ANAT inhibitor-2 is a potent inhibitor of arylalkylamine N-acetyltransferase (ANAT) enzymes, used primarily in research settings to study cellular processes involving these enzymes. By inhibiting ANAT activity, it helps in understanding the regulation of melatonin synthesis and circadian rhythms. Potential applications include investigating sleep disorders and developing therapies for conditions linked to melatonin dysregulation. It is also explored in cancer research due to its role in modulating metabolic pathways.
