UP202-56

UP202-56 is an adenosine analogue, which is an adenosinergic agonist. IC50 & Target:Adenosine Receptor^[1][2] In Vitro: The effects of oral administration of UP202-56, an adenosine analogue, are assessed on carrageenan-induced spinal c-Fos protein expression and peripheral oedema. Oral UP202-56 (10, 30 or 50 mg/kg) dose-dependently reduces the number of carrageenan-induced c-Fos like immunoreactivity (c-Fos-LI) neurons (r=0.931. P<0.0001), with the highest dose of UP202-56 producing 72±4% reduction of the total number of carrageenan-induced spinal c-Fos-LI neurons, and 12±3% and 33±6% of reduction of control carrageenan oedema at paw and ankle levels, respectively. UP202-56 dose-dependently reduces the spinal c-Fos protein expression in carrageenan model of inflammatory pain^[1]. UP202-56 is an adenosinergic agonist^[2].
