Abstract

Among type I photosensitizers, stable organic radicals are superior candidate molecules for hypoxia-overcoming photodynamic therapy. However, their wide applications are limited by complicated preparation processes and poor stabilities. Herein, a nitroxide radical was simply synthesized by introducing a commercially available "TEMPO" moiety. The radical exhibits efficient type-I ROS generation and appreciable photo-cytotoxicity under hypoxia, which open up a new avenue for the exploration of a novel and efficient type-I photosensitizer.

利用稳定自由基作为 "电子供体"，开发用于高效 I 型光动力疗法的自由基光敏剂。

在 I 型光敏剂中，稳定的有机自由基是克服缺氧的光动力疗法的理想候选分子。然而，复杂的制备过程和较差的稳定性限制了它们的广泛应用。在此，我们通过引入市售的 "TEMPO "分子，简单地合成了一种亚硝基自由基。该自由基在缺氧条件下具有高效的 I 型 ROS 生成能力和明显的光毒性，为探索新型高效 I 型光敏剂开辟了一条新途径。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
