TECHNICAL FIELD
[0001] The present application relates to a composition for promoting decomposition of a protein aggregate, a pharmaceutical composition for preventing or treating a neurodegenerative disease accompanied by formation of a protein aggregate, and a novel compound or a salt thereof and a method for producing the same. BACKGROUND
[0002] Neurodegenerative diseases typified by Alzheimer's disease and Parkinson's disease are diseases in which nerve cells are gradually destroyed. In the nerve cells that are degenerated, accumulation of aggregates of proteins is generally observed pathologically. Such aggregates of proteins are not observed in brain regions other than the lesion. This suggests that the formation of aggregates of proteins is one of the causes of neurodegenerative diseases, and that a therapeutic drug for neurodegenerative diseases in general can be developed by inhibiting the accumulation of aggregates of proteins.
[0003] In diseases such as Alzheimer's disease (AD), a part of frontotemporal lobar degeneration (FTLD), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and the like, accumulation of aggregates of hyperphosphorylated Tau protein is pathologically confirmed, and is collectively referred to as a Tauopathy. On the other hand, in diseases such as Parkinson's disease (PD), multiple sclerosis (MS), dementia with Lewy bodies (DLB), rapid eye movement sleep behavior disorder (RBD), and the like, alpha synuclein forms aggregates, and is collectively referred to as a synucleinopathy. In addition, TDP-43, which is considered to be the cause of frontotemporal lobar degeneration (FTLD), amyotrophic lateral sclerosis (ALS), and the like, and prion protein (PrP), which is the cause of Creutzfeldt-Jakob disease (CJD), bovine spongiform encephalopathy (BSE), also form intracellular aggregates of diseases. These diseases have in common that, as the disease progresses, the degenerative protein that forms aggregates becomes a template, converts normal proteins into a degenerative form, thereby propagating aggregates between cells, and thereby expanding the lesion area of the disease.
[0004] The protein aggregate is decomposed in the lysosome by aggregate-selective autophagy. The process of recognizing the aggregate and transporting it to the lysosome is particularly called aggregate autophagy. In the aggregate, polyubiquitin chain is attached, and the autophagy receptor recognizes the polyubiquitin chain, whereby the aggregate is enclosed in the autophagosome (refer to Figure 9 ). The present inventors et al. reported that phosphorylation of the serine residue at position 403 (S403) of the most ubiquitous p62 / SQSTM1 protein in the autophagy receptor, thereby binding to the polyubiquitin chain with high affinity, promotes the efficiency of engulfment by the autophagosome (Non-patent Literatures 1, 2).

[0127] The phosphorylation-promoting composition of the present application can promote phosphorylation of the serine at position 403 from the N terminus of the amino acid sequence of human p62 shown in SEQ ID NO: 1. In addition, the phosphorylation-promoting composition of the present application can promote phosphorylation of the serine in the amino acid sequence of p62 of a non-human animal corresponding to the serine at position 403 of SEQ ID NO: 1. The serine of p62 of a non-human animal corresponding to the serine at position 403 of SEQ ID NO: 1 can be determined by aligning the amino acid sequence of SEQ ID NO: 1 with the amino acid sequence of p62 of a non-human animal.
[0128] The serine at position 403 from the N terminus of the amino acid sequence of human p62 shown in SEQ ID NO: 1 can also be referred to as the serine at position 38 from the C terminus of the amino acid sequence of human p62 shown in SEQ ID NO: 1. Therefore, the phosphorylation-promoting composition of the present application can promote phosphorylation of the serine in the amino acid sequence of p62 of a non-human animal corresponding to the serine at position 38 from the C terminus of SEQ ID NO: 1. The serine of p62 of a non-human animal corresponding to the serine at position 38 from the C terminus of SEQ ID NO: 1 can be determined by aligning the amino acid sequence of SEQ ID NO: 1 with the amino acid sequence of p62 of a non-human animal.
[0129] The amino acid sequence of p62 of a non-human animal can be obtained from a publicly known database such as NCBI. For example, in the amino acid sequence of p62 of a mouse (NCBI Reference Sequence: NP_035148.1), phosphorylation of the serine at position 405 from the N terminus, the serine at position 38 from the C terminus is promoted, in the amino acid sequence of p62 of a rat (NCBI Reference Sequence: NP_787037.2), phosphorylation of the serine at position 402 from the N terminus, the serine at position 38 from the C terminus is promoted, in the amino acid sequence of p62 of a cow (NCBI Reference Sequence: NP_788814.1), phosphorylation of the serine at position 403 from the N terminus, the serine at position 38 from the C terminus is promoted, and in the amino acid sequence of p62 of a monkey (NCBI Reference Sequence: NP_001253287.1), phosphorylation of the serine at position 402 from the N terminus, the serine at position 38 from the C terminus is promoted.
[0130] Phosphorylation of the serine at position 403 from the N terminus of the amino acid sequence of human p62 shown in SEQ ID NO: 1 can be confirmed, for example, by extracting proteins from cells contacted with a compound represented by General Formula (I) or a salt thereof and cells not contacted with a compound represented by General Formula (I) or a salt thereof, respectively, and performing Western blotting using an antibody that specifically binds to p62 in which the serine at position 403 is phosphorylated.

[0637] In the test examples below, the compounds produced above (ADI derivatives, NUT compounds) were also used for evaluation.
[0638] [Test Example 1: Evaluation of the amount of intracellular accumulation of S403 phosphorylated p62 based on ADI derivative treatment]
[0639] (1) Experimental method
[0640] Cells used were N2a (derived from mouse neuroblastoma) and HEK293 (derived from human embryonic kidney cells). Cells were seeded in 6-well plates, and the next day various ADI derivatives (1 µM) were added to the culture medium, and incubated for 24 hours. A control group was set up in which no ADI derivative was added. The culture medium used was DMEM (high sugar; WAKO) + 10% FBS (gibco). After 24 hours, after removing the culture medium, cells were washed with PBS, 1 mL of PBS was added, and the cells were detached by pipetting, added to a 1.5 mL tube, and centrifuged at 1200 rpm for 10 seconds, and the cells were recovered. After removing the supernatant, the cells were suspended with 100 µL of PBS, and subjected to ultrasonic disruption (BRANSON, 5W for 10 seconds), mixed with 2x SDS-sample buffer at 1:1, and 20 µL was supplied to SDS-PAGE, and subjected to Western blotting. The primary antibody used was a self-made anti-S403-P-p62 monoclonal antibody (clone #4F6, Matsumoto et al., Mol Cell. 44(2) 279-289, 2011) and an anti-p62 antibody (MBL, PM045).
[0641] (2) Results
[0642] The results are shown in Figure 1 (A) is the results of N2a cells, and (B) is the results of HEK293 cells. In terms of (A) and (B), in the cells treated with the ADI derivative, both the total amount of p62 protein and the accumulation amount of S403-phosphorylated p62 protein increased compared to the control group. From this result, it was found that the ADI derivative has a S403-phosphorylation promoting effect on p62 protein.
[0643] [Experiment Example 2: Study of the mechanism of the phosphorylation promoting effect of the ADI derivative]
[0644] (1) Experimental method
[0645] Cells used were mouse neuroblastoma cells (N2a+RG-p62 cells) that continuously express a mouse p62 protein (RFP-GFP-p62) in which red fluorescent protein (RFP) and green fluorescent protein (GFP) are linked in a straight line. N2a+RG-p62 cells were produced by the following method: a pRFP-GFP-mp62 vector was obtained by introducing GFP-mp62 (Matsumoto et al., Scientific Reports 8(1) 2018) into pRFP-C1-DEST (Matsumoto et al., Human molecular genetics 24(15) 4429-4442, 2015) using a gateway system, and the pRFP-GFP-mp62 vector was introduced into N2a cells using LipofectAmine3000, and a stable expression strain was selected. ADI derivatives used were ADI-14 and ADI-29. N2a+RG-p62 cells were seeded in a 6-well plate, and on the next day were cultured for 24 hours in separate treatment with an ADI derivative (1 µM), co-treatment with an ADI derivative (1 µM) and bafilomycin A (0.5 µM, hereinafter referred to as “BafA”), and co-treatment with an ADI derivative (1 µM) and BX795 (0.5 µM). As controls, an untreated group, a BafA-treated group, and a BX795-treated group were set. After 24 hours, cells were recovered, cell extracts were prepared, and the amount of intracellular accumulation of S403-phosphorylated p62 contained in the extracts was evaluated by Western blotting, in the same manner as in Test Example 1. The same antibodies as in Test Example 1 were used. BafA is a compound that has the effect of inhibiting the breakdown of autophagosomes by lysosomes by inhibiting the fusion of autophagosomes with lysosomes, and BX795 is a compound that has a TBK1 inhibitory effect.
[0646] (2) Results
[0647] The results are shown in Figure 2"endo.p62" indicates an endogenous p62 protein. As in Test Example 1, in the ADI-14-treated group and the ADI-29-treated group, the amount of accumulation of S403-phosphorylated p62 increased. Phosphorylated p62 is continuously decomposed, and thus, in the control group, the ADI-14-treated group, and the ADI-29-treated group, S403-phosphorylated p62 accumulated in the cells by inhibiting decomposition by the addition of BafA. When the TBK1 inhibitor (BX795) was added, S403-phosphorylated p62 did not accumulate in the control group, the ADI-14-treated group, and the ADI-29-treated group. That is, it was shown that the S403-phosphorylation promoting effect of the ADI derivative on p62 was inhibited by the TBK1 inhibitor. Thus, it was indicated that the ADI promotes S403-phosphorylation of p62 by inducing activation of TBK1.
[0648] [Experiment Example 3: Study of genes induced by ADI derivatives]
[0649] (1) Experimental method
[0650] (1-1) Cell test
[0651] N2a cells were seeded in a 6-well plate, and the next day, ADI-14 and ADI-29 were added at a final concentration of 1 µM, respectively, and incubated for 24 hours. After 24 hours, the cells were recovered, and total RNA was extracted using TRI reagent (trade name, Molecular Research Center Inc.), and 2 µg of the RNA was subjected to reverse transcription using PRIME script MAX (TAKARA) to synthesize cDNA, and quantitative PCR was performed using THUNDERBIRD SYBR qPCR Mix (TOYOBO). The genes to be measured were set to Atf3 (Activating transcription factor 3), Ddit3 (DNA damage-inducible transcript 3), Gadd45a (Growth Arrest and DNA Damage-inducible 45), Nfil3 (Nuclear factor, interleukin 3 regulated), Ppp1r15a (Protein phosphatase 1 regulatory subunit 15A), p62 / Sqstm1 (p62 / sequestosome 1), and Trib3 (Tribbles Pseudokinase 3). For the genes to be measured, RNA sequencing (RNA-seq) was performed on ADI-treated N2a cells and untreated N2a cells, and by comprehensive analysis of genes with large differences in expression amounts, genes that were presumed to be increased in expression due to ADI treatment were selected. The expression amount of each gene (mRNA) was calculated as the relative mRNA amount with respect to the control (no ADI derivative treatment) using the ΔΔCt method, with the mRNA expression amount of the Gapdh gene as a reference.
[0652] (1-2) Animal Test
[0653] ADI-14 and ADI-29 dissolved in DMSO were dissolved in olive oil (containing 1% DMSO as a final concentration), and C57BL / 6J mice were forcibly administered orally at 50 µg per day for two weeks. After the end of the administration period, the mice were euthanized, the hippocampus was collected, and total RNA was extracted, cDNA was synthesized, and quantitative PCR was performed in the same manner as in (1) above. The genes to be measured were set to Atf3, Ddit3, Gadd45a, Nfil3, Ppp1r15a, p62 / Sqstm1, and Trib3 of mice. For the expression amount of each gene (mRNA), it was also calculated in the same manner as in (1) above.

[0671] (2) Results
[0672] The results of the cell test are shown in Figure 3 Among all the genes measured, the expression amount was significantly increased by the ADI derivative treatment. The results of the animal test are shown in Figure 4 The expression amounts of Atf3 and Nfil3 of the mRNA adjusted from the hippocampus of the mouse brain were significantly increased by the oral administration of the ADI derivative. According to these results, it was suggested that the ADI derivative promoted aggregate autophagy through selective autophagy induction accompanied by the gene expression of Atf3 and Nfil3.
[0673] [Experiment Example 4: Study of the Aggregate Autophagy Promotion Effect of the ADI Derivative Using a Tau Aggregation Cell Line]
[0674] (1) Experimental Method
[0675] A self-made Tau aggregation cell line (G1F1B, G1E3B) was used. The Tau aggregation cell line (G1F1B, G1E3B) is a cell line in which the GFP-hTau-2N4R-P301L protein forms fibers by introducing a Tau aggregation nucleus into HEK293 cells stably expressing GFP-hTau-2N4R-P301L, and continuously maintains the Tau aggregate by passing the Tau aggregation nucleus to the daughter cell at the time of cell division, and is a cell made from HEK293 cells according to the method for producing a Tau aggregation cell line of N2a cells described in Matsumoto et al. (International Journal of Molecular Sciences 19(5) 2018), and the GFP-hTau-2N4R-P301L is a fusion of GFP at the N terminus of the full-length human Tau protein (2N4R) containing the mutation of FTDP-17 (linked to chromosome 17, familial frontotemporal dementia with parkinsonism), i.e., P301L mutation. The Tau aggregation cell line was inoculated at 1 x 10 5 6 cells / 2 mL per well in a 12-well plate and cultured with DMEM + 10% FBS medium. The next day, ADI-14 was added at a final concentration of 1 µM to 3 wells, and in addition, as a control, DMSO was added to 3 wells, and using IncuCyto ZOOM (ESSEN Bioscience) built into a 5% CO2 incubator, 9 parts of each well were fixedly photographed once an hour, and the aggregate number (A) and cell density (% confluence; B) were measured over time.
[0676] (2) Results
[0677] Figure 5 Images were captured over time, capturing cells at an arbitrary time, designated "time 0," and the same cells (including daughter cells) two days later. In the control group, the number of aggregates increased after two days, while in the ADI-14 group, the number of aggregates did not increase even after two days. This result is believed to indicate that ADI-14 induces autophagy of aggregates, degrading tau aggregates and preventing the transfer of seeds to daughter cells, resulting in cells unable to form new aggregates.
[0678] Figure 6 (A) shows the time-dependent change in the average number of aggregates per hour, approximately one hour after the start of fixed-point observation, with t = 0. Error bars represent the standard error (SEM) of the aggregate counts across three wells. This indicates that the addition of ADI-14 significantly reduced the number of tau aggregates (****; p < 0.0001). Figure 6 (B) shows the average of the three wells, where the cell density was determined by the proportion of cells occupying the visual field, with the total visual field occupied being 100. Error bars represent the standard error (SEM) of the number of aggregates across the three wells. This indicates that the addition of ADI-14 did not inhibit cell proliferation. These results indicate that the reduction in the number of tau aggregates by ADI-14 is not due to inhibition of cell proliferation.
[0679] [Test Example 5: Verification of the Effect of Administration of ADI Derivatives on Neurodegenerative Disease Model Animals Forming Amyloid Protein Aggregates]
[0680] (1) Experimental methods
[0681] (1-1) Preparation of dosing solution
[0682] Dissolve 100 mg of the ADI derivative ADI-29 (mw 489.99) in 2 mL of DMSO (Fujifilm) to prepare a 100 mM stock solution. Store the stock solution at -20°C. Dissolve 10 µL of the stock solution in 1 mL of sterilized olive oil (Fujifilm), stir thoroughly, and incubate at 65°C overnight to prepare a dosing solution (1 mM ADI-29, 0.5 mg / mL) dissolved in olive oil. For each dose solution preparation, prepare 10 tubes of 1 mL of the dosing solution and store at 4°C. Store at room temperature for one week before dosing.
[0683] (1-2) Neurodegenerative Disease Model Animals
[0684] As a model animal of a neurodegenerative disease in which amyloid protein aggregates are formed, PS19 mice (B6; C3-Tg(Prnp-MAPT*P301S)PS19Vle / J, Jackson Laboratory) were used. PS19 mice are Tau protein disease model mice in which a mutant human Tau (MAPT) P301S-1N4R isoform derived from frontotemporal lobar degeneration with Parkinsonism linked to chromosome 17 (FTDP-17) is integrated under the prion promoter, and formation of hyperphosphorylated Tau aggregates in nerve cells and brain atrophy are confirmed at 8 to 10 months of age.
[0685] (1-3) Administration schedule
[0686] ADI-29 was started to be administered to 36-week-old PS19 mice. The above administration solution was administered 100 µL three times a week by force-feeding into the stomach using an oral feeding tube (ADI-29 administration group, n = 8). The administration period was 10 weeks. The control group (n = 7) was orally administered 100 µL of olive oil.
[0687] (1-4) Detection of intracerebral phosphorylated Tau aggregates
[0688] Two days after the final administration, the mice were euthanized, the brains were removed, and fixed by immersion in formalin. Sagittal sections were prepared from the hemispheres of the brains fixed by formalin, and immunostaining was performed with an anti-phosphorylated Tau (S202 / T205) antibody (AT8, Thermo Fisher Scientific) used in the detection of human Tau protein disease pathology in order to confirm Tau aggregates.
[0689] (1-5) Measurement of the thickness of the CA1 nerve cell layer of the hippocampus
[0690] It is known that in PS19 mice, hippocampal atrophy due to nerve cell death of the nerve cell layer of the hippocampus occurs due to accumulation of AT8-positive Tau aggregates. Therefore, in order to measure the thickness of the CA1 nerve cell layer of the hippocampus, a rabbit anti-NeuN monoclonal antibody (abcam ab177487) was used to perform fluorescent immunostaining (Alexa 568) of the NeuN protein specifically expressed in nerve cells, and a KEYENCE integrated microscope (BX-810) was used to take images of the hippocampal region with a 40x objective lens. The width of the CA1 nerve cell layer located above the dentate gyrus of the hippocampus was measured at 5 places per section, and the values for 2 sections per mouse (a total of 10 places per mouse) were analyzed using the statistical analysis software PRISM9.
[0691] (2) Results
[0692] The results of immunostaining brain tissue sections with anti-phospho-Tau antibodies are shown in Figure 7 In the control group, AT8-positive tau was observed in the form of aggregates throughout the brain, including the cerebral cortex, hippocampus, and brainstem. In the hippocampus, in particular, AT8-positive tau was confirmed to accumulate in the neuronal cell bodies of the CA1 region. On the other hand, in the ADI-29-administered group, although AT8-positive tau was detected in parts of the brainstem and hippocampus, almost no AT8-positive tau aggregates were observed that accumulated in neuronal cell bodies, such as those observed in the CA1 region.
[0693] The results of measuring the thickness of the CA1 neuronal layer of the hippocampus are shown in Figure 8 . Figure 8 (A) is an image of brain tissue sections fluorescently immunostained with anti-NeuN monoclonal antibody. Figure 8 (B) is a graph showing the measured values of the width of the CA1 neuron layer (the width between the arrows in (A)). Figure 8 As shown in (A) and (B), atrophy of the CA1 neuronal layer in 46-week-old PS19 mice was significantly suppressed in the ADI-29-administered group. This result demonstrates that ADI-29 inhibits neuronal toxicity caused by mutant tau and has a therapeutic effect in preventing the formation of phosphorylated tau aggregates and neuronal cell death.
[0694] [Test Example 6: Study on the Inhibitory Effect of ADI Derivatives on the Number of Tau Aggregates Using Tau Aggregating Cell Lines]
[0695] (1) Experimental methods
[0696] The Tau-aggregating cell line (G1F1B) used in Experimental Example 4 was used. The Tau-aggregating cell line was cultured at 5×10 4 Cells were seeded at 100 μg / well in a 24-well plate. The next day, 1 mL of culture medium (DMEM + 10% FBS) and an ADI derivative at a final concentration of 1 μM were added. DMSO was added as a control. Using an IncuCyte ZOOM, the number of fluorescently labeled Tau aggregates and cell density (confluence) were measured at nine locations per well per hour using a 20x objective lens. The average of the nine measured values was converted to a relative value, with the number of aggregates at hour 0 set to 1. Nonlinear curve fitting (logistic growth) analysis was performed using PRISM software using the formula Y = YM × Y0 / ((YM - Y0) × exp(-k × x) + Y0), and YM (Ymax: the theoretical multiple of the increase in aggregates) was determined as the parameter. Measurements were performed for 120 hours, but data analysis was performed up to 100 hours, when cell proliferation was maintained and the data were stable.
[0697] The results are shown in Table 1. Relative aggregation inhibitory activity is indicated as +++, +, or ++. The results of two wells for each compound were averaged.
