Landomycins as glutathione-depleting agents and natural fluorescent probes for cellular Michael adduct-dependent quinone metabolism
Abstract
Landomycins are promising anti-cancer agents with the potential to bypass common resistance pathways, but their mechanism of action remains incompletely understood. Here a mechanism is proposed involving intracellular sequential thiol-Michael and oxidation reactions, which depletes endogenous thiols and induces reactive oxygen species formation.
