Description: DESCRIPTION QUINAZOLINE DERIVATIVES AND PHARMACEUTICAL APPLICATIONS THEROF TECHNICAL FIELD The present invention relates to a quinazoline derivative having a chymase inhibitory activity and a pharmaceutically acceptable salt thereof and to a pharmaceutical composition and a chymase inhibitor having the same as an effective ingredient. The present invention also relates to a method for producing the quinazoline derivative and a synthesis intermediate thereof. BACKGROUND ART Chymase is known to be present in secretory granules of mast cells (MC), which are closely related to inflammation, as one type of inflammatory cell. Further, human chymase similarly is mainly present broadly in MCs in the skin, heart, vascular walls, intestines, and other tissue ( Mast Cell Proteases in Immunology and Biology, Caughey, G. H., ed; Marcel Dekker, Inc.: New York, 1995). Human MCs are known to increase with bronchial asthma, allergic dermatitis and other allergic diseases, arteriosclerosis (Kaartinen et al., Circulation , 1994, 90., 1669), myocardial infarction (Kovanen et al., Circulation , 1995, 92., 1084), and other circulatory system diseases and rheumatoid arthritis (Gotis-Graham et al., Arthritis Rheum. , 1997, 40 . , 479). Further, it has been reported that the genetic polymorphism of chymase is correlated to the onset of eczema (Mao et al., Lancet, 1996, 348 , 581). Human chymase produces angiotensin II (Ang II) specifically from angiotensin I (Ang I) in the same way as an angiotensin converting enzyme. Ang II is closely related to regulation of the blood pressure, diuretic regulation, the migration and proliferation of smooth muscle cells etc. in the cardiovascular system tissue, the growth of the extracellular matrix, and other hypertrophy and remodeling of the cardiovascular system (Hideki Okunishi; Naibunpitsu-Tonyobyoka , 1996, 2(6), 535). Human chymase is reported to have the following actions due to its protease activity in addition to production of Ang II: 1) degradation of the extracellular matrix (Vartio et al., J. Biol . Chem. , 1981, 256, 471), activation of collagenase (Kovanen et al., J. Biol . Chem. , 1994, 269, 18134), and production of collagen (Kofford et al., J. Biol . Chem. , 1997, 271, 7127); 2) causing release of inflammatory cytokine, for example, release of TGF βl from extracellular matrix (Taipale et al., J. Biol . Chem. , 1995, 270, 4689) and production of IL-lβ (Mizutani et al., J. Exp. Med. , 1991, 174, 821); and 3) activation of stem cell factor (SCF) causing differentiation and proliferation of MCs (Longley et al., Pro. Nat . Acad. Sci . , 1997, 94 / 9017). Further, rat MC chymase is known to cause degranulation of MCs through IgE receptors, release chemical mediators such as histamine, partially hydrolyze the apolipoproteins of low density lipoproteins (LDL) to make modified LDL incorporated into macrophages, and convert the macrophages to foam cells (Mast Cell Proteases in Immunology and Biology, Caughey, G. H., Ed; Marcel Dekker, Inc.: New York, 1995). On the other hand, low molecular chymase inhibitors have already been shown in print ( Protease Inhibitors; Barrett et. al., eds . ; Elssevier Science B. V.: Amsterdam, 1986). Further, recently, as peptide inhibitors for human chymase, there have been α-keto acid derivatives ( O-A-93-25574 , Proc. Natl . Acad. Sci . USA, 1995, 92 . , 6738) and ,α-difluoro-β-keto acid derivatives (JP-A-9-124691 ) , while as peptide-mimetic inhibitors, there are trifluoromethylketone derivatives ( O-A-96-33974, JP-A-10-53579 ) , and ,α-difluoro-β-keto acid derivatives ( JP-A-10-7661 ) , while as nonpeptide inhibitors, there have been imidazolinedione derivatives ( J. Med. Chem. , 1997, 40, 2156), quinazoline derivatives (WO 97-11941), phenyl ester derivatives (JP-A-10-87567 ) , etc. There are no examples however of commercialization as medicaments. The above reports relating to chymase suggest that chymase plays an important role in the process of inflammation, repair, and cure of damaged tissue. That is, it breaks down the extracellular matrix at the inflammatory tissue, releases and activates inflammatory cytokine, causes cell migration and proliferation, reproduces the extracellular matrix, and makes the tissue repair. The excess reactions in this process are believed to be linked to various diseases. Therefore, by inhibiting chymase and suppressing the exacerbation of vascular permeability induced by chymase, utilization as a medicament for prevention and a medicament for treatment of allergic diseases such as bronchial asthma, cnidosis, atopic dermatitis, mastocytosis, scleriasis, rheumatic diseases such as arthritis, cardiac and circulatory system diseases arising due to abnormal exacerbation of Ang II production, for example, cardiac insufficiency, hypercardia, stasis cardiac diseases, hypertension, arteriosclerosis, peripheral circulatory disorders, revasoconstriction after PCTA, diabetic renal disorders or non-diabetic renal disorders, coronary diseases including myocardial infarction, angioendothelia, or vascular disorders accompanying arterialization or atheroma may be given as examples.

(J. Biol . Chem. , 1990, 265, 22348). The inhibitory activity of the quinazoline derivatives of the present invention with respect to chymase was measured in the following manner. That is, the purified enzyme solution was diluted to a suitable concentration with 0. IM tris-hydrochloride buffer (pH=7.5), IM sodium chloride, and 0.01% TritonX-100 to obtain an enzyme solution. A 10 mM dimethyl sulfoxide (hereinafter referred to as DMSO) solution of Suc-Ala- Ala-Pro-Phe-MCA (Peptide Institute) was diluted 20-fold at the time of use by 0. IM tris-hydrochlorate, IM sodium chloride, and 0.01% TritonX-100 to obtain the substrate solution. 75 μl of the enzyme solution warmed to 30 °C was mixed with 5 μl of DMSO solution of the test sample. The mixture was preincubated at 30°C for 10 minutes. Next, 20 μl of a substrate solution warmed to 30 °C was mixed with the test sample-enzyme mixture and incubated at 30 °c. After 10 minutes, 50 μl of 30% acetic acid was added to stop the enzymatic reaction. The amount of the AMC produced was quantified using a fluorescent photometer. At the same time, a blind test was carried out by adding, instead of the test sample solution, 5 μl of DMSO and performing the same reaction. The chymase inhibitory activity was expressed by a rate of inhibition, that is, the 50% inhibition concentration (IC 50 ), based on the blind test value. The quinazoline derivatives of the present invention all strongly inhibited human chymase at concentrations of 100 μM. The IC 50 values for typical compounds are shown in Table I. Table 1 Evaluation Example 2: Test of Human Chymase Induced Vascular Permeability Exacerbation Reaction Wister male rats (body weight 200 to 220 g, Charles River Japan) were used. In the backs of the rats from which the hair had been shaved off, 100 μl (20 mU: 1U being amount of enzyme for producing 1 nmol of AMC in 1 minute from Suc-Ala-Ala-Pro-Phe-MCA at pH7.5 and 30°C) of a solution of the human chymase enzyme solution purified in Evaluation Example 1 diluted 100-fold by PBS (phosphate buffered saline) was injected intracutaneously, then immediately thereafter a 0.5% (w/v) Evans Blue solution was administered from the tail artery. After 30 minutes, the rats were sacrificed by draining their blood under anesthesia with ether and the amount of dye leaking out to the back skin was measured. The region of the skin where the dye leaked out was cut off and 1.0 ml of IN KOH solution was added and the resultant mixture was allowed to stand at 37 °C overnight. Next, 4 ml of an acetone-0.6N phosphoric acid (13:5) mixture was added to extract the dye. The absorbance at 650 nm of the supernatant was measured. The calibration curve for measurement of the amount of the dye leaked out was prepared by injecting Evans Blue solution so as to give 10, 20, 30, 40, and 50 μg in the rat back skin and extracting the dye by the above method. Similarly, the amount of dye when administering intracutaneously 100 μl of the solution of the same composition but not containing human chymase was used as the control. Next, 10 mg/kg of the compound of Example 18 was orally administered. 30 minutes later, 100 μl (20 U) of human chymase the same as the non-drug administered group was injected intracutaneously and the amount of dye leaked out similarly measured. The rate of suppression of the amount of dye leakage due to the compound was calculated according to the following calculation formula. The rate of suppression for the compound of Example 18 was 64%. Rate of suppression of amount of leakage of dye (%) = [(amount of leakage of dye of compound administered group-amount of leakage of dye of control group) ÷( amount of leakage of dye of non-compound administered group- amount of leakage of dye of control group)] x 100 It is known that vascular permeability is exacerbated when inflammation is caused by an inflammation causing substance. Further, suppression of the exacerbation of vascular permeability has become one of the indicators for evaluation of anti-inflammation agents. In general, it is known that the histamine released by the degranulation of mast cells exacerbate the vascular permeability. The fact that a quinazoline derivative suppresses the exacerbation of vascular permeability due to the intracutaneous administration of chymase shows that the quinazoline derivative suppresses inflammation involving mast cells caused by the chymase. Evaluation Example 3: Test of Stability in Human Plasma Human plasma was diluted two-fold with 50 mM sodium phosphate buffer (ρH=7.2) for use as the test plasma solution. The test sample was made a DMSO solution of 1 mM concentration. 198 μl of the above two-fold diluted plasma solution warmed to 37 °C was added to 2 μl of the test sample DMSO solution and the resultant mixture was stirred and incubated at 37 °C. After 0, 5, and 15 minutes, 800 μl of acetonitrile was mixed with the test sample-plasma mixture to remove the protein, then a centrifugation operation (12,000 rpm, 1 minute) was carried out and the supernatant obtained. This was diluted two-fold with distilled water and measured for of the test sample by HPLC analysis. For the rate of recovery from the plasma, the rates of recovery at different times were calculated based on a calibration line of the test sample in a DMSO standard solution. The half-life (t 1/2 ) in plasma was calculated by exponential recurrence analysis from the rates of recovery of these different times. The half-lives (t 1/2 ) in plasma of representative compounds are shown in Table 1. Preparation Example 1: Production of Tablets 100.0 g of Compound 1 was mixed with microcrystalline cellulose in an amount of 22.5 g and magnesium stearate in an amount of 2.5 g and then tabletized by a single-action type tabletizing machine to produce tablets each containing 200 mg of Compound 1 and having a diameter of 9 mm and a weight of 250 mg. Preparation Example 2 : Production of Granules 30 g of Compound 1 was mixed well with lactose in an amount of 265 g and magnesium stearate in an amount of 5 g. The mixture was pressed molded, then pulverized and the granules sieved to obtain excellent 10% granules of 20 to 50 mesh. Preparation Example 3: Production of Suppository Vitepsol H-15 (made by Dynamite Nobel Co. ) was warmed to melt. To this was added Compound 1 to a concentration of 12.5 mg/ml. This was homogeneously mixed, then was added in 2 ml amounts to a rectal suppository mold and cooled to obtain rectal suppositories each containing 25 mg of the Compound 1. INDUSTRIAL APPLICABILITY The quinazoline derivative of the present invention inhibits chymase and further suppresses the exacerbation of vascular permeability induced by chymase, and therefore, is useful as a medicament for the prevention or treatment of allergic diseases or rheumatic diseases or cardiac and circulatory system diseases arising due to the abnormal exacerbation of angiotensin II production.
