Abstract
Description
[Technical Field]
[0001] This application claims priority to U.S. Provisional Application No. 63 / 472,233, filed on 9 June 2023, the entire contents of which are incorporated herein by reference.
[0002] This application relates to the fields of chemistry and biology, and more particularly to compounds of formulas (I) and (II) as defined herein, as well as pharmaceutically acceptable salts thereof, and compositions comprising them. Furthermore, methods for treating diseases and disorders disclosed herein using compounds of formula (I) and / or formula (II), as well as pharmaceutically acceptable salts thereof, and compositions comprising them are also described. [Background technology]
[0003] Receptor-interacting protein kinase 2 (RIPK2) is a serine-threonine protein kinase and a downstream signaling molecule for nucleotide-binding oligomerized domain 1 (NODI), NOD2, and Toll-like receptors (TLRs). The RIPK2 protein contains a kinase domain (KD), an intermediate domain (INTD), and a caspase activation and recruitment domain (CARD). The CARD domain of RIPK2 mediates interactions with NODI and NOD2. RIPK2 is expressed in the cytoplasm of antigen-presenting cells, including dendritic cells and macrophages, and is also expressed in T cells and epithelial cells.
[0004] NOD receptors function in the innate immune system, detecting bacterial pathogens by binding to diaminopimelic acid or muramyl dipeptide residues present in bacterial peptidoglycans. Interactions between RIPK2 and NODI, NOD2, and TLRs induce the release of pro-inflammatory cytokines, including TNF-α, IL-6, and IL-12 / 23p40, as well as RIPK2-mediated induction of NF-κ-B-dependent inflammatory responses. RIPK2 activation and dysregulation of the RIPK2-NOD signaling pathway may also play a role in the pathogenesis of various inflammatory diseases. RIPK2 has been reported as a prognostic indicator and candidate therapeutic target for various cancers. [Overview of the project]

[0011] Other features and advantages of this disclosure will become apparent from the following detailed description and drawings, as well as from the claims. [Modes for carrying out the invention]
[0012] Biologics and small molecules targeting pro-inflammatory signaling pathways are used to successfully treat inflammatory and other diseases in patients; however, a significant portion of patients are refractory to existing therapies. Therefore, there is a need for the identification of novel therapeutic molecules that modulate or inhibit these pathways, such as compounds of formulas (I) and (II) described herein, and their pharmaceutically acceptable salts.
[0013] To facilitate understanding of the disclosures contained herein, some additional terms are defined below. In general, the nomenclature used herein, as well as the experimental procedures in organic chemistry, medicinal chemistry, and pharmacology described herein, are well known and commonly used in the art. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this disclosure belongs. Each of the patents, applications, published applications, and other publications referenced throughout this specification and its accompanying appendices is incorporated herein by reference in their entirety.

[0015] The term "therapeutic dose" means an amount of the compound that, when administered to a subject requiring such treatment, is sufficient to (i) treat a disease or disorder described herein (e.g., RIPK2-related disease or disorder), (ii) reduce, improve or eliminate one or more symptoms of a particular disease or disorder, or (iii) delay the onset of one or more symptoms of a particular disease or disorder described herein.
[0016] As used herein, the terms “to treat” or “treatment” refer to therapeutic or symptomatic measures. Beneficial or desired clinical outcomes include, but are not limited to, general or partial relief of symptoms associated with the disease or disorder, reduction in the degree of neurological impairment, stabilization (i.e., non-exacerbating) of the disease or disorder, delay or slowing of disease progression, improvement or relief of the disease state (e.g., one or more symptoms of the disease or disorder), and remission (whether partial or general), which can be determined by various clinical assessments, including clinical evaluations and self-reports, whether detectable or undetectable. “Treatment” may also mean an extension of survival compared to expected survival without treatment.
[0017] The term “pharmaceutically acceptable excipient” means a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, carrier, solvent, or encapsulating material.

[0037] [ka] ), pyrimidone (for example,
[0038] [ka] ), pyridazinon (for example,
[0039] [ka] ), pyrazinon (for example,
[0040] [ka] ), and imidazolone (for example,
[0041] [ka] ) where each ring nitrogen adjacent to the carbonyl is tertiary (i.e., the oxo group (i.e., "=O") in this specification is a component of a heteroaryl ring).
[0042] As used herein, the term "cycloalkyl" refers to a saturated or partially unsaturated monocyclic, bicyclic, or tricyclic carbon group having 3 to 20 carbon atoms. Bicyclic and tricyclic cycloalkyl groups include fused ring systems, spiro ring systems, and crosslinking ring systems.

[0044] The term "aryl" refers to a 6- to 20-carbon monocyclic, bicyclic, tricyclic, or polycyclic group in which at least one ring in the system is aromatic (e.g., a 6-carbon monocyclic, 10-carbon bicyclic, or 14-carbon tricyclic aromatic ring system). Examples of aryl groups include phenyl, naphthyl, and tetrahydronaphthyl.
[0045] The term “heterocyclyl” refers to a saturated or partially unsaturated hydrocarbon monocyclic, bicyclic, or tricyclic ring system having 3 to 20 ring atoms, not being aromatic, and containing at least one heteroatom within a ring system selected from the group consisting of N, O, S, B, Si, and P. Bicyclic and tricyclic heterocycloalkyl groups include fused ring systems, spirocyclic systems, and bridging ring systems. A heterocyclyl group may also be expressed as a “5- to 10-membered heterocyclyl group,” which is a ring system containing 5, 6, 7, 8, 9, or 10 atoms, with at least one being a heteroatom. A heterocycle may further contain one or more valence-acceptable oxo, thiocarbonyl, N-oxide, S-oxide, and / or S,S-dioxide groups so that its definition includes oxo and thio systems, e.g., lactams, lactones, cyclic imides, cyclic thioimides, and cyclic carbamates.

[0046] In this context, the term "saturated" refers only to single bonds present between constituent atoms.
[0047] As used herein, when a ring is described as “partially unsaturated,” this means that, provided the ring is not aromatic, the ring has one or more additional degrees of unsaturation (in addition to the degree of unsaturation attributable to the ring itself, for example, one or more double or triple bonds between the constituent ring atoms). Examples of such rings include cyclopentene, cyclohexene, cycloheptene, dihydropyridine, tetrahydropyridine, dihydropyrrole, dihydrofuran, and dihydrothiophene.
[0048] Where used herein, the symbol
[0049] [ka] This indicates the bonding point of the atom or part to the indicated atom or group in the rest of the molecule.
[0050] Whenever a group is described as "optionally substituted," that group may be unsubstituted or substituted with one or more of the substituents shown. If the group is substituted, the substitution may involve sharing a carbon atom between the parent group and the substitution in order to form a spiro ring. For example, a cyclopropyl-substituted n-butyl group, among other things,
[0051] [ka] Includes.
[0052] To avoid misunderstanding, unless otherwise specified, for rings and cyclic groups (e.g., carbocyclic, aryl, cycloalkyl, heterocyclyl, heteroaryl, etc. as described herein) that contain a sufficient number of ring atoms to form a bicyclic or higher-order cyclic system (e.g., tricyclic, polycyclic cyclic systems), such rings and cyclic groups have condensation points where (i) adjacent ring atoms (e.g., [xx0] ring systems, where 0 is zero-atom bridges (e.g.,
[0053] [ka] (ii) Represents) (ii) Monocyclic atom (spiro-condensed ring system) (for example,
[0054] [ka] ), or (iii) a continuous array of ring atoms (a bridged ring system in which all bridge lengths are greater than 0 (>0)) (for example,
[0055] [ka] It is understood that this includes those having a fused ring, including those located on the ) surface.
[0056] In addition, any compound or structure described herein is intended to represent both an unlabeled and an isotope-labeled form of the compound. Compounds in these forms are referred to as “isotope-enriched.” An isotope-enriched compound has the structure described herein, except that one or more atoms are substituted with atoms having a selected atomic mass or mass number.
[0057] Examples of isotopes that can be incorporated into the disclosed compounds include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorus, fluorine, chlorine, and iodine, for example, respectively. 2 H, 13 C, 14 C, 13 N, 15 N, 15 O, 17 O, 18 O, 31 P, 32 P, 35 S, 18 F, 36 C1, 123 I, and 125 I is an example. Various isotope-enriched compounds of this disclosure, for example, 13 C and 14Compounds incorporating radioactive isotopes such as 13C. Such isotope-enriched compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays, or in radiotherapy for patients.
[0058] The term “isotope-enriched” compounds include “deuterated” compounds as described herein, in which one or more hydrogens are substituted with deuterium, such as hydrogen on a carbon atom. Such compounds exhibit increased resistance to metabolism and are therefore useful for increasing the half-life of any compound when administered to mammals, particularly humans. Such compounds are synthesized by means known in the art, for example, by using starting materials in which one or more hydrogens are substituted with deuterium. In fact, the isotope-enriched compounds of this disclosure can generally be prepared by performing the procedures disclosed in the scheme or in the examples and preparations below, by using readily available isotope-enriched reagents instead of non-isotope-enriching reagents.
[0059] The deuterium-enriched compounds of this disclosure may have improved DMPK (drug metabolism and pharmacokinetic) properties with respect to distribution, metabolism, and excretion (ADME). Substitution with heavier isotopes such as deuterium may result in certain therapeutic advantages, such as increased in vivo half-life, reduced dosage requirements, and / or improved therapeutic index, compared to the corresponding non-enriched compounds, due to greater metabolic stability.
[0060] The concentration of heavier isotopes, such as deuterium, can be defined by isotopic enrichment factors. In some embodiments, the positions described as "H" or "hydrogen" in the compounds described herein have hydrogen at their naturally occurring isotopic composition. In some embodiments, the positions described as "H" or "hydrogen" in the compounds described herein have hydrogen enriched with deuterium beyond its naturally occurring isotopic composition; i.e., the compounds are deuterium-enriched compounds. Examples of deurated groups in the compounds described herein, but not limited to, deuterated methine (
[0061] [ka] ), monodeuterated methylene (
[0062] [ka] ) and dideuterated methylene (
[0063] [ka] ), methyl trideuterated (
[0064] [ka] ), trideuterated methoxy(
[0065] [ka] ) are some examples.
[0066] Furthermore, the compounds disclosed comprehensively or specifically herein are intended to include all tautomer forms. Therefore, as an example, the following parts...
[0067] [ka] Compounds containing the following parts
[0068] [ka] This includes tautomer forms containing [the specified compound]. Similarly, pyridinyl or pyrimidinyl moieties described as being optionally substituted with hydroxyl include pyridone or pyrimidone tautomer forms.
[0069] The compounds provided herein may encompass a variety of stereochemical forms. The compounds further include enantiomers (e.g., R and S isomers), diastereomers, and mixtures of enantiomers (e.g., R and S isomers), including racemic mixtures and mixtures of diastereomers, as well as individual enantiomers and diastereomers resulting from structural asymmetry in particular compounds. Unless otherwise indicated, if a disclosed compound is named or indicated by a structure (e.g., a "flat" structure) without specifying its stereochemistry and has one or more chiral centers, it is understood to represent all possible stereoisomers of the compound. Similarly, unless otherwise indicated, if a disclosed compound is named or indicated by a structure that specifies its stereochemistry (e.g., a structure with "wedge" and / or "wavy" bonds) and has one or more chiral centers, it is understood to represent a specified stereoisomer of the compound.
[0070] Details of one or more embodiments of this disclosure are described in the accompanying drawings and the following description. Other features and advantages of this disclosure will become apparent from the detailed description and the claims.
[0071] The term "RIPK2 inhibitor" as defined herein includes any compound exhibiting RIPK2 inhibitory activity. In some embodiments, RIPK2 inhibitors are selective for RIPK2. Exemplary RIPK2 inhibitors, when measured in the assay described herein, exhibit inhibitory activity (IC) against RIPK2 of less than about 1000 nM, less than about 500 nM, less than about 200 nM, less than about 100 nM, less than about 50 nM, less than about 25 nM, less than about 10 nM, less than about 5 nM, or less than about 1 nM. 50 ) can be shown. In some embodiments, RIPK2 inhibitors, when measured in the assay provided herein, exhibit inhibitory activity (IC) against RIPK2 less than about 25 nM, less than about 10 nM, less than about 5 nM, or less than about 1 nM. 50 ) can be shown.
[0072] Compounds of formula (I) and formula (II) RIPK2 mediates inflammatory signaling via NODI, NOD2, and TLRs. However, in vitro inhibition of RIPK2 kinase activity alone does not fully predict the suppression of downstream cellular RIPK2 signaling. Rather, interfering with the interaction between RIPK2 and XIAP is necessary to potently reduce inflammatory signaling. In some cases, potent inhibitors of RIPK2 kinase activity lack the ability to disrupt RIPK2 / XIAP binding and therefore lack the ability to completely block inflammatory signaling in cells or human subjects. This disclosure is in part based on the discovery that selected compounds described herein exert RIPK2 inhibition by co-inhibiting RIPK2 kinase activity and disrupting the RIPK2 / XIAP interaction, thereby reducing cellular inflammatory signaling.
[0073] Some embodiments use formula (I) or formula (II)

[0543] Biological data RIPK2 binding competition assay The ability of selected compounds of formulas (I) and (II) to inhibit the binding of Alexa647-labeled ATP competitive kinase inhibitors to the GST-RIPK2 fusion protein was quantified using the TR-FRET-based RIPK2 binding competition assay described in the following paragraphs.
[0544] A recombinant fusion protein of N-terminal glutathione-S-transferase (GST) expressed in baculovirus-infected Sf9 cells, purified via glutathione affinity chromatography, and a fragment of human RIPK2 (amino acids 1-310 of accession number O43353) was used as the GST-RIPK2 fusion protein. Life Technologies' Tracer199 (catalog number PR9115B) was used as the Alexa647-labeled ATP competitive kinase inhibitor.
[0545] For the assay, 50 nL of a 100-fold concentrated solution of each test compound in DMSO was pipetteed into either a black low-volume 384-well microtiter plate or a black 1536-well microtiter plate (both Greiner Bio-One, Flickenhausen, Germany). The assay buffer consisted of: 25 mM Tris / HCl pH 7.5, 10 mM magnesium chloride (MgCl2), 5 mM β-glycerophosphate, 2.5 mM dithiothreitol (DTT), 0.5 mM ethylene glycol-bis(2-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA), 0.5 mM sodium ortho-vanadate, 0.01% (w / v) bovine serum albumin (BSA), and 0.005% (w / v) Pluronic acid. A 3 μL solution of Tracer199 (16.7 nM ⇒ final concentration of 10 nM in a 5 μL assay volume) was added to F-127 (Sigma). Subsequently, binding competition was initiated by adding a 2 μL solution of GST-RIPK2 fusion protein (2.5 nM ⇒ final concentration of 1 nM in a 5 μL assay volume) and anti-GST-Tb (1.25 nM ⇒ final concentration of 0.5 nM in a 5 μL assay volume) in the assay buffer, along with PerkinElmer's Lumi4®-Tb cryptotate conjugate anti-GST antibody (catalog number 61GSTTAH). The resulting mixture was incubated at 22°C for 45 minutes to allow a complex to form between Tracer199, the fusion protein, and anti-GST-Tb. The amount of this complex was then assessed by measuring the resonance energy transfer from Tb cryptotate to Tracer199. Therefore, fluorescence intensities at 620 nm and 665 nm after excitation at 337 nm were measured using a TR-FRET reader, e.g., Pherastar FS (BMG Labtechnologies, Offenburg, Germany) or Viewlux (PerkinElmer). The ratio of fluorescence intensities at 665 nm to 620 nm was used as an indicator of the complex's volume. Data were normalized (assay reaction without inhibitor = 0% activity, all other assay components excluding the GST-RIPK2 fusion protein = -100% activity). Typically, the test compound is tested on the same microtiter plate at 11 different concentrations ranging from 20 μM to 0.07 nM (20 μM, 5.7 μM, 1.6 μM, 0.47 μM, 0.13 μM, 38 nM, 11 nM, 3.1 nM, 0.9 nM, 0.25 nM, and 0.07 nM. This dilution series was prepared separately before the assay by serial dilution at the 100-fold concentrated stage in DMSO, and the exact concentration may vary depending on the pipette used), with two consecutive values for each concentration, and IC using Geneda Screener® software. 50 The value was calculated. Table A1 below shows the IC25 of selected compounds of formula (I) measured in the RIPK2 binding competition assay. 50 The values are shown. IC of the RIPK2 competitive assay. 50 Regarding the values, "A" represents ICs with a minimum impedance of 200 nM. 50 This indicates that "B" represents an IC with a impedance of 200nM to 500nM. 50 This indicates that "C" represents ICs with a impedance of over 500nM and less than or equal to 1,000nM. 50 This indicates that "D" represents an IC with a power output exceeding 1,000 nM. 50 This indicates.

[0547] RIPK2-XIAP Competitive PPI Assay The ability of selected compounds of formula (I) to inhibit the binding of the His-XIAP(BIR2)-avi fusion protein to the GST-RIPK2 fusion protein was quantified using the TR-FRET-based competitive assay described in the following paragraphs.
[0548] A recombinant fusion protein of N-terminal glutathione-S-transferase (GST) expressed in baculovirus-infected Sf9 cells, purified via glutathione affinity chromatography, and a fragment of human RIPK2 (amino acids 1-310 of accession number O43353) was used as the GST-RIPK2 fusion protein. A recombinant fusion protein of N-terminal 6x histidine (His), a fragment of human XIAP (amino acids 152-231 of accession number P98170), and a C-terminal avi tag, purified via nickel NTA affinity chromatography, expressed in baculovirus-infected Sf9 cells, was used as the His-XIAP(BIR2)-avi fusion protein.
[0549] For the assay, use 25 mM Tris-HCl 7.5, 0.5 mM ethylene glycol-bis(2-aminoethyl ether)-N,N,N',N'-tetraacetic acid (EGTA), 10 mM magnesium chloride (MgCl2), 2.5 mM dithiothreitol (DTT), 0.01% (w / v) bovine serum albumin (BSA), and 0.005% (w / v) Pluronic acid. Working solutions were prepared using F-127 (Sigma), 0.5 mM sodium ortho-vanadate, 5 mM disodium β-glycerophosphate hydrate (BGP) containing 1 nM GST-RIPK2, 25 nM His-XIAP(BIR2)-avi, 6 nM anti-His-XL665 (Revvity, catalog no. 61HISXLB), and 0.5 nM anti-GST-Tb (Revvity, catalog no. 61GSTTLB). 50 nL of a 100-fold concentrated solution of each test compound in DMSO was dispensed acoustically into a white, low-volume 384-well microtiter plate (Perkin Elmer, catalog no. 6008280). Subsequently, 5 μl of the assay working solution was added.
[0550] The resulting mixture was incubated at 23°C for 120 minutes. Subsequently, the amount of complex formed by GST-RIPK2, XIAP(BIR2)-avi, anti-His-XL665, and anti-GST-Tb was assessed by measuring the resonance energy transfer from Tb cryptotate to XL665. Therefore, using a TR-FRET reader, e.g., Pherastar FS (BMG Labtechnologies, Offenburg, Germany) or Envision (PerkinElmer), fluorescence intensities at 520 nm and 665 nm after excitation at 337 nm were measured. The ratio of fluorescence intensities at 665 nm to 520 nm was used as an indicator of the complex amount. Data were normalized (assay reaction without inhibitor = 0% activity, 50 nM GSK583 = -100% activity). Typically, the test compound is tested on the same microtiter plate at 11 different concentrations ranging from 10 μM to 0.04 nM (10 μM, 2.86 μM, 0.82 μM, 0.23 μM, 67 nM, 19 nM, 5.4 nM, 1.6 nM, 0.4 nM, 0.1 nM, and 0.04 nM. This dilution series was prepared separately before the assay by serial dilution in 100-fold concentrated DMSO solutions, and the exact concentration may vary depending on the pipette used), with two consecutive values for each concentration, and ICs are performed using Collaborative Drug Discovery software. 50 The value was calculated.
[0551] SEAP and viability assay of THP-1 Dual cells THP1-Dual® cells (InvivoGen catalog number thpd-nfis) enable simultaneous evaluation of the NF-κB pathway by monitoring the activity of secretory embryonic alkaline phosphatase (SEAP) and the IRF pathway by assessing the activity of secretory luciferase (Lucia). Cells were cultured according to the manufacturer's recommendations. For the assay, cell concentrations were set to 7.14 × 10⁴ in assay medium (RPMI1640, 2 mM L-glutamine, 25 mM HEPES, 10% fetal bovine serum (thermally inactivated at 56°C for 30 minutes), Pen-Strep (100 U / mL)). 5The cell suspension was adjusted to cells / mL, and 35 μL per well (approximately 25,000 cells) was added to a flat-bottomed 384-well plate (white opaque). The plate was centrifuged at 300 g for 2 minutes, and the compound was added in a serial dilution series (approximately 500 nL to 0.0152 nL) according to the plate layout. The plate was incubated at 37°C under 5% CO2 conditions for 30 minutes. Using assay medium, an L18-MDP stock solution was prepared so that the final concentration of L18-MDP in each well was 10 ng / mL when 15 μL was added to each well. 15 μL of the L18-MDP stock solution was added to each well, while 15 μL of assay medium was added to the negative control well. The plate was then incubated overnight (20-24 hours) at 37°C under 5% CO2 conditions.
[0552] SEAP assay: To avoid disturbing the cells at the bottom of the wells, 15 μL of supernatant was transferred to a clear 384-well flat-bottom plate, and 35 μL of QUANTI-Blue solution was added per well. After incubation at 37°C for 2 hours, absorbance (OD) at 620–655 nm was measured using a microplate reader (PheraStar FS microplate reader with a protocol for OD 620–655 nm).
[0553] Cell viability assay: Cell viability was evaluated using cells remaining in the plate. For this purpose, CellTiter-Glo buffer and lyophilized CellTiter-Glo substrate were equilibrated at room temperature, and the lyophilized CellTiter-Glo substrate was reconstituted according to the manufacturer's recommendations. Equivolutes (35 μL in this case) of CTG were added to each well, and the contents were mixed in an orbital shaker for 2 minutes to induce lysis, followed by incubation at room temperature for 10 minutes. Subsequently, the luminescence signal was measured using a microplate reader (PheraStar).
[0554] analysis The values from the wells containing only the culture medium were subtracted, and the inhibition rate (%) at each compound concentration was calculated relative to the control treated with DMSO / L18-MDP. The inhibition values ± SD were fitted using nonlinear regression with Prism software (GraphPad PRISM Software), and IC was calculated. 50 The value was calculated.
