AZD8871 is a novel muscarinic antagonist and β2-adrenoceptor agonist in development for chronic obstructive pulmonary disease. This study describes the pharmacological profile of AZD8871 in in vitro and in vivo assays. AZD8871 is potent at the human M3 receptor (pIC50 in binding assays: 9.5) and shows kinetic selectivity for the M3 (half-life: 4.97 hours) over the M2 receptor (half-life: 0.46 hour). It is selective for the β2-adrenoceptor over the β1 and β3 subtypes (3- and 6-fold, respectively) and shows dual antimuscarinic and β2-adrenoceptor functional activity in isolated guinea pig tissue (pIC50 in electrically stimulated trachea: 8.6; pEC50 in spontaneous tone isolated trachea: 8.8, r…
Pharmacological preclinical characterization of LAS190792, a novel inhaled bifunctional muscarinic receptor antagonist /β 2 -adrenoceptor agonist (MA…

LAS190792 is a novel muscarinic antagonist and β2-adrenoceptor agonist in development for chronic respiratory diseases. This study investigated the pharmacological profile of LAS190792 in comparison to batefenterol, tiotropium, indacaterol and olodaterol. LAS190792 is potent at the human M3 receptor (pIC50: 8.8 in binding assays). It is selective for the β2-adrenoceptor over the β1-and β3-adrenoceptor, and shows a functional potency in a similar range to batefenterol and LABA compounds (pEC50 in spontaneous tone isolated trachea: 9.6). The relaxant potency of LAS190792 in electrically stimulated tissue is similar to batefenterol, with an antimuscarinic activity in presence of propranolol sl…
