Description

本発明は、小腸でのグルコ−ス及びガラクトースの吸収に関わるナトリウム依存性グルコ−ス共輸送体1(以下、適宜に「SGLT1」と略記する。)に特異的な阻害活性を有する4−イソプロピルフェニル グルシトール化合物に関する。   The present invention is 4-isopropyl having an inhibitory activity specific to sodium-dependent glucose cotransporter 1 (hereinafter abbreviated as “SGLT1” where appropriate) involved in the absorption of glucose and galactose in the small intestine. The present invention relates to a phenyl glucitol compound.

血糖値はメタボリックシンドロームのバイオマーカーの一つとなっており、空腹時血糖が126mg/dL以上を示すと糖尿病と診断される。また、空腹時血糖が正常であっても、食後2時間血糖値が140〜200mg/dLの場合には、耐糖能異常(又は食後高血糖)と診断される。近年の疫学的研究によれば、耐糖能異常が心血管障害のリスクを高めると報告されている(非特許文献1及び2参照)。さらに、運動療法や薬物治療を施すことで耐糖能異常から2型糖尿病への移行を抑制し、高血圧の発症も有意に抑制することが報告されている(非特許文献3参照)。   The blood glucose level is one of the biomarkers of metabolic syndrome, and diabetes is diagnosed when the fasting blood glucose level is 126 mg / dL or more. Even if fasting blood glucose is normal, a glucose tolerance abnormality (or postprandial hyperglycemia) is diagnosed when the blood glucose level for 2 hours after meal is 140 to 200 mg / dL. Recent epidemiological studies have reported that impaired glucose tolerance increases the risk of cardiovascular disorders (see Non-Patent Documents 1 and 2). Furthermore, it has been reported that exercise therapy and drug treatment suppress the transition from impaired glucose tolerance to type 2 diabetes and significantly suppress the onset of hypertension (see Non-Patent Document 3).

以上のことから、食後高血糖を抑制することが糖尿病やメタボリックシンドロームの発症抑制に重要であると考えられ、食後高血糖をコントロールする薬剤の需要が高まりつつある。   From the above, suppressing postprandial hyperglycemia is considered to be important for suppressing the onset of diabetes and metabolic syndrome, and the demand for drugs that control postprandial hyperglycemia is increasing.

従来、食後高血糖改善薬としては、糖類の加水分解酵素を阻害し、小腸からの糖の吸収を遅延させるα−グルコシダ−ゼ阻害剤が汎用されてきたが、新しい作用機序を有する食後高血糖改善薬の開発も行われている。   Conventionally, α-glucosidase inhibitors that inhibit saccharide hydrolase and delay sugar absorption from the small intestine have been widely used as postprandial hyperglycemia-improving drugs. Development of drugs to improve blood glucose is also underway.

哺乳動物の小腸上皮には高い頻度でナトリウム依存性グルコ−ス共輸送体1(SGLT1)が発現している。このSGLT1は小腸において、ナトリウムに依存し、グルコ−ス又はガラクト−スの能動輸送を司ることが知られている。そこで、SGLT1活性を阻害することによって、食事由来のグルコ−ス吸収を抑制し、食後高血糖の予防又は治療に用いることができる、ピラゾ−ル誘導体が報告されている(特許文献1〜6参照)。一方で、腎臓には高頻度にナトリウム依存性グルコ−ス共輸送体2(SGLT2)が発現しており、糸球体で一旦濾過されたグルコ−スはSGLT2を介して再吸収される(非特許文献4参照)。そして、SGLT2活性を阻害することによって、尿への糖***が促進され、血糖低下作用を示すことが報告されている(非特許文献5参照)。SGLT2阻害剤の特徴として、随時血糖を低下させる作用が優れているが、SGLT1阻害剤の様に食後高血糖を是正する作用は低い。また、SGLT1活性に加えて、SGLT2活性も同時に阻害するC−フェニル グルシトール誘導体についての報告もある(特許文献7参照)。   Sodium-dependent glucose cotransporter 1 (SGLT1) is frequently expressed in the small intestinal epithelium of mammals. SGLT1 is known to depend on sodium in the small intestine and to control the active transport of glucose or galactose. Thus, pyrazole derivatives that have been reported to inhibit SGLT1 activity to suppress dietary glucose absorption and to be used for the prevention or treatment of postprandial hyperglycemia (see Patent Documents 1 to 6). ). On the other hand, sodium-dependent glucose cotransporter 2 (SGLT2) is frequently expressed in the kidney, and glucose once filtered by the glomerulus is reabsorbed via SGLT2 (non-patent document). Reference 4). And it has been reported that the inhibition of SGLT2 activity promotes the excretion of sugar into urine and exhibits a blood glucose lowering effect (see Non-Patent Document 5). As a feature of SGLT2 inhibitor, it has an excellent effect of lowering blood glucose as needed, but it has a low effect of correcting postprandial hyperglycemia like SGLT1 inhibitor. There is also a report on a C-phenyl glucitol derivative that simultaneously inhibits SGLT2 activity in addition to SGLT1 activity (see Patent Document 7).

一方、食後高血糖改善薬のような持続投与が必要な薬剤にとっては、薬効量と、毒性、副作用の発現量との間の安全域が広いことが重要である。特に、体内残留性薬物の場合は、治療に必要な投与量をコントロールすることが難しく、体内に残留している薬物が加算されて過剰量の薬物の効果が発現されることになり、予期せぬ毒性及び副作用につながる。例えば、分子内に3級アミンの様な親水性基と芳香環の様な疎水性基をもつ、陽イオン性薬物は、リン脂質と疎水結合し、ライソゾーム内に取り込まれ全身の器官に蓄積されることがあることが知られている。代表例として、クロロキンでは網膜障害、パーヘキシリンでは肺や小脳に変化があり神経障害が問題となった(非特許文献6参照)。   On the other hand, for drugs that require continuous administration, such as postprandial hyperglycemic drugs, it is important that there is a wide safety range between the effective amount and the amount of toxicity and side effects. In particular, in the case of a drug remaining in the body, it is difficult to control the dose required for treatment, and the drug remaining in the body is added to express the effect of an excessive amount of drug. Cause toxic and side effects. For example, a cationic drug having a hydrophilic group such as a tertiary amine and a hydrophobic group such as an aromatic ring in the molecule is hydrophobically bound to a phospholipid, and is taken into a lysosome and accumulated in organs throughout the body. It is known that As typical examples, chloroquine caused retinal damage, and perhexiline had changes in the lungs and cerebellum, causing neuropathy (see Non-Patent Document 6).

したがって、薬物は、薬効を示した後に体内から速やかに***されることが望ましく、特に、持続投与が必須の食後高血糖改善薬では、体内残留性の問題のない薬物が望まれる。   Therefore, it is desirable that the drug is rapidly excreted from the body after exhibiting the drug effect. In particular, in the postprandial hyperglycemia improving drug for which continuous administration is essential, a drug having no problem of persistence in the body is desired.

The reaction mixture was cooled to room temperature, diluted with chloroform (300 mL) and methanol (100 mL), and filtered through celite. The filtrate was concentrated under reduced pressure, and the resulting residue was dissolved in ethyl acetate (1.32 L). It was washed with 1M hydrochloric acid (0.96 L), 10% brine (1.2 L), and dried over anhydrous magnesium sulfate. After the desiccant was filtered off, ethyl acetate (1.2 L) was further added to the filtrate, isopropylamine (28.2 mL, 0.327 mol) was added, and the mixture was stirred from room temperature to 0 ° C. for 1 hour. The deposited precipitate was filtered to obtain an isopropylamine salt of intermediate (1C-1). This salt was dissolved in ethyl acetate (1.2 L) and 1 M hydrochloric acid (500 mL) and stirred for 30 minutes, and the organic layer was separated. The organic layer was washed with 10% brine (500 mL) and dried over anhydrous magnesium sulfate. After filtering off the desiccant, the solvent was distilled off under reduced pressure to obtain an intermediate (1C-1) (207 g, 88%) as a colorless amorphous substance.
