BACKGROUND ART

Diabetes causes various metabolic abnormalities including a chronic hyperglycemia state as a main characteristic, which shows various symptoms based on mouth dryness, polydipsia, polyuria, decrease in body weight and the like, based on hyperglycemia. It is known that, when such hyperglycemia state is maintained for a long time, various complications such as retinopathy, nephropathy, neuropathy, cardiac infarction and cerebral infarction based on arteriosclerosis, and the like are developed.

Diabetes is roughly divided into four types of type I diabetes (IDDM; Insulin Dependent Diabetes Mellitus), wherein pancreatic beta cells are damaged or destroyed to cause absolute insulin deficiency, type II diabetes (NIDDM; Non-Insulin Dependent Diabetes Mellitus) wherein relative insulin deficiency is developed due to insulin resistance and lower insulin secretion, specific diabetes which secondarily results from genetic abnormalities, other diseases and the like, and gestational diabetes. Some of those diagnosed with type II diabetes at the time of the onset may gradually lose their ability to secrete insulin with the progression of the disease and result in type I diabetes.

Considering the saccharometabolism of living organisms, energy sources and materials to be the constituent components of living organisms are taken into the body intermittently; for example, the brain keeps on consuming glucose. Under such situation, the blood glucose level is maintained almost constantly, and what enables such control of the blood glucose level includes hormones involved in control of the blood glucose level, metabolism in organs, interaction of exchanging sugar and the like between organs. Of such hormones, particularly the action of insulin involved in the control of the blood glucose level is important, and its disorder, namely, insulin resistance and lower secretion of insulin are considered to be deeply involved in diabetes.

Insulin is secreted from pancreatic beta cells, binds with an insulin receptor present on the membrane surface of the skeletal muscle cell and adipocyte, which are its target cells, after which tyrosine residue in the intracellular domain is self-phosphorylated. Then, tyrosine residues such as insulin receptor substrate (IRS), APS (adapter protein containing PH and SH2 domain) and the like are phosphorylated and PI.sub.3 kinase -Akt pathway is activated, which causes translocation of glucose transporter to cell membrane, where glucose uptake occurs to lower the blood glucose level. On the other hand, tyrosine phosphatase that causes tyrosine dephosphorylation to negatively control intracellular signal transduction by insulin is also present, and suppresses activation thereof. In this way, while tyrosine phosphorylation plays a key role in the insulin action, considering that tyrosine phosphorylation depends on the activity balance between tyrosine kinase (phosphorylation enzyme) and tyrosine phosphatase (dephosphorylation enzyme), tyrosine phosphatase is presumed to have function to significantly control insulin signal transduction directly together with tyrosine kinase.

At present, tyrosine phosphatase forms a large gene family and more than 70 some kinds of isozyme have been reported. Of such isozymes, protein tyrosine phosphatase 1B (PTP1B) is considered to be a phosphatase specific to insulin signal transduction. Particularly, given the reports on increased gene expression of PTP1B by high glucose culture, and shift of intracellular localization thereof, which decreases insulin receptor and IRS-1 tyrosine phosphorylation and induces insulin resistance (J. Biol. Chem., 270: 7724 7730, 1995; J. Biochem. (Tokyo), 123: 813 820, 1998); and introduction of wild-type PTP1B prevents translocation of glucose transporter GLUT4, resulting in ineffectiveness in a phosphatase activity deficient mutant, and recently on enhanced insulin sensitivity of PTP1B knockout mouse to be obesity resistant to high-fat diet (Science, 283: 1544 1548, 1999), this enzyme is suggested to be one possible target of insulin resistance improvement. In fact, an insulin resistance improvement effect of vanadic acid long known as a tyrosine phosphatase inhibitor has been acknowledged in animal test and the like.

Accordingly, such tyrosine phosphatase, particularly a drug that suppresses and/or inhibits abnormal activation of PTP1B can be a new type of therapeutic agent for diabetes, which enhances insulin sensitivity, insulin resistance and/or glucose resistance, and restores normal insulin intracellular signal transduction. In addition, application to a therapeutic drug for various diseases such as obesity, neurodegenerative disease and the like is also expected.

EXPERIMENTAL EXAMPLE

Experimental Example 1

Protein Tyrosine Phosphatase 1B Inhibitory Action

Preparation of Assay Buffer:

50 mM Tris-HCl buffer (pH 7.5), and 50 mM NaCl and 3 mM dithiothreitol (DTT) were prepared.

Preparation of Sample:

Respective 10 mM DMSO solutions of 0.1, 0.3, 1, 3 and 10 .mu.M test compounds were diluted with the above-mentioned assay buffer so that the final dimethyl sulfoxide (DMSO) concentration would be not more than 1%. As a control, an assay buffer was used.

Preparation of Substrate:

A synthetic peptide consisting of 12 amino acids corresponding to 1142nd 1153rd of insulin receptor sequence, wherein three tyrosines therein had been phosphorylated, was diluted with the above-mentioned assay buffer to 80 .mu.M.

Preparation of Enzyme:

A recombinant human protein tyrosine phosphatase 1B (manufactured by UBI) was diluted with the above-mentioned assay buffer (1.2 ng/25 .mu.l).

(Evaluation Method)

A sample (10 .mu.l) and a substrate (25 .mu.l) prepared as mentioned above were successively added to a 96 well plate, and an enzyme (25 .mu.l) prepared as mentioned above was added and mixed. After incubation at room temperature for 60 min., malachite green (120 .mu.l, Biomol), which is a phosphorus color fixing agent, was added, and the mixture was further incubated at room temperature for 20 min. to allow color development. The absorbance at 650 nm was measured on a plate reader, and the protein tyrosine phosphatase 1B inhibitory action of the test compound was evaluated. The results are shown in Table 68.

Experimental Example 2

Hypoglycemic Action

A 0.5% methyl cellulose suspension of the test compound was orally administered to male ob/ob mice (6 to 9 weeks old) grouped based on blood glucose level. A 0.5% methyl cellulose solution alone was administered to a control group.

The blood was drawn from the orbital vein with anesthesia at 3 hours after the administration. The blood was drawn under fasting by removing the feed immediately before test compound administration. The blood thus drawn was separated by centrifugation and the blood glucose level was measured from the obtained plasma according to the hexokinase method (glucose measure kit). For evaluation, decrease in the blood glucose level of the test compound administration group relative to the control group was shown in percentage. The results are shown in Table 68.

Blood Lipid Lowering Action

A 0.5% methyl cellulose suspension of the test compound was orally administered to 7-week-old db/db mice once a day for 14 days. The 0.5% methyl cellulose solution alone was administered to the control group.

The blood was drawn from the orbital vein with light ether anesthesia before test compound administration on day 7 day 14 under non-fasting condition. The blood thus drawn was separated by centrifugation and the plasma triglyceride concentration was measured from the obtained plasma according to the enzyme method (triglyceride measure kit). The results are shown in Table 69.
