Molidustat(BAY 85-3934) Usage And Synthesis

Description

Hypoxia-inducible factor (HIF) is the major transcription factor involved in erythropoietin gene expression. Because oxygen-dependent degradation of the α subunit of HIF suppresses erythropoietin expression, stimulation of erythropoiesis by agents that prevent degradation of HIF has been one strategy for managing anemia. BAY 85-3934 stabilizes HIF from degradation in the proteasome by inhibiting HIF-1α prolyl hydroxylase (IC₅₀ = 0.49 μM). Inhibition of HIF prolyl hydroxylase by BAY 85-3934 has been shown to increase endogenous production of erythropoietin. This compound has been investigated in clinical trial for treatment of patients with anemia associated with chronic kidney disease and/or end-stage renal disease.

in vitro

the ic50 values were found to be dependent on the 2-oxoglutarate concentration in the reaction buffer. by lowering the 2-oxoglutarate concentration from 20 μm to 0.3 μm, the potency of the test compound increased up to 10-fold. variation of the concentrations of fe2+ and ascorbate in the reaction buffer by factors of 30 and 200, respectively, did not alter the potency of the inhibitor by more than 2-fold [1].

in vivo

in repeat dosing of bay 85-3934, hemoglobin levels were increased compared with animals in vehicle group, while endogenous epo remained within the normal physiological range. bay 85-3934 therapy was also effective in the treatment of renal anemia in rats with impaired kidney function and, unlike treatment with rhepo, resulted in normalization of hypertensive blood pressure in a rat model of ckd [1].

IC 50

480 nm, 280 nm, and 450 nm for phd1, phd2, and phd3, respectively.
