　本発明は、血糖低下等の作用を有し、糖尿病等の治療薬及び／又は予防薬として有用な新規な化合物及びその薬理上許容される塩に関する。 The present invention relates to a novel compound having an action such as lowering blood sugar and useful as a therapeutic and / or prophylactic agent for diabetes and the like and a pharmacologically acceptable salt thereof.
　本発明は、上記化合物又はその薬理上許容される塩を有効成分として含有する糖尿病（1型糖尿病、2型糖尿病、妊娠糖尿病等）、食後過血糖症、耐糖能障害、糖尿病性神経障害、糖尿病性腎症、糖尿病性網膜症、高脂血症、動脈硬化症、血栓性疾患、肥満、高血圧、浮腫、インスリン抵抗性、不安定糖尿病、インスリノーマ、高インスリン血症等の治療薬及び／又は予防薬（好適には糖尿病の治療薬及び／又は予防薬である）に関する。 The present invention includes diabetes (type 1 diabetes, type 2 diabetes, gestational diabetes, etc.), postprandial hyperglycemia, impaired glucose tolerance, diabetic neuropathy, diabetes containing the above compound or a pharmacologically acceptable salt thereof as an active ingredient Therapeutic and / or prevention for diabetic nephropathy, diabetic retinopathy, hyperlipidemia, arteriosclerosis, thrombotic disease, obesity, hypertension, edema, insulin resistance, unstable diabetes, insulinoma, hyperinsulinemia, etc. The present invention relates to a drug (preferably a therapeutic and / or preventive for diabetes).
　更に、本発明は、上記化合物又はその薬理上許容される塩を有効成分として含有する上記疾病の予防若しくは治療のための組成物、上記疾病の予防若しくは治療のための医薬を製造するための上記化合物の使用、又は上記化合物の薬理的な有効量を哺乳動物（好適には人間である）に投与する上記疾病の予防若しくは治療方法に関する。 Furthermore, the present invention provides a composition for preventing or treating the above-mentioned disease containing the above compound or a pharmacologically acceptable salt thereof as an active ingredient, and the above-mentioned pharmaceutical composition for producing a medicament for preventing or treating the above-mentioned disease. The present invention relates to the use of a compound, or a method for preventing or treating the above disease, wherein a pharmacologically effective amount of the above compound is administered to a mammal (preferably a human).
　糖尿病は、慢性的な高血糖を主徴とする疾患であり、インスリン作用の絶対的または相対的な不足により発症する。臨床においてはその特徴からインスリン依存性糖尿病（1型糖尿病）とインスリン非依存性糖尿病（2型糖尿病）に大別される。 Diabetes is a disease whose main feature is chronic hyperglycemia, and develops due to an absolute or relative lack of insulin action. In clinical practice, it is roughly divided into insulin-dependent diabetes (type 1 diabetes) and non-insulin-dependent diabetes (type 2 diabetes).
　現在、糖尿病の治療は基本的に食事療法と運動療法である。しかし、これらだけで血糖値をコントロールできなくなった場合、薬物が投与される。そこで、より安全で効果の高い薬剤が求められている。 Currently, diabetes treatment is basically diet therapy and exercise therapy. However, if the blood sugar level cannot be controlled by these alone, a drug is administered. Therefore, there is a demand for safer and more effective drugs.

（１）使用動物
　市販のマウス（C57BL/6Jマウス、雄、使用時8～12週齡、日本チャールス・リバー(株)販売）
（２）実験方法・結果
　マウスに飼料（FR-2、株式会社フナバシファーム）を1週間以上自由摂取させ予備飼育した後、一晩絶食し、試験に用いた。マウスへの投与液は、被験化合物の濃度を1 mg/mLとした0.5％メチルセルロース（和光純薬工業(株)）溶液(0.5％MC)、を調製した。調整した投与液を、各群4～5匹のマウスに対し、被検化合物の用量が10 mg/kgとなるように強制経口投与した。対照群は、0.5％メチルセルロース溶液（用量：10 mL/kg）を経口投与した。経口糖負荷は、被験化合物投与30分後にグルコース溶液（大塚糖液50％:(株)大塚製薬工業）を3g/kgの用量で経口投与して行った。 <Test Example 1> Oral glucose tolerance test (1) Animal used Commercially available mouse (C57BL / 6J mouse, male, 8-12 weeks old when used, sold by Charles River Japan Co., Ltd.)
(2) Experimental method / results Mice were allowed to freely ingest feed (FR-2, Funabashi Farm Co., Ltd.) for 1 week or longer and pre-bred, then fasted overnight and used for the test. As a liquid for administration to mice, a 0.5% methylcellulose (Wako Pure Chemical Industries, Ltd.) solution (0.5% MC) with a test compound concentration of 1 mg / mL was prepared. The prepared dosing solution was orally administered by gavage so that the dose of the test compound was 10 mg / kg to 4 to 5 mice in each group. In the control group, 0.5% methylcellulose solution (dose: 10 mL / kg) was orally administered. The oral glucose load was performed 30 minutes after administration of the test compound by oral administration of a glucose solution (Otsuka sugar solution 50%: Otsuka Pharmaceutical Co., Ltd.) at a dose of 3 g / kg.
　被験化合物投与直前（T0）、被験化合物投与25分後(T1)、経口糖負荷30分後(T2)および90分後(T3)に、マウスの尾静脈より採血を行い、血糖測定器（アキュチェックアビバ：ロシュ・ダイアグノスティックス（株））にて血糖値を測定した。また、T1血糖値は化合物投与30分後の糖負荷直前値として解析した。下記式より、血糖値曲線下面積を求め、対照群からの血糖低下率（％）を算出し、表２に示した。 Blood was collected from the tail vein of the mouse immediately before administration of the test compound (T0), 25 minutes after administration of the test compound (T1), 30 minutes after oral glucose load (T2) and 90 minutes (T3). Blood glucose level was measured with Check Aviva: Roche Diagnostics Co., Ltd. The T1 blood glucose level was analyzed as the value immediately before glucose load 30 minutes after compound administration. The area under the blood glucose level curve was determined from the following formula, and the blood glucose reduction rate (%) from the control group was calculated.
　血糖値曲線下面積＝[（T0血糖値＋T1血糖値）×30]÷2 ＋[（T1血糖値＋T2血糖値）×30]÷2 ＋[（T2血糖値＋T3血糖値）×60]÷2
　血糖低下率（％）＝[１－(被験化合物投与群血糖値曲線下面積／対照群血糖値曲線下面積)]×100  Area under the blood glucose level curve = [(T0 blood sugar level + T1 blood sugar level) x 30] + 2 + [(T1 blood sugar level + T2 blood sugar level) x 30] / 2 + [(T2 blood sugar level + T3 blood sugar level) x 60] / 2
Blood glucose reduction rate (%) = [1- (Area under test compound administration group blood glucose level curve / Area under control group blood glucose level curve)] × 100

　ラットに飼料（F-2、株式会社フナバシファーム）を2週間自由摂取させ予備飼育した後、一晩絶食し、試験に用いた。ラットへの投与液は、被験化合物の濃度を2.5 mg/mLとした0.5％メチルセルロース（和光純薬工業(株)）溶液(0.5％MC)を調製した。調製した投与液を、各群5匹のラットに対し、被検化合物の用量が10 mg/kgとなるように強制経口投与した。対照群は、0.5％メチルセルロース溶液（用量：4 mL/kg）を経口投与した。経口糖負荷は、被験化合物投与30分後にグルコース溶液（大塚糖液50％:(株)大塚製薬工業）を2.5g/kgの用量で経口投与して行った。 <Test Example 2> Oral glucose tolerance test (1) Animal used Commercially available rat (Zucker fatty rat, male, 9 weeks old when used, sold by Nippon Charles River Co., Ltd.)
(2) Experimental methods and results Rats were allowed to freely take a feed (F-2, Funabashi Farm Co., Ltd.) for 2 weeks, preliminarily bred, then fasted overnight and used for the test. As a solution for administration to rats, a 0.5% methylcellulose (Wako Pure Chemical Industries, Ltd.) solution (0.5% MC) with a test compound concentration of 2.5 mg / mL was prepared. The prepared dosing solution was forcibly orally administered to 5 rats in each group so that the test compound dose was 10 mg / kg. In the control group, 0.5% methylcellulose solution (dose: 4 mL / kg) was orally administered. The oral glucose load was performed 30 minutes after administration of the test compound by orally administering a glucose solution (Otsuka sugar solution 50%: Otsuka Pharmaceutical Co., Ltd.) at a dose of 2.5 g / kg.
　被験化合物投与直前（T0）、被験化合物投与25分後(T1)、経口糖負荷30分後(T2)、60分後(T3)、120分後(T4)および180分後(T5)に、ラットの尾静脈より採血を行い、血糖測定器（アキュチェックアビバ：ロシュ・ダイアグノスティックス（株））にて血糖値を測定した。また、T1血糖値は化合物投与30分後の糖負荷直前値として解析した。下記式より、血糖値曲線下面積を求め、対照群からの血糖低下率（％）を算出し、表３に示した。 Immediately before test compound administration (T0), 25 minutes after test compound administration (T1), 30 minutes after oral glucose load (T2), 60 minutes (T3), 120 minutes (T4) and 180 minutes (T5), Blood was collected from the tail vein of the rat, and the blood glucose level was measured with a blood glucose meter (Accu Check Aviva: Roche Diagnostics Co., Ltd.). The T1 blood glucose level was analyzed as the value immediately before glucose load 30 minutes after compound administration. From the following formula, the area under the blood glucose level curve was determined, and the blood glucose reduction rate (%) from the control group was calculated.
　血糖値曲線下面積＝[（T0血糖値＋T1血糖値）×30]÷2 ＋[（T1血糖値＋T2血糖値）×30]÷2 ＋[（T2血糖値＋T3血糖値）×30]÷2 ＋[（T3血糖値＋T4血糖値）×60]÷2 ＋[（T4血糖値＋T5血糖値）×60]÷2
　血糖低下率（％）＝[１－(被験化合物投与群血糖値曲線下面積／対照群血糖値曲線下面積)]×100 Area under the blood glucose curve = [(T0 blood sugar level + T1 blood sugar level) x 30] ÷ 2 + [(T1 blood sugar level + T2 blood sugar level) x 30] ÷ 2 + [(T2 blood sugar level + T3 blood sugar level) x 30] ÷ 2 + [(T3 blood glucose level + T4 blood glucose level) × 60] ÷ 2 + [((T4 blood glucose level + T5 blood glucose level) × 60] ÷ 2
Blood glucose reduction rate (%) = [1- (Area under test compound administration group blood glucose level curve / Area under control group blood glucose level curve)] × 100
