BODIPY染料往往是高荧光的,但它们的发射可以通过添加具有适当氧化电位的取代基来减弱。像这样的取代基有电子进入光激发的BODIPY,淬灭它们的荧光,从而产生相对长寿命的三重态。当这些三重态与3O2相互作用时形成单线态氧。在组织中,这会导致被照射区域的细胞损伤,这是光动力疗法(PDT)的基础。目前批准用于临床的PDT药物不具有BODIPY,但有很多理由相信这种情况会改变。本文综述了BODIPY光动力治疗染料的特性及其在相关领域的应用。
BODIPY dyes tends to be highly fluorescent, but their emissions can be attenuated by adding substituents with appropriate oxidation potentials. Substituents like these have electrons to feed into photoexcited BODIPYs, quenching their fluorescence, thereby generating relatively long-lived triplet states. Singlet oxygen is formed when these triplet states interact with 3O2. In tissues, this causes cell damage in regions that are illuminated, and this is the basis of photodynamic therapy (PDT). The PDT agents that are currently approved for clinical use do not feature BODIPYs, but there are many reasons to believe that this situation will change. This review summarizes the attributes of BODIPY dyes for PDT, and in some related areas.
