Definitions
- the present invention relates to a therapeutic agent for age-related macular degeneration.
- Age-related macular degeneration occurs more frequently in people over 50 years of age, and is the leading cause of blindness in European and American people who are more vulnerable to light stimulation than the Japanese. The number is said to be more than 10 million. In addition, the number of cases has increased in Japan due to the westernization of lifestyles, the spread of TVs and personal computers, which have increased the chances of receiving light stimulation, and the prolonged life expectancy.
- This age-related macular degeneration shows symptoms such as abnormal aging of the retinal pigment epithelial cells, which degenerates the macula, causing the center of the visual field to be blurred, distorted, the center to be invisible, or dark.
- Age-related macular degeneration includes dry and exudative forms.
- the dry form is a form of the macula that has been damaged and atrophied, but does not require any special treatment because it has no subjective symptoms.
- the wet type is one in which the angiogenesis is caused by the stimulation of waste products and the retina is deformed, and treatment is necessary because retinal pigment epithelium detachment, neovascularization of the choroidal blood vessels, and subretinal hemorrhage lead to loss of vision.
- Therapies are surgical therapies such as laser photocoagulation, choroidal neovascular extraction, and macular migration, and provisional therapies such as low-line radiation therapy, photodynamic therapy, and transpupillary hyperthermia.
- drug treatments such as the use of hemostatic agents to prevent bleeding and the use of vitamins to nourish the retina are only symptomatic treatments and are effective. It is not a good therapy.
- An object of the present invention is to provide a medicament that directly acts on age-related macular degeneration.
- the present inventor has searched various drugs effective for the treatment of age-related macular degeneration, and recently found that a progesterone derivative represented by the following general formula (1) is excellent without affecting retinal function. It has been found that it has an inhibitory action on choroidal neovascularization, is excellent in reducing the age-related macular degeneration symptom, and has an excellent therapeutic effect, and has completed the present invention.
- the present invention provides a compound represented by general formula
- R 1 represents a hydrocarbon group having 1 to 23 carbon atoms.
- a therapeutic agent for age-related macular degeneration characterized by comprising a progesterone derivative represented by the following formula:
- the present invention also provides use of the progesterone derivative represented by the general formula (1) for producing a therapeutic agent for age-related macular degeneration. '
- the present invention provides a method for treating age-related macular degeneration, which comprises administering an effective amount of the progesterone derivative represented by the general formula (1).
- the therapeutic agent for age-related macular degeneration according to the present invention is excellent in the effect of suppressing choroidal neovascularization, and is associated with age-related macular degeneration such as a blurred or distorted central portion of the visual field due to degeneration of the macula of the retina. It has an excellent effect of alleviating and treating symptoms, and is particularly useful as a therapeutic agent for wet age-related macular degeneration.
- FIG. 1 shows the effect of FMPA administration on suppressing the expression of CNV in rats.
- FIG. 2 is a graph showing changes in the amplitude ratio ba of ERG a and b waves by FMPA administration.
- the progesterone derivative represented by the general formula (1) is described in the publication of W095 / 26974 and has an angiogenesis inhibitory effect, and is useful as a therapeutic agent for malignant tumors, diabetic retinopathy, rheumatism and the like. Although it is known, it is not known to have an effect of treating age-related macular degeneration.
- Examples of the hydrocarbon group R 1 in the general formula (1) include a linear, branched or cyclic alkyl or alkenyl group having 1 to 23 carbon atoms. Of these, an alkyl group having 1 to 17 carbon atoms is preferred. More preferably, R 1 is an alkyl group having 1 to 7 carbon atoms such as a methyl group, an ethyl group, an n_propyl group, an isopropyl group, an n-butyl group, an n-pentyl group, and an n-heptyl group, Particularly, acetic acid 9a-fluoromedroxyprogesterone in which R 1 is a methyl group (9 ⁇ -fluoromedroxyprogesuterone acetate: hereinafter may be referred to as FMPA) is preferable.
- FMPA acetic acid 9a-fluoromedroxyprogesterone in which R 1 is a methyl group (9 ⁇ -fluoromedroxyprogesuterone a
- the progesterone derivative represented by the general formula (1) is produced by a method described in W095Z26974 publication.
- the progesterone derivative represented by the general formula (1) strongly suppresses choroidal neovascularization, which is a cause of age-related macular degeneration, and suppresses degeneration of the macular region of the retina, as shown in Examples below. It is useful as a remedy for age-related macular degeneration, particularly exudative age-related macular degeneration.
- the therapeutic agent for age-related macular degeneration of the present invention is produced by a conventional method by mixing a commonly used pharmaceutical carrier in addition to the active ingredient, a progesterone derivative represented by the general formula (1).
- Pharmaceutical carriers include aqueous or non-aqueous solvents, solubilizers, stabilizers, preservatives, surfactants, soothing agents, buffers, suspending agents, thickeners and the like.
- the dosage form of the therapeutic agent for age-related macular degeneration of the present invention is preferably a liquid or an ointment.
- the therapeutic agent for age-related macular degeneration according to the present invention includes ophthalmic preparations such as eye drops, tenone injections, and fundus injections. Preferably, it is in a form acceptable as a therapeutic.
- epsilon aminocaproic acid dipotassium glycyrrhizinate, dichloromethane
- Anti-inflammatory drugs such as fenac sodium and pranoprofen
- vasoconstrictors such as tetrahydrozoline hydrochloride, feneryphrine hydrochloride, naphazolin hydrochloride, tetrahydrozoline hydrochloride
- anti-allergic drugs such as sodium cromoglycate and ketotifen fumarate
- chlorfe maleate Antihistamines such as biramine and diphenhydramine hydrochloride
- preservatives such as benzalkonium chloride, paraoxybenzoate, sorbic acid and chlorobutanol; polyoxyethylene hydrogenated castor oil and polyoxyethylene sorbitan monooleate Surfactant

- the pH of the preparation is appropriately adjusted with a pH adjuster such as hydrochloric acid, phosphoric acid, citric acid, sodium hydroxide, and sodium hydrogen carbonate.
- a pH adjuster such as hydrochloric acid, phosphoric acid, citric acid, sodium hydroxide, and sodium hydrogen carbonate.
- the dosage of the therapeutic agent for age-related macular degeneration according to the present invention is 0.01 to 30 mg of the compound of the general formula (1) in 1 to 5 divided doses according to the patient's symptoms, age, body weight, etc. It is preferable in view of the therapeutic effect of age-related macular degeneration.
- CNV model of choroidal neovascularization
- Rats (Brown Norway strain, 8 weeks old) were anesthetized under general anesthesia, and a single drop of a commercially available ophthalmic solution (Midulin P (registered trademark), Santen Pharmaceutical Co., Ltd.) was instilled.
- Photocoagulation was performed using a device (MC_7000L, manufactured by Nidek). The photocoagulation was focused on the deep layer of the retina, and was performed at eight locations in a diffuse manner avoiding thick retinal vessels (coagulation conditions: spot size 100 ⁇ m, output 100 mW, coagulation time 0.1 sec). Photocoagulation was performed on both eyes. After photocoagulation, fundus photography was performed to confirm the laser-irradiated site, and reared for 14 days to produce a rat CNV model.

The following operations were performed in a dark room under red light. Rats under general anesthesia Then, in the same manner as in Example 1, an ophthalmic solution was instilled to cause mydriasis. A single drop of 0.4% by weight of Benoxyl (registered trademark) (Santen Pharmaceutical Co., Ltd.) was applied to the anesthetized rat, which was then fixed on a measuring table, and a ground electrode (needle electrode) was placed on the tail of the rat. An indifferent electrode (needle electrode) was attached to the nose.
