Abstract:
The design and profile of a series of saligenin containing long acting beta(2)-adrenoreceptor agonists is described. Evaluation of these analogues using a guinea-pig tissue model demonstrates that analogues within this series have significantly longer durations of action than salmeterol and have the potential for a once daily profile in human.
