A NOVEL XANTHINE OXIDASE INHIBITOR AND A PHAR¬ MACEUTICAL COMPOSITION CONTAINING THE SAME
Technical Field
[1] The present invention relates to a novel xanthine oxidase inhibitor, a phar¬ maceutical composition for preventing or treating hyperuricemia comprising the same inhibitor as an active ingredient, and a pharmaceutical composition for preventing or treating gout, cardiovascular diseases, renal diseases and preecalampsia, caused by hy¬ peruricemia, comprising the same inhibitor as an active ingredient. Background Art
[2] Xanthine oxidase is an enzyme producing uric acid. A rapid increase of uric acid in the human body results in hyperuricemia, which causes gout. According to recent studies, hyperuricemia is related with various cardiovascular diseases and renal diseases (Alderman and Aiyer, 2004; CurrMedRes Opin, 20, 369-379, 2004). Also, hyperuricemia is related with preecalampsia (Lam C et al., Uric Acid and preecalampsia, Semin Nephrol.,2005 Jan; 25(l):56-60).
[3] Heretofore, allopurinol has been used in order to treat hyperuricemia and gout, car¬ diovascular diseases and renal diseases, resulting from hyperuricemia, by inhibiting the activity of xanthine oxidase. However, allopurinol causes severe side effects and is limited extremely in use. Disclosure of Invention Technical Solution
[4] Therefore, an object of the present invention is to provide a novel xanthine oxidase inhibitor, a pharmaceutical composition for preventing or treating hyperuricemia comprising the same inhibitor as an active ingredient, and a pharmaceutical composition for preventing or treating gout, cardiovascular diseases, renal diseases and preecalampsia, caused by hyperuricemia.

λλ
[13] According to the present invention, decursinol and a derivative thereof may be in the form of S(+)-isomer as well as R(-)-isomer.
[14] Decursinol, whose use as xanthine oxidase inhibitor has been identified for the first time according to the present invention, can be obtained by a chemical synthesis process, according to Cairns, N et al., D.P.J. Chem. Commun., 1264 (1986); W.Can., J.Chem., 49, 2297 (1971); and Jacobsen, E.N. et al., J. Am. Chem. Soc, 113, 7063 (1991); Han, H. et al., Tetrahedron Lett, 42, 4001 (2001); and Kim, S. et al., Tetrahedron Lett., 42, 7641 (2001). It can be also obtained by extraction from Angelica gigas, according to Phytochemistry, 30, 710-712 (1991), followed by isolation and pu-
rifϊcation.
[15] Decursinol may be used in the form of a pharmaceutically acceptable salt thereof.
Examples of pharmaceutically acceptable salts of decursinol include, but are not limited to, salts with inorganic bases such as sodium, potassium, magnesium, calcium, etc., and salts with organic bases such as lysine, ethanolamine, N, N'-dibenzylethylenediamine, angelic acid, etc.
[16] Decursinol and derivatives thereof have excellent effect for inhibiting xanthine oxidase. For example, such compounds significantly and efficiently reduce mice death caused by administration of xanthine oxidase into their cerebral ventricle, and remarkably inhibit the activity of xanthine oxidase as demonstrated by measurements of xanthine oxidase activity. Therefore, it is possible to efficiently prevent or treat hy¬ peruricemia, and gout, cardiovascular diseases, renal diseases and preecalampsia caused by hyperuricemia, by using the compounds. Cardiovascular diseased caused by hyperuricemia include hypertension and arteriosclerotic cardiovascular diseases. Renal diseases caused by hyperuricemia include uric acid nephropathy, gouty nephropathy, hypertensive (accompanied with hyperuricemia) nephropathy and renal failure.
[17] Since decursinol and derivatives thereof are contained in Angelica gigas, which has been used as a herb medicine, their safety is as good as proved.
[18] The pharmaceutical composition according to the present invention can be formulated in various types for parenteral or oral administration. Examples of repre¬ sentative formulations for parenteral administration include isotonic aqueous solutions or suspensions as injection formulations. Examples of representative formulations for oral administration include tablets or capsules. Such formulations may further include a diluent such as lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or glycine, or a lubricator such as silica, talc, stearic acid and a magnesium or calcium salt thereof, and/or polyethylene glycol, in addition to the effective ingredient. The tablets may further include a binder such as magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and/or polyvinylpyrrolidine. In some case, the tablets may include a disintegrating agent such as starch, agar, alginic acid or sodium salts thereof, or boiling mixture and/or an absorbent, a coloring agent, a flavoring agent, and a sweetening agent. The for¬ mulations are generally prepared by mixing, granulating or coating.
[19] The pharmaceutical composition according to the present invention is sterilized and/or may further include additives such as a preservative, a stabilizer, a hydrator or emulsion accelerator, an osmosis controlling salt and/or a buffering agent, and thera¬ peutically useful materials, and may be formulated by well known methods in the art.
[20] As an effective component of the inventive composition, decursinol or derivatives thereof can be administered by parenteral or oral routes once or more times daily in an
amount of 1 to 100 mg/kg(body weight) for mammals including humans.
[21] The present invention will now be described in more detail with reference to the following examples. However, the following examples are intended to illustrate the present invention in further detail and should by no means be construed as defining the scope of the invention. Mode for the Invention
[22] Examples
[23] Preparation Example: Purification of Decursinol
[24] 2€ of 80% methanol was added to lkg of chopped rhizome of Angelica gigas, followed by extracting at 40°C for 2 hours repeatedly twice. Resulting extracts were collected, subjected to a reduced-pressure reflux cooling tube to remove water from methanol, and then was dried completely with a reduced-pressure drier to obtain 29Og of extracts of Angelica gigas. Then, the extracts were subjected to high-pressure liquid chromatography (HPLC) to obtain decursinol. HPLC was performed under the following conditions:
[25] Column : Si60 (7D, 250mm X 4mm)
[26] Eluent : n-hexane:ethylacetate = 1:1
[27] Row rate : 1.0 ml/min.
[28] Detector : UV 340nm
[29]
[30] Example 1 : Test for effect of decursinol on mortality of the mice caused by admin- istration of xanthine oxidase into their cerebral ventricle
[31] In general, animals in which xanthine oxidase is administered into their cerebral ventricles have convulsions, resulting in a high mortality ratio. The following experiment was performed to determine the effect of decursinol, which is a novel xanthine oxidase inhibitor according to the present invention, on mortality caused by administration of xanthine oxidase.
[32] Decursinol(DC) obtained from the above Preparation Example was dissolved in
10% dimethyl sulfoxide (DMSO) solution. The resulting solution was orally ad¬ ministered to ICR mice (body weight 25~30g, MJ Ltd.) in a dose of 1, 10 and lOOmg decursinol/kg. After 1 hour of such pretreatment, 35D of xanthine oxidase (Sigma Chemical Co.) was administered into the cerebral ventricles of the mice, thereby causing convulsions. Then, a survival rate was checked every six minutes for 1 hour. Six mice were included per group. The control group was administrated with only 10% DMSO solution in the pretreatment. The results are shown in FIG. 1.
[33] As can be seen from FIG. 1, the mice of the control group shows the survival ratio of 0% after 12 minutes, while the group treated with decursinol shows the increased
survival ratio. Particularly, the mice of the treated group, to which 100 mg (decursinol)/kg was administered, shows the survival ratio of 67%.
[34] Example 2: Test for inhibition effect of decursinol on the activity of xanthine oxidase
[35] The following experiment was performed to determine the inhibition effect of decursinol on the activity of xanthine oxidase. To 0.05M phosphate buffer (pH 7.8) containing 50μM of xanthine and xanthine oxidase, decursinol obtained from the above Preparation Example was added in a concentration of O.lμM, lOμM and ImM, respectively. Then, the production rate of uric acid in each group was measured through variations in absorptivity at 295 nm (Rajagopalan KV, p 21-23, in CRC Handbook of Methods for Oxygen Radical Research, Greenwald RA (editor), 1985, CRC Press). As the control group, 0.5% DMSO solution was used instead of decursinol. Additionally, neither decursinol nor 0.5% DMSO solution was added to the blank group. The results are shown in FIG. 2.
[36] As shown in FIG. 2, the activity of xanthine oxidase was inhibited by all con¬ centration of decursinol including O.lμM of decursinol and the inhibition ratio increased in a concentration-dependent manner. Finally, the activity of xanthine oxidase was inhibited completely at the concentration of ImM of decursinol.
[37]
[38] Example 3: Renal protection effect by decursinol in rats suffering from hype¬ ruricemia
[39] Rat models suffering from hyperuricemia were prepared by providing twelve female rats (Sprague-Dawley rats: body weight 200~250g) with meal containing 2% of oxonic acid.
[40] Then, six rats of them were orally administered with decursinol (dissolved in 10%
DMSO) at 100 mg/kg/day (test group), while the remaining six rats were administered orally with 10% DMSO free from decursinol (control group). Concentration of uric acid in blood and concentration of protein in urine (albuminuria) were measured with the lapse of time (1, 2 and 4 weeks), and the average values were shown in FIGs. 3 and 4, respectively.
[41] As can be seen from FIG. 3, the rats administered with decursinol showed a significant drop in concentration of uric acid in blood, from 2 weeks after the treatment. Additionally, the rats administered with decursinol showed a significant drop in albuminuria compared to the control group (see FIG. 4). Accordingly, it can be believed that decursinol according to the present invention has excellent effect of treating hyperuricemia, and also has effects of treating gout, cardiovascular diseases, renal diseases and preecalampsia, caused by hyperuricemia.
