AKB-6899, a prolyl hydroxylase domain 3 (PHD3) inhibitor, is a selective HIF-2α stabilizer. AKB-6899 also increases soluble form of the VEGF receptor (sVEGFR-1) production from GM-CSF-treated macrophages, and has antitumor and antiangiogenic effects[1].
AKB-6899 (10 μM; 24 hours) increases the leves of HIF-2α protein, with no corresponding increase in HIF-1α. AKB-6899 also increases soluble form of the VEGF receptor (sVEGFR-1) production from GM-CSF-treated macrophages, with no effect on HIF-1α accumulation or VEGF production[1].
AKB-6899 (17.5 mg/kg; i.p.; 3 times per week; for 16 days) treatment significantly reduces tumor growth in a murine melanoma model[1].

Stabilization of HIF-2α induces sVEGFR-1 production from tumor-associated macrophages and decreases tumor growth in a murine melanoma model
J Immunol 2012 Sep 15;189(6):3168-77.PMID:22869907DOI:PMC3436995
Macrophage secretion of vascular endothelial growth factor (VEGF) in response to hypoxia contributes to tumor growth and angiogenesis. In addition to VEGF, hypoxic macrophages stimulated with GM-CSF secrete high levels of a soluble form of the VEGF receptor (sVEGFR-1), which neutralizes VEGF and inhibits its biological activity. Using mice with a monocyte/macrophage-selective deletion of hypoxia-inducible factor (HIF)-1α or HIF-2α, we recently demonstrated that the antitumor response to GM-CSF was dependent on HIF-2α-driven sVEGFR-1 production by tumor-associated macrophages, whereas HIF-1α specifically regulated VEGF production. We therefore hypothesized that chemical stabilization of HIF-2α using an inhibitor of prolyl hydroxylase domain 3 (an upstream inhibitor of HIF-2α activation) would increase sVEGFR-1 production from GM-CSF-stimulated macrophages. Treatment of macrophages with the prolyl hydroxylase domain 3 inhibitor AKB-6899 stabilized HIF-2α and increased sVEGFR-1 production from GM-CSF-treated macrophages, with no effect on HIF-1α accumulation or VEGF production. Treatment of B16F10 melanoma-bearing mice with GM-CSF and AKB-6899 significantly reduced tumor growth compared with either drug alone. Increased levels of sVEGFR-1 mRNA, but not VEGF mRNA, were detected within the tumors of GM-CSF- and AKB-6899-treated mice, correlating with decreased tumor vascularity. Finally, the antitumor and antiangiogenic effects of AKB-6899 were abrogated when mice were simultaneously treated with a sVEGFR-1 neutralizing Ab. These results demonstrate that AKB-6899 decreases tumor growth and angiogenesis in response to GM-CSF by increasing sVEGFR-1 production from tumor-associated macrophages. Specific activation of HIF-2α can therefore decrease tumor growth and angiogenesis.
