Elevated GSH and HO in cancer cells is sometimes doubted due to their contrary reactivities. Here, we construct a dual-responsive fluorescent probe to confirm the conclusion, and employ this to exploit a redox-inducible DNA interstrand crosslink (ICL) precursor. It crosslinks DNA upon activation by GSH and HO, affording an alternative dual-responsive strategy.
癌细胞中升高的 GSH 和 HO 的反应性相反，因此其存在有时会受到质疑。在这里，我们构建了一种双响应荧光探针来证实这一结论，并利用该探针开发了一种氧化还原诱导的 DNA 链间交联（ICL）前体。该前体在 GSH 和 HO 的激活下交联 DNA，提供了一种替代的双响应策略。
