Constrained phytoestrogens and analogues as ERβ selective ligands
摘要:
A new series of ERbeta (ERbeta) selective ligands has been prepared. One of the compounds 6, structurally related to the phytoestrogen apigenin 4, displays a binding preference for ERbeta over ERalpha of over 40-fold. In addition to its binding selectivity, 6 was able to potently induce metallothionein (an ERbeta specific response in human SAOS-2 cells) while demonstrating low potency in an ERalpha dependant ERE-tk luciferase assay in MCF-7 cells. Such receptor and cell selectivity could make 6 a useful molecular probe for better understanding the role of ERbeta in mammalian physiology. (C) 2003 Elsevier Science Ltd. All rights reserved.

benzodiazepines are nonselective and suffer from numerous side effects. Upon the identification of receptor subtypes, we set out to discover selective agents with the anticipation that these agents would have superior therapeutic potential. Herein, we describe the synthesis and biological evaluation of substituted 7,8,9,10-tetrahydroimidazo[1,2-c]pyrido[3,4-e]pyrimidin-5(6H)-ones and disclose that these compounds
Hepatitis C virus inhibitors having the general formula
are disclosed. Compositions comprising the compounds and methods for using the compounds to inhibit HCV are also disclosed.

practical and highly regioselective chloro- and bromo-trifluoromethylthiolation of sulfur ylides is reported using a difunctionalization strategy. In the reaction sequence, sulfur ylides presumably react with an electrophilic trifluoromethylthiolating reagent to generate an α-SCF3 substituted sulfonium salt intermediate, which then undergoes a substitution with nucleophilic halogens.
