WAY-204688

Research use only, not for human use.

WAY-204688 is a selective and orally active estrogen receptor inhibitor of NF-κB transcriptional activity (IC50 = 122 nM in HAECT-1 cells).

WAY-204688 is a selective and orally active estrogen receptor inhibitor of NF-κB transcriptional activity (IC50 = 122 nM in HAECT-1 cells).(In Vitro):WAY-204688 displaces [3H]E2 from the ERα ligand-binding domain protein (C50=2.43 μM) and from the ERβ ligand-binding domain protein (IC50=1.5 μM).(In Vivo):WAY-204688 (5 mg/kg per day, p.o.) inhibits pro-inflammatory genes including MHI, VCAM-1, RANTES, and TNF-α and induces the gene products and uterine wet weight. WAY-204688 (0.3 mg/kg, p.o.) is active in the Lewis rat adjuvant-induced arthritis model .

WAY-204688 is ER-dependenrt (activity seen only when hER is coexpressed with NF-κB-luciferase in human aortic endothelial cell lines (HAECT-1) cells). The interaction of WAY-204688 with ERα and ERβ is examined in vitro. WAY-204688 displaces [3H]E2 from the ERα ligand binding domain protein (LBD) with IC50=2.43 μM and from the ERβ ligand binding domain protein(LBD) with IC50=1.5 μM.

WAY-204688 (5 mg/kg per day, po daily for 5 weeks) is evaluated in vivo for the ability to inhibit four proinflammatory genes (MHC, invariant chain (MHI), VCAM-1, RANTES, and TNF-α). The effect of WAY-204688 on induction of the gene products and on uterine wet weight is compared to that of 17α-ethinyl 17β-estradiol (EE at 10 μg/kg per day) in the same paradigm. Further characterization of WAY-204688 is carried out in several preclinical models of inflammatory disease. In the Lewis rat adjuvant-induced arthritis model (AIA), WAY-204688 is active at a dose of 0.3 mg/kg per day, po.
