Abstract:
:Novel heterodimer analogues of melatonin were synthesized, when agomelatine (1) and various aryl units are linked via a linear alkyl chain through the methoxy group. The compounds were tested for their actions at melatonin receptors. Several of these ligands are MT(1)-selective with nanomolar or subnanomolar affinity. In addition, while most of the derivatives behave as partial agonists on one or both receptor subtypes, N-[2-(7-{4-[6-(1-methoxycarbonylethyl)naphthalen-2-yloxy]butoxy}naphthalen-1-yl)ethyl]acetamide (36), a subnanomolar MT(1) ligand with an 11-fold preference over MT(2) receptors, is a full antagonist on both receptors. Our results also confirm that the selectivity seen for the MT(1) receptor arises predominantly from steric factors and is not a consequence of the bridging of melatonin receptor dimers.
