Design-driven LO: The discovery of new ultra long acting dibasic β2-adrenoceptor agonists

Starting with the molecular scaffold of the DA2/β2 dual agonist sibenadet (Viozan™), a number of molecular changes were incorporated, which were designed to increase the potency and selectivity of the target molecule, and improve its pharmacokinetics. Through this process a novel, high potency, full β2-agonist with high selectivity and long duration capable of being dosed once daily has been discovered.
