APPLICATIONS OF HPK1 KINASE INHIBITOR IN PREVENTING AND/OR TREATING ANIMAL PATHOGEN INFECTION

摘要

Applications of an HPK1 kinase inhibitor in preventing and/or treating an animal pathogen infection. The HPK1 kinase inhibitor is a small molecule HPK1 kinase inhibitor, specifically, the compound of formula I or a pharmaceutically acceptable salt, a stereoisomer, an ester, a prodrug, a solvate, or a deuterated compound of same. The HPK1 kinase inhibitor effectively treats diseases (such as feline infectious peritonitis) caused by infection of animal pathogens (specifically viruses, such as coronaviruses), improves animal survival, and provides enhanced commercial value and application prospects in the field of animal antiviral (specifically viruses, such as coronaviruses) medicaments.
