WebJun 30, 2024 · For the first time, the dark and red-light-induced cytotoxicity of these photocaged compounds could be tested under hypoxia (1 % O 2). In skin (A431) and lung (A549) cancer cells, a 3- to 4-fold increase in cytotoxicity was found upon red-light irradiation for [2]Cl 2, whether the cells were cultured and irradiated with 1 % or 21 % O 2. These ... Web2.3.3.3 Storage and handling of photocaged dimerizers. Care should be taken when working with photocaged compounds, strong ambient light (e.g., from brightfield microscopy) has been reported to remove coumarin photocages. Care was taken to minimize exposure of dimerizers to light and heat prior to experiments. In our hands, working quickly in ...
