General description
水杨酸主要用作合成阿司匹林的前体,阿司匹林是一种常用的镇痛药和解热药。由于其角质层分离作用,它也可用于局部软膏中。
Application
水杨酸已用于:
- 作为化合物之一对发育毒性筛选检测中使用的体外原肠胚形成模型进行暴露验证
- 作为反相高效液相色谱(RP-HPLC)法测定水杨酸盐含量的标准品。
Biochem/physiol Actions
水杨酸(SA)对植物的各种病害具有局部和全身获得性抗性(LAR和SAR)。它是一种次生代谢物,调节各种生理过程,如呼吸作用、气孔关闭和衰老相关基因表达。此外,SA还控制非生物胁迫、基础耐热性、豆类结瘤和水果产量。它在调节植物的开花和生热(产热)中起着至关重要的作用。SA与活性氧(ROS)和一氧化氮(NO)一起触发植物的细胞死亡。
