SC-396658 is primarily used in biochemical and pharmacological research as a selective inhibitor targeting specific signaling pathways involved in inflammation and immune responses. It has been investigated for its potential to modulate cellular activity in models of autoimmune diseases, showing promise in reducing pro-inflammatory cytokine production. Due to its high selectivity and potency in cellular assays, it serves as a valuable tool compound for studying kinase-dependent processes and validating therapeutic targets in preclinical drug development. Its application is largely confined to laboratory settings for mechanistic studies rather than clinical use.
