Abstract:
TYK2 (Tyrosine Kinase 2), a crucial member of the JAK (Janus Kinase) family, plays a pivotal role in mediating the signaling of various immune-related cytokines. Traditional JAK inhibitors, due to their low selectivity, are often associated with risks of adverse effects and may lead to reduced therapeutic efficacy over time with prolonged use. Selectively targeting TYK2 provides a promising therapeutic strategy to address these challenges by minimizing off-target effects and preserving the function of other JAK family members. In this review, we explore the structure and biological features of TYK2, the JAK/STAT (Signal Transducers and Activators of Transcription) signaling pathway, and the therapeutic potential of TYK2 inhibitors for autoimmune diseases and cancer. We also provide an overview of the progress of TYK2 small molecule inhibitors, including single-target, dual-target, and TYK2 degraders. Furthermore, we explore the challenges in TYK2 research and development and propose potential strategies to overcome these challenges, providing valuable insights for the development of TYK2 inhibitors.
