一般說明

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

生化/生理作用

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

其他說明

用于组胺-N-甲基转移酶(EC 2.1.1.8)检测的底物;生物体液中组胺的离子对提取用于通过带有荧光检测的HPLC对其进行测定

To test whether recombinant human diamine oxidase (rhDAO) with a mutated heparin-binding motif (mHBM), which shows an increased alpha-distribution half-life, prevents histamine-induced hemodynamic effects. Thirty-eight female guinea pigs were either pretreated with rhDOA_mHBM or buffer. Guinea pigs received a continuous
