Description

本発明は、N−ヒドロキシコハク酸イミドを利用したチロシナーゼ活性阻害剤、メラニン産生抑制剤及び美白用皮膚外用剤に関する。   TECHNICAL FIELD The present invention relates to a tyrosinase activity inhibitor, a melanin production inhibitor and a whitening skin external preparation using N-hydroxysuccinimide.

従来より、乳液、クリーム、化粧水、パック、洗浄料、分散液、軟膏、液剤、エアゾール、貼付剤、パップ剤、リニメント剤等の皮膚外用剤には、これらに所定の薬効を付与することを目的として種々の薬効成分が加えられている。例えば、日焼け等により生じる皮膚の黒化、色素沈着により生ずるシミ、ソバカス等を予防又は改善する為に、アルブチン、アスコルビン酸類(例えばVC−PMg)等の美白剤が加えられている(例えば、特許文献1および2、非特許文献1および2)。しかしながら、これらの美白剤では、皮膚外用剤の安定性を低下させたり、あるいは、製剤中で変質する等して所期の薬効が得られない場合があり、その改善が望まれていた。   Conventionally, skin external preparations such as emulsions, creams, lotions, packs, cleaning agents, dispersions, ointments, liquids, aerosols, patches, poultices, liniments, and the like have been given a prescribed medicinal effect. Various medicinal ingredients are added for the purpose. For example, whitening agents such as arbutin and ascorbic acids (for example, VC-PMg) have been added in order to prevent or improve skin darkening caused by sunburn, stains caused by pigmentation, buckwheat etc. (for example, patents) Documents 1 and 2, Non-patent documents 1 and 2). However, in these whitening agents, the stability of the external preparation for skin may be lowered, or the desired drug efficacy may not be obtained due to deterioration in the preparation, and improvement thereof has been desired.

本発明は、安定的に配合可能で、且つ美白効果に優れた新規なチロシナーゼ活性阻害剤及びメラニン産生抑制剤を提供することを課題とする。また、本発明は、安定性が良好で、且つ美白効果に優れた皮膚外用剤を提供することを課題とする。   This invention makes it a subject to provide the novel tyrosinase activity inhibitor and melanin production inhibitor which can be mix | blended stably and was excellent in the whitening effect. Moreover, this invention makes it a subject to provide the skin external preparation which was excellent in stability and excellent in the whitening effect.

本発明者は鋭意検討した結果、N−ヒドロキシコハク酸イミドが、チロシナーゼの活性を直接的に阻害するとの知見を得、この知見に基づいて本発明を完成するに至った。N−ヒドロキシコハク酸イミドは、銅に対するキレート効果があり、このキレート効果によりチロシナーゼから銅を奪い、その結果、チロシナーゼの活性が阻害されるものと考えられる。例えば、太陽光の照射などによって、メラノサイトが活性化された場合も、N−ヒドロキシコハク酸イミドの存在下では、チロシナーゼの活性が阻害されるので、メラニン産生が抑制され、その結果、優れた美白効果を奏するものと考えられる。   As a result of intensive studies, the present inventor has obtained the knowledge that N-hydroxysuccinimide directly inhibits the activity of tyrosinase, and has completed the present invention based on this knowledge. N-hydroxysuccinimide has a chelating effect on copper, and this chelating effect deprives copper from tyrosinase. As a result, it is considered that the activity of tyrosinase is inhibited. For example, even when melanocytes are activated by sunlight irradiation or the like, the activity of tyrosinase is inhibited in the presence of N-hydroxysuccinimide, so that melanin production is suppressed, resulting in excellent whitening. It is thought that there is an effect.

即ち、本発明は、前記課題を解決するため、N−ヒドロキシコハク酸イミドを有効成分とするチロシナーゼ活性阻害剤、及びメラニン産生抑制剤を提供する。また、本発明は、N−ヒドロキシコハク酸イミドをチロシナーゼ活性阻害剤として又はメラニン産生抑制剤として含有する美白用皮膚外用剤を提供する。また、別の観点から、本発明によって、N−ヒドロキシコハク酸イミドを適用することによるチロシナーゼの活性を阻害する方法、及びN−ヒドロキシコハク酸イミドを適用することによる皮膚細胞内のメラニン産生を抑制する方法が提供される。   That is, this invention provides the tyrosinase activity inhibitor and melanin production inhibitor which use N-hydroxysuccinimide as an active ingredient in order to solve the said subject. Moreover, this invention provides the skin external preparation for whitening which contains N-hydroxysuccinimide as a tyrosinase activity inhibitor or a melanin production inhibitor. Further, from another viewpoint, the present invention suppresses tyrosinase activity by applying N-hydroxysuccinimide, and suppresses melanin production in skin cells by applying N-hydroxysuccinimide. A method is provided.

本発明によれば、優れたチロシナーゼ活性阻害剤及びメラニン産生抑制剤を提供することができる。また、これを含有する皮膚外用剤は、色素沈着に対し高い抑制効果を発揮し、肌のくすみ、日焼けなどによる皮膚の黒化、シミ、ソバカスの防止及び改善等に有効なものである。従って、チロシナーゼ 活性阻害剤及び/又はメラニン産生抑制剤としてN−ヒドロキシコハク酸イミドを含有する皮膚外用剤は、美白及び/又は美肌を目的とする化粧品や医薬品等に有利に利用することができる。   According to the present invention, an excellent tyrosinase activity inhibitor and melanin production inhibitor can be provided. Moreover, the skin external preparation containing this exhibits a high inhibitory effect with respect to pigmentation, and is effective in preventing and improving skin darkening due to skin dullness, sunburn, etc., spots and freckles. Therefore, an external preparation for skin containing N-hydroxysuccinimide as a tyrosinase activity inhibitor and / or a melanin production inhibitor can be advantageously used in cosmetics and pharmaceuticals for the purpose of whitening and / or skin.

以下、本発明について詳細に説明する。
本発明は、N−ヒドロキシコハク酸イミド(hydroxysuccinimide)を有効成分とするチロシナーゼ活性阻害剤、及びメラニン産生抑制剤に関する。本発明では、N−ヒドロキシコハク酸イミドの水和物を用いてもよい。N−ヒドロキシコハク酸イミドは、上記した様に、銅に対するキレート効果がある。例えば塩化銅(CuCl2)の水溶液は波長800nm近傍に吸収極大を示すが、塩化銅水溶液にN−ヒドロキシコハク酸イミドを添加すると、N−ヒドロキシコハク酸イミドと銅がキレート錯体を形成し、その結果、吸収極大の波長がシフトする。また、キレート錯体の形成は、溶液のpH変化を追跡することによっても確認することができる。本発明では、N−ヒドロキシコハク酸イミドの銅に対するキレート効果を利用して、チロシナーゼの活性を直接的に阻害して、メラニン産生を抑制している。
Hereinafter, the present invention will be described in detail.
The present invention relates to a tyrosinase activity inhibitor containing N-hydroxysuccinimide as an active ingredient and a melanin production inhibitor. In the present invention, a hydrate of N-hydroxysuccinimide may be used. N-hydroxysuccinimide has a chelating effect on copper as described above. For example, an aqueous solution of copper chloride (CuCl 2 ) exhibits an absorption maximum in the vicinity of a wavelength of 800 nm. However, when N-hydroxysuccinimide is added to the aqueous copper chloride solution, N-hydroxysuccinimide and copper form a chelate complex. As a result, the wavelength of the absorption maximum shifts. The formation of the chelate complex can also be confirmed by tracking the pH change of the solution. In the present invention, the activity of tyrosinase is directly inhibited by using the chelating effect of N-hydroxysuccinimide on copper to suppress melanin production.

N−ヒドロキシコハク酸イミドは、チロシナーゼ 活性阻害作用及び/又はメラニン産生抑制作用による美白、美肌成分として常法に従い、種々の形態の皮膚外用剤に配合することができる。本発明の皮膚外用剤におけるチロシナーゼ 活性阻害剤及び/又はメラニン産生抑制剤としてのN−ヒドロキシコハク酸イミドの含有量は、好ましくは0.0001〜5質量%(以下単に「%」で示す)であり、より好ましくは0.001〜1%である。この範囲内であれば、N−ヒドロキシコハク酸イミドを安定に配合することができ、チロシナーゼ 活性阻害作用及びメラニン産生抑制作用に優れ、それらによる高い美白及び/又は美肌効果を発揮することができる。   N-hydroxysuccinimide can be blended in various forms of external skin preparations in accordance with conventional methods as a whitening and skin-beautifying component by tyrosinase activity inhibitory action and / or melanin production inhibitory action. The content of N-hydroxysuccinimide as a tyrosinase activity inhibitor and / or a melanin production inhibitor in the external preparation for skin of the present invention is preferably 0.0001 to 5% by mass (hereinafter simply referred to as “%”). Yes, more preferably 0.001 to 1%. If it is in this range, N-hydroxysuccinimide can be blended stably, it is excellent in tyrosinase activity inhibitory action and melanin production inhibitory action, and can exhibit high whitening and / or skin-beautifying effects.

皮膚外用剤の例としては、特に限定されず、例えば、乳液、クリーム、化粧水、パック、洗浄料、メーキャップ化粧料、分散液、軟膏、液剤、エアゾール、貼付剤、パップ剤、リニメント剤等の、いずれの形態の化粧料であっても、外用医薬品等であってもよい。   Examples of the external preparation for skin are not particularly limited, and examples thereof include emulsions, creams, lotions, packs, cleaning agents, makeup cosmetics, dispersions, ointments, liquids, aerosols, patches, poultices, liniments and the like. Any form of cosmetics may be used, such as external medicines.

本発明の皮膚外用剤には、上記必須成分の他に、化粧料や医薬部外品、外用医薬品等に通常使用される各種の成分、即ち、水、アルコール、油剤、界面活性剤、増粘剤、粉体、キレート剤、pH調整剤、各種薬効剤、動植物・微生物由来の抽出物、香料等を、本発明の効果を損なわない範囲で適宜加えることができる。また、N−ヒドロキシコハク酸イミドと、従来公知の美白剤、抗酸化剤、細胞賦活剤、抗炎症剤、紫外線防止剤等の薬効成分を併用して皮膚外用剤としたものは、N−ヒドロキシコハク酸イミドの作用効果にこれら薬効剤の効果が加わり、本発明の効果を更に高めることができる。   In addition to the above essential components, the external preparation for skin of the present invention includes various components that are usually used in cosmetics, quasi-drugs, external medicines, etc., that is, water, alcohol, oils, surfactants, thickeners. Agents, powders, chelating agents, pH adjusting agents, various medicinal agents, extracts derived from animals, plants and microorganisms, fragrances, and the like can be added as appropriate within the range not impairing the effects of the present invention. In addition, N-hydroxysuccinimide and a conventionally known whitening agent, antioxidant, cell activator, anti-inflammatory agent, anti-ultraviolet agent, and other medicinal ingredients are used as a skin external preparation. The effects of these medicinal agents are added to the effects of succinimide, and the effects of the present invention can be further enhanced.

以下に実施例を挙げて本発明をさらに具体的に説明するが、本発明の範囲は下記の実施例に限定されることはない。
[実施例1:チロシナーゼ活性阻害効果]
マッシュルームチロシナーゼを100unit/mLとなる様に、0.1mol/Lリン酸緩衝液に溶解しチロシナーゼ溶液を調製した。L−Dopaを同様に0.1mol/Lリン酸緩衝液に溶解し、0.1%L−Dopa溶液を調製した。N−ヒドロキシコハク酸イミドを37℃に保温した0.1%L−Dopa溶液に各濃度(0〜100μg/mL)で添加した後、上記チロシナーゼ溶液を添加した。各濃度での37℃での反応速度平均を求め、得られた結果から50%の反応阻害を行える濃度(IC50)を算出し、チロシナーゼの直接的な阻害効果を評価した。また、チロシナーゼ活性阻害剤として公知のアルブチン及びVC−PMg(アスコルビン酸リン酸エステルマグネシウム)についても同一の方法でIC50を算出し、結果を比較した。下記表1に算出したIC50を示す。
The present invention will be described more specifically with reference to the following examples. However, the scope of the present invention is not limited to the following examples.
[Example 1: Tyrosinase activity inhibitory effect]
Mushroom tyrosinase was dissolved in 0.1 mol / L phosphate buffer so as to be 100 units / mL to prepare a tyrosinase solution. L-Dopa was similarly dissolved in 0.1 mol / L phosphate buffer to prepare a 0.1% L-Dopa solution. N-hydroxysuccinimide was added to a 0.1% L-Dopa solution kept at 37 ° C. at various concentrations (0 to 100 μg / mL), and then the tyrosinase solution was added. The average reaction rate at 37 ° C. at each concentration was calculated, and the concentration (IC 50 ) capable of 50% reaction inhibition was calculated from the obtained results, and the direct inhibitory effect of tyrosinase was evaluated. Moreover, IC 50 was calculated by the same method for arbutin and VC-PMg (ascorbic acid magnesium phosphate) known as tyrosinase activity inhibitors, and the results were compared. The calculated IC 50 is shown in Table 1 below.

表1に示した結果から、N−ヒドロキシコハク酸イミドは、直接、チロシナーゼに対して高い阻害効果を有し、優れたチロシナーゼ活性阻害剤であることが理解できる。   From the results shown in Table 1, it can be understood that N-hydroxysuccinimide directly has a high inhibitory effect on tyrosinase and is an excellent tyrosinase activity inhibitor.

[実施例2:メラニン産生抑制効果]
2枚の6穴のシャーレに培地を適量採取し、マウス由来B16メラノーマ細胞を播種し、37℃、二酸化炭素濃度5v/v%中にて静置する。翌日、各サンプルを最終濃度が適当な濃度となるように検体調製液を添加混和する。培養5日目に培地を交換し、再度検体調製液を添加する。翌日、培地を撤去し、1枚のシャーレについて細胞をリン酸緩衝液にて洗浄した後回収し、B16メラノーマ培養細胞の白色化度を以下の基準にて目視で評価した。
(判定基準)
++:対照に対して極めて白色である。
+:対照に対して明らかに白色である。
±:対照に対してやや白色である。
−:対照と同じ黒色である。
[Example 2: Inhibitory effect on melanin production]
A suitable amount of medium is collected in two 6-well petri dishes, seeded with mouse-derived B16 melanoma cells, and allowed to stand at 37 ° C. in a carbon dioxide concentration of 5 v / v%. The next day, the sample preparation solution is added and mixed so that each sample has an appropriate final concentration. On the fifth day of culture, the medium is changed and the sample preparation solution is added again. On the next day, the medium was removed, the cells were washed with a phosphate buffer in one petri dish, and then collected, and the degree of whitening of the cultured B16 melanoma cells was visually evaluated according to the following criteria.
(Criteria)
++: Extremely white relative to the control.
+: Clearly white relative to the control.
±: Slightly white with respect to the control.
-: The same black color as the control.

残りの1枚のシャーレについて、細胞をホルマリン固定後、1%クリスタルバイオレット溶液を添加し、染色した。各検体濃度に対する生存細胞数(A)及び対照の細胞数(B)をモノセルレータによって測定し、(A)/(B)%の比率により細胞生存率を算出した。また、上記目視による評価において、±以上の判定が得られた最小濃度(最小有効濃度)、及び細胞生育率が70%を下回る濃度(細胞毒性濃度)の値をそれぞれ求めた。メラニン産生抑制剤として公知のアルブチン及びVC−PMgについても同一の方法で最小有効濃度及び細胞生育率を算出し、結果を比較した。より低濃度で効果を発揮し(即ち、最小有効濃度が低く)、且つ細胞毒性濃度が高いものが使用にあたり望ましい。この観点より評価した。   For the remaining one petri dish, cells were fixed with formalin, and then a 1% crystal violet solution was added and stained. The number of viable cells (A) and the number of control cells (B) for each analyte concentration were measured with a monocellator, and the cell viability was calculated by the ratio of (A) / (B)%. In the visual evaluation, the minimum concentration (minimum effective concentration) at which a determination of ± or more was obtained and the concentration (cytotoxic concentration) at which the cell growth rate was less than 70% were determined. For arbutin and VC-PMg known as melanin production inhibitors, the minimum effective concentration and cell growth rate were calculated by the same method, and the results were compared. It is desirable for use to be effective at lower concentrations (ie, have a lower minimum effective concentration) and have higher cytotoxic concentrations. It evaluated from this viewpoint.

表2に示した結果から、N−ヒドロキシコハク酸イミドは、メラニン産生抑制効果が高く、しかも細胞毒性も低いので、従来公知のメラニン産生抑制剤と比較して、優れたメラニン産生抑制剤であることが理解できる。   From the results shown in Table 2, since N-hydroxysuccinimide has a high melanin production inhibitory effect and low cytotoxicity, it is an excellent melanin production inhibitor compared to conventionally known melanin production inhibitors. I understand that.
