在过去的几年里，光毒性已经在分子水平上进行了研究，这些研究为DNA损伤表征、DNA修复和细胞对紫外线诱导的应激反应等领域提供了新的见解。随着新型抗生素和抗炎药物的发展，在新化合物安全性评价中开展光毒性评价的必要性日益突出。本文综述了细胞对紫外线胁迫反应的已知分子机制、可提出和用于筛选阳光毒性的体外方法以及光活化药物引起的光敏过程。列出了该特定目标的紫外线源、生物系统和感兴趣的端点。光毒性作用从细胞毒性-凋亡效应到诱导DNA初级损伤、DNA修复和多种应激基因作用于细胞周期和细胞命运。最终，它可能导致遗传DNA修饰的诱导。提出了各种各样的测定方法来专门解决紫外线诱导毒性的所有这些特殊后果。
During the past several years, phototoxicity has been studied at the molecular level, and these studies have provided new insights in the field of DNA lesion characterization, DNA repair and cell response to ultraviolet (UV)‐induced stress. The development of new antibiotics and antiinflammatory drugs has highlighted the necessity to develop the assessment of phototoxicity in the safety evaluation of new chemical compounds. This paper aims at reviewing the known molecular mechanisms of the cellular response to UV‐induced stress, the in vitro methods that can be proposed and used to screen for toxicity of sunlight and the photosensitization process resulting from the activation of drugs by light. UV sources, biological systems and endpoints of interest in that particular objective are listed. Phototoxic effects span from the cytotoxic–apoptotic effect to the induction of primary DNA damage, DNA repair and a variety of stress genes acting on the cell cycle and the fate of the cell. Ultimately, it can lead to the induction of hereditary DNA modification. A variety of assays are proposed to specifically address all these particular consequences of UV‐induced toxicity.
