Compositions for treating retinal degeneration and methods of production and use thereof
Compositions for use in methods of treating and/or inhibiting a pathologic ocular condition, as well as methods of producing and using same, are disclosed.
1. A method of enhancing cone photoreceptor survival in a subject having a pathologic ocular condition, the method comprising the step of:
administering to the subject a pharmaceutical composition comprising at least one antagonist of nuclear thyroid hormone receptor (TR), wherein the pharmaceutical composition is administered in an amount effective to inhibit and/or reduce nuclear thyroid hormone signaling in the retina of at least one eye of the subject, thereby enhancing cone photoreceptor survival in the subject, and wherein the at least one antagonist of nuclear thyroid hormone receptor is represented by Formula (I):
wherein:
R 1 is CF 3 , and R 2 and R 3 are H;
R 2 is CF 3 or NO 2 , and R 1 and R 3 are H; or
R 3 is CF 3 , NO 2 , N 3 , COCH 3 , F, or CH 2 N 3 , and R 1 and R 3 are H; and
wherein the pathologic ocular condition is at least one of age-related macular degeneration, Stargardt disease, retinitis pigmentosa, Usher syndrome, Leber's congenital amaurosis, achromatopsia, a rod-cone dystrophy, a cone-rod dystrophy, Bardet-Biedel syndrome, juvenile retinoschisis, choroideremia, and diabetic retinopathy.
2. The method of claim 1 , wherein the pharmaceutical composition is administered topically to or by injection into at least one eye of the subject.
3. The method of claim 1 , wherein the subject is a mammal.
4. The method of claim 1 , wherein the at least one antagonist is an antagonist of nuclear thyroid hormone receptor TRβ2.
5. The method of claim 1 , wherein the pharmaceutical composition further comprises at least one delivery agent that assists in delivery of the at least one antagonist to the at least one eye of the subject.
