Psoralidin is a furanocoumarin natural product used in Chinese medicine. Psoralidin, a PTP1B inhibitor, has been shown to have anticancer activity with a variety of mechanisms proposed. Psoralidin induces ROS generation in androgen-independent prostate cancer cells, leading to inhibition of cell proliferation. Psoralidin has been found to downregulate NOTCH1 signaling, causing growth arrest in both breast cancer stem cells and breast cancer cells.
Psoralidin is a coumestan derivative extracted from Psoralea corylifolia seeds. It exhibits anti-inflammatory property by inhibiting both cyclooxygenases-2 (COX-2) and 5-lipoxygenase (5-LOX) expression. In addition to its anti-cancer and anti-inflammatory activities, psoralidin also exhibits anti-oxidant, anti-bacterial, and anti-depressant activities. Psoralidin is implicated in the regulation of insulin signaling. It is used as a key ingredient in traditional medicines for bleeding, enuresis, pollakiuria, vitiligo, and psoriasis.
