[Experimental Example 1] Evaluation of the Ability to Inhibit SARM1 Enzyme that Triggers Axonal Degeneration (1)
[0235] As described above, it has been reported that SARM1 promotes axonal degeneration through MKK4-JNK as a downstream signaling in a traumatic axonal injury model (Yang et al., Cell 2015, PMID 25594179), and that SARM1 promotes JNK phosphorylation, and as a result, promotes immune responses around injured neurons (Wang et al., Cell Reports 2018, PMID 29669278). In addition, it has been reported that the JNK pathway is required for axonal degeneration, and that this axonal degeneration is delayed upon JNK inhibition (Miller et al., Nature Neuroscience volume 12, pages 387-389(2009); PNAS Dec. 26, 2012, 109 (52) 21199-21200).
[0236] Accordingly, in order to evaluate the axonal degeneration inhibitory effects of the compounds according to the present invention, the abilities of these compounds to inhibit SARM1 enzyme were analyzed. Specifically, whether phosphorylation of JNK protein, a representative sub-regulatory marker of SARM1, decreased, was evaluated by Western blot assay. A method for preparing the protein used in the Western blot assay is as follows. The gastric cancer cell line MKN1 was treated with PBS, harvested, washed with PBS, and then lysed using RIPA buffer as a cell lysis buffer containing each of A4276H, A4510H, A4265, A4275, A4367, A4375, A4376 and A4512 prepared in the Synthesis Examples. The entire cell lysate was fractionated using a centrifuge, and then only the solution containing the protein was extracted. The extracted protein was quantified by the Bradford method. The protein of the same concentration obtained through quantification was separated by SDS-polyacrylamide gel electrophoresis, and then transferred to a PVDF membrane. The membrane to which the protein has been transferred was blocked with a TBS-T (Tris-buffered saline/0.1% Tween-20) solution containing 5% non-fat milk at room temperature for 1 hour in order to reduce non-specific binding, and incubated with a primary antibody (diluted in 5% BSA solution) at 4° C. for 12 hours or more, and then incubated with a secondary antibody (1:5000 dilution) at room temperature for 1 hour. For visualization, an enhanced chemiluminescence system was used. Western blot assay was performed using JNK protein, a representative marker whose phosphorylation is regulated by SARM1, and the housekeeping protein Hsp90 was used for quantitative comparison of expression. The results are shown in
[0237] As shown in
[Experimental Example 2] Evaluation of the Ability to Inhibit SARM1 Enzyme that Triggers Axonal Degeneration (2)
[0238] 24 hours before the experiment, the F11 cell line (a fusion of the mouse neuroblastoma cell line N18TG-2 with embryonic rat dorsal-root ganglion (DRG) neurons) was seeded into 6-well plates at a density of 3×10.sup.5 cell/well. Using Lipofectamine 2000 reagent, each well was transfected with 1 μg of a pCMV-FKBPF36V-TIR vector. The reason for attaching the FKBP domain (FKBPF36V) to the TIR is that the dimerization of the FKBP domain can be artificially induced upon administration of the AP20187 substance, which in turn induces dimerization of and activates the SARM1 TIR domain attached thereto. After 24 hours, each well was pre-treated with each of the compounds according to the present invention at a concentration of 10 μM for 1 hour, and then treated with 500 nM AP20187 for activation of the TIR domain. After 24 hours, each well was washed with cold PBS and then lysed using RIPA buffer. Next, the protein was quantified by the Bradford assay and then sampled using SDS buffer. 10 μg of the sample was loaded on 12% SDS-PAGE gel. The protein-loaded gel was transferred to a PVDF membrane, incubated in a blocking solution (5% skim milk) for 1 hour, and then subjected to an antigen-antibody reaction with a primary antibody (diluted 1:1,000) at 4° C. for 12 hours or more. After unbound antibody was removed by washing three times with 1× TBST for 10 minutes, the gel was subjected to an antigen-antibody reaction with a secondary antibody (diluted 1:3,000) at room temperature for 1 hour. In addition, after unbound antibody was removed by washing three times with 1× TBST for 10 minutes, a color reaction was developed using the ECL solution to visualize the band. The results are shown in

[0241] As shown in
[Experimental Example 4] Preparation of Tadpole Optic Nerve Axotomy Model and Drug Efficacy Experiment (2)
[0242] In order to verify the axon protective effect of the compound according to the present invention in the tadpole optic nerve axotomy model, an experiment was conducted in the same manner as in Experimental Example 3. Specifically, GFP-expressing DNA was delivered into one retina of a Xenopus tropicalis tadpole at stage 27 (before retinal development) by electroporation. At stage 43 (the time when the connection between the retina and the visual center of the brain is finished), axons of the epectroporated retina were axotomized, and the tissue was fixed at 24-hour intervals, followed by extraction of the brain. Next, the ventral midline of the brain was excised and unfolded, and then the GFP signal in the contra-lateral brain hemisphere was imaged with a confocal microscope (LSM700, Carl Zeiss, 20×, z-step 3 μm). Thereby, it was possible to observe retinal ganglion cell axons located along the optic tract extending from the optic chiasm to the optic tectum. A non-axotomized uninterrupted GFP signal could be observed, which was defined as a healthy axon. Axonal degeneration could be quantified because the continuous GFP signal disappeared along the optic tract over time after axotomy. In most cases, compared to normal tissue, about 50% healthy axons, about 10% healthy axons and 0% healthy axons appeared after 24 hours, 48 hours and 72 hours, respectively. The degree of inhibition of axonal degeneration by the drug was evaluated 48 hours after axotomy. As the drug, N-(4-(5-(methylsulfonyl)benzo[d]oxazol-2-yl) benzyl)nicotinamide hydrochloride (A4510H) was used, and as a control, DMSO was used. Treatment with the drug or the control was performed simultaneously with axotomy, and the non-axotomized group was included in each experiment. The percentage of healthy axons in the drug group relative to the control group taken as 100% was calculated and used as the axon survival score (0 to 100%). The results are shown in

[Experimental Example 5] Evaluation of Inhibitory Effect Against Axonal Degeneration Caused by Anticancer Drugs
[0244] The dorsal root ganglias (DRGs) of mouse embryos (1 to 5 days old) were separated into cell units, and then each cell was fluidically divided into the cell body and the axon by culture in a microfluidic device. At this time, only the axon region was treated with each of the compounds (drugs) of Synthesis Examples 1 to 30 according to the present invention, and movement of the treated drug from the axon region to the cell body region was prevented by increasing the amount of the cell body region medium compared to the amount of the axon region medium through application of pressure due to the difference in height between the media. Treatment with the drug was performed 24 hours before treatment with the anticancer drug vincristine or paclitaxel. The experiment was conducted using a total of three experimental groups: a control group (Untreated), a vincristine/paclitaxel-treated group, and a drug-treated group (40 nM vincristine/100 nM paclitaxel+2 μM test drug). 24 hours after drug treatment, fixing with 4% paraformaldehyde (PFA) was performed. Immunocytochemistry (ICC) was performed with acetylation-alpha-tubulin, and axonal degeneration was quantitatively analyzed by imaging the degree of axonal degeneration with a fluorescence microscope.
[0245] As a result, although not shown in the drawings, it could be confirmed that, when treatment with the compound according to the present invention was performed, axonal degeneration was inhibited even when subsequent treatment with an anticancer agent such as vincristine or paclitaxel was performed.
[0246] Thereby, it could be seen that that the compound of the present invention could exhibit the effect of inhibiting axonal degeneration, and could also effectively prevent or treat chemotherapy-induced peripheral neuropathy (CIPN) by protecting axons from injury caused by anticancer drugs.
[0247] Although the present invention has been described in detail with reference to the specific features, it will be apparent to those skilled in the art that this description is only of a preferred embodiment thereof, and does not limit the scope of the present invention. Thus, the substantial scope of the present invention will be defined by the appended claims and equivalents thereto.
INDUSTRIAL APPLICABILITY
[0248] The present invention is directed to a composition capable of preventing or inhibiting axonal degeneration and effectively preventing, ameliorating or treating various neurological diseases caused by axonal degeneration.
