Abstract

Serotonin N -acetyltransferase (arylalkylamine N -acetyltransferase, AANAT) is an enzyme that catalyses the first rate limiting step in the biosynthesis of melatonin (5-methoxy- N -acetyltryptamine). Different physiopathological disorders in human may be due to abnormal secretion of melatonin leading to an inappropriate exposure of melatonin receptors to melatonin. For that reason, we have designed, synthesized and evaluated as inhibitors of human serotonin N -acetyltransferase, a series of compounds that were able to react with coenzyme A to give a bisubstrate analog inhibitor. Compound 12d was found to be a potent AANAT inhibitor (IC 50 =0.18 μM).
