설명

일반 설명

A cell-permeable, bioactive, non-toxic oxadiazolohydroxyamidine based compound that acts as a potent, selective and competitive inhibitor of indoleamine 2,3-dioxygenase (IDO; IC₅₀ = 67 nM for hIDO). Reversibly binds to the catalytically active heme iron (Fe²⁺) and is inactive towards closely related tryptophan 2,3-dioxygenase (TDO; IC₅₀ >10 µM). Shown to dose-dependently decrease kynurenine levels (IC₅₀ = 19 & 46 nM in HeLa treated with IFN-γ & B16-GM-CSF melanoma cells, respectively) and suppress B16-GM-CSF xenograft tumor growth in C57BL/6 mice (75 mg/kg, s.c., b.i.d.). Though orally bioavailable, but undergoes a rapid clearance (t_1/2<0.5 h).

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
