Abstract
Description
[Background technology]
[0001] The prototype contains chloroquine (CQ) and hydroxychloroquine (HQ). Minoquinoline is a quinone reductase 2 (QR2) inhibitor, which was originally developed to treat It was originally developed to treat atherosclerosis, but has since been used to treat a variety of conditions, particularly autoimmune diseases, such as systemic lupus erythema. It is also effective in treating other indications, including systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). It has been found that. Singer et al., “Update on immune function.” nosuppressive therapy,” Curr. Opin. Rheu matol. 1998, 10:169-173; se of chloroquine and hydroxychloroquine for non-infectious conditions other tha n rheumatoid arthritis or lupus: a cruci al review,” Lupus 1996, 5 Suppl 1:S59-64 In SLE and RA, aminoquinolines are the mainstay of first-line therapy and are used in combination with other drugs. Aminoquinolines are used to treat the signs and symptoms of SLE and RA. Not only does it improve the condition of the blood, but it also has a beneficial effect on lipid metabolism, reducing the incidence of thrombosis. Similar benefits have been observed in patients with inflammatory or erosive osteoarthritis. It has also been shown to be effective when used as adjuvant therapy in graft-versus-host disease, cancer, and HIV. The effectiveness of this treatment has been shown. Savarino et al., “Effects of chloroquine on viral infections: an old drug against today's diseases?” Lancet I nfect. Dis. 2003, 3(11):722-7; Savarino et al., “Risks and benefits of chloroqui ne use in anticancer strategies,” Lancet Oncol. 2006, 7(10):792-3; Sotelo et al. , ”Adding chloroquine to conventional tr eating for glioblastoma multiforme: ar andomized, double-blind, placebo-control led trial,” Ann. Intern. Med. 2006, 144( 5):337-43.
[0002] The potential of chloroquine (CQ) in neuroprotection has been investigated in the past in stroke, excitotoxicity and Although it has been tested in preclinical models of trauma and trauma, the therapeutic mechanisms remain elusive. CQ increased the number of microglia transported to the site of brain injury in a permanent MCA occlusion model. and dramatically limit PMN migration and reduce reactive astrogliosis and angiogenesis This reduces stroke volume by 60%. Giulian et al., "The ole of mononuclear phagocytes in wound h ealing after traumatic injury to adult m ammalian brain,” J. Neurosci. 1989, 9:44 16-4429; Ivanova et al., “Cerebral ische mia enhances polyamine oxidation: identi fication of enzymatically formed 3-amino propanal as an endogenous mediator of ne uronal and glial cell death,” J. Exp. Me d. 1998, 188:327-340. CQ inhibits the microglia response to various stimuli. It also reduces cytokine production by inflammatory bowel disease cells in vitro. Giulian, ”Microglia and the immune pathology of Alzheimer disease,” Am. J. Hum. Genet. 1 999, 65:13-18.
[0003] As some malaria strains are resistant to CQ, derivative compounds are also being investigated. U.S. Patent Application Publication No. 2006 / 0074105 to Are et al. discloses a method for treating malaria and autoimmune diseases. Certain quinoline and quinazoline derivatives are said to be useful in the treatment of autoimmune diseases. The conductor is described.
[0004] CQ and HQ are often used clinically as first-line therapy for autoimmune disorders. However, its effectiveness is limited by serious side effects. The drug is retinal toxic and unless dosing is limited, long-term use can lead to "target maculopathy" and loss of vision. Cardiac toxicity, although rare, can also occur, resulting in conduction disturbances (e.g. This may manifest as either a myocardial infarction (e.g., bundle branch block) and / or cardiomyopathy associated with congestive heart failure. Electron microscopy of cardiac and retinal biopsies after long-term CQ or HQ therapy has shown This directly results in high drug accumulation in endothelial cells (as well as in melanosomes in the retina and skin). Characteristic cytoplasmic inclusions that are believed to be the result of the endothelial cell death were identified. During therapeutic administration, CQ can accumulate at mM concentrations in skin, retina, kidney and liver cells. , plasma concentrations remain <1 μM.
[0005] In particular, further aminoquinoline quinolone derivatives, which also reduce lysosomal storage and reduce toxicity, are There remains a need for the development of nonreductase 2 (QR2) inhibitors. Summary of the Invention

[0088] The invention is explained in more detail in the following non-limiting examples. EXAMPLES
[0089] [Example 1] (Development of non-lysosomotropic aminoquinoline inhibitors of QR2) Chloroquine and hydroxychloroquine are lysosome antagonists that preferentially accumulate in the lysosomes of cells. It is a lysosomotropic drug. For chloroquine, the p-amino acid of the tertiary amine nitrogen The Ka of the quinoline nitrogen is 10.32 and the pKa of the quinoline nitrogen is 7.29. At pH 4-5.5, nearly 100% of chloroquine is doubly protonated, resulting in a 2+ charge. It becomes a strongly hydrophilic membrane impermeant molecule and is thus trapped in acidic organelles. do.
[0090] A quantitative treatment of such trapping phenomena involves the determination of the relative distribution of all forms of the compound at various pH levels. The partitioning properties can be obtained by examining the octanol-water partition coefficient, LogD, of the drug. Compounds with a positive LogD for a given pH are relatively lipophilic and membrane permeable. Compounds with high but negative LogD are hydrophilic and have low membrane permeability.
[0091] Figures 1A-1B show the LogD of chloroquine and QR2I-44. The regions depicted represent the likely range of lysosomal pH encountered in vivo. At lysosomal pH, the LogD of chloroquine is negative, and these molecules at these pHs This reflects accumulated charges and loss of membrane permeability. For this reason, LogD remains positive over the range of lysosomal pH and thus The lipophilicity and therefore membrane permeability of the glycerol derivatives are maintained to a certain degree.
[0092] Lysosomal storage is associated with 4- This is believed to be the primary mechanism responsible for the major toxicity of aminoquinolines (retina, heart). Using gP and LogD calculations and LiPE analysis, the inhibitory properties of QR2 and its lysosomal Candidate compounds were determined with the aim of combining low likelihood of accumulation.
[0093] From these analyses, the compound 7-methoxy-4-(pyridin-3-yl)methylaminoxidase was Nolin (referred to herein as "QR2I-44", "QR2i-44" or "I-44" ) (the structure is shown in Example 3 below) was found. The LogD value of this compound remained positive. and the compounds remain lipophilic (and therefore membrane permeable) at pH 4–5 in the lysosome. As mentioned above, Figures 1A-1B show that chloroquine (Figure 1A) and QR The LogD of 2I-44 (Figure 1B) is shown.
[0094] The 4-aminoquinoline scaffold has been used since the initial discovery of chloroquine and hydroxychloroquine. Although it has been investigated by several groups, this particular compound has not been investigated to date. Previous studies have not demonstrated the efficacy of 7-aminoquinolines for antimalarial activity. The extensive literature already available that considers the necessity of halogen substitution at the 4-aminoxyloxy group has led to the We consciously avoided extending the Norrin scaffold to include compounds with methoxy at the 7-position. It is possible that the structure-activity relationship vity relationships in 4-aminoquinoline a tiplasmodials,” J. Med. Chem. 2002, 45: 3531-3539; Shreekant and Bhimanna, ”4-am inoquinolines: An Overview of Antimalari al Chemotherapy,” Med. Chem. 2016, 6:001 -011.)
[0095] The 7-halo substituted derivatives were initially shown to be more active than the unsubstituted analogues (Fol ey and Tilley, “Quinoline antimalarials: mechanisms of action and resistance prospects for new agents,” Pharmacol. Her. 1998, 79: 55-87). Several other groups have used 7-chloro is indeed essential for the inhibition of B-hematin formation (e.g., Vippagunta e t al., “Structural specificity of chloro quine-hematin binding related to inhibit ion of hematin polymerization and parasi te growth,” J. Med. Chem. 1999, 42: 4630 ), 7-chloro group and NH2 and OCH3 (methoxy), etc. Replacement of the β-hematin group with other electron donor groups inhibits B-hematin formation and therefore antimalarial activity.

It causes damage, induces diffuse axonal injury, and produces measurable vestibular motor deficits and long-term neurological deficits. The TBI model is a single-arm MRI designed to avoid skull fractures. The damage is mainly caused by acceleration / deceleration forces. The therapeutic compound was delivered intraperitoneally 4 hours after TBI and then weekly thereafter for the duration of the experiment. This was terminated after 28 days with assessment of spatial learning and memory.
[0105] Figures 2, 3 and 4 show the therapeutic effect of QR2I-44 and similar inhibitory properties (7- chloro-N-methylquinolin-4-amine), and both are weak QR2 inhibitors. Compound 2 (7-chloro-N-(pyridin-3-yl)quinolin-4-amine) and CQ Treatment with three other 4-aminoquinoline compounds that inhibit QR2, consisting of (chloroquine) The results of the assessment of vestibular motor function after TBI are summarized in Table 1. The subjects were subjected to the rotarod test for 5 consecutive days after TBI, then on the 7th and 28th days. Figure 2A-B shows that after 5 days, locomotion was observed in mice treated with QR2i-44 compared to vehicle. Almost 300% improvement in rotor latency (time to fall off the rotor rod) compared to CQ Figures 3 and 4 show that QR2I-44 is 1 hour away from TBI, showing an improvement of almost 200%. Results: After 1 and 4 weeks, the study produced sustained improvements in vestibular motor function compared to other QR2 inhibitors This indicates that.
[0106] FIG. 5A-B shows a harpoon for testing the ability of a mouse to find a submerged platform. We summarize the results of spatial learning and memory assessment using the mouse water maze 4 weeks after TBI. The subjects were given 4 trials per day for 4 consecutive days (intertrial interval = 30 min). The latency to find was recorded and averaged over four trials per day. Mice were then cultured for 28–31 days after injury. Mice were examined on the day of surgery (n = 11-12 mice per group). Standard control studies were also performed. Figure 5B shows the effect of QR2I-44 on the inflammatory bowel function in animals treated with QR2I-44 compared to vehicle. showed a 30-35% improvement in learning and memory in the control group, and Figure 5A shows that this improvement in function was This indicates that the results are not confounded by differences in motor function (i.e., swimming speed).

A total of 15 mice (postnatal age 10–14 days) were Normal n=3; Vehicle n=6; QR2I-44 n=6. BI and treatment followed the same protocol as for vestibular motor and learning / memory assessment. After fixation, the rats were sacrificed and perfused 6 weeks after TBI. After fixation, the brains were removed from the skull and perfused with 0.5% Pr The tissue was stored in formalin supplemented with oHance to facilitate high-resolution MRI.
[0108] The MRI protocol consisted of: (1) a 3D T1-weighted FLASH® sequence V = 1.8cm x 1.8cm x 1.8cm; matrix = 256 x 256 x 256; solution Image resolution = 70 x 70 x 70 μm / pixel; TE / TR = 6 / 30 ms; average = 16; Lip angle = 34; scan time = 6 hours 33 minutes; (2) 3D DTI-based high resolution Spin echo FOV=1.8cm×1.8cm×1.8cm; matrix=128× 128×128; resolution=141×141×141μm / pixel; TE / TR=25 / 250 ms; diffusion directions = 60; Ao images = 5; B value per direction = 1500 sec / mm 2; scan time = 73 h 30 min. For post-processing, mouse brains were incubated at 4°C for 1 h at 4°C for 1 h at 4°C. Reference templates from the Forest University mouse database were registered. The DTI parameters were recorded using TrackV and segmented using ITK-SNAP. Calculations were performed using IS software.
[0109] Figure 6A-B shows that hippocampal volume loss after TBI was reduced by QR2I-4 compared to vehicle controls. 7A-B show that the fibromyalgia was substantially alleviated in animals receiving 4 treatment. DTI parameters such as diffusion anisotropy (FA), a measure of tract integrity, were significantly improved compared to controls. In large white matter tract regions such as the corpus callosum / external capsule (CC / EC), significant increases were observed after QR2I-44 treatment. It shows that there will be improvements.

After stimulation with A(CpG), microparticles (M This shows the effectiveness of QR2I-44 in reducing the release of phospholipase A (MP). These particles are small membrane-bound vesicles that arise from activated and dead cells. They are in the 0.0 micron size range and contain nuclear, cytoplasmic and membrane components. MPs have diverse biological functions, as shown in ro and in vivo experiments. Its activities may also mediate inflammation, thrombosis, and intercellular communication, among others. MP has been shown to be effective in treating lupus erythematosus in both physiological and pathophysiological settings.

[0113] Drug-like properties, cardiotoxicity, mutagenicity, hepatocyte stability and cytochrome P450 of compound QR2I-44 An initial screen for mAb P450 inhibition and induction was performed. Not a potent inhibitor of the hERG ion channel (IC50>10μM), but an improved It is not mutagenic in the mutagenic assay and is highly soluble in aqueous solution (water solubility >60 μg / ml) and showed high membrane permeability in Caco2 cells (effective permeability >20×10-6c m / sec) and is not a P-glycoprotein substrate or inhibitor (efflux ratio <0.5; 10 μM elacridar-insensitive), low to moderate mouse and human plasma protein binding (Approximately 50-70% binding by ultracentrifugation) and demonstrates adequate mouse and human hepatocyte stability (>90% remaining at 1 hour) and is not an inducer or inhibitor of CYP3A4 or 2D6. , and found it to be likely to be orally bioavailable and CNS penetrant.
[0114] [Example 4] Absorption and brain penetration of QR2i-44 In mice, QR2i-44 was administered intravenously (IV), intraperitoneally (IP) and orally (P All of the administration methods, including those listed below, were found to be sufficiently absorbed and to have brain permeability. Results of PO delivery of 25 mg / kg QR2i-44 in mouse plasma and brain samples Shows.
[0115] [Table 2]
[0116] [Example 5] (Confirmation of binding to QR2 by the crystal structure of QR2i-44) Molecular replacement was used to form a complex with FADH and QR2i-44 at 1.60 Å resolution. We have determined the crystal structure of reduced QR2, which forms the enzyme. We have examined the effect of redox state on the enzyme structure. To clarify the structure of the oxidized complex, we also determined the structure at 1.40 Å. Using the ribosomal protein as a model, the structure was easily phased by molecular replacement. The quaternary structure is similarly consistent with the established constitutive functional homodimer. r).
[0117] The crystal structure indicates that QR2i-44 and related compounds with planar ring structures bind to natural substrates such as cyclic arylsuccinates. It was confirmed that it binds to QR2 and FADH in a manner similar to that of non. Furthermore, the crystal structure QR2i-44 penetrates the substrate-binding site and binds the planar aromatic functional group and the FAD isoalloxane. Its ability to achieve optimal stacking with Sajin gives it an advantage over other QR2 inhibitors. This shows that it is possible.
[0118] [Example 6] (QR2 Inhibition for the Treatment of Mitochondrial Dysfunction) Parkinson's disease (PD) is the most common motor neurodegenerative disorder. There is an unmet medical need for innovative treatments that can prevent or stop cancer treatments. There is a great need for more treatment options that currently do not exist. PD is characterized by progressive neurodegeneration. The clinical symptoms are non-motor features such as motor impairment and cognitive decline. The exact mechanism underlying the pathogenesis of PD is still unclear. Mitochondrial dysfunction is an important factor contributing to the pathogenesis of both sporadic and familial PD. It is known that mitochondrial complex I activity is one of the factors that contribute to PD. Inhibitors of complex I, e.g., mitochondrial toxins, are used to treat the brain and whole body of subjects with Rotenone has been shown to reduce the behavioral and pathological symptoms of PD when administered to rodents and non-human primates. It mimics many of the underlying clinical features and characteristics of PD. Many of the genes reported to increase mitochondrial function were related to the mitochondrial pathway.
[0119] The quinone reductase 2 (QR2) enzyme can contribute to mitochondrial oxidative damage. In vivo inhibition of this enzyme revealed P, which is indicative of mitochondrial dysfunction and oxidative stress. Blockade of QR2 activity has been shown to suppress neurotoxic effects in PD models, and blockade of QR2 activity has been shown to suppress neurotoxic effects in PD models, In the context of neurodegenerative diseases, mitochondrial function can be protected and restored.
[0120] Interestingly, an association between polymorphisms in QR2 and the risk of developing PD in humans was observed. Some of these polymorphisms result in increased QR2 expression, high enzyme activity, and increased expression in the presence of dopamine. It has been shown that increased ROS production occurs (Harada et al., "An ssociation between idiopathic Parkinson' s disease and polymorphisms of phase II detoxification enzymes: glutathione S-tr ansferase M1 and quinone oxidoreductase 1 and 2,” Biochem Biophys Res Commun. 20 01;288(4):887-92; Wang et al. ion of NRH:quinone oxidoreductase 2 gene promoter polymorphism with higher genes expression and increased susceptibility to Parkinson's disease,” J Gerontol A Bi ol Sci Med Sci. 2008;63(2):127-34).
[0121] Consistent with pathological QR2 activity, previous studies have shown that drugs (e.g., chloroquine and Inhibition of QR2 with riboflavin and resveratrol has been shown to be effective in various animal models of neurological injury, including PD. It has been shown to be neuroprotective in mice (Boutin et al., "Qui none Reductase 2 Inhibitor: Main Biochem ical and Cellular Characterization,” Mol Pharmacol. 2019;95(3):269-859-11; Janda et al., “The antidote effect of quinone oxidoreductase 2 inhibitor against para quat-induced toxicity in vitro and in vi vo,” Br J Pharmacol. 2013;168(1):46-59; Janda et al., “Parkinsonian toxin-induce d oxidative stress inhibits basal autoph agy in astrocytes via NQO2 / quinone oxide reductase 2: Implications for neuroprote ction,” Autophagy. 2015;11(7):1063-80). For example, QR2 inhibition abrogates paraquat-induced toxicity associated with PD (Janda et al. (see above). Furthermore, QR2 inhibition inhibits the PD-associated toxin MPP + Induced neurotoxicity (Boutin et al., supra). In summary, PD The role of oxidative stress, mitochondrial dysfunction, QR2 pathophysiology, and QR in The report that 2 inhibition could mediate protection against neurotoxicity by reducing ROS levels suggests that This supports the rationale for developing QR2 inhibitors as a treatment strategy for D (Cassagn es et al., “Oxidative stress and neurode generation: The possible contribution of quinone reductase 2,” Free Radic Biol M ed. 2018;120:56-61).
[0122] Complex I dysfunction, mitochondrial dysfunction and oxidative stress play important roles in the pathogenesis of PD. (Sanders et al., "Oxidative damage" age to macromolecules in human Parkinson disease and the rotenone model,” Free R adic Biol Med. 2013;62:111-20). Rotenone and paraquat, which cause mitochondrial dysfunction and oxidative stress Environmental toxicants are associated with an increased risk of developing human PD (Tanner et al. l., “Rotenone, paraquat, and Parkinson’s disease,” Environ Health Perspect. 2011 ;119(6):866-72). Thus, toxic exposures associated with PD may be involved in mitochondrial dysfunction. A cellular and in vivo model for endogenous dysfunction and oxidative stress This is the method.
[0123] Wild-type HEK293 cells were cultured with QR2 inhibitors (CDL-1, CDL-2 or QR2i- 44) for 1 hour and exposed to menadione or vehicle for 4 hours. The membrane potential was measured.
[0124] Results: As shown in Figure 10, all QR2 inhibitors were tetramethylrhodamine ethyl esters. Detected by Stere (a fluorescent dye sequestered by live and active mitochondria) QR2i-44 was able to prevent the menadione-induced loss of membrane potential, which was previously thought to be caused by menadione. significantly prevented menadione-induced loss of membrane potential and prevented menadione-induced mitochondrial depolarization. I was able to stop it.
