Biological Activity
Kd: <50 nM (HIF-2α)[1]
PT-2385 (PT2385) inhibits expression of HIF-2α regulated genes in a dose dependent manner in vivo. Tumor is regressed with PT-2385 (3 and 10 mg/kg, p.o., b.i.d. dose) in 786-O xenograft. PT-2385 (1,3 and 10 mg/kg) also inhibits tumor-derived VEGFA protein levels. PT-2385 (10 mg/kg) treatment reduces proliferation (Ki67) and angiogenesis (CD-31)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

WT naïve CD4+ T cells are activated by CD3/CD28 (2/1 μg/mL) in the presence of HIF-2α inhibitor PT2385 for 2 days, or activating WT iTreg cells are treated with 10 μM PT2385, and HIF-1α levels determined. Treatment of activating WT CD4+ T cells with PT2385 leads to dose-dependent upregulation of HIF-1α. PT2385 also increases the level of HIF-1α induction in activated WT iTreg cells.
