Protohypericin 是一种从贯叶连翘中提取的天然石脑粉。放射性碘化 Protohypericin 能用于肿瘤坏死靶向放射研究。

Protohypericin is a naturally occurring naphthodianthrone derived from plant Hypericum perforatum.Radioiodinated protohypericin is used in Tumor necrosis targeted radiotherapy. Protohypericin exhibits photocytotoxicity.

The experimental work was performed in specific filtered light conditions that prevented both an unintended photoconversion of Protohypericin and photosensitization of the cells. Assessing the photocytotoxicity as a function of irradiation time, it was found that the photocytotoxicity of both compounds converged after a long irradiation time (i.e., 15 min), while the difference between the photocytotoxicities was maximal after a short irradiation time (i.e., 1 min)[1]
