Structure activity relationships of novel and selective beta1-adrenoreceptor ligands
Mistry, Shailesh Natvarbhai (2009) Structure activity relationships of novel and selective beta1-adrenoreceptor ligands. PhD thesis, University of Nottingham.
Of the numerous l3-blockers clinically available to treat conditions such as angina pectoris, hypertension and heart failure, none possess antagonist activity specific to the beta1-adrenoceptor. Those described as 'cardioselective', such as nebivolol and bisoprolol, generally show less than 50-fold beta1/beta2-selectivity, which can be lost at higher doses. Others, such as propranolol and sotalol are actually more beta2-selective. Overall, a degree of concomitant beta2-adrenoceptor blockade (risking compromised respiratory function and loss of peripheral vasodilatation) by current therapeutic agents precludes their use in patients with disorders such as asthma and peripheral vascular disease.
