2,3-BIS(4-HYDROXYPHENYL)-PROPIONITRILE Usage And Synthesis

Description

DPN (1428-67-7) is a potent estrogen ERβ receptor agonist. Displays a 70-fold selectivity over ERα, EC50 = 0.85 and 66 nM, respectively.1 Regulates expression of GluR1, 2 and 3 in rat hippocampus.2 Ameliorates portal hypertension in a carbon tetrachloride-induced liver cirrhosis rat model.3 Stimulates proliferation of androgen-independent prostate cancer cell line PC-3 via a novel pathway involving ERβ-mediated activation of β-catenin.4 A useful tool for elucidating the biological function of ERβ.5

Uses

2,3-Bis(4-hydroxyphenyl)propionitrile is an estrogen receptor β and α specific with pro- and anti-nociceptive actions in mice.

Definition

ChEBI: A nitrile that is acetonitrile in which one of the hydrogens is replaced by a 4-hydroxyphenyl group while a second hydrogen is replaced by a 4-hydroxybenzyl group. It is a specific agonist for estrogen receptor beta (ERbeta).

Biological Activity

Highly potent estrogen ER β receptor agonist with a 70-fold selectivity over ER α (EC 50 values are 0.85 and 66 nM respectively). Relaxes mesenteric arteries in vitro .

Biochem/physiol Actions

2,3-Bis(4-hydroxyphenyl)-propionitrile (Diarylprepionitrile, DPN) is an ERβ-selective agonist; IC50 = 15nM. DPN protects WT and ARKO mice and significantly decreases IL-1β following LPS treatment in young adult-derived microglia. PPT (Cat. No.H6036, ERa agonist) enhances cell proliferation, while DPN inhibits it. PPT increases Bcl-2 expression, while DPN decreases it. DPN also elevates Bax expression. DPN induces a dose-dependent increase on vitellogenin synthesis. PPT and DPN are effective in dynamically, but differentially regulating intracellular calcium signaling in hippocampal neurons. DPN is more efficacious than PPT in potentiating a physiological concentration of glutamate-induced intracellular Ca2+ rise in these neurons. DPN prevents the development of prostatic hyperplasia and inflammation in testosterone-treated LuRKO mice.

storage
