- Discovery of a novel class of inhaled dual pharmacology muscarinic antagonist and β2 agonist (MABA) for the treatment of chronic obstructive pulmonary disease (COPD)
-
The targeting of both the muscarinic and β-adrenergic pathways is a well validated therapeutic approach for the treatment of chronic obstructive pulmonary disease (COPD). In this communication we report our effort to incorporate two pharmacologies into a single chemical entity, whose characteristic must be suitable for a once daily inhaled administration. Contextually, we aimed at a locally acting therapy with limited systemic absorption to minimize side effects. Our lung-tailored design of bifunctional compounds that combine the muscarinic and β-adrenergic pharmacologies by the elaboration of the muscarinic inhibitor 7, successfully led to the potent, pharmacologically balanced muscarinic antagonist and β2 agonist (MABA) 13.

- Scalable ruthenium-catalyzed asymmetric synthesis of a key intermediate for the β2-adrenergic receptor agonist
-
An enantioselective and robust synthetic process to obtain a useful intermediate for the β2-adrenergic receptor agonist is described. Asymmetric transfer hydrogenation of ketone 1c by (S,S)-3b (Ms-DENEB) afforded chiral alcohol 2c in 71% isolated yield and 99% ee. The deprotection completed the synthesis of (R)-5 in 41% overall yield from 1b, which is readily commercially available.
