DETAILS

Description (English)

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+].

Biochem/physiol Actions
8-甲氧基补骨脂素 (8-MOP) 加 A 波紫外线 (UVA) 辐射可诱导单加合物形成和 DNA 链间交联，因此可用于研究 DNA 修复和重组机制。培养的正常人黑素细胞经 8-甲氧基补骨脂素处理和 A 波紫外线 (UVA) 照射后形成 8-甲氧基补骨脂素-磷脂光加成产物，经二酰甘油取代后可在无细胞体系中激活蛋白激酶 C。8-MOP 是纯化重组细胞色素 P450 的灭活剂。它还可以通过抑制 [Ca2+] 的升高，而抑制从 P 物质激活的大鼠腹膜肥大细胞的 P 物质诱导型组胺释放。
