  Bicyclic melatonin receptor agonists containing a ring-junction nitrogen: Synthesis, biological evaluation, and molecular modeling of the putative bioactive conformation

  摘要：

  Employing 1,3-dipolar cycloaddition for the synthesis of the 7a-azaindole nucleus, analogues of melatonin have been synthesized and tested against human and amphibian melatonin receptors. Introducing a phenyl substituent ill position 2 of the heterocyclic moiety significantly increased binding affinity to both the MT1 and MT2 receptors. Shifting the methoxy group from position 5 to 2 of the 7a-azaindole ring led to a substantial reduction of MT1 binding when MT2 recognition was maintained. We theoretically investigated the hypothesis whether the 2-methoxy function of the azamelatonin analogue 27 is able to mimic the 5-methoxy group of the neurohormone by directing its 2-methoxy function toward the methoxy binding site. DFT calculations and experimental binding differences of analogue compounds indicate that the energy gained by forming the methoxy-specific hydrogen-bond interaction should exceed the energy required for adopting ail alternative conformation.

  We have made a novel series of pyrazolo[1,5-a]pyridines as PI3 kinase inhibitors, and demonstrated their selectivity for the p110 alpha isoform over the other Class Ia PI3 kinases. We investigated the SAR around the pyrazolo[1,5-a] pyridine ring system, and found compound 5x to be a particularly potent example (p110 alpha IC50 0.9 nM). This compound inhibits cell proliferation and phosphorylation of Akt/PKB, a downstream marker of PI3 kinase activity, and showed in vivo activity in an HCT-116 human xenograft model.
