General Description

A cell-permeable, bioavailable, non-toxic purpurin analog that directly binds to GDH1 (Glutamate dehydrogenase 1; K_d= 30 µM) and inhibits its activity in a mixed mode manner (IC₅₀= 23 µM). Displays selectivity over other NADPH-dependent enzymes such as 6-phosphogluconate dehydrogenase (6PGD) and fumarate hydratase (FH). Show to appreciably decrease intracellular fumarate levels, lessen glutathione peroxidase (GPx) activity and elevate mitochondrial ROS levels. Preferentially arrests cancer cell proliferation of H1299, MDA-MB231 and primary leukemia cells over nonmalignant, proliferating human cells. Significantly decreases tumor growth and masses in H1299-xenograft tumor mouse models (30 mg/kg, i.p., q.d.).A cell-permeable, bioavailable, non-toxic purpurin analog that directly binds to GDH1 (Glutamate dehydrogenase 1; K_d= 30 µM) and inhibits its activity in a mixed mode manner (IC₅₀= 23 µM).
