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). WebS3 The GPX4 inhibitor ML210-yne was synthesized according to reference with a yield of 30%. 1 Fluorophore ENBO-N 3 was synthesized according to reference, 2 conditions. After the reaction, the ...
