Abstract:
:In this issue of Cell Chemical Biology, Shah et al. (2019) report an in vitro, high-throughput assay that predicts the ability of compounds to suppress peroxidation of phospholipids. This approach provides a way to design and optimize targeted antioxidants that suppress specific oxidative event in cells, potentially overcoming previous failures with generic antioxidants.

评论,杂志文章abstract::USP7 is a deubiquitinating enzyme that plays a pivotal role in multiple oncogenic pathways and therefore is a desirable target for new anti-cancer therapies. However, the lack of structural information about the USP7-inhibitor interactions has been a critical gap in the development of potent inhibitors. USP7 is unique...
