描述 | Adenosine (ADO) is an inhibitory neuromodulator that can increase nociceptive thresholds in response to noxious stimulation. Inhibitors of the ADO-metabolizing enzyme adenosine kinase (AK) may have therapeutic potential as analgesic and anti-inflammatory agents. ABT702 2HCl is a novel and potent non-nucleoside AK inhibitor with an IC50 value of 0.7 nM. It has oral activity in animal models of inflammation and pain. ABT702 was equipotent (IC50 = 1.5 ± 0.3 nM) in inhibiting native human AK (placenta), two human recombinant isoforms (AKlong and AKshort), and AK from monkey, dog, rat, and mouse brain. ABT702 is orally active and fully efficacious in reducing acute somatic nociception (ED50 = 8 μmol/kg i.p.; 65 μmol/kg p.o.) in the mouse hot-plate assay. ABT702 also dose dependently reduced nociception in the phenyl-p-quinone-induced abdominal constriction assay[1]. Significant regional hypometabolism was detected of ABT702 (3 mg/kg; intraperitoneal injection) treated rats, relative to vehicle-treated rats[2]. |
