Used in research to modulate casein kinase 1 (CK1) activity, this inhibitor helps study cellular processes such as circadian rhythm regulation, Wnt signaling, and DNA damage response. It is applied in biochemical assays to explore kinase-dependent pathways and has potential in developing therapies for neurodegenerative diseases, cancer, and mood disorders. Its role in disrupting CK1-mediated phosphorylation makes it valuable for understanding disease mechanisms and screening drug candidates.
