Abstract: Provided are a 5-substituted indole 3-amide derivative, a preparation method and a use thereof, belonging to the field of medicine. A compound represented by formula I or a pharmaceutically acceptable salt thereof is provided. This type of compound can significantly inhibit the activity of RIPK1 kinase, has high selectivity and excellent safety, serves as a RIPK1 kinase inhibitor, and can be used as a potential therapeutic drug for inflammation, immune diseases, tumors and neurodegenerative diseases. TNF?-induced SIRS model experiments proved that the compound can inhibit a RIPK1 kinase in vivo. Pharmacokinetic results showed that this series of compounds has excellent pharmacokinetic properties, thus providing a novel strategy and means for disease treatments targeting RIPK1.
