一般描述
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Propyl gallate is a synthetic phenolic antioxidant (SPA) utilized in food additives to inhibit or regulate the lipid oxidation. SPAs are cost-effective, largely available and highly efficient in comparison to their natural counterparts.
应用
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Propyl gallate may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and fatty liquids by chromatography and spectrophotometry.
在荧光显微术中用作抗淬灭剂，以减少罗丹明和荧光素等荧光探针的光漂白。
生化/生理作用
表现出抗菌活性的抗氧化剂。据报道，五倍子酸丙酯是一种有效的、抗氧化剂类体内外护肝剂。另据证明，它能防止神经元凋亡，阻止暴露于 FeSO4/GA 的神经元死亡，以及在一定程度上防止 TNF-诱导的内皮细胞凋亡。但是，当五倍子酸丙酯浓度高于 0.25μM，同时存在 5μM 及更高浓度的铜时，会诱导 DNA 单链断裂。另有报道称，使用浓度 >1mM 的五倍子酸丙酯进行离体大鼠肝细胞培养会诱导细胞死亡，而 >0.5mM 的较低浓度的五倍子酸丙酯导致了可溶性低分子量 DNA 片段的 ladder 形成，这是细胞凋亡的特征。
