Description

General description

A cell-permeable tetrahydroquinazolinone derivative that acts as a highly selective inhibitor of galactokinase 1 (GALK1, IC₅₀ = 4.7 µM in a GALK-ATP depletion assay). The inhibition appears to be competitive with respect to ATP and uncompetitive with respect to galactose. Exhibits higher affinity for GALK1-galactose complex than the free enzyme. Does not affect GALK2 activity even at higher concentrations (~ 40 µM) and has no significant effect on all other protein kinases profiled. Shown to reduce Gal-1-phosphate levels in patient derived fibroblasts without affecting their viability. Displays good plasma (t_1/2 >60 min) and microsomal stability (t_1/2
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.
