Abstract

The invention discloses a compound having a structure represented by formula (I) and used for a discoidin domain receptor micro-molecule inhibitor, or its pharmaceutically acceptable salt or stereo isomer or prodrug molecule. The above compounds can effectively inhibit the activity of the discoidin domain receptor, and can be used for preparing drugs for preventing and treating inflammations, liver fibration, kidney fibration, lung fibration, skin scars or atherosclerosis.

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and in particular relates to a compound used as a discoid domain receptor small molecule inhibitor and application thereof. Background technique [0002] Discoidin domain receptors (DDRs) are a subfamily of transmembrane receptor tyrosine protein kinases, including two subtypes DDR1 and DDR2. In the tyrosine kinase region, these two subtypes have 89% homology. Discoid domain receptors are structurally distinct from other receptor tyrosine kinases in that they have two extracellular discoid structures. DDR1 is mainly expressed in epithelial cells of lung, kidney, colon and brain, while DDR2 is mainly expressed in mesenchymal cells such as fibroblasts, myofibroblasts and smooth muscle cells of kidney, skin, lung, heart and connective tissue. Much evidence has shown that aberrant expression of discoid receptors is associated with various disease processes, such as inflammation, liver fibrosis...
