Abstract
The present invention provides pharmaceutical compositions useful as agents for the inhibition of progression of diseases associated with abnormal accumulation of liver lipids. In particular, the pharmaceutical compositions of the present invention which comprise as an active ingredient a sodium/glucose co-transporter 2 inhibitor are highly suitable as an agent for the inhibition of progression of not only common fatty liver but also non-alcholic fatty liver disease (NAFL), non-alcholic steatohepatitis (NASH), hypernutritive fatty liver, diabetic fatty liver, alcholic fatty liver disease toxic fatty liver or the like.
Description
- The present invention relates to an agent for the inhibition of progression of diseases associated with abnormal accumulation of liver lipids, which comprises as an active ingredient a sodium/glucose co-transporter 2 (hereinafter referred to as SGLT2).
- The patients with disorders in which lipids are abnormally accumulated in liver, such as non-alcoholic steatohepatitis (NASH), hypernutritive fatty liver, diabetic fatty liver, alcoholic fatty liver, and toxic fatty liver as well as common fatty liver are increasing year by year. Above all, non-alcoholic steatohepatitis (NASH) is particularly acknowledged as a problem, because it exhibits serious symptoms (see non-Patent Reference 1 or 2). Moreover, it has been pointed out that abnormal lipid accumulation in liver causes liver inflammation or fibril formation in liver (liver cirrhosis) and makes shifts to serious disorders such as liver cancer (see non-Patent References 1 to 4), and thus, inhibiting this lipid accumulation is extremely important.
- It is believed that various factors including recent lifestyle changes overlap each other and abnormalities in liver energy metabolism are caused and as a consequence, lipid accumulation in liver occurs. Therefore therapeutic modality is not uniform (see non-Patent Reference 5). Although presently, dietary therapy, exercise therapy, pharmacotherapy and the like are tried as remedies for lipid accumulation in liver, these modalities have difficulties in control or continuing implementation. Therefore, therapeutic effects are not always satisfied. Meanwhile, in pharmacotherapy, polyene-phosphatidyl choline preparation is only listed under coverage. As described above, satisfied treatment modality for lipid accumulation in liver has not been established, and thus development of more effective drug for lipid accumulation has been desired.
- It is known that SGLT2 inhibitors are drugs which exhibit blood glucose-lowering action by inhibiting sugar reabsorption in kidney, and are useful as drugs for the prevention or treatment of diabetes mellitus (for example, see Patent References 1 to 19). In addition, as to SGLT2 inhibitor, it has been also proposed that concurrent use of T1095 represented by formula:
and a peroxisome proliferator-activated receptor (hereinafter referred to as PPAR) agonist or a retinoid X receptor (hereinafter referred to as RXR) agonist can suppress the onset of side effects such as fatty liver caused by PPAR agonists or RXR agonists, and therefore the dosage of PPAR agonist or RXR agonist can be reduced (see Patent Reference 20 or 21). However, it has not ever been known that SGLT2 inhibitors exhibit suppressive effects on abnormal accumulation of liver lipids as described in the present invention. - In the treatment of diabetic fatty liver, use of hypoglycemic agents has been studied (see non-Patent Reference 6). However, usefulness of diabetic drugs with blood glucose-lowering actions has been not confirmed, for example, it has been pointed out that tolbutamide does not exhibit suppressive effects on lipid accumulation in liver (see non-Patent Reference 7), and may adversely cause exacerbation of lipid accumulation in liver (see non-Patent Reference 6).
- In addition, it has been reported that clofibrate of an antihyperlipidemic agent causes lipid accumulation in liver as a side effect, while it lowers neutral fat or cholesterol in blood (see Patent Reference 22). Furthermore, it has been reported that microsomal triglyceride transfer protein (hereinafter referred to as MTP) inhibitor of an antihyperlipidemic agent causes lipid accumulation in liver, while it lowers neutral fat or cholesterol blood (See Patent References 23 and 24 and non-Patent References 8 and 9). As described above, in use of these antihyperlipidemic drugs, no correlation is observed in the amount of neutral fat or cholesterol between in blood and in liver, but induction of fatty liver is observed in some cases.

- For example, the above compounds can be prepared according to method described in the above Patent References 1 to 1.9 or an analogous method thereof.
- In the present invention, the term “disease associated with abnormal accumulation of liver lipids” means a disease wherein the lipids including triglyceride accumulate abnormally in liver, a disease wherein the ratio of the amount of lipids to healthy cells of the liver and the liver weight increase abnormally, and the size of the liver increases abnormally. A progressive type wherein the accumulative amount of lipids further increases is also included. Moreover, a disease that shifts to other diseases because of the accumulation of lipids, and a disease with inflammation are also included. Concretely besides common fatty liver, non-alcholic fatty liver disease (NAFL), non-alcholic steatohepatitis (NASH), hypernutritive fatty liver, alcholic fatty liver disease, toxic fatty liver, diabetic fatty liver, acute fatty liver of pregnancy and the like can be illustrated.
- The inhibitory effect on progression of the disease associated with abnormal accumulation of liver lipids can be confirmed by, for example, the examination that uses the KKAy mouse bearing the fatty liver. The present inventors confirmed that when 2-(4-methoxybenzyl)phenyl 6-O-ethoxycarbonyl-b-D-glucopyranoside of a SGLT2 inhibitor was orally administered to rat, the symptom that the lipid accumulative amount in rat liver increases is inhibited significantly in comparison with the case where the present compound is not administered. The above-mentioned result proves that a pharmaceutical composition comprising as an active ingredient a SGLT2 inhibitor is extremely useful as an agent for the inhibition of progression of a disease associated with abnormal accumulation of liver lipids.
- In the present invention, it is possible to use the SGLT2 inhibitor of the active ingredient optionally in combination with one or more other drugs used for the fatty liver. For example, polyenphosphatidyl choline preparation, daisaikoto and the like can be illustrated as other drugs that can be used in combination. In addition, as far as the purpose of the present invention can be achieved, the SGLT2 inhibitor can be used in combination with a drug other than the above-mentioned drugs. In the case, metformin, troglitazone, pioglitazone hydrochloride, bezafibrate, voglibose and the like are illustrated as examples of the other drugs.
- In the case of uses of the SGLT2 inhibitor in combination with the above one or more other drugs, either dosage form of simultaneous administration as a single preparation or separated preparations in way of the same or different administration route, and administration at different dosage intervals as separated preparations in way of the same or different administration route can be adopted.
- The pharmaceutical compositions of the present invention can be prepared by suitably admixing with or by diluting and dissolving with an appropriate pharmaceutical additive pharmaceutically used depending on the compositions or the dosage form such as excipients, disintegrators, binders, lubricants, diluents, buffers, isotonicities, antiseptics, moistening agents, emulsifiers, dispersing agents, stabilizing agents, dissolving aids and the like, by formulating the mixture in accordance with conventional methods in dosage forms such as powders, granules, fine granules, dry syrups, tablets, capsules, solutions, injections, ointments, suppositories, poultices and the like, which can be orally or parenterally administered. The pharmaceutical compositions of the present invention also include a sustained release formulation including gastrointestinal mucoadhesive formulation (see, for example, International publications Nos. WO99/10010 and WO99/26606, and Japanese patent publication No. 2001-2567).
- The dosage of a SGLT2 inhibitor in a pharmaceutical composition of the present invention is appropriately decided depending on the age, sex, body weight and degree of symptoms and treatment of each patient or the like, which is approximately within the range of from 0.1 to 1,000 mg per day per adult human in the case of oral administration and approximately within the range of from 0.0.1 to 300 mg per day per adult human in the case of parenteral administration. The daily dose can be divided into one to several doses per day and administered suitably. Also, in case of the uses of the drug(s) in combination with the other drug(s) other than SGLT2 inhibitors, the dosage of the SGLT2 inhibitor can be decreased depending on the dosage of the other drug(s) other than SGLT2 inhibitors.
- As mentioned above, the pharmaceutical compositions of the present invention which comprises as an active ingredient a SGLT2 inhibitor have an effect of the inhibition of progression of the disease associated with abnormal accumulation of liver lipids, and are highly suitable as an agent for the inhibition of progression of the disease associated with abnormal accumulation of liver lipids. Thence, the present invention can provide excellent pharmaceutical compositions that can inhibit the progression of the disease associated with abnormal accumulation of liver lipids by using a SGLT2 inhibitor without compelling patients the conventional dietary restriction by impossible diet therapy and the exercise therapy difficult to continue.
- The present invention is further illustrated in more detail by way of the following Example. However, the present invention is not limited thereto.
- Using KKAy mice (KKAy/Ta Jcl, CLEA Japan, Inc.) as experimental animals, inhibitory effects on accumulation of lipids in liver based on SGLT2 inhibitory effects were evaluated. KKAy mice bearing fatty liver were prepared as follows.
- Female 10-week-old KKAy mice were bred preparatorily for 4 weeks. During preparatory breeding until 4 days before grouping, the mice were fed on a pellet CE-2 diet for laboratory animal (CLEA Japan, Inc.) under free feeding. From 4 days before grouping, the food was changed to a powdered CE-2 diet for laboratory animal (CLEA Japan, Inc.). At the age of 14 weeks, body weight, blood glucose level and plasma alanine aminotransferase level (ALT) were measured for grouping. The mice were grouped (5 animals in each group) so that in any of these three laboratory values no significant difference was observed between the two groups. In the second group, the mice were fed on a powdered CE-2 diet for laboratory animal (CLEA Japan, Inc.) containing 1000 ppm of 2-(4-methoxybenzyl) phenyl 6-O-ethoxycarbonyl-β-D-glucopyranoside (hereinafter referred to as Compound A) as a SGLT2 inhibitor for 11 days, and then triglyceride contents in liver were measured. The results of the measurement were shown in Table 1. As, a consequence, it was demonstrated that lipid accumulation in liver was significantly suppressed by administration of Compound A to KKAy mice bearing fatty liver, compared to drug-untreated mice. This indicates that SGLT2 inhibitors exhibit inhibitory effects on the progression of diseases associated with by abnormal lipid accumulation in liver.
- Method of measurement of liver triglyceride content was described as follows.
- 1) Ice-cold saline (Otsuka Pharmaceutical Co., Ltd.) was added to liver in the proportion of 4 mL of ice-cold saline to 1 g of the liver, and then a homogenized suspension was prepared in a pestle homogenizer.
- 2) To 100 μL of the suspension 1), 800 μL of Folch reagent (chloroform:methanol=2:1) was added and mixed vigorously, and total lipids was extracted.
- 3) The mixture 2) was centrifuged (3000 rpm, for 1 min, at room temperature) using a cooled centrifuge (KUBOTA8900, KUBOTA Corporation).
- 4) The lower layer after centrifugation in 3) was collected and transferred to another containers and that is referred to as Solution (A).
- 5) To the upper layer after centrifugation in 3) 150 μUL of Folch reagent was added and mixed vigorously, and centrifugation by the operation identical to that in 3) was performed. The lower layer was added to the Solution (A) described above.
- 6) To the Solution (A) obtained in 5), 250 μL of saline was added and mixed vigorously, and centrifugation by the operation identical to that in 3) was performed again.
- 7) The upper layer after centrifugation in 6) was removed by suction, and the solvent of the lower layer was removed under a nitrogen flow.
- 8) The residue 7) was dissolved by adding of 300 μL of Folch reagent.
- 9) From the solution 8), 10 μL of that was transferred to a RIAbeads tube (Dainabot Co., Ltd.), and the solvent was removed under a nitrogen flow.
- 10) Triglyceride was measured in a reaction in which 1.5 mL of a coloring reagent of Triglyceride E-test Wako (Wako Pure Chemical Industries, Ltd.) was added to the residue 9).
- 11) The liver triglyceride content per gram was calculated from the results obtained in 10). The data were expressed as the mean ±standard error of the mean.
