Nonsteroidal Glucocorticoid Agonists: Tetrahydronaphthalenes with Alternative Steroidal A-Ring Mimetics Possessing Dissociated (Transrepression/Transactivation) Efficacy Selectivity
摘要:
The synthesis and biological activity of tetrahydronaphthalene derivatives coupled to various heterocycles are described. These compounds are potent glucocorticoid receptor agonists with efficacy selectivity in an NF kappa B glucocorticoid receptor (GR) agonist assay (representing transrepression effects) over an MMTV GR agonist assay (representing transactivation effects). Quinolones, indoles, and C- and N-linked quinolines are some of the heterocycles that provide efficacy selectivity. For example, the isoquinoline 49D1E2 has NF kappa B agonism with pIC(50) of 8.66 (89%) and reduced efficacy in MMTV agonism (6%), and the quinoline 55D1E1 has NF kappa B agonism with pIC(50) of 9.30 (101%) and reduced efficacy in MMTV agonism with pEC(50) of 8.02 (47%). A description of how a compound from each class is modeled in the active site of the receptor is given.
