108 compounds was then synthesised from 12 arylalkyl amines and nine carboxylic acids. The compound mixtures were evaluated on chicken brain melatonin and recombinant human mt1 and MT2 receptors. Deconvolution of the most potent mixture demonstrated the superiority of 3-methoxy and 2,5-dimethoxy substitution on the phenyl ring with isopropyl, propyl and ethyl amido chains. Several compounds with nanomolar

A series of unsubstituted and methoxy-substituted 2-amidotetralins (4a-q) was prepared and evaluated for their ability to compete for 2-[I-125]iodomelatonin binding to chicken retinal membranes and for their potency to inhibit the calcium-dependent release of [H-3]dopamine from rabbit retina. The lead compound, 2-acetamido-8-methoxytetralin (4j), showed a moderate affinity (K(i) = 46 nM) and potency (IC50 = 1.4 nM) at the melatonin receptor. The structural requirements necessary for optimal agonistic activity at the melatonin receptor are as follows. First, the amido group, which should have a small, nonbranched alkyl group, is essential for affinity, and second, the methoxy substituent at the 8-position of the 2-amidotetralin ring is essential for optimal agonistic activity at the melatonin receptor. We concluded that this series of unsubstituted and methoxy-substituted 2-amidotetralins constitutes a class of nonindolic melatonin-like agents that can be used as pharmacological tools to further characterize melatonin receptors and to elucidate the mode of action of melatonin.
