Description

[Technical field]

[0001] Field of Disclosure The present disclosure relates to compounds that modulate receptor interacting protein 1 (RIP1), compositions comprising the compounds, methods of preparing the compounds, and methods of using the compounds to treat various diseases or conditions, e.g., mediated by RIP1. [Background technology]

[0002] Background of the disclosure Necroptosis, an important form of programmed cell death (PCD), is a highly regulated, caspase-independent form of cell death that plays a key role in many necrotic cell diseases, including ischemic brain injury, neurodegenerative diseases, viral infections, and peripheral autoimmune diseases (Dunai, et al., Dec 2011, Pathol. Oncol. Res.: POR 17 (4): 791-800. J. Med. Chem. 2020, 63, 4, 1490-1510. Nature Reviews Drug Discovery, 19, 553-571(2020)). Tumor necrosis factor alpha (TNF-α)-induced NF-κB activation plays a central role in the immune system and inflammatory responses.

[0003] Receptor interacting protein 1 (RIP1) is a multifunctional signal transduction agent involved in the activation of nuclear factor kappa B (NF-kappa B), apoptosis, and mediation of necroptosis. The kinase activity of RIP1 plays a key role in mediating necroptosis, a caspase-independent necrotic cell death pathway (Holler et al. Nat Immunol 2000; 1: 489-495; Degterev et al. Nat Chem Biol 2008; 4: 313-321). RIP1 is involved in D-1 immunotherapy resistance (e.g., Manguso et al., 2017 Nature 547, 413-418) and may function as a checkpoint kinase to control tumor immunity (e.g., Wang et al, Cancer Cell 34, 757-774, Nov 12, 2018). RIP1 has emerged as a promising therapeutic target for the treatment of a wide range of human neurodegenerative, autoimmune, and inflammatory diseases, such as psoriasis, rheumatoid arthritis, and ulcerative colitis (Pharmacol. Res. Perspect. 2017, 5, e00365, PNAS May 14, 2019 116 (20) 9714-9722), as well as CNS indications such as ALS and Alzheimer's disease (Nat. Rev. Neurosci. 2019, 20, 19-33).

"Heterocycle" also refers to a 5-7 membered heterocycle containing at least one heteroatom selected from N, O and S fused to a 5-, 6- and / or 7-membered cycloalkyl, carbocyclic or heterocyclic aromatic ring, where the point of attachment is on the heterocycle when the heterocycle is fused to a carbocyclic or heterocyclic aromatic ring, and where the point of attachment is on either the cycloalkyl or heterocycle when the heterocycle is fused to a cycloalkyl.

[0021] "Heterocycle" also refers to an aliphatic spirocycle containing at least one heteroatom selected from N, O, and S, where the point of attachment is at the heterocycle. These rings may be saturated or have at least one double bond (i.e., partially unsaturated). The heterocycle may be substituted with oxo.

[0023] The term "fused ring" as used herein refers to a polycyclic ring system (e.g., a bicyclic or tricyclic ring system) in which two rings share only two ring atoms and one bond. Examples of fused rings include fused bicyclic cycloalkyl rings, such as those having 7-12 ring atoms arranged as a bicyclic group selected from the [4,4] ring system, [4,5] ring system, [5,5] ring system, [5,6] ring system, and [6,6] ring system described above; fused bicyclic aryl rings, such as the 7-12 membered bicyclic aryl ring system described above; fused tricyclic aryl rings, such as the 10-15 membered tricyclic aryl ring system described above; fused bicyclic heteroaryl rings, such as the 8-12 membered bicyclic heteroaryl ring described above; fused tricyclic heteroaryl rings, such as the 11-14 membered tricyclic heteroaryl ring described above; and fused bicyclic or tricyclic heterocyclyl rings described above.

[0024] The term "heteroatom" refers to any oxidized form of nitrogen or sulfur; the quaternized form of any basic nitrogen or a substitutable nitrogen of a heterocyclic ring, such as N (as in 3,4-dihydro-2H-pyrrolyl), NH (as in pyrrolidinyl) or NR + "N" means one or more of oxygen, sulfur, nitrogen, or phosphorus (including, as in the case of N-substituted pyrrolidinyl). The term "unsaturated," as used herein, means that a moiety has one or more units or degrees of unsaturation. Unsaturation is a situation in which not all of the available valence bonds in a compound are saturated with substituents, such that the compound contains one or more double or triple bonds.

[0025] The term "alkoxy," as used herein, refers to an alkyl group, as defined above, wherein one carbon of the alkyl group is replaced by an oxygen atom, provided that the oxygen atom is linked between two carbon atoms. The term "halogen" includes F, Cl, Br, and I, i.e., fluoro, chloro, bromo, and iodo, respectively.

[0026] As used herein, a "cyano" or "nitrile" group refers to --C.ident.N. As used herein, "aromatic ring" refers to a bonded, planar ring system having a delocalized π orbital consisting of [4n+2]p orbital electrons, where n is an integer from 0 to 6. "Nonaromatic" rings refer to carbocyclic or heterocyclic rings that do not meet the conditions set forth above for aromatic rings and may be fully or partially saturated. Non-limiting examples of aromatic rings include aryl and heteroaryl rings, further defined as follows:

[0027] The term "aryl," as used herein, refers to groups selected from 5- and 6-membered carbocyclic aromatic rings (such as phenyl); bicyclic systems (such as 7-12 membered bicyclic systems) in which at least one ring is carbocyclic aromatic (such as bicyclic systems selected from naphthalene, indane, and 1,2,3,4-tetrahydroquinoline); and tricyclic systems (such as 10-15 membered tricyclic systems) in which at least one ring is carbocyclic aromatic (such as fluorene).

[0028] For example, the aryl group is selected from 5- and 6-membered carbocyclic aromatic rings fused to a 5- to 7-membered cycloalkyl ring or heterocycle, which may contain at least one heteroatom selected from N, O, and S; when the carbocyclic aromatic ring is fused to a heterocycle, the point of attachment is on the carbocyclic aromatic ring, and when the carbocyclic aromatic ring is fused to a cycloalkyl group, the point of attachment may be on the carbocyclic aromatic ring or on the cycloalkyl group. Divalent radicals formed from substituted benzene derivatives and having free valences on ring atoms are called substituted phenylene radicals. In monovalent polycyclic hydrocarbon radicals whose names end in "yl", divalent radicals derived by removing one hydrogen atom from a carbon atom having a free valence are named by adding "idene" to the name of the corresponding monovalent radical, e.g., a naphthyl group having two points of attachment is called naphthylidene.

[0029] The term "heteroaryl" refers to groups selected from the following: aromatic, 5-7 membered, e.g., 5-6 membered, monocyclic groups containing 1, 2, 3 or 4 heteroatoms selected from N, O and S, with the remaining ring atoms being carbon; bicyclic groups containing 8-12 membered, bicyclic groups containing 1, 2, 3 or 4 heteroatoms selected from N, O and S, with the remaining ring atoms being carbon, in which at least one ring is aromatic and at least one heteroatom is present in the aromatic ring; and tricyclic groups containing 1, 2, 3 or 4 heteroatoms selected from N, O and S, with the remaining ring atoms being carbon, in which at least one ring is aromatic and at least one heteroatom is present in the aromatic ring.

[0030] For example, heteroaryl groups include 5- to 7-membered heteroaromatic rings fused to 5- to 7-membered cycloalkyl rings. In such fused bicyclic heteroaryl ring systems, in which only one ring contains at least one heteroatom, the point of attachment may be at the heteroaromatic ring or at the cycloalkyl ring.

[0031] When the total number of S and O atoms in a heteroaryl group exceeds 1, these heteroatoms are not adjacent to one another. In some embodiments, the total number of S and O atoms in a heteroaryl group is 2 or less. In some embodiments, the total number of S and O atoms in an aromatic heterocycle is 1 or less.

[0032] Examples of heteroaryl groups (numbered from the position of attachment 1) include pyridyl (e.g., 2-pyridyl, 3-pyridyl or 4-pyridyl), cinnolinyl, pyrazinyl, 2,4-pyrimidinyl, 3,5-pyrimidinyl, 2,4-imidazolyl, imidazopyridinyl, isoxazolyl, oxazolyl, thiazolyl, isothiazolyl, thiadiazolyl, tetrazolyl, thienyl, triazinyl, benzothienyl, furyl, benzofuryl, benzimidazolyl, indolyl, isoindolyl, indolinyl, phthalazinyl, pyrazinyl, pyridazinyl, pyrrolyl, triazolyl, quinolinyl, isoquinolinyl, pyrazolyl, pyrrolopyridinyl (e.g., 1H-pyrrolo[2,3-b]pyridin-5-yl), pyrazolopyridinyl (e.g., 1H-pyrazolo[3,4-b]pyridinyl), and the like. benzo[d]thiazol-5-yl), benzoxazolyl (e.g. benzo[d]oxazol-6-yl), pteridinyl, purinyl, 1-oxa-2,3-diazolyl, 1-oxa-2,4-diazolyl, 1-oxa-2,5-diazolyl, 1-oxa-3,4-diazolyl, 1-thia-2,3-diazolyl, 1-thia-2,4-diazolyl, 1-thia-2,5-diazolyl, 1-thia-3,4-diazolyl, furazanyl, benzofurazanyl, benzothiophenyl, benzothiazolyl, benzoxazolyl, quinazolinyl, quinoxalinyl, naphthyridinyl, furopyridinyl, benzothiazolyl (e.g. benzo[d]thiazol-6-yl), indazolyl (e.g. 1H-indazol-5-yl), and 5,6,7,8-tetrahydroisoquinoline.

[0033] Some of the compounds of the present invention may have different points of attachment of hydrogen, and such compounds are called tautomers. For example, compounds having a carbonyl -CH2C(O)- group (keto form) may form a hydroxyl -CH=C(OH)- group (enol form) by tautomerism. Where applicable, both the keto and enol forms are intended to be included, either individually, and mixtures of the keto and enol forms.

[0034] The compounds, tautomers, hydrates or pharma- ceutically acceptable salts of the present disclosure may have asymmetric centers and therefore may exist as enantiomers. For example, when the compounds of the present invention have two or more asymmetric centers, they may further exist as diastereomers. Enantiomers and diastereomers are included in the broader definition of stereoisomers. All possible stereoisomers, such as substantially purely resolved enantiomers, racemic mixtures thereof, and mixtures of diastereomers, are intended to be included in this disclosure. Also, all stereoisomers of the compounds, tautomers, hydrates and pharma- ceutically acceptable salts thereof of the present invention are intended to be included in the present invention. Unless otherwise specified herein, reference to one isomer shall apply to all possible isomers. If the isomeric composition is not specified, all possible isomers shall be included.

[0035] Diastereomeric mixtures can be separated into their individual diastereomers based on their physical chemical differences by methods known to those skilled in the art, such as chromatography and / or fractional crystallization. The enantiomers can be separated by converting the enantiomeric mixture into a diastereomeric mixture by reaction with a suitable optically active compound (e.g., a chiral auxiliary such as a chiral alcohol or Mosher's acid chloride), separating the diastereomers, and converting each diastereomer into its corresponding pure enantiomer (e.g., by hydrolysis). Enantiomers can also be separated using a chiral HPLC column.

[0036] Single stereoisomers (e.g., substantially pure enantiomers) may be obtained by resolution of a racemic mixture using methods such as the formation of diastereomers using an optically active resolving agent. Racemic mixtures of chiral compounds of the present disclosure can be separated and isolated by appropriate methods, including, for example, (1) formation of ionic diastereomeric salts with chiral compounds and separation by fractional crystallization or other methods, (2) formation of diastereomeric compounds with chiral derivatizing agents, separation of the diastereomers, and conversion to pure stereoisomers, and (3) direct separation of substantially pure or enriched stereoisomers under chiral conditions.

An example of a delivery system for inhalation may be a metered dose inhalation (MDI) aerosol, which may be formulated as a suspension or solution containing the compounds, tautomers, hydrates, stereoisomers or pharma- ceutically acceptable salts described herein in at least one suitable propellant, such as selected from fluorocarbons and hydrocarbons.

[0108] For ocular administration, the ophthalmic formulations may be formulated as suspensions or solutions of the compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts described herein in an appropriate weight percentage in an appropriate ophthalmic solvent, which maintains contact of the compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts described herein with the ocular surface for a sufficient period of time to allow the compounds to penetrate the cornea and interior regions of the eye.

[0109] Pharmaceutical dosage forms useful for administration of the compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts described herein include, but are not limited to, hard gelatin capsules, soft gelatin capsules, tablets, parenteral injectables, and oral suspensions.

[0110] The term "unit dosage form" refers to a physically separate unit suitable as a unitary dose for human subjects and other mammals, each unit containing a predetermined amount of active agent calculated to produce a desired therapeutic effect, and suitable pharmaceutical excipients. Typical unit dosage forms include ampoules or syringes filled with premeasured amounts of liquid compositions, or pills, tablets, capsules, lozenges, and the like, in the case of solid compositions. In such compositions, the mimetic is usually a minor component (about 0.1 to about 50% by weight, or preferably about 1 to about 40% by weight), with processing aids and various vehicles or carriers to facilitate the formation of the desired dosage form making up the remainder. The unit dosage formulation is preferably about 5 mg, about 10 mg, about 25 mg, about 50 mg, about 100 mg, about 250 mg, about 500 mg, or about 1,000 mg per unit. In a particular embodiment, the unit dosage forms are packaged in a multipack package suitable for successive use, for example a blister pack containing at least 6, 9 or 12 sheets of unit dosage forms.

[0111] In some embodiments, for example, a unit capsule can be prepared by filling a standard two-piece hard gelatin capsule with 100 mg of a compound, tautomer, hydrate, stereoisomer, or pharma- ceutically acceptable salt described herein, 150 mg lactose, 50 mg cellulose, and 6 mg magnesium stearate.

[0112] In some embodiments, soft gelatin capsules containing 100 mg of active ingredient can be prepared by preparing a mixture of a compound, tautomer, hydrate, stereoisomer, or pharma- ceutically acceptable salt described herein with a digestible oil, such as soybean oil, cottonseed oil, olive oil, and injecting the mixture into gelatin using a positive displacement pump. The capsules are washed and dried.

[0113] In some embodiments, for example, tablets can be prepared by conventional procedures so that a dosage unit contains 100 mg of the compound of the present invention, its stereoisomers, and pharma- ceutically acceptable salts thereof, 0.2 mg colloidal silicon dioxide, 5 mg magnesium stearate, 275 mg microcrystalline cellulose, 11 mg starch, and 98.8 mg lactose. Appropriate coatings may be applied to improve palatability or delay absorption.

[0114] In some embodiments, a parenteral composition suitable for administration by injection can be prepared by stirring 1.5% by weight of a compound disclosed herein and / or at least one of its enantiomers, diastereomers, or pharma- ceutically acceptable salts in 10% by volume propylene glycol, the solution being made up to the desired volume with water for injection and sterilized.

[0115] In some embodiments, aqueous suspensions for oral administration can be prepared. For example, 5 mL of aqueous suspensions each containing 100 mg of micronized compound of the present invention, its stereoisomers, and their pharma- ceutically acceptable salts, 100 mg of sodium carboxymethylcellulose, 5 mg of sodium benzoate, 1.0 g of sorbitol solution (USP), and 0.025 mL of vanillin can be used.

[0116] When the compounds, tautomers, hydrates, stereoisomers or pharma- ceutically acceptable salts described herein are administered stepwise or together with at least one other therapeutic agent, the same dosage form can usually be used. When the drugs are administered in physical combination, the dosage form and the administration route should be selected according to the compatibility of the drugs to be combined. Thus, the term "co-administration" is understood to include simultaneous or sequential administration of at least two drugs, or administration as a fixed dose combination of at least two active ingredients.

[0117] The compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts disclosed herein can be administered as the sole active ingredient or can be administered in combination with at least one second active ingredient.

[0118] The compounds, tautomers, hydrates, stereoisomers or pharmaceutically acceptable salts described herein are incorporated into pharmaceutical compositions or formulations. These compositions will include pharmaceutically acceptable diluents and / or carriers, i.e., diluents or carriers that are physiologically compatible and substantially free of pathogenic impurities. Suitable excipients or carriers and methods for preparing administrable compositions will be known or apparent to those skilled in the art and are described in further detail in publications such as Remington's Pharmaceutical Science, Mack Publishing Co, NJ (1991). These compositions may be in the form of controlled release or sustained release compositions as known in the art. In many applications, the compounds, tautomers, hydrates, stereoisomers or pharmaceutically acceptable salts described herein are administered in the morning / midday with a rest period at night.

[0119] The compounds, tautomers, hydrates, or stereoisomers described herein may be used as such or in the form of a pharma- ceutically acceptable salt, such as hydrochloride, hydrobromide, acetate, sulfate, citrate, carbonate, trifluoroacetate, etc. In the case where the compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts described herein have relatively acidic functionality, the salt can be obtained by adding a desired base in a solventless or suitable inert solvent. Examples of pharma-ceutically acceptable base addition salts include sodium salts, potassium salts, calcium salts, ammonium salts, organic amino salts, magnesium salts, etc. In the case where the compounds, tautomers, hydrates, or stereoisomers described herein have relatively basic functionality, the salt can be obtained by adding a desired acid in a solventless or suitable inert solvent. Examples of pharma- ceutically acceptable acid addition salts include salts derived from inorganic acids such as hydrochloric acid, hydrobromic acid, nitric acid, carbonic acid, bicarbonate, phosphoric acid, monohydrogen phosphate, dihydrogen phosphate, sulfuric acid, monohydrogen sulfate, hydroiodic acid, phosphorous acid, and the like, and salts derived from relatively non-toxic organic acids such as acetic acid, propionic acid, isobutyric acid, maleic acid, malonic acid, benzoic acid, succinic acid, suberic acid, fumaric acid, lactic acid, mandelic acid, phthalic acid, benzenesulfonic acid, p-tolylsulfonic acid, citric acid, tartaric acid, methanesulfonic acid, and the like. Also included are salts of amino acids such as arginate, and salts of organic acids such as glucuronic acid or galacturonic acid (see, e.g., Berge et al., "Pharmaceutical Salts", Journal of Pharmaceutical Science, 1977, 66, 1-19).

[0120] The neutral forms of the pharma- ceutically acceptable salts described herein may be regenerated by contacting the salt with a base or acid and isolating the parent compound in the conventional manner.

[0121] This disclosure provides prodrugs, which are compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts described herein that readily undergo chemical changes under physiological conditions to provide compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts of the present disclosure. Furthermore, prodrugs can be converted to the disclosed compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts by chemical or biochemical methods in an ex vivo environment. For example, prodrugs can be slowly converted to the disclosed compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts when placed in a transdermal patch reservoir with an appropriate enzyme or chemical reagent. Prodrugs are often useful in some situations because they are easier to administer than the parent drug. For example, prodrugs may have better oral bioavailability than the parent drug. Prodrugs may also have improved solubility in pharmacological compositions compared to the parent drug. Various prodrug derivatives are known in the art, including, for example, prodrugs that utilize hydrolysis or oxidative activation. Examples of prodrugs include, but are not limited to, compounds of the invention that are administered as esters ("prodrugs") and then metabolically hydrolyzed to the active carboxylic acid.

[0122] Certain compounds, tautomers, stereoisomers, or pharma- ceutically acceptable salts of the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms.Certain compounds, tautomers, hydrates, stereoisomers, or pharma- ceutically acceptable salts of the present disclosure can exist in multiple crystalline or amorphous forms.

[0123] Certain compounds, tautomers, hydrates, or pharma- ceutically acceptable salts in this disclosure possess asymmetric carbon atoms (optical centers) or double bonds; the racemates, enantiomers, diastereomers, geometric isomers, and individual isomers are intended to be encompassed within the scope of the present disclosure to the extent possible.

Cell Seeding of HT-29 Cells 1) HT-29 cells were checked daily to ensure they were healthy and growing as expected. These cells were subcultured when they were approximately 80% confluent. 2) First, pre-warm the culture medium, McCoy's 5A medium (Gibco, Catalog No. 16600-082) containing 10% FBS (Gibco, Catalog No. 10099-141C), in a 37°C water bath for at least 30 minutes. 3) Grow cells in a T75 flask to the desired confluency level of 80%, aspirate media and wash twice with warm PBS. 4) Add 2-3 mL of fresh warm trypsin (Gibco, Catalog No. 25200-056) solution. Transfer the flask to a 37°C incubator. 5) After 5 minutes, gently tap the side of the flask and examine the flask under the microscope for lifting. If necessary, return the cells to the incubator for an additional 5-10 minutes, tapping occasionally, until lifting is complete. 6) Quickly neutralize the trypsin reaction by adding 6-9 mL of cell culture medium and then transfer the cells to a sterile 15 mL conical tube. Pellet the cells by centrifugation at 300 x g for 7 minutes and then decant the supernatant. 7) Resuspend the cells in fresh cell culture medium. Count the cells using a hemocytometer. 8) Seed 5,000 cells in 100 μL per well of a sterile 96-well cell culture plate (Corning 3903) and culture overnight at 37°C, 5% CO2.

[0352] 3. Compound titration and treatment of HT-29 cells 1) All batches of compounds (CPDs0) (e.g., compounds 1-169) were dissolved in DMSO (dimethyl sulfoxide) as 20 mM stock solutions. 2) 3 μL of 20 mM stock solution of CPDs was placed in 27 μL of DMSO, mixed thoroughly, and titration ratio of 1:3 (20 μL of CPDs + 40 μL of DMSO) was continued until 10 points were completed to obtain solutions of CPDS, e.g., 6.6 mM, 2.2 mM, etc. 3) Remove the assay plate containing HT-29 cells from the incubator and remove all culture medium, wash once with 1x PBS, and replace with fresh McCoy's 5A medium without FBS containing a cocktail of TNF-α (10 ng / mL), SMAC mimetic compound (6 μM) and zVAD-FMK (10 μM) to stimulate HT-29 cells to increase pRIPK1 levels and necroptosis. 4) Add 0.5 μL of diluted compounds to corresponding 96-well assay plates. 5) Incubate the assay plate at 37°C, 5% CO2 for 20 hours.

[0353] 4. Performing cell viability detection of HT-29 cells after compound treatment 1) The CellTiter-Glo® Luminescent Cell Viability Assay was used to detect ATP levels in viable HT-29 cells. 2) Bring CellTiter-Glo® buffer and lyophilized substrate to room temperature before use. 3) Resuspend CellTiter-Glo® Substrate in CellTiter-Glo® Buffer and mix by gently vortexing to obtain a homogenous solution. 4) Pipette 20 μL of the enzyme / substrate mixture using a multichannel pipette into the 96-well assay plate for step 5) of the compound titration and treatment stage. 5) Place the plate on an orbital shaker and mix the contents for 3 minutes to induce cell lysis. 6) The plate is then incubated at room temperature for 10 minutes to allow the luminescent signal to stabilize. 7) Read and record the luminescence signal using EnVision. 8) Geometric mean EC of the compound 50 was calculated from 10 response doses in duplicate. The RIP1 inhibitory activities of compounds 1-169 are summarized in Table 2. In Table 2, the activities are indicated as follows: +++=0.1 nM≦EC50<100 nM; ++=100 nM≦EC50<1000 nM; +=1000 nM≦EC50<10000 nM.
