Peroxiredoxins (Prx), a family of small non-seleno peroxidases, are important regulators for cellular reactive oxygen species (ROS), which contribute to many signaling pathways and pathogenesis of diseases. Targeting redox homeostasis is being developed as a promising therapeutic strategy for many diseases such as cancers. This mini-review attempts to focus on our recent discoveries on adenanthin as the first natural molecule to specifically target the resolving cysteines of Prx I and Prx II and thus inhibit their peroxidase activities, and its role in differentiation induction in vitro and in vivo of acute myeloid leukemic cells.
