应用


  • Metabolic Fate Characterization: Sinapic acid′s metabolic fate in biological systems is a significant area of research. Recent studies in rats have focused on identifying the metabolic pathways and by-products of sinapic acid, using advanced techniques such as liquid chromatography-mass spectrometry (LC-MS). These studies provide insights into its bioavailability and pharmacokinetics, which are crucial for understanding its therapeutic potential (Analytical and Bioanalytical Chemistry, 2023).

  • Efficient Extraction from Plant Materials: Sinapic acid is extracted from various plant sources using molecularly imprinted polymers (MIPs) and deep eutectic solvents. These methods enhance the efficiency and selectivity of sinapic acid extraction, making it a valuable approach for analytical chemists working on natural product isolation and characterization. This application is particularly relevant in the food and pharmaceutical industries for quality control and standardization (Food Chemistry, 2023).

  • Selective Sensing Applications: Sinapic acid is used in the development of nanocomposites for selective sensing applications. For instance, Ni-sinapic acid nanocomposites have been developed for the selective detection of permanganate ions. This research showcases the versatility of sinapic acid in creating sensitive and specific sensors for environmental monitoring and analytical applications (Journal of Photochemistry and Photobiology A: Chemistry, 2023).

  • Bioactivity Studies: The bioactivity of sinapic acid extends to its anti-inflammatory and anticancer properties. Studies have shown that sinapic acid can modulate various biochemical pathways, providing protective effects against inflammation and cancer. These findings underscore its potential as a bioactive compound in therapeutic formulations and highlight the importance of analytical methods in quantifying its efficacy and safety (Stem Cell Research International, 2022).

生化/生理作用

芥子酸适合作为高效液相色谱测定油菜籽提取物中芥子酸衍生物的酚性标准品, 10 g/L 的芥子酸溶剂溶液适合作为紫外激光解吸质谱法测定蛋白质的基质。也适用于作为 MALDI-TOFMS 和 MALDI-离子迁移-TOFMS 的基质,以测定组织中的磷脂。
苯丙氨酸解氨酶催化苯丙氨酸脱氨基生成肉桂酸。羟基肉桂酸的前体是苯环羟基化后生成的。生成的前体之一是芥子酸。芥子酸具有抗菌、抗氧化、抗癌、抗炎和抗焦虑活性。芥子碱是一种乙酰胆碱酯酶抑制剂,在临床上广泛应用于多种疾病的治疗。4-乙烯基丁香醇(芥子酸的脱羧产物)是一种强效抗突变和抗氧化剂,参与抑制炎性细胞因子的诱导和致癌作用。由于具有抗氧化活性,这些化合物被认为可能用于制药工业、化妆品和食品加工。
