Description

  The present invention relates to a tyrosinase activity inhibitor.

Melanin plays an important role in protecting the human body from the harmful effects of ultraviolet radiation. However, excessive production of melanin causes spots, freckles, melanosis and the like. Melanin is known to be formed or synthesized in skin tissue. Tyrosinase is a rate-limiting enzyme of melanogenesis reaction, hydroxylation from L-tyrosine to 3,4-dihydroxy-L-phenylalanine (hereinafter referred to as L-DOPA), L-DOPA to L-DOPA quinone (quinone) It catalyzes the two-step reaction of oxidation to melanin and promotes melanin formation. The first stage reaction is called monophenolase activity, and the second stage reaction is called diphenolase activity.

  An effective way to inhibit melanin synthesis is to block (prevent) tyrosine hydroxylation.

  As tyrosinase inhibitors, those using kojic acid or arbutin have also been developed (for example, Patent Documents 1 and 2). However, in these inventions, strong cytotoxicity has been a problem, and further improvement has been demanded for practical application to cosmetics, foods and drinks, pharmaceuticals and the like.

  Furthermore, although a 10-amino acid sequence (SEQ ID NO: 3) is known as a peptide showing tyrosinase inhibition, a method using rice bran is not known.

Similarly to Test Example 4, the solution obtained by dissolving the hydrolyzate after freeze-drying obtained in Example 3 and Comparative Example 3 with 5 ml of water was subjected to gel filtration chromatography (trade name: Biogel P-6 packed) Micro bio spin column (Bio-Gel P-6 Gel), product code: 150-4134, 100 g, fine polyacrylamide beads for size exclusion chromatography, 45-90 μm wet bead size, 1,000-6,000 MW fractionation range, solvent: distilled water , Bio-Rad Laboratories Co., Ltd.), and the absorbance of each fraction at a wavelength of 210 nm was measured. The results are shown in FIG. 4A. Monophenolase activity and diphenolase activity were measured for the 60-99 fractions by the method described above. The results are shown in FIG. 4B. As shown in FIG. 4B, the 72nd to 83rd fractions both showed strong inhibitory activity against monophenolase and diphenolase. Therefore, the 72nd to 83rd fractions were collected.
Subsequently, purification by gel filtration chromatography using a Superdex Peptide 10/300 GL column (GE Healthcare Japan Co., Ltd.) was performed. 1 mL was fractionated per fraction, and the absorbance at 210 nm of the obtained eluate was measured. The result is shown in FIG. 5A. Each of the 11 fractions collected was freeze-dried and redissolved in water, and then the monophenolase inhibitory activity was measured by the above method. The result is shown in FIG. 5B. As shown in FIG. Nine fractions showed the highest inhibitory activity.

  Next, no. Nine fractions were obtained from Cadenza CD-C18 (particle size: 3 μm, pore size: 12 nm, stationary phase: octadecyl group, polymeric end capping, inner diameter: 10 mm, product code: CD0P5, column length: 150 mm, Intact Co., Ltd.) Purification was performed by reverse phase chromatography using Intakt Co.)). Specifically, in 0.1% trifluoroacetic acid, the acetonitrile concentration was 0% (0 to 5 minutes), 0 to 5.2% (5 to 5.1 minutes), 5.2 to 33.6. % (5.1 to 50 minutes), 33.6 to 80% (50 to 50.1 minutes) and 80% (50.1 to 55 minutes), the time program is set, and the flow rate is 1.0 mL Elution was carried out at a rate of 1 minute. The liquid volume of one fraction was taken as 3.0 mL. The concentration of the peptide was measured by measuring the absorbance of the eluate at 210 nm. The results are shown in FIG. 6A. Each peak of A to O obtained was collected and lyophilized. Then, it re-dissolved with water and the monophenolase inhibitory activity was measured by said method. The result is shown in FIG. 6B. As shown in FIG. 6B, monophenolase inhibitory activity of 50% or more was observed in many peak fractions.

  Furthermore, in order to make each peak single, purification by re-reverse phase chromatography was performed using the same column of Cadenza CD-C18. In 0.1% trifluoroacetic acid, the concentration of acetonitrile was 0% (0-3 minutes), 0-30.8% (3-55 minutes), 30.8-80% (55-55.1 minutes) And the time program was set so that it might become 80% (55.1-60 minutes), the flow rate was adjusted to 1.0 mL / min, and it eluted. The liquid volume of one fraction was taken as 3.0 mL. The concentration of the peptide was measured by measuring the absorbance of the eluate at 210 nm. By this re-chromatography, the peptide contained in the almost single peak is converted into MALDI-TOF MS (Matrix Assisted Laser Desorption Ionization (MALDI) and Time of Flight (TOF)). ) A device that mainly determines the mass of biopolymers by combining a mass spectrometer (MS) (hereinafter also referred to as “MALDI-TOF mass spectrometer”); trade name: Auto Flex-IIITM; Bruker Daltonics ) (BRUKER DALTONICS)).

  For the analysis, α-cyano-4-hydroxycinnamic acid (CHCA) (Bruker Daltonics) was selected as the matrix. CHCA was dissolved in a mixture of acetonitrile and trifluoroacetic acid (100% acetonitrile: 0.1% trifluoroacetic acid (TFA) = 1: 2) to prepare a saturated CHCA solution. Mix the sample solution and CHCA saturated solution 1: 1 in the sample tube, drop the mixed solution on the dedicated analysis plate (MTP 384 target plate ground steel TF, Bruker Daltonics), and then dry completely Left to stand. For calibration, preparation and dropping were performed in the same manner as the sample, using a calibration standard product (trade name: Protein Calibration Standard II, Bruker Daltonics). For the operation of the MALDI-TOF mass spectrometer, control software (trade name: flexControlTM, Bruker Daltonics Co., Ltd.) was used. The obtained MS and MS / MS spectra were analyzed using interactive data analysis software (trade name: flexAnalysisTM, Bruker Daltonics) and protein analysis software (trade name: biotoolsTM, Bruker Daltonics). After the processing, candidate peptides were searched using an analysis software (trade name: Mascot search ™, Bruker Daltonics Co., Ltd.) and collated with the NCBI database.

  The result of re-chromatography of the peak E fraction using the same column is shown in FIG. 7A. From the result of the elution pattern, it was found that each peak fraction became almost single. Moreover, the peptide contained in each obtained single peak was identified using MALDI-TOF MS. As a peptide contained in the peak, SEQ ID NO: 7 could be identified. This peptide was found to be the 48th to 57th partial sequence of Os03g0793700 (RmlC-like jelly roll fold domain containing protein).

  The result of re-chromatography of the peak G fraction using the same column is shown in FIG. 7B. From the result of the elution pattern, it was found that each peak fraction became almost single. Moreover, the peptide contained in each obtained single peak was identified using MALDI TOF-MS. As a peptide contained in the peak, SEQ ID NO: 8 could be identified. This peptide was found to be the 107th to 112th partial sequence of Os03g0793700 (RmlC-like jelly roll fold domain containing protein). Therefore, it was found that the peptides identified from the peak E fraction and the G fraction were contained in the same protein.

  The result of re-chromatography of the peak H fraction using the same column is shown in FIG. 7C. From the result of the elution pattern, it was found that each peak fraction became almost single. Moreover, the peptide contained in each obtained single peak was identified using MALDI TOF-MS. SEQ ID NO: 9 could be identified as a peptide contained in the peak. This peptide was found to be a partial sequence from the 165th to 171st positions of Os03g0197300 (Similar to Cupin family protein).

[Examples 4 to 6]
In the same manner as in Example 1, peptides (peptides E, G, H) described in SEQ ID NOs: 7 to 9 were chemically synthesized to obtain peptides with a purity of 95% or more. 1 g of the obtained peptide was added to 5 liters of water and dissolved at room temperature to obtain a sample solution.

[Test Example 6]
Monophenolase activity was measured by the method described above using the peptides of Examples 4-6. The measurement results of Examples 4 to 6 are shown in FIGS.

  As shown in FIGS. 8A to 8C, the peptides of Examples 4 to 6 were also confirmed to have tyrosinase inhibitory activity.

  Attempts were made to identify peptides for each peak in FIG. 6A, but so far only 6 peptides were found. Peptides other than SEQ ID NOs: 7-9 are peptides of SEQ ID NOs: 12-14. From the peak H, two types of peptides were identified, but inhibitory activity could be confirmed only in SEQ ID NO: 9 (the peptide of SEQ ID NO: 13 had no activity). Peptides could be identified from peak F and peak J (SEQ ID NOs: 12 and 14), but they did not show inhibitory activity. Therefore, from the result of FIG. 6B, it is considered that many peaks further contain a tyrosinase-inhibiting peptide that could not be identified this time.

  Similar to SEQ ID NO: 1, it was suggested that a peptide having tyrosine at the C-terminus has tyrosinase inhibitory activity. The reason why a peptide having tyrosine at the C-terminal inhibits tyrosinase is that the binding of tyrosinase and the substrate is prevented by binding of tyrosine at the C-terminal to tyrosinase. However, peptides whose C-terminal is not tyrosine have also been reported to have tyrosinase inhibitory activity (J. Dermatol. Sci., 51, 158-170 (2008); Bichim. Biophys. Acta, 2012 on line / Doi: 10.1016 / j.bbagen.2012.05.003).

  It was also suggested that the strength of tyrosinase inhibitory activity was not affected only by the number of amino acid residues of the peptide. This result suggested that not only the C-terminal tyrosine of the peptide but also other amino acid residues are involved in tyrosinase inhibition.

  The composition of the present invention comprising a peptide, a rice bran protein hydrolyzate and a rice bran protein hydrolyzate has no cytotoxicity, has an excellent tyrosinase inhibitory activity, and can be used in cosmetics, pharmaceuticals, foods and drinks, and the like.
