Arginyl-glutamine dipeptide for treatment of pathological vascular proliferation
View Patent ↗The subject invention provides dipeptides useful in preventing pathological proliferation of blood vessels. The dipeptides of the subject invention are particularly advantageous because they are stable, bioavailable, and can be formulated in an aqueous solution.
1. A method for treating a condition selected from the group consisting of retinopathy of prematurity, diabetic retinopathy, vascular proliferative retinopathy and pathological vascular proliferation wherein the method comprises administering, to a patient who has at least one of these conditions, and is thus in need of such treatment, an amount of the dipeptide arginyl-glutamine, or a salt thereof, that is sufficient to treat the condition.
2. The method, according to claim 1 , wherein the vascular proliferation is associated with tumor growth.
3. The method, according to claim 1 , wherein the vascular proliferation being inhibited is in a mammal.
4. The method, according to claim 3 , which comprises local administration of the dipeptide, or a salt thereof.
5. The method, according to claim 3 , which comprises systemic administration of the dipeptide, or a salt thereof.
6. The method, according to claim 5 , wherein the administration is enteral.
7. The method, according to claim 3 , which comprises oral consumption by the mammal of the dipeptide, or a salt thereof.
8. The method, according to claim 1 , wherein said dipeptide, or salt thereof, is administered in an aqueous formulation.
9. A method for the treatment of a condition that is selected from retinopathy of prematurity, diabetic retinopathy, vascular proliferative retinopathy, and proliferation of abnormal vascularization, in a human patient who has one of these conditions and is thus in need of such treatment, the method comprising enterally administering to the patient a composition comprising arginyl-glutamine dipeptide, or a salt thereof, in an amount that is sufficient to treat the condition.
