  摘要：

  钯催化的芳基氯化物、溴化物和碘化物的直接芳基化已被应用于通过与苯并二恶唑、吡啶 N-氧化物和吡嗪 N-氧化物反应制备新的阿朴啡类似物，包括 C2 取代的阿朴啡。直接芳基化在这些多样化反应中的成功应用突出了其不仅在收敛合成中而且在发散合成中的效用。我们还描述了 (R)-nornuciferine 和 (R)-nuciferine 的对映选择性合成，采用催化不对称转移氢化以高产率和优异的对映体过量。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)

  Methanolic extracts from the flower buds and leaves of sacred lotus (Nelumbo nucifera, Nymphaeaceae) were found to show inhibitory effects on melanogenesis in theophylline-stimulated murine B16 melanoma 4A5 cells. From the methanolic extracts, a new alkaloid, N-methylasimilobine N-oxide, was isolated together with eleven benzylisoquinoline alkaloids. The absolute stereostructure of the new alkaloid was determined from chemical and physicochemical evidence. Among the constituents isolated, nuciferine, N-methylasimilobine, (-)-lirinidine, and 2-hydroxy-1-methoxy-6a, 7-dehydroaporphine showed potent inhibition of melanogenesis. Comparison of the inhibitory activities of synthetic related alkaloids facilitated characterization of the structure-activity relationships of aporphine-and benzylisoquinoline-type alkaloids. In addition, 3-30 mu M nuciferine and N-methylasimilobine inhibited the expression of tyrosinase mRNA, 3-30 mu M N-methylasimilobine inhibited the expression of TRP-1 mRNA, and 10-30 mu M nuciferine inhibited the expression of TRP-2 mRNA.

  This study was aimed to synthesize novel 2-(2-bromophenyl)-N-phenethylacetamides and benzylisoquinoline (BIQ) derivatives to be evaluated as antidepressant-like agents in mice. The phenethylacetamides derivatives were synthesized by coupling aromatic amides to the backbone of 2-bromophenylacetyl chloride. The synthesis of BIQ was achieved by the reaction between synthesized phenethylacetamides and 2-chloropyridine. The structures of compounds were established mainly by 1D and 2D NMR spectra. Those compounds obtained with moderate to good yields were evaluated as antidepressant-like agents in the forced swim test and the open field paradigms in mice. The possible mechanism of those active derivatives was explored by antagonist experiments in combination with p-chloro-phenylalanine methyl ester, reserpine, sulpiride, and dopamine D1 antagonist SCH23390. Also, MAO A and B inhibition assays were performed. Docking studies between the human dopamine D3 receptor and the higher active compound were performed. The results showed that the (2-bromophenyl)-(3,4-dihydroisoquinoline-1-yl)methanone (4a) presented the most potent antidepressant-like effects without modifying the ambulatory activity of experimental mice. Antagonist experiments showed that 4a acted on the serotonergic and dopaminergic receptors. Docking studies indicated a strong affinity between the human dopamine D3 receptor and 4a. Our results showed that BIQ 4a has an antidepressant-like effect that is possibly mediated by an interaction with the presynaptic serotonin receptors and dopaminergic, D1, D2, and D3, receptors. This study highlights the pharmacological potential of halogenated BIQs in the treatment of some depressive disorders.
