  • IBD Inflammatory bowel disease
  • Crohn's disease is a group of inflammatory conditions of the colon and small intestine, principally including Crohn's disease and ulcerative colitis, with other forms of IBD representing far fewer cases (e.g., collagenous colitis, lymphocytic colitis, diversion colitis, Behçet's disease and indeterminate colitis).
  • Crohn's disease affects the full thickness of the bowel wall (e.g., transmural lesions) and can affect any part of the gastrointestinal tract, while ulcerative colitis is restricted to the mucosa (epithelial lining) of the colon and rectum.
  • GVHD graft-versus-host disease
  • GVHD is an immune-related disease that can occur following an allogeneic tissue transplant. It is commonly associated with stem cell or bone marrow transplants, but GVHD also applies to other forms of tissue graft. In GVHD immune cells of the tissue graft recognize the recipient host as foreign and attack the host'
  • IBD and GVHD are diseases associated with increased immune activity.
  • the causes of IBD may be related to an aberrant immune response to the microbiota in genetically susceptible individuals.
  • IBD affects over 1.4 million people in the United States and over 2.2 million in Europe and is on the increase. With both environmental and genetic factors playing a role in the development and progression of IBD, response to current treatments (e.g., anti-inflammatory drugs, immune system suppressors, antibiotics, surgery, and other symptom specific medications) are unpredictable.
  • GVHD a fundamental feature of GVHD is increased immune activity.
  • the pathophysiology underlying GVHD is not well understood. It is a significant cause of morbidity and mortality following allogenic haematopoietic stem-cell transplantation and thus the focus of much ongoing research.

  • FIG. 14 Model for the differential cellular responses to EP2/EP4 receptor stimulation versus SIK inhibition. Stimulation of EP2/EP4 prostanoid receptors with PGE 2 increases intracellular cAMP, which promotes IL-10 transcription via CRTC3/CREB complexes downstream of PKA activation. In addition to activating the PKA/CRTC3/CREB axis, cAMP binding to EPAC scaffolding proteins activates Rap1 leading to pleiotropic cellular effects. In contract, inhibition of SIKs up-regulates IL-10 expression by reducing inhibitory phosphorylation of CRTC3 in the absence of a cAMP flux.

Description

    RELATED APPLICATIONS
  • The present application claims priority under 35 U.S.C. §119(e) to U.S. provisional application, U.S. Ser. No. 62/035,332, filed Aug. 8, 2014, which is incorporated herein by reference.
  • BACKGROUND OF THE INVENTION
  • Inflammatory bowel disease (IBD) is a group of inflammatory conditions of the colon and small intestine, principally including Crohn's disease and ulcerative colitis, with other forms of IBD representing far fewer cases (e.g., collagenous colitis, lymphocytic colitis, diversion colitis, Behçet's disease and indeterminate colitis). Pathologically, Crohn's disease affects the full thickness of the bowel wall (e.g., transmural lesions) and can affect any part of the gastrointestinal tract, while ulcerative colitis is restricted to the mucosa (epithelial lining) of the colon and rectum. Graft-versus-host disease (GVHD) is an immune-related disease that can occur following an allogeneic tissue transplant. It is commonly associated with stem cell or bone marrow transplants, but GVHD also applies to other forms of tissue graft. In GVHD immune cells of the tissue graft recognize the recipient host as foreign and attack the host's cells.
  • It has long been recognized that IBD and GVHD are diseases associated with increased immune activity. The causes of IBD, while not well understood, may be related to an aberrant immune response to the microbiota in genetically susceptible individuals. IBD affects over 1.4 million people in the United States and over 2.2 million in Europe and is on the increase. With both environmental and genetic factors playing a role in the development and progression of IBD, response to current treatments (e.g., anti-inflammatory drugs, immune system suppressors, antibiotics, surgery, and other symptom specific medications) are unpredictable.
  • Similarly, a fundamental feature of GVHD is increased immune activity. As yet, the pathophysiology underlying GVHD is not well understood. It is a significant cause of morbidity and mortality following allogenic haematopoietic stem-cell transplantation and thus the focus of much ongoing research. Despite the advances in understanding the pathophysiology (e.g., predisposing factors), a standardized therapeutic strategy is still lacking. Currently both acute and chronic forms of GVHD are treated using corticosteroids (e.g., anti-inflammatory treatments). There is a need for new approaches to treating IBD and GVHD.
  • SUMMARY OF THE INVENTION
  • In one aspect, described herein are novel uses of several compound classes as salt-inducible kinase (SIK) inhibitors.

The described SIK inhibitors are able to inhibit the activity of a SIK (e.g., SIK1, SIK2, SIK3), to enhance interleukin 10 (IL-10) production, and/or to treat and/or prevent inflammatory bowel disease (IBD) and/or graft-versus-host disease (GVHD) in a subject in need thereof.

Wuts, 3rd edition, John Wiley & Sons, 1999, incorporated herein by reference.
  • A “hydrocarbon chain” refers to a substituted or unsubstituted divalent alkyl, alkenyl, or alkynyl group. A hydrocarbon chain includes (1) one or more chains of carbon atoms immediately between the two radicals of the hydrocarbon chain; (2) optionally one or more hydrogen atoms on the chain(s) of carbon atoms; and (3) optionally one or more substituents (“non-chain substituents,” which are not hydrogen) on the chain(s) of carbon atoms. A chain of carbon atoms consists of consecutively connected carbon atoms (“chain atoms”) and does not include hydrogen atoms or heteroatoms. However, a non-chain substituent of a hydrocarbon chain may include any atoms, including hydrogen atoms, carbon atoms, and heteroatoms. For example, hydrocarbon chain —CAH(CBH2CCH3)— includes one chain atom CA, one hydrogen atom on CA, and non-chain substituent —(CBH2CCH3). The term “Cx hydrocarbon chain,” wherein x is a positive integer, refers to a hydrocarbon chain that includes x number of chain atom(s) between the two radicals of the hydrocarbon chain. If there is more than one possible value of x, the smallest possible value of x is used for the definition of the hydrocarbon chain. For example, —CH(C2H5)— is a C1 hydrocarbon chain, and
  • Figure US20170224700A1-20170810-C00035
  • is a C3 hydrocarbon chain. When a range of values is used, the meaning of the range is as described herein. For example, a C3-10 hydrocarbon chain refers to a hydrocarbon chain where the number of chain atoms of the shortest chain of carbon atoms immediately between the two radicals of the hydrocarbon chain is 3, 4, 5, 6, 7, 8, 9, or 10. A hydrocarbon chain may be saturated (e.g., —(CH2)4—). A hydrocarbon chain may also be unsaturated and include one or more C═C and/or C≡C bonds anywhere in the hydrocarbon chain. For instance, —CH═CH—(CH2)2—, —CH2—C≡C—CH2—, and —C≡C—CH═CH— are all examples of a unsubstituted and unsaturated hydrocarbon chain. In certain embodiments, the hydrocarbon chain is unsubstituted (e.g., —C≡C— or —(CH2)4—). In certain embodiments, the hydrocarbon chain is substituted (e.g., —CH(C2H5)— and —CF2—). Any two substituents on the hydrocarbon chain may be joined to form an optionally substituted carbocyclyl, optionally substituted heterocyclyl, optionally substituted aryl, or optionally substituted heteroaryl ring. For instance,
  • Figure US20170224700A1-20170810-C00036
  • are all examples of a hydrocarbon chain. In contrast, in certain embodiments,
  • Figure US20170224700A1-20170810-C00037
  • are not within the scope of the hydrocarbon chains described herein. When a chain atom of a Cx hydrocarbon chain is replaced with a heteroatom, the resulting group is referred to as a Cx hydrocarbon chain wherein a chain atom is replaced with a heteroatom, as opposed to a Cx-1 hydrocarbon chain. For example,
  • Figure US20170224700A1-20170810-C00038
  • is a C3 hydrocarbon chain wherein one chain atom is replaced with an oxygen atom.
  • The term “leaving group” is given its ordinary meaning in the art of synthetic organic chemistry and refers to an atom or a group capable of being displaced by a nucleophile. Examples of suitable leaving groups include, but are not limited to, halogen (such as F, Cl, Br, or I (iodine)), alkoxycarbonyloxy, aryloxycarbonyloxy, alkanesulfonyloxy, arenesulfonyloxy, alkyl-carbonyloxy (e.g., acetoxy), arylcarbonyloxy, aryloxy, methoxy, N,O-dimethylhydroxylamino, pixyl, and haloformates. In some cases, the leaving group is a sulfonic acid ester, such as toluenesulfonate (tosylate, —OTs), methanesulfonate (mesylate, —OMs), p-bromobenzenesulfonyloxy (brosylate, —OBs), or trifluoromethanesulfonate (triflate, —OTf). In some cases, the leaving group is a brosylate, such as p-bromobenzenesulfonyloxy. In some cases, the leaving group is a nosylate, such as 2-nitrobenzenesulfonyloxy. In some embodiments, the leaving group is a sulfonate-containing group. In some embodiments, the leaving group is a tosylate group. The leaving group may also be a phosphineoxide (e.g., formed during a Mitsunobu reaction) or an internal leaving group such as an epoxide or cyclic sulfate. Other non-limiting examples of leaving groups are water, ammonia, alcohols, ether moieties, thioether moieties, zinc halides, magnesium moieties, diazonium salts, and copper moieties. In certain embodiments, the leaving group is an activated substituted hydroxyl group (e.g., —OC(═O)SRaa, —OC(═O)Raa, —OCO2Raa, —OC(═O)N(Rbb)2, —OC(═NRbb)Raa, —OC(═NRbb)ORaa, —OC(═NRbb)N(Rbb)2, —OS(═O)Raa, —OSO2Raa, —OP(Rcc)2, —OP(Rcc)3, —OP(═O)2Raa, —OP(═O)(Raa)2, —OP(═O)(ORcc)2, —OP(═O)2N(Rbb)2, or —OP(═O)(NRbb)2, wherein Raa, Rbb, and Rcc are as defined herein).
  • The term “pharmaceutically acceptable salt” refers to those salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue toxicity, irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. For example, Berge et al., describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of this disclosure include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable, nontoxic acid addition salts are salts of an amino group formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid or with organic acids such as acetic acid, oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid or by using other methods known in the art such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, picrate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate salts, and the like. Salts derived from appropriate bases include alkali metal, alkaline earth metal, ammonium, and N+(C1-4 alkyl)4 salts. Representative alkali or alkaline earth metal salts include sodium, lithium, potassium, calcium, magnesium, and the like. Further pharmaceutically acceptable salts include, when appropriate, nontoxic ammonium, quaternary ammonium, and amine cations formed using counterions such as halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate, and aryl sulfonate.
  • The term “solvate” refers to forms of the compound, or salt thereof, that are associated with a solvent, usually by a solvolysis reaction. This physical association may include hydrogen bonding. Conventional solvents include water, methanol, ethanol, acetic acid, DMSO, THF, diethyl ether, and the like. The compounds described herein may be prepared, e.g., in crystalline form, and may be solvated. Suitable solvates include pharmaceutically acceptable solvates and further include both stoichiometric solvates and non-stoichiometric solvates. In certain instances, the solvate will be capable of isolation, for example, when one or more solvent molecules are incorporated in the crystal lattice of a crystalline solid. “Solvate” encompasses both solution-phase and isolatable solvates. Representative solvates include hydrates, ethanolates, and methanolates.
  • The term “hydrate” refers to a compound that is associated with water. Typically, the number of the water molecules contained in a hydrate of a compound is in a definite ratio to the number of the compound molecules in the hydrate. Therefore, a hydrate of a compound may be represented, for example, by the general formula R.x H2O, wherein R is the compound, and x is a number greater than 0. A given compound may form more than one type of hydrate, including, e.g., monohydrates (x is 1), lower hydrates (x is a number greater than 0 and smaller than 1, e.g., hemihydrates (R.0.5H2O)), and polyhydrates (x is a number greater than 1, e.g., dihydrates (R.2H2O) and hexahydrates (R.6H2O)).
  • The term “tautomers” or “tautomeric” refers to two or more interconvertible compounds resulting from at least one formal migration of a hydrogen atom and at least one change in valency (e.g., a single bond to a double bond, a triple bond to a single bond, or vice versa). The exact ratio of the tautomers depends on several factors, including temperature, solvent, and pH. Tautomerizations (i.e., the reaction providing a tautomeric pair) may catalyzed by acid or base. Exemplary tautomerizations include keto-to-enol, amide-to-imide, lactam-to-lactim, enamine-to-imine, and enamine-to-(a different enamine) tautomerizations.
  • It is also to be understood that compounds 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”.
  • Stereoisomers that are not mirror images of one another are termed “diastereomers” and those that are non-superimposable mirror images of each other are termed “enantiomers”. When a compound has an asymmetric center, for example, it is bonded to four different groups, a pair of enantiomers is possible. An enantiomer can be characterized by the absolute configuration of its asymmetric center and is described by the R- and S-sequencing rules of Cahn and Prelog, or by the manner in which the molecule rotates the plane of polarized light and designated as dextrorotatory or levorotatory (i.e., as (+) or (−)-isomers respectively). A chiral compound can exist as either individual enantiomer or as a mixture thereof. A mixture containing equal proportions of the enantiomers is called a “racemic mixture”.
  • The term “polymorphs” refers to a crystalline form of a compound (or a salt, hydrate, or solvate thereof). All polymorphs have the same elemental composition. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. Recrystallization solvent, rate of crystallization, storage temperature, and other factors may cause one crystal form to dominate. Various polymorphs of a compound can be prepared by crystallization under different conditions.

  • A “kinase” is a type of enzyme that transfers phosphate groups from high energy donor molecules, such as ATP, to specific substrates, referred to as phosphorylation. Kinases are part of the larger family of phosphotransferases. One of the largest groups of kinases are protein kinases, which act on and modify the activity of specific proteins. Kinases are used extensively to transmit signals and control complex processes in cells. Various other kinases act on small molecules such as lipids, carbohydrates, amino acids, and nucleotides, either for signaling or to prime them for metabolic pathways. Kinases are often named after their substrates. More than 500 different protein kinases have been identified in humans. These exemplary human protein kinases include, but are not limited to, salt-inducible kinase (SIK, e.g., salt-inducible kinase 1 (SIK1), salt-inducible kinase 2 (SIK2), salt-inducible kinase 3 (SIK3)).

  • Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions can be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation can be a sterile injectable solution, suspension, or emulsion in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that can be employed are water, Ringer's solution, U.S.P., and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil can be employed including synthetic mono- or di-glycerides. In addition, fatty acids such as oleic acid are used in the preparation of injectables.
  • The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.
  • In order to prolong the effect of a drug, it is often desirable to slow the absorption of the drug from subcutaneous or intramuscular injection. This can be accomplished by the use of a liquid suspension of crystalline or amorphous material with poor water solubility. The rate of absorption of the drug then depends upon its rate of dissolution, which, in turn, may depend upon crystal size and crystalline form. Alternatively, delayed absorption of a parenterally administered drug form may be accomplished by dissolving or suspending the drug in an oil vehicle.
  • Compositions for rectal or vaginal administration are typically suppositories which can be prepared by mixing the conjugates described herein with suitable non-irritating excipients or carriers such as cocoa butter, polyethylene glycol, or a suppository wax which are solid at ambient temperature but liquid at body temperature and therefore melt in the rectum or vaginal cavity and release the active ingredient.
  • Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In such solid dosage forms, the active ingredient is mixed with at least one inert, pharmaceutically acceptable excipient or carrier such as sodium citrate or dicalcium phosphate and/or (a) fillers or extenders such as starches, lactose, sucrose, glucose, mannitol, and silicic acid, (b) binders such as, for example, carboxymethylcellulose, alginates, gelatin, polyvinylpyrrolidinone, sucrose, and acacia, (c) humectants such as glycerol, (d) disintegrating agents such as agar, calcium carbonate, potato or tapioca starch, alginic acid, certain silicates, and sodium carbonate, (e) solution retarding agents such as paraffin, (f) absorption accelerators such as quaternary ammonium compounds, (g) wetting agents such as, for example, cetyl alcohol and glycerol monostearate, (h) absorbents such as kaolin and bentonite clay, and (i) lubricants such as talc, calcium stearate, magnesium stearate, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof.

  • Methods of Treatment
  • The present disclosure provides methods for the treatment and prevention of inflammatory bowel disease (IBD) and graft-versus-host disease (GVHD).
  • Recent research has established a rationale for modulating IL-10 (e.g., increasing) in both IBD and GVHD. Although the etiology of IBD is complex, impaired function of anti-inflammatory immune mechanisms is observed in many patients. For instance, single nucleotide polymorphisms (SNPs) in genetic loci containing IL10 or its receptor (IL10RA) are associated with an increased risk of Crohn's disease and ulcerative colitis, and rare loss-of-function mutations in the coding regions of IL10 or IL10RA lead to severe, pediatric-onset enterocolitis. The link between gut inflammation and defective IL-10 signaling in humans is recapitulated in Il10−/− and Il10ra−/− mice, which both develop spontaneous colitis. Conversely, prophylactic administration of recombinant IL-10 partially alleviates gut inflammation and weight loss in murine models of chemically induced colitis. Unfortunately, well-tolerated doses of recombinant IL-10 therapy did not show efficacy in clinical trials for Crohn's disease. Potential explanations of this lack of efficacy include insufficient delivery of IL-10 to the gut mucosa by systemic administration and/or the need to combine IL-10 supplementation with neutralization of inflammatory cytokines. Of note, disease activity is reduced in Crohn's disease patients following oral administration of L. lactis engineered to express IL-10, which suggests that specifically increasing IL-10 levels in the gut microenvironment can be therapeutically beneficial in the absence of toxicities (e.g., headache, anemia and thrombocytopenia) that limit systemic treatment.
  • As with IBD, recent research has also established a compelling rationale for treating GVHD by enhancing IL-10. For example, certain IL-10 promoter-region halotypes had a protective effect against GVHD. Recipients of allogenic bone marrow who have the interleukin-10 (IL-10)-592A/A genotype (having high level of IL-10 production) have a lower risk of severe acute GVHD than recipients who have the -592C/C genotype. Studies using IL-10-deficient donor or host mice (BALB/c or C57BL/6, respectively) in a MHC-mismatched model for acute GVHD, found a strongly aggravated course of the disease with increased mortality when either donor or host cells could not produce IL-10. Notably, IL-10 is a potent suppressor of TNF-a, interleukin-1a, interleukin-1b, interleukin-6, interleukin-12, and interferon-gamma production and may facilitate the induction of tolerance after allogeneic transplantation. Indeed, clinical studies suggest that elevated levels of endogenous IL-10 may be associated with immunologic tolerance. These observations underscore the utility and therapeutic potential of enhancing IL-10 production in both IBD (e.g., Crohn's disease and ulcerative colitis) and GVHD.
  • The present disclosure is based in part on the discovery that inhibiting salt-inducible kinases (SIKs) using the SIK inhibitors described herein enhanced IL-10 production by macrophages and dendritic cells of the gut.
  • In another aspect, the present disclosure provides methods of inhibiting the activity of a salt-inducible kinase (SIK) in a subject or cell. In certain embodiments, the SIK is a member of the serine/threonine SIK kinase subfamily (e.g., SIK1, SIK2, SIK3). In certain embodiments, the activity of a SIK in a subject or cell is inhibited by the SIK inhibitors or pharmaceutical compositions described herein. In certain embodiments, the activity of a SIK in a subject or cell is inhibited by the methods described herein by at least about 10%, at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, or at least about 95%.

Combinations of the above-referenced ranges (e.g., at least about 10% and at most about 50%) are also within the scope of the disclosure. Other ranges are also possible. In some embodiments, the activity of a SIK in a subject or cell is selectively inhibited by the methods described herein. In certain embodiments, a SIK is inhibited by a method described herein to a greater extent, compared to a protein kinase that is not a SIK. In certain embodiments, a SIK (e.g., SIK1, SIK2, or SIK3) is inhibited by a method described herein to a greater extent, compared to a different SIK. In certain embodiments, SIK1 is selectively inhibited by the methods described herein, compared to SIK2, SIK3, or a protein kinase that is not a SIK. In certain embodiments, SIK2 is selectively inhibited by the methods described herein, compared to SIK1, SIK3, or a protein kinase that is not a SIK. In certain embodiments, SIK3 is selectively inhibited by the methods described herein, compared to SIK1, SIK2, or a protein kinase that is not a SIK. In some embodiments, the activity of a SIK in a subject or cell is non-selectively inhibited by the methods described herein. In certain embodiments, the level of interleukin 10 (IL-10) is reduced. In certain embodiments, the level of IL-10 is reduced by at least about 10%, at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, or at least about 95%. In some embodiments, bone marrow derived cells (BDMCs) are converted to an anti-inflammatory phenotype. For example, the BDMCs produce reduced levels of pro-inflammatory cytokines (e.g., IL-1β, IL-6, IL-12 and TNF-α). In some embodiments, the BDMCs are macrophages or dendritic cells.

  • Example 2. Materials and Methods Involved in Examples 3 to 24
  • Bone marrow-derived DCs were differentiated from C57BL/6 bone marrow in the presence of GM-CSF-conditioned media. CD11c+CX3CR1hi myeloid cells and CD11c+CX3CR1 DCs were isolated from the small intestine lamina propria of Cx3cr1eGFP/+ mice (12). Detection of cell-surface Thy1.1 expression on BMDCs from 10BiT reporter mice was conducted as described previously (24). Cell viability was estimated by change in total cellular ATP levels using CellTiterGlo assays (Promega). Preparation of recombinant SIK proteins and IC50 measurements were conducted as described previously (21). Total RNA was extracted using a NucleoSpin 96 RNA isolation kit (Macherey-Nagel) followed by cDNA synthesis and multiplex RT-PCR using a microfluidic dynamic array (Fluidigm). The concentrations of TNF-α, IL-6, IL-10, IL-12p40, IL-1β and RANTES in culture supernatants were detected using a FlexSet Cytometric bead array (BD Biosciences). Alternatively, IL-10 secretion was quantified using ELISA (BD Biosciences) or AlphaLISA (PerkinElmer) assays. NO production was estimated based on nitrate content in culture medium using the Greiss reagent.
  • Example 3. Protein Kinase Assays of the SIK Inhibitors
  • In another set of experiments, the activities of the SIK inhibitors described herein against SIK were determined according to the methods reported in Hastie et al., Nature Protocols, 2006, 1, 968-971.
  • Materials
  • Enzyme Dilution Buffer.
  • This buffer consisted of 50 mM Tris-HCl, pH 7.5, 0.1 mM EGTA, 1 mg ml−1 bovine serum albumin and 0.1% (vol/vol) 2-mercaptoethanol.
  • 10× Concentrated Assay Buffer.
  • An assay buffer of 500 mM Tris-HCl, pH 7.5, 1 mM EGTA, and 100 mM magnesium acetate was used for the protein kinase assay. In some cases, the pH of the buffer was changed (e.g., phosphorylase kinase had an optimum pH of 8.6).
  • 1 mM [γ-32P] ATP.
  • The specific activity of the [γ-32P] ATP solution was 1×105 to 1×106 c.p.m. per nmol depending on what was needed to produce an optimal signal/noise ratio. Stocks of nonradioactive (“cold”) ATP were dissolved in 10 mM HEPES, and the pH of the resulting stock solutions was adjusted to 7.4. To measure the concentration of ATP, a sample of such a stock solution was diluted to 20 μM, and the absorbance of the diluted sample was measured at 259 nm. The absorbance of a 20-μM stock solution of ATP at 259 nm was about 0.31. The 1-mM solution of cold ATP was “spiked” with [γ-32P] ATP to produce a radioactivity of 1×105 to 1×106 c.p.m. per nmol.
  • Procedure
  • 1) The number of assay samples needed was determined based on, e.g., the following considerations: (i) each condition was assayed in duplicate; (ii) two controls containing peptide or protein substrate and ATP but no SIK were included to assess contamination by any free ATP not incorporated into substrate, alongside two controls lacking a peptide or protein substrate but containing ATP and SIK to correct for any incorporation of phosphate into the kinase itself (e.g., autophosphorylation); and (iii) a maximum of 40 samples were assayed manually at one time by a single person. Microcentrifuge tubes were label distinctly and were placed on ice.
  • 2) Suspend a wire mesh basket in a beaker containing a magnetic stir bar and not less than 5 ml of 75 mM phosphoric acid per assay sample or a minimum volume of 100 ml. Place this on a magnetic stirrer behind a plexiglass shield.
  • 3) Label 2 cm×2 cm squares of phosphocellulose paper corresponding to the samples to be pipetted into each microcentrifuge tube. Label the phosphocellulose paper using pencil, which was not affected by the solvents used to wash the papers at the end of the assay.
  • 4) Dilute the SIK in enzyme dilution buffer and place on ice.
  • 5) Pipette 5 μl of 10× concentrated assay buffer, 5 μl peptide or protein substrate (the two “no-substrate” control tubes had 5 μl water added instead of peptide or protein substrate), and 30 μl distilled water into each tube. Keep the tubes on ice.
  • 6) Add 5 μl diluted SIK to each tube, except for the two “no-enzyme” control tubes, which had 5 μl enzyme dilution buffer added, and still keeping the tubes on ice. In some cases, premixed “cocktails” of assay components were prepared containing peptide or protein substrate, assay buffer, and distilled water to limit the number of additions to each assay tube.
  • Each of steps 7 to 14 was done behind a plexiglass shield.
  • 7) Insert each tube into the water bath at intervals of 15 s to allow the assay mixture to reach 30° C. Begin the SIK reactions by adding 5 μl of 1 mM [γ-32P] ATP to each tube at intervals of 15 s. Close each tube, vortex for 1 s to mix the contents and immediately replace in a rack in the water bath. Incubate for 10 min at 30° C.
  • 8) At 10 min after the addition of ATP, remove each tube from the water bath at intervals of 15 s.
  • 9) “Spot” 40 μl of each reaction mixture onto the center of a 2-cm square of P81 phosphocellulose paper using forceps to handle the paper squares. Immediately immerse the paper into the 75 mM phosphoric acid contained in the wire mesh basket suspended in the beaker that is being stirred continuously with a magnetic stirrer. This was be done within 1 to 2 s, as this step terminated the reaction.
  • 10) After 5 min, remove the wire mesh basket from the beaker, and discard the phosphoric acid in the beaker and replace it with fresh phosphoric acid. Replace the wire mesh basket in the beaker and repeat this washing procedure three times (with 5 min between each wash). This step removes the [γ-32P] ATP that has not been incorporated into the peptide or protein substrate.
  • 11) After the final wash in phosphoric acid, rinse the papers briefly with acetone to remove the phosphoric acid and either air-dry or dry with a hair dryer.
  • 12) Transfer each paper to a new, distinctly labeled, 1.5-ml microcentrifuge tube.
  • 13) Measure radioactivity in the samples by Cerenkov counting (e.g., without liquid scintillation fluid) in a liquid scintillation counter using a “32P program”. Also measure the radioactivity of 1-μl aliquots of the stock of 1 mM [γ-32P] ATP in triplicate to determine the specific radioactivity of the ATP in terms of c.p.m. per nanomol ATP (1 μl of 1 mM ATP corresponds to 1 nmol ATP).
  • 14) Calculate the activity of the SIK. One unit (U) of SIK activity is that amount that catalyzes the incorporation of 1 nmol phosphate into the standard peptide or protein substrate in 1 min. In the assay described herein, the activity of the undiluted SIK solution in U ml−1 is [(r−b/sa)×d×1.25×200]/10, where r is the c.p.m. incorporated into the substrate in the SIK reaction, b is the average c.p.m. associated with the phosphocellulose paper in the reaction “blanks”, sa is the specific radioactivity of the ATP (c.p.m. nmol), d is the “fold dilution” of the SIK before assay, 1.25 is a correction for transfer of only 80% of the reaction to the phosphocellulose paper (40 μl of a 50-μl assay volume), 200 corrects for the addition of only 5 μl of diluted SIK to each assay, and 10 is the incubation time in min. In some cases, if the protein concentration of the assay was known, the activity was converted from U ml−1 to U mg−1 of protein.
  • In some experiments of determining the inhibitory activities of a SIK inhibitor described herein against SIK (e.g, experiments yielding the data in Table 3), DMSO was used as a control. The activity of a SIK when treated with DMSO, but not with a SIK inhibitor described herein, was set to 100%. SIK inhibitors resulting in less than 100% activity of a SIK are deemed to be inhibitors of the SIK.
  • Results
  • Exemplary results of the protein kinase assays of the SIK inhibitors described herein are shown in Table 3.

  • Example 4. Molecular Biology Methods
  • The lentiviral luciferase reporter construct for the cAMP-responsive transcription factor CREB was created by combining the pLenti7.3/V5-DEST vector from Life Technologies (Cat # V534-06), the minimal promoter and luc2P open reading frame from Promega's pGL4.29 [luc2P/CRE/Hygro], and an optimized synthetic cAMP-regulated enhancer that contains multiple nonoverlapping binding sites for CREB (Melnikov A, et al. (2012) Systematic dissection and optimization of inducible enhancers in human cells using a massively parallel reporter assay. Nature biotechnology 30(3):271-277). The CMV-Gateway-V5 stretch from pLenti7.3/V5-DEST was removed by digestion with BspDI and Mlul. The minimal promoter and luc2P open reading frame of pGL4.29 was PCR amplified with Gibson cloning complementary sequence to the digested pLenti7.3/V5-DEST backbone using the primer pair: F_TTCAAAATTTTATCGATCGCACCAGCGTGTGGATCCGAGAACAGATCTGGCCT CGG, R_ACTAACCGGTACGCGTTCTAGAGTCGCGGCCTTAGAC. Clontech's Infusion enzyme mix (Cat #638916) was used to insert the minimal promoter and luc2P into the digested pLenti7.3/V5-DEST. The synthetic cAMP-regulated enhancer ACACCAGACATTGACGTAAGCTGCCAGATCCCATTCCCGTCATACTCTGACGTCT TTCAGACACCCCATTGACGTCAATGGGAGAAC was synthesized as a standard desalted Ultramer from Integrated DNA Technologies and made double stranded with HercII fusion polymerase (Agilent) and Gibson cloning complementary sequence using the primer pair: F_GCACCAGCGTGTGGATC, R_GCCAGATCTGTTCTCGGATC. The pLenti7.3 backbone containing a minimal promoter and luc2P was then digested with BamHI and the synthetic cAMP-regulated enhancer was inserted in front of the minimal promoter using Infusion enzyme mix (Clontech). pLKO shRNAs targeting CRTC3 (TRCN0000241211 or TRCN0000241214), RFP (TRCN0000072206) or LacZ (TRCN0000072256) were obtained from the Broad Institute's Genetic Perturbation Platform. For production of lentiviral particles, 293T cells were transfected with the CREB lentiviral reporter construct or pLKO shRNA plasmids and packaging plasmids dR8.91 and VSV-G using Lipofectamine 2000. The 293T media was changed 24 hr post-transfection to DMEM+30% FBS and Pen/Strep. Media containing lentiviral particles was collected 48 hr post-transfection and stored at −80° C.
  • Example 5. Mouse Models
  • C57BL/6 and Balb/c mice were obtained from Jackson Laboratory. CX3CR1GFP/+ and 10BiT mice have been described previously (Jung S, et al. (2000) Analysis of fractalkine receptor CX(3)CR1 function by targeted deletion and green fluorescent protein reporter gene insertion. Molecular and cellular biology 20(11):4106-4114; Maynard C L, et al. (2007) Regulatory T cells expressing interleukin 10 develop from Foxp3+ and Foxp3− precursor cells in the absence of interleukin 10. Nature immunology 8(9):931-941). Mouse maintenance and cell isolation was performed under protocols approved by the Massachusetts General Hospital Subcommittee on Research Animal Care (SRAC), in conformance with the National Institutes of Health Guide for the Care and Use of Laboratory Animals.
  • Example 6. Bone Marrow-Derived Cell Culture Methods
  • C57BL/6 mice were euthanized and bone marrow harvested from femurs and tibias as described previously (Graham D B, et al. (2007) An ITAM-signaling pathway controls cross-presentation of particulate but not soluble antigens in dendritic cells. The Journal of experimental medicine 204(12):2889-2897). BMDCs were differentiated DMEM supplemented with 2 mM GlutaMAX, 10% (vol/vol) FBS, penicillin, streptomycin and 2% mouse GM-CSF conditioned media derived from TOPO cells. Cultures were differentiated for 7 days and routinely analyzed for >90% CD11c (APC anti-CD11c clone HL3; BD Biosciences) positivity by flow cytometry before use in experiments. Lentiviral transduction of bone marrow cultures was conducted by addition of 293T culture supernatants containing lentiviral particles encoding the CREB dependent luciferase reporter construct or CRTC3 targeting or control shRNAs one day post-isolation. Stable integration of lentiviral shRNA constructs was selected by addition of puromycin (3 μg/mL) on day 4 post-transduction. After 2 days, stably transduced BMDCs were released from selection and used in subsequent assays. Unless otherwise indicated, cells were treated for 2 days with PGE2 (5 μM) or HG-9-91-01 (0.5 μM) or an equivalent concentration of DMSO (<0.5%) and then stimulated for 18 hr with LPS (100 ng/mL), R848 (10 μg/mL) or zymosan (4 μg/mL).
  • Example 7. Human Myeloid Cell Culture Methods
  • Heparinized blood from healthy donors was obtained from Research Blood Components. Peripheral blood mononuclear cells (PBMCs) were obtained by density centrifugation of blood diluted 50% (vol/vol) with PBS over Ficoll-Paque (Pharmacia Biotech). PBMCs were further purified by plastic adherence for 1 hr and washed 5× with PBS. Monocytes within the PBMC pool were differentiated towards DCs in X-VIVO media (Lonza) supplemented with IL-4 (50 ng/mL, R&D Systems) and GM-CSF (50 ng/mL, R&D Systems) or macrophages in X-VIVO media supplemented with GM-CSF (5 ng/mL) and IFN-γ (5 ng/mL; PeproTech) for 7 days as described previously (Smeekens S P, et al. (2013) Functional genomics identifies type I interferon pathway as central for host defense against Candida albicans. Nature communications 4:1342). After third day, half of the culture medium was replaced by fresh DC/macrophages differentiation medium.
  • Example 8. Methods of High-Throughput Detection of IL-10 Up-Regulation and Cell Viability
  • BMDCs were seeded into black 384-well plates (Corning) at 20,000 cells/well in 40 μL complete DMEM using a Multidrop COMBI (Thermal Scientific) followed by incubation at 37° C. for 2 hr to allow for plate adherence. SIK inhibitors (100 nL/well) were pin-transferred from concentrated DMSO stocks using CyBi-Well Vario (CyBio) into duplicate plates. For each treatment plate, 32 out of 384 wells were pinned with DMSO as negative control and 32 out of 384 wells were pinned with PGE2 (5 μM final concentration). Two days after SIK inhibitor treatment, BMDCs were stimulated with zymosan (4 μg/mL final concentration) dispersed in culture medium (20 μL/well) using a Multidrop COMBI. After 18 hr, 5 μL of resulting supernatant was transferred from the culture plate to white 384-well AlphaLISA plates (Perkin Elmer) using a CyBi-Well Vario. IL-10 abundance in the supernatants was determined using an AlphaLISA assay (PerkinElmer) according to the manufacture's protocol and signal intensity measured using an EnVision multimode plate reader. SIK inhibitor activity was expressed as a % of the differences between the mean abundance of IL-10 in PGE2 versus DMSO wells on a per plate basis. Cell viability assays were conducted on the same tissue culture plates as the IL-10 assay. First media was removed and replaced by solution of 50% (vol/vol) CellTiter-Glo (Promega) in PBS. Luminescence was read using an Envision multimode plate reader, and signal intensity calculated relative to DMSO control wells on a per plate basis.
  • Example 9. Reporter Gene Assay Methods
  • Six days post transduction with lentiviral particles encoding the CREB-luciferase reporter construct, BMDCs were seeded into black 384-well plates (Corning) at 20,000 cells/well in 40 μL complete DMEM using a Multidrop COMBI (Thermal Scientific) followed by incubation at 37° C. for 2 hr to allow for plate adherence. SIK inhibitors (100 nL/well) or DMSO (vehicle) were pin-transferred from concentrated DMSO stocks using CyBi-Well Vario (CyBio) into triplicate plates. After incubation with SIK inhibitors for 24 hr, BMDCs were stimulated with zymosan (4 μg/mL) dispersed using a Multidrop COMBI. After 5 hr, media was removed and replaced by solution of 50% (vol/vol) Steadylite Plus (PerkinElmer) in PBS and incubated at room temperature for 10 min. Luminescence was read using an Envision multimode plate reader, and SIK inhibitor activity was expressed fold DMSO treated wells on per plate basis.
  • Example 10. Methods of Detecting il10-Thy1.1 Reporter Gene
  • Preparation of BMDCs from 10BiT reporter mice expressing an il10-Thy1.1 transgene, SIK inhibitor treatment and zymosan stimulation was conducted as described above. After 18 hr of stimulation, 10BiT BMDCs were collected by scraping, washed with PBS and stained with LIVE/DEADGreen (Invitrogen) to identify viable cells as well as APC anti-Thy1.1 (clone OX-7; BD Biosciences). Stained cells were then fixed with 4% paraformaldehyde and data acquired on a FACSVerse (BD Biosciences).
  • Example 11. Multiplex qPCR Methods
  • Total RNA was extracted using a NucleoSpin 96 RNA isolation kit (Macherey-Nagel). 5 ng of total RNA was used for cDNA synthesis and multiplex RT-PCR using a microfluidic dynamic array (Fluidigm; (Spurgeon S L, Jones R C, & Ramakrishnan R (2008) High throughput gene expression measurement with real time PCR in a microfluidic dynamic array. PloS one 3(2):e1662)). Relative gene expression was calculated from Ct values and normalized against ACTB mRNA levels as described previously (Pfaffl M W (2001) A new mathematical model for relative quantification in real-time RT-PCR. Nucleic acids research 29(9):e45). The fold-change in gene expression induced by SIK inhibitor treatment is reported relative to DMSO-treated samples exposed to the same microbial stimulus unless otherwise indicated. Genes and corresponding primers used in the multiplex qPCR are available in Table 4. The heat map representing multiplex qPCR data was generated for genes with significantly different expression (p<0.5) between DMSO versus PGE2 or HG-9-91-01-treated samples. One-minus Pearson's based hierarchical clustering of gene expression profiles was conducted using the Gene-E software suite (www.broadinstitute. org/cancer/software/GENE-E/download.html).

Briefly, cells were rinsed in ice-cold PBS and extracted in lysis buffer (50 mM Tris•HCl at pH 7.4, 1 mM EDTA, 1 mM EGTA, 50 mM NaF, 10 mM sodium β-glycerol 1-phosphate, 1 mM DTT, 1 mM sodium orthovanadate, 1% (vol/vol) Triton X— 100 and 1× Complete EDTA-free Protease Inhibitor Cocktail (Roche).

  • Example 17. Focused High-Throughput Screen Identifies Kinase Inhibitors that Enhance IL-10 Production by Activated Dendritic Cells
  • To enable measurement of IL-10 production by myeloid cells in high throughput, we established an AlphaLISA-based assay to detect IL-10 released by BMDCs in 384-well plate format (FIG. 1A). Consistent with established role of EP2/EP4 prostanoid receptor signaling in promoting IL-10 expression in myeloid cells (19), differentiation of BMDCs in the presence PGE2 increased levels of IL-10 detectable in the culture media by ELISA following stimulation with a variety of microbial-derived ligands (FIG. 5A). The robust IL-10-potentiating effect of differentiating BMDCs in the presence of PGE2 was recapitulated in fully differentiated BMDCs treated with PGE2 for 2 days prior to stimulation with the yeast cell wall preparation zymosan (FIG. 5B). Moreover, the stimulatory effects of treatment with PGE2 for 2 days on zymosan-induced IL-10 production were observed with BMDCs cultured in 384-well plates using AlphaLISA-based IL-10 detection (FIG. 5C). Together, these results establish zymosan-stimulated BMDCs as a robust, reproducible assay system to identify small-molecules that enhance IL-10 production by activated myeloid cells.
  • To discover novel small-molecule enhancers of IL-10 production by inflammatory DCs, we screened a collection of >150 kinase inhibitors comprising FDA-approved drugs and well-annotated probe compounds for their effects on zymosan-induced IL-10 production in BMDCs (FIG. 5D). Ten kinase inhibitors were classified as hits based on their ability to dose-dependently potentiate IL-10 production with a maximum effect>30% of the PGE2 response (FIG. 1B and FIG. 6). These hits include the GSK-3β inhibitor CHIR-99021, which further validates the screening strategy because pharmacological or genetic disruption of GSK-3P3 has been previously reported to enhance IL-10 production by LPS-stimulated MΦs (17). Several of the IL-10-enhancing compounds reduced IL-10 at concentrations greater than 1 μM, an effect that correlates with reduced viability in the case of bosutinib, saracatinib, TAE-684 and CHIR-99021 (FIG. 6). Alternatively, inhibition of kinases (e.g., Src and Syk) that convey proximal signals downstream of the zymosan receptor Dectin-1 may account for the inhibitory effect on IL-10 production at high concentrations of compound. In these cases, EC50 values were calculated solely using IL-10-potentiating concentrations for each inhibitor.
  • Example 18. Analysis of Shared Targets of Hit SIK Inhibitors Suggests Role for Inhibition Salt-Inducible Kinases in IL-10 Potentiation
  • Dasatinib, bosutinib and saracatinib, which are used clinically to inhibit BCR-Abl, c-Kit and several other kinases for treatment of chronic myeloid leukemia (CML) (22), were among the most potent and active (i.e., large maximum effect) IL-10 enhancers identified in this screen. However, the BCR-Abl-targeting CML drug imatinib was non-toxic in BMDCs, but did not up-regulate IL-10 production (FIG. 6). This contrast suggests that the observed IL-10-potentiating effects of the hit SIK inhibitors might arise from shared ‘off-target’ inhibition of kinases other than Abl1. This possibility is supported by kinase-profiling data indicating that dasatinib and bosutinib modulate the activity of a large number of kinases (23). To investigate this possibility, we correlated the IL-10-potentiating activity of 38 of the screened kinase inhibitors, including six of the hit SIK inhibitors, with publically available binding affinities (Kd's) for a panel of >400 recombinant kinases (23). Fisher-Exact testing was used to determine whether high affinity ligands of a particular kinase, defined as SIK inhibitors with Kd<500 nM, were enriched among the hit SIK inhibitors. This analysis identified statistically significant associations (p<0.05) between IL-10 up-regulation and binding to several kinases (FIG. 1C). However, due to the small number of SIK inhibitors with available kinase profiling data and large number of tests, none of the associations remained significant after correction for multiple hypothesis testing.
  • SIK1 and SIK2 were enriched among the high-affinity targets of the IL-10-potentiating kinase inhibitors (FIG. 1C), which is consistent with the IL-10-potentiating effects of SIK inhibition in activated MΦs (20, 21). In agreement with these reports, pre-treating BMDCs with HG-9-91-01, a recently described inhibitor of SIK1-3, along with several other kinases (21), results in concentration-dependent potentiation of zymosan-induced IL-10 production with an EC50≈200 nM and a maximum effect similar to that observed with PGE2 (FIG. 1D). Similar to our observations with dasatinib and bosutinib, concentrations of HG-9-91-01 greater than 1 μM suppressed zymosan-induced IL-10 production. This decrease in IL-10 secretion does not correlate with reduced viability (FIG. 2A), suggesting that it may instead result from inhibition of additional kinase targets mediating the effects of zymosan stimulation. For example, HG-9-91-01 potently inhibits Src with less than 4% activity remaining at 1 μM (21). As with PGE2, extended pre-incubation of BMDCs with HG-9-91-01 was required for robust up-regulation of IL-10 in response to stimulation with zymosan, LPS or the viral RNA mimetic R848 (FIGS. 7A to 7C). To determine if SIK inhibition increases the fraction of cells producing IL-10, BMDCs derived from transgenic mice in which the Il10 promoter drives expression of Thy1.1 (‘10BiT’ reporter (24)) were treated with HG-9-91-01 for 2 days prior to stimulation with zymosan for 18 hr and immunostaining for cell surface Thy 1.1 (FIG. 1E). In this assay system, SIK inhibition enhanced the fraction of BMDCs expressing Il10 following zymosan stimulation more than 5-fold (FIG. 1F). Collectively, these results suggest that SIK inhibition underlies the IL-10-potentiating activity of several of the hit SIK inhibitors identified in this screen by enhancing the fraction of activated dendritic cells that produce IL-10 in response to microbial stimulation.
  • Example 19. FDA-Approved CML Drugs Up-Regulate IL-10 Production by a Mechanism Involving Enhanced CRTC3/CREB Signaling
  • Potent binding to SIK1 and SIK2 by dasatinib, bosutinib and the annotated Alk inhibitor TAE-684 (Kd<30 nM in all cases (23)) contributes to the positive correlation between SIK inhibition and IL-10 potentiation. Based on the kinase profiling data, we then studied whether dasatinib and bosutinib, as representative hits, induced cellular effects consistent with up-regulation of IL-10 production via the SIK2/CRTC3/CREB pathway. In support of this hypothesis, pre-incubation of BMDCs with dasatinib or bosutinib resulted in a four-fold induction of a CREB-dependent luciferase reporter construct following zymosan stimulation (FIG. 8A). In addition, as reported for HG-9-91-01 (21), bosutinib treatment is associated with a decrease in SIK-specific phosphorylation of CRTC3 at S370 with an EC50 similar to that observed for up-regulation of CREB transcriptional activity and IL-10 production (FIG. 8B). Finally, abundance of CRTC3 protein was reduced to nearly undetectable levels in BMDCs stably transduced with shRNAs targeting its transcript to test whether the IL-10-potentiating effects of dasatinib and bosutinib require functional CREB/CRTC3 complexes (FIG. 8C). In support of this hypothesis, CRTC3 knockdown significantly reduced the maximum IL-10 enhancement induced by both dasatinib and bosutinib relative to control shRNAs targeting RFP or LacZ (FIGS. 8D and 8E). Together, these biochemical and cellular data support a model where enhancement of CREB/CRTC3 signaling following SIK inhibition mediates the IL-10-potentiating activity of dasatinib, bosutinib and potentially other FDA-approved multi-kinase inhibitors.
  • Example 20. Activity of HG-9-91-01 Analogs Suggests Specific Role of SIK2 Inhibition in IL-10 Potentiation
  • HG-9-91-01 potently inhibits SIK1-3 (IC50<20 nM (21)) making it challenging to determine how inhibiting particular SIK isoforms contributes to IL-10 up-regulation in activated DCs. This question was addressed by determining how modifying the structure of HG-9-91-01 affects IL-10 potentiation relative to inhibition of SIK1-3. To do so, we first developed a succinct, modular synthesis of HG-9-91-01 and related analogs bearing substitutions of the central heteroaromatic core (FIG. 9A). This series of SIK inhibitors was then tested for their effects on SIK1-3 activity as well as IL-10 production by and viability of zymosan-stimulated DCs (FIG. 2A and FIG. 9B). Despite displaying a range of EC50's for IL-10 up-regulation, these SIK inhibitors were all potent inhibitors of SIK1 such that the two activities appear to be uncorrelated (FIG. 2B). In contrast, SIK inhibitors lacking the 2,4-dimethoxy aniline moieties and/or bearing alterations to the central heteroaromatic core of HG-9-91-01 had differentially reduced potencies of SIK2 and SIK3 inhibition (FIG. 2B). Comparing the EC50 values for IL-10 induction versus the IC50's for SIK2 or SIK3 inhibition for the five SIK inhibitors retaining the phenyl piperazine moiety revealed a significant (R2=0.92) positive correlation between the potency of SIK2 inhibition and IL-10 induction, whereas this trend was less pronounced for SIK3 (FIG. 2B). Several SIK inhibitors in this series displayed toxicity at concentrations greater than 1 μM (FIGS. 2A and 9B). However, consistent with data indicating that reduction of Sik2 expression by RNAi is well tolerated in macrophages (21), the toxicity of HG-9-91-01 analogs did not correlate with the IC50's for SIK1-3 inhibition. The close correlation between the potencies of SIK2 inhibition and IL-10 up-regulation suggest that inhibition of this SIK isoform is primarily responsible for the IL-10-potentiating activity of HG-9-91-01 and structurally related SIK inhibitors in activated dendritic cells.
  • Example 21. SIK Inhibition Converts Activated Myeloid Cells to an Anti-Inflammatory State
  • To test whether SIK inhibition promotes anti-inflammatory phenotypes beyond enhanced IL-10 production, we pre-treated BMDCs with concentrations of HG-9-91-01 or PGE2 that equivalently up-regulate IL-10, and measured the abundance of 100 transcripts encoding key myeloid cytokines and transcriptional regulators after 4 hr stimulation with LPS, R848 or zymosan (FIG. 3A). Transcriptional responses to PGE2 or HG-9-91-01 were normalized to vehicle-treated samples for each activating stimuli, and significantly induced or repressed genes (p<0.05) were clustered using One-minus Pearson's correlations (FIG. 3A). While IL-10 mRNA levels were robustly enhanced by both PGE2 and HG-9-91-01 (FIG. 10A), notable differences are observed in the transcriptional response to these two CREB activating stimuli. Expression of the pro-inflammatory cytokines Il12b and Il1b were significantly elevated in PGE2- versus HG-9-91-01-treated BMDCs (FIGS. 10B and 10C) and similar trends were observed with Il23a and Il33 (FIGS. 10D and 10E). Similarly, abundance of Arg and Nos2 transcripts, which encode genes essential arginine catabolism and nitric oxide (NO) production, respectively, were highly induced by PGE2, while these changes were significantly blunted in BMDCs pre-treated with HG-9-91-01 (FIGS. 10F and 10G).
  • Next, we asked how the differential transcriptional responses activated by PGE2 versus SIK inhibition translate into production NO and inflammatory cytokines. While IL-10 secretion was similarly induced in BMDCs pre-treated with PGE2 or HG-9-91-01 before stimulation with LPS, R848 or zymosan, production of several pro-inflammatory mediators was significantly different (FIG. 3B). For instance, production of IL-12p40 and TNF-α was suppressed to a significantly greater extent by treatment with HG-9-91-01 rather than PGE2 regardless of activating stimuli. More strikingly, IL-1β production was enhanced by PGE2 following stimulation with R848 or zymosan, while production of this pro-inflammatory cytokine was suppressed in the presence of the SIK inhibitor. Lastly, elevated expression of Nos2 in PGE2-treated BMDCs relative to HG-9-91-01-treated BMDCs correlated with increased NO production following zymosan stimulation. Consistent with the effects of SIK inhibition in BMDCs, pre-incubating human MΦs or DCs with HG-9-91-01 enhanced IL-10 production while dramatically reducing IL-12p70 secretion in response to zymosan stimulation (FIGS. 11A and 11B). Hence, SIK inhibition converts human and murine myeloid cells to an anti-inflammatory phenotype in which up-regulation of IL-10 is accompanied by reduced secretion of inflammatory cytokines. Moreover, the stimulatory effect of SIK inhibition on several inflammatory mediators is substantially blunted relative to the responses induced by PGE2.
  • Example 22. SIK Inhibition does not Enhance IL-10 Production by Regulatory T Cells Subsets
  • Regulatory CD4+ T cells expressing the master transcription factor FoxP3 (i.e., Treg's) play an essential role in maintaining tolerance to self and commensal antigens (25). In addition, a subset of FoxP3 CD4+ T cells that produce high levels of IL-10, termed type 1 regulatory (Tr1) cells, have been implicated in gut immune homeostasis (26). To determine if SIK inhibition affects differentiation and/or IL-10 production by either regulatory T cell subset, we treated naïve splenic CD4+ T cells with HG-9-91-01 in the presence of culture conditions that promote Treg or Tr1 differentiation for 4 days. In contrast to myeloid cells, concentrations of HG-9-91-01 greater than 0.5 μM were toxic in both Treg's and Tr1 cells (FIGS. 12A and 13A). Differentiation of Treg's in the presence of concentrations of HG-9-91-01 sufficient to potently inhibit SIKs and increase IL-10 in BMDCs did not increase the fraction of Foxp3+ cells or promote IL-10 secretion (FIGS. 12B and 12C). Similarly, although Tr1 cells abundantly secreted IL-10, this activity was not further enhanced by non-toxic concentrations of HG-9-91-01 (FIG. 13B). Together, these data suggest that SIK/CRTC/CREB signaling may play a greater role in regulating Il10 expression in myeloid cells than T lymphocytes.
  • Example 23. SIK Inhibition Enhances IL-10 Production by Immunoregulatory Gut Myeloid Cells
  • To determine if SIK inhibition enhances IL-10 production by primary myeloid cells from gut tissues, we isolated immunoregulatory CD11c+CX3CR1hi cells and a control population of CD11c+CX3CR1 DCs from the small intestine of Cx3cr1eGFP/+ mice (FIG. 4A). Because ex vivo survival of primary gut cells is limited, both subsets were pre-treated with HG-9-91-01 for 30 min prior to 18 hr stimulation with LPS or zymosan. Despite the limited pre-treatment, HG-9-91-01 enhanced IL-10 production by CD11c+CX3CR1hi cells activated with LPS or zymosan (FIG. 4B). Consistent with our results in BMDCs and human DCs/MΦs, up-regulation of IL-10 was accompanied by reduced secretion of TNF-α in both gut myeloid cell subsets. SIK inhibition does not appear to non-specifically disrupt function of gut DCs/MΦs because production of IL-6 or the IFNγ-responsive chemokine RANTES were not affected by HG-9-91-01 pre-treatment in either subset (FIG. 4B). Thus, the IL-10-potentiating activity of HG-9-91-01 in CD11c+CX3CR1hi myeloid cells isolated from the small intestine provides experimental evidence supporting SIKs as novel target to enhance gut IL-10 levels.
  • Example 24. Discussion of Examples
  • Described herein, is a small-molecule screen that identified SIK inhibition as a common mechanism by which several multi-kinase inhibitors, including FDA-approved drugs for CML, enhance IL-10 production by activated BMDCs. Evaluation of a series of structural analogs of the selective SIK targeting inhibitor HG-9-91-01 demonstrates a strong correlation between the potency of SIK2 inhibition and enhanced IL-10 production. These results, together with data indicating that expression of a HG-9-91-01-resistant SIK2 allele suppresses the IL-10-potentiating effects of this SIK inhibitor in the RAW264.7 murine macrophages (21), suggests that SIK2 plays a primary role in restraining IL-10 production in activated myeloid cells. Along with enhanced IL-10 secretion, SIK inhibition converted activated BMDCs to an anti-inflammatory phenotype marked by reduced secretion of the inflammatory cytokines IL-1β, IL-6, IL-12 and TNF-α, and these coordinated effects of SIK inhibition were conserved in human DCs/MΦs. In addition, we evaluated whether SIK inhibition enhanced IL-10 production in other immune cell types known to produce IL-10 such as FoxP3+ Treg's or Tr1 cells. In contrast to our observations in myeloid cells, treatment with HG-9-91-01 did not increase IL-10 production during ex vivo differentiation of either regulatory T cell subset, which is consistent with studies indicating that c-MAF and mitogen-activated protein (MAP) kinase signaling play a central role in IL-10 regulation in T lymphocytes (16).
  • The results indicate that dasatinib and bosutinib induce effects consistent with SIK inhibition in dendritic cells including activation of a CREB-dependent luciferase reporter construct and reduction of SIK-specific phosphorylation of CRTC3 at S370. Significantly, the IL-10-enhancing activity of both dasatinib and bosutinib in activated BMDCs was blunted by knockdown of CRTC3. Together, these results support a model where SIK inhibition underlies the immunomodulatory effects of these FDA-approved CML drugs in myeloid cells and provide new mechanistic insight into the recent report that dasatinib treatment increased serum IL-10 levels, while decreasing TNF-α, following systemic LPS challenge (27). These findings have several potential implications for therapeutic use of dasatinib and related SIK inhibitors. Dasatinib doses administered to CML patients achieve serum concentrations sufficient to potently inhibit SIKs and to up-regulate IL-10 by activated dendritic cells (28), which suggests that SIK inhibition is unlikely to be toxic and that the IL-10-potentiating activity of FDA-approved drugs targeting these kinases might be explored as candidate treatments for IBD. In the context of cancer, it is possible that elevated serum IL-10 levels mediated by ‘off-target’ SIK inhibition could modulate the chemotherapeutic activity of dasatinib given that T cell-mediated immune responses targeting tumor antigens are a critical component of dasatinib's mode-of-action (29). Therefore, combining dasatinib or related kinase inhibitors with an IL-10 neutralizing strategy might be a rational approach to enhance the chemotherapeutic activity of these SIK inhibitors.
  • The results described herein, provide additional mechanistic insight into the ability of SIK inhibitors to selectively enhance IL-10 production by activated myeloid cells. For instance, key differences in the expression of genes encoding inflammatory cytokines (e.g., Il1b, Il12b and Il23a) or NO production (Nos2) were observed in the transcriptional profiles of BMDCs treated with concentrations of PGE2 or HG-9-91-01 that up-regulate IL-10 to a similar extent. Significantly, these differential transcriptional responses were mirrored by greater suppression of IL-12p40 (i.e., the cytokine encoded by Il12b) secretion and a lack of increased NO production in HG-9-91-01- versus PGE2-treated BMDCs. Reduced induction of Il12b and Il23a expression with HG-9-91-01 is significant because these genes encode the two subunits of IL-23, a heterodimeric cytokine that promotes expansion of the inflammatory TH17 T cell lineage (30). Similarly, while NO plays an essential role in the anti-microbial activity of myeloid cells, aberrantly high production of this inflammatory mediator is thought to contribute to IBD pathogenesis (31). Both SIK inhibition and PGE2 enhance IL-10 transcription by via SIK/CRTC/CREB signaling. However, in the case of EP2/EP4 prostanoid receptors agonists like PGE2, these effects are mediated by activation of PKA following an intracellular cAMP flux. In addition to the PKA/CREB cascade, cAMP activates exchange proteins activated by cAMP (Epac's), which are scaffolding proteins that nucleate MAP kinase and cytoskeletal signaling components (32). Of note, the stimulatory effects of PGE2 on IL-23 and NO production have both been linked to the cAMP/ePac pathways in myeloid cells (19). Hence, our findings extend previous studies of SIK inhibitors by suggesting a model in which SIK inhibition promotes selective enhancement of CREB-dependent Il10 expression in the absence of pleiotropic effects of elevated intracellular cAMP (FIG. 14).
  • In addition to IL-10 and its receptor, SNPs near the genetic loci for PTGER4, which encodes the EP4 prostanoid receptor, and CRTC3 confer increased risk for Crohn's disease and ulcerative colitis (2). In addition, an intronic SNP in the SIK2 confers susceptibility to primary sclerosing cholangitis, a degenerative liver disease that shares significant co-morbidity with IBD (33). These human genetic data potentially implicate EP4/SIK2/CRTC3/CREB signaling as a contributor to IBD (patho)physiology via regulation of gut IL-10 levels, and make it an intriguing target for therapeutic manipulation. This is supported by the efficacy of phosphodiesterase (PDE) inhibitors, which suppress cAMP hydrolysis, and gut restricted delivery of EP4-selective agonists in murine models of colitis (34, 35). Unfortunately, potent emetic effects have hampered therapeutic development of PDE inhibitors (36), while gut-specific activation of prostanoid receptors remains an unproven therapeutic strategy. Specific experimental support for SIK inhibition as a novel IBD treatment comes from our observation that the IL-10-potentiating activity of HG-9-91-01 is maintained in murine CD11c+CX3CR1hi cells, a highly abundant subset of myeloid cells that play a key role in maintaining gut immune homeostasis, isolated from the small intestine (13, 14). The anti-inflammatory activity of CD11c+CX3CR1hi myeloid cells in the CD45RBhi T cell transfer colitis model requires intact IL-10/STAT3 signaling (15), which suggests that SIK inhibition will enhance the T cell suppressive activity of these cells and, in turn, suppress pathogenic auto-inflammation characteristic of IBD.
  • The disclosure reveals that SIK inhibition by small molecules converts activated DCs/MΦs to an anti-inflammatory phenotype characterized by enhanced IL-10 production coupled with reduced secretion of inflammatory cytokines. Integrating genetic analysis of IBD susceptibility with the IL-10-potentiating activity of HG-9-91-01 in primary gut myeloid cells supports SIKs as a potential new target for treatment of these disorders. However, because aberrant recruitment/activation of inflammatory myeloid cells also contributes to the pathogenesis of type-1 diabetes, rheumatoid arthritis and systemic lupus erythematosus (10), SIK inhibition may be a more broadly applicable therapeutic strategy for treatment of autoimmune/auto-inflammatory disorders.
