技術分野 Technical field
本発明は血糖及び血中脂質低下作用を有する新規チアゾリ ジンジオン 绣導体,その製造法およびそれを含んでなる医薬組成物に関する。  The present invention relates to a novel thiazolidinedione conductor having a blood glucose and blood lipid lowering action, a method for producing the same, and a pharmaceutical composition comprising the same.
背景技術 Background art
従来より、 糖尿病治療剤として種々のビグアナィ ド系化合物およびス ルホニルゥレア系化合物が用いられている。 しかし、 ビグアナイ ド系化 合物は乳酸アシ ドーシスを引き起こすため、 現在ほとんど用いられてお らず、 またスルホニルゥ レア系化合物は強力な血糖低下作用を有するが しばしば重篤な低血糖を引き起し、 使用上の注意が必要でこのような欠 点のない新しい糖尿病治療薬の出現が望まれている。 一方、 日本公開特 許公報昭 5 5— 2 2 6 3 6 ,昭 5 5— 64 5 8 6.Chemical &  Conventionally, various biguanide compounds and sulfonyl perrea compounds have been used as therapeutic agents for diabetes. However, biguanide compounds cause little lactic acidosis and are rarely used at present. There is a demand for a new antidiabetic drug that requires careful use and does not have such disadvantages. On the other hand, Japanese published patent gazettes 55-222 636, 55-64 5 8 6.
Pharmaceutical Bulletin, 3 0巻, P.3563(1982) ,同誌, 3 0巻, P.Pharmaceutical Bulletin, Vol. 30, P.3563 (1982), Journal, Vol. 30, P.
3580(1982), 及び同誌, 3 2巻, P.2267(1984)には、種々のチアゾリ ジン ジオン類が血中脂質及び血糖低下作用を示すことが記載され、 さらには Diabetes, 3 2巻, P.804(1983)には cigl itazone の抗糖尿病作用につ いての記載があるが、 これらはいずれも糖尿病治療薬として実用化され るには至っていない。 本発明者らはチアゾリ ジンジオン類についてさら に研究を重ねた結果、 既知化合物に比して非常に強力な血糖及び血中脂 質低下作用を有し、 高い治療効果の期待できる全く新規な誘導体を見出 発明の開示 3580 (1982), and the same journal, Vol. 32, p. 2267 (1984), describe that various thiazolidinediones show blood lipid and blood glucose lowering effects. Further, Diabetes, Vol. P.804 (1983) describes the anti-diabetic effect of cigl itazone, but none of them has been put to practical use as a therapeutic drug for diabetes. The present inventors have conducted further studies on thiazolidinediones, and as a result, have found a completely novel derivative that has a very potent blood glucose and blood lipid lowering effect as compared with known compounds and can be expected to have a high therapeutic effect.

波検化-合物を粉末飼料(C E— 2 ,日本クレア)に 0.001%および 0.005 %混合し、 KKA7—マウス(雄性, 8〜 1 0週令, 1群 5匹)に自由に 4 日間与えた。 この間水は自由に与えた。 血液を眼窩静脈そうから採取し、 血糖値をグルコースォキシダーゼ法により、 また血漿トリグリセリ ド(T G)値は酵素法により生成するグリセロールを Cleantech TG- Sキッ ト(ャ ト口ン)を用いて定量することによりそれぞれ測定した。 それぞれの値 は下式を用いて計算した。 結果を表 1 3に示す。 比较のため構造類似の 既知化合物についてのデータ も併記する。  Wave test-mixed with powdered feed (CE-2, CLEA Japan) 0.001% and 0.005%, and given to KKA7 mice (male, 8-10 weeks old, 5 mice per group) for 4 days Was. Water was provided ad libitum during this time. Blood is collected from the orbital vein, blood glucose is determined by the glucose oxidase method, and plasma triglyceride (TG) is quantified by enzymatic method using the glycerol produced by the enzymatic method using a Cleantech TG-S kit. Each was measured. Each value was calculated using the following equation. Table 13 shows the results. Data for known compounds with similar structures are also shown for comparison.
