Inhalation by design: dual pharmacology ß-2 agonists/M3 antagonists for the treatment of COPD.

ABSTRACT

This paper describes the successful design and development of dual pharmacology ß-2 agonists-M3 antagonists, for the treatment of chronic obstructive pulmonary disorder using the principles of 'inhalation by design'. A key feature of this work is the combination of balanced potency and pharmacodynamic duration with desirable pharmacokinetic and material properties, whilst keeping synthetic complexity to a minimum.
