The present invention describes linking a therapeutic agent to a compound
which is known to be naturally concentrated in a tissue affected by, or
that is causing, a disease, to create a prodrug for treatment of the
disease. Embodiments of the present invention include a new class of
carotenoid-linked drugs to treat such blinding retinal disease such as
age-related macular degeneration, retinoblastoma, and diabetic macular
edema. For example, the present invention comprises a method for the
treatment of a disorder of the eye comprising linking a therapeutic agent
to a xanthophyll carotenoid to create a prodrug, and administering a
therapeutically effective amount of the prodrug to an individual in need
of treatment. Provided are prodrugs for treatment of retinoblastoma,
cystoid macular edema (CME), exudative age-related macular degeneration
(AMD), diabetic retinopathy, diabetic macular edema, or inflammatory
disorders.
