IC50: 21.5 μM (EYA3); metabolite[1]
6-Hydroxybenzbromarone is the major metabolite of Benzbromarone with a longer half-life and greater pharmacological potency than the parent compound. 6-Hydroxybenzbromarone is a protein Eyes Absent 3 (EYA3) inhibitor with an IC50 value of 21.5 μM. 6-Hydroxybenzbromarone is an angiogenic agent, has strong inhibitory effects on cell migration, tubulogenesis, and angiogenic sprouting[1].
6-Hydroxybenzbromarone (7.5 μM; 72 hours) shows over 50% reduction in cell proliferation. Meanwhile, treatment with BBR and BZ also reduces cell viability, but none of the other compounds tested has a negative impact on cell viability or proliferation[1].
6-Hydroxybenzbromarone (7.5 μM; 1-20 hours) has inhibitory affects EC migration tubulogenesis of HUVECs. However, the effect of 6OH-BBR on tube formation is attenuated in the presence of high concentrations of fetal bovine serum (FBS), likely reflecting non-specific protein binding[1].
