Abstract

The present invention provides a treatment drug or prophylactic drug for diseases, disorders, or conditions related to endoplasmic reticulum (ER) stress. Specifically, the present invention provides a treatment drug or prophylactic drug for diseases, disorders, or conditions related to endoplasmic reticulum (ER) stress in the corneal epithelium, the drug containing a TGFβ-signal inhibitor. As a preferred TGFβ-signal inhibitor, the drug contains 4-[4-(1,3-benzodioxole-5-yl)-5-(2-pyridinyl)-1H-imidazole-2-yl]benzamide.

First claim

1 . A method of treating or preventing a disease, disorder or condition associated with endoplasmic reticulum (ER) stress in a corneal endothelium in a subject in need thereof, comprising the step of administering an effective amount of a TGF-β signal inhibitor to the subject.

2 . The method of claim 1 , wherein the disease, disorder or condition is associated with mitochondrial failure.

3 . The method of claim 1 , wherein the disease, disorder or condition is associated with apoptosis due to mitochondrial failure.

4 . The method of claim 1 , wherein the disease, disorder or condition is related to Fuchs' endothelial corneal dystrophy.

5 . The method of claim 1 , wherein the therapeutic or prophylactic drug suppresses the disease, disorder or condition comprising a disorder of a corneal endothelial cell in Fuchs' endothelial corneal dystrophy.

6 . The method of claim 1 , wherein the therapeutic or prophylactic drug suppresses at least one of the disease, disorder or condition selected from the group consisting of decreased corneal endothelial density, guttae formation, hypertrophy of the Descemet's membrane, hypertrophy of a cornea, corneal epithelial disorder, turbidity in corneal stroma, photophobia, blurred vision, visual impairment, ophthalmalgia, epiphora, hyperemia, pain, bullous keratopathy, eye discomfort, diminished contrast, glare, and edema of the corneal stroma.

7 . The method of claim 1 , wherein the TGF-β signal inhibitor comprises at least one of 4-[4-(1,3-benzodioxole-5-yl)-5-(2-pyridinyl)-1H-imidazole-2-yl]benzamide, BMP-7, an anti-TGF-β antibody, an anti-TGF-β receptor antibody, a siRNA of TGF-β, a siRNA of a TGF-β receptor, a shRNA of TGF-β, a shRNA of a TGF-β receptor, an aptamer of TGF-β, an aptamer of a TGF-β receptor, an antisense oligonucleotide of TGF-β, 6,7-dimethoxy-2-((2E)-3-(1-methyl-2-phenyl-1H-pyrrolo[2,3-b] pyridine-3-yl-prop-2-enoyl))-1,2,3,4-tetrahydroisoquinolone, 3-(6-methyl-2-pyridinyl)-N-phenyl-4-(4-quinolinyl)-1H-pyrazole-1-carbothioamide, 2-(3-(6-methylpyridine-2-yl)-1H-pyrazole-4-yl)-1,5-naphthyridine, 6-(4-(piperidine-1-yl) ethoxy)phenyl)-3-(pyridine-4-yl)pyrazolo[1,5-a]pyrimidine, 2-(5-chloro-2-fluorophenyl)-4-[(4-pyridinyl)amino]pteridine, 4-[3-(2-pyridinyl)-1H-pyrazole-4-yl]-quinoline, A-83-01 (3-(6-methyl-2-pyridinyl)-N-phenyl-4-(4-quinolinyl)-1H-pyrazole-1-carbothioamide), a pharmaceutical acceptable salt or solvate thereof, or a solvate of a pharmaceutically acceptable salt thereof.

8 . The method of claim 1 , wherein the TGF-β signal inhibitor comprises 4-[4-(1,3-benzodioxole-5-yl)-5-(2-pyridinyl)-1H-imidazole-2-yl]benzamide or a pharmaceutically acceptable salt thereof.

9 . The method of claim 1 , further comprising administering an effective amount of a therapeutic agent for mitochondrial failure induced by ER stress to the subject.

10 . The method of claim 9 , wherein the therapeutic agent for mitochondrial failure induced by ER stress is selected from the group consisting of BiP inducer X (BIX), 4-phenyl butyric acid (PBA), trimethylamine N-oxide (TMAO), tauroursodeoxycholic acid (TUDCA), and teprenone.

11 . The method of claim 1 , wherein the corneal endothelium is from a primate.

12 . The method of claim 1 , wherein the corneal endothelium is from a human.

13 . The method of claim 1 , wherein the TGF-β signal inhibitor is administered in combination with an additional pharmaceutical ingredient.

14 . The method of claim 1 , wherein the TGF-β signal inhibitor is administered as eye drops.
