be protected by a benzyl, methyl, or acetyl group, which can be deprotected and converted back to the OH group in a later stage of the synthetic process.

2 group can be protected by a benzyloxycarbonyl (Cbz) or BOC group; conversion back to the NH
2 group can be carried out at a later stage of the synthetic process via deprotection.
Reactions can be monitored according to any suitable method known in the art. For example, product formation can be monitored by spectroscopic means, such as nuclear magnetic resonance spectroscopy (e.g.,
1H or
13C) , infrared spectroscopy, spectrophotometry (e.g., UV-visible) , mass spectrometry, or by chromatographic methods such as high-performance liquid chromatography (HPLC) or thin layer chromatography (TLC) .
In some embodiments, the compounds may exist as stereoisomers, such as atropisomers, racemates, enantiomers, or diastereomers. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate using, for example, chiral high-performance liquid chromatography (HPLC) . Alternatively, the racemate (or a racemic precursor) may be reacted with a suitable optically active compound, for example, an alcohol, or, in the case where the compound contains an acidic or basic moiety, an acid or base such as tartaric acid or 1-phenylethylamine. The resulting diastereomeric mixture may be separated by chromatography and/or fractional crystallization, and one or both of the diastereoisomers converted to the corresponding pure enantiomer (s) by means well known to one skilled in the art. Chiral compounds (and chiral precursors thereof) may be obtained in enantiomerically enriched form using chromatography, typically HPLC, on an asymmetric resin with a mobile phase consisting of a hydrocarbon, typically heptane or hexane, containing from 0%to 50%2-propanol, typically from 2%to 20%, and from 0%to 5%of an alkylamine, typically 0.1%diethylamine. Concentration of the eluate affords the enriched mixture. Stereoisomeric conglomerates may be separated by conventional techniques known to those skilled in the art. Suitable stereoselective techniques are well known to those of ordinary skill in the art. For a compound of Formula (I) that contains an alkenyl or alkenylene group, geometric cis/trans (or Z/E) isomers are possible. Cis/trans isomers may be separated by conventional techniques well known to those skilled in the art, for example, chromatography and fractional crystallization.

Example 302: IRAK4 Biochemical Inhibitory Assay
The IL-1R–associated kinase (IRAK4) co-expressed in an insect cell/baculovirus expression system was purchased from Sino Biological Inc. (Beijing, China) . Biotin-labeled peptide substrate (biotinylated-AGAGRDKYKTLRQIR, ERM-peptide) ) was purchased from GenScript (Nanjing, China) . The Anti-Phospho primary antibody Phospho-Ezrin (Thr567) /Radixin (Thr564) /Moesin (Thr558) (48G2) Rabbit mAb (#3726S) was purchased from Cell Signaling Technology (Danvers, MA) . The secondary antibody PAb Anti Rabbit IgG-Eu cryptate (#61PARTAA) , Streptavidin-XL665 (#610SAXLA) that binds to the primary antibody and test buffer Detection buffer (#62SDBRDD) were purchased from Cisbio Bioassays (Codolet, France) . Dithiothreitol (DTT) , magnesium chloride, adenosine triphosphate (ATP) , Tween-20, dimethyl sulfoxide (DMSO) , and HEPES buffer were obtained from Sigma at the highest level of purity available.
General Procedure for IRAK4 Enzyme Inhibitory Assays
Assays were performed in the buffer consisting of 20 mM HEPES, pH 7.5, 5mM MgCl
2 with 0.01%Tween 20 and 1 mM DTT added right before the assay. 2.5 μL of compound solution in the assay buffer with 4%DMSO and 5 μL of IRAK4/ERM-peptide mixture solution in the assay buffer were added into a white low volume 384 well microtiter plate, and phosphorylation was initiated by adding 2.5 μL of ATP solution to the assay buffer. The final concentrations of IRAK4, Biotin-labeled peptide substrate ERM-peptide, ATP and DMSO were 1 nM, 200 nM, 600 μM and 1%. The reaction was allowed to perform for 60 minutes in dark at room temperature after which 2.5 μL primary antibody, 2.5 μL secondary antibody, and 5 μL Streptavidin-XL665 in detection buffer from the manufacturer was added into the reaction mixture followed by incubation for 60 minutes. Final concentration of Streptavidin-XL665 was 50 nM, both primary and secondary antibodies were diluted at the final concentration provided by the manufacturer. Plates were read on a multimode plate reader from Tecan Spark (
Switzerland) and detect the time-resolved fluorescence intensity of the two groups, in which the excitation wavelength was 320 nm, and the emission wavelength was 665 nm and 620nm. By calculating the ratio of 665nm/620nm signals for each individual well, IC
50 values of inhibitors were obtained by fitting the ratio vs inhibitor concentrations in a sigmoidal dose-response curve (variable slopes, four parameters) using Prism 7 (La Jolla, 15CA) . Results for representative compounds described herein are shown in Table 1.
