Abstract
Description
本発明は、抗黴剤に関する。更に詳しくはクロカワカビ(Cladosporium cladosporioides)に有効な抗黴剤に関する。 The present invention relates to an antidepressant. More specifically, the present invention relates to an antidepressant effective against black mold (Cladosporium cladosporioides).
従来から、各種の工業製品に細菌、黴などの有害微生物が繁殖して、それらの品質や性能を低下させる問題があった。また、近年では密閉性の高い住居が増加することにより、生活環境中の黴が住居内で繁殖し、例えばエアコンディショナー使用中の黴臭など、さまざまな問題を起こしている。
そこで、例えば、食品の腐敗を防止するために、食品添加物として認められている安息香酸、ソルビン酸およびその塩などの合成保存料が使用されている。これらの合成保存料は、安全性や毒性的知見から、その使用をできるだけ抑制しようとする傾向にあるだけでなく、消費者側も、合成保存料に対して好ましいイメージを持たなくなってきた。これらの問題を解決すべく多くの天然物由来の抗菌、抗黴剤が開発されてきた。植物由来の精油には、抗菌抗黴性を有する化合物があり、それらを使用する試みも行われている。しかし、精油や精油成分の黴に対する最小発育阻止濃度は一般的に数百ppm以上であるため多量に用いなければならないこと、また、多くの精油や精油成分は特有の匂いを有するものが多く、ヒノキチオールなどは金属イオンとキレートを形成して着色する欠点などもあり、化粧品や食品などへの添加は現実的には難しいなどの課題を抱えている。
本発明が対象とする黴であるC.cladosporioidesはクロカワカビと呼ばれ、およそ60種類あるといわれている住宅に発生する黴の中で、最も検出率の高い黴の一つである。湿気の多いところを好み、水周り、冷蔵庫内、エアコンディショナーのフィルターなど、更に室内の湿度が高い住居においては、壁紙、カーペット、窓枠のゴムの部分などにも生える。また、アレルギー反応を引き起こす原因の一つとも言われている。
Conventionally, harmful microorganisms such as bacteria and sputum have propagated in various industrial products, and there has been a problem that their quality and performance are deteriorated. Further, in recent years, due to an increase in houses with high hermeticity, moths in the living environment have propagated in the house, causing various problems such as odors when using air conditioners.
Thus, for example, synthetic preservatives such as benzoic acid, sorbic acid and their salts, which are recognized as food additives, are used in order to prevent food from decay. These synthetic preservatives tend not only to suppress their use as much as possible from safety and toxicological findings, but also consumers have no favorable image for synthetic preservatives. In order to solve these problems, many antibacterial and antifungal agents derived from natural products have been developed. Plant-derived essential oils have compounds having antibacterial and antifungal properties, and attempts have been made to use them. However, the minimum growth inhibitory concentration of essential oils and essential oil components to straw is generally several hundred ppm or more, so it must be used in large amounts, and many essential oils and essential oil components often have unique odors, Hinokitiol has a drawback that it forms a chelate with a metal ion and is colored, and has a problem that it is practically difficult to add to cosmetics and foods.
C., which is the target of the present invention. clasporioides are called blackfish and are one of the highest detection rates among the moths that are said to have about 60 types. In places with high humidity, such as around water, in refrigerators, air conditioner filters, etc., it also grows on wallpaper, carpets, rubber parts of window frames, etc. It is also said to be one of the causes of allergic reactions.
本発明の抗黴剤の原料に係る、伽南香はベトナムおよびカンボジア地方で産出する沈香の一種で、伽羅と比較しても遜色の無い香気を有する香料物質である。伽南香の含有成分に関する研究報告のうち、伽南香のアセトン抽出から得た精油を分析した報告がある(非特許文献1)。そのなかで、本発明の2−(2−フェニルエチル)クロモンは伽南香精油の主要成分として報告されている。又、2−(2−フェニルエチル)クロモンの加熱型香料組成物に関する報告はあるが(特許文献1)、抗黴性に関する報告はない。
本発明は、天然物から得られる、特異な香気を有さない適用範囲の広い抗黴剤、特にクロカワカビに有効な抗黴剤を提供することを目的とする。 An object of the present invention is to provide an antifungal agent that is obtained from a natural product and has a wide range of applications that does not have a unique aroma, particularly an antifungal agent that is effective against black mold.
上記課題を解決するために鋭意検討した結果、伽南香精油の主要成分である2−(2−フェニルエチル)クロモンが、クロカワカビに対して強い抗黴性を有していることを発見し、本発明に到達した。すなわち、本発明は(1)で示される構造をもつ2−(2−フェニルエチル)クロモンを有効成分として含有することを特徴とするクロカワカビに有効な抗黴剤である。
以下、本発明を詳細に説明する。
本発明の2−(2−フェニルエチル)クロモンは、伽羅の一種である伽南香精油に含まれる成分である。又、これ以外に、ミカン科植物であるFlindersia laevicarpaから見いだされた報告がある。2−(2−フェニルエチル)クロモンはこれらから抽出して得ることができる。抽出溶媒としてはメタノール、エタノール、イソプロピルアルコールなどの低級アルコールや一般的な多価アルコール、アセトンやメチルエチルケトンなどのケトン類、メチルエーテルなどのエーテル類、酢酸エチルなどのエステル類などの一般的な有機溶剤が挙げられる。またこれ等の有機溶剤に抽出可能な程度に水が含まれていても良い。これらの抽出溶媒を用いた抽出液をそのまま使用しても良いが、一般的には溶剤を完全にあるいは適度に除去するのが望ましい。また、蒸留によって精油を得る方法もある。このようにして得た精油成分から、カラムクロマトグラフィーや高速液体クロマトグラフィーなどにより、2−(2−フェニルエチル)クロモンを分取、あるいはそれらの含有量を高めたものを使用しても良い。ただし、一般的に伽羅は稀少なうえ非常に高価であり上記の様な溶媒抽出法や蒸留法による手法は実用的でない。
Hereinafter, the present invention will be described in detail.
The 2- (2-phenylethyl) chromone of the present invention is a component contained in Shonan perfume essential oil, which is a kind of mandala. In addition to this, there is a report found from Flindersia laevicarpa which is a citrus family plant. 2- (2-Phenylethyl) chromone can be obtained by extraction from these. Extraction solvents include general organic solvents such as lower alcohols such as methanol, ethanol and isopropyl alcohol, general polyhydric alcohols, ketones such as acetone and methyl ethyl ketone, ethers such as methyl ether, and esters such as ethyl acetate. Is mentioned. Moreover, water may be contained to such an extent that the organic solvent can be extracted. Extracts using these extraction solvents may be used as they are, but in general, it is desirable to completely or moderately remove the solvent. There is also a method for obtaining essential oil by distillation. From the essential oil component obtained in this manner, 2- (2-phenylethyl) chromone may be fractionated by using column chromatography, high performance liquid chromatography, or the like, or those having higher contents may be used. However, in general, mandalas are rare and very expensive, and the above-described solvent extraction and distillation methods are not practical.
一方、化学合成により2−(2−フェニルエチル)クロモンを得ることもでき、この化学合成による方がはるかに実用的である。一般的な合成ルートは、フェニルプロピオン酸の酸ハロゲン化物と、2−ハイドロキシアセトフェノンからエステル体を得る。これを塩基性条件下で転位させ、酸性化で閉環して得ることができる。2−(2−フェニルエチル)クロモンはキレート性水酸基を有さないため着色の心配などはない。 On the other hand, 2- (2-phenylethyl) chromone can also be obtained by chemical synthesis, and this chemical synthesis is much more practical. A general synthetic route obtains an ester form from an acid halide of phenylpropionic acid and 2-hydroxyacetophenone. This can be obtained by rearrangement under basic conditions and ring closure by acidification. Since 2- (2-phenylethyl) chromone does not have a chelating hydroxyl group, there is no concern about coloring.
本発明の抗黴剤は2−(2−フェニルエチル)クロモンを必須成分とするが、既存の抗菌性を有する物質や、その他使用目的に応じて各種成分を任意に配合することができる。例えば食品に使用する場合に配合しうる成分としては、食品素材および食品添加物であればとくに限定されるものではない。また、化粧料に使用する場合には、通常化粧料に使用される成分であればとくに限定されるものではない。その他一般工業製品においても、該製品に悪影響を及ぼさない成分であれば任意に配合することができる。また、本発明の抗黴剤を香料などに含有させて用いることも可能である。
なお、抗黴剤中の有効成分である2−(2−フェニルエチル)クロモンの量は、例えば1〜100重量%の範囲で任意に配合でき特に限定されない。
Although the anti-epileptic agent of the present invention contains 2- (2-phenylethyl) chromone as an essential component, various components can be arbitrarily blended according to existing antibacterial substances and other purposes of use. For example, components that can be blended when used in foods are not particularly limited as long as they are food materials and food additives. Moreover, when using for cosmetics, if it is a component normally used for cosmetics, it will not specifically limit. Also in other general industrial products, any component that does not adversely affect the product can be arbitrarily blended. It is also possible to use the antifungal agent of the present invention by adding it to a fragrance or the like.
The amount of 2- (2-phenylethyl) chromone, which is an active ingredient in the antiepileptic agent, can be arbitrarily blended within a range of 1 to 100% by weight, for example, and is not particularly limited.
本発明の抗黴剤は、パン類、菓子類、麺類、乳製品類、惣菜類などの各種食品、ローション、乳液、クリームなどの基礎化粧料類、ハンドクリームなどの身体用化粧料類、洗顔料、ボディシャンプーなどの皮膚洗浄料類、シャンプー、リンスなどの頭髪用化粧料類、その他製品自体の黴の発生を防止することが必要なあらゆる製品に適用できる。また、浴室のタイルの目地や室内の壁紙やエアコンディショナーなどに本発明の抗黴剤を噴霧したりあるいは本発明の抗黴剤を含んだシート等を貼付することや、あるいは芳香剤などに含ませることにより、室内の黴発生を防止する抗黴性芳香剤なども本発明の適用範疇である。 The anti-wrinkle agent of the present invention includes various foods such as breads, confectionery, noodles, dairy products, side dishes, basic cosmetics such as lotions, milky lotions and creams, body cosmetics such as hand creams, and facial cleansers. It can be applied to skin cleansing materials such as cosmetics, body shampoos, hair cosmetics such as shampoos and rinses, and other products that are required to prevent wrinkling of the products themselves. In addition, spraying the antifungal agent of the present invention on bathroom tile joints, indoor wallpaper, air conditioners, etc., or sticking a sheet containing the antifungal agent of the present invention, or included in fragrances, etc. Thus, anti-deodorant fragrances that prevent generation of wrinkles in the room are also within the scope of application of the present invention.
本発明の2−(2−フェニルエチル)クロモンを有効成分とする抗黴剤の製品への配合量は任意に設定することができ、とくに限定されるものではないが、通常は、2−(2−フェニルエチル)クロモンの製品中の濃度が、10μg/g以上、好ましくは50〜10,000μg/gとなるように配合するのが望ましい。 The amount of the anti-epileptic agent containing 2- (2-phenylethyl) chromone of the present invention as an active ingredient can be arbitrarily set and is not particularly limited. It is desirable that the concentration of 2-phenylethyl) chromone in the product is 10 μg / g or more, preferably 50 to 10,000 μg / g.
本発明の2−(2−フェニルエチル)クロモンを有効成分として含有する抗黴剤は、ほぼ無臭であり、微量で優れた抗黴効果を示すものである。また、2−(2−フェニルエチル)クロモンはキレート性水酸基を有さないため着色の心配は低い。 The antifungal agent containing 2- (2-phenylethyl) chromone of the present invention as an active ingredient is almost odorless and exhibits an excellent antifungal effect in a small amount. Moreover, since 2- (2-phenylethyl) chromone does not have a chelating hydroxyl group, there is little concern about coloring.
以下、実施例により本発明をより詳細に説明するが、本発明はこれらに限定されるものではない。 EXAMPLES Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to these.

Production Example 1 (Production of 2- (2-phenylethyl) chromone)
DMF 150 mL, pyridine 40 mL and 2-hydroxyacetophenone 30 g were added to a four-necked colben equipped with a refluxer, and after homogenization, 43 g of 3-phenylpropionyl chloride was added dropwise while allowing the temperature to rise. Two hours after the completion of the dropwise addition, dilute hydrochloric acid was added to the reaction solution, followed by extraction with diisopropyl ether. The organic layer was washed with a 10% aqueous sodium carbonate solution and saturated brine in that order, and dried over anhydrous sodium sulfate. After the solvent was distilled off, the residue was purified by silica gel column chromatography (hexane: ethyl acetate = 9: 1) to obtain 55 g of an ester. Next, 9.2 g of sodium hydride (containing 60% oil) was added to 200 mL of THF at about 0 ° C. to homogenize, and the ester was slowly added dropwise. Two hours after the completion of the dropwise addition, dilute hydrochloric acid was added to the reaction solution, followed by extraction with diisopropyl ether. The organic layer was washed with saturated brine and dried over anhydrous sodium sulfate. The solvent was distilled off to obtain 57 g of a crude diketone body. Concentrated sulfuric acid 5mL and acetic acid 100mL were added to this diketone body 57g, and it heat-stirred at about 120 degreeC for 2 hours. Ice water was added to the reaction solution, and the mixture was extracted with diisopropyl ether. The organic layer was washed with a 10% aqueous sodium carbonate solution, a 10% aqueous sodium hydroxide solution and saturated brine in that order, and dried over anhydrous sodium sulfate. The crude crystals obtained by distilling off the solvent were purified by silica gel column chromatography (hexane: ethyl acetate = 3: 1) to obtain 43 g of almost odorless 2- (2-phenylethyl) chromone. It was confirmed by 1 H-NMR spectrum and GC-MS that this product was 2- (2-phenylethyl) chromone.

実施例1(抗黴性の評価)
製造例1で得た2−(2−フェニルエチル)クロモンについて、クロカワカビに対する最小発育阻止濃度(MIC)を日本化学療法学会標準法に準拠して測定した。
クロカワカビはポテトデキストロース寒天培地を用い、25℃で10日間培養した後、胞子浮遊液(107cfu/mL)を調整し試験菌液とした。3−メチル−4−イソプロピルフェノール(対照)、2−(2−フェニルエチル)クロモンは、それぞれ0.1gにジメチルスルホキサイド2mLを加えて溶解させた後、アセトン6mLを加え混和し、さらに滅菌精製水2mLを加えて混和させ1w/v%溶液を調整した。これら溶液を滅菌精製水で2段階希釈し試料溶液とした。
Example 1 (Evaluation of anti-eating properties)
With respect to 2- (2-phenylethyl) chromone obtained in Production Example 1, the minimum growth inhibitory concentration (MIC) against black mold was measured according to the Japanese Society of Chemotherapy Standard Method.
As for black mold, potato dextrose agar medium was cultured at 25 ° C. for 10 days, and then a spore suspension (10 7 cfu / mL) was prepared to obtain a test bacterial solution. 3-Methyl-4-isopropylphenol (control) and 2- (2-phenylethyl) chromone were dissolved by adding 2 mL of dimethyl sulfoxide to 0.1 g, respectively, and then adding 6 mL of acetone and mixing. 2 mL of purified water was added and mixed to prepare a 1 w / v% solution. These solutions were diluted in two stages with sterilized purified water to obtain sample solutions.
クロカワカビ用培地は、各試料溶液2mLにポリデキストロース寒天培地(日水製薬)18mLを加えて混和し、各試料溶液添加培地とした。
クロカワカビの試験菌液0.1mLを各試料溶液添加培地上に塗布しコンラージ棒にて広げ、25℃で7日間培養した。培養後、菌が阻止された培地中の最低試料濃度をMICとした。
この結果を表1に示す。この結果からクロカワカビに対するMICは、対照と同程度の60μg/mLであった。
The medium for black mold was added to 2 mL of each sample solution and mixed with 18 mL of polydextrose agar medium (Nissui Pharmaceutical) to prepare each sample solution added medium.
0.1 mL of the black mold fungus test solution was spread on each sample solution-added medium, spread with a conage bar, and cultured at 25 ° C. for 7 days. After the culture, the minimum sample concentration in the medium in which the bacteria were inhibited was defined as MIC.
The results are shown in Table 1. From this result, the MIC for black mold was 60 μg / mL, which was comparable to that of the control.
