cerebral protective effect. Among these, compound 2 exhibited a cerebral protective effect through suppressing neuronal hyperexcitability due to an increase in the excitatory neurotransmitter glutamic acid. Furthermore, compound 2 did not affect heart rate and mean systolic blood pressure. This investigation suggests that compound 2 has potential for further development as a cerebral protective drug.
已经将脑保护药物作为痴呆的潜在疗法给予了相当大的关注。筛选天然化合物库在这里导致鉴定出五个坎西酮生物碱,即,苦参碱L(1),苦参碱O(2),杜鹃花碱E(3),3-乙基-canthin-5,6-dione(4) ,和3-乙基-4-甲氧基-canthin-5,6-dione(5),作为新型的脑保护剂。构效关系表明,C-4,C-9和N-3取代极大地影响了它们的脑保护作用。其中,化合物2通过抑制由于兴奋性神经递质谷氨酸的增加而引起的神经元过度兴奋而表现出对大脑的保护作用。此外,化合物2不会影响心率和平均收缩压。这项研究表明,化合物2作为脑保护药物具有进一步开发的潜力。
