Citreoviridin, a toxin from Penicillium citreoviride NRRL 2579, inhibits brain synaptosomal Na+/K+-ATPase whereas in microsomes, both Na+/K+-ATPase and Mg2+-ATPase activities are significantly stimulated in a dose-dependent manner[1]. Citreoviridin inhibits cell proliferation and enhances apoptosis of human umbilical vein endothelial cells[2].
