including the destruction of diseased tissues and tumours. A novel class of photosensitiser, exemplified by DC324, has been designed possessing a modular, low molecular weight and ‘drug-like’ structure which is bioavailable and can be photoactivated by UV-A/405 nm or corresponding two-photon absorption of near-IR (800 nm) light, resulting in powerful cytotoxic activity, ostensibly through the production
光敏剂的光活化可用于引发 ROS 的产生,用于潜在的治疗应用,包括破坏病变组织和肿瘤。以DC324为代表的新型光敏剂被设计成具有模块化、低分子量和“类药物”结构,具有生物可利用性,可通过 UV-A/405 nm 或相应的近光双光子吸收光活化。 IR (800 nm) 光,导致强大的细胞毒活性,表面上是通过在细胞环境中产生 ROS。多种体外细胞试验证实了 ROS 的形成,而体内细胞毒活性通过以下方式举例说明辐照和随后有针对性地破坏斑马鱼胚胎的特定区域。
