Compositions and methods for treating misfolded protein ocular disorders
A method of treating an inherited ocular disorder associated with or caused by a misfolded ocular protein in a subject in need thereof includes administering to the subject a compound that promotes clearance of misfolded ocular protein.
1 . A method of promoting clearance of misfolded ocular proteins in a subject in need thereof, the method comprising: administering to the subject a therapeutically effective amount of a compound selected from:
a pharmaceutically acceptable salt, tautomer, or solvate thereof, or combinations thereof, wherein the subject has a non syndromic autosomal dominant retinitis pigmentosa associated with or caused by the misfolded ocular protein.
2 . The method of claim 1 , wherein the compound is selected from:
a pharmaceutically acceptable salt, tautomer, or solvate thereof, or combinations thereof.
3 . The method of claim 1 , wherein the compound is administered to the subject at early stage or mid stage of the non syndromic autosomal dominant retinitis pigmentosa.
4 . The method claim 1 , wherein the misfolded ocular protein is a misfolded opsin.
5 . The method of claim 1 , wherein the misfolded ocular protein is a misfolded opsin protein that comprises a mutation in its amino acid sequence.
6 . The method of claim 5 , wherein the mutation is at least one of P23H, C110Y, D190N, T17M, P347S, or P267L.
7 . The method of claim 1 , wherein the therapeutically effective amount is an amount effective to accelerate the degradation of the misfolded ocular protein, improve ocular protein homeostasis, improve or preserve visual function, inhibit photoreceptor cell death, and/or improve or preserve retinal structure.
8 . The method of claim 7 , wherein the improvement or preservation in visual function include an improvement or preservation of photopic electroretinogram (ERG) response.
9 . The method of claim 7 , the wherein the improvement or preservation in retinal structure is an improvement or preservation of outer nuclear layer (ONL) thickness.
10 . The method of claim 1 , wherein the compound is administered by at least one of topical administration, systemic administration, intravitreal injection, and intraocular delivery.
11 . A method of treating an inherited ocular disorder associated with or caused by a misfolded ocular protein in a subject in need thereof, the method comprising: administering to the subject a therapeutically effective amount of a compound selected from:
a pharmaceutically acceptable salt, tautomer, or solvate thereof, or combinations thereof, wherein the subject has a non syndromic autosomal dominant retinitis pigmentosa associated with or caused by the misfolded ocular protein.
12 . The method of claim 11 , wherein the compound is selected from:
a pharmaceutically acceptable salt, tautomer, or solvate thereof, or combinations thereof.
13 . The method of claim 11 , wherein the compound is administered to the subject at early stage or mid stage of the non syndromic autosomal dominant retinitis pigmentosa.
14 . The method of claim 11 , wherein the misfolded ocular protein is a misfolded opsin.
15 . The method of claim 11 , wherein the misfolded ocular protein is a misfolded opsin protein that comprises a mutation in its amino acid sequence.
16 . The method of claim 15 , wherein the mutation is at least one of P23H, C110Y, D190N, T17M, P347S, or P267L.
17 . The method of claim 11 , wherein the therapeutically effective amount is an amount effective to accelerate the degradation of the misfolded ocular protein, improve ocular protein homeostasis, improve or preserve visual function, inhibit photoreceptor cell death, and/or improve or preserve retinal structure.
18 . The method of claim 17 , wherein the improvement or preservation in visual function include an improvement or preservation of photopic electroretinogram (ERG) response.
19 . The method of claim 17 , the wherein the improvement or preservation in retinal structure is an improvement or preservation of outer nuclear layer (ONL) thickness.
20 . The method of claim 11 , wherein the compound is administered by at least one of topical administration systemic administration, intravitreal injection, and intraocular delivery.
