WebCayman's GPX4 Inhibitor Screening Assay Kit provides a robust and easy-to-use platform for identifying novel inhibitors of human GPX4, a negative regulator of the ferroptosis pathway. The assay measures GPX4 indirectly by a coupled reaction with glutathione reductase (GR). A chief drawback of chloroacetamide GPX4 inhibitors is their high chemical reactivity, which imparts them with relatively low proteome-wide selectivity. To test whether ML210 may act in a more selective manner, we performed cellular proteome reactivity profiling experiments using the ML210, RSL3 … See more To identify small-molecule GPX4 inhibitors that do not contain a reactive alkyl chloride warhead, we focused our attention on the nitroisoxazole … See more To understand how ML210 covalently modifies GPX4 without a chloroacetamide warhead, we developed an intact protein mass spectrometry … See more The +434 Da mass of the ML210-derived GPX4 adduct suggests that the final protein-reactive metabolite of ML210 is related to JKE-1674 through the loss of water. In cells, ML210 and JKE-1674 react with cysteine and … See more To investigate how ML210 may give rise in cells to a GPX4-targeting metabolite, we focused our attention on the nitroisoxazole group, which … See more northern quest casino theatre
