The present invention relates to a guanidine compound which is useful as an active ingredient of a pharmaceutical composition, in particular, a pharmaceutical composition for preventing and/or treating vascular adhesion protein-1 (hereinafter abbreviated as VAP-1)-related diseases.
VAP-1 is an amine oxidase (semicarbazide-sensitive amine oxidase, SSAO) which is abundant in human plasma (Non-Patent Document 1), and shows remarkably increased expression in vascular endothelium and vascular smooth muscle of inflammatory regions. While the physiological role of VAP-1 has not been clarified until recently, VAP-1 gene was cloned in 1998, and VAP-1 has been reported to be a membrane protein that regulates rolling and migration of lymphocytes and NK cells as an adhesion molecule under regulation of expression by inflammatory cytokines. Although the amine acting as a substrate is unknown, it is considered to be methylamine generated in any part of a living body. It is also known that hydrogen peroxide and aldehydes produced due to the amine oxidase activity in the molecule are important factors of adhesion activity.
A recent report has demonstrated that the VAP-1 enzyme activity in plasma increases in patients with diabetes mellitus, whether type I or type II, and the increase is particularly remarkable in patients with diabetes mellitus suffering from retinopathy complications (Non-Patent Documents 2 and 3).
In addition, it has been reported that VAP-1 is related to the following diseases:
(1) cirrhosis, essential stabilized hypertension, diabetes mellitus, and arthrosis (Patent Documents 1 and 2);
(2) endothelium damage (in diabetes mellitus, arterosclerosis, and hypertension), cardiovascular diseases related to diabetes mellitus and uremia, pain related to gout and arthritis, and retinopathy (in diabetes mellitus patients) (Patent Document 3);

A human VAP-1 enzyme (SSAO) (reference: J Exp Med. 1998 Jul. 6; 188(1): 17 to 27) activity was measured by a radiochemistry-enzymatic assay using 14C-benzylamine as an artificial substrate. After homogenizing CHO (Chinese Hamster Ovary) cells stably expressing a human VAP-1 enzyme (SSAO) in a 50 mM phosphate buffer containing 1% NP-40, an enzyme suspension was obtained by taking the supernatant obtained by centrifugation. The enzyme suspension was preincubated with the compound of the present invention in a 96-well microplate at room temperature for 30 minutes. Subsequently, the enzyme suspension was incubated with 14C-benzylamine (a final concentration of 1×10−5 mol/L) to a final volume of 50 mL at 37° C. for 1 hour. The enzymatic reaction was stopped by the addition of 2 mol/L (50 μL) of citric acid. The oxidation products were extracted directly into a 200 μL toluene scintillator, and the radioactivity was measured with a scintillation spectrometer.

Eight-week to twelve-week Wistar male rats were fasted for 20 hours, and orally administered with a test drug (0.3 mg/1 kg). Heparin blood collection from the tail vein was performed immediately before the administration, and at 1 h, 3 h, 6 h, 12 h, or 24 h after the administration. The resulting blood was subjected to centrifugation at 14000 rpm for 5 minutes to separate plasma, and the VAP-1 enzyme activity in the resulting plasma was measured by a radio-enzyme assay method.
For the radio-enzyme assay method, 14C-benzylamine which is a synthetic substrate (10 μM) was reacted with the resulting plasma at 37° C., and the resulting metabolite was extracted with a mixture of toluene/ethyl acetate. The radioactivity was measured and taken as a VAP-1 enzyme activity in the plasma.

Seven- to eight-week SD rats (having weights up to 200 to 250 g during fasting) were used and fasted for 20 hours, and then intraperitoneally administered with 60 mg/ml/kg of streptozotocin (STZ) prepared with a 2 mmol/1 citric acid buffer (pH 4.5). At the same time, the control rats were injected with the same amount of a 2 mmol/1 citric acid buffer (pH 4.5). The blood glucose value was measured using a colorimetric method, and the rats that had showed a value of 350 mg/dl blood glucose levels on day 3 after the treatment with STZ were diagnosed with diabetes mellitus.
The test substance was given daily for 4 weeks after the treatment with STZ. After 4 weeks of the treatment with the test substance, 24-hour urine collection was performed using metabolic cages.
The amounts of urinary albunmin excretion after 4 weeks were 67 (mg/gCr) and 236 (mg/gCr) with the control group and the STZ-treated group, respectively, and the amount of urinary albunmin excretion of the STZ-treated group increased 3.5 times than that of the control group. On the other hand, as a result of the oral administration of the compound of Example 11 in the amount of 0.3 mg/kg once daily, an amount of urinary albunmin excretion was 103 (mg/gCr), which was decreased to 1.5 times than that of the control group.
Furthermore, in the test with the compound of Example 557, the amount of urinary albunmin excretion after 4 weeks were 45 (mg/gCr) and 234 (mg/gCr) with the control group and the STZ-treated group, respectively, and the amount of urinary albunmin excretion of the STZ-treated group was increased to 5.2 times than that of the control group. On the other hand, as a result of the oral administration of the compound of Example 557 in the amount of 0.3 mg/kg once daily, amount of urinary albunmin excretion was 105 (mg/gCr), which was decreased to 2.3 times than that of the control group.
Seven-week Long-Evans rats (having weights up to 200 to 250 g during fasting) were used and fasted for 20 hours, and then intraperitoneally administered with 60 mg/ml/kg of streptozotocin (STZ) prepared with a 2 mmol/1 citric acid buffer (pH 4.5). At the same time, the control rats were injected with the same amount of a 2 mmol/1 citric acid buffer (pH 4.5). The blood glucose value was measured using a colorimetric method, and the rats that had showed a value of 350 mg/dl blood glucose levels on day 3 after the treatment with STZ were diagnosed with diabetes mellitus.
The test substance was given daily for 2 weeks after the treatment with STZ. After 2 weeks of the treatment with the test substance, the retinal vascular permeability was examined after 24 hours from the date of the final administration. The retinal permeability was examined on the basis of the dye leakage into the retina after 2 h from the tail vein administration of 40 mg/ml/kg of Evans Blue Dye solution. The permeability as an index of the evaluation was expressed in the ratio of the retinal concentration/plasma concentration of the Evans Blue Dye. Measurement of the Evans Blue Dye concentration was carried out by measuring the absorbance using a plate reader.
After the result of the tests above, it was confirmed that some of the compounds of the formula (I) constantly exhibit a VAP-1 activity in blood in the oral administration test with rats. Therefore, the compounds can be used for treatment of VAP-1-related diseases or the like.
