Biochem/physiol Actions

Salmeterol xinafoate is a β2 adrenoceptor agonist with longer lasting bronchodilation and anti-inflammatory effects. It relaxes the airway smooth muscles, stabilizes mast cells and regulates the release of histamine. Salmetrol is particularly effective in treatment of mild asthma, chronic obstructive pulmonary disorder.5,6

Haptens are low molecular weight compounds that are non-immunogenic and so must be conjugated to carrier molecules to elicit an immune response. Doses of 50-1000 microg protein conjugate have been suggested for immunisation of rabbits with hapten-protein immunogens. Although larger...

Recently available G-protein coupled receptor (GPCR) structures and biophysical studies suggest that the difference between the effects of various agonists and antagonists cannot be explained by single structures alone, but rather that the conformational ensembles of the proteins need to...

Transmembrane domains (TMDs) I, II, and VII of the beta2-adrenergic receptor (beta2AR) were replaced, individually or in combination, with the corresponding regions of the beta1AR, and vice versa. The beta2-selective binding of salmeterol was not affected by the exchange of...

Vilanterol trifenatate (vilanterol) is a novel, long-acting β(2)-adrenoceptor (β(2)-AR) agonist with 24 h activity. In this study, we describe the preclinical pharmacological profile of vilanterol using radioligand binding and cAMP studies in recombinant assays as well as human and guinea...

Indacaterol is a once-daily, long-acting β(2)-agonist bronchodilator that improves dyspnoea and health status in patients with moderate-to-severe COPD. While its bronchodilator effects have been shown to be maintained in different patient subgroups, effects on clinical outcomes in certain subgroups are...
