| Description | Protohypericin, a naphthodianthrone derivative found in the plant Hypericum perforatum, exhibits photocytotoxicity and is utilized in tumor necrosis targeted radiotherapy through its radioiodinated form. |
| In vitro | 实验在特定的过滤光条件下进行，以防止Protohypericin的非预期光转换和细胞的光敏化。通过评估照射时间对光细胞性毒性的影响，发现两种化合物的光细胞性毒性在长时间照射后（即15分钟）趋于一致，而在短时间照射（即1分钟）后，光细胞性毒性差异达到最大[1]。 |
