Numerous functions of the neurohormone melatonin are mediated through activation of the G - protein - coupled receptors MT₁⁻ and MT₂. Elucidation of the pathophysiological function of the MT₁ receptor has been hampered mainly by the limited availability of selective full agonist and full antagonist for this receptor subtype. Design and synthesis of selective MT₁ receptor ligands with higher affinity and selectivity may contribute to better understanding of physiological functions mediated by MT₁ receptors
