NOD-IN-1 is a potent and selective inhibitor of the NOD1 signaling pathway, which plays a key role in innate immune responses. It is primarily used in research to modulate inflammatory processes associated with NOD1 activation. By inhibiting NOD1, this compound helps reduce the production of pro-inflammatory cytokines, making it a valuable tool in studying inflammatory diseases such as inflammatory bowel disease, asthma, and certain autoimmune conditions. It is also employed in cellular and molecular studies to dissect the role of NOD1 in host-pathogen interactions and immune regulation. Due to its specificity, NOD-IN-1 allows for targeted investigation of NOD1-dependent pathways without affecting related signaling mechanisms like NOD2 or TLRs.
