Tetrahydrofluorenones with conformationally restricted side chains as selective estrogen receptor beta ligands
摘要:
A series of 2-9a bridged tetrahydrofluorenone derivatives were prepared which exhibited significant binding affinity for ER beta and were highly selective. (c) 2006 Elsevier Ltd. All rights reserved.
The discovery of tetrahydrofluorenones as a new class of estrogen receptor β-subtype selective ligands
摘要:
Synthesis and derivatization of a series of substituted tetrahydrofluorenone analogs giving potent, ERbeta subtype selective ligands are described. Several analogs possessing ERbeta binding affinities comparable to 17beta-estradiol but with greater than 75-fold selectivity over ERalpha are reported.
The present invention relates to compounds and derivatives thereof, their synthesis, and their use as estrogen receptor modulators. The compounds of the instant invention are ligands for estrogen receptors and as such may be useful for treatment or prevention of a variety of conditions related to estrogen functioning including: bone loss, bone fractures, osteoporosis, cartilage degeneration, endometriosis, uterine fibroid disease, hot flashes, increased levels of LDL cholesterol, cardiovascular disease, impairment of cognitive functioning, cerebral degenerative disorders, restinosis, gynacomastia, vascular smooth muscle cell proliferation, obesity, incontinence, and cancer, in particular of the breast, uterus and prostate.

1,5-disubstituted-2-hydroxy-gibbatetraen-6-ones are useful as estrogen receptor modulators and as precursors to estrogen receptor modulators. The current invention provides a method for the synthesis of 1,5-disubstituted-2-hydroxy-gibbatetraen-6-ones from simple indanone starting materials via a Robinson-type annulation followed by an internal alkylation reaction. This invention further describes the novel use of a fluoroethyl substituent as a latent alkylating group for an internal cyclization reaction.
