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.
The present invention relates to an orthogonal gene switch for regulating the expression of a desired gene. The gene switch comprises a chimeric transcription factor that does not respond to endogenous ligands, and a ligand that is capable of activating the chimeric transcription factor but not endogenous transcription factors. The present invention also relates to the method of constructing the orthogonal gene switch.
This invention relates to the treatment of hypertension, cardiac dysfunction or stroke by the administration of an estrogen receptor beta (ER&bgr;) selective agonist either as a single agent, or in combination with other agents.
