Photocatalytic Superoxide Radical Generator that Induces Pyroptosis in Cancer Cells

Journal of the American Chemical Society, Год журнала: 2022, Номер 144(25), С. 11326 - 11337

Опубликована: Июнь 16, 2022

Pyroptosis, a newly characterized form of immunogenic cell death, is attracting increasing attention as promising approach to cancer immunotherapy. However, biocompatible strategies activate pyroptosis remain rare. Here, we show that photocatalytic superoxide radical (O2-•) generator, NI-TA, triggers in cells. NI-TA was designed take advantage an intramolecular triplet-ground state splitting energy modulation approach. Detailed studies revealed the triggered by under conditions photoexcitation proceeds through caspase-3/gasdermin E (GSDME) pathway rather than via canonical processes involving caspase-1/gasdermin-D (GSDMD). found function partial-O2-recycling mode action and trigger provide for effective ablation even hypoxia (≤2% O2). In case T47D 3D multicellular spheroids, good antitumor efficiency stemness inhibition are achieved. This work highlights how chemistry may be leveraged develop pyroptosis-inducing agents.

Chemically modified biomacromolecules─i.e., proteins, nucleic acids, glycans, and lipids─have become crucial tools in chemical biology. They are extensively used not only to elucidate cellular processes but also industrial applications, particularly the context of biopharmaceuticals. In order enable maximum scope for optimization, it is pivotal have a diverse array biomacromolecule modification methods at one's disposal. Chemistry has driven many significant advances this area, especially recently, numerous novel visible-light-induced photochemical approaches emerged. these reactions, light serves as an external source energy, enabling access highly reactive intermediates under exceedingly mild conditions with exquisite spatiotemporal control. While UV-induced transformations on biomacromolecules date back decades, visible unmistakable advantage being considerably more biocompatible, spectrum visible-light-driven now available, chiefly proteins acids. This review will discuss modifications native functional groups (FGs), including functionalization, labeling, cross-linking techniques well utility oxidative degradation mediated by photochemically generated oxygen species. Furthermore, non-native, bioorthogonal FGs be addressed, photoclick chemistry DNA-encoded library synthesis that allow manipulation activity biomacromolecule.
