药理研究
实施例A:对注射了大鼠皮层mRNAs的非洲蟾蜍卵母细胞给予(R,S)-AMPA(10μM)所诱导的电流的抑制
向非洲蟾蜍卵母细胞中注射50ng从大鼠的大脑皮层中分离出的多(A+)mRNAs(poly(A+)mRNAs),并在18℃下孵化2-3天以使蛋白质表达。给予(R,S)-AMPA(10μM)所诱导的流入电流用2电极电压夹的方法(电势=-60mV)在具有下面组分的介质中测定:NaCl(82.5mM),KCl(2.5mM),CaCl2(1mM),MgCl2(1mM),NaH2PO4(1mM),HEPES(5mM),pH7.4。本发明的产物以浓度依赖的方式在给予激动剂(R,S)-AMPA之前30秒和期中给予。
它们对(R,S)-AMPA所诱导的电流的抑制能力通过IC50值(μM)进行测定,IC50值代表抑制给予(R,S)-AMPA(10μM)所诱导的电流50%的浓度。
本发明的化合物显示出色的抑制性IC50值(μM)为1数量级。
实施例B:DBA/2小鼠的音源性惊厥试验
对于未成熟的DBA/2小鼠,可通过将其置于高强度高频率的声音刺激下引发惊厥。AMPA型谷氨酸盐受体拮抗剂对这种惊厥以剂量依赖的方式产生拮抗作用(Chapman等人,Epilepsy Res.,1991,9,92-96)。本试验用于研究本发明化合物的抗惊厥作用。简单来说,将未成熟的DBA/2小鼠(21-28天)暴露在105dB和18kHz的噪音下60秒。这将导致阵挛性惊厥的出现。用于研究的产物和溶剂在试验开始前30分钟以i.p.途径按0.1ml/10g的量给药。对每个化合物的ED50值(抑制50%的惊厥发生的剂量)按照Litchfield和Wicoxon(J.Pharmacol.Exp.Ther.,1949,96,99-113)的方法进行测定。
本发明化合物显示出色的惊厥抑制能力,EC50值在10mg/kg ip.数量级。
实施例C:药物组合物
