PROTAC IRAK4 degrader-3 is primarily used in the field of targeted protein degradation. It is specifically designed to degrade IRAK4, a kinase involved in inflammatory signaling pathways. This makes it a valuable tool in research focused on understanding and treating diseases where IRAK4 plays a critical role, such as autoimmune disorders, chronic inflammation, and certain cancers. By selectively degrading IRAK4, it helps in studying the downstream effects of its inhibition and exploring potential therapeutic strategies. Additionally, it serves as a prototype for developing novel PROTAC-based drugs that can target other disease-related proteins.
