Abstract
Description
[0001] This application is a divisional application of the Chinese invention patent application with application number 202111074627.8, application date September 14, 2021, and invention name “Compounds for inhibiting programmed cell death and preparation methods thereof”. Technical Field
[0002] The present invention provides an inhibitor for inhibiting programmed cell necrosis, and particularly relates to a preparation method thereof and a method and use thereof for treating and preventing inflammatory and degenerative diseases. Background Art
[0003] Programmed cell death is a highly inflammatory form of cell death that can be induced by a variety of promoting factors, such as necrosis factor (TNF) and FAS ligand. This process can occur in a variety of cells and is considered to be the main mode of cell death under pathological conditions. It is directly related to a variety of inflammatory diseases and degenerative diseases. These diseases include neurodegenerative diseases, stroke, coronary heart disease, myocardial infarction, retinal degenerative diseases, inflammatory bowel disease, kidney disease, liver disease, and many other related diseases.
[0004] RIPK1 (receptor interacting protein kinase 1) participates in many key intracellular inflammatory signaling pathways, including not only programmed cell necrosis (necroptosis), but also scientific experiments have confirmed that the protein can cause a wide range of inflammatory cell processes by causing cell rupture. RIPK1 is a major regulator of NF-κB signaling and cellular determinants of death response, among which NF-κB signaling responds to a wide range of inflammatory and pro-death stimuli in human diseases.
[0005] Therefore, RIPK1 inhibitors can provide more effective inhibition of programmed cell necrosis for the prevention and treatment of inflammatory and degenerative diseases related thereto. Summary of the invention
