Description
General description
A cell-permeable benzimidazolopyrazole compound that acts as an active-site binding, iron insensitive, 2-oxoglutarate competitive, reversible and potent inhibitor of PHD1, 2 and 3 isozymes (pKi = 7.91, 7.29 and 7.65, respectively). Displays >100-fold selectivity over FIH (factor inhibiting hydroxylase; pIC₅₀ ~ 4) and minimal affinity towards a panel of receptors, enzymes and kinases. Shown to elevate HIF-1α levels in Hep3B cells and stimulate erythropoietin secretion in mice, and reverse inflammation-induced anemia in rats (100 µM/kg). Shown to inhibit malate dehydrogenase 2 (MDH2) activity and suppress mitochondrial respiration.
