IQ-1 is primarily used in research settings to study cellular signaling pathways, particularly those involving the JNK (c-Jun N-terminal kinase) pathway. It functions as an inhibitor of JNK, which plays a significant role in regulating inflammation, cell stress, and apoptosis. By modulating this pathway, IQ-1 helps researchers investigate potential therapeutic strategies for diseases such as cancer, inflammatory disorders like arthritis, and neurodegenerative conditions. Its application is particularly valuable in understanding the molecular mechanisms underlying these diseases and in developing targeted treatments.
