概述
3-甲氧基-4-羥基扁桃酸是制備新型廣譜抗菌藥物甲氧芐胺嘧啶和香草醛的重要中間體，3-乙氧基-4羥基扁桃酸是制備乙氧基香草醛的中間體。香蘭素或乙基香蘭素為廣譜香料，可用作定香劑、調味劑和變味劑。用途
3-甲氧基-4-羥基扁桃酸是制備新型廣譜抗菌藥物甲氧芐胺嘧啶和香草醛的重要中間體。生物活性
Vanillylmandelic acid (VMA)是合成人工香草調味料的中間物，是兒茶酚胺的終末期代謝物。體外研究
Vanillylmandelic acid has antioxidant activity, the IC 50 value is determined as the amount of VMA required to reduce 50% of the starting concentration of free radical is 33*10 -6 M in the UV-Vis decolourisation DPPH assay.
體內研究
Vanillylmandelic acid (intra-arterial injection over 1 min; 1, 10 and 100 mg/kg; the 60 min-observation period) produces a significant difference between vanillylmandelic acid groups and controls. Vanillylmandelic acid decreases the heart rate by 17.5%, 17.9% and 18.9% after 1, 10 and 100 mg/kg, respectively. Mean blood pressure is decreased by 13.5% in control animals as compared to 37%, 23% and 26% after 1, 10 and 100 mg/kg, respectively, in wistar rats.
