CETZOLE Analogs as Potent Ferroptosis Inducers and Their Target Identification Using Covalent/Affinity Probes.

Ferroptosis is a recently discovered cell death mechanism triggered by iron-dependent elevation of reactive oxygen species leading to lipid membrane peroxidation. We previously reported the development of a new class of ferroptosis inducers referred to as CETZOLEs with CC values in the low micromolar range. Structure-activity relationship study of these compounds led to the development of more potent analogs with CC values in the nanomolar range.
