毒理性
抑制昆虫细胞色素P450(L579)。许多呋喃香豆素的作用机制基于它们与DNA和其他细胞组分(如RNA、蛋白质以及膜中的一些蛋白质,如磷脂酶A2和C、依赖Ca和cAMP的蛋白激酶和表皮生长因子)形成光加合物的能力。呋喃香豆素在DNA的碱基对之间插入,并在紫外线A照射后给出环加合物(L579)。
Inhibits insect cytochrome P450 (L579). The mechanism of action many furocoumarins is based on their ability to form photoadducts with DNA and other cellular components such as RNA, proteins, and several proteins found in the membrane such as phospholipases A2 and C, Ca-dependent and cAMPdependent protein-kinase and epidermal growth factor. Furocoumarins intercalate between base pairs of DNA and after ultraviolet-A irradiation, giving cycloadducts. (L579).
