【発明の属する技術分野】
本発明は、テストステロンの活性発現を阻害することにより、男性ホルモン依存性疾患である前立腺肥大症,前立腺腫瘍,少年の思春期早期発現症,尋常性ざ瘡,脂漏等の治療,改善に有効な抗アンドロゲン剤、及び男性型脱毛症の予防,改善に有効な養毛剤及び毛髪用化粧料に関する。
【0002】
さらに詳しくは、テルペン類であるメチルジヒドロイソジャスモネイト( methyl dihydroisojasmonate ),メチルジヒドロジャスモネイト( methyl dihydrojasmonate )より選ばれる1種又は2種を含有して成る、抗アンドロゲン剤、養毛剤及び毛髪用化粧料に関する。
【0003】
【従来の技術】
男性ホルモンであるテストステロンに依存性の前立腺肥大症,前立腺腫瘍,少年の思春期早期発現症,尋常性ざ瘡,脂漏といった疾患に対して、従来より抗アンドロゲン作用を有する薬剤が用いられてきた。かかる抗アンドロゲン剤としては、酢酸シプロテロンが代表的なものとして挙げられる。この酢酸シプロテロンは、活性型テストステロンであるジヒドロテストステロンの受容体への結合を競合的に阻害するといわれている。
【0004】
また、男性型脱毛症の改善及び防止には、2,4−ジアミノ−6−ピペリジノピリミジン−3−オキシド(ミノキシジル),セファランチン,ビタミンE誘導体,塩化カルプロニウムといった血行促進作用を有するもの、アデノシン三リン酸,ウロガストロン,バイカレイン,パンテテイン−S−スルホン酸,奇数鎖脂肪酸誘導体といった毛母細胞賦活作用を有するものが主に用いられてきた。
【0005】
さらに、男性型脱毛症がテストステロン依存性であることから、テストステロンを活性型のジヒドロテストステロンに変換する酵素であるテストステロン5α−リダクターゼを阻害する物質の検討が主としてなされてきた。かかる阻害剤としては、アンドロスタノン誘導体,ビシクロヘプテノン誘導体,フェノキシブタン誘導体,トコフェリルキノン,トロポロン誘導体,ユビキノン等の他、シソ科植物,キク科植物をはじめ多くの植物の抽出物が知られている。
【0006】
しかしながら、上記の抗アンドロゲン剤,血行促進剤,毛母細胞賦活剤或いはテストステロン5α−リダクターゼ阻害剤の多くは、副作用の発現が懸念されたり、製剤基剤中での安定性が悪かったり、作用が不十分であったりして、十分な抗アンドロゲン活性と安定性及び安全性を充足するものは少なかった。また、植物を基原とするものについては、一定の品質のものを得るのが困難で、さらに製剤に際し好ましくない色や臭いを有するものも多かった。
【0007】
【発明が解決しようとする課題】
従って本発明においては、高い抗アンドロゲン作用を有し、少量の使用でテストステロン依存性疾患を有効に治療,改善することができ、しかも安定性が良好で、副作用がなく安全性にも優れる抗アンドロゲン剤を提供することを目的とした。また、テストステロン依存性の男性型脱毛症を有効に予防,改善し得る養毛剤及び毛髪用化粧料を得ることをも目的とした。
【0008】
【課題を解決するための手段】
上記の課題を解決するに当たり、本発明者らは植物精油中のテルペン類に着目した。すでに植物精油中より、イソピペリテノン,カルボン,ピペリテノンといった、育毛,養毛活性を有するモノテルペン性ケトンが単離されているが、今回新たにジャスミン精油中に含まれる4種のテルペンが非常に優れた抗アンドロゲン作用を有することを見い出し、本発明を完成するに至った。
【0009】
すなわち本発明においては、化学式(2)で表されるメチルジヒドロイソジャスモネイト( methyldihydroisojasmonate ),化学式(3)で表されるメチルジヒドロジャスモネイト( methyl dihydrojasmonate より選ばれる1種又は2種を、アルコール等の担体や製剤基剤中に含有させる。

【0011】
なお、シス−ジャスモンについては100μM(16.4μg/ml)、メチルジヒドロイソジャスモネイトについては20μM(4.5μg/ml)、メチルジヒドロジャスモネイトについては40μM(9.0μg/ml)、ジヒドロジャスモンについては200μM(33.2μg/ml)程度で十分な抗アンドロゲン効果を得ることができる。
【0012】
【作用】
本発明において有効成分として用いるシス−ジャスモン,メチルジヒドロイソジャスモネイト,メチルジヒドロジャスモネイト及びジヒドロジャスモンは、高い抗アンドロゲン作用を示す。この作用は、これらがシクロアルカン又はシクロアルケン構造を有することから、ジヒドロテストステロンの受容体に対する結合を競合的に阻害することによるものと考えられる。
【0013】
従って、本発明に係る抗アンドロゲン剤は、前立腺肥大症,前立腺腫瘍,少年の思春期早期発現症,尋常性ざ瘡,脂漏といったテストステロン依存性疾患に対し、優れた治療,改善効果を示す。また、本発明に係る養毛剤及び毛髪用化粧料は、テストステロン依存性の男性型脱毛症を良好に予防,改善する。

TECHNICAL FIELD OF THE INVENTION
INDUSTRIAL APPLICABILITY The present invention is effective for the treatment and improvement of androgen-dependent diseases such as prostatic hypertrophy, prostatic tumor, early puberty in boys, acne vulgaris, seborrhea, etc. by inhibiting the expression of testosterone activity. The present invention relates to a novel antiandrogen, a hair restorer and a hair cosmetic effective for preventing and improving male pattern baldness.
[0002]
More particularly, methyl dihydro iso jasmonate Nate is terpenes (methyl dihydroisojasmonate), comprising one or two selected from methyl dihydrojasmonate Nate (methyl dihydrojasmonate), antiandrogens, for hair tonics and hair Related to cosmetics.
[0003]
[Prior art]
Drugs with antiandrogenic activity have been used for diseases such as prostatic hypertrophy, prostatic tumor, early puberty in boys, acne vulgaris, and seborrhea that are dependent on the male hormone testosterone. . A typical example of such an anti-androgen is cyproterone acetate. This cyproterone acetate is said to competitively inhibit the binding of dihydrotestosterone, an active testosterone, to the receptor.
[0004]
For improving and preventing male pattern baldness, those having a blood circulation promoting action such as 2,4-diamino-6-piperidinopyrimidine-3-oxide (minoxidil), cepharanthin, vitamin E derivatives, carpronium chloride, and adenosine Those having a hair matrix activating action such as triphosphate, urogastron, baicalein, pantethein-S-sulfonic acid, and odd-chain fatty acid derivatives have been mainly used.
[0005]
Furthermore, since male pattern baldness is testosterone-dependent, substances that inhibit testosterone 5α-reductase, an enzyme that converts testosterone to active dihydrotestosterone, have been mainly studied. As such inhibitors, in addition to androstanone derivatives, bicycloheptenone derivatives, phenoxybutane derivatives, tocopherylquinones, tropolone derivatives, ubiquinones and the like, extracts of many plants including Lamiaceae and Asteraceae are known. I have.
[0006]
However, many of the above-mentioned antiandrogens, blood circulation promoters, hair cell activators or testosterone 5α-reductase inhibitors are concerned about the occurrence of side effects, have poor stability in the formulation base, or have an effect. There were few that were insufficient or sufficient antiandrogenic activity and stability and safety. In addition, it is difficult to obtain a plant-based product having a certain quality, and many of the products have an unfavorable color or odor when prepared.
[0007]
[Problems to be solved by the invention]
Therefore, in the present invention, an anti-androgen having high anti-androgen activity, capable of effectively treating and improving testosterone-dependent diseases with a small amount of use, and having good stability, no side effects and excellent safety. It was intended to provide an agent. Another object of the present invention is to provide a hair restorer and a hair cosmetic which can effectively prevent and improve testosterone-dependent male pattern baldness.
[0008]
[Means for Solving the Problems]
In solving the above problems, the present inventors focused on terpenes in plant essential oils. Monoterpene ketones having hair growth and hair growth activities, such as isopiperitenone, carvone, and piperitenone, have been isolated from plant essential oils. The four terpenes newly contained in the essential oils of jasmine are very excellent. The inventors have found that they have an anti-androgen action, and have completed the present invention.
[0009]
That is, in the present invention include methyl dihydroisoquinoline jasmonate Nate represented by the chemical formula (2) (methyldihydroisojasmonate), one or two selected from methyl dihydrojasmonate Nate represented by the chemical formula (3) (methyl dihydrojasmonate) , Alcohol or the like or a formulation base.

Cis-jasmon and the like are dissolved or dispersed in liquid carriers such as ethanol, propylene glycol, dipropylene glycol, glycerin, 1,3-butylene glycol, and squalane, semi-solid carriers such as liquid paraffin, and solid carriers such as petrolatum, and It is encapsulated in capsules or contained in pharmaceutical bases such as gels and emulsions and cosmetic bases.
[0011]
In addition, 100 μM (16.4 μg / ml) for cis-jasmon, 20 μM (4.5 μg / ml) for methyldihydroisojasmonate, 40 μM (9.0 μg / ml) for methyldihydrojasmonate, About 200 μM (33.2 μg / ml) of Jasmon can provide a sufficient anti-androgen effect.
[0012]
[Action]
Cis-jasmon, methyldihydroisojasmonate, methyldihydrojasmonate and dihydrojasmon used as active ingredients in the present invention exhibit high antiandrogenic activity. This action is thought to be due to competitive inhibition of dihydrotestosterone binding to the receptor since they have a cycloalkane or cycloalkene structure.
[0013]
Therefore, the anti-androgen agent according to the present invention exhibits excellent therapeutic and ameliorating effects on testosterone-dependent diseases such as benign prostatic hyperplasia, prostate tumor, early puberty in juveniles, acne vulgaris, and seborrhea. Further, the hair restorer and the hair cosmetic composition according to the present invention favorably prevent and improve testosterone-dependent male pattern baldness.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention can be provided in the form of a lotion, emulsion, gel, cream, ointment and the like. In addition, it can be provided as a hair restorer and a hair cosmetic in the form of hair lotion, hair tonic, hair milk, hair gel, hair cream, hair pack, hair treatment, hair shampoo, hair rinse and the like.
[0015]
【Example】
Further, the present invention will be described in detail with reference to examples.
[0016]
Cis-jasmon, methyldihydroisojasmonate, methyldihydrojasmonate and dihydrojasmon were added to an aqueous base comprising an aqueous solution containing 10.0% by weight of ethanol and 1.0% by weight of hydroxyethylcellulose in the concentration shown in Table 1. Thus, anti-androgens were prepared so as to be as follows.
[Table 1]
Figure 0003568325
[0017]
The antiandrogenic effects of Examples 1 to 4 were evaluated using spontaneous mouse breast cancer cells and the SC-3 cell line showing androgen-dependent growth. SC-3 cells were detached by treatment with 0.125% by weight of trypsin, dispersed in MEM medium supplemented with 2% by weight of fetal calf serum (FCS), and dispersed in 96 wells at a cell density of 1.0 × 10 4 cells / well. Seeded on microplate. After 24 hours, the medium was replaced with a sample or a test serum-free medium (Ham's F-12 + MEM (1: 1) + 0.5% by weight bovine serum albumin) supplemented with the sample and 10 −8 M dihydrotestosterone, After culturing for 48 hours, the medium was replaced with a 2% by weight FCS-supplemented MEM medium containing 0.4 mg of 2- (4,5-dimethyl-2-thiazolyl) -3,5-diphenyltetrazolium bromide (MTT). After culturing for 2 hours, the produced formazan was determined from the difference in absorbance at 550 nm and 650 nm. Assuming that the amount of formazan produced by SC-3 cells when dihydrotestosterone and the sample were not added was 100, the amount of formazan produced (MTT index) when dihydrotestosterone was added and when the sample was further added was determined. The inhibition rate of dihydrotestosterone-dependent growth was determined. In the equation (1), MTT · I DHT , MTT · I C, MTT index value at MTT · I S each dihydrotestosterone 10 -8 M addition, control of MTT index value, MTT index value at sample application Is shown. The results are shown in Table 1.
(Equation 1)
