生物活性
Trioxsalen (Trisoralen) 是补骨脂素的衍生物。Trioxsalen 是一种光化学 DNA 交联剂,只有在近紫外线的光激活后才会起作用。Trioxsalen 是一种光敏剂,可用于白癜风和手湿疹的研究。Trioxsalen 可用于激光激活定位的基因组链间交联可视化。
体外研究
Trioxsalen (200 nM) plus 365 nm light produce DNA crosslinks but not breaks in mouse L1210 leukemia cells.
Trioxsalen/UVA treatment of HaCaT keratinocytes induces NFkappaB binding activity, and that this is a synergistic effect.
Trioxsalen shows anti-inflammatory capacities in vitro.
体内研究
Trioxsalen induces dose-dependent depletion of ATPase-positive LCs, with a maximal depletion of 80%, in oral mucous membrane (OMM) with PUVA (UVA doses of 1-8 J/cm2) in rat.
