毒理性
Coriamyrtin 在调节中枢神经系统受体时具有抑制活性。换句话说,Coriamyrtin 作为一种在 Anamirta paniculata 和 A. cocculus 中发现的类似毒扁豆碱的倍半萜内酯,具有作为中枢神经系统中强大传递抑制剂的抗惊厥作用模式。在 C-6 位置存在一个羟基,可能对γ-氨基丁酸(GABA)效应器氯通道具有显著的亲和力,是对γ-氨基丁酸效应的拮抗剂,但对丙氨酸或牛磺酸无影响。这些实验是在初级传入末梢上进行的,用于拮抗突触前抑制。毒扁豆碱是所有蛋白质同种型和同源形式中GABA-R和R-Gly的已知拮抗剂。(A15430)
Coriamyrtin has inhibitory activity when modulating receptors of the central nervous system. In other words, coriamyrtin, as a picrotoxin-like sesquiterpene lactones found in Anamirta paniculata and A. cocculus, has a mode of anticonvulsive action as potent transmission inhibitors in the central nervous system. The presence of a hydroxyl group at C-6 could have a significant affinity for a γ-aminobutyric acid (GABA) effector chloride channel, an antagonist to the effects observed on γ-aminobutyric acid but not on alanine or taurine. These experiments were tested on primary afferent terminals and for the antagonism of presynaptic inhibition. Picrotoxin is a known antagonist of GABA-R in all its protein isoforms and R-Gly in the homomeric form. (A15430)
