Description

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.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

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-phospholipid photoadducts that could be substituted for diacylglycerol to activate protein kinase C in a cell-free system. 8-MOP is an inactivator of purified reconstituted cytochrome P450. It also inhibits substance P-induced histamine release from substance P-activated rat peritoneal mast cells by suppressing the rise in [Ca²⁺].

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

This compound is commonly found in plants of the genus: angelica carum pimpinella
