On May 20, 2020, Bao, Xia-Zhen; Wang, Qi; Ren, Xiao-Rong; Dai, Fang; Zhou, Bo published an article.Name: 1,4-Dimethoxybenzene The title of the article was A hydrogen peroxide-activated Cu(II) pro-ionophore strategy for modifying naphthazarin as a promising anticancer agent with high selectivity for generating ROS in HepG2 cells over in L02 cells. And the article contained the following:
Targeting redox vulnerability of cancer cells by pro-oxidants capable of generating reactive oxygen species (ROS) has surfaced as an important anticancer strategy. Due to the intrinsic narrow therapeutic window and other dangerous side effects of ROS generation, it is highly needed and challenging to develop pro-oxidative anticancer agents (PAAs) with high selectivity for generating ROS in cancer cells. Herein we report a hydrogen peroxide (H2O2)-activated Cu(II) pro-ionophore strategy to develop naphthazarin (Nap) as such type of PAAs based on the H2O2-mediated conversion of boronate to free phenol. The boronate-protected Nap (PNap) can exploit increased levels of H2O2 in HepG2 cells to in situ release Nap followed by its efflux via conjugation with reduced glutathione (GSH), allowing that the Nap-GSH adduct works as a Cu(II) ionophore to induce continuously GSH depletion via a reduction-dependent releasing of Cu(I) by GSH. This strategy endows PNap with the unprecedented ability to hit multi-redox characteristics (increased levels of H2O2, GSH and copper) of HepG2 cells, leading to ROS generation preferentially in HepG2 cells along with their selective death. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Name: 1,4-Dimethoxybenzene
