Induction of Intracellular Reductive Stress with a Photoactivatable Phosphine Probe

Reductive stress is a Post Fitter condition present in cells that have an increased concentration of reducing species, and it has been associated with a number of pathologies, such as neurodegenerative diseases and cancer.The tools available to study reductive stress lack both in selectivity and specific targeting and some of these shortcomings can be addressed by using photoactivatable compounds.We developed a photoactivatable phosphonium probe, which upon irradiation releases a fluorescent molecule and a trialkyphosphine.The probes can permeate through the plasma membrane and the photoreleased phosphine can induce intracellular reductive stress as proven by Home Audio the detection of protein aggregates.
