Biochem/physiol Actions

内源性 H1 和 H2 组胺受体激动剂;可活化一氧化氮合成酶;有效的血管舒张剂。
组胺二盐酸盐已被证明可激活一氧化氮合成酶并抑制活性氧(ROS)的产生。组胺二盐酸盐对ROS的抑制使得IL-2可以激活T细胞和NK细胞。在大鼠模型中,组胺二盐酸盐通过H2组胺受体抑制由Kupffer细胞产生的ROS

General description

组胺是通过L-组氨酸脱羧酶使组氨酸发生脱羧而衍生出的一种亲水性胺。组胺已在多种生理过程中显示出作用,如胃分泌、神经传递、免疫反应、血管舒张和炎症。 此外,已有研究报道了组胺二盐酸盐与白介素2(IL-2)在治疗急性髓细胞性白血病和预防酒精引起的大鼠肝损伤中的作用

Other Notes

用于组胺-N-甲基转移酶(EC 2.1.1.8)检测的底物;离子对提取生物体液中的组胺并通过HPLC—荧光检测法定量
