Background

AB-MECA is an adenosine A₃ receptor agonist (K_i = 430.5 nM for the human receptor expressed in CHO cells).¹ It inhibits LPS-induced TNF-α production in primary cultured human lung macrophages (pD₂ = 6.9).² AB-MECA increases contraction of isolated guinea pig trachea ex vivo when used at a concentration of 0.1 μM and increases bronchoconstriction in vivo when administered at a dose of 3 μg/kg in a guinea pig model of ovalbumin-sensitized asthma.³ A radiolabeled form of AB-MECA has been used for radioligand binding assays and binds to rat adenosine A₁ and A₃ receptors (K_ds = 3.42 and 1.48 nM in COS-7 and CHO cells, respectively) and canine adenosine A_2a receptors (K_d = 25.1 nM in COS-7 cells).⁴
