Description

Technical Field

[0001] The present invention relates to an acetylcholine receptor inhibitory peptide and uses thereof. Background Art

[0002] Acetylcholine is a chemical substance present in animal nerve tissue, which is secreted from nerve endings and plays a role in transmitting nerve stimulation to muscles. As a transmitter secreted from nerve endings, acetylcholine is known in motor nerves and parasympathetic nerves, and adrenaline is known in sympathetic nerves. When acetylcholine is secreted, it exhibits physiological effects such as lowering blood pressure, inhibiting heart rate, contracting intestines, and contracting skeletal muscles. In order to make muscles contract, nerves send contraction commands to muscles, thereby causing muscles to contract. This command causes nerves to secrete acetylcholine at the part where nerves and muscles meet (neuromuscular junction), and this substance binds to the acetylcholine receptors of muscles, thereby causing muscles to contract (Vincent, A., 1985; Lindstrom, JM, et al., 1976). Blocking the acetylcholine receptors at the ends of the skeletal muscles that control the thigh will cause muscle movement paralysis, and blocking the acetylcholine receptors in the smooth muscles and myocardium responsible for breathing or cardiac movement will cause respiratory and cardiac movement paralysis.

[0003] Acetylcholine receptors are divided into muscarinic acetylcholine receptors (mAchR) and nicotinic acetylcholine receptors (nAchR). Muscarinic acetylcholine receptors are a type of G protein-coupled receptor that can be activated by muscarine and activate different signaling mechanisms depending on the subtype. Muscarinic acetylcholine receptors are distributed throughout the body, including the central nervous system and peripheral organs, and mainly play a role in mediating the physiological effects of acetylcholine secreted by postganglionic fibers of the parasympathetic nervous system.

[0004] The nicotinic acetylcholine receptor is a receptor that mimics the pharmacological effects of nicotine and is an ion channel manipulated by neurotransmitters. It is a non-selective cation channel that regulates electronic signaling between nerve cells and muscle cells by opening and closing ion channels and non-selectively passing ions such as sodium, potassium, and calcium. Nicotinic acetylcholine receptors can be divided into muscle type and neuronal type according to the site of expression. Muscle type nicotinic acetylcholine receptors are expressed at the neuromuscular junction where motor neurons and skeletal muscles intersect. Acetylcholine secreted by motor neurons participates in inducing the end plate potential (EPP) of skeletal muscle cell membranes. On the other hand, neuronal nicotinic acetylcholine receptors are expressed in peripheral ganglia of the autonomic nervous system (ANS) and participate in the excitation of postganglionic fibers by acetylcholine secreted by preganglionic fibers.

[0005] Drugs that interfere with or inhibit acetylcholine activity or mimic behavior are very useful. Acetylcholine receptor agonists are used to treat myasthenia gravis and Alzheimer's disease. Myasthenia gravis is an autoimmune disease that occurs when the body produces antibodies against nicotinic acetylcholine receptors and inhibits normal acetylcholine signaling. Myasthenia gravis can be treated by using acetylcholine esterase (AChE) inhibitors, which increase the time that acetylcholine interacts with each receptor before it becomes inactive in the synaptic cleft between nerves and muscles.

[0006] In addition, when the secretion of acetylcholine is inhibited, muscle contraction is inhibited and the muscles are paralyzed, thereby smoothing wrinkles. Botulinum toxin uses this principle. Botulinum toxin prevents the release of acetylcholine, which is an essential substance for muscle contraction, from the motor nerve endings. As a result, the muscles become unable to move, and the wrinkles caused by the muscles disappear. Since the muscle relaxant effect of botulinum toxin gradually disappears after 3 to 6 weeks, repeated administration is required.

[0007] Therefore, the present inventors screened and obtained peptides with high binding affinity to acetylcholine receptors during the process of studying acetylcholine receptor binding peptides, confirmed that these peptides bind to acetylcholine receptors and prevent acetylcholine from binding, thereby preventing the action of acetylcholine receptors, and completed the present invention.

[0008] In addition, the specified arrangement order of specific amino acids that are key in the above-screened peptides binding to the acetylcholine receptor and inhibiting its action was confirmed, and the peptide library expressed by the specific molecular formula was confirmed to bind to the acetylcholine receptor as a whole and was able to inhibit its action, thereby completing the present invention.

[0009] In Korean Patent No. 1216008, which is the prior art, peptides that bind to acetylcholine receptors selected using bio-panning are described, but peptides and libraries containing the amino acid sequence of the present invention are not described. In addition, Korean Patent No. 2018-0028748 discloses a neurotransmitter release-controlling peptide containing acetylcholine and its anti-wrinkle effect, but does not describe the acetylcholine receptor binding ability of the peptide containing the amino acid sequence of the present invention and the acetylcholine receptor action inhibitory effect achieved thereby. Korean Patent No. 2014-0139010 discloses a peptide that promotes transdermal penetration, but the composition is different from the peptide of the present invention that achieves an inhibitory effect by binding to the acetylcholine receptor.

[0100] Fig.10 The results show the inhibitory effect of AchR when treated with different concentrations of palmitoyl-S peptide-2 compared with S peptide-2, Synake, and Bungarotoxin. Due to the increased binding force of Pal-S peptide-2, the inhibitory ability is also increased by about 10 times compared with S peptide-2.

[0102] Fig.12 The results of confirming the binding ability of multiple peptides to AchR by the same method as the surface plasmon resonance analysis method are as follows. The multiple peptides are peptides in which S peptide-2-ND3 is used as the wild type and K in the amino acid sequence is replaced by R, and R is replaced by K or N. It was confirmed that the activity was maintained when substituted with K or R, but the activity was significantly reduced when substituted with N.

[0130] Hereinafter, the preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the embodiments described herein, and may also be embodied in other forms. Instead, this is provided to make the contents described herein more thorough and complete, and to fully convey the ideas of the present invention to those skilled in the art.

[0131] <Example 1. Screening of acetylcholine receptor binding peptides by biopanning>

[0132] The inventors of the present invention produced random recombinant phages by random peptide library DNA preparation and transformation according to the method described in the prior patent (Korean Patent No. 10-1971092), and screened acetylcholine receptor (AchR) binding peptides by biopanning. At this time, AchR specific peptides were selected from the 4th and 5th biopanning input phages with high binding force and specificity to AchR, and the sequence analysis results thereof were applied to Table 1.

[0133] [Table 1]

[0134]

[0135]

[0136] <Example 2. Confirmation of the Acetylcholine Receptor Binding Ability of Peptides>

[0137] The S-peptides 1 to 11 selected in Example 1 were synthesized, and their binding abilities to AchR were compared using a surface plasmon resonance (SPR) analyzer (Biacore 3000, Biacore A, Sweden).

[0138] In the CM5 chip, which is a biosensor chip for surface plasmon resonance analysis, acetylcholine receptor protein was immobilized with EDC / NHS, and the analysis was performed under the conditions of 20mM Tris (pH 7.0) running buffer, 30μl / min, and 10μM peptide (S peptide-1 to 11) concentration for up to 500 seconds to observe association and dissociation. Figure 3 At this time, Synake, a peptide known to reduce wrinkles by binding to AchR, was used as a positive control group.

[0139] like Figure 1 As shown, it was confirmed that S-peptides 1, 2, 4, and 10 have higher binding affinity to AchR than synakes known to bind to AchR.

[0140] <Example 3. Confirmation of the inhibitory effect of peptide on acetylcholine receptor>

[0141] In order to confirm the AchR action inhibitory effect of the peptide with high binding affinity to the acetylcholine receptor in Example 2, TE671 cells overexpressing AchR were used.

[0142] TE671 cells were cultured for 4 days in DMEM medium containing 10% fetal bovine serum (FBS) and 1% penicillin / streptomycin. The cultured cells were treated with trypsin to remove them and then planted in a 12-well cell culture plate with an 18 mm cover glass. Each well was inoculated with 2×1 4 cells and cultured for 4 days. The coverslip with cells was transferred to a new 12-well plate, and 997μl of Hanks' balanced salt solution (HBSS) and 3μl of Fura-2-AM (intracellular calcium ion marker) were added, and cultured in a cell culture incubator at 37°C and 5% CO2 for 15 minutes. After that, it was washed 3 to 4 times with HBSS buffer to remove the residual Fura-2-AM, and then 1ml of HBSS buffer was added. After the coverslip with cells was inserted into the sample chamber for microscope observation and 500μl of HBSS buffer was added, the peptide selected in the above Example 2-3 was added to a concentration of 0.5μM, 5μM or 50μM, and then left for about 3 minutes to allow it to bind to AchR. After that, 125 μM nicotine or 1 μM acetylcholine was added, and the fluorescence intensity of Fura-2 in the cells was detected to confirm the effect of AchR. Synake and bungarotoxin were used as positive control groups. Figure 2 Shown in.

[0143] like Figure 2 As shown, in the case of treating acetylcholine (A to C), it was confirmed that S-peptide-1 showed a 5% inhibitory effect on the AchR action at a concentration of 0.5 μM, 90% at a concentration of 5 μM, and 100% at a concentration of 50 μM, S-peptide-2 showed a 90% inhibitory effect on the AchR action at a concentration of 0.5 μM, and 100% inhibitory effect at a concentration of more than 5 μM, and S-peptide-4 and S-peptide-10 showed 17% and 47% inhibitory effects on the AchR action at a concentration of 50 μM, respectively. In addition, in the case of treating nicotine (D), it was confirmed that S-peptide-1 and S-peptide-2 had a superior inhibitory effect on the action of nicotine on the acetylcholine receptor compared to Synake.

[0144] This shows that S-peptide-1 and S-peptide-2 have excellent AchR action inhibitory effects, and in particular, S-peptide-2 has the highest binding affinity to AchR and thus has the most excellent AchR action inhibitory effect.

[0145] <Example 4. Synake, S-peptide-1, S-peptide-2 cytotoxicity detection>

[0146] To evaluate the toxicity of S-peptide-1 and S-peptide-2, WST assay was performed in TE671 cells. Figure 3 Shown in.

[0147] like Figure 3 As shown, it was confirmed that S-peptide-1, S-peptide-2 and Synake showed no toxicity at a treatment concentration of 100 M.

[0148] <Example 5. Confirmation of the binding ability of S-peptide-2 peptide with the highest binding ability to acetylcholine receptor>

[0149] In order to confirm the binding ability of S-peptide-2 with the highest binding ability to AchR in Example 2, the dissociation constant (Kd) was analyzed by the same method using the surface plasmon resonance analyzer of Example 2. The result was Figure 4 At this time, the concentration of S peptide-2 was treated at 0.12 to 1 μM, Synake was treated as a positive control, and the dissociation constants were compared.

[0150] like Figure 4 As shown, it was confirmed that the association curve rose sharply when S-peptide-2 was allowed to flow, and the association curve rose depending on the treatment concentration of S-peptide-2. After all the S-peptide-2 was allowed to flow, the rising association curve did not fall in the process of adding only the running buffer for dissociation, which shows that S-peptide-2 and AchR are continuously bound.

[0151] In addition, the Kd value of S-peptide-2 for AchR was analyzed and found to be 1.2 μM. By comparing it with 2300 μM of Synake, it was confirmed that the binding force of S-peptide-2 to AchR was about 2000 times higher than that of Synake.

[0152] <Example 6. Confirmation of important sequence sites in peptides for binding to acetylcholine receptors>

[0153] Example 6-1. Confirmation of binding ability to acetylcholine receptor by stepwise removal of terminal amino acids

[0154] In order to identify the peptide site that plays an important role in binding to AchR, the peptide was modified based on the amino acid sequence of S peptide-2 determined in the above Example 6, and the modified peptide was placed on the surface plasmon resonance analyzer in the above Example 2 to confirm their binding ability to AchR.

[0155] Based on the amino acid sequence of the above-mentioned S peptide-2, the amino acid sequence of the N-terminal or C-terminal of the peptide was gradually removed and the peptides shown in Table 2 below were synthesized. The binding ability of the synthesized peptides to AchR was compared. The results were as follows: Figure 5 Shown in.

[0156] [Table 2]

[0157] Peptide name Amino acid sequence S-peptide-2 WTWKGRKSLLR S-peptide-2-ND1 TWKGRKSLLR S-peptide-2-ND2 WKGRKSLLR S-peptide-2-ND3 KGRKSLLR S-peptide-2-ND4 GRKSLLR S-peptide-2-ND5 RKSLLR S-peptide-2-CD1 WTWKGRKSLL S-peptide-2-CD2 WTWKGRKSL S-peptide-2-CD3 WTWKGRKS S-peptide-2-CD4 WTWKGRK S-peptide-2-CD5 WTWKGR

[0158] like Figure 5 As shown, it was confirmed that when the N-terminal amino acid sequence of S-peptide-2 was deleted step by step (A), the binding ability of S-peptide-2-ND1 to S-peptide-2-ND3 to AchR was reduced by 50% compared with S-peptide-2, but the binding to AchR was still maintained, while the binding ability of S-peptide-2-ND4 to S-peptide-2-ND5 was significantly reduced. In addition, it was confirmed that when the C-terminal amino acid sequence of S-peptide-2 was removed step by step (B), the binding of S-peptide-2-CD1 to S-peptide-2-CD5 with the C-terminal R (arg) removed to AchR was sharply reduced.

[0159] Thus, it was found that the 4th K (Lys) and the 11th R (arg) of the amino acid sequence of S-peptide-2 that binds to AchR are important sites for binding to AchR.

[0160] Example 6-2. Confirmation of binding ability of modified peptides to acetylcholine receptors

[0161] Among the modified peptides of S-peptide-2 confirmed in Example 6-1 above, S-peptide-2-ND3, which was confirmed to be the minimum sequence required for binding to AchR, and S-peptide-2-ND5, which is smaller than S-peptide-2-ND3, were used and applied to the surface plasmon resonance analyzer of Example 2 above to confirm their binding ability to AchR. The results are as follows: Figure 6 shown.

[0162] like Figure 6 As shown, in the case of (A) S-peptide-2-ND3, it was confirmed that the binding force to AchR was high even at low concentrations compared to (B) peptide-2-ND5. The dissociation constant was confirmed to be 3.1 μM for S-peptide-2-ND3 and 57 μM for S-peptide-2-ND5, indicating that the binding force of S-peptide-2-ND3 to AchR was significantly better than that of S-peptide-2-ND5 to AchR.

[0163] It was found that there was no significant difference in the binding ability of 11-mer S-peptide-2 and 8-mer S-peptide-2-ND3 to Ach, while the binding of hexamer (6-mer) S-peptide-2-ND5 to Ach was significantly reduced. In addition, from the above results, it can be confirmed that the three amino acids at the N-terminus of S-peptide-2 do not have much effect on the binding ability to AchR.

[0164] <Example 7. Confirmation of important positions in peptides for binding to acetylcholine receptors using alanine scanning>

[0165] Among the peptides confirmed in the above Example 6, S-peptide-2-ND3 and S-peptide-1-ND3 (KGKGTLNR) in which the three N-terminal amino acids of S-peptide-1 having a high amino acid sequence similarity to S-peptide-2 were removed were used to confirm important sites in the sequence of each peptide and alanine scanning was performed.

[0166] S-peptide-1-ND3 and S-peptide-2-ND3 were used as wild-type peptides, and the amino acid sequences of the peptides in Table 3 were substituted with alanine (alanine, Ala, A) in sequence, and their binding ability to AchR was compared in the same manner as the surface plasmon resonance analysis in Example 2. At this time, the concentration of each peptide was 20 μM. Figure 7 Shown in.

[0167] [Table 3]

[0169] like Figure 7 As shown, it was confirmed that when the 1st K, 3rd K and 8th R of S-peptide-1-ND3 were substituted with A, the binding ability to AchR decreased (A), and when the 1st K, 3rd R, 4th K and 8th R of S-peptide-2-ND3 were substituted with A, the binding ability to AchR decreased. From this, it can be seen that the K and R parts of S-peptide-1-ND3 and S-peptide-2-ND3 are important sites for binding to AchR.

[0170] <Example 8. Binding ability of peptide-modified S-peptide-2 bound to fatty acid derivatives to acetylcholine receptors Confirm >

[0171] Based on the modification of peptides capable of binding to AchR, changes in their binding ability to AchR were confirmed. Specifically, the peptide (palmitoyl-S peptide-2) with the highest binding ability to AchR among the peptides determined in Example 2 was used, and its binding ability to AchR was confirmed by the same method as the surface plasmon resonance analysis method in Example 2. The results are as follows: Figure 8 At this time, the binding ability of S peptide-2 to AchR was used as a control group.

[0172] like Figure 8 As shown in Figure 2, it was confirmed that palmitoyl-S peptide-2 has a stronger binding affinity to AchR than S peptide-2. The reason is that Fig. 9 As shown, a micelle structure is formed in which the fat-soluble palmitoyl is aggregated inward and the water-soluble S-peptide-2 is exposed outward, thereby having an affinity effect for binding to various sites of AchR.

[0173] <Example 9. Confirmation of the inhibitory effect of palmitoyl-S peptide-2 on acetylcholine receptors>

[0174] The AchR inhibitory effect of palmitoyl-S peptide-2, which was confirmed to have excellent binding ability to AchR in Example 8, was confirmed. At this time, the AchR inhibitory effect was confirmed in the same manner as in Example 3, and palmitoyl-S peptide-2 was treated at different concentrations. In order to compare the AchR inhibitory effect, S peptide-2, Synake, and Bungarotoxin were treated at different concentrations as a control group. The results are shown in FIG. Fig.10 shown.

[0175] like Fig.10 As shown, it can be seen that the inhibitory effect of palmitoyl-S peptide-2 on AchR is better than that of S peptide-2. More specifically, the IC50 values ​​of each peptide for AchR were observed, and Synake was 75μM, S peptide-2 was 750nM, palmitoyl-S peptide-2 was 75nM, and Bungarus toxin was 7.5nM, confirming that the inhibitory effect of Pal-Espep-2 on AchR was 10 times stronger than that of S peptide-2.

[0176] <Example 10. Palmitoyl-S peptide-2 cytotoxicity assay>

[0177] To evaluate the toxicity of palmitoyl-S peptide-2, WST analysis was performed in TE671 cells. Fig.11 Shown in.

[0178] like Fig.11 As shown, it was confirmed that palmitoyl-S peptide-2 did not show cytotoxicity even when treated at a concentration of 10 μM.

[0179] <Example 11. Binding ability to AchR by substitution of K and R amino acids in the amino acid sequence of S-peptide-2-ND3 Change Confirmation>

[0180] In Example 7, it was examined whether the binding ability to AchR was changed when K was substituted by R and R was substituted by K or N in the amino acids K and R of S-peptide-2-ND3 confirmed to be important sites for binding to AchR.

[0181] S-peptide-2-ND3 was used as the wild type, and the peptides shown in Table 4 below were synthesized, wherein K in the amino acid sequence of S-peptide-2-ND3 was replaced by R, and R was replaced by K or N, and the binding to AchR was confirmed by the same method as the surface plasmon resonance analysis method in Example 2. At this time, the concentration of each peptide was treated at 20 μM. The results are as follows: Fig.12 shown.

[0182] [Table 4]

[0183]

[0184]

[0185] like Fig.12 As shown in the figure, the binding force to AchR increased in the case of the peptide in which K of S-peptide-2-ND3 was replaced by R, and the binding force to AchR slightly decreased in the case of the peptide in which R was replaced by K, but no significant difference was confirmed. On the contrary, it was confirmed that the binding force to AchR was significantly reduced in the case of the peptide in which R was replaced by N. From this, it can be seen that even if the K and R parts in the amino acid of S-peptide-2-ND3 are replaced with each other, the binding to AchR does not change, but when R is replaced by N, the binding force to AchR is lost.

[0186] <Example 12. Preparation of a peptide library for screening optimized peptides with improved binding ability to acetylcholine receptors>

[0187] Example 12-1. Preparation and transformation of random peptide library DNA

[0188] Based on the results confirmed in Examples 6, 7, and 11 above, the S-peptide-2-ND3 peptide sequence was modified to prepare the following random peptide libraries: octamer (8mer), (K / R)X(K / R)(K / R)XXX(K / R); nonamer (9mer), X(K / R)X(K / R)(K / R)XXX(K / R), (K / R)X(K / R)(K / R)XXX(K / R)X; decamer (10mer), XX(K / R)X(K / R)(K / R)XXX(K / R), (K / R)X(K / R)(K / R)XXX(K / R)XX, XX(K / R)X(K / R)(K / R)XXX(K / R), (K / R)X(K / R)(K / R)XXX(K / R)XXX, XX(K / R)X(K / R)(K / R)XXX(K / R)X; 12mer, X(K / R)X(K / R)(K / R)XXX(K / R)XXX, XX(K / R)X(K / R)(K / R)XXX(K / R)XX, XXX(K / R)X(K / R)(K / R)XXX(K / R)X; 13mer, XX(K / R)X(K / R)(K / R)XXX(K / R)X XX, XXX(K / R)X(K / R)(K / R)XXX(K / R)XX; 14mer, XXX(K / R)X(K / R)(K / R)XXX(K / R)XXX; and 18mer, XXXXX(K / R)X(K / R)(K / R)XXX(K / R)XXXXX [(K / R) is either K or R, X is a random amino acid], and their acetylcholine receptor inhibitory effects were confirmed. It was confirmed that the binding ability of the peptides in the above random library to the acetylcholine receptor is similar to or better than that of S peptide-2 as a whole.

[0189] Hereinafter, an example of preparing a random peptide library as a representative peptide sequence with particularly excellent binding ability to the acetylcholine receptor and confirming the acetylcholine receptor inhibitory effect is described. The above-mentioned representative peptide sequences with particularly excellent binding ability to the acetylcholine receptor are octamer (8mer), (K / R)X(K / R)(K / R)XXX(K / R); 11mer (11mer), XXX(K / R)X(K / R)(K / R)XXX(K / R); 14mer (14mer), XXX(K / R)X(K / R)(K / R)XXX(K / R)XXX; and 18mer (18mer), XXXXX(K / R)X(K / R)(K / R)XXX(K / R)XXXXX [(K / R) is one of K or R, and X is a random amino acid].

[0190] To prepare peptide libraries of octamer (8mer), (K / R)X(K / R)(K / R)XXX(K / R); 11mer (11mer), XXX(K / R)X(K / R)(K / R)XXX(K / R); 14mer (14mer), XXX(K / R)X(K / R)(K / R)XXX(K / R)XXX; and 18mer (18mer), XXXXX(K / R)X(K / R)(K / R)XXX(K / R)XXXXX [(K / R) is either K or R, and X is a random amino acid], the DNA library shown in Table 5 below was synthesized (BIONEER, Korea). Thereafter, the DNA library synthesized in Table 5 was used as a template and PCR was performed using two single-stranded primers (TTCTATGCGGCCCAG, AACAGTTCTGCGGC) to amplify double-stranded insert DNA (insertDNA). The amplified insert DNA and pIGT (a phagemid vector) were treated with restriction enzymes Sfi I and Not I, and each DNA was purified. After the purified insert DNA and pIGT were ligated using T4 DNA ligase, the precipitate obtained by ethanol precipitation was dissolved in TE (Tris-EDTA) buffer to prepare a random peptide library DNA.

[0191] The prepared random peptide library DNA is placed in competent cells for mixing, and then transformed by electroporation. The transformed cells are placed in LB (luria bertani) liquid culture medium containing 20mM glucose, and transferred to a test tube, and cultured at 200rpm for 1 hour at 37°C. The cultured cells are placed in LB liquid culture medium containing 20mM glucose and 50μg / ml ampicillin, and cultured at 30°C for 1 day. After one day of culture, the supernatant is removed by centrifugation at 4000×g for 20min at 4°C to obtain precipitated cells. After the obtained cells are resuspended in LB liquid culture medium, glycerol is added to make the final concentration above 20%, and stored at -80°C to obtain a random peptide library.

[0192] [Table 5]

[0193]

[0194] Example 12-2. Production of optimized peptide recombinant phage

[0195] The random peptide library obtained in Example 12-1 was added to SB liquid culture medium (3% tryptone, 2% yeast extract, 1% MOPS free acid, 2% glucose), cultured at 37°C and 200 rpm for 20 minutes, and then 1×10 10 pfu helper phage and ampicillin to a final concentration of 50 μg / ml, and cultured again under the same conditions for 1 hour. The culture was transferred to SB liquid medium containing 50 μg / ml ampicillin and 10 μg / ml kanamycin and cultured under the same conditions for 16 hours to produce random peptide recombinant phage.

[0196] The produced random peptide recombinant phage was centrifuged at 5000 rpm for 10 minutes at 4°C to obtain a supernatant, and polyethylene glycol (PEG) / NaCl (20% PEG, 15% NaCl) was mixed in the supernatant at a ratio of 5:1 [v:v]. After being placed on ice for 1 hour, the supernatant was centrifuged at 13000 rpm for 20 minutes at 4°C, the supernatant was removed, and the precipitate was suspended with 1 ml of phosphate buffered saline (PBS), thereby obtaining random peptide recombinant phage.

[0197] <Example 13. Screening of optimized peptides with improved binding ability to acetylcholine receptors>

[0198] Example 13-1. Biopanning method

[0199] The process of treating the fixed antigen with a phage library expressing antibodies on the surface to select candidate antibodies that bind to the antigen is called biopanning, which includes three steps: bind / wash / elution. During the washing process, phages with antibodies with weak binding are removed, resulting in only phages expressing antibodies with high binding. By repeating this process 3 to 4 times, candidate antibodies with excellent antigen binding and specificity can be discovered. Therefore, biopanning is used to screen acetylcholine receptor binding peptides with excellent binding and specificity to the acetylcholine receptor of the present invention.

[0200] 10 μg / ml AchRα1 was added to 8 wells of a 96-well plate, 50 μl per well, and incubated overnight at 4°C. The next day, after washing once with 200 μl of Tris (20 mM pH7), 200 μl of 2% bovine serum albumin (BSA) was added, and blocking was performed at room temperature for 2 hours. The solution was discarded, and the plate was washed 3 times with 200 μl of Tris (20 mM pH7). 400 μl of random peptide recombinant phage (input phage) resuspended in PBS of Example 13-2 above was mixed with 400 μl of 2% BSA, and 100 μl was added to each well, and placed at 30°C for 1 hour. After removing all the solution in the wells and washing three times with Tris (20 mM pH 7), 100 μl of 0.2 M glycine (pH 2.2) was added to each well to elute the phages for 20 minutes, and then all were collected in an EP tube and neutralized by adding 200 μl of 1 M Tris (pH 9.0) (output phage).

[0201] To repeat the biopanning, 500 μl of the eluted phage was mixed with 5 ml of E. coli and incubated at 37°C, 200 rpm for 30 min, and then 1 × 10 10 pfu of helper phage and ampicillin to a final concentration of 50 μg / ml, and further cultured for 30 minutes. The culture medium was transferred to SB liquid medium containing 50 μg / ml ampicillin and 10 μg / ml kanamycin, and cultured overnight under the same conditions to regenerate the random peptide recombinant phage. The regenerated random peptide recombinant phage was centrifuged at 5000 rpm for 10 minutes at 4°C to obtain a supernatant, PEG / NaCl was mixed in the supernatant at 5:1 [v:v], and placed on ice for 1 hour, then centrifuged at 13000 rpm for 20 minutes at 4°C to remove the supernatant, and the precipitate was resuspended with 1 ml of phosphate buffered saline (PBS) for secondary bio-selection.

[0202] For each round of bio-panning, random recombinant phages were regenerated and bio-panned in the same manner as described above. At this time, the number of washes with Tris (20 mM pH 7) was set to 3 or 6 times in the bio-panning step, and AchR was bio-panned 5 times.

[0203] To measure the number of input phage and output phage in each round of bio-panning, they were mixed with E. coli with an absorbance of 0.7 at 600 nm (OD600=0.7) and plated on agar plates containing ampicillin. The results are shown in Tables 6 to 9 below.

[0213] Example 13-2. ELISA using random peptide library input recombinant phage (enyzme-linked immunosorbent assay, ELISA) method

[0214] ELISA was performed for streptavidin and AchR using the input phage from each biopanning in Example 13-1 above.

[0215] In a 96-well ELISA plate, 50 μl of 10 μg / ml AchR or streptavidin was added to each well, incubated overnight at 4°C, washed 3 times with Tris (20 mM pH 7) the next day, 2% BSA diluted with PBS was added and blocked for 2 hours at room temperature, all the solution was discarded and washed 3 times with Tris (20 mM pH 7). 800 μl of the first, second, third, fourth and fifth input phages in Tables 6 to 9 of Example 13-1 were mixed with 200 μl of 10% BSA, 100 μl was added to each well, and placed at 30°C for 1 hour. After removing all the solution in the wells, wash with Tris (20mM pH7) 3 times, then add 100μl of HRP (horseradish peroxidase)-conjugated anti-M13 antibody (HRP-conjugated anti-M13 Ab, GE Healthcare) diluted 1:1000 to each well and react at 30°C for 1 hour. After that, wash with Tris (20mM pH7) 3 times, add 100μl of tetramethylbenzidine (TMB) (HRP substrate) solution to each well to induce color reaction, then add 100μl of 1M HCl to stop the reaction, and measure the absorbance at 450nm (OD450). The results are as follows: Fig.13 shown.

[0216] like Fig.13 As shown, the 8mer, 11mer and 14mer random peptide libraries obtained from the bio-panning input phage showed very high binding specificity to AchR as a whole compared to streptavidin. The 1st, 3rd, 4th and 8th amino acids of the 8mer were fixed to lysine (K) or arginine (R), while the 2nd, 5th, 6th and 7th amino acids were formed to any amino acid, that is, the polypeptide library expressed by the general formula: (K or R)-X-(K or R)-(K or R)-XXX-(K or R) was able to bind to AchR in a highly specific manner as a whole, which was independent of the types of the 2nd, 5th, 6th and 7th amino acids (X).

[0217] Similarly, in 11mer, the polypeptide library expressed by the general formula: XXX-(K or R)-X-(K or R)-(K or R)-XXX-(K or R), regardless of the type of any amino acid (amino acids at positions 1, 2, 3, 5, 8, 9 and 10) represented by X, is generally able to bind with high specificity to AchR when the amino acids at positions 4, 6, 7 and 11 are lysine (K) or arginine (R).

[0218] Similarly, in 14mer, the polypeptide library expressed by the general formula: XXX-(K or R)-X-(K or R)-(K or R)-XXX-(K or R)-XXX, regardless of the type of any amino acid represented by X (amino acids at positions 1, 2, 3, 5, 8, 9, 10, 12, 13 and 14), when the amino acids at positions 4, 6, 7 and 11 are lysine (K) or arginine (R), can bind to AchR in a manner with high specificity as a whole.

[0219] From the above results, it was confirmed that the acetylcholine receptor binding peptide of the present invention comprising the amino acid sequence represented by [Chemical Formula 1], [Chemical Formula 2], [Chemical Formula 3] or [Chemical Formula 4] can bind to AchR with high specificity.

[0220] [Chemical formula 1]

[0221] X L -(K or R)-X-(K or R)-X M -(K or R)-X N

[0222] (The above X L , X M , X N Each independently represents 1 to 8, and X represents a sequence consisting of one arbitrary amino acid).

[0223] [Chemical formula 2]

[0224] (K or R)-X-(K or R)-(K or R)-X M-1 -(K or R)

[0225] (The above X M-1 is 1 to 3, and X represents a sequence consisting of one arbitrary amino acid).

[0226] [Chemical formula 3]

[0227] X L -(K or R)-X-(K or R)-(K or R)-X M-1 -(K or R)

[0228] (The above X L , X M-1 Each independently represents 1 to 3, and X represents a sequence consisting of one arbitrary amino acid).

[0229] [Chemical formula 4]

[0230] X L -(K or R)-X-(K or R)-(K or R)-X M-1 -(K or R)-X N

[0231] (The above X L , X M-1 , X N Each independently represents 1 to 3, and X represents a sequence consisting of one arbitrary amino acid).

[0232] The amino acid sequence was expressed in a certain format based on important peptide sites and sequences, and a library of the peptides was prepared. It was confirmed that the prepared library as a whole binds to the acetylcholine receptor and inhibits its action.

[0233] And, if Fig.13 As shown, it was confirmed that the 8mer, 11mer and 14mer random peptide libraries obtained from the input phage of the first bio-panning showed higher AchR binding specificity than streptavidin, while the 18mer random peptide library obtained from the input phage of the first bio-panning had low binding specificity to AchR.

[0234] Thus, it was confirmed that the 8- to 14-mer random peptides maintained binding to AchR, but the 18-mer random peptide had reduced binding to AchR. This difference in binding strength to AchR is expected to occur due to the number of random amino acids (X).

[0235] Example 13-3. Screening for optimized peptides with improved binding ability to acetylcholine receptors

[0236] Further screening was performed to screen out optimized peptides with improved binding affinity to AchR from the 4th and 5th biopanning input phages with high binding affinity and specificity to AchR (which can be confirmed from Examples 13-1 and 13-2).

[0237] After the 4th and 5th bio-panning output phages of Example 13-1 were inoculated into E. coli, they were plated onto agar medium in such a manner that about 100 to 200 plaques were produced per plate. Each plaque was inoculated into 1 ml of SB liquid medium containing 50 μg / ml ampicillin using a sterile pipette tip, and cultured at 37°C for 5 hours with shaking, and 30 μl of helper phage was added respectively, and cultured at 37°C for one day at 200 rpm. The culture medium was centrifuged at 12,000 rpm for 2 minutes to recover the supernatant, and then 2% BSA was added for phage screening.

[0238] In a 96-well ELISA plate, 50 μl of 5 μg / ml AchR or streptavidin was added to each well and placed at 4°C for 1 day. The next day, the solution in each well was discarded, 2% BSA was added, and the plate was blocked at room temperature for 2 hours. After that, all the solution was discarded and the plate was washed 3 times with Tris (20 mM pH 7). 100 μl of each phage obtained from the plaque prepared in the above manner was inoculated into the wells, 100 μl was inoculated into each well, and placed at 30°C for 1 hour. After removing all the solution in the wells and washing 3 times with Tris (20 mM pH 7), 100 μl of HRP-coupled anti-M13 antibody diluted 1:2000 was added to each well and reacted at 30°C for 1 hour. After washing three times with Tris (20mM pH7), 100μl of tetramethylbenzidine solution was added to each well to induce color reaction, and then 100μl of 1M H2SO4 was added to terminate the reaction, and the absorbance was measured at 450nm (OD450). The measured absorbance was converted into the ratio of AchR absorbance to streptavidin absorbance (AchR signal / streptavidinsignal), and the results were as follows: Figures 14 to 16 shown.

[0239] like Figures 14 to 16 As shown, it was observed that different phages had different binding abilities to AchR, and the phage with the highest ratio of AchR absorbance to streptavidin absorbance was selected. The results are shown in Tables 10 to 12, and the results confirmed that the optimized peptides 8mer (L1), 11mer (L2), and 14mer (L3) all showed higher AchR binding ability and specificity than S peptide-2 (positive control).

[0240] Plasmid DNA was purified from the phage screened in the above manner, and peptide sequence analysis was performed using the purified plasmid DNA and a primer for base sequence analysis consisting of GATTACGCCAAGCTTTGGAGC, thereby screening for an optimized peptide whose sequence was confirmed and had excellent binding specificity to AchR.

[0241] In addition, in order to compare with the peptide of the amino acid sequence described in Korean Patent Publication No. 10-2014-0139010, the peptide of the amino acid sequence was synthesized in the manner shown in Table 13 below, and the binding specificity to AchR was confirmed in the same manner as the above method, and the binding specificity similar to that of S peptide-2 was confirmed. However, compared with the entire 11mer or 14mer library, the sequence of R repeats or the sequence of G repeats at both ends of 8mer showed a low level of binding specificity. This is considered to be due to the electric charge or steric conformation characteristics of the peptide.

[0273] <Example 14. Confirmation of the binding ability of the optimized peptide to the acetylcholine receptor>

[0274] In the above Example 13-3, 40 optimized peptides with excellent binding specificity to AchR were screened from each library and synthesized, and their binding forces to AchR (Ru; Resonance Units) were compared using the surface plasmon resonance (SPR) analysis method of Example 2. At this time, the optimized peptides were operated under the concentration conditions of 3μM and 10μM, and the results were as follows: Figures 17 to 19 As shown, S peptide-2 was used as a positive control. The 40 optimized peptides of 8mer (L1), 11mer (L2), and 14mer (L3) all showed higher AchR binding than S peptide-2 (positive control), and 20 peptides with high binding to AchR were derived from each library.

[0275] <Example 15. Confirmation of the inhibitory effect of each optimized peptide (L1, L2, L3) on acetylcholine receptor>

[0276] In order to confirm the AchR inhibitory effect of the 8mer, 11mer and 14mer peptides with excellent binding ability to AchR confirmed in Example 14 above, the AchR inhibitory effect was confirmed in the same manner as in Example 3 above. At this time, the concentration of each peptide was treated at 20 μM, and S peptide-2 was also treated as a control group. In addition, high concentrations of 400 μM or 600 μM of nicotine were added to confirm the superiority of the AchR inhibitory ability of the optimized peptides. The results are as follows: Figures 20-22 shown.

[0277] like Figures 20-22As shown, when a high concentration of 400 μM nicotine was added and the peptide concentration was 20 μM, the AchR inhibition rate of S peptide-2 as the control group was about 10%, that is, almost none, while the 8mer, 11mer, and 14mer peptides all had an inhibition rate of more than 50% on the AchR, confirming that the inhibitory effect was superior to that of S peptide-2. Among them, the 8mer L1-13, the 11mer L2-110, and the 14mer L3-27, 28, and 37 peptides showed an inhibitory effect close to 100%. Further, it was confirmed that the inhibition rate of the peptides on the AchR action in the cell was almost consistent with the binding force of each peptide and AchR in Example 14 above.

[0278] <Example 16. Confirmation of Acetylcholine Receptor Binding Ability of Representative Peptides>

[0279] The binding capacity (Ru; Resonance Units) of the representative peptides L1-13, L2-110, L3-27, L3-28, and L3-37 determined in Example 15 was compared with that of AchR using the surface plasmon resonance (SPR) analysis method of Example 2. At this time, the analysis was performed under the same conditions of 3 μM peptide concentration. The results are shown in FIG. Fig.23 shown.

[0280] like Fig.23 As shown, the binding ability of 11mer L2-110 and 14mer L3-27, 28, 37 to AchR is higher than that of 8mer L1-13, and the 14mer L3-27, 28, 37 peptide has the highest binding ability. Thus, it was confirmed that the peptide of the present invention also showed high binding ability to AchR when formed in the form of 8mer or 11mer, and it was confirmed that it had the best binding ability when it was 14mer.

[0281] <Example 17. Confirmation of the inhibitory effect of representative peptides L2-110, L3-27, 28, 37 on acetylcholine receptors>

[0282] In order to confirm the AchR inhibitory effect of the L2-110, L3-27, L3-28, and L3-37 peptides that have excellent binding ability to AchR in Example 16, the AchR inhibitory effect was confirmed in the same manner as in Example 3. At this time, each peptide was treated at different concentrations, and S peptide-2 was also treated as a control group. The results are shown in FIG. Fig.24 shown.

[0283] like Fig.24As shown, at a high concentration of 400 μM nicotine, S peptide-2 inhibited AchR action by 100% at 80 μM, but could not inhibit at a concentration of 70 μM. 11mer L2-110 and 14mer L3-27 inhibited AchR action by 100% at 10 μM, but could not inhibit at a concentration of 5 μM. 14mer L3-28 inhibited AchR action by 100% at 5 μM, but could not inhibit at a concentration of 2.5 μM. In addition, L3-37, also a 14mer, inhibited by 100% at 2.5 μM and also inhibited by 50% at 1 μM.

[0284] Based on this result, Fig.25 The inhibitory ability to nicotinic acetylcholine receptors is shown in multiples. Compared with S peptide-2, L2-110 and L3-27 have an inhibitory effect 8 times stronger, L3-28 is 16 times, and L3-37 is 32 times stronger. Finally, it was confirmed that the excellent inhibitory effect can be shown in a manner proportional to the acetylcholine receptor binding ability of Example 15.

[0285] <Example 18. Confirmation of binding ability to acetylcholine receptor based on different modifications at each end of representative peptides>

[0286] Each end of the L2-110, L3-27, L3-28, and L3-37 peptides confirmed in Example 17 was not modified to confirm changes in binding ability to AchR. Specifically, in the same manner as in Example 8, the peptides were modified with palmitoyl, myristic acid, or stearic acid as fatty acid derivatives, or acetylated or PEGylated, and compared with the unmodified basic peptide. The results are shown in Figures 26 to 29 middle.

[0287] like Figures 26 to 29 As shown, when the fatty acid derivatives were bound to the ends of the peptides of the present invention, the binding force of all peptides increased by about 10 times (palmitoyl-, myristyl-, stearic-). At this time, it was confirmed that the peptides modified with palmitoyl showed higher binding force than the peptides modified with other fatty acid derivatives.

[0288] When the termini of the peptides of the present invention were acetylated, the binding affinity to AchR was similar to that when the termini of the peptides were not modified, and when the termini of the peptides were PEGylated, the binding affinity to AchR was reduced by about 50% compared to that when the termini of the peptides were not modified.

[0289] In addition, if Fig.30As shown, when the termini of the peptides of the present invention were modified with myristic acid or stearic acid, a micellar structure was confirmed to be formed, as in the case of palmitoyl binding in the above Example 8.

[0290] <Example 19. Confirmation of palmitoyl-L2-110, palmitoyl-L3-27, palmitoyl-L3-28, palmitoyl-L3-37 Acetylcholine receptor inhibition>

[0291] The AchR inhibitory effect was confirmed for the palmitoyl-L2-110, palmitoyl-L3-27, palmitoyl-L3-28, and palmitoyl-L3-37 peptides that had excellent binding ability to AchR in Example 18 by the same method as in Example 3. At this time, bungarotoxin was also treated as a control group. Fig.31 Shown in.

[0292] like Fig.31 As shown, palmitoyl-L3-37 had the highest binding affinity to AchR, followed by palmitoyl-L3-28, palmitoyl-L3-27, and palmitoyl-L2-110 showing similar levels.

[0293] Example 20. Confirmation of palmitoyl-L2-110, palmitoyl-L3-27, palmitoyl-L3-28, and palmitoyl-L3-37 peptides Cytotoxicity>

[0294] To evaluate the toxicity of palmitoyl-L2-110, palmitoyl-L3-27, palmitoyl-L3-28, and palmitoyl-L3-37 peptides, WST assay was performed using TE671 cells. Figures 32-35 Shown in.

[0295] like Figures 32-35 As shown, it was confirmed that all peptides showed no cytotoxicity even at a concentration of 10 μM.

[0296] Example 21. In vivo expression of palmitoyl-L3-37 vivo) Efficacy Analysis>

[0297] Animal efficacy evaluation was performed using palmitoyl-L3-37, which has the best binding ability to acetylcholine receptors in Example 1 above. Palmitoyl-L3-37 was injected into the right hind thigh muscle (IM) of 6-week-old female BALB / c mice at a concentration of 10 mg / kg. The gait analysis (CatWalk) data of the mice before injection was compared with the gait analysis (CatWalk) data of the mice 30 minutes after injection. The results are as follows: Fig.36 shown.

[0298] like Fig.36As shown, it was confirmed that the area of ​​the sole of the right hind leg of the mouse after injection was reduced compared with that before injection of palmitoyl-L3-37 (A). It was also confirmed that after injection of palmitoyl-L3-37, the area of ​​the sole of the mouse foot contacting the floor (B) and the average value of the maximum area (C) were also reduced.

[0299] Thus, it was found that palmitoyl-L3-37 binds to acetylcholine receptors, thereby affecting muscle relaxation in animals by inhibiting acetylcholine.

[0300] <Example 22. Animal efficacy (ED50) and animal toxicity (LD50) evaluation of palmitoyl-L3-37>

[0301] Animal efficacy (ED50) was assessed by digit abduction score (DAS) analysis. The DAS assay was developed to measure the local muscle weakening efficacy of drugs injected intramuscularly (IM) into the skeletal muscle of the mouse hind limb, and botulinum toxin was also evaluated in the same manner (Aoki, 1999).

[0302] Specifically, the DAS value of palmitoyl-L3-37 of Example 18 above was evaluated. 45 6-week-old female BALB / c mice were randomly divided into groups of 5, and were divided into treatment groups to be injected with palmitoyl-L3-37 at 0.1 mg / kg, 1 mg / kg, 3 mg / kg, 10 mg / kg, and 25 mg / kg, and treatment groups to be injected with saline solution (saline) (sterilized 0.9% NaCl) or Bungarus toxin at 70 μg / kg. Then, palmitoyl-L3-37, saline solution, and Bungarus toxin were injected into the hind thigh muscles of mice at the above concentrations and in an amount of 50 μl. Thereafter, the body weight of the mice and the soles of the feet at the injection site were observed and recorded every day. The results are as follows: Figure 37 to Figure 39 shown.

[0303] Fig.37 The results of the observations were obtained 7 days after the injection. Ten minutes after the administration of the sample (day 0), the efficacy of the palmitoyl-L3-37 1 mg / kg administration group was DAS 2, the efficacy of the palmitoyl-L3-37 3 mg / kg, 10 mg / kg and 25 mg / kg administration groups was evaluated as DAS 4, and the efficacy of the palmitoyl-L3-37 1 mg / kg administration group and the saline solution or Bungarus toxin administration group (control group) was evaluated as DAS 0. Thus, it was found that the efficacy (ED50) of palmitoyl-L3-37 in animal experiments is 1 mg / kg. In addition, during the 7-day observation period, it was confirmed that the DAS values ​​of the other groups except the palmitoyl-L3-37 25 mg / kg administration group decreased and recovered, but the palmitoyl-L3-37 25 mg / kg administration group maintained DAS 4.

[0304] Fig.38The results of observing the palmitoyl-L3-37 25 mg / kg administration group at intervals of one week until 21 days after administration confirmed that the DAS value of the palmitoyl-L3-37 25 mg / kg administration group gradually decreased after the 7th day of administration, and after the 19th day of palmitoyl-L3-37 administration, the DAS value decreased to below 1 and recovered. Thus, it was found that the efficacy of palmitoyl-L3-37 is reversible.

[0305] Finally, the acute toxicity of palmitoyl-L3-37 was evaluated by measuring body weight every day for 7 days after administration (refer to Fig.39 ), it was confirmed that the body weight of mice in all groups gradually increased within 7 days, and no toxicity was produced in the groups treated with palmitoyl-L3-37 even in the group treated with the highest concentration of 25 mg / kg.
