【発明の詳細な説明】 ペプチド誘導体およびその製造法 五呪辺胃見 本発明は、高血圧治療剤もしくは低血圧治療剤等の循環機能改善剤、心・脳循環 疾患(たとえば心筋梗塞)の治療剤、腎疾患(たとえば急性腎不全)の治療剤等 、医薬として有用性が期待される新規なエンドセリン誘導体、その製造方法およ び該誘導体を主成分とする循環機能改善剤に関する。[Detailed description of the invention] Peptide derivatives and their production methods Gojube Stomach Viewing The present invention relates to a circulatory function improving agent such as a hypertension treatment agent or a hypotension treatment agent, and a cardiac/cerebral circulation agent. Treatment agents for diseases (e.g. myocardial infarction), renal diseases (e.g. acute renal failure), etc. , a novel endothelin derivative that is expected to be useful as a medicine, its production method, and and a circulatory function improving agent containing the derivative as a main component.

エンドセリン(ET)は、1988年、柳沢らによりブタ大動脈内皮細胞の培養 上清から単離・構造決定された21個のアミノ酸から成る血管収縮性ペプチドで ある(柳沢ら、ネイチャー(Nature)、 332巻。Endothelin (ET) was discovered in 1988 by Yanagisawa et al. in culture of porcine aortic endothelial cells. A vasoconstrictor peptide consisting of 21 amino acids whose structure was determined and isolated from the supernatant. There is (Yanagisawa et al., Nature, vol. 332).

It was revealed that there are peptides with a similar structure to endothelin. endothelin-1 (ET-]), endothelin-2ET-2), and endothelin-1 (ET-2), respectively. It is named docerin-3 (ET-3), and its structure is as follows.

Therefore, it is expected to be an endogenous factor involved in the regulation of the circulatory system, and is associated with hypertension. , cardiac and cerebral circulation diseases (e.g. myocardial infarction), and renal diseases (e.g. acute renal failure). It is estimated that the person in charge

上記ペプチドのアンタゴニストやアゴニストが得られれば本物質の作用機序の解 明に役立つのみならず、これらの疾患の有効な治療薬になる可能性が大きいと考 えられるが、現時点では、有効なエンドセリンのアンタゴニストが得られたとい う報告は見当たらない。If an antagonist or agonist of the above peptide is obtained, the mechanism of action of this substance will be elucidated. It is believed that this drug not only has the potential to be useful in treating these diseases, but also has great potential to become an effective treatment for these diseases. However, at present there is no evidence that an effective endothelin antagonist has been obtained. No reports were found.

またエンドセリンの活性を高めるような物質を見いだすことももう1つの課題で ある。Another challenge is to find substances that increase endothelin activity. be.

発明の要旨 本発明者らは、エンドセリンによる強力な血管平滑筋収縮活性を抑制もしくは増 強する作用を指標として鋭意研究しエンドセリンにおけるアミノ酸の置換による エンドセリン類似物の合成を行った結果、本発明の新規なエンドセリン誘導体に エンドセリンに対するアンタゴニスト(Antagonist)作用もしくはア ゴニスト(Agonist)作用のあることを見い出し本発明を完成した。Summary of the invention The present inventors have demonstrated that endothelin can suppress or increase the potent vascular smooth muscle contractile activity. We conducted extensive research using the strengthening effect as an indicator, and found that amino acid substitutions in endothelin As a result of synthesizing endothelin analogs, the novel endothelin derivative of the present invention was obtained. Antagonist effect or agonist on endothelin They discovered that it has an agonist effect and completed the present invention.

次にこのようにして得られた保護ペプチドまたは保護ペプチド樹脂を保護基脱離 反応に付す。該反応は、使用する保護基の種類によって異なるが、いずれにして もペプチド結合に影響を与えず一工程で全保護基が除かれることが工業的に有利 であり、従って、あらかじめ、保護基の採用は、その点を考慮して行われるが、 システィン含有ペプチドにおいては、2段階で、すなわち、まず、チオール保護 基以外の保護基を除去したのち、ついでチオール保護基を除去する方が、その精 製のしやすさから有利な場合もある。そのような場合に用いられるチオール保護 基としては、アセトアミドメチル基、3−ニトロ−2−ピリジンスルフェニル基 、トリメチルアセトアミドメチル基などが挙げられる。Next, the protected peptide or protected peptide resin obtained in this way is removed from the protecting group. Subject to reaction.

The deprotection reaction by acid treatment is generally carried out at an appropriate temperature of -20°C to 40°C. However, in acid treatment, anisole, phenol, thioanisole, m-cresol, p-cresol, dimethyl sulfide, l,4-butanedithio It is effective to add cation scavengers such as 2-ethane dithiol, 1, and 2-ethanedithiol. Ma In addition, thiol protecting groups that are stable to acid treatment, such as acetamidomethyl, 3-nitro Protecting groups such as -2-pyridinesulfenyl are iodine and mercury acetate for the former, and mercury acetate for the latter. , mercaptoethanol, etc. Also, histidine imidazole The 2,4-dinitrophenyl group used as the sol protecting group is treated with thiophenol. formyl, which is used as an indole protecting group for tryptophan. In the presence of the above-mentioned 1,2-ethanedithiol, 1,4-butanedithiol, etc. In addition to deprotection by acid treatment, alkali treatment with dilute sodium hydroxide, dilute ammonia, etc. It is also removed by potash treatment.
