Abstract
New, highly selective, glucocorticoid receptor agonists based on an androstane 17β-carbothioate ester scaffold are claimed. Combinations of these steroids with novel long-acting β2 agonists are also claimed. This patent defines potential replacements for fluticasone propionate and the combination of salmeterol and fluticasone propionate (Advair™, Glaxo Wellcome, Inc.).
