产品描述 |
一种口服有效的选择性的factor Xa (fXa)抑制剂。 |
|
靶点 |
Factor Xa 1.5nM |
|
体外研究 |
In patch clamp hERG assays, Betrixaban has IC50 of 8.9μM. The plasma kallikrein IC50 and Ki values for Betrixaban are 6.3μM and 3.5μM respectively. Betrixaban (hERG Ki 1.8μM) exhibits significantly lower hERG activity than all the others (hERG Ki 0.5μM) |
|
体内研究 |
Dosed at 0.5mg/kg IV and 2.5mg/kg PO, Betrixaban has bioavailability of 51.6% in dog; dosed at 0.75mg/kg IV and 7.5mg/kg PO, Betrixaban has bioavailability of 58.7% in monkey. Both Betrixaban and Apixa-ban-mediated whole-blood INR increases are similarly reversed by r-Antidote. After i.v. infusion of the three fXa inhibitors (each admin¬istered individually) for 30 min, the total plasma concentrations of rivaroxaban, Betrixaban and apixaban are 1.4±0.4μM (mean±s.d.), 0.2±0.01μM and 1.4±0.3μM, respectively, and the percentages of unbound inhibitor are 2.2%±0.8% (mean±s.d.), 40%±7.2% and 1.5%±0.3%, respectively. After administration of r-Antidote, the total plasma concentrations of the inhibitors increased to 1.9±0.09μM, 2.0±0.4μM and 4.2±0.7μM, respectively, and the percentage of unbound inhibitor declined to 0%, 0.3%±0.1% and 0.05%±0.02%, respectively. Thus, for each of the three inhibitors, correction of prothrombin time by r-Antidote to nearnormal values is associated with a reduction in the free fraction of the inhibitor |

Animal Administration |
Rats Whole-blood INR values (mean±s.d.) in rats infused with Betrixaban (1mg/kg per hour) or vehicle and then treated with either vehicle or r-Antidote by i.v. bolus (6mg) over 5 min plus infusion (9mg/h) for up to 90 min. Circles, vehicle+vehicle; squares, Betrixaban + vehicle; triangles, Betrixaban + r-Antidote. *P≤0.02 compared to the r-Antidote treatment group determined by unpaired two-tailed t test. Whole-blood INR values (mean±s.d.) in rats infused with Apixaban (0.5mg per kg body weight h−1) or vehicle and then treated with either vehicle or r-Antidote by i.v. bolus (6mg) over 5 min plus infusion (6mg/h) for up to 90 min. Circles, vehicle + vehicle; squares, apixaban + vehicle; triangles, apixaban+r-Antidote. *P≤0.01 compared to the r-Antidote treatment group determined by unpaired two-tailed t test. |

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL Saline/PBS/ddH2O,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
