Navafenterol
Navafenterol (AZD-8871) is an inhaled dual-acting, potent, selective, and long-lasting M3-antagonist/β2-agonist (MABA) with long-lasting effects and favorable safety profile. The pIC50 is 9.5 for human M3 receptor, and the pEC50 is 9.5 for β2-adrenoceptor. Navafenterol can be used for the research of chronic obstructive pulmonary disease (COPD). Bronchoprotective and antisialagogue effects. Favorable cardiovascular profile.

mAChR3 |
The pIC50 values of Navafenterol (AZD-8871) at the human M1, M2, M3, M4, and M5 receptor are 9.9, 9.9, 9.5, 10.4, and 8.8, respectively[1].
pEC50 values of Navafenterol at theβ1, β2, and β3 adrenoceptor are 9.0, 9.5, and 8.7, respectively. It is selective for the β2-adrenoceptor over the β1 and β3 subtypes (3- and 6-fold, respectively)[1].
Navafenterol shows kinetic selectivity for the M3 (half-life: 4.97 hours) over the M2 receptor (half-life: 0.46 hour)[1].
Navafenterol 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, respectively), which are sustained over time[1].
