The more efficient conjugation of the QIs to GSH may have reduced covalent modification of cellular macromolecules, like ER proteins Grp78/Bip (Xu et al., 2015), microsomal GST (Weis et al., 1992), and PDI ( Although reactive QI formation has been associated with AQ-induced (cyto)toxicity in vitro ( in vivo (Wink et al., 2014, 2017)
