Triazolo-tetrahydrofluorenones as selective estrogen receptor beta agonists
摘要:
Several tetrahydrofluorenones with a triazole fused across C7-C8 showed high levels of ER beta-selectivity and were found to be potent ER beta-agonists. As a class they demonstrate improved oral bioavailability in the rat over a parent class of 7-hydroxy-tetrahydrolluorenones. The most selective agonist displayed 5.7 nM affinity and 333-fold selectivity for ER beta. (c) 2006 Elsevier Ltd. All rights reserved.
Estrogen receptor β-subtype selective tetrahydrofluorenones: Use of a fused pyrazole as a phenol bioisostere
摘要:
Synthesis of a series of fused pyrazole tetrahydrofluorenone analogs which are potent, ERP subtype selective ligands is described. Analogs possessing subnanomolar ERP binding, greater than 100-fold ER beta-selectivity, and oral bioavailability are reported. (c) 2006 Elsevier Ltd. All rights reserved.
