Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

open access: yesAdvanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

EccDNA‐Driven VPS41 Amplification Alleviates Genotoxic Stress via Lysosomal KAI1 Degradation

open access: yesAdvanced Science, EarlyView.
Following ionizing radiation, eccDNA‐mediated VPS41 amplification slightly increases its expression but fails to prevent apoptosis. Introducing exogenous eccDNA or VPS41 enhances VPS41‐KAI1 interaction, promoting lysosomal degradation of KAI1. This process inhibits apoptotic signaling, enhancing cell survival and resistance to radiation‐induced damage.
