[ 靶点 ]

Kd: 0.8 nM (Histamine H1 receptor), 5200 nM (Histamine H2 receptor), >3000 nM (Histamine H3 receptor)[1] pKd: 9.4 (Histamine H1 receptor)[2]

[体外研究]

马来酸美吡拉敏是组胺H1受体的拮抗剂,H1,H2和H3受体的Kds分别为0.8 nM,5200 nM和> 3000 nM [1],H1受体的pKd为9.4 [2]。美吡拉敏与豚鼠脑(0.8 nM),大鼠脑(9.1 nM)和DDT1-MF-2和BC3H1细胞(276 nM)中不同Kds的H1受体结合[1]。美吡拉敏降低CHO-gpH1细胞中的InsP水平,log EC50为-7.94±0.11,并降低CHO-gpH1细胞对ATP的最大反应[3]。

[体内研究]

美吡拉敏通过腹腔注射10和20 mg/kg明显降低伤害性反应的第二阶段,但对大鼠5 mg/kg无显着影响[4]。

[细胞实验]

简而言之，将细胞接种在24孔簇培养皿中并在DMEM中培养24小时（70-80％汇合）。然后洗涤细胞，并将培养基更换为不含小牛血清的DMEM加上myo- [3H]肌醇（2μCi/ mL）并培养24小时。此后，吸出培养基并用不含有10mM LiCl的小牛血清的DMEM替换，并孵育20分钟。然后在存在或不存在[3H]肌醇的情况下，在每个特定实验中指示的浓度下，用浓度范围为1nM至100μM的最终体积300μL的组胺刺激细胞20分钟。通过加入900μL冷氯仿，甲醇，0.12M HCl（1：2：1v / v，新制备）来终止温育，并通过添加300μL水和300μL氯仿来分离各相。。然后将混合物以1500×g离心10分钟，并通过阴离子交换色谱法纯化总的水溶性肌醇磷酸酯级分。使用液体闪烁计数器测量洗脱级分的放射性。结果表示为当总[3H]肌醇磷酸盐放射性标准化为从柱的初始水洗中回收的总[3H]肌醇放射性时获得的比例[3]。

[动物实验]

大鼠[4]将体重为200-220g的健康成年雄性白化Wistar大鼠保持在聚丙烯笼中，每个笼中有6只大鼠，随意提供食物和水。美吡拉敏溶于正常的saine。剂量为5,10和20mg / kg的美吡拉敏，并在诱导伤害感受前30分钟腹膜内注射。在诱导福尔马林诱导的疼痛之前20和40分钟分别皮下施用剂量为0.05,0.1和0.2mg / kg的毒扁豆碱和剂量为2mg / kg的阿托品。在皮下注射毒扁豆碱（0.1mg / kg）之前20分钟注射阿托品（2mg / kg，sc）。在联合治疗中，在毒扁豆碱（0.1mg / kg，sc）给药前10分钟和阿托品（0.2mg / kg，sc）给药后10分钟腹膜内注射美吡拉敏（10mg / kg）和法莫替丁（20mg / kg）。。使用25号注射针以1mL / kg的体积腹膜内注射药物溶液。使用27号注射针在颈部区域以每只大鼠0.2mL的体积注射药物溶液进行皮下注射[4]。
