Lutetium texaphyrin: A photocatalyst that triggers pyroptosis via biomolecular photoredox catalysis
Proceedings of the National Academy of Sciences of the United States of AmericaSignificance Photon-controlled pyroptosis activation (PhotoPyro) holds promise for cancer immunotherapy by selectively triggering cell death. Here, we report that biomolecular photoredox catalysis in cells contributes to PhotoPyro.

Deal;Photoredox Catalysis for the Cycloaddition Reactions
ChemCatChem, 2020 AbstractCycloaddition reaction is a powerful tool for the synthesis of cyclic structures in a green way. High‐energy ultraviolet (UV) light was strictly required for the traditional photochemical processes. However, in the past ten years, discovery of photoredox catalysis for the cycloaddition reactions have attracted significant attention.

Switching on elusive organometallic mechanisms with photoredox catalysis [PDF]
Nature, 2015 Transition-metal-catalysed cross-coupling reactions have become one of the most used carbon-carbon and carbon-heteroatom bond-forming reactions in chemical synthesis. Recently, nickel catalysis has been shown to participate in a wide variety of C-C bond-forming reactions, most notably Negishi, Suzuki-Miyaura, Stille, Kumada and Hiyama couplings ...

Asymmetric 1,4-functionalization of 1,3-enynes via dual photoredox and chromium catalysis
Nature Communications, 2022 In contrast to the better-studied ionic pathway, radical-involved asymmetric 1,4-functionalization of 1,3-enynes remains a prominent challenge. Here, the authors describe the asymmetric three-component 1,4-dialkylation of 1,3-enynes via dual photoredox ...
