Description

Apixaban (BMS-562247-01) is a highly selective, reversible and orally active inhibitor of Factor Xa with Ki of 0.08 nM and 0.17 nM in human and rabbit, respectively[1]. Apixaban is in development for the prevention and treatment of various thromboembolic diseases[2].

IC50 & Target

IC50: 0.08 nM (Human Factor Xa), 0.17 nM (Rabbit Factor Xa)

In Vitro

Apixaban (BMS-562247-01) prolongs the clotting times of normal human plasma with the concentrations (EC2x) of 3.6 μM, 0.37 μM, 7.4 μM, and 0.4 μM, which are required respectively to double the prothrombin time (PT), modified prothrombin time (mPT), activated partial thromboplastin time (APTT) and HepTest. Besides, Apixaban shows the highest potency in human and rabbit plasma, but less potency in rat and dog plasma in both the PT and APTT assays[2].

In Vivo

Apixaban (BMS-562247-01) shows the excellent pharmacokinetics with very low clearance (Cl: 0.02 L/kg/h), and low volume of distribution (Vdss: 0.2 L/kg) in the dogs. Besides, Apixaban also exhibits a moderate half-life (T1/2: 5.8 hours) and good oral bioavailability (F: 58%)[1].
? In the arteriovenous-shunt thrombosis (AVST), venous thrombosis (VT) and electrically mediated carotid arterial thrombosis (ECAT) rabbit models, Apixaban produces dose-dependent antithrombotic effects with EC50 of 270 nM, 110 nM and 70 nM, respectively[2].
? Apixaban significantly inhibits factor Xa activity with IC50 of 0.22 μM in rabbit ex vivo[3].
? In chimpanzee, Apixaban also shows small volume of distribution (Vdss: 0.17 L/kg), low systemic clearance (Cl: 0.018 L/kg/h), and good oral bioavailability (F: 59%)[4].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

  • Protocol 1

    Add each solvent one by one:  10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (5.44 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

    Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
  • Protocol 2

    Add each solvent one by one:  10% DMSO    90% Corn Oil

    Solubility: ≥ 2.5 mg/mL (5.44 mM); Clear solution

    This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.

    Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Kinase Assay
[2]

Purified FXa is obtained after activation with Russell’s viper venom followed by affinity chromatography. The resulting FXa is > 95% pure as judged by sodium dodecylsulfate polyacrylamide gel electrophoresis. The substrate affinity values for FXa, expressed as the Michaelis-Menten-Henri constant (Km), for human, rabbit, rat and dog FXa are determined using the chromogenic substrate S-2765, and are 36, 60, 240 and 70 μM, respectively. The substrate hydrolysis is monitored by measuring absorbance at 405 nm at 25°C for up to 30 min using a SpectraMax 384 Plus plate reader and SoftMax. FXa activity for each substrate and inhibitor concentration pair is determined in duplicate. The Ki values are calculated by non-linear least-squares fitting of the steady-state substrate hydrolysis rates to the equation for competitive inhibition (Equation 1) using GRAFIT, where v equals reactions velocity in OD min−1, Vmax equals maxiumum reaction velocity, S equals substrate concentration, and I equals inhibitor concentration.

Animal Administration
[2]

Briefly, male New Zealand White rabbits are anesthetized with ketamine (50 mg/kg i.m.) and xylazine (10 mg/kg i.m.), and their femoral artery, jugular vein and femoral vein are catheterized. Thrombosis is induced by an arteriovenous (AV)-shunt device containing a silk thread. Blood flowed from the femoral artery via the AV shunt into the opposite femoral vein for 40 min. The shunt is then disconnected and the silk thread covered with thrombus is weighed. As apixaban has an oral bioavailability of < 5% in rabbits (unpublished result), it is administered intravenously for in vivo studies. To achieve a stable plasma level with minimum experimental variability, apixaban, fondaparinux or vehicle is given by a continuous intravenous infusion 1 h prior to shunt placement. The infusion is continued throughout the experiment. Warfarin or vehicle is dosed orally once daily for 4 days. On the fourth day after the last oral dose of warfarin or vehicle, rabbits are anesthetized 1.5 h later, and the treatment effect is evaluated about 2 h postdose. Arterial blood samples for the determination of clotting times or plasma levels are collected 20 min after shunt placement. Plasma levels of apixaban are measured by a specific and sensitive liquid chromatographic mass spectrometry method (LC/MS/MS). In rabbits treated with apixaban, fondaparinux or warfarin, the antithrombotic effects of these agents are expressed as percentage inhibition of thrombus formation based on the treated vs. the corresponding mean vehicle. The ED50 value (dose that produced 50% inhibition of thrombus formation) is determined as described below. The apixaban group treatment consists of vehicle (10%N,N-dimethylacetamide; 30% 1,2-propanediol; 60% water) (n=4), and apixaban (mg/kg/h) at 0.03 (n=7), 0.1 (n=7), 0.3 (n=7), 1 (n=7), and 3 (n=3). The fondaparinux group treatment consists of vehicle (saline) (n=6), and fondaparinux (mg/kg/h1) at 0.01 (n=5), 0.03 (n=5), 0.1 (n=5), 0.3 (n=5), and 1 (n=5). The warfarin group treatment consists of vehicle (water) (n=6), and warfarin (mg/kg/day) at 0.1 (n=6), 0.3 (n=6), 1 (n=6), and 3 (n=6).

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
