and R

Rosiglitazone exhibits a moderate blood sugar-lowering effect, but has little activity versus hyperlipidemia, which is common in patients with diabetes. Furthermore, because its half life is short in terms of pharmacodynamics, it must be inconveniently administered twice a day. In rare cases, it has been clinically reported that liver toxicity involved in use of rosiglitazone drugs causes death. Therefore, there is a disadvantage in that the patients with diabetes must have their liver function tested periodically.

DISCLOSURE OF THE INVENTION

Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a new thiazolidinedione based compound having activities such as strong blood sugar lowering action and strong blood lipid lowering action, compared with rosiglitazone, and a pharmaceutical composition containing the thiazolidinedione based compound.

It is another object of the present invention to provide a new thiazolidinedione based compound, in which its half-life is remarkably prolonged, and a pharmaceutical composition containing the thiazolidinedione based compound.

It is yet another object of the present invention to provide a new thiazolidinedione based compound, in which liver toxicity, a common side effect encountered with this type of compound drug, is not found, and a pharmaceutical composition containing the thiazolidinedione based compound.

BEST MODE FOR CARRYING OUT THE INVENTION

To overcome disadvantages of rosiglitazone described above, the inventors have researched documents concerning thiazolidinedione based compounds for several years. At the same time, they have studied the relationship of the thiazolidinedione based drug and its receptor using computer-aided molecular design.

According to the X-ray crystal structure of a PPARγ (peroxisome proliferator activated receptor), a molecule that influences insulin resistance, it has been found that part of the lipophilic tail thereof consists of hydrophobic residues such as isoleucine, valine, leucine, etc. Also, the size of active site thereof is very large, and the length and volume of the site are sufficient for about two hexagonal aromatic rings to be introduced into the site. Based on these facts, the inventors made an every efforts to develop new drugs with excellent functional groups, binding strongly with the PPARγ, a molecule that influences insulin resistance. As a result, they induced a substituted or unsubstituted aryl structure, i.e. a substituted or unsubstituted pyridine or pyrimidine, in which a nitrogen, an oxygen or a sulfur atom is incorporated at the para position of the first nitrogen of the pyridine or pyrimidine, i.e., at the 4 position. By preparing a thiazolidinedione based compound containing the aryl structure in the laboratory and then assaying its pharmacological toxicity, the present inventors have found it to be a new and excellent thiazolidinedione derivative for treatment of diabetes.

In terms of the structure of rosiglitazone of formula (2) above compared with the present invention of the formula (1), A

1

in the formula (2) is pyrimidine or pyridine, which corresponds to the pyrimidine (X═N) or pyridine (X═C) of the formula (1). As for the pyrimidine, an amine is bound at C-2 position in rosiglitazone, while an amine is bound at C-6 position in the present invention. Furthermore, the present invention has a substituted or unsubstituted aryl (phenyl) group, in which an oxygen, a nitrogen or a sulfur atom may exist at C-4 position of the pyrimidine or pyridine. Specifically, the substituent is incorporated at the para position of the pyrimidine or pyridine, which is the most stable position in terms of chemical structure, thereby a stable molecular structure being obtained. In addition to the above, according to the computer-aided molecular design(SAR), the active site of the PPARγ which is a molecule that influences insulin resistance, is three-dimensionally suitable for accepting the structure of the present invention compound, thereby the high pharmaceutical effect of the present invention compound being obtained. Accordingly, the present invention has a three dimensional structure distinguishable from a conventional rosiglitazone.

The present invention exhibits a strong blood sugar lowering activity and a strong blood lipid lowering activity, thereby capable of being used in the treatment or prevention of hyperglycemia. In particular, it has been found that the present invention is useful for the treatment of type II diabetes.

Further, it has been found that the present invention can be used in the treatment and/or prevention of other diseases such as hyperlipidemia, hypertension, cardiovascular disease and bulimia.

Experiments: Measurements of the Efficacies of Test Compounds

1) 2-Deoxy-D-[2,6-3H] glucose uptake assay (in differentiated 3T3-L1 cell)

Undifferentiated adipocyte 3T3-L1 cells were inoculated in a 24-well plate and cultivated in a CO

2

incubator at 37° C. To induce differentiation of the undifferentiated adipocytes, the cells were then incubated in a differentiation medium. After adding a certain concentration of each of the test compounds to the medium, the cells were again incubated for 24 hours. After removing the medium, the cells were washed with phosphate buffer, and 0.5 nM of insulin in phosphate buffer was added to the washed cells, followed by incubation for 40 minutes. Then, 0.5 uCi of 2-deoxy-D-[2,6-3H] glucose per well was again added to the cells, which were let stand for 4 minutes. Then, the cells were washed with phosphate buffer, and cell lysis buffer was added, so as to dissolve the cell membranes. The cell sample was placed into a liquid scintillation cocktail solution. The radioactivity of the sample was counted by a liquid scintillation counter. Based on the obtained results, the concentrations of the test compounds which resulted in 50% of maximum enhancement of insulin activation, were determined (EC

50

, nM). The results are presented in Table 1.

2) Triglyceride accumulation assay (in 3T3-L1 cells)

Undifferentiated adipocyte 3T3-L1 cells were inoculated in a 24-well plate and cultivated in a CO

2

incubator at 37° C. To induce differentiation of the undifferentiated adipocytes, the cells were then incubated in a differentiation medium for 48 hours. After adding a certain concentration of each of the test compounds to the differentiation medium, the cells were again incubated for 4 days. Then, the final cell sample was placed into 200 μl of 2-propanol. The amount of triglyceride in the cells were measured by Triglyceride Kit [YEONGDONG PHARMACEUTICAL CO. LTD., Korea] commercially available. Based on the obtained results, the concentration of the test compounds which resulted in 50% of maximum enhancement of rosiglitazone activation, were determined (EC

50

, nM). The results are presented in Table 1.

3) Cytotoxicity assay in primary cultured rat hepatocytes

Hepatocytes isolated from rat were inoculated in a collagen-coated 24 well plate and was incubated in a CO

2

incubator at 37° C. for 24 hours. Then, a certain concentration of each of the test compounds was added, and the cells were again incubated for 24 hours. The cells were then incubated in a 0.4% neutral red containing medium for 4 hours and washed once with phosphate buffer. 0.5 ml of a solution of 1% acetic acid-50% ethanol was added to the cells, which were let stand. 200 ul of the cell sample was taken and absorbance was measured at 570 nm. The cytotoxicity assay performed on hepatocytes was measured as 25% toxic concentration (TC

25

, uM). Then, the safety index, i.e. the TC

25

value in the cytotoxicity assay in hepatocyte/the EC

50

value in the triglyceride accumulation assay, was calculated. The results are presented in Table 1.

4) Blood glucose- and blood lipid-lowering action in mice with diabetes

Male mice with diabetes (KK/Ay: 10 weeks old, 5 animals/group) were housed and given free access to water and food. The animals received a daily oral administration of the test compounds for 5 days. After the last dose, a blood sample was drawn via the orbital sinus.

The plasma was analyzed for blood glucose content using the Glucose-E kit (YEONGDONG PHARMACEUTICAL CO. LTD., Korea), and for triglyceride content using the Triglyceride kit (YEONGDONG PHARMACEUTICAL CO. LTD., Korea). Based on the dose-response graph for blood glucose and triglyceride lowering activity, ED
