PT2385 (PT-2385) 是一种有效的、选择性的、口服活性的 HIF2α 拮抗剂，与 HIF2α PAS-B 结构域 (Kd=50 nM) 结合并破坏 HIF2α/ARNT 二聚体的形成。

PT2385 (PT-2385) is a potent, selective, and orally active antagonist of HIF2α, binds to HIF2α PAS-B domain (Kd=50 nM) and disrupts HIF2α/ARNT dimer formation; allosterically blocks HIF2α dimerization with the HIF1α/2α transcriptional dimerization partner ARNT/HIF1β, disrupts HIF2α, but not HIF1α, heterodimerization with ARNT in Hep3B cells; inhibits the expression of HIF2α-dependent genes, including VEGF-A, PAI-1, and cyclin D1 in ccRCC cell lines and tumor xenografts, also reduces HIF2α mRNA and protein levels in xenograft tumors.Kidney Cancer Phase 2 Clinical(In Vitro):PT-2385 (PT2385) is a selective antagonist of HIF-2 over HIF-1. PT-2385 is inactive for HIF-1α.(In Vivo):PT-2385 (30 or 100 mg/kg; oral gavage; twice daily) result in a rapid, dose-dependent tumor regression.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).
