The invention relates to a nitric acid ester drug for inhibiting the regeneration of blood vessels. The drug is the compound 1, ester or salt of the compound with the following general formula: T-(B-O-NO2)t1, wherein t1 is 1 or 2; T-H is a steroids compound; T is a residual steroids radial of the compound 1 after removing H, and T and H are connected in the form of O-H, namely connecting an oxygen atom on T and H, to form a hydroxide radical The compound is used for preparing the drug for treating tumor and ocular neovascularizationdisease.
An improved method to treat conditions of the eye characterized by ocular neovascularization is provided in which patients are given and initial photodynamic therapy (PDT) treatment to destroy the neovasculature, and then are re-evaluated at least twice during the following 6 months, and retreated as necessary. Preferably, three retreatments are provided.
Formulations and methods useful to reduce ocular neovascularization (new blood vessels in the cornea, retina, conjunctiva, and / or choroid) are disclosed. According to the invention the formulation will include tetracycline or a derivative thereof including chemically modified tetracyclines (CMT) which inhibit matrix metalloproteinase (MMP) activity at a substantially neutral pH in a pharmaceutically acceptable form suitable for delivery to the eye in an amount and for a duration sufficient to reduce ocular neovascularization. According to the invention the formulations are preferably in pharmaceutically acceptable formulations for topical ocular application, ocular injection, or ocular implantation, and may be contained in liposomes or slow release capsules.
The present invention relates to compositions and methods for treating diabetic retinopathy and other ocular neovascularization diseases. In one embodiment, the composition comprises at least two different siRNA duplexes and a pharmaceutically acceptable carrier. One of the duplexes binds to an mRNA molecule that encodes VEGF, and the other binds to an mRNA molecule that encodes VEGFR2. In another embodiment, the composition further comprises an siRNA duplex that binds to an mRNA molecule that encodes TGFβ1.
