摘要:
The design and synthesis of a new series of high efficacy beta(2)-agonists devoid of the key benzylic alcohol present in previously described highly efficacious beta(2)-agonists is reported. A hypothesis for the unprecedented level of efficacy is proposed based on considerations of beta(2)-adrenoceptor crystal structure, other biophysical data and modeling studies. (C) 2011 Elsevier Ltd.
