Design and Synthesis of Naphthalenic Dimers as Selective MT1 Melatoninergic Ligands
摘要:
We report the synthesis and binding properties at MT1 and MT2 receptors of the first example of agomelatine (N-[2-(7-methoxynaphth-1-yl)ethyl] acetamide) dimers in which two agomelatine moieties are linked together through their methoxy substituent by a polymethylene side chain according to the "bivalent ligand" approach. Some of these compounds behave as MT1-selective ligands. The most selective one (5) behaves as an antagonist.
