The present invention is drawn to methods and compounds for photodynamic therapy (PDT) of a target tissue or compositions in a mammalian subject, using a light source that preferably transmits light to a treatment site transcutaneously. The method provides for administering to the subject a therapeutically effective amount of a targeted substance, which is either a targeted photosensitizing agent, or a photosensitizing agent delivery system, or a targeted prodrug. This targeted substance preferably selectively binds to the target tissue. Light at a wavelength or waveband corresponding to that which is absorbed by the targeted substance is then administered. The light intensity is relatively low, but a high total fluence is employed to ensure the activation of the targeted photosensitizing agent or targeted prodrug product. Transcutaneous PDT is useful in the treatment of specifically selected target tissues, such as vascular endothelial tissue, the abnormal vascular walls of tumors, solid tumors of the head and neck, tumors of the gastrointestinal tract, tumors of the liver, tumors of the breast, tumors of the prostate, tumors of the lung, nonsolid tumors, malignant cells of the hematopoietic and lymphoid tissue and other lesions in the vascular system or bone marrow, and tissue or cells related to autoimmune and inflammatory disease.

A method for treating abnormal blood vessel growth and proliferation is disclosed. Members of the hypocrellin class of compounds such as hypocrellin A, hypocrellin B, and / or amino-substituted derivatives of hypocrellin B are administered and photoactivated with photodynamic therapy. The method may be used, for example, to treat ocular blood vessel proliferation as occurs with macular degeneration.

The present invention relates to pharmaceutical compositions comprising therapeutically effective amounts of recombinant troponin C, I or T subunits for the treatment of diseases or disorders involving abnormal angiogenesis.

Vanadium compounds for inhibiting angiogenesis useful for treating or preventing diabetic retinopathy, hemangiomas, cancers with abnormal blood vessel supply, restenosis following vascular injury, and the like.

Methods and compositions are provided for the treatment of diseases such as exudative macular degeneration, diabetic retinopathy, retinopathy of prematurity, choroidal neovascularization, retinal neovascularization, iris neovascularization, corneal neovascularization, ocular tumors, and other disorders of the eye, cancer, and inflammatory disorders. The method involves administering a conjugate, referred to as fVIIPD, containing a photosensitizer and a targeting molecule such as factor VII (“fVII”), fVIIa, or modified fVII, which binds with high affinity and specificity to tissue factor (TF). TF is more highly expressed, abnormally expressed or specifically expressed on endothelial cells lining the luminal surface of pathological neovasculature, than on normal vasculature, thus providing a specific and accessible therapeutic target. Following administration of fVIIPD, the compound specifically binds to the pathological neovasculature of the eye by interaction of the targeting molecule with TF expressed by endothelial cells within abnormal blood vessels. The photosensitizer may then be activated with a non-thermal laser light for selective destruction of abnormal vasculature.

The invention discloses a blood vessel abnormity detection method and device and a computer readable storage medium. The method comprises the steps that obtaining a diameter curve of a blood vessel; performing curve fitting processing on the diameter curve to obtain a blood vessel characteristic curve; and screening the abnormal blood vessel area according to the diameter curve and the blood vessel characteristic curve. By implementing the method and the device, the accuracy of blood vessel abnormity detection is improved.

Disclosed herein are methods for treating ocular neovascular disease using anti-VEGF therapy in combination with a second therapy that inhibits the development of ocular neovascularization or destroys abnormal blood vessels in the eye, such as photodynamic therapy.

In a method for treating an affected skin region of a patient having a skin disorder, a vasodilation composition is applied to an affected skin region of a patient, the affected skin region exhibiting a skin disorder characterized by at least one abnormal blood vessel, and the affected skin region is then treated so as to non-invasively disrupt tissue architecture, e.g., by inducing ischemia, of the at least one abnormal blood vessel. A vasoconstriction composition can then be applied to the skin region to cause vasoconstriction of the at least one blood vessel in order to promote healing.

The present invention discloses compounds according to Formula I:wherein R1, R2, R3a, R3b, X, Y1, Y2, Y3, and Z are as defined herein.The present invention relates to compounds, methods for their production, pharmaceutical compositions comprising the same, and methods of treatment using the same, for the prophylaxis and / or treatment of inflammatory diseases, autoinflammatory diseases, autoimmune diseases, proliferative diseases, fibrotic diseases, transplantation rejection, diseases involving impairment of cartilage turnover, congenital cartilage malformation, diseases involving impairment of bone turnover, diseases associated with hypersecretion of TNFα, interferons, IL-6, IL-12 and / or IL-23, respiratory diseases, endocrine and / or metabolic diseases, cardiovascular diseases, dermatological diseases, and / or abnormal angiogenesis associated diseases by administering the compound of the invention.

The invention discloses application of Withaferin A in preparing a drug for treating a fundus ischemic disease. Experiments show that the Withaferin A can inhibit the fundus ischemic disease from theperspective of pathogenesis through two mechanisms that 1, oxidative stress cell necrosis and apoptosis caused by ischemia are significantly reduced; 2, targeted inhibition of a vascular endothelial growth factor and a signaling pathway of a receptor (VEGF-VEGFR2) of the vascular endothelial growth factor is achieved, and the pathological microvascular hemorrhage leakage, abnormal blood vessel growth and other symptoms are ameliorated. The Withaferin A significantly relieves the symptoms of the fundus ischemic disease and inhibits the generation and development of the disease through the dualeffects of the two mechanisms. The Withaferin A as a small molecule targeting compound has a stable and safe chemical structure and can penetrate through a blood-eye barrier, therefore the WithaferinA has a broad application prospect in the fundus ischemic disease.

Fusion proteins containing a PDGF binding portion, a VEGF binding portion, and an Fc antibody region are described. Also described are nucleic acids encoding the fusion proteins, compositions comprising the fusion proteins, and methods of using the fusion proteins for treating or preventing clinical conditions characterized by abnormal angiogenesis, such as vascular permeability, edema or inflammation.

The present invention relates to a dual-targeting antibody targeting stem cell factor (SCF) and galectin-1 and a composition for preventing or treating angiogenesis-related diseases comprising the same. The present invention provides a dual-targeting antibody derived from a human monoclonal antibody which can effectively inhibit angiogenesis by simultaneously neutralizing SCF and galectin-1 involved in angiogenesis, and a pharmaceutical composition for preventing or treating angiogenesis-related diseases comprising the antibody. The dual-targeting antibody according to the present invention can effectively prevent or treat angiogenesis-related diseases by simultaneously neutralizing two targets involved in angiogenesis wherein the angiogenesis-related diseases cause hemorrhaging by blood vessels changing due to abnormal angiogenesis and thus increasing the permeability thereof.

The present invention relates to mouse antibodies that bind to angiopoietin-2 (Ang2), humanized anti-Ang2 antibodies derived therefrom, and the use thereof.
