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⁺].
