Abstract

PROBLEM TO BE SOLVED: To obtain an agent for treating androgen disease such as alopecia, hirsuties, acne, prostatic hypertrophy or prostatic cancer by extracting components having strong inhibitory activity on 5αreductase from several kinds of crude medicines and compounding them as active components. SOLUTION: Diterpenes, obtained from several crude medicines such as SOKUHAKUYOU (leaf of Tsuja orientalis) and fritillaria bulb and having a trans diene configuration at carbons of 12, 14 positions of labdane structures, are used as active components. As the diterpenes. (E)6-hydroxy-8(17), 12,14- labdatriene18-acid, (E)8(17), 12,14-labdatriene-19-acid, (E)7-hydroxy-8(17), 12,14- labdatriene18-acid, (E)12,14-labdadiene-3, 8-diol, etc., are cited. A diterpene used here, e.g. 8(17), 12,14-labdatriene-19-acid is obtained by adding hexane to powder of SOKUHAKUYOU in an amount of about 5 times the powder of SOKUHAKUYOU, refluxing the hexane by heating, filtering the extraction mixture to collect a filtrate, subsequently removing the solvent by vacuum distrillation from the filtrate to obtain a residue and adding ethanol to the residue. Thus, the diterpenoid is obtained as an ethanol solution.

T) Overproduction of so-called androgenic diseases-acne, seborrhea, male pattern baldness (Male pattern)
Baldness or androgenetic alopecia andro
genetic alopecia), hirsutism, prostatic hypertrophy, prostate cancer, etc. are induced. This DHT is produced in the target organ by the reduction of androgens by 5α-reductase. Therefore, the development of anti-androgenic disease therapeutic agents using 5α-reductase inhibitors that alienate the activity of 5α-reductase has been vigorously carried out. This 5α-reductase inhibitor is roughly classified into two types, a steroid drug and a non-steroid drug. Among them, nonsteroidal drugs are not powerful and are still far from practical. Some steroidal 5α-reductases are being put to practical use. However, those with this skeleton cannot survive the side effects of steroid hormones. Severe side effects of this steroid type 5α-reductase inhibitor include infection, peptic ulcer, diabetes, psychiatric disorders, hypertension, withdrawal syndrome, adrenal insufficiency, etc.
There are hirsutism, menstrual abnormalities, edema, insomnia, osteoporosis, thrombosis, etc. Steroid therapy is used only under the supervision of a physician because the clinical effects and side effects are two sides of the same coin, and the minimum required dose to show clinical effects must be used and the side effects must always be kept in mind.

(17), 12,14-Labdatriene-19-carboxylic acid, for example, extracted and isolated and purified as follows. Approximately 5 times the amount of hexane is added to the powder of sokuhakuyou and heated to reflux. This is filtered and separated into a filtrate and a residue. The solvent of the filtrate is distilled off under reduced pressure, and the residue obtained is dissolved by adding 60% ethanol which is twice as much as the original sokuhaku. The portion remaining without being dissolved is removed by filtration, and the solid obtained by distilling off the solvent of the filtrate under reduced pressure is referred to as component A. The extraction / fractionation of the A component is not limited to the method described here, and for example, n
-Petroleum ether, petroleum benzine, benzene, etc. may be used instead of hexane. However, the described method is efficient and yields high. Component A is passed through a silica gel open column with a developing solvent of n-hexane: ethyl acetate, developed with TLC coated with silver nitrate to scrape the spot of the inhibitor, and passed through the silica gel open column again for purification to obtain a sample. The above is shown as a flowchart in Table 1.

For example, extraction, isolation and purification are performed as follows. Approximately 5 times the amount of hexane is added to the powder of sokuhakuyou and heated to reflux. This is filtered and separated into a filtrate and a residue. The solvent obtained by evaporating the solvent of the filtrate under reduced pressure was added to a residue obtained by adding twice the amount of
% Ethanol to dissolve. The portion remaining without being dissolved is removed by filtration, and the solid obtained by distilling off the solvent of the filtrate under reduced pressure is referred to as component A. The extraction and fractionation of the component A is not limited to the method described herein, and for example, petroleum ether, petroleum benzene, benzene, etc. may be used instead of n-hexane. However, the described method is efficient and yields high. Component A was passed through a silica gel open column with a developing solvent of n-hexane: ethyl acetate, developed by TLC coated with silver nitrate to scrape off spots of 5α-reductase inhibitor, and again purified. The sample is passed through a silica gel open column. The above is shown in Table 1 as a flowchart.

[0007] A 5α-reductase inhibitor was isolated and purified from the A component, and its structural analysis was attempted. The component A was passed through a silica gel column to isolate the substance having the strongest UV absorption. From the 1 H NMR spectrum, a quadruplet at δ6 to 7,
There are two triplet peaks at δ5 to 5.5, and two substances with similar structures having absorptions in triplet and quadruple pairs with integrated values of 0.7 and 1 are included. Therefore, each separation was attempted by preparative TLC coated with silver nitrate. Structural analysis was performed by 1 H and 13 C NM
As a result of measuring the R spectrum, mass spectrum, infrared absorption spectrum, ultraviolet absorption spectrum, and optical rotation,
