N-trans feruloyltyramine amide was successfully synthesized from 4-hydroxy-3-methoxycinnamic acid and tyramine hydrochloride in a one-step lipase catalysed reaction. The use of immobilized lipase, lipozyme TL IM as the catalyst in the reaction allowed simple isolation of the enzyme from the products and other components in the reaction mixture. N-feruloyltyramine amide was characterized using Fourier Transform Infrared (FTIR) Spectroscopy, Proton Nuclear Magnetic Resonance (1H NMR) and elemental analysis. Under optimized conditions 93.5% yield was obtained when the process was carried out for 48 h using a molar ratio of cinnamic acid:tyramine HCl, 6:1 at 40°C. In addition, a rapid simple and sensitive HPLC-UV method was developed for the determination of N-feruloyltyramine using an Rp-8 endcapped column. The optimum mobile phase used was acetonitrile:disodium hydrogen phosphate, 30:70(v/v.). N-feruloyltyramine amide was detected at a retention time of 12 min. The calibration curve was linear over the range of 5.2712.30 × 10-4 M with correlation factor r 0.9958. Consequently, the method was considered valid for quantitative analysis samples of N-trans-feruloyltyramine amide.

Wolfberry or Goji berry, the fruit of Lycium barbarum, exhibits health-promoting properties that leads to an extensive study of their active components. We synthesized a set of hydroxycinnamic acid amide (HCCA) compounds, including trans-caffeic acid, trans-ferulic acid, and 3,4-dihydroxyhydrocinnamic acid, with extended phenolic amine components as standards to identify and quantify the corresponding compounds from wolfberry and to investigate anti-inflammatory properties of these compounds using in vitro model. With optimized LC-MS/MS and NMR analysis, nine amide compounds were identified from the fruits. Seven of these compounds were identified in this plant for the first time. The amide compounds with a tyramine moiety were the most abundant. In vitro studies indicated that five HCCA compounds showed inhibitory effect on NO production inuded by lipopolysaccharides with IC50 less than 15.08 μM (trans-N-feruloyl dopamine). These findings suggested that wolfberries demonstrated anti-inflammatory properties.

The biomimetic synthesis of a small library of dihydrobenzofuran neolignanamides (the natural trans-grossamide (4) and the related compounds 21-28) has been carried out through an eco-friendly oxidative coupling reaction mediated by Trametes versicolor laccase. These products, after complete spectroscopic characterization, were evaluated for their antiproliferative activity against Caco-2 (colon carcinoma), MCF-7 (mammary adenocarcinoma), and PC-3 (prostate cancer) human cells, using an MTT bioassay. The racemic neolignamides (±)-21 and (±)-27, in being the most lipophilic in the series, were potently active, with GI50 values comparable to or even lower than that of the positive control 5-FU. The racemates were resolved through chiral HPLC, and the pure enantiomers were subjected to ECD measurements to establish their absolute configurations at C-2 and C-3. All enantiomers showed potent antiproliferative activity, with, in particular, a GI50 value of 1.1 μM obtained for (2R,3R)-21. The effect of (±)-21 on the Caco-2 cell cycle was evaluated by flow cytometry, and it was demonstrated that (±)-21 exerts its antiproliferative activity by inducing cell cycle arrest and apoptosis.
