  Synthesis of benzocycloalkane derivatives as new conformationally restricted ligands for melatonin receptors

  摘要：

  Benzocycloalkane derivatives 1-4 were synthesized as new conformationally restricted melatoninergic ligands. They were prepared by rite reaction of the ketones 5 with diethylcyanophosphonate and the reduction of the corresponding cyano compounds or by the Wittig reaction and Curtius degradation to obtain the amines 8. The 1-Cyanobenzocyclobutane derivative was obtained by the benzyne cyclisation reaction. The amines 8 were acylated with acetyl, propionyl or butyryl groups. The affinity of the compounds for chicken brain melatonin receptors was evaluated using 2-[I-125]-iodomelatonin as the radioligand The indanyl (2b,c) tetralin (3a-c) and benzocycloheptane (4c) derivatives were potent compounds with nanomolar affinity and an important enantioselectivity of the receptor was observed with the (+) enantiomers 2b and 3b.

  We synthesized a novel series of benzocycloalkene derivatives and evaluated their binding affinities to melatonin receptors. To control the spatial position of the amide group, one of the important pharmacophores, we incorporated an endo double bond, an exo double bond (E- and Z-configurations), and a chiral center (R- and S-configurations) at position 1. The indan derivatives with the S-configuration at position 1 were the most promising in terms of potency and selectivity for the human melatonin receptor (MT, site), while compounds with the R-configuration showed little potential. Our next attempt was to investigate the most favorable conformation of the methoxy group, the other important pharmacophore for binding to the MT, receptor. The introduction of a methyl group at position 5 of the indene ring conserved affinity; however, at position 7, it caused a decrease in affinity. These results suggested that the substitution at position 7 forced the methoxy group to adopt an unfavorable orientation. The optimization of the condensed ring size and substituents led to (S)-8d [(S)-N-[2-(2,3-dihydro-6-methoxy-1H-inden-1-yl)ethyl]propionamide], which had high affinity for the human MT3 receptor (K-i = 0.041 nM) but no significant affinity for the hamster MT3 receptor (K-i = 3570 nM). In addition, a practical synthetic method of chiral N-[2-(2,3-dihydro-1H-inden-1-yl)ethyl]-alkanamides employing asymmetric hydrogenation with (S)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl-Ru has been established.
