Description

FIELD OF THE INVENTION

[0001] The present invention relates to inhibitor compositions of phospholipase A(2) (hereinafter referred to as PLA (2)) activity characterized by comprising as the active ingredient either an oxa(thia)zolidine derivative or a pharmaceutically acceptable composite thereof, a use of said inhibitor compositions in mammalian which require to relieve sick conditions accompanied by the enhanced PLA(2) activity, and novel oxa(thia)zolidine derivatives which are useful as an active ingredient for said inhibitor compositions.

BACKGROUND OF THE INVENTION

[0002] Inflammation is a series of defensive response process caused in the tissues, induced by the applied injurious events (inflammatory stimuli) on any parts of a human body. When the tissues are damaged by inflammatory stimuli that could be caused by bacterial infections, immunological responses or physical injuries, the tissues respond (acute inflammation) to the stimuli, followed by excluding the stimuli to repair the damages. Alternatively, if the exclusion is difficult, the damages are progressed to induce continuously tissue swelling (chronic inflammation). Inflammation is well known to be associated with several diseases, and various mediators are known to be associated with each step during the inflammation process, constituted with activation and interactions of various cells.

[0003] PLA(2) is a diverse class of enzymes, catalyzing preferentially the hydrolysis of the sn-2 acyl-ester of glycerophospholipids, that are major components of cell membranes, to liberate fatty acids. It is also well known that the PLA(2)s are responsible for deacylation-reacylation process required for cell membrane repair and maintenance, and the hydrolyzed products, as well as the further metabolites, are lipid mediators with strong diverse physiological activities. The liberated product, arachidonic acid with some activity as mediator, is further metabolized in respective inflammation-associated cells to prostagladins, thromboxanes, lipoxins, leukotrienes, etc., which induce characteristic physiological responses, respectively (Irvine, R., Biochemical Journal 204: 3-16 (1982).). The other product, lysophosphatidylcholine not only plays roles as mediator, but also is utilized as a precursor of platelet activating factor (hereinafter referred to as PAF). These lipid mediators play an essential role to maintain homeostasis of living organisms, however, when they produced to excessive amounts under sick conditions associated with inflammation, they could cause adversely effects. In fact, steroidal anti-inflammatory drugs and various non-steroidal anti-inflammatory drugs (hereinafter referred to as NSAID) are known to interfere with the arachidonic acid cascade, have been widely used in clinical therapy. As PLA(2) is positioned at the upstream of the arachidonic acid cascade and is believed to be the rate-limiting step in the generation of these lipid mediators, this enzyme has been expected to be the promising target for research and development of novel anti-inflammatory drugs (Glaser, K. B., Advances in Pharmacology 32: 31-66 (1995).).

[0004] Recently, numerous PLA(2)s have been identified and rapidly become a large superfamily consisted of more than 15 isozymes are subdivided into four groups, on the basis of the protein structures and the characteristics in the enzymatic activities (Dennis, E. A., Trends in Biochemical Science, 22: 1-2 (1997), and Balsinde, J. et al, Annual Review of Pharmacology and Toxicology, 39: 175-189 (1999), etc.). Among them, it is noted that only the particular isozymes are shown high specificity against arachidonyl-phospholipids, as well as the enzymatic activity of the particular isozymes are selectively enhanced in a case of inflammatory disorder. As the examples for such inflammation-associated PLA(2)s, type IV-cytosolic PLA(2) (hereinafter referred to as IV-cPLA(2); molecular weight 85 kDa) and the subtypes IIA, IID, V and X of secretory PLA(2) (hereinafter referred to as sPLA(2); molecular weight 14 kDa) may be exemplified. Among these, IV-cPLA(2) is particularly considered as the responsible isozyme for producing the lipid mediators in the inflammatory diseases, which is supported by findings from the `knockout`(IV-cPLA(2).s- up.-/-)mice (Uozumi, N. et al, Nature 390: 619-622 (1997), and Bonventre, J. V. et al, Nature 390: 622-625 (1997).). Therefore, the enhanced lipid mediators production under sick conditions could be suppressed by inhibiting IV-cPLA(2) activity, thereby facilitating remedy and/or prevention of the inflammatory diseases. Such diseases can be exemplified as following: anaphylaxis induced by various inflammatory stimuli, septic shock, fever and pain; respiratory diseases, such as bronchitis, pneumonia, and adult respiratory distress syndrome; digestive diseases, such as inflammatory intestine disorder, Crohn's disease, ulcerative colitis, hepatitis, and nephritis; cardio-vascular diseases, such as vasculitis and arteriosclerosis; allergic inflammatory diseases, such as rhinitis, asthma and atopic syndromes; and auto-immune diseases such as rheumatism; ischemia/reperfusion injuries, such as cerebral infarction and myocardial infarction; nerve degenerative diseases, solar keratosis, psoriasis, and the like.

[0005] However, as no drug has been developed yet, which shows remedial effects in the clinical therapies by inhibiting the enzyme activity, it is desired to develop such a new drug that can specifically and comprehensively control the lipid mediators production in inflammatory diseases, with excellent therapeutic and preventive effects.

[0006] In WO97/05135, compounds represented by the following general formula; 4

[0007] are disclosed as oxa(thia)zolidine derivatives having activity of inhibiting the PLA (2) activity. However, the compounds which show to have said inhibitory activity are limited to ones wherein the second and the fourth positions are substituted by either oxo or thio. Furthermore, in WO93/10789, 2-imino-4-oxothiazolidine derivative represented by the following chemical formula is disclosed. 5

However, it is not known so far that those oxa(thia)zolidine derivatives have PLA(2) inhibitory activity or anti-inflammatory activity.

PHARMACOLOGICAL TEST EXAMPLE 1

[0117] PLA(2) Activity

[0118] The PLA(2) activity was measured by quantitatively analyzing the fluorescent product of hydrolysis from 1,2-bis-(4,4-difluoro-5,7-dimethyl- -4-bora-3a,4a-diaza-s-indecene-3-undecanoyl)-sn-glycero-3-phosphocholine (hereinafter referred to bis-BODIPY.RTM.FL C.sub.11-PC, Molecular Probes, Inc., B-7701) using activated U937 cells (human monoblastic lymphoma cell line) by inflammatory stimulus (Meshulam, T. et al., The journal of Biological Chemistry 267 (30): 21465-21470 (1992); and Solito, E. et al., British Journal of Pharmacology 124: 1675-1683 (1998).). The substrate bis-BODIPY.RTM.FL C.sub.11-PC is incorporated into cellular membranes, the proximity of the BODIPY FL fluorophores on adjacent phospholipid acyl chains causes fluorescence self-quenching. Separation of the fluorophores upon hydrolytic cleavage of one of the acyl chains by PLA(1) or the PLA(2) results in increased fluorescence. In the activated U937 by inflammatory stimulus, it is shown that this substrate should be cleaved enzymatically by IV-cPLA(2) from the feature of its behaviors including sensitivity profiles against the inhibitors.

[0119] The human cell line U937 was purchased from Dai-Nippon Pharmaceuticals Co., Ltd. The cells were maintained by transferring every 3-4 days into RPMI 1640 medium (Sigma Chemical Co., R6504) supplemented with heat-inactivated 10% fetal bovine serum (Fetal Bovine Serum, Sigma Chemical Co., F 4135) in a 5% CO.sub.2 humidified atmosphere at 37.degree. C. The cells were transferred into the culture medium described above, containing 1.2% (v/v) dimethylsulfoxide (hereinafter referred to as DMDO, Nacalai tesque Co., Ltd., D 134-45), and pre-cultured for 96 to 120 hours so as to differentiate into the macrophage-like cells to be provided for the assay. The macrophage-like cells were collected and washed by centrifugation with the Assay medium (Dulbecco's phosphate buffered saline (hereinafter referred to as PBS)-2.2 mM glucose-2.5 .mu.m albumin). Then, Phorbol 12-Myristate 13-Acetate (hereinafter referred to as TPA, Sigma Chemical Co., P 8139) was added to the Assay medium to be 1.times.10.sup.-8M as the final concentration. Then, the macrophage-like cells were further cultured for an hour to be activated (Rzigalinski, B. A. & Rosenthal, M. D., Biochimica et Biophysica Acta 1223: 219-225 (1994); and Gonchar, M. V. et al., Biochemical and Biophysical Research Communication, 249: 829-832 (1998).).

[0120] For preparing substrate liposome suspension, bis-BODIPY.RTM.FL C.sub.11-PC was combined with phosphatidylcholine (Sigma Chemical Co., P 7769) at 1:9 molar ratio in chloroform, and dried under nitrogen flow. The dried mixture was suspended with the Assay medium at 100 .mu.g/mL, voltexed and sonicated for an hour on ice under dark condition.

[0121] The test compound was dissolved with DMSO at 30 mM, and the solution diluted with either DMSO or the Assay medium before addition into the reaction mixture. The DMSO concentration in the reaction mixture was controlled so as to be no more than 0.1%. The 30-fold concentration of test compound solution was put into each well of MICRPTEST.TM. Tissue Culture Plate, 96 Well (Falcon, 3072) at a rate of 2.5 .mu.L/well. To the respective well was added 25 .mu.L/well of the activated U937 cell suspension (6.times.10.sup.6 cells/mL), and the cells were pre-cultured for 120 min. at 37.degree. C. in a 5% CO.sub.2 atmosphere incubator. 47.5 .mu.L/well of the substrate liposome suspension with 1.5.times.10.sup.-6M A23187 (Sigma Chemical Co., C 7522) was added into each well to prepare 75 .mu.L/well of the total reaction mixture, followed by culture for 30 min. under the same conditions with shielding against light. 100 .mu.L/well of 0.1% GEDTA (Dojindo Laboratories Co. Ltd., 348-01311) methanol solution was added into each well and mixed to stop the reaction. The increased fluorescence of the hydrolysis product by the enzyme was determined by measuring the fluorescence emission intensity at 535 nm with excitation at 485 nm from the top side of each plate at 37.degree. C., using a Multi Functional Microplate Reader SPECTRA FLUOR PLUS (TECAN Austria GmbH). The measurements for the same test lot were carried out under the same sensitivity as the optimum gain condition for the first microplate measurement. In the test, each treatment was repeated three times, the reaction mixture plot without cells was used as the blank, and arachidonyl trifluoromethyl ketone (hereinafter referred to as AACOCF.sub.3, Calbiochem-Novabiochem Corp., 100109) was used for the positive control treatment. PLA(2) activity in each test plot was determined by subtracting the mean value of the fluorescence emission intensity in the blank plot from that of each well, respectively. There was statistically no significant difference between the plots with and without 0.1% DMSO. In the pre-examination, the fluorescence emission intensity based on the substrate hydrolysis was increased linearly with time progression until 90 min. Besides, hydrolysis as the basic metabolic activity, which was measured as the enzymatic activity in the subcultured cells neither being differentiated nor activated, without A23187 treatment condition, was shown about one seventh of that exerted by the activated cells. Thus, the difference obtained by subtracting the basic metabolic activity from each enzymatic activity was determined as the inflammatory activated PLA(2) activity, and the inhibition rate was calculated by the inflammatory activated PLA(2) activity per the mean value of that of the control plots with and without DMSO, for evaluating the activity of the respective test compounds. The inhibitory activity measured for the respective compounds of the present invention are shown in Table 3 below, for example.

PHARMACOLOGICAL TEST EXAMPLE 2

[0122] Mouse Ear Edema Induced by TPA

[0123] This test was carried out referring to the method of Carlson, R. P. et al. (Agents and Actions, 17(2): 197-204 (1985).) and the method of Chang, J. (European Journal of Pharmacology, 142: 197-205 (1987).). More specifically, 5 .mu.g/20 .mu.L of TPA (Sigma Chemical Co.), dissolved with ethanol, was topically applied to the anterior and posterior surfaces of the right ear of an ICR-strain male mouse (6-7 weeks old). 6 hours later, the thickness of each ear at the particular part was respectively measured three times using a digimatic micrometer to calculate the mean value. Ear edema was determined by subtracting the mean thickness of the left ear as without treatment from that of the right ear as TPA-applied. Topical application activity was evaluated by applying an acetone solution of the compound of the present invention or 0.1% Tween 80/acetone solution thereof similarly to the anterior and posterior surfaces of the right ear 30 min. before and 15 min. after the TPA-application. As the positive control, an acetone solution of Dexamathasone-21-acetate (hereinafter referred to as DEX-Ac, Sigma Chemical Co., D 1881) and an acetone solution of indomethacin were applied similarly as for the compound of the present invention. Oral administration activity was evaluated by administrating 0.2% Tween 80 suspension of the compound of the present invention forcibly and perorally to the mouse an hour prior to the TPA-application. As the positive control, 100 mg/kg of Hydrocortisone (Sigma Chemical Co., H 4001) suspension was applied to the mouse similarly as for the compound of the present invention. By the treatment with the compounds of the present invention, anti-inflammatory activities, for example as shown in Table 4, were measured for the respective compounds. Furthermore, it was noted that the mice of both DEX-Ac administration group and indomethacin administration group showed generally bad symptoms and reducing their body weight after 24 hours. On the contrary, the mice in the each group applied with the compounds of the present invention showed good condition and no significant change in their body weight.

PHARMACOLOGICAL TEST EXAMPLE 3

[0124] Mouse Delayed Contact Dermatitis Induced by Picryl Chloride

[0125] This pharmacological test was carried out referring to the method of Asherson, G. L. & Ptak, W. (Immunology, 15: 405-416 (1968).) and the method of Jun Hiroi (Folia Pharmacology of Japan, 86: 233-239 (1985).). More specifically, hairs on the abdomen of an ICR-strain male mouse were removed using an electric clip and an electric shaver. Then, 0.1 mL of 7% ether solution of picryl chloride (Tokyo Kasei Kogyo Co., Ltd., C 0307) was applied onto the abdomen for sensitization. On the sixth day after the sensitization, 20 .mu.L/ear of 1% olive oil solution of picryl chloride was topically applied to the anterior and posterior surfaces of both ears of the mouse to induce contact dermatitis (first induction). Before and 24 hours after the induction, the thicknesses of the particular parts on the both ears were measured three times, respectively, using a digimatic micrometer (Mitsutoyo Co., Ltd.) to work out the average values. Ear edema of the both ears was respectively determined by subtracting the average thickness of the each ear before the induction from that on 24 hours after the induction, so that a grouping was carried out to separate the appropriate individuals. On the fourth day after the first induction, the hairs on the abdomen were removed again, and 0.1 mL of 7% ethanol solution of picryl chloride was applied thereto for additional sensitization. The contact dermatitis for evaluating activity was induced by re-applying 20 .mu.L/ear of 1% olive oil solution of picryl chloride to the anterior and posterior surfaces of both ears (second induction) on the seventh day after the additional sensitization (on the 18th day after the first sensitization). The activity of each compound of the present invention was evaluated as the inhibition on the contact dermatitis as compared with that of the vehicle applied control. That is, the thicknesses of the particular portions of the both ears were measured respectively three times with a digimatic micrometer to work out the mean values before, 24 hours and 48 hours after the second induction. Ear swelling was determined by subtracting the ear thickness before the second induction from that on 24 hours and 48 hours after the second induction, respectively. Topical application activity was evaluated by applying 25 .mu.L of the acetone solution of the compound of the present invention similarly to the anterior and posterior surfaces of the right ear one hour before and 16 hours after the second induction. As the positive control, 0.02 mg/20 .mu.L of acetone solution of Dexamethasone (hereinafter referred to as DEX, Wako Pure Chemical Industries Ltd., 047-18863) was applied similarly as for the compound of the present invention. With respect to the inhibitory activity in topical application tests, the topical activity was determined by the inhibition of the applied right ear edema, and the translocation and distribution property was determined by the activity onto the swelling of non-treated left ear. Oral administration activity was evaluated by administrating 0.5% methyl cellulose suspension of the compound of the present invention forcibly and perorally to the mouse an hour before and 16 hours after the second induction. As the positive control, 20 mg/kg of Prednisolone (Sigma Chemical Co., P 6004) suspension was administrated similarly as for the compounds of the present invention. With respect to the compounds of the present invention, the anti-allergic activities as shown in Table 4 were measured. Furthermore, it was noted that the mice of DEX administrated group showed generally bad symptoms and reducing their body weight significantly 48 hours after the second induction. On the contrary, the mice in the each group applied with the compounds of the present invention showed good condition and no significant change in their body weight. As the examples, the body weight changes in the mice for 48 hours after the second induction when they were administrated with the compounds shown in Table 5 are shown in Table 6.

PHARMACOLOGICAL TEST EXAMPLE 4

[0127] Acetic Acid Writhing

[0128] This test was carried out referring to the method of Inoue, K., Motonaga, A. & Nishimura, T (Arzneimittel Forshung/Drug Research, 41 (1): 235-239 (1991)). More specifically, 7.5 mL/kg of 0.9% acetic acid solution was injected intraperitoneally into an ICR-strain male mouse (5 to 7 weeks old), and the induced writhes (characteristic behaviors of convulsive contracting the abdomen, twisting the body and/or extending the legs) were observed. Number of writhes of each mouse was measured during 10 to 20 min. period after acetic acid administration. The compound of the present invention was homogeneously suspended in 2% Tween 80/saline for injection use, and was injected intraperitoneally 30 min. before the induction by the acetic acid injection. Alternatively, the compound of the present invention was homogeneously suspended in 2% Tween 80/distilled water, and was administrated orally two hours before the induction by the acetic acid injection. The analgesic activity of the compounds according to the present invention was evaluated on the basis of the degree of inhibiting the number writhes by the administration of the compounds. As the positive control, indomethacin or aspirin was administrated. The analgesic activity of the compounds according to the present invention measured in this test were exemplified in Table 7.

[0129] In addition, no remarkable intoxicated symptom was observed on any mouse in the groups, which was injected intravenously in the tails even 100 mg/kg of the compounds according to the present invention.

[0130] As it is understood from the results of the foregoing pharmacological tests, it is apparent that the compounds according to the present invention have excellent inhibitory activities on the PLA(2) activity, being less toxic, having strong anti-inflammatory activities and/or anti-allergic activities. Thus, the composites containing the compounds according to the present invention are useful as therapeutic and/or protective drugs of new type, since sick conditions accompanied the activated PLA(2) activity are cured to show excellent effects against such associated diseases, by the administration of the composites.
