一般說明
组胺是由下丘脑后部神经元产生的神经递质。大脑中,组胺主要存在于灰质部分。
應用
组胺用于:
- 刺激调节型细胞分泌
- 在反应混合物中,活化血液,通过荧光测定法测定凝血酶(因子iia)活性
- 填充腔室腔侧,研究其对TJ相关屏障的影响以及声带上皮中TJ(紧密连接)标志物的表达
生化/生理作用
内源性 H1 和 H2 组胺受体激动剂;H1 的活化可以使 Ca2+ 移动;H2 的活化可促进神经元中腺苷酸环化酶的活性;活化一氧化氮合成酶;有效的血管舒张剂。
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。
组胺参与先天免疫应答和获得性免疫应答,介导过敏和炎症。有助于肠道肌肉收缩。在过敏性休克过程中,组胺引起支气管收缩。组胺还参与分泌胃酸、控制上皮和内皮屏障。

Using a previously reported flexible alignment model we have designed, synthesized, and evaluated a series of compounds at the human histamine H 4 receptor (H 4R) from which 2-(4-methyl-piperazin-1-yl)-quinoxaline ( 3) was identified as a new lead structure for H

The histamine H(3) (H(3)R) and H(4) (H(4)R) receptors attract considerable interest from the medicinal chemistry community. Given their relatively high homology yet widely differing therapeutic promises, ligand selectivity for the two receptors is crucial. We interrogated H(4)R/H(3)R selectivities using ligands
