Introduction Recent progress in bioorthogonal catalysis introduces innovative chemical methodologies for achieving chemoselective reactions within intricate biological systems. This study unveils the role of FAD (flavin adenine dinucleotide), FMN (flavin mononucleotide), and an array of flavoproteins as atypical photocatalysts that effectively transform Pt IV and Ru II complexes into potentially harmful Pt II or Ru II−OH 2 compounds. With the aid of electron donors and minimal visible light exposure, flavoproteins such as mini singlet oxygen generator (miniSOG) and NADH oxidase (NOX) enable bioorthogonal activation of Pt IV prodrugs. Furthermore, NOX demonstrates Pt IV activation in the absence of light when NADH is present, marking the first recognition of flavoenzymes potentially initiating the activity of Pt IV-based chemotherapeutic drugs.
