Product Introduction
Bioactivity


英文名: Dabigatran Etexilate Mesylate

描述: Dabigatran Etexilate Mesylate (BIBR 1048MS) 是一种口服具有活性的 Dabigatran 前药，具有抗凝作用，能够预防心房颤动引起的静脉血栓栓塞和中风。

体外活性: Dabigatran selectively and reversibly inhibited human thrombin(Ki: 4.5 nM) as well as thrombin-induced platelet aggregation (IC50: 10 nM), while showing no inhibitory effect on other platelet-stimulating agents. Thrombin generation in platelet-poor plasma (PPP), measured as the endogenous thrombin potential (ETP) was inhibited concentration-dependently (IC50: 0.56 μM). Dabigatran demonstrated concentration-dependent anticoagulant effects in various species in vitro, doubling the activated partial thromboplastin time (aPTT), prothrombin time (PT) and ecarin clotting time (ECT) in human PPP at concentrations of 0.23, 0.83 and 0.18 μM, respectively [1].

体内活性: Dabigatran prolonged the aPTT dose-dependently after intravenous administration in rats (0.3, 1 and 3 mg/kg) and rhesus monkeys (0.15, 0.3 and 0.6 mg/kg). Dose- and time-dependent anticoagulant effects were observed with dabigatran etexilate administered orally to conscious rats (10, 20 and 50 mg/kg) or rhesus monkeys (1, 2.5 or 5 mg/kg), with maximum effects observed between 30 and 120 min after administration, respectively [1]. Patients treated with dabigatran etexilate experienced fewer ischaemic strokes (3.74 dabigatran etexilate vs 3.97 warfarin) and fewer combined intracranial hemorrhages and hemorrhagic strokes (0.43 dabigatran etexilate vs 0.99 warfarin) per 100 patient-years [2].

存储条件: Powder: -20°C for 3 years | In solvent: -80°C for 1 year
