Method for protecting a retinal neuronal cell
View Patent ↗A method of protecting a retinal neuronal cell by administering an effective amount of a prostaglandin F2α derivative to a patient. A method of preventing or treating an eye disease associated with retinal neuronal cell damage by administering a therapeutically effective amount of a prostaglandin F2α derivative to a patient.
1. A method for treating an eye disease selected from the group consisting of abnormal visual field, retinal vascular occlusion, diabetic retinopathy, ischemic optic neuropathy, macular degeneration, retinitis pigmentosa and Leber's disease, the method comprising administering to a patient in need thereof, wherein the patient does not have glaucoma, a therapeutically effective amount of a 15,15-difluoroprostaglandin F2α derivative is a compound represented by the following formula (1) or a salt thereof:
wherein R represents a hydroxyalkyl group, a formyl group, a carboxy group, an isopropoxycarbonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, an aminocarbonyl group, an alkylaminocarbonyl group or an arylaminocarbonyl group, and when R is an aryloxycarbonyl group or an arylaminocarbonyl group, the aryl moiety thereof may have a substituent.
2. The method according to claim 1 , wherein in the formula (1), R represents a carboxy group or a salt group thereof or an alkoxycarbonyl group.
3. The method according to claim 1 , wherein in the formula (I), R represents a carboxy group or a salt thereof or an isopropoxycarbonyl group.
4. The method according to claim 1 , wherein the compound is 16-phenoxy-15-deoxy-15,15-difluoro-17,18,19,20-tetranor-prostaglandin F2α.
5. The method according to claim 1 , wherein the disease is abnormal visual field.
6. The method according to claim 1 , wherein the disease is retinal vascular occlusion.
7. The method according to claim 1 , wherein the disease is diabetic retinopathy.
8. The method according to claim 1 , wherein the disease is ischemic optic neuropathy.
9. The method according to claim 1 , wherein the disease is macular degeneration.
10. The method according to claim 1 , wherein the disease is retinitis pigmentosa.
11. The method according to claim 1 , wherein the disease is Leber's disease.
