6-Hydroxybenzbromarone 是 Benzbromarone 的主要代谢产物 (metabolite)，比母体化合物具有更长的半衰期和更大的药理效力。6-Hydroxybenzbromarone 是一种 EYA3 抑制剂，IC₅₀ 值为 21.5 μM。6-Hydroxybenzbromarone 是一种血管生成剂，对细胞迁移，肾小管生成和血管生成具有强大的抑制作用。

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 IC 50 value of 21.5 μM. 6-Hydroxybenzbromarone is an angiogenic agent, has strong inhibitory effects on cell migration, tubulogenesis, and angiogenic sprouting.

IC50: 21.5 μM (EYA3); metabolite

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.
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.
has not independently confirmed the accuracy of these methods. They are for reference only.
