[0153] (Korean Laid-Open Patent Publication No. 10-2008-0094781)

[0154] In addition, the HRF-binding peptide according to the present invention can be administered by using nanoparticles (liposomes, exosomes, etc.), or by coating or loading on the skin through a patch or microneedle.

[0155] In addition, the HRF-binding peptide according to the present invention can be used for drug delivery using a cell-penetrating peptide. For example, the peptide disclosed in Korean Laid-Open Patent Publication No. 10-2017-0114997 can be used.

[0156] That is, in one aspect of the present invention, there is provided a composition for diagnosing, preventing or treating allergy, malaria, autoimmune disease, acute or chronic inflammatory disease, hypertension or cancer, containing the HRF-binding peptide and the peptide consisting of the following amino acid sequence:


R1-R2-R3-R4-R5-R6-R7-R8-R9-R10 [0157] R1 is any one amino acid selected from M, L or P, [0158] R2 is any one amino acid selected from I, A, L, P or H, [0159] R3 is any one amino acid selected from I, L, A, P, or H, [0160] R4 is any one amino acid selected from F, E, A, L, P or H, [0161] R5 is any one amino acid selected from R or K, [0162] R6 is any one amino acid selected from A, M, I, P, H or L, [0163] R7 is any one amino acid selected from L, A, P or H, [0164] R8 is any one amino acid selected from I, L, A, P or H, [0165] R9 is any one amino acid selected from S, E or Y, [0166] R10 is any one amino acid selected from H, K, R, P or L, and any one amino acid selected from KK, KKK, and KKKK can be added thereto. However, except when the sequence is MIIFRIAASHKK, MIIFRALISHKK, MIIFRAAASHKK, LIIFRIAASHKK, MIIFRIAAYHKK, MIIFKIAASHKK, LIIFRILISHKK, or MIIFRILISHKK.

[0167] Meanwhile, the amino acid sequence of the peptide according to the present invention can be modified according to the conventional techniques known in the art. For example, the peptide of the present invention can be modified by increasing or decreasing the number of amino acids. In addition, within a range that does not reduce the activity of the peptide according to the present invention, the peptide can be modified by changing the order of specific residue components except for the residues that are directly involved in binding or must be conserved. Modifiable amino acids can be modified not only with natural L-α-amino acids, but also with β, γ, δ amino acids as well as D-α-amino acid derivatives. Typically, as a result of examining the effect of electrostatic force or hydrophilicity on binding using a peptide in which one amino acid is substituted, it can be seen that the sensitivity changes when positively charged amino acids (for example, Lys, Arg, His) or negatively charged amino acids (for example, Glu, Asp, Asn, Gln) are substituted. As such, the number or type of the residues to be substituted or added is determined by the required space between the essential binding points and the required functions such as hydrophilicity or hydrophobicity. By such substitution, the affinity of the peptide according to the present invention to the target protein can be further increased. Significant changes in function can also result from the substitution. The selection of the residue to be modified has a great influence on the electrical conductivity, hydrophobicity and maintaining the basic backbone of the peptide such as side chain change or helix structure change of the molecule present at the target position. In general, substitution of a hydrophilic residue such as serine with a hydrophobic residue such as leucine, isoleucine, phenylalanine, valine or alanine, substitution of an electrically positive residue such as lysine, arginine or histidine with an electrically negative residue such as glutamic acid or aspartic acid, or substitution of an amino acid having no side chain, such as glycine, with a residue having a bulky side chain causes a significant change in the properties of a peptide. In consideration of the above-mentioned facts, those of ordinary skill in the art can modify the specific peptide using conventional techniques within the range of maintaining, or not increasing/impairing its binding ability to HRF and the histamine secretion inhibitory activity, and this is within the scope of the present invention.

[0208] As a result, as shown in FIG. 22, it was confirmed that the dTBP2 according to Preparative Example 4 and the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 effectively inhibited ovalbumin-specific IgE secretion in plasma. Specifically, the dTBP2 according to Preparative Example 4 reduced ovalbumin-specific IgE secretion by about 50%, and the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 reduced ovalbumin-specific IgE secretion by about 50%.

[0209] From the above results, it was confirmed that the dTBP2 and N-terminal 10K PEG-conjugated dTBP2 were very effective in inhibiting ovalbumin-specific IgE secretion in plasma.

[0210] Next, in order to confirm whether there is an effect of inhibiting ovalbumin-specific IgE secretion in plasma even when administered in a small number of times, the dTBP2 of Preparative Example 4 and Example 3 was administered to the mouse model of Example 4-1 through intraperitoneal injection once in 4 days for a total of 2 times for 8 days inducing bronchial asthma and rhinitis. The amount of ovalbumin-specific IgE secretion was measured and quantified by the enzyme immunosorbent detection method in the same manner. The results are shown in FIG. 23.

[0211] In addition, the dTBP2 of Preparative Example 4 and Example 3 was administered to the mouse model of Example 4-1 through intraperitoneal injection once on the 1st day of 8 days inducing bronchial asthma and rhinitis. The amount of ovalbumin-specific IgE secretion was measured and quantified by the enzyme immunosorbent detection method in the same manner. The results are shown in FIG. 24.

[0212] As a result, as shown in FIGS. 23 and 24, it was confirmed that the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 was effective in inhibiting ovalbumin-specific IgE secretion even when administered only once within the induction period of bronchial asthma and rhinitis. It was also confirmed that the N-terminal 10K PEG-conjugated dTBP2 of Example 3 had better inhibitory ability than the dTBP2 of Preparative Example 4.

[0213] Next, in order to confirm whether there is an inhibitory effect on ovalbumin-specific IgE secretion in plasma even when administered after inducing bronchial asthma and rhinitis, the dTBP2 of Preparative Example 4 and Example 3 was administered to the mouse model of Example 4-1 through intraperitoneal injection once on the 5th day of 8 days inducing bronchial asthma and rhinitis. The amount of ovalbumin-specific IgE secretion was measured and quantified by the enzyme immunosorbent detection method in the same manner. The results are shown in FIG. 25.

[0214] As a result, as shown in FIG. 25, it was confirmed that the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 had an ovalbumin-specific IgE secretion inhibitory effect even after only one administration after inducing bronchial asthma and rhinitis. From the above results, it was confirmed that the ovalbumin-specific IgE secretion inhibitory effect could be further improved by pegylation of dTBP2 using the aldehyde-PEG (10000).

<Experimental Example 9> Pharmacokinetic Analysis of dTBP2 and N-Terminal 10K PEG-Conjugated dTBP2

[0215] The dTBP2 according to Preparative Example 4 and the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 were administered to 7-8 weeks old ICR mice that had undergone the acclimatization period at the concentration of 10 mg/kg IV, respectively, and then blood was collected according to a predetermined time. The dTBP2 of Preparative Examples 4 and Example 3 was added to a solution prepared in DMSO:PEG400:DW=5:55:40, and this was administered at the concentration of 5 mL/kg. Blood samples were taken at 0.083, 0.25, 0.5, 1, 2, 4, and 8 hours post injection. The blood was centrifuged at 4° C., 3000 rpm for 10 minutes, to which cold acetonitrile containing internal standard was added in an amount 4 times the plasma component, and then deproteinization was carried out. After centrifugation again at 4° C., 13000 rpm for 10 minutes, the supernatant was collected and analyzed by Agilent 6460 LC-MS/MS. Pharmacokinetic analysis was performed with Phoenix WinNonlin (Pharsight ver 6.4, USA) using a non-compartmental analysis model. The results are shown in FIG. 26, and the pharmacokinetic analysis results were analyzed and shown in Table 2 below.

[0216] As a result, as shown in FIG. 26, it was confirmed that the stability of the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 in plasma was improved by the dTBP2 according to Preparative Example 4. In addition, as shown in Table 1, it was confirmed that the half-life of the PEGylated dTBP2 of Example 3 was increased by about 1.6 times compared to the dTBP2 of Preparative Example 4. In addition, as shown in FIG. 18, it was confirmed that the initial plasma concentration of the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 was about 1000 times higher than that of the dTBP2 according to Preparative Example 4. From the above results, it was found that the stability was increased by about 1000 times by pegylation of the peptide of Preparative Example 4.

<Experimental Example 10> Confirmation of Metabolic Stability of 10K PEG-Conjugated dTBP2

[0217] In order to evaluate the first-step metabolic stability of the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 in the liver, the following evaluation was performed using mouse and human liver microsomes. After incubating the mouse and human liver microsomes diluted with 0.5 M potassium phosphate buffer (pH 7.4) at 37° C. for 5 minutes, NADPH for activating the metabolic enzyme system was reacted with the peptide of Example 3 at 37° C. for 30 minutes. Then, the amount of the peptide of Example 3 remaining was analyzed. Upon completion of the reaction, cold acetonitrile containing internal standard was added, and then deproteinization was carried out. The reactant was centrifuged at 4° C., 4000 rpm for 15 minutes, and the supernatant was analyzed by LC-MS/MS. The system was verified with buspirone, a reference material. The results are shown in Table 3.

[0218] In the evaluation of the experiment, the microsome stability evaluation criteria according to the % value, which is the result of the reaction experiment for 30 minutes, are as follows (R. SCOTT OBACH, Prediction of human clearance of twenty-nine drugs form hepatic microsomal intrinsic clearance data: An examination of in vitro half-life approach and nonspecific binding to microsomes, 1999, 27, (11): 1350-59).

[0219] >90%: very stable compound with a half-life longer than 3 hours

[0220] 70˜90%: stable compound with a half-life of 1 to 3 hours

[0221] 50˜70%: relatively stable compound with a half-life of 30 to 60 minutes

[0222] 30˜50%: relatively unstable compound with a half-life of 15 to 30 minutes

[0223] <30%: unstable compound with a half-life of less than 15 minutes

[0224] Referring to the above evaluation criteria, the N-terminal 10K PEG-conjugated dTBP2 according to Example 3 of the present invention was confirmed to be a stable compound with a half-life of about 1 to 3 hours since the remaining drug was more than 75% after 30 minutes in both mice and humans. Therefore, since the peptide can exert a drug effect with high stability in vivo, the number of administration can be reduced, so that it can be effectively used as a drug.

[0225] As mentioned above, the present invention has been described in detail through the preferred preparative examples, examples and experimental examples, but the scope of the present invention is not limited to the specific examples, and should be interpreted by the appended claims. In addition, those of ordinary skill in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
