Comparative molecular field analysis of fenoterol derivatives: A platform towards highly selective and effective β2-adrenergic receptor agonists
摘要:
Purpose: To use a previously developed CoMFA model to design a series of new structures of high selectivity and efficacy towards the beta(2)-adrenergic receptor. Results: Out of 21 computationally designed structures 6 compounds were synthesized and characterized for beta(2)-AR binding affinities, subtype selectivities and functional activities. Conclusion: the best compound is (R,R)-4-methoxy-1-naphthylfelnoterol with K-i beta(2)-AR = 0.28 mu m, K-i beta(1)-AR/K-i beta(2)-AR = 573, EC50cAMP = 3.9 nm, EC50cardio = 16 nm. The CoMFA model appears to be an effective predictor of the cardiomocyte contractility of the studied compounds which are targeted for use in congestive heart failure. (C) 2009 Elsevier Ltd.
