描述 | 5-Methoxypsoralen (Bergapten) is a natural anti-inflammatory and anti-tumor agent isolated from bergamot essential oil, other citrus essential oils and grapefruit juice. 5-methoxypsoralen led to time-dependent as well as dose-dependent inhibitory effects on U-87MG human glioma cells. 5-Methoxypsoralen led to a substantial decrease of cell count along with distorted cell morphology. 5-methoxypsoralen also led to dose-dependent G2/M phase cell cycle arrest. 5-Methoxypsoralen-treated cells also exhibited altered cell ultrastructure with the appearance of autophagic vacuoles and the number of these vacuoles increased with increasing drug dose[3]. 5-MOP (5-Methoxypsoralen) increased the activity of NAT (N-acetyltransferase) and also increased the further metabolism of AAF ( 2-acetylaminofluorene) at 24 h in the rat stomach. 5-MOP decreased the activity of NAT only at 72-h incubation in SC-M1 cells. The optimal concentrations of 5-MOP to induce decreased NAT activity in SC-M1 (human stomach) cells were 0.05 mM to 25 mM. In COLO 205 cells, there is decreased NAT activity at low doses of Bergapten (0.05 mM and 0.5 mM) and increased NAT activity at a high dose (50 mM)[4]. In addition, DSG (diosgenin) and 5-MOP may improve insulin resistance through an ER-mediated PI3K/Akt activation pathway[5]. |
