Description

ABT-702 dihydrochloride is a potent adenosine kinase (AK) inhibitor (IC₅₀=1.7 nM).

IC₅₀ & Target

IC50: 1.7 nM (Adenosine kinase, AK)^[1]

In Vitro

ABT-702 is an orally effective adenosine kinase inhibitor that has several orders of magnitude selectivity over other sites of adenosine (ADO) interaction (A₁, A_2A, A₃ receptors, ADO transporter, and ADO deaminase). ABT-702 is equipotent (IC₅₀=1.5±0.3 nM) in inhibiting native human AK (placenta), two human recombinant isoforms (AK_long and AK_short), and AK from monkey, dog, rat, and mouse brain. ABT-702 potently inhibits the activity of rat brain cytosolic AK in a concentration-dependent manner with an IC₅₀ value of 1.7 nM. ABT-702 also potently inhibits AK activity in intact cultured IMR-32 human neuroblastoma cells (IC₅₀=51 nM), indicating that ABT-702 can penetrate the cell membrane and potently inhibit AK at its intracellular site^[1].

In Vivo

ABT-702 significantly reduces acute thermal nociception in a dose-dependent manner after both intraperitoneal (ED₅₀=8 μmol/kg i.p.) and oral (ED₅₀=65 μmol/kg p.o.) administration in the mouse hot-plate test. Consistent with its antinociceptive effects in the hot-plate assay, ABT-702 also produces dose-dependent antinociceptive effects (ED₅₀=2 μmol/kg i.p.) in the abdominal constriction assay. ABT-702 exhibits full efficacy in this model of persistent chemical pain^[1]. Rats are given an intraperitoneal injection of the adenosine A₁ receptor antagonist DPCPX (3 mg/kg), ABT-702 (3 mg/kg), or vehicle 10 minutes prior to an intravenous injection of 2-¹⁸F-fluorodeoxy-D-glucose (FDG) (FDG, 15.4±0.7 MBq per rat). Rats are then subjected to a 15 minute static positron emission tomography (PET) scan. Reconstructed images are normalized to FDG PET template for rats and standard uptake values (SUVs) are calculated. To examine the regional effect of active treatment compared to vehicle, statistical parametric mapping analysis is performed. Whole-brain FDG uptake is not affected by drug treatment. Significant regional hypometabolism is detected, particularly in cerebellum, of DPCPX and ABT-702 treated rats, relative to vehicle-treated rats. Thus, endogenous adenosine can affect FDG accumulation although this effect is modest in quiescent rats. Body weight (316.8±28.4 g; mean±SD) and blood glucose (5.5±1.7 mM) are not significantly different among three groups. Whole-brain PET SUV values are 1.6±0.4, 1.6±0.6, and 1.8±0.6 for vehicle, ABT-702, and DPCPX-treated rats, respectively (F(2,9)=0.298, P=0.75). statistical parametric mapping (SPM) analysis reveals significant regional hypometabolism in the cerebellum, mesencephalic region, and medulla in the ABT-702-treated rats compared to the vehicle-treated rats^[2].

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 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.66 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 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Animal Administration
^[2]

Rats^[2]
Rats are fasted for 16 hours prior to use. At the beginning of the experiment, each rat is weighed, and then anesthetized using 5% isoflurane for induction and 2.5% for maintenance. A blood sample from tail vein is collected for a fasting blood glucose determination using a standard glucometer. Rats are then given an intraperitoneal (i.p.) injection of DPCPX (3 mg/kg, n=4), ABT-702 (3 mg/kg, n=4), or an equivalent volume of vehicle (15% dimethyl sulfoxide, 15% cremophor EL, 70% saline, n=4) to manipulate the effect of endogenous adenosine on neuronal activities. Ten minutes after i.p. injection, rats are administered FDG (15.4±0.7 MBq) in 0.3-0.5 mL saline by intravenous (i.v.) tail vein injection. Rats are allowed to recover from anesthesia after the FDG injection but are reanesthetized for 15-minute-static PET scan with the head in the center of the field of view. All images are reconstructed^[2].
