  Synthesis of 2-Amido-2,3-dihydro-1H-phenalene Derivatives as New Conformationally Restricted Ligands for Melatonin Receptors

  摘要：

  Tetrahydroanthracene, tetrahydrophenanthrene, and tetrahydrophenalene moieties were used to design novel constrained melatoninergic agents. Compounds 1 and 2 were synthesized from the cyclization of the aryl succinic acids 6a,b followed by catalytic reduction, Curtius degradation to the amino derivatives, and acetylation. The phenalene derivatives 3 were prepared by cyclization of the aza lactones of the corresponding alpha-N-acetyl amino acids. The ketone derivatives were reduced directly by catalytic hydrogenation to produce the compounds 3. The different compounds were evaluated in vitro in binding assays using 2-[I-125]iodomelatonin and chicken brain membranes. Melatonin and 2-acetamido-8-methoxytetralin were used as the reference compounds. The results showed the superiority of the dihydrophenalene framework 3 over tho se of tetrahydro anthracene and tetrahydrophenanthrene. 3a had relatively good affinity for melatonin receptors (K-i = 28.7 nM). Introduction of an additional methoxy group gave a derivative (3c) with nanomolar affinity (K-i = 0.7 nM), confirming the existence of a secondary binding site in the receptor which has been described previously. An increase in the affinity was also observed with the propionamido derivative 3e (K-i = 6.0 nM). The potential agonist properties of the compound 3e were evaluated on the dermal melanocytes of Xenopus laevis tadpoles. At the concentration of 2.3 nM (5 x K-i), melatonin gave melanophore index value of 1. Similarly to melatonin, 3e was shown to be a potent agonist of the melanosome aggregation.
