The invention discloses an iodipin and targeted drug compound. The iodipin and targeted drug compound comprises iodipin and a targeted drug, and the targeted drug is targetingly gathered on an in-vivotumor area through the iodipin. The iodipin is adopted as an embolization agent or an area targeting agent, the targeted drug is taken into the tumor area, the targeted drug is targetingly gathered on the tumor area rather than acts on other non-tumor organ tissue, and therefore the side effects of the targeted drug are relieved. Some targeted drugs with an angiogenesis restraining function can restrain angiogenesis caused by inflammatory factor releasing caused by iodipin embolism, and therefore hyperplasia of residual tumor tissue causd by iodipin embolism embolism is restrained.

The invention discloses an application of a blocker with integrin affinity and bonding capability and MMPs (matrix metalloproteinases) inhibiting capability, and belongs to the field of medicines. The application comprises a polypeptide I (Arg-Gly-Asp-Gly-Gly-Gly-Gly-Pro-(D-Pyr)-(D-Cys)-Bip-Arg-Gly-Glu) and a polypeptide II (Pro-(D-Pyr)-(D-Cys)-Bip-Arg-Gly-Glu-Gly-Gly-Gly-Gly-Arg-Gly-Asp), wherein the polypeptide I is modified with an integrin ligand sequence (Arg-Gly-Asp-Gly-Gly-Gly-Gly); two types of blood vessel inhibiting polypeptides with integrin affinity and bonding capability are formed. The application has the advantages that because of the targeting property of an RGD (arginine-glycin-aspartate) sequence, the polypeptides can be targeted to the new blood vessel endothelium of the RA (rheumatoid arthritis) pannus forming process, the forming of MMPs (matrix metalloproteinases) and the new blood vessel can be inhibited, and the effect of preventing or treating the blood vessel and inflammatory diseases are realized; the polypeptides can be applied to the treatment of the blood vessel and inflammatory diseases, such as arthritis, inflammation, tumors, and eye diseases.

The invention discloses the application of a beta-2-glucoprotein-I of the natural type, the cracking type or the V structure domain deletion mutant type in preparing for a novel drug of restraining the angiogenesis. The test testifies that the natural type beta-2-glucoprotein-I (n beta₂GPI), the cracking type beta-2-glucoprotein-I (c beta₂GPI) and the V structure domain deletion mutant type beta-2-glucoprotein-I (DI-IV) can restrain the angiogenesis of the endothelial cell. The functional mechanism of the invention is that the invention influences the expression and photophosphorylation of an accepter of an endothelial cell growth factor to retain the signal conducting path of the accepter and retain the lower fifty genetic expressions and further retain the multiplication, the migration and the angiogenesis of the endothelial cell. The invention can provide novel preventing and remedying measures for clinical treatment of the diseases of the angiogenesis, such as the multiplication type retina lesion of the diabetes etc.

The invention discloses an anti-tumor vascular drug sustained-release embolization microsphere for malignant tumor interventional therapy, which is made of a degradable or non-degradable material and is internally loaded with an anti-tumor vascular drug for resisting tumor vessels, tumor angiogenesis and tumor angiogenesis, and the drug comprises an antibody or small molecule compound drug. The growth of original blood vessels of tumor tissues and the angiogenesis of the tumor tissues can be resisted or inhibited, so that the formation of collateral circulation of the tumor tissues is inhibited, and the growth, metastasis and relapse of tumors are inhibited. According to the present invention, the tumor blood vessel is inhibited while the tumor tissue blood supply is embolized and blocked, the tumor angiogenesis and the tumor collateral circulation formation are inhibited, and the tumor recurrence and the tumor metastasis are effectively avoided. The anti-tumor vascular drug is slowly released in a tumor area, the high drug concentration can be kept at the tumor part for a long time, the drug concentration in systemic circulation is not too high, the drug utilization rate is increased, and the side effects of the drug are relatively reduced.

The invention discloses application of a prostaglandin E2 receptor targeting drug in treatment of diabetic retinopathy. The level of PGE2 in the vitreous fluid of a diabetic patient rises abnormally,and PGE2 needs to play a role through an EPR receptor. Therefore, when an EP4R inhibitor (AH23848) is injected into the vitreous cavity for treatment, the EP4R inhibitor inhibits the expression of anEP4R receptor, so that the PGE2 effect is inhibited, the expression of NLPR3 and IL-1 beta mRNA levels in RMECs is reduced, the damage of retinal microvascular endothelial cells in DR is reduced, andthe effect of treating proliferative diabetic retinopathy is achieved. Through detection, analysis and summarization of the inventor, the inventor analyzes and determines the pathogenesis of DR and determines that the development of DR is mediated by various inflammatory factors, fibrosis factors and angiogenesis promoting factors, so that based on the treatment target of the targeted prostaglandin E2 receptor, the drug for effectively treating DR is screened and the use method of the drug is provided.
