Compound and crystals thereof

Abstract

The invention discloses a pyrimidine compound of a structural formula A. The structural formula A is shown below. The pyrimidine compound can be used for preparing medicaments for treating diseases associated with vasculogenesis, in particular medicaments for treating tumor, age-related macular degeneration or autoimmune diseases.

Description

technical field The invention belongs to the field of pharmacy and provides a pyrimidine compound N-[2-(dimethylamino)ethyl]-[3-[4-(2-methyl-1H-indole-5-oxyl)pyrimidine- 2-Amino]phenyl]methanesulfonamide and its medicinal use and crystal form, in particular to a kinase-inserted-region receptor (KDR) inhibitor for treating diseases related to angiogenesis. Background technique Angiogenesis is the physical process of growing new blood vessels from pre-existing blood vessels. It often occurs when a healthy body uses it to heal a wound, such as restoring blood flow to injured tissue in the hand. Excessive vascular proliferation can be initiated by some specific pathological conditions, such as tumors, age-related macular degeneration (Age-related Macular Degeneration, AMD), rheumatoid arthritis, psoriasis and so on. Therefore, under these conditions, new blood vessels often nourish pathological tissues and destroy normal tissues. For example, in tumors, new blood vessels can a...
