Ferroptosis, a newly discovered form of regulated cell death, is emerging as a promising approach to tumor therapy. However, the spatiotemporal control of cell-intrinsic Fenton chemistry to modulate tumor ferroptosis remains challenging. Here, we report an oxazine-based activatable molecular assembly (), which is capable of triggering the lysosomal dysfunction-mediated Fenton pathway with excellent spatiotemporal resolution via near-infrared (NIR) light to evoke ferroptosis.

Article Synopsis
  • Hydrogen polysulfides (HS) play a crucial role as signaling mediators in various physiological processes, but their specific functions in diseases like nonalcoholic fatty liver disease (NAFLD) remain unclear due to detection challenges.
  • A new strategy was developed to create a ratiometric probe that selectively detects HS with improved selectivity, stability, and compatibility in biological systems.
  • This probe was successfully used for the first time to image HS in a NAFLD cell model, uncovering HS generation pathways that could provide insights for future drug development targeting this liver disease.

Herein, a novel two-photon ratiometric fluorescence assay was proposed for monitoring endogenous steroid sulfatase (STS) activity, which could be applied for the ratiometric imaging of STS activity in the endoplasmic reticulum of living cells and tissues and also could be used to distinguish estrogen-dependent tumor cells from other types of cells.

Development of a facile but high-efficient small organic molecule-based photothermal therapy (PTT) in the in vivo transparent window (800-900 nm) has been regarded as a minimally invasive and most promising strategy for potential clinical cancer treatment. Phthalocyanine (Pc) molecules with remarkable photophysical and photochemical properties as well as high extinction coefficients in the near-infrared region are highly desirable for PTT, but as far satisfying single-component Pc-based PTT within the in vivo transparent window (800-900 nm) has very rarely been reported. Herein, inspired by the self-assembly algorithm of natural bacteriochlorophylls c, d, and e, biomimetic self-assembling tetrahexanoyl Pc Bio-ZnPc with outstanding light-harvesting capacity was demonstrated to exhibit excellent PTT efficacy evidenced by both in vitro and in vivo results, within the biological transparent window.
