Design, synthesis, and pharmacological effects of structurally simple ligands for MT1 and MT2 melatonin receptors
摘要:
A series of phenoxyalkyl and phenylthioalkyl amides were prepared as melatoninergic ligands. Modulation of affinity of the newly synthesized compound by applying SARs around the terminal amide moiety, the alkyl chain, and the methoxy group on the aromatic ring provides compounds with nanomolar affinity for both melatonin receptor subtypes. Affinity towards MT1 and MT2 receptors were modulated also exploiting chirality. The investigation of intrinsic activity revealed that all the tested compounds behave as full or partial agonists.

A novel series of melatonin receptor ligands, characterized by a N-(substituted-anilinoethyl)amido scaffold, along with preliminarystructure-activityrelationships (SARs), is presented. MT1 and MT2 receptor binding affinity and intrinsic activity have been modulated by the introduction of different substituents on the aniline nitrogen, on the benzene ring, and on the amide side chain.
