Biological Activity
Inhibition of GDH1 activity by R162 treatment results in decreased intracellular fumarate levels, attenuated GPx activity, increased ROS levels, and reduced cell proliferation in H1299 and MDA-MB231 cells, which can be significantly rescued by methyl-α-KG treatment as well as by antioxidant NAC. R162 inhibits cell proliferation and tumor growth potential of human cancer cells[1].
