SUBSTITUTED IMIDAZOPYRIDINYL COMPOUNDS USEFUL AS INHIBITORS OF TLR9 CROSS REFERENCE This application claims the benefit of U.S. Provisional Application Serial No. 63/311,612 filed February 18, 2022 and U.S. Provisional Application Serial No. 63/379,340 filed October 13, 2022, each of which is incorporated herein in its entirety. DESCRIPTION The present invention generally relates to substituted imidazopyridinyl compounds useful as inhibitors of signaling through Toll-like receptor 9 (TLR9). Provided herein are substituted imidazopyridinyl compounds, compositions comprising such compounds, and methods of their use. The invention further pertains to pharmaceutical compositions containing at least one compound according to the invention that are useful for the treatment of conditions related to TLR9 modulation, such as fibrotic diseases, and methods of inhibiting the activity of TLR9 in a mammal. Toll-like receptors (TLRs) are transmembrane proteins having the ability to initiate an inflammatory response upon recognition of pattern-associated molecular patterns (PAMPs) or microbe-associated molecular patterns (MAMPs). A total of 10 human TLRs have been identified and can be located in the cell surface or, as in the case of TLR7, 8 and 9, in the endolysosomes. TLR9 recognizes unmethylated single-stranded DNA containing cytosine-phosphate-guanine (CpG) motifs that are typically found in bacterial and mitochondrial DNA (mtDNA). TLR9 may contribute to fibrogenesis by promoting inflammation via the MyD88-dependent signalling pathway that ultimately mediates activation of IL-6, IFN-α, IL-1β, and TNF-α among others cytokines. (Barton GM, Kagan JC (2009) Nat. Rev. Immunol.9(8), 535–42; Li X, Jiang S, Tapping RI (2010) Cytokine 49(1), 1–9). TLR9 levels are higher in lung biopsies of rapid idiopathic pulmonary fibrosis (IPF) progressors than in the healthy or stable IPF proxressors (Sci. Transl. Med.2010, 2(57):57ra82). Circulating mtDNA, the ligand for TLR9 has recently been identified as a mechanism-based prognostic biomarker of IPF (Am J. Resp. and Crit. Care Med.2017, 196(12), 1502). In addition, it has been observed that TLR9 is up-regulated in human and murine non-alcoholic steatohepatitis (NASH) (Clin. Sci.2017, 131(16), 2145), while hepatocyte mitochondrial DNA drives NASH via activation of TLR9 (J. Clin. Inv.2016, 126(3), 859. Accordingly, inhibitors/antagonists of TLR9 are predicted to have efficacy as novel therapeutic agents to treat fibrotic diseases. TLR9 inhibition has been recognized as a potential route to therapies for fibrotic diseases including idiopathic pulmonary fibrosis (Trujillo et al. Sci. Transl. Med.2010, 2(57):57ra82; Yoshizaki et al. Ann Rheum Dis.2016 Oct;75(10):1858-65), non-alcoholic steatohepatitis (Garcia-Martinez et al. J Clin Invest 2016, 126: 859–864; Gabele et al. Biochem Biophys Res Commun.2008;376:271–276), hepatic injury (Shaker et al. Biochem Pharmacol.2016.112:90-101; Hoeque et al. J. Immun.2013, 190:4297-304), and scleroderma (systemic sclerosis or SSc) (Yoshizaki et al. Ann Rheum Dis .2016 Oct;75(10):1858-65); as well as heart failure (Oka et al. Nature 485, pages251– 255(2012)), and hypertension (McCarthy et al. Cardiovascular Research, 2015, Pages 119–130). There remains a need for compounds useful as inhibitors of TLR9. Additionally, there remains a need for compounds useful as inhibitors of TLR9 that have selectivity over TLR7 or TLR8. In view of the conditions that may benefit by treatment involving modulation of Toll-like receptors, it is immediately apparent that new compounds capable of inhibiting TLR9 and methods of using these compounds could provide substantial therapeutic benefits to a wide variety of patients. Applicants have found potent compounds that have activity as TLR9 inhibitors. Further, applicants have found compounds that have activity as TLR9 inhibitors and are selective over TLR7 or TLR8. These compounds are provided to be useful as pharmaceuticals with desirable stability, bioavailability, therapeutic index, and toxicity values that are important to their drugability.

Accordingly, the present invention further includes compositions comprising one or more compounds of Formula (I) and a pharmaceutically acceptable carrier. A "pharmaceutically acceptable carrier" refers to media generally accepted in the art for the delivery of biologically active agents to animals, in particular, mammals. Pharmaceutically acceptable carriers are formulated according to a number of factors well within the purview of those of ordinary skill in the art. These include without limitation the type and nature of the active agent being formulated; the subject to which the agent- containing composition is to be administered; the intended route of administration of the composition; and, the therapeutic indication being targeted. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid dosage forms. Such carriers can include a number of different ingredients and additives in addition to the active agent, such additional ingredients being included in the formulation for a variety of reasons, e.g., stabilization of the active agent, binders, etc., well known to those of ordinary skill in the art. Descriptions of suitable pharmaceutically acceptable carriers, and factors involved in their selection, are found in a variety of readily available sources such as, for example, Remington's Pharmaceutical Sciences, 17th Edition (1985), which is incorporated herein by reference in its entirety. Compounds in accordance with Formula (I) can be administered by any means suitable for the condition to be treated, which can depend on the need for site-specific treatment or quantity of Formula (I) compound to be delivered.

The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally acceptable diluent or solvent, for example as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer’s solution, 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 may be employed, including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables. A sterile injectable oil-in-water microemulsion can, for example, be prepared by 1) dissolving at least one compound of Formula (I) in an oily phase, such as, for example, a mixture of soybean oil and lecithin; 2) combining the Formula (I) containing oil phase with a water and glycerol mixture; and 3) processing the combination to form a microemulsion. A sterile aqueous or oleaginous suspension can be prepared in accordance with methods already known in the art. For example, a sterile aqueous solution or suspension can be prepared with a non-toxic parenterally-acceptable diluent or solvent, such as, for example, 1,3-butane diol; and a sterile oleaginous suspension can be prepared with a sterile non-toxic acceptable solvent or suspending medium, such as, for example, sterile fixed oils, e.g., synthetic mono- or diglycerides; and fatty acids, such as, for example, oleic acid. Pharmaceutically acceptable carriers, adjuvants, and vehicles that may be used in the pharmaceutical compositions of this invention include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, self-emulsifying drug delivery systems (SEDDS) such as d-alpha-tocopherol polyethyleneglycol 1000 succinate, surfactants used in pharmaceutical dosage forms such as Tweens, polyethoxylated castor oil such as CREMOPHOR surfactant (BASF), or other similar polymeric delivery matrices, serum proteins, such as human serum albumin, buffer substances such as phosphates, glycine, sorbic acid, potassium sorbate, partial glyceride mixtures of saturated vegetable fatty acids, water, salts or electrolytes, such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts, colloidal silica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethylcellulose, polyacrylates, waxes, polyethylene- polyoxypropylene-block polymers, polyethylene glycol and wool fat. Cyclodextrins such as alpha-, beta-, and gamma-cyclodextrin, or chemically modified derivatives such as hydroxyalkylcyclodextrins, including 2- and 3-hydroxypropyl-cyclodextrins, or other solubilized derivatives may also be advantageously used to enhance delivery of compounds of the formulae described herein. The pharmaceutically active compounds of this invention can be processed in accordance with conventional methods of pharmacy to produce medicinal agents for administration to patients, including humans and other mammals. The pharmaceutical compositions may be subjected to conventional pharmaceutical operations such as sterilization and/or may contain conventional adjuvants, such as preservatives, stabilizers, wetting agents, emulsifiers, buffers etc. Tablets and pills can additionally be prepared with enteric coatings. Such compositions may also comprise adjuvants, such as wetting, sweetening, flavoring, and perfuming agents. The amounts of compounds that are administered and the dosage regimen for treating a disease condition with the compounds and/or compositions of this invention depends on a variety of factors, including the age, weight, sex, the medical condition of the subject, the type of disease, the severity of the disease, the route and frequency of administration, and the particular compound employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. A daily dose of about 0.001 to 100 mg/kg body weight, preferably between about 0.0025 and about 50 mg/kg body weight and most preferably between about 0.005 to 10 mg/kg body weight, may be appropriate. The daily dose can be administered in one to four doses per day. Other dosing schedules include one dose per week and one dose per two day cycle. For therapeutic purposes, the active compounds of this invention are ordinarily combined with one or more adjuvants appropriate to the indicated route of administration. If administered orally, the compounds may be admixed with lactose, sucrose, starch powder, cellulose esters of alkanoic acids, cellulose alkyl esters, talc, stearic acid, magnesium stearate, magnesium oxide, sodium and calcium salts of phosphoric and sulfuric acids, gelatin, acacia gum, sodium alginate, polyvinylpyrrolidone, and/or polyvinyl alcohol, and then tableted or encapsulated for convenient administration. Such capsules or tablets may contain a controlled-release formulation as may be provided in a dispersion of active compound in hydroxypropylmethyl cellulose. Pharmaceutical compositions of this invention comprise at least one compound of Formula (I) and optionally an additional agent selected from any pharmaceutically acceptable carrier, adjuvant, and vehicle. Alternate compositions of this invention comprise a compound of the Formula (I) described herein, or a prodrug thereof, and a pharmaceutically acceptable carrier, adjuvant, or vehicle. The present invention also encompasses an article of manufacture. As used herein, article of manufacture is intended to include, but not be limited to, kits and packages. The article of manufacture of the present invention, comprises: (a) a first container; (b) a pharmaceutical composition located within the first container, wherein the composition, comprises: a first therapeutic agent, comprising: a compound of the present invention or a pharmaceutically acceptable salt form thereof; and, (c) a package insert stating that the pharmaceutical composition can be used for the treatment of a cardiovascular disorder, diuresis, and/or natriuresis. In another embodiment, the package insert states that the pharmaceutical composition can be used in combination (as defined previously) with a second therapeutic agent to treat cardiovascular disorder, diuresis, and/or natriuresis. The article of manufacture can further comprise: (d) a second container, wherein components (a) and (b) are located within the second container and component (c) is located within or outside of the second container. Located within the first and second containers means that the respective container holds the item within its boundaries. The first container is a receptacle used to hold a pharmaceutical composition. This container can be for manufacturing, storing, shipping, and/or individual/bulk selling. First container is intended to cover a bottle, jar, vial, flask, syringe, tube (e.g., for a cream preparation), or any other container used to manufacture, hold, store, or distribute a pharmaceutical product. The second container is one used to hold the first container and, optionally, the package insert. Examples of the second container include, but are not limited to, boxes (e.g., cardboard or plastic), crates, cartons, bags (e.g., paper or plastic bags), pouches, and sacks. The package insert can be physically attached to the outside of the first container via tape, glue, staple, or another method of attachment, or it can rest inside the second container without any physical means of attachment to the first container. Alternatively, the package insert is located on the outside of the second container. When located on the outside of the second container, it is preferable that the package insert is physically attached via tape, glue, staple, or another method of attachment. Alternatively, it can be adjacent to or touching the outside of the second container without being physically attached. The package insert is a label, tag, marker, or other written sheet that recites information relating to the pharmaceutical composition located within the first container. The information recited will usually be determined by the regulatory agency governing the area in which the article of manufacture is to be sold (e.g., the United States Food and Drug Administration). Preferably, the package insert specifically recites the indications for which the pharmaceutical composition has been approved. The package insert may be made of any material on which a person can read information contained therein or thereon. Preferably, the package insert is a printable material (e.g., paper, plastic, cardboard, foil, adhesive-backed paper or plastic) on which the desired information has been formed (e.g., printed or applied). METHODS OF PREPARATION The compounds of the present invention can be prepared in a number of ways well known to one skilled in the art of organic synthesis. The compounds of the present invention can be synthesized using the methods described below, together with synthetic methods known in the art of synthetic organic chemistry, or variations thereon as appreciated by those skilled in the art. Preferred methods include, but are not limited to, those described below. The reactions and techniques described in this section are performed in solvents appropriate to the reagents and materials employed and are suitable for the transformations being effected. Also, in the description of the synthetic methods described below, it is to be understood that all proposed reaction conditions, including choice of solvent, reaction atmosphere, reaction temperature, duration of the experiment and work up procedures, are chosen to be the conditions standard for that reaction, which should be readily recognized by one skilled in the art. It is understood by one skilled in the art of organic synthesis that the functionality present on various portions of the molecule must be compatible with the reagents and reactions proposed. Such restrictions to the substituents that are compatible with the reaction conditions will be readily apparent to one skilled in the art and alternate methods must then be used. This will sometimes require a judgment to modify the order of the synthetic steps or to select one particular process scheme over another in order to obtain a desired compound of the invention. It will also be recognized that another major consideration in the planning of any synthetic route in this field is the judicious choice of the protecting group used for protection of the reactive functional groups present in the compounds described in this invention. An authoritative account describing the many alternatives to the trained practitioner is Greene et al. (Protective Groups in Organic Synthesis, Fifth Edition, Wiley and Sons (2014)). Scheme 1 describes one potential route for the synthesis of compounds of Formula I-A and I-B, a subset of Formula I. The term “halo.” in this scheme refers to any halogen that one of ordinary skill in the art would deem proper to achieve the intended transformation. Compound 1a can be reacted with aldehyde 1b in the presence of sodium hydrosulfite, in a suitable solvent (e.g. EtOH, MeOH, DMSO, NMP), with heating, to furnish compound 1c. Contingent upon the nature of the R1 substituent, it may be necessary to first reduce the nitro group of compound 1a. Reduction is accomplished using a typical nitro-reducing agent (e.g. Fe powder, tin chloride dihydrate, catalytic hydrogenation), followed by cyclization with aldehyde 1b in the presence of sodium metabisulfite, in a suitable solvent (e.g. NMP, DMSO, EtOH), with heating to provide compound 1c. Compound 1c can be reacted with the appropriate boronate ester or boronic acid using standard Suzuki coupling conditions to furnish compounds of Formula I-A and I-B.

BIOLOGICAL ASSAYS The pharmacological properties of the compounds of this invention may be confirmed by a number of biological assays. The exemplified biological assays, which follow, have been carried out with compounds of the invention. TLR7/8/9 Inhibition Reporter Assays HEK-Blue™-cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors were used for screening inhibitors of these receptors using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of the IFN-β minimal promoter fused to five NF-κB and AP-1-binding sites. Cells are seeded into Greiner 384 well plates (15000 cells per well) that are pre dispensed (by ECHO) with testing compounds in DMSO to yield a final dose response concentration range of 0.85 nM-50 μM. After a 60 minute compound pre-treatment in 37 degree incubator, the cells are then stimulated with a TLR7 ligand (gardiquimod at a final concentration of 2.5 μM), TLR8 ligand (R848 at a final concentration of 14.25 μM) or TLR9 ligand (ODN2006 at a final concentration of 200 nM) to activate NF-κB and AP-1 which induce the production of SEAP. After a 22 hour incubation at 37 °C, 5% CO2, SEAP levels are determined with the addition of HEK-Blue™ Detection reagent (Invivogen), a cell culture medium that allows for detection of SEAP, according to manufacturer's specifications. The percent inhibition is determined as the % reduction in the HEK-Blue signal present in wells treated with agonist plus DMSO alone compared to wells treated with a known inhibitor.
