【発明の属する技術分野】
本発明は、高血圧症予防・改善・治療剤に関する。
【0002】
【従来の技術】
狭心症、心筋梗塞、心不全などの心疾患あるいは脳梗塞、脳出血、クモ膜下出血などの脳血管疾患は、高血圧と非常に深い関係があり、日本人の死因のそれぞれ第二位と第三位を占める。また、厚生省国民生活基礎調査(平成10年度)によれば、高血圧症で通院する患者数は我が国で千人あたり64人であり、病因の第一位を占めている。高血圧の対策としては、利尿薬、交感神経抑制薬、血管拡張薬、アンジオテンシン変換酵素阻害薬などの血圧降下医薬品が挙げられ、これらは主として重症高血圧患者に適用される。それに対して、食事療法、運動療法、飲酒・喫煙の制限などの生活習慣改善を目的とした一般療法は、軽症者から重症者までの高血圧者に広く適用されることから、一般療法の重要性が認識されている。なかでも食習慣の改善は重要であるといわれ、伝承として血圧降下効果作用を有すると言われる食品は数多く存在する。また従来から食品由来の血圧降下素材の探索が盛んに行われ、血圧降下作用を有する有効成分の分離・同定が数多くなされている。
【0003】
【発明が解決しようとする課題】
しかし、現状において高血圧症対策の目的で使用される医薬品は、有効性に関しては満足できるものが多い反面、少なからず存在する頻脈・徐脈等の副作用のため患者にかかる負担が大きい。また、血圧降下作用を有するといわれる食品あるいはその有効成分に関しても、その有効性には必ずしも満足できるものではなく、また血圧降下の効果が発現されるまでに長期間を要するものが多い。
従って、本発明の目的は、安全性に優れ、日常的な摂取にも負担にならず、且つより高い抗高血圧作用を有する高血圧症予防・改善・治療剤を提供することにある。
【0004】
【課題を解決するための手段】
本発明は、(a)カフェ酸、クロロゲン酸、フェルラ酸、それらのエステル及びそれらの薬学的に許容される塩の群から選ばれる化合物、(b)分子量60〜300の有機酸又はその薬学的に許容される塩を含有する高血圧症予防・改善・治療剤を提供するものである。
【0005】
【発明の実施の形態】

【0006】
カフェ酸、クロロゲン酸は、コーヒー生豆、南天の葉、リンゴ未熟果等の植物体から抽出したものでもよく、例えば、アカネ科コーヒー(Coffea arabica LINNE)の種子より、熱水抽出又は温時アスコルビン酸又はクエン酸酸性水溶液で抽出して得られたものが使用できる。
【0007】
フェルラ酸は、そのエステル体がコメあるいはハトムギ等の天然物、特に植物に含まれる化合物であり、植物からの精製物あるいは工業的に得られる合成品として得ることができる。フェルラ酸エステルは、例えば、コメの糠より得られた米糠油を、室温時弱アルカリ性下で含水エタノール及びヘキサンで分配した後、含水エタノール画分に得られる。フェルラ酸は、上記工程より得られたフェルラ酸エステルを加圧加熱下硫酸で加水分解し、精製して得るか、又は細菌(Pseudomonas)を、フトモモ科チョウジノキ(Syzygium aromaticum MERRILL et PERRY)のつぼみ及び葉より水蒸気蒸留で得られた丁子油、又は丁子油から精製して得られたオイゲノールを含む培養液で培養し、その培養液を、分離、精製して得ることができる。また、化学合成によってフェルラ酸を調製する場合は、例えば、バニリンとマロン酸との縮合反応によって製造することができる(Journal of American Chemical Society,74,5346,1952)。
【0008】
なお、カフェ酸、クロロゲン酸、フェルラ酸又はそれらの製剤学的に許容される塩には、立体異性体が存在し、本発明では、純粋な立体異性体又はそれらの混合物を用いることができる。
【0009】

【0010】
カフェ酸、クロロゲン酸、フェルラ酸を薬学的に許容される塩の形で用いることにより水溶性が向上し、生理学的有効性が増大する。これらの薬学的に許容される塩の塩形成用の塩基物質としては、例えば、アルカリ金属あるいはアルカリ土類金属の水酸化物、例えば、水酸化リチウム、水酸化ナトリウム、水酸化カリウム、水酸化マグネシウム、水酸化カルシウム、又は水酸化アンモニウムなどの無機塩基、アルギニン、リジン、ヒスチジン、オルニチンなどの塩基性のアミノ酸、又はモノエタノールアミン、ジエタノールアミン、トリエタノールアミンなどの有機塩基が用いられるが、特に好ましいものとして、アルカリ金属あるいはアルカリ土類金属の水酸化物が挙げられる。これらの塩を調製してから、その塩を本発明品中に添加してもよいし、塩形成成分を本発明品中に別々に添加して処方系中で反応させてもよい。
【0011】
本発明の成分(a)は、2種以上を併用してもよい。
【0012】

BACKGROUND OF THE INVENTION
The present invention relates to an agent for preventing / ameliorating / treating hypertension.
[0002]
[Prior art]
Heart diseases such as angina pectoris, myocardial infarction, heart failure or cerebrovascular diseases such as cerebral infarction, cerebral hemorrhage, and subarachnoid hemorrhage are very closely related to hypertension, and the second and third causes of death in Japan, respectively. Occupy a place According to the Ministry of Health and Welfare National Life Survey (1998), the number of patients with hypertension is 64 per thousand in Japan, accounting for the top of etiology. Antihypertensive measures include antihypertensive drugs such as diuretics, sympathomimetic drugs, vasodilators, angiotensin converting enzyme inhibitors, and these are mainly applied to patients with severe hypertension. On the other hand, general therapy aimed at improving lifestyle such as diet therapy, exercise therapy, restriction of drinking and smoking is widely applied to hypertensives from mild to severe, so the importance of general therapy Is recognized. In particular, improvement of eating habits is said to be important, and there are many foods that are said to have a blood pressure lowering effect as a tradition. In addition, food-derived blood pressure lowering materials have been actively searched for, and many active ingredients having blood pressure lowering effects have been separated and identified.
[0003]
[Problems to be solved by the invention]
However, many of the pharmaceuticals currently used for the purpose of antihypertensive measures are satisfactory in terms of effectiveness, but the burden on the patient is large due to side effects such as tachycardia and bradycardia that are not a few. In addition, foods that are said to have a blood pressure lowering effect or active ingredients thereof are not always satisfactory in their effectiveness, and many foods require a long period of time before the blood pressure lowering effect is manifested.
Accordingly, an object of the present invention is to provide an agent for preventing / ameliorating / treating hypertension which is excellent in safety, does not burden daily intake, and has a higher antihypertensive action.
[0004]
[Means for Solving the Problems]
The present invention relates to (a) a compound selected from the group of caffeic acid, chlorogenic acid, ferulic acid, esters thereof and pharmaceutically acceptable salts thereof, (b) an organic acid having a molecular weight of 60 to 300, or a pharmaceutical thereof The present invention provides a preventive, ameliorating, and therapeutic agent for hypertension, which contains a salt that is acceptable.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
As the component (a) used in the present invention, a natural product containing this, in particular, an extract of a plant can be used. Examples of the plant include coffee, onion, radish, lemon, morohaya, senkyu, touki, pine, Examples include auren, agi, sweet potato, corn, barley, and rice.
[0006]
Caffeic acid and chlorogenic acid may be extracted from plants such as green coffee beans, southern leaves, and unripe apples, for example, hot water extraction or warm ascorbine from the seeds of Coffea arabica LINNE. Those obtained by extraction with an acidic or citric acid aqueous solution can be used.
[0007]
Ferulic acid is a natural product such as rice or pearl barley, particularly a compound contained in plants, and can be obtained as a purified product from plants or a synthetic product obtained industrially. The ferulic acid ester is obtained, for example, in a water-containing ethanol fraction after partitioning rice bran oil obtained from rice bran with water-containing ethanol and hexane under mild alkalinity at room temperature. Ferulic acid is obtained by hydrolyzing and purifying the ferulic acid ester obtained from the above step with sulfuric acid under pressure and heating, or by obtaining bacteria (Pseudomonas) buds of Syzygium aromaticum MERRILL et PERRY and It can be obtained by culturing with clove oil obtained by steam distillation from leaves, or a culture solution containing eugenol obtained by purification from clove oil, and separating and purifying the culture solution. When ferulic acid is prepared by chemical synthesis, it can be produced, for example, by a condensation reaction of vanillin and malonic acid (Journal of American Chemical Society, 74, 5346, 1952).
[0008]
In addition, caffeic acid, chlorogenic acid, ferulic acid or a pharmaceutically acceptable salt thereof has a stereoisomer, and in the present invention, a pure stereoisomer or a mixture thereof can be used.

Like ferulic acid, esters corresponding to caffeic acid and chlorogenic acid are used.
[0010]
Use of caffeic acid, chlorogenic acid, and ferulic acid in the form of a pharmaceutically acceptable salt improves water solubility and increases physiological effectiveness. Examples of the basic substance for salt formation of these pharmaceutically acceptable salts include alkali metal or alkaline earth metal hydroxides such as lithium hydroxide, sodium hydroxide, potassium hydroxide, magnesium hydroxide. Inorganic bases such as calcium hydroxide or ammonium hydroxide, basic amino acids such as arginine, lysine, histidine, ornithine, or organic bases such as monoethanolamine, diethanolamine, and triethanolamine are used. As an alkali metal or alkaline earth metal hydroxide. After preparing these salts, the salts may be added to the product of the present invention, or the salt-forming components may be separately added to the product of the present invention and reacted in the formulation system.
