Abstract

PROBLEM TO BE SOLVED: To obtain the subject inhibitor capable of inhibiting the propagation of human capillary endothelial cells by making the inhibitor include a specified imidazole derivative as an active ingredient. SOLUTION: This inhibitor against arterialization contains an imidazole derivative of formula I [one of A and B is a group of formula II (R<1> is H, a halogen, OH or the like; R<2> and R<3> are each H, a halogen, a lower alkyl or the like), and the other is carbamoyl; R<4> is a lower alkoxycarbonyl] or a pharmacologically acceptable salt thereof as an active ingredient. The inhibitor has, for example, an administration form such as a powder, a tablet, a capsule, an ointment and an injection forms, and can be obtained optionally by preparing a preparation by mixing with, diluting with or dissolving in a vehicle, a disintegrator, a binder, a lubricant or the like. The daily dose is 0.1-1,000 mg per adult in a case of oral administration and 0.01-300 mg per adult in the case of parenteral administration, and can be administered by dividing the daily dose to one or several dosages.

BACKGROUND OF THE INVENTION Angiogenesis generally involves digestion and destruction of the basement membrane of blood vessels by proteases, migration and proliferation of vascular endothelial cells, formation of a lumen by differentiation of vascular endothelial cells, and reconstitution of blood vessels. It is a phenomenon. Angiogenesis occurs physiologically during luteal formation and placental formation, and under pathological conditions, it appears in the above-mentioned diseases. For example, in retinopathy, the retinal tissue intervening between the existing basement membrane around the retinal vessels and the vitreous is first destroyed,
Next, the vascular endothelial cells that make up the existing blood vessels migrate from the gap of the destruction site of the retinal tissue, the vascular endothelial cells proliferate so as to fill the gap between the migrated vascular endothelial cells, and then the vascular endothelial cells migrated to the retinal vitreous body Angiogenesis progresses by reconstituting blood vessels.

Angiogenesis is related to various diseases, for example, it is deeply involved in the onset or progression of the above diseases. Therefore, for the prevention or treatment of these diseases,
Intensive research has been actively pursued to search for substances that inhibit angiogenesis. For example, examples of angiogenesis inhibitors include microbial metabolite fumagillin analogs having an inhibitory action on vascular endothelial cells, tetracycline antibiotics having an action of inhibiting collagenase activity, and binding of heparin-binding angiogenic factors to receptors.

[0010] At present, there is no clinically satisfactory drug as an angiogenesis inhibitor, so that there is no sufficient treatment for the above-mentioned diseases relating to angiogenesis. Especially in diabetic retinopathy, regression of new blood vessels is not observed unless surgical treatment is performed, and visual impairment due to bleeding from the new blood vessels is a problem, so it is excellent for angiogenesis There is a great need for the development of effective drugs.
