Clopidogrel hydrogen sulfate is an orally effective purine-type P2Y12 receptor antagonist. The IC50 values for cytochrome P450 (CYP) subtypes CYP2B6 and CYP2C19 are 18.2nM and 524nM, respectively [1-2]. The P2Y12 receptor combines with the Gq pathway and promotes the release of intracellular calcium ions, thereby regulating the shape changes and aggregation process of platelets [3]. Clopidogrel hydrogen sulfate is a potent antithrombotic drug that can inhibit platelet aggregation triggered by adenosine diphosphate (ADP) [4].
In vitro, Clopidogrel hydrogen sulfate (0.5, 1.5mM; 24, 48h) upregulated the mRNA expression levels of TRIB3 and CHOP in GES-1 cells in a concentration- and time-dependent manner [5]. Clopidogrel hydrogen sulfate (1, 10 and 100μM; 24h) treatment concentration-dependently increased the cytotoxicity and intracellular ROS levels of HepG2 cells (expressing human CYP3A4) [6].
In the body, Clopidogrel hydrogen sulfate (1.25, 2.5, 3.75 and 5mg/kg; twice; gavage) can significantly inhibit thrombosis formation in a dose-dependent manner in the mouse arterial thrombosis model. When combined with acetylsalicylic acid (0.15mg/kg), it can enhance the antithrombotic effect of Clopidogrel hydrogen sulfate, while acetylsalicylic acid (0.6mg/kg) can weaken its antithrombotic effect [7]. 24 hours before the ischemia-reperfusion surgery, oral administration of Clopidogrel hydrogen sulfate (25mg/kg/day) significantly reduced the plasma levels of blood urea nitrogen (BUN) and creatinine in mice with renal ischemia-reperfusion injury (IRI), increased the expression of Bcl-2 and Bcl-xL, caspase-3 and caspase-8, and decreased the number of CD41-positive cells [8].

Clopidogrel hydrogen sulfate是一种口服有效的嘌呤能P2Y12受体拮抗剂，对细胞色素P450（CYP）亚型CYP2B6和CYP2C19的IC50值分别为18.2nM和524nM [1-2]。P2Y12受体与Gq通路相结合，并促使细胞内钙离子释放，从而调节血小板的形状变化和聚集过程 [3]。Clopidogrel hydrogen sulfate是一种强效的抗血栓药物，能够抑制二磷酸腺苷（ADP）引发的血小板聚集 [4]。
在体外，Clopidogrel hydrogen sulfate（0.5, 1.5mM; 24, 48h）以浓度和时间依赖性方式上调了GES-1细胞中TRIB3和CHOP的mRNA表达水平 [5]。Clopidogrel hydrogen sulfate（1, 10和100μM; 24h）处理浓度依赖性地增加了对HepG2细胞（表达人类CYP3A4）的细胞毒性和细胞内ROS的水平 [6]。
在体内，Clopidogrel hydrogen sulfate（1.25, 2.5, 3.75和5mg/kg; 共两次; 灌胃）能够以剂量依赖性方式显著抑制小鼠动脉血栓形成模型中血栓的形成。与乙酰水杨酸（0.15mg/kg）合用可以增加Clopidogrel hydrogen sulfate的抗血栓形成作用，而乙酰水杨酸（0.6mg/kg）会减弱其抗血栓形成作用 [7]。在缺血再灌注手术前24小时通过口服Clopidogrel hydrogen sulfate（25mg/kg/day）显著降低了肾缺血再灌注损伤（IRI）小鼠血尿素氮（BUN）和肌酐的血浆水平，增加了Bcl-2和Bcl-xL、caspase-3和caspase-8表达降低，并减少了CD41阳性细胞的数量 [8]。
| Cell experiment [1]: | |
Cell lines | GES-1 cells |
Preparation Method | GES-1 cells were plated in 60-mm dishes (3ml, 1×106/well) and incubated for 24h at 37°C. After 24-h treatment with Clopidogrel hydrogen sulfate, the cells were collected and washed twice with ice-cold PBS, and then were re-suspended in binding buffer at a concentration of 1×106 cells/ml and incubated with 10µl of PI (50µg/ml) solution and 5µl of FITC-conjugated AV (17.6µg/ml) at 37°C for 5min in the dark to achieve double staining. After staining, 400µl of binding buffer were added to the cells, and then analyzed by flow cytometry. |
Reaction Conditions | 1.5mM; 24h |
Applications | Clopidogrel hydrogen sulfate significantly inhibits the proliferation of GES-1 cells and induces apoptosis. |
| Animal experiment [2]: | |
Animal models | C57BL/6J mice |
Preparation Method | Clopidogrel hydrogen sulfate were dissolved in diluted apple jelly and acetylsalicylic acid (ASA) were dissolved in distilled water. Age-matched C57BL/6J male mice weighing at least 25g were used at 8 to 12 weeks of age. Anesthesia was initiated with an intraperitoneal injection of 125mg/kg of ketamine, 12.5mg/kg of xylazine, and 0.25mg/kg of atropine and maintained with Nembutal. All mice received 100μL of vehicle or an equal volume of ASA, Clopidogrel hydrogen sulfate or both by gavage using 20-gauge animal feeding needles. ASA was given only once, 4 hours before study, whereas clopidogrel was given twice: 24 and 4 hours before study. ASA and clopidogrel were given at doses up to 5mg/kg body weight. Blood samples were collected via carotid artery cannulation into 3.2% sodium citrate at a ratio of 9:1 (vol:vol). Blood was diluted and recalcified with 1.5mM CaCl2, and platelet aggregation, quantified by area under the curve (AUC), in whole blood was recorded for 6min after using a Multiplate Analyzer. |
Dosage form | 1.25, 2.5, 3.75, or 5mg/kg; twice; gavage |
Applications | Clopidogrel hydrogen sulfate can significantly inhibit thrombosis formation in a dose-dependent manner in a mouse model of arterial thrombosis. When used in combination with acetylsalicylic acid (0.15mg/kg), it can enhance the antithrombotic effect of Clopidogrel hydrogen sulfate, while acetylsalicylic acid (0.6mg/kg) will weaken its antithrombotic effect. |
