Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This application claims the benefit of U.S. Provisional Application No. 62 / 749,828, filed October 24, 2018, the entire contents of which are incorporated herein by reference.

[0002] Description of the Invention The present invention relates generally to substituted indole and indazole compounds useful as inhibitors of signaling through Toll-like receptors 7, 8, or 9 (TLR7, TLR8, TLR9), or combinations thereof. Provided herein are substituted indole compounds, compositions comprising such compounds, and methods of their use. The invention further relates to pharmaceutical compositions containing at least one compound according to the invention that are useful in the treatment of conditions associated with TLR modulation, such as inflammation and autoimmune diseases, as well as methods of inhibiting the activity of TLRs in a mammal. [Background technology]

[0003] Toll / IL-1 receptor family members are important regulators of inflammation and host resistance. The Toll-like receptor family recognizes molecular patterns derived from infectious microorganisms, including bacteria, fungi, parasites, and viruses (reviewed in Kawai, T. et al., Nature Immunol., 11: 373-384 (2010)). Ligands bind to the receptors, except for TLR3, and induce dimerization and recruitment of adapter molecules to a conserved cytoplasmic motif in the receptor called the Toll / IL-1 receptor (TIR) ​​domain. All TLRs recruit the adapter molecule MyD88. The IL-1 receptor family also contains a cytoplasmic TIR motif and recruits MyD88 upon ligand binding (reviewed in Sims, JE et al., Nature Rev. Immunol., 10: 89-102 (2010)).

[0004] Toll-like receptors (TLRs) are a series of evolutionarily conserved transmembrane innate immune receptors involved in the first line of defense. As pattern recognition receptors, TLRs prevent foreign molecules from damaged tissues that are activated by pathogen-associated molecular patterns (PAMPs) or danger-associated molecular patterns (DAMPs). A total of 13 TLR family members, of which 10 in humans, have been identified, spanning either the cell surface or endosomal compartments. TLR7 / 8 / 9 is one of a set that is located in endosomes and responds to single-stranded RNA (TLR7 and TLR8) or unmethylated single-stranded DNA containing cytosine-phosphate-guanine (CpG) motifs (TLR9).

[0005] Activation of TLR7 / 8 / 9 can initiate various inflammatory responses (cytokine production, B cell activation and IgG production, type I interferon response). In the case of autoimmune disorders, abnormal persistent activation of TLR7 / 8 / 9 leads to exacerbation of the pathology. Overexpression of TLR7 in mice was shown to exacerbate autoimmune disease, whereas knockout of TLR7 mice was found to be protective against disease in lupus-prone MRL / lpr mice. Dual knockout of TLR7 and 9 showed further enhanced protection.

[0006] Since many conditions may benefit from treatments involving modulation of cytokines, IFN production and B cell activation, it is readily apparent that novel compounds capable of modulating TLR7 and / or TLR8 and / or TLR9, and methods employing these compounds, may provide substantial therapeutic benefit to a wide variety of patients.

[0007] The present invention relates to a series of novel indole and indazole compounds that have been found to be effective inhibitors of signaling through TLR7 / 8 / 9. These compounds are provided to be useful as pharmaceuticals with desirable stability, bioavailability, therapeutic index and toxicity values ​​that are important for their druggability.

The term "solvate" refers to a physical association of a compound of formula (I) with one or more solvent molecules, whether organic or inorganic. The physical association includes hydrogen bonding. In some cases, such as when one or more solvent molecules are incorporated into the crystal lattice of a crystalline solid, the solvate will be capable of isolation. "Solvates" consist of both solution-phase and separable solvates. Exemplary solvates include hydrates, ethanolates, methanolates, isopropanolates, acetonitrile solvates, and ethyl acetate solvates. Methods of solvation are known in the art.

[0055] Various forms of prodrugs are well known in the art and are described in the following references: a)The Practice of Medicinal Chemistry, Camille G.

[0061] usefulness The human immune system has evolved to defend the body against microbes, viruses and parasites that can cause infection, disease or death. Complex regulatory mechanisms ensure that the various cellular components of the immune system target foreign substances or organisms while not causing permanent or significant damage to the individual. Although the initiating events are not fully understood at present, in autoimmune pathologies, the immune system directs its inflammatory response to target organs in the affected individual. Various autoimmune diseases are typically characterized by the predominant or initial target organ or tissue affected by the disease, such as the joints in the case of rheumatoid arthritis, the thyroid gland in the case of Hashimoto's thyroiditis, the central nervous system in the case of multiple sclerosis, the pancreas in the case of type I diabetes, and the intestine in the case of inflammatory bowel disease.

[0062] The compounds of the present invention inhibit signaling through Toll-like receptors 7, 8, or 9 (TLR7, TLR8, TLR9) or combinations thereof. Thus, the compounds of formula (I) have utility in treating conditions involving inhibition of signaling through one or more of TLR7, TLR8, or TLR9. Such conditions include TLR7, TLR8, or TLR9 receptor-associated diseases in which cytokine levels are regulated as a result of intracellular signaling.

[0072] The compositions of the invention may contain other therapeutic agents as described above and may be formulated according to methods such as techniques well known in the art of pharmaceutical formulation, for example, by utilizing conventional solid or liquid vehicles or diluents, as well as pharmaceutical additives (e.g., excipients, binders, preservatives, stabilizers, flavorings, etc.) of a type appropriate for the desired mode of administration. Accordingly, the present invention further includes compositions comprising one or more compounds of formula (I) and a pharma- ceutically acceptable carrier.

[0073] "Pharmaceutically acceptable carrier" refers to a medium generally accepted in the art for delivering biologically active agents to animals, particularly mammals. Pharmaceutically acceptable carriers are formulated according to a number of factors well within the scope of the skilled artisan's concerns. These include, but are not limited to, the type and characteristics of the active agent being formulated; the subject to which the composition containing the active agent is to be administered; the intended route of administration of the composition; and the targeted therapeutic indication. Pharmaceutically acceptable carriers include both aqueous and non-aqueous liquid media, as well as a variety of solid and semi-solid forms. Such carriers can include many different components and additives in addition to the active agent, and such additional components are included in the formulation for a variety of reasons well known to those skilled in the art, such as stabilization of the active agent, binders, etc. Descriptions of suitable pharmacopoeia acceptable carriers and the factors involved in their selection can be found in many readily available sources, such as, for example, Remington's Pharmaceutical Sciences, 17th Edition (1985), the contents of which are incorporated herein by reference.

Examples of the second container include, but are not limited to, boxes (e.g., cardboard or plastic), crates, bins, bags (e.g., paper or plastic bags), sachets, and sacks. The package insert can be physically attached to the outside of the first container via tape, adhesive, staples, or another adhesive method, or can be placed inside the second container without any physical means of attachment to the first container. Alternatively, the package insert can be placed outside the second container. When placed outside the second container, the package insert is preferably physically attached via tape, adhesive, staples, or another adhesive method. Alternatively, the package insert can be adjacent to or in contact with the outside of the second container without being physically attached.

[0097] The package insert is a label, tag, marker, etc., that describes information about the pharmaceutical composition contained in the first container. The information described will usually be determined by the regulatory agency (e.g., the U.S. Food and Drug Administration) that governs the region in which the product is sold. In one embodiment, the package insert specifically describes the indication for which the pharmaceutical composition is approved. The package insert may be made of any material that allows a person to read the information contained therein or thereon. For example, the package insert is a printable material (e.g., paper, plastic, cardboard, foil, adhesive-backed paper or plastic, etc.) on which the desired information is formed (e.g., printed or coated).

[0098] Manufacturing method The compounds of the present invention can be prepared in many ways well known to those 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 with variations thereon as recognized by those skilled in the art. Preferred methods include, but are not limited to, the methods described below. All references cited herein are incorporated herein by reference.

[0099] The compounds of the present invention can be prepared using the reactions and methods described in this section. The reactions are carried out in solvents suitable for the reagents and materials employed, and the reactions are suitable for transformation. It should also be understood that in the following description of the synthetic methods, all reaction conditions proposed, including the choice of solvent, reaction environment, reaction temperature, duration of the experiment, and work-up procedures, are selected to be standard conditions for the reaction, which would be readily recognized by one skilled in the art. Those skilled in the art of organic synthesis will understand that the functional groups on the various parts of the molecule must be compatible with the proposed reagents and reactions. Such restrictions on the substituents compatible with the reaction conditions will be apparent to those skilled in the art, and alternative methods will then need to be used. This will sometimes require judgment to modify the order of synthetic steps or to select one particular process scheme over another to obtain the desired compound of the present invention. It should also be understood that another major factor in planning a synthetic route in this field is the correct selection of the protecting groups used to protect the functional groups present in the compounds described in the present invention. An authoritative manual teaching many of these modifications to one of skill in the art is Greene and Wuts (Protective Groups in Organic Synthesis, 3rd ed., Wiley and Sons, 1999).

[0228] Biological assays The pharmacological properties of the compounds of the invention can be confirmed in a number of biological assays. The following representative biological assays have been carried out with the compounds of the invention.

[0229] TLR7 / 8 / 9 Inhibitory Receptor Assay HEK-Blue® cells (Invivogen) overexpressing human TLR7, TLR8 or TLR9 receptors, using an inducible SEAP (secreted embryonic alkaline phosphatase) reporter gene under the control of an IFN-β minimal promoter fusion with five NF-κB and AP-1-binding sites, were used to screen inhibitors of these receptors. Briefly, cells were seeded in Greiner 384-well plates (15,000 cells / well for TLR7, 20,000 cells / well for TLR8, and 25,000 cells / well for TLR9) and then treated with test compounds in DMSO to give final dose response concentrations ranging from 0.05 nM to 50 μM. After 30 minutes of pretreatment with compounds at room temperature, the cells are then stimulated with TLR7 ligand (gardiquimod at 7.5 μM final concentration), TLR8 ligand (R848 at 15.9 μM final concentration), or TLR9 ligand (ODN2006 at 5 nM final concentration) to activate NF-κB and AP-1, thereby inducing the production of SEAP. After 22 hours of incubation at 37° C. and 5% CO2, SEAP levels are measured by adding HEK-Blue® detection reagent (Invivogen), cell culture medium, which allows the detection of SEAP, according to the manufacturer's specifications. % inhibition is measured as the % reduction in HEK-Blue signal present in wells treated with agonist and DMSO alone compared to wells treated with known inhibitors.
