This invention relates to a novel hydroxyfattysulfonic acid analog having an elastase release-inhibiting activity, a pharmaceutically acceptable salt or a hydrate thereof.
The invention also relates to an elastase release-inhibiting composition which comprises as an active ingredient the hydroxyfattysulfonic acid analog.
Protease produced from neutrophils, one of lymphocytes, plays a main role in degrading foreign microorganisms such as bacteria or damaged cells and thus plays an important role in biophylactic reaetion. Neutrophilic elastase, one of serine proteases, (hereinafter simply referred to as elastase) is abundantly released from granules of neutrophils which may develop in the case of infections or inflammatory disorders. Elastase is an enzyme capable of decomposing proteins such as elastin, collagen, proteoglycan, fibronectin, etc., which constitute stroma of in vivo connecting tissues such as lung, cartilage, vascular wall, skin, ligament and so on. Further, it has been elucidated that this enzyme may also act on other proteins or cells.
The elastase maintains homeostasis of a living body, while its action is under control by endogenous inhibitor proteins, typically, α1-protease inhibitor, a 2-macroglobulin, secretory leukocyte protease inhibitor, etc. However, where a balance of elastase and endogenous inhibitor is lost by overproduction of elastase in inflammatory sites or by a lowered inhibitor level, the activity of elastase release may become uncontrollable to cause damage of tissues.
Elastase is known to be involved in pathology of certain diseases such as pulmonary emphysema, respiratory distress syndrome of adults, idiopathic pulmonary fibrosis, cystic pulmonary fibrosis, chronic interstitial pneumonia, chronic bronchitis, chronic sinopulmonary infection, diffuse panbronchiolitis, bronchiectasis, asthma, pancreatitis, nephritis, hepatic insufficiency, chronic rheumatism, arthrosclerosis, osteoarthritis, psoriasis, periodontitis, atherosclerosis, rejection against organ transplantation, premature amniorrhexis, hydroa, shock, sepsis, systemic lupus erythematosus, Crohn's disease, disseminated intravenous coagulation, cerebral infarction, cardiac disorders, ischemic reperfusion disorders observed in renal diseases, cicatrization of corneal tissues, spondylitis, and etc.
In view of the foregoing, an elastase release inhibitor is useful as a therapeutic or preventive agent for these diseases. Extensive studies have recently been made with expectation and various elastase release inhibitors have been reported. However, their activity is not quite satisfactory. Moreover, any clinically useful drug has not yet been found out as an elastase release-inhibiting agent comprising a hydroxyfattysulfonic acid analog.
It is an object of this invention to provide a novel compound having a prominent elastase release-inhibiting activity.
It is another object of this invention to provide an elastase release-inhibiting composition which comprises the hydroxyfattysulfonic acid analog or a pharmaceutically acceptable salt or hydrate thereof and a pharmaceutically acceptable carrier.

Test for Elastase Production by fMLP (N-formyl-Met-Leu-Phe)Stimulation
Rat neutrophils preparation was obtained 15-18 hours after intraperitoneal injection of a 1% sterile casein solution in saline (120 mL/kg). Cells were harvested by peritoneal lavage after the decapitation. The lavage fluid was ice-cold PBS (Phosphate-Buffered Saline). Peritoneal exudates were pooled, centrifuged and suspended in HBSS (Hanks' Balanced Salt Solution) at 1×107 cells/mL. Cytochalasin B (final concentration: 5 μg/mL) were added to prime the cells. The cells were added into a 96-well culture plate (190 μL/well) and then the compounds of the present invention at various concentrations (10−7 to 3×10−5 M) were added and incubated at 37° C. in an atmosphere of 5% CO2 in air. After 10 minutes, fMLP (20 μM, 10 μL) was added, while 10 μL of an HBSS solution containing 0.4% ethanol was added to the group to which no fMLP was added. After gently stirring, cells were incubated for further 10 minutes. The reaction was stopped on ice, and an incubated supernatant was recovered by centrifugation.
Assay of Elastase Activity in an Incubated Supernatant
Elastase activity in the incubated supernatant was measured using a specific elastase substrate, N-succinyl-L-alanyl-L-alanyl-L-proline-valine-MCA (Peptide Institue, Inc., Osaka), 0.12 mM in 50 mM Tris-HCl (pH 8.0). Fifty microliter of an incubated supernatant was added to the substrate solution (50 μL) and incubated at 37° C. for 30 minutes. Elastase activity was assayed at a wavelength of 360 nm at Excitation and 480 nm at Emission.
Elastase release-inhibiting activity (inhibition ratio) was calculated according to the following equation:
Inhibition ratio (%) {1−(A−C)/(B−C)}×100
wherein A stands for a fluorescence intensity when fMLP (1 μM) was added; B stands for a fluorescence intensity when fMLP (1 μM) and the present compound were added; and C stands for a fluorescence intensity when fMLP (1 μM) was not added.
Inhibitory concentration of 50% (IC50 Value) of the compound of the invention was calculated with a concentration-inhibition ratio curve. The results are shown in Table 1.
In the above Table, Compounds 23 and 33 correspond to the compounds of the Examples. The above results demonstrate that the compound of the present invention has a potent inhibiting activity in elastase production.
Effect on the Infarct Volume in Rat Transient MCA Occlusion (t-MCAo) Model.
Methods
Adult male Wistar rats (200-250 g) were anesthetized with 2% halothane in air. The right internal carotid artery (ICA) was carefully dissected. A silicon-coated suture (18 mm-long) was inserted into the ICA. Body temperature was maintained at 37° C. with a heating pad. After surgery, anesthesia was discontinued, and ischemic animal exhibited severe hemiparesis in the upper extremities. After 1 hour of MCA occlusion, the thread was removed to allow reperfusion of the ischemic area. Rats were received intravenously 1 hour-infusion of vehicle (10% of HP-β-CD) or compound 33 dissolved in vehicle immediately after reperfusion.
To measure infarct volume, rats were killed at 71 hours of reperfusion. Brains were perfused transcardially with physiological saline, and removed from skulls, cut into 2-mm coronal sections. The slices were immersed in 2% triphenyltetrazolium chloride (TTC) solution at 37° C. for 30 minutes. All values were presented as mean±SEM. For statistical analyses, Dunnett's multiple-range test was used.
Results
Compound 33 (0.1 mg/kg/min) dissolved in 10% of HP-β-CD was continuously administered for 1 hour from immediately after reperfusion. Compound 33 significantly reduced the total and cortex infarct volume as compared with vehicle-treated group at a dose of 0.1 mg/kg/min, 1 hour (
The hydroxyeicosenoic acid analog according to the invention has a potent elastase release-inhibiting activity and it is then useful as an elastase release inhibitor.
Elastase is known to be involved in pathology of certain diseases such as pulmonary emphysema, respiratory distress syndrome of adults, idiopathic pulmonary fibrosis, cystic pulmonary fibrosis, chronic interstitial pneumonia, chronic bronchitis, chronic sinopulmonary infection, diffuse panbronchiolitis, bronchiectasis, asthma, pancreatitis, nephritis, hepatic insufficiency, chronic rheumatism, arthrosclerosis, osteoarthritis, psoriasis, periodontitis, atherosclerosis, rejection against organ transplantation, premature amniorrhexis, hydroa, shock, sepsis, systemic lupus erythematosus, Crohn's disease, disseminated intravenous coagulation, cerebral infarction, cardiac disorders, ischemic reperfusion disorders observed in renal diseases, cicatrization of corneal tissues, spondylitis, and etc.
The elastase release inhibitor according to the invention is therefore useful as a therapeutic or preventive agent for the above-mentioned diseases.
