Definitions
- the present invention relates to a hydroxyeicosagen acid conjugate, and more particularly, has an erasase inhibitory effect, is easy to purify, is easy to handle, is physically stable, and is useful as a pharmaceutical. Is a hydroxyeicosadic acid compound which is easy. Conventional technology
- elastase neutrophil elastase
- Elastase is an enzyme that mainly degrades proteins such as elastin, collagen, proteodarican, and fibronectin, which constitute the stroma of in vivo connective tissues such as lung, cartilage, vascular wall, skin, and ligament. It has also been shown to act on other proteins and cells.
- elastase In vivo, elastase is controlled by its endogenous inhibitor proteins, a1-proteazyme, ⁇ 2-macroglobulin, secretory leukocyte protease, and the like. Maintains homeostasis. However, if the balance between elastase and endogenous inhibitors is impaired by a decrease in inhibitory levels of elastase at the site of inflammation, control of elastase action is disrupted and tissue is damaged.
- elastase Diseases that have been suggested to be involved in the pathogenesis of elastase are: emphysema, adult respiratory distress syndrome, idiopathic pulmonary fibrosis, pulmonary fibrosis, chronic interstitial pneumonia, chronic bronchitis, chronic airway infection , Diffuse panbronchiolitis, bronchiectasis, asthma, rheumatism, nephritis, liver failure, chronic rheumatoid arthritis, arthrosclerosis, osteoarthritis, psoriasis, periodontitis, atherosclerosis, organ transplantation Rejection, premature rupture, bullous disease, shock, sepsis, systemic erythematosus, Crohn's disease, disseminated intravascular coagulation, cerebral infarction, heart disease, ischemia-reperfusion injury observed in renal disease, corneal scar Tissue formation and spondylitis are known.
- elastase inhibitors are useful as therapeutic or preventive agents for these diseases.
- research has been actively conducted in recent years, and various elastase inhibitors have been reported, but their effects are not necessarily satisfactory.
- No clinically useful drug has yet been found as an elastase inhibitor composed of a fatty acid derivative.
- this compound is a viscous oily substance and has a problem with stability over time, so that it is difficult to use it as a medicine. Disclosure of the invention

- the present inventors have conducted intensive studies on (5Z, 14Z) -1 (16R) -16-hydroxyeicosa-5,14-genic acid esters and salts for the purpose of solving the above problem.
- 5Z, 14Z)-(16R)-(16-hydroxyeicosa) -5,14-genic acid lysine salt represented by (I) is a specific, colorless powder, They have found that they have good physicochemical properties and are physiologically useful, and have completed the present invention.
- the present invention provides a compound of the formula (I)
- the hydroxyeicosadic acid compound of the present invention can be obtained by the method described in W099 / 59964, (5Z, 14Z)-(16R) —16-hydroxyeicosa-5,14-genic acid, It can be easily obtained by reacting (L) -lysine in an inert solvent such as methanol or ethanol.
- the compounds of the present invention can be administered systemically or topically orally or parenterally, such as intrarectally, subcutaneously, intramuscularly, intravenously, and transdermally.
- it can be orally administered in the form of tablets, powders, granules, powders, capsules, solutions, emulsions, suspensions, etc., which can be produced by a conventional method.
- preparations for intravenous administration aqueous or non-aqueous solutions, emulsions, suspensions, solid preparations which are dissolved in an injection solvent immediately before use and the like can be used.
- the compound of the present invention can also be formulated by forming an inclusion compound with a, j8 or arcyclodextrin or methylated cyclodextrin.
- the aqueous or non-aqueous solution, emulsion, suspension and the like can be administered by injection or the like.
- the dosage varies depending on age, body weight, etc., but is 0.0 mg / kg / day / adult for adults, administered once or several times a day.

- Example 1 the effects of the present invention will be described more specifically with reference to examples and test examples, but the present invention is not limited by these descriptions.
- Test Example 1 [Test of elastase production by stimulation with fMLP (N-formyl Met-Leu-Phe)] The compound (compound (1)) obtained in Example 1 and Example 18 in the specification of W099 / 59964 The compound (compound (1)) was used as the test drug, and rat neutrophils were dissolved in 1% case In solution was prepared 15 to 18 hours after intraperitoneal administration (120 ml / kg). After decapitation, cells were collected by peritoneal washing. Use cold PBS as the washing solution. Collect the peritoneal lavage fluid, centrifuge, and resuspend in HBSS at a cell concentration of 1 x cell Zml.
- cytochalasin B final concentration for the purpose of priming.
- f is the ML P a group without added plus 0.4% ethanol solution 10. after stirring, and incubated an additional 10 minutes. The reaction was stopped on ice, and the culture supernatant was collected by centrifugation.
- Elastase activity in the culture supernatant is an elastase-specific substrate
- the activity of inhibiting the release of Elasase was calculated by the following equation.
- Inhibition rate (%) ⁇ 1- (A-C) / (B-C) ⁇ X100
- A represents the fluorescence intensity when stimulated with ⁇ MLP (1 / iM).
- B represents the fluorescence intensity when fMLP (1 and the compound were added.
- C represents the fluorescence intensity when fMLP was not added.
- the 50% inhibitory concentration (IC50 value) was calculated from the concentration-inhibition curve.
- a stability test of the test drug was performed at 6, 2, and 3 months later.
- the residual ratio of the test drug was measured as follows. Precisely weigh about lmg of each test drug and heat
- UV absorption spectrophotometer (Detection wavelength: 200 nm)
- Table 3 shows the residual ratio of compound (I) and compound (II) when stored for 3 months under heating (40 ° C) and heating and humidification (40%, 75% RH).
- Compound (II) had a very low residual ratio, indicating poor stability.
- the compound (I) of the present invention was found to have a high residual ratio and to be stable.
- the compound according to the present invention has a sufficient elastase inhibitory effect, is easy to purify, and is physically stable. Therefore, according to the present invention, emphysema, adult respiratory distress syndrome, idiopathic pulmonary fibrosis, cystic pulmonary fibrosis, chronic interstitial pneumonia, chronic bronchitis, chronic airway infection, diffuse panbronchiolitis, bronchiectasis, Asthma, inflammation, nephritis, liver failure, rheumatoid arthritis, joints Sclerosis, osteoarthritis, psoriasis, periodontitis, atherosclerosis, rejection in organ transplantation, premature rupture of water, bullous disease, shock, sepsis, systemic lupus erythematosus, Crohn's disease, disseminated It has become possible to provide useful medicines for diseases such as intravascular coagulation, cerebral infarction, heart disease, renal disease, ischemia-reperfusion injury, formation of corneal scar
