8-Geranyloxypsoralen 是一种呋喃香豆素，分离自葡萄柚，是 P450 3A4 的有效抑制剂(IC50:3.93 μM)。

8-Geranyloxypsoralen inhibits α2-secretase (BACE1) activity in non-competitive manner, with the IC(50) values<25.0 μM, it can induce vasorelaxation on rat arterial tissues. 8-Geranyloxypsoralen possesses nematicidal activities, the median lethal concentrations (LC(50)) is 188.3 mg/ L against B. xylophilus and is 117.5 mg/L against P. redivivus.

Through bioassay-guided fractionations, three coumarins were obtained from the extract of H. candicans and determined to be 8-Geranyloxypsoralen (1), imperatorin (2), and heraclenin (3) based on spectra data. All three compounds possessed nematicidal activities against the two tested nematodes. The median lethal concentrations (LC(50)) of compounds 1-3 at 72 h were 188.3, 161.7, and 114.7 mg L(-1) respectively against B. xylophilus and were 117.5, 179.0, and 148.7 mg L(-1) respectively against P. redivivus[1]
