磷酸异丙酯(单双酯混合物) 用途与合成方法
Uptake of hydroxycinnamic acids by control, organic anion transporter 1 (OAT1), OAT2, OAT3, and OAT4 over expressing 293H cells. In 293H control cells, there was significant uptake of Dihydroferulic acid. The uptake of Dihydroferulic acid is also enhanced ~2-fold in the OAT1-expressing cells.
Assessing the influence of an 11 weeks intervention with a resistant starch-enriched whole grain diet (HI-RS-WG, 25% RS) compared to a WG control diet (LOW-RS-WG, 6.9% RS) on serum profile of polyphenols (PPs) in 20 Zucker Diabetic Fatty rats. Five PPs were identified and quantified in serum samples of rats belonging to both intervention groups. HI-RS-WG rats had 2.6 folds higher serum concentrations of total PPs than LOW-RS-WG rats. An explorative data reduction approach, based on the Principal Component Analysis identified two principal components related to the gut microbiota fermentation and food intake, respectively. Results showed that the abundance of hippuric acid and Dihydroferulic acid in HI-RS-WG rats was explained by the stronger gut microbiota fermentation in those rats than in LOW-RS-WG rats.

以3-甲氧基-4-羟基苯基丙烯酸为原料合成磷酸异丙酯(单双酯混合物)的一般步骤如下：向搅拌的阿魏酸（25g，128.74mmol）在甲醇（200ml）中的悬浮液中加入Pd/C催化剂（3.75g）。将反应混合物置于1.2MPa氢气压力下，在50℃条件下氢化4小时。反应完成后，将混合物冷却至室温，过滤去除催化剂，并通过减压浓缩得到白色固体产物（25g，收率99%）。产物的结构通过1H NMR（400MHz，CDCl3）和ESI-MS进行确认：1H NMR δ 6.76（d, J = 7.8Hz, 1H），6.62（m, 2H），3.79（s, 3H），2.81（t, J = 7.7Hz, 2H），2.58（t, J = 7.7Hz, 2H）；ESI-MS m/z: 195.1 [M-H]?。
