From: Pharmacological characterisation of novel adenosine A3 receptor antagonists

Characterisation of A3R antagonist at all AR subtypes. A3R Flp-In CHO cells or CHO-K1 cells (2000 cells/well) stably expressing one of the remaining AR subtypes were exposed to forskolin in the case of Gi-coupled A1R and A3R (1 μM or 10 μM, respectively) or DMSO control in the case of Gs-coupled A2AR and A2BR, NECA and test compound (10 μM) for 30 min and cAMP accumulation detected. All values are mean ± SEM expressed as percentage forskolin inhibition (A1R and A3R) or stimulation (A2AR and A2BR), relative to NECA. n ≥ 3 independent experimental repeats, conducted in duplicate.
