Malachite green oxalate is a triphenylmethane dye which can be used to detect the release of phosphate in enzymatic reactions. Malachite green oxalate is also a potent and selective inhibitor of IKBKE, and inhibits its downstream targets such as IκBα, p65 and IRF3. Malachite green oxalate exhibits antitumor activity in vitro and in vivo.
