一般描述
据报道，3,4-二羟基苯甲酸是一种食品多酚。在小鼠模型中，3,4-二羟基苯甲酸（原儿茶酸，PCA）对毒性H9N2病毒株的抗病毒活性已有报道。PCA对3种非小细胞肺癌（NSCLC）细胞系（A549、H3255和Calu-6细胞系）的细胞毒性作用已有报道。据报道，PCA可在体内预防癌变或抗肿瘤生长。PCA诱导的人胃腺癌（AGS）细胞凋亡的相关信号通路已有报道。水/针铁矿料浆中的H2O2在不同操作条件（催化剂负载、温度、酸碱度、底物和过氧化氢起始浓度）下，对3，4-二羟苯甲酸的氧化作用已有研究。
应用
3,4-二羟基苯甲酸适用于在体内研究4-香豆酸和3,4-二羟基苯甲酸对大鼠结肠黏膜基础氧化性DNA损伤的影响。它可用于壳聚糖树脂的衍生化。
生化/生理作用
几个致癌作用的动物模型中的化学防癌剂。在后启动阶段阻断细胞增殖。

The oxidation by H2O2 of 3,4-dihydroxybenzoic acid (3,4-DHB) in aqueous/goethite slurry at varying operating conditions (catalyst load, temperature, pH, substrate and hydrogen peroxide starting concentration) is investigated. At adopted catalyst loads the observed kinetic developments are consistent with a non-radicalic
