Hypocrellin B 是从真菌Hypocrella bambusae和Shiraia bambusicola中分离得到的一种感光颜料，可用于癌症光动力研究。它是一个凋亡诱导剂，还拥有抗菌和抗利什曼活性。

HYPOCRELLIN B are photosensitive pigments isolated from Hypocrella bambusae Sacc. Hypocrellin B causes DNA strand breakage, induces apoptosis in ovarian cancer cells, and inhibits proliferation of Staphylococcus by increasing ROS levels, and damaging cell walls.

Photodynamic therapy with hypocrellin B remarkably induced apoptosis and inhibited adhesion and migration of cancer cells in vitro.

Human ovarian cancer HO-8910 cell as a cancer model cell was incubated with hypocrellin B at a concentration of 2.5 μM for 5 h and irradiated by light from a light-emitting diodes (LED) source. Cell apoptosis was analyzed by flow cytometry with annexin V/propidium iodide (PI) staining and nuclear staining 6 h after hypocrellin B photoirradiation. Cell adhesion was assessed using the 3-(4, 5-dimthylthiazol-2-yl)-2, 5 diphenyl-tetrazolium bromide (MTT) assay 4 h after photodynamic treatment. Cell migration was measured 48 h after photodynamic treatment.
