AB-MECA is an adenosine A3 receptor agonist (Ki = 430.5 nM for the human receptor expressed in CHO cells).{45426} It inhibits LPS-induced TNF-? production in primary cultured human lung macrophages (pD2 = 6.9).{45427} AB-MECA increases contraction of isolated guinea pig trachea ex vivo when used at a concentration of 0.1 ?M and increases bronchoconstriction in vivo when administered at a dose of 3 ?g/kg in a guinea pig model of ovalbumin-sensitized asthma.{45428} A radiolabeled form of AB-MECA has been used for radioligand binding assays and binds to rat adenosine A1 and A3 receptors (Kds = 3.42 and 1.48 nM in COS-7 and CHO cells, respectively) and canine adenosine A2a receptors (Kd = 25.1 nM in COS-7 cells).{45429}
