Sweetened Alkylated Verdazyls Effectively Kill Cancer Cells under Light Irradiation
TL;DR: In this paper , two conjugates of carbohydrates with 1,2,4,6,substituted, 1,4−dihydro, 1.2,2−4,5−tetrazin−3(2H)ones (AlkVZs) demonstrated high oxygen-independent cytotoxicity on PC-3 and Jurkat cancer cells under light irradiation combining with low toxicity in the dark.
Journal ArticleDOI

Unveiling the role of chemical and electronic structure in plasmon-assisted homolysis of alkoxyamines
Darya E. Votkina,Pavel V. Petunin,Elena Miliutina,Andrii Trelin,Oleksiy Lyutakov,Václav Švorčík,Gérard Audran,Jeffrey Havot,Rashid R. Valiev,Rashid R. Valiev,Lenara I. Valiulina,Jean-Patrick Joly,Olga Guselnikova,Sylvain R. A. Marque,Pavel S. Postnikov +14 more
TL;DR: In this article, the kinetic data revealed the dependence of plasmonic homolysis rate constant (kd) with the HOMO energy of five alkoxyamines (AAs) with different chemical and electronic structures using electron paramagnetic resonance (EPR), which suggested the key role of intramolecular excitation mechanism supported by the TDFDT calculations, additional spectroscopic characterization, and control experiments.
Journal ArticleDOI
