BioAssay: AID 1066393

Competitive inhibition of ER-alpha (unknown origin)-GRIP1 interaction expressed in human HepG2 cells assessed as change in reporter gene activity after 40 hrs in presence of estradiol relative to control

A series of unsymmetrically substituted biphenyl compounds was designed as alpha helical proteomimetics with the aim of inhibiting the binding of coactivator proteins to the nuclear hormone receptor coactivator binding domain. These compounds were synthesized in good overall yields in seven steps starting from 2-bromoanisole. The final products were evaluated using cotransfection reporter gene more ..

Title: 4,4'-unsymmetrically substituted 3,3'-biphenyl alpha helical proteomimetics as potential coactivator binding inhibitors.

Abstract: A series of unsymmetrically substituted biphenyl compounds was designed as alpha helical proteomimetics with the aim of inhibiting the binding of coactivator proteins to the nuclear hormone receptor coactivator binding domain. These compounds were synthesized in good overall yields in seven steps starting from 2-bromoanisole. The final products were evaluated using cotransfection reporter gene assays and mammalian two-hybrid competitive inhibition assays to demonstrate their effectiveness as competitive binding inhibitors. The results from this study indicate that these proteomimetics possess the ability to inhibit coactivator-receptor interactions, but via a mixed mode of inhibition.
