Biochem/physiol Actions: | 8-methoxypsoralen (8-MOP) plus ultraviolet A (UVA) irradiation induces monoadducts and interstrand cross-links in DNA and therefore can be used to study DNA repair and recombination mechanisms. Cultured normal human melanocytes treated with 8-methoxypsoralen and irradiated with ultraviolet A (UVA) formed 8-methoxypsoralen-phospho |
General description: | Xanthotoxin is an allelochemical or a phototoxic allomone mainly found in host plants of black swallowtail. It can have the tendency to induce tolerance towards Α-cypermethrin, a pyrethroid insecticide used for insects like Helicoverpa zea. |
