IC50: 22 nM (PHD2)[2]
IOX2 (0, 10, 25, and 50 μM) dose-dependently inhibits collagen-related peptide (CRP; 0.25 μg/mL) or thrombin (0.03 U/mL)-induced platelet aggregation and ATP release. But IOX2 doesn’t affect P-selectin expression and the surface levels of glycoprotein (GP)Ibα, GPVI, or αIIbβ3[1].
IOX2 also inhibits the spreading of platelets on fibrinogen or collagen and clot retraction[1].
IOX2 (50 μM; 24 h) increases the transcription level of VEGF-A and BNIP3 in Normal human epidermal keratinocytes (NHEK) and Normal human dermal fibroblasts (NHDF), when grown under normoxia and hypoxia condition[2].
