  Synthesis and structure–activity relationships and effects of phenylpropanoid amides of octopamine and dopamine on tyrosinase inhibition and antioxidation

  摘要：

  Phenylpropanoid amides of octopamine (OA) 1a-1e and dopamine (DA) 2a-2e were synthesised and the structure-activity relationships (SARs) for antioxidant and tyrosinase inhibition activities were analysed. Among synthesised compounds, 2c, which contains two catechol moieties, exhibited the most DPPH radical-scavenging activity (EC50 = 16.2 +/- 2.41 mu M), and id exhibited significant tyrosinase inhibitory activity (IC50 = 5.3 +/- 1.8 mu M). Interestingly, with the same acid moiety, OA derivatives showed more inhibitory effect on tyrosinase than did compounds derived from DA, whereas DA derivatives were found to have higher antioxidant activity than compounds derived from OA. The relationship between their structures and their potencies, demonstrated in the current study, will be useful for the design of optimal agents. (C) 2012 Elsevier Ltd. All rights reserved.

• Formation of hydroxycinnamoylamides and α-hydroxyacetovanillone in cell cultures of Solanum khasianum

  Abstract In elicitor-treated photomixotrophic Solanum khasianum cell cultures, nine phenolic compounds accumulated in the cell culture medium. They were isolated and structurally identified as the cis - and trans -isomers of N - p -coumaroyloctopamine, N -feruloyloctopamine, N - p -coumaroyltyramine and N -feruloyltyramine as well as α-hydroxyacetovanillone. The cis -isomers of the hydroxycinnamoyl moieties

  摘要 在经过诱导剂处理的光混合营养型 Solanum khasianum 细胞培养物中，细胞培养基中积累了九种酚类化合物。它们被分离出来并在结构上被鉴定为 N-p-香豆酰氯多巴胺、N-阿魏酰氯多巴胺、N-p-香豆酰酪胺和 N-阿魏酰苯胺以及 α-羟基乙酰香草酮的顺式和反式异构体。羟基肉桂酰基部分的顺式异构体仅在培养物光照期间形成。根据化合物的不同，羟基肉桂酰胺在激发后 6 到 24 小时之间显示出最大值。化合物的减少很可能是过氧化物酶介导的反应。
