Synthesis and activity of a new class of pathway-selective estrogen receptor ligands: Hydroxybenzoyl-3,4-dihydroquinoxalin-2(1H)-ones
摘要:
The anti-inflammatory activity of non-selective estrogens has been attributed to their ability to antagonize the activity of nuclear factor KB (NF-kappa B), a known mediator of inflammatory responses. Here we report the identification of a potent new class of pathway-selective ER ligands that selectively antagonize NF-kappa B functional activity, while exhibiting a lack of classical estrogenic effect.

This paper reports our recent results from synthesis of some useful heterocycles, for example oxazolidinones, indoles, and quinoxalinones, by transition metal-catalyzed cascade processes. The scope and limitations of these procedures and the reaction mechanism for formation of the heterocycles are also discussed.
A general, straightforward, and practicalaccess to multi-substituted chiral quinoxalin-2-ones has been achieved based on the copper(I) chloride-dimethylethylenediamine (DMEDA) catalyst system. With the use of 1 mol% copper(I) chloride, structurally diverse quinoxalin-2-ones were generated with high optical purity from readily available starting materials, 2-haloanilines and α-amino acids, in a one-pot
