Description

[Technical Field]

[0001] FIELD OF THE INVENTION The present invention relates to novel compounds that are inhibitors of the mitochondrial permeability transition pore (mPTP), and in particular to such compounds for use as pharmaceuticals, especially for the treatment or prevention of degenerative, neurodegenerative, or mitochondrial diseases, or other diseases or disorders in which inhibition of mPTP provides a therapeutic or prophylactic effect. [Background technology]

[0002] BACKGROUND OF THE INVENTION The mitochondrial permeability transition pore (mPTP) is activated under certain conditions of cellular stress, particularly when excessive Ca 2+ It is a high-conductance channel located on the inner mitochondrial membrane that is activated under load and oxidative stress. It is permeable to solutes with molecular weights <1.5 kDa and is sensitive to voltage and Ca. 2+ Activation of mitochondrial membrane potential (MTP)-dependent mitochondrial ATPases (MTPs) is dependent on mitochondrial activity and exhibits a characteristically large conductance. Upon activation, oxidative phosphorylation is uncoupled, resulting in loss of mitochondrial membrane potential and perturbation of mitochondrial metabolism. In addition, solutes enter the mitochondrial matrix, causing swelling and consequent release of apoptotic factors and sequestered Ca2+, which leads to rupture of the outer membrane. 2+ This is accompanied by the release of ATP, which results in cell death by apoptosis or necrosis depending on the cell type and physiology, and has therefore been implicated as a key pathological event in several degenerative and metabolic diseases.

[0003] Under normal physiological conditions, mitochondria are responsible for cellular Ca 2+ It plays an important role in regulating homeostasis. Ca enters cells through cell surface channels, a common mechanism of cell signaling. 2+ is rapidly sequestered by mitochondria and absorbs excessive and toxic Ca in the cytoplasm. 2+ Accumulation of high levels of Ca is prevented. 2+In cell types such as neurons, skeletal muscle fibers, and cardiomyocytes, where there is a flux of Ca, this Ca flux is transported from mitochondria to the mitochondrion. 2+ The "buffering" function is crucial for maintaining cellular health. However, mitochondria do not retain Ca 2+ Mitochondrial Ca sequestering capacity is limited. 2+ When the level reaches a certain threshold, Ca 2+ The activation of sensitive mPTP leads to mitochondrial breakdown and initiation of cell death. Activation of mPTP in degenerative diseases can occur in various ways depending on the disease, for example: 1) excessive intracellular Ca 2+ Entry of Ca into mitochondria 2+ overload, 2) dysfunctional mitochondrial Ca 2+ Efflux mechanisms, especially Ca 2+ Ca overload 2+ 3) decreased activity of the efflux transporter NCLX, and 3) Ca in mitochondria 2+ 4) oxidative stress; and 5) sensitization of mPTP due to impaired mitochondrial function, i.e., lower intramitochondrial Ca. 2+ Activation of mPTP at high concentrations, 6) excessive Ca transport from the endoplasmic reticulum into mitochondria at the junction between two organelles known as the mitochondrial-associated membrane. 2+ This can occur when moving.

[0004] While the properties and functions of mPTP can be investigated in simple in vitro assays in isolated mitochondria, the molecular identity of mPTP remains unknown. Although multiple proteins, including ATP synthase and the adenine nucleotide translocator (ANT) protein family, have been proposed to comprise the pore-forming complex, no single protein has been widely accepted as being responsible for pore formation. However, peptidyl prolyl cis-trans isomerase F (Ppif), also known as cyclophilin D, is well accepted as a key regulator of the pore, even though it does not form a transmembrane channel by itself. Genetic or pharmacological inhibition of Ppif results in Ca 2+ It significantly reduces the sensitivity of pore opening in response to stress and other mPTP activators. Therefore, genetic disruption or pharmacological inhibition of Ppif has been utilized to evaluate the involvement of mPTP in pathological pathways in cellular and animal disease models. Thus, inhibition of mPTP has been shown to be a potential therapeutic approach for a number of diseases, particularly those related to Ca 2+ It has been shown to be protective in models of diseases in which dysregulation and oxidative stress are known to contribute to cellular degeneration. In particular, genetic knockout of Ppif was shown to be protective in various presymptomatic in vivo transgenic models of neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, and motor neuron disease. This demonstrates the therapeutic potential of mPTP inhibition. In each of these diseases, genetic mutations, particularly proteins that cause inherited forms of the disease (i.e., amyloid precursor protein, α-synuclein, and superoxide dismutase 1, respectively) and are expressed in mouse models, inhibit the transport of Ca into mitochondria. 2+ It has been shown that mitochondrial Ca2+ induces either overload or sensitization of the mPTP. Recent evidence suggests that this may occur by a common mechanism in Alzheimer's disease, Parkinson's disease, and Friedreich's ataxia. In each case, mitochondrial Ca2+ is increased in cells expressing mutant disease-associated proteins (amyloid precursor protein, PINK1, and frataxin, respectively).2+ The activity or expression of the efflux transporter NCLX is reduced, which prevents the entry of Ca into mitochondria. 2+ In the case of Parkinson's disease, it has also been shown that pathological aggregated forms of the protein α-synuclein, a misfolded protein commonly found in sporadic and inherited cases of Parkinson's disease, sensitize or activate the mPTP.

[0005] Genetic disruption of Ppif has been shown to be beneficial in presymptomatic models of a number of other degenerative diseases, thus indicating the potential of mPTP inhibitors in Duchenne and congenital forms of muscular dystrophy, ischemia-reperfusion injury, bone repair, pancreatitis, and other related disorders, among others.

[0006] In addition to the demonstrated benefits of Ppif inhibition in presymptomatic models, mPTP function has been shown to be dysregulated in multiple other disease indications. In particular, in several diseases, Ca 2+ The threshold for mPTP activation in response to stress appears to be sensitized, suggesting that aberrant mPTP activation can occur under physiological conditions and that mPTP activation drives tissue degeneration. For example, in muscle mitochondria from aged human muscle biopsies, the threshold for mPTP activation is reduced compared to healthy controls. This sensitization of mPTP activity in these diseases provides an additional rationale for the therapeutic potential of mPTP inhibitors.

[0007] In addition, mPTP inhibitors may be effective in preventing mitochondrial dysfunction, oxidative stress, inflammatory stress, or Ca 2+ It may also have therapeutic potential in other diseases where dysregulation occurs during the pathogenesis of the disease.

[0008] The discovery and development of mPTP inhibitors has primarily focused on identifying Ppif inhibitors. Cyclosporin A (CsA), originally identified as an immunosuppressant due to its inhibitory activity against calcineurin, was also found to inhibit Ppif, as well as other members of the peptidyl prolyl cis-trans isomerase (Ppi) enzyme family. Subsequently, several cyclosporin A derivatives, e.g., Debio-25 and NIM811, were developed that exhibit broad activity against the Ppi enzyme family without inhibiting calcineurin. However, none of these have been marketed. To date, no potent, brain-penetrant, selective Ppif inhibitors have been reported. Another, more recent approach to discovering mPTP inhibitors utilizes phenotypic screening in isolated mitochondria. These have been successful in identifying potent small-molecule mPTP inhibitors with Ppif-independent modes of action.

[0009] Yu et al. (2020, Cell, 183, 1-14) discusses the relationship between mPTP activation and the mechanisms of TDP-43 proteinopathies, such as TDP-43-associated neurodegeneration. Cytoplasmic neuronal accumulation of TDP-43, a normally nuclear protein, characterizes almost all ALS cases and 40-50% of frontotemporal lobar degeneration (FTLD), with some familial cases caused by mutant forms of the protein. Both diseases are associated with a neuroinflammatory cytokine profile associated with upregulation of the NF-κB and type I IFN pathways, directly suggesting a role for TDP-43 in neuroinflammation. Mutant or overexpressed wild-type TDP-43 in neurons mislocalizes to mitochondria and induces the release of mitochondrial DNA (mtDNA) into the cytoplasm. This mtDNA then activates cGAS-STING, an immune sensor that triggers the induction of innate immune genes such as IL-6, TNFα, and interferon-β. Inhibition of mPTP with cyclosporine A or by CypD knockout prevents TDP-43-induced release of mtDNA and the subsequent induction of innate immune response genes. Furthermore, inhibition of cGAS-STING extends the survival of mutant mice expressing mutant TDP-43. This data implicates mPTP activation in mediating the toxic effects of TDP-43 in ALS and other diseases in which either mutations in the TDP-43 gene cause the disease or TDP-43 proteinopathy is present.

[0010] A paper by Jang et al. (2021 American Journal of Physiology: Renal physiology, doi: 10.1152 / ajprenal.00171.2021. Epub ahead of print. PMID: 34396791) highlights the potential therapeutic benefit of mPTP inhibition (via CypD knockout) in a mouse model of renal fibrosis. Renal fibrosis was induced in wild-type and CypD-KO mice using unilateral ureteral obstruction. Markers of inflammation, proximal tubular atrophy, and fibrosis were reduced in CypD-KO mice compared with wild-type mice. Measures of fibrosis included collagen deposition, α-SMA and TGF-β expression, and interstitial cell proliferation. This highlights the potential role of mPTP in cell injury / death-mediated tissue remodeling and fibrosis. Therefore, mPTP inhibitors may be beneficial in diseases in which fibrosis is a key pathological mechanism, such as chronic kidney disease, idiopathic pulmonary fibrosis, nonalcoholic steatohepatitis, primary biliary cholangitis, and systemic sclerosis.

[0011] CYP2D6 is one of the major members of the human drug-metabolizing cytochrome P450 enzyme system. It is responsible for the hepatic metabolism of a significant proportion of clinically used drugs. Inhibition of CYP2D6 can promote drug-drug interactions with co-prescribed drugs metabolized by the same enzyme, potentially resulting in increased plasma concentrations to levels that can cause adverse effects. CYP2D6 is primarily expressed in the liver and, to a lesser extent, in the central nervous system (CNS). In the CNS, it is involved in the synthesis of various neurotransmitters, including dopamine. Consequently, inhibition of CYP2D6, particularly at the CNS level, can potentially have adverse effects through impaired pathways such as dopamine production. In Parkinson's disease, characterized by loss of dopaminergic neurons in the substantia nigra, further depletion of dopamine levels through CYP2D6 inhibition may not be tolerated.

[0012] When administered orally, the oral bioavailability and systemic exposure of a drug are largely determined by the extent of absorption from the gastrointestinal tract and the extent of first-pass metabolism in the liver. Therefore, properties such as high solubility (measured in phosphate-buffered saline (PBS) or the more biologically relevant fasting simulated intestinal fluid (FaSSIF)) and high metabolic stability (measured in vitro in either isolated liver microsomes or hepatocytes from rats and humans) can be used to predict improved oral bioavailability and / or systemic exposure in patients.

[0013] WO2010 / 049768 relates to acrylamide derivatives and their use as therapeutic agents, particularly for the prevention and / or treatment of diseases associated with mPTP activity (see also Plyte et al., J. Med Chem. 2014, 57, 5333-47). Chen et al. (Assay and Drug Development Technologies, 2018, 16, 445-455) relates to phenotypic screening of mPTP modulators using platelets and discloses additional acrylamide derivatives. CA2884607A1 relates to acrylamide and maleimide compounds said to be useful in the treatment of mitochondrial diseases.

[0014] There remains a need to discover additional compounds that are inhibitors of mPTP, particularly those that combine mPTP inhibition with low CYP2D6 inhibition. Such compounds may also exhibit other desirable pharmacological properties, such as improved oral bioavailability and / or improved systemic exposure. Summary of the Invention

[0132] The definition of a compound of formula (I) is intended to include all tautomers of the compound.

[0133] The compounds of the present invention may be provided in the form of their pharmaceutically acceptable salts and / or solvates. In particular, the compounds of formula (I) may be provided in the form of their pharmaceutically acceptable salts and / or solvates, e.g., pharmaceutically acceptable salts.

[0134] It will be recognized that for use in medicine, salts of compounds of formula (I) should be pharmaceutically acceptable. Non-pharmaceutically acceptable salts of compounds of formula (I) may be useful in other contexts, such as during the preparation of compounds of formula (I). Suitable pharmaceutically acceptable salts will be apparent to those skilled in the art. Pharmaceutically acceptable salts include those described in Berge et al. (1977). Such pharmaceutically acceptable salts include acid and base addition salts. Pharmaceutically acceptable acid addition salts can be formed with inorganic acids, such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, or phosphoric acid, and organic acids, such as succinic acid, maleic acid, acetic acid, fumaric acid, citric acid, tartaric acid, benzoic acid, p-toluenesulfonic acid, methanesulfonic acid, or naphthalenesulfonic acid. Other salts, such as oxalates or formates, may be used, for example, in the isolation of compounds of formula (I) and are within the scope of the present invention.

[0135] Certain compounds of formula (I) may form acid or base addition salts with one or more equivalents of the acid or base, and the present invention includes within its scope all possible stoichiometric and non-stoichiometric forms.

[0136] The compounds of formula (I) may be prepared in crystalline or non-crystalline form. If crystalline, the compounds of formula (I) may optionally be solvated, for example as hydrates. The present invention includes within its scope stoichiometric solvates (e.g., hydrates) as well as compounds containing variable amounts of solvent (e.g., water).

[0137] The present invention should be understood to encompass all isomers of formula (I) and their pharmaceutically acceptable derivatives, including all geometric, tautomeric, and optical forms, and mixtures thereof (e.g., racemic mixtures). When additional chiral centers are present in compounds of formula (I), the present invention includes within its scope all possible diastereoisomers, including mixtures thereof. The different isomeric forms may be separated or resolved one from the other by conventional methods. Alternatively, any isomer may be obtained by conventional synthetic methods or by stereospecific or asymmetric syntheses.

[0138] The present disclosure includes all isotopic forms of the compounds of the present invention provided herein, whether (i) in a form in which all atoms of a given atomic number have a mass number (or mixture of mass numbers) that is predominant in nature (referred to herein as a "natural isotopic form") or (ii) in a form in which one or more atoms are replaced by an atom having the same atomic number but a mass number that is different from the mass number of the atom that is predominant in nature (referred to herein as a "non-natural variant isotopic form"). It is understood that atoms may naturally occur as a mixture of mass numbers. The term "non-natural variant isotopic form" also includes embodiments in which the proportion of atoms of a given atomic number that have mass numbers that are less common in nature (referred to herein as "rare isotopes") is increased compared to the proportion occurring in nature, for example, to a level of >20%, >50%, >75%, >90%, >95%, or >99% of the number of atoms of that atomic number (the latter embodiment being referred to as an "isotopically enriched variant form"). The term "non-natural variant isotopic form" also includes embodiments in which the proportion of a rare isotope is reduced compared to the proportion occurring in nature. Isotopic forms can include radioactive forms (i.e., which incorporate a radioactive isotope) and non-radioactive forms. Radioactive forms are typically isotopically enriched variant forms.

[0139] Thus, non-naturally occurring variant isotopic forms of a compound may contain deuterium ( 2 H or D), carbon-11 (11 C), carbon-13( 13 C), carbon-14( 14 C), nitrogen-13( 13 N), nitrogen-15( 15 N), oxygen-15( 15 O), oxygen-17( 17 O), oxygen-18( 18 O), phosphorus-32( 32 P), sulfur-35( 35 S), chlorine-36( 36 Cl), chlorine-37( 37 Cl), fluorine-18( 18 F), iodine-123( 123 I), iodine-125( 125 It may contain one or more artificial or rare isotopes, such as I), or may contain an increased proportion of such isotopes at one or more atoms compared to the proportion that predominates in nature.

[0140] Non-natural variant isotopic forms containing radioactive isotopes may be used, for example, for drug and / or substrate tissue distribution studies. The radioactive isotope tritium, i.e. 3 H, and carbon-14, i.e., 14 C are particularly useful for this purpose given their ease of incorporation and ready means of detection. 2 Non-natural variant isotopic forms incorporating H or D may offer certain therapeutic advantages due to greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements, and therefore may be preferred in certain circumstances. 11 C. 18 F, 15 O, and 13 Non-natural variant isotopic forms can be prepared incorporating positron emitting isotopes, such as N, which can be useful in positron emission tissue distribution (PET) studies to examine substrate receptor occupancy.

[0141] In one embodiment, the compounds of the invention are provided in natural isotopic form.

[0142] In one embodiment, the compounds of the present invention are provided in non-natural variant isotopic forms. In a specific embodiment, non-natural variant isotopic forms are those in which deuterium (i.e., 2 In one embodiment, the atoms of the compounds of the present invention are in a non-radioactive isotopic form. In one embodiment, one or more atoms of the compounds of the present invention are in a radioactive isotopic form. Preferably, the radioisotope is a stable isotope. Preferably, the non-natural variant isotopic form is a pharmaceutically acceptable form.

[0143] In one embodiment, compounds of the present invention are provided in which a single atom of the compound exists in a non-natural variant isotopic form. In another embodiment, compounds of the present invention are provided in which two or more atoms exist in a non-natural variant isotopic form.

[0221] Although the most suitable route will depend, for example, on the condition and disorder of the recipient, pharmaceutical formulations according to the present invention include those suitable for oral administration, parenteral administration (including subcutaneous, intradermal, intramuscular, intravenous (bolus or infusion), and intraarticular), intranasal (also known as intranasal), inhalation administration (including fine particle dusts or mists that may be generated by various types of pressurized metered dose aerosols, nebulizers, or inhalers), insufflation, rectal, intraperitoneal, topical administration (including cutaneous, buccal, sublingual, and intraocular), and intrathecal administration.

[0222] Preferred pharmaceutical formulations according to the present invention are those suitable for oral, intrathecal, and parenteral administration; more preferably, those suitable for oral or intrathecal administration.

[0223] In a preferred embodiment, the compound according to formula (I) is administered by intrathecal administration.This method of administration involves injecting the compound of the present invention into the spinal canal or intrathecal space, so that it reaches the cerebrospinal fluid.This is advantageous for administering compounds that may not be able to cross the blood-brain barrier by other routes of administration, such as oral administration.

[0224] Suitable pharmaceutical formulations can be administered intrathecally by continuous infusion, such as with a catheter or pump, or by single bolus injection or intermittent bolus injection. For intrathecal administration, the pharmaceutical composition can be administered continuously or intermittently. Intermittent administration can be, for example, every 30 minutes, every hour, every few hours, every 24 hours, every few days (e.g., every 48 hours or 72 hours), or any combination thereof.

[0225] When the pharmaceutical formulations of the present invention are administered continuously, an implantable delivery device, such as an implantable pump, can be employed. Examples of such delivery devices include devices that can be implanted subcutaneously in the body or skull and provide an access port through which the pharmaceutical formulation can be delivered to a nerve or the brain.

[0226] When used for the indicated effects, the intrathecal dosage of the present invention will typically be less than 1 mg, such as less than 500 μg / kg body weight, for example, less than 250 μg / kg, when administered in a single dose or intermittently to an adult human. When administered continuously, the intrathecal dosage of the present invention will typically be less than 250 μg / kg body weight per hour, such as less than 125 μg / kg body weight per hour, for an adult human.

[0227] In another preferred embodiment, the compounds according to Formula (I) are administered intranasally, by inhalation (including fine particle dusts or mists that can be generated by various types of pressurized metered-dose aerosols, nebulizers, or inhalers), or by insufflation. Such methods of administration allow for lower doses of the compounds of the invention to be administered, which may lead to fewer side effects. For example, daily doses of the compounds of the invention ranging from 10 to 0.01 μg, preferably 1 to 0.01 μg, and more preferably about 0.1 μg (100 ng) may be used.

[0228] The formulations can be conveniently provided in unit dosage form and can be prepared by any of the methods well known in the art of pharmacy.All methods include the step of combining the active ingredient with the carrier, which constitutes one or more accessory ingredients.In general, the formulations are prepared by uniformly and intimately combining the active ingredient with a liquid carrier or a finely divided solid carrier, or both, and then, if necessary, shaping the product into the desired formulation.

[0229] Formulations of the present invention suitable for oral administration may be presented as discrete units such as capsules, cachets, pills, or tablets, each containing a predetermined amount of the active ingredient; as a powder or granules; as a solution or suspension in an aqueous liquid or non-aqueous liquid, for example, an elixir, tincture, suspension, or syrup; or as an oil-in-water or water-in-oil emulsion. The active ingredient may also be presented as a bolus, electuary, or paste.

[0230] Tablets may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared by compressing the active ingredient in a free-flowing form, such as a powder or granules, optionally mixed with a binder, lubricant, inert diluent, lubricant, surfactant, or dispersant, in a suitable machine. Molded tablets may be made by molding a mixture of powdered compound moistened with an inert liquid diluent in a suitable machine. The tablets may optionally be coated or scored, and may be formulated to provide slow or controlled release of the active ingredient therein. The compounds of formula (I) can be administered, for example, in a form suitable for immediate release or sustained release. Immediate release or sustained release can be achieved by using a suitable pharmaceutical composition containing the compound of the present invention, or, particularly in the case of sustained release, by using devices such as subcutaneous implants or osmotic pumps. The compounds of the present invention may also be administered liposomally.

[0392] Biological Examples Biological Example 1 - mPTP Activity Assay in Isolated Rat Liver Mitochondria, Human Platelet Mitochondria, and Isolated Rat Brain Mitochondria (Rat liver mitochondrial assay) Pharmacological inhibition or modulation of mPTP has been demonstrated using well-characterized "Ca"-dependent ATPases performed in isolated mitochondria. 2+ In vitro, isolated mitochondria can measure intramitochondrial Ca retention in a mitochondrial Ca2+ / Ca ... 2+ Exogenous Ca concentration is increased until it reaches the threshold for mPTP activation. 2+ When the pore is activated, mitochondrial integrity is compromised and stored Ca is released. 2+ Ca is released from inside and outside the mitochondrial compartment. 2+ The partitioning of Ca into membrane-impermeable Ca 2+ Depending on the assay configuration, inhibition or modulation of mPTP can delay pore opening or increase the Ca concentration required to induce mPTP opening. 2+ or increasing the concentration of

[0393] mPTP activity was measured in mitochondria freshly isolated from female Sprague Dawley (250-300 gram) rat livers using the following method. Cervical dislocation was performed on the rats. The livers were then perfused in situ with approximately 40 ml of cold Dulbecco's phosphate-buffered saline (DPBS) and then dissected and transferred to 30 ml of isolation buffer (250 mM sucrose, 10 mM KCl, 1 mM EGTA, 1 mM EDTA, 25 mM HEPES, pH adjusted to 7.5 with 1 M NaOH). Each liver lobe was then removed from the buffer and minced into approximately 5 mm pieces using forceps and a scalpel, then transferred to a 50 ml Potterton-Dounce homogenization tube on ice containing 30 ml of ice-cold centrifugation buffer (300 mM trehalose, 25 mM HEPES, 1 mM EGTA, 1 mM EDTA, 10 mM KCl, pH adjusted to 7.5 with 1 M NaOH, and supplemented with 0.1% bovine serum albumin (BSA) and complete protease inhibitor cocktail (one inhibitor tablet per 50 ml of buffer)). Homogenization was performed at 1800 rpm using a Teflon pestle. The slurry was centrifuged at 800 g for 10 min at 4°C, and the supernatant was then centrifuged at 10,000 g for 10 min. The pellet was washed once with FLIPR assay buffer (75 mM mannitol, 25 mM sucrose, 5 mM potassium phosphate monobasic, 20 mM Tris base, 100 mM KCl, 0.1% BSA, pH adjusted to 7.4 with 5 M HCl), centrifuged again, and then resuspended in FLIPR assay buffer to a concentration of 8.8 mg / ml protein.

[0394] Test compounds (10 mM stock in DMSO) were serially diluted in half-log increments into DMSO to generate 10 test concentrations (final concentrations in the assay, 30 μM to 1 nM). Intermediate dilutions of 5 μl of DMSO sample into 247 μl of FLIPR assay buffer were performed, followed by transfer of 5 μl to duplicate wells of a 384-well polypropylene assay plate. Control wells contained 0.5% (v / v) DMSO and 5 μM cyclosporine A.

[0395] A mitochondria / Fluo5N assay stock solution was prepared in 5.6 ml of FLIPR assay buffer (room temperature) supplemented with succinic acid disodium salt (10 mM), rotenone (1 μM), Fluo5N pentapotassium salt (2 μM), and 1 ml of mitochondrial suspension. 15 μl was then transferred into the assay plate containing the test compound and incubated for 10 minutes at room temperature. The assay plate was then transferred to a FLIPR Tetra plate reader (Molecular Devices). Dye fluorescence was then measured every 3 seconds for a total of 10 minutes. After 12 seconds, a 2.5 μl bolus of CaCl (75 μM) was added from the source plate containing 675 μM CaCl in FLIPR assay buffer. IC values ​​for the test compounds were calculated using the fluorescence values ​​collected at 10 minutes. Percent inhibition was calculated using the DMSO control and cyclosporine A values ​​as 100 and 0%, respectively.

[0396] (Human platelet mitochondrial assay) The mPTP cell-based assay was performed in stimulated human platelets using a mitochondrial membrane potential flow cytometry assay. Platelets were simulated by Ca transport across the platelet membrane. 2+ This then leads to a rapid influx of Ca 2+ is sequestered by mitochondria until a threshold for mPTP opening is reached, at which point a pore opens and the mitochondrial membrane potential is lost. Changes in mitochondrial membrane potential due to mPTP opening can be quantified in living platelets using standard mitochondrial membrane potential dyes, such as 3,3'-dihexyloxacarbocyanine iodide (DiOC6(3)), allowing for the pharmacological characterization of mPTP inhibitors.

[0397] Fresh human blood (20 ml) was collected from consenting donors in 3.2% sodium citrate. Platelets were isolated by centrifugation at 200 g for 20 minutes at room temperature, and the platelet-rich plasma layer was then transferred to a new tube. Prostaglandin 12 was added to the platelets at a final concentration of 20 ng / ml. After centrifugation at 640 g for 10 minutes, the platelet-rich pellet was resuspended in 4 ml of HEPES assay buffer (137 mM NaCl, 2.7 mM KCl, 11.9 mM NaHCO 3 , 0.42 mM NaH 2 PO 4 , 1 mM MgCl 2 , 5.5 mM glucose, 0.1% bovine serum albumin, 10 mM HEPES, pH adjusted to 7.4) and stored on ice.

[0398] Test compounds were prepared from 10 mM stocks in DMSO and serially diluted in assay buffer containing 0.4% DMSO. 25 μl was transferred to a 96-well plate. Platelets were loaded with the mitochondrial membrane potential dye DiOC6(3) (3,3'-dihexyloxacarbocyanine iodide; Invitrogen) at 200 nM for 30 minutes. 50 μl was then plated into each well of the 96-well plate containing the diluted test compound and incubated for 15 minutes. Control wells contained DMSO (0.1% final concentration) only or 5 μM cyclosporin A. Platelets were then stimulated with the addition of 25 μl of assay buffer containing CaCl, α-thrombin, and convulxin at final concentrations of 2 mM, 0.017 U / ml, and 0.167 μg / ml, respectively, and incubated for 14 minutes. The reaction was stopped by adding 25 μl of 15 mM EDTA in assay buffer. The mitochondrial membrane potential of the entire platelet population in each well was then quantified by flow cytometry using a Guava easyCyte 5 benchtop flow cytometer with 3000 events per well. The percentage of platelets with depolarized mitochondrial membrane potential was calculated for each well. The pIC50 of each compound was then calculated using a standard four-parameter curve-fitting model (GraphPad Prism).

[0399] (Rat brain mitochondrial assay) mPTP activity was measured in freshly isolated brain mitochondria from female Sprague-Dawley (250-300 grams) rats. Anesthetized rats were perfused in situ with approximately 40 ml of cold Dulbecco's phosphate-buffered saline (DPBS), and then the brains were dissected and transferred to 30 ml of isolation buffer (225 mM mannitol, 75 mM sucrose, 1 mM EGTA, pH 7.4 adjusted with 1 M NaOH). Brains were minced into approximately 5 mm fragments using forceps and a scalpel and then transferred to a 50 ml Potterton-Dounce homogenization tube on ice containing 10 ml of ice-cold isolation buffer (supplemented with complete protease inhibitors as described above; 1 tablet per 50 ml of buffer). Homogenization was performed at 1800 rpm using a Teflon pestle. The slurry was centrifuged at 2000 g for 10 min at 4° C., and the supernatant was then centrifuged at 12,000 g for 9 min. The pellet was resuspended using a Dounce homogenizer in the same isolation buffer as above, but with the addition of 0.02% digitonin, centrifuged at 12,000 g for 11 min, and finally resuspended in 5 ml of modified isolation buffer (as above, but with EGTA reduced to 0.1 mM).

[0400] Test compounds were prepared in 384-well polypropylene assay plates as described above for the liver mitochondrial assay. A stock mitochondrial / Fluo5N assay solution was prepared in 5.6 ml of assay buffer (120 mM mannitol, 40 mM MOPS, 5 mM KH2PO4, 60 mM KCl, 10 mM pyruvate, 2 mM malate, 2 mM MgCl2, 20 μM ADP, 1.26 μM oligomycin A, pH adjusted to 7.4) supplemented with Fluo5N pentapotassium salt (2 μM) and 1 ml of mitochondrial suspension. 15 μl was then transferred to the assay plate containing the test compound and incubated for 10 minutes at room temperature. The assay plate was then transferred to a FLIPR Tetra plate reader (Molecular Devices). Dye fluorescence was then measured every 3 seconds for a total of 10 minutes. After 12 seconds, a 2.5 μl bolus of Ca (75 μM) was added from the source plate containing 675 μM CaCl in FLIPR assay buffer. IC values ​​for test compounds were calculated using fluorescence values ​​collected at 10 minutes. Percent inhibition was calculated using the DMSO control and cyclosporine A values ​​as 100% and 0%, respectively.

[0401] After 24-96 hours of incubation with test compounds, general cytotoxicity was assessed in HEK293 and SHSY5Y cells using a standard cell viability method (Cell Titre Glo; Promega).

[0403] Biological Example 2 - Cytochrome P450 Assay Tests evaluating test compound-mediated inhibition of the cytochrome P450 enzyme isoform CYP2D6 were performed using human liver microsomes (BD Gentest) using either a single test compound concentration (1 μM) or a concentration response (0.1, 0.3, 1, 3, 10, and 30 μM) to derive IC50 values. Test compound solutions were prepared from 10 mM stocks in DMSO and diluted to 200 μM with DMSO. Reactions were set up in 96-deep-well plates by combining 1 μl of test compound with 179 μl of reaction mixture (100 mM phosphate-buffered saline (PBS), 0.2 mg / mL microsomes, and 2 μM dextromethorphan, prepared from stocks detailed below).

[0404] Table 2: Summary of incubation mixtures [Table 3]

[0405] The positive control inhibitor, quinidine, was used at a final concentration of 0.5 μM when used at a single concentration. The final concentrations of quinidine used to derive IC50s were 0, 0.1, 0.3, 1, 3, 10, and 30 μM. Plates were warmed to 37°C for 15 minutes, and then the reaction was initiated with 20 μl of 10 mM NADPH solution in PBS and incubated for 20 minutes at 37°C. Assays were performed in duplicate. Reactions were quenched with 200 μl of cold acetonitrile containing internal standards (200 nM labetalol, 200 nM alprazolam, and 100 nM tolbutamide). Plates were centrifuged at 4000 rpm for 30 minutes, placed on ice for 20 minutes, and then centrifuged again at 4000 rpm for 30 minutes to precipitate proteins. 100 μL of the supernatant was transferred to a new plate, diluted with 100 μL of pure water, and then analyzed using UPLC / MS / MS. The products of the conversion of dextromethorphan to dextrorphan were monitored by UPLC-MS / MS. Inhibition of CYP2D6 in human liver microsomes was measured as the percentage reduction in activity of dextrorphan production compared to the uninhibited control (=100% activity). IC 50 Values ​​(concentration of test compound producing 50% inhibition) were calculated using Excel XLfit.

[0406] (result) CYP2D6 % inhibition values ​​for certain compounds of the present invention are shown in Table 3. Table 3 also shows the CYP2D6 % inhibition value for Comparative Example 1. The results show that the test compounds exhibited significantly reduced inhibition of CYP2D6 compared to Comparative Example 1. Negative values ​​indicate no effective inhibition of CYP2D6 at a test compound concentration of 1 uM. Table 3 also shows the CYP2D6 IC values ​​for certain example compounds and Comparative Example 1. 50The % CYP2D6 inhibition values ​​are also shown. The results indicate that Comparative Example 1 is a highly potent inhibitor of CYP2D6 and is significantly more potent than the tested Example compounds. This is consistent with the potent CYP2D6 % inhibition value shown for Comparative Example 1. Therefore, the tested compounds of the present invention are expected to exhibit improved in vivo properties, such as reduced adverse drug-drug interactions and reduced inhibition of neurotransmitter production in the central nervous system, particularly dopamine.

[0408] Biological Example 3 - PBS and FaSSIF Solubility Test compounds were prepared as 10 mM stocks in DMSO, and 15 μl samples were transferred in duplicate to 1.5 mL flat-bottom glass vials (BioTech Solutions). Fasting simulated intestinal fluid (FaSSIF) or PBS (pH 7.4) was added to each vial to a final volume of 500 μl. One PTFE-sealed stir bar (V&P Scientific) was placed in each vial, which was then sealed with a PTFE / SIL plug (BioTech Solutions). The vials were shaken at 1100 rpm for 2 hours at 25°C. The samples were then filtered through a MultiScreen Solvinert filter plate (Millipore) by vacuum filtration. An aliquot (5 μl) of the filtrate and 5 μl of DMSO were diluted in 50% acetonitrile in water (490 μl) containing an internal standard. The filtrates were analyzed and quantified against standards of known concentration using LC-MS / MS. Solubility values ​​for the test and control compounds were calculated as follows: [Sample] = (area ratio 試料 *INJ VOL STD*DF試料 *[STD]) / (Area ratio STD*INJ VOL 試料 ).

The results demonstrate that certain compounds of the present invention exhibit higher solubility in PBS and / or FaSSIF than Comparative Example 1. Certain compounds of the present invention exhibit solubility in either PBS or FaSSIF, and certain compounds exhibit higher solubility values ​​in both PBS and FaSSIF. Therefore, certain compounds of the present invention can be expected to exhibit improved bioavailability and / or improved systemic exposure than Comparative Example 1, particularly when the compound is administered orally.

[0410] Biological Example 4 - Liver Microsomal and Hepatocyte Intrinsic Clearance Assays (Hepatocyte clearance assay) In vitro clearance studies were performed on primary rat and human hepatocytes (BioIVT). Vials of cryopreserved rat or human hepatocytes were thawed in a 37°C water bath for 2 minutes. Cells were transferred to thawing medium (Williams medium E containing 30% Percoll, 1x GlutaMAX-1, 15 mM HEPES, 5% fetal bovine serum (FBS), 4 μg / ml insulin, and 1 μM dexamethasone), centrifuged at 100g for 10 minutes, and then thawed at 0.5x10 6Hepatocytes were resuspended in culture medium (Leibovitz's L-15 medium) at a concentration of 10 ... Samples (25 μl) were collected at t = 0, 15, 30, 60, 60, and 120 min and mixed with 6 volumes (150 μl) of acetonitrile containing internal standards (100 nM alprazolam, 200 nM caffeine, and 100 nM tolbutamide), vortexed for 5 min, and centrifuged at 3220 g for 45 min. An aliquot (100 μl) of the supernatant was diluted with 100 μl of ultrapure water, and the mixture was used for LC / MS / MS analysis. All incubations were performed in duplicate. Peak areas were determined from extracted ion chromatograms. The slope value k was determined by linear regression of the curve of the natural logarithm of the percentage of parent drug remaining versus incubation time. The in vitro half-life (in vitro t) was determined from the slope value: in vitro t = 0.693 / k. In vitro t (unit: min) and in vitro intrinsic clearance (in vitro CL int , unit: μL / min / 1×10 6 Conversion to saturation (cells) was performed using the following equation (average of duplicate measurements): In vitro CL int =kV / N V = incubation volume (0.2 mL) N = number of hepatocytes per well (0.1 x 10 6 cell).

Reactions were performed in a final volume of 250 μl of preheated (37°C) 100 mM phosphate buffer containing 5 mM MgCl, 0.025 mg / ml alamethicin, and 0.5 mg / ml rat liver microsomes. Where appropriate, NADPH and UDPGA were included at 1 mM and 2 mM, respectively. Reactions were initiated with the addition of 1 μM (final concentration) of test compound. Verapamil was used as a positive control. Solutions were incubated in a 37°C water bath, and aliquots were taken at 0.5, 5, 15, 30, and 60 minutes. The reaction was stopped by the addition of 5 volumes of cold acetonitrile containing internal standards (200 nM caffeine and 100 nM tolbutamide). Samples were centrifuged at 3220 g for 40 minutes. An aliquot of the supernatant was diluted 1:1 in ultrapure water and then used for LC-MS / MS analysis. Peak areas were determined from extracted ion chromatograms. The slope value k was determined by linear regression of the curve of the natural logarithm of the percentage of parent drug remaining versus incubation time. The in vitro half-life (in vitro t1 / 2) was determined from the slope value: in vitro t1 / 2 = 0.693 / k. The in vitro intrinsic clearance (in vitro CL) of in vitro t1 / 2 (min) was int Conversion to RT (units: μL / min / mg protein) was performed using the following equation (average of duplicate measurements): In vitro Clint = (0.693 / t1 / 2) * (volume of incubation (μl) / amount of protein (mg)).
