[体外研究]

洛美利嗪是L-和T-型电压控制钙通道和瞬时受体电位通道5瞬时受体电位通道的拮抗剂。洛美利嗪是一种双L/T型通道阻滞剂,用于预防偏头痛。为了证明洛美利嗪在限制细胞内[Ca2 +]中的有效性,评估了其抑制谷氨酸诱导的运动神经元死亡的能力以及细胞溶质[Ca2 +]的相关升高。洛美利嗪抑制分离浓度为0.01μM的解离大鼠脑神经元中的低电压和高电压激活的Ca2 +电流,并且1μM洛美利嗪抑制海马神经元中IC50为1.9μM和H2O2诱导的Ca2 +内流。用1μM洛美利嗪预处理可显着降低暴露于50μM谷氨酸的脊髓-DRG培养物中运动神经元的急性死亡,该浓度在培养6小时后杀死大约40％的运动神经元,并抑制细胞溶质的增加[用谷氨酸处理发生的Ca2 +]。 0.5μM洛美利嗪足以显着预防SOD1G93A诱导的线粒体线粒体断裂[1]。洛美利嗪增加阿霉素(ADM)的细胞毒性和ADM或长春新碱(VCR)诱导的K562/ADM细胞凋亡。洛美利嗪浓度为3,10和30μM时,ADM的IC50值分别从79.03μM降至28.14,8.16和3.16μM。洛美利嗪增加ADM的细胞内积累并抑制Rh123在K562/ADM细胞中的流出。在洛美利嗪处理72小时后未观察到P-gp表达的变化。洛美利嗪通过抑制P-gp功能对K562/ADM细胞的MDR具有强烈的逆转作用[2]。

[体内研究]

为了确定Ca2 +信号分子是否在p50缺陷小鼠中介导NMDA诱导的神经毒性,检查化学试剂的神经保护作用,其作用于Ca2 +信号通路,包括CaN活化,对NMDA诱导的RGC死亡。 2个月龄的p50缺陷小鼠显示正常的RGC存活率,用NMDA拮抗剂MK801或美金刚进行腹膜内预处理;钙阻滞剂,洛美利嗪;和KN抑制剂他克莫司每天注射5nM NMDA前1周。洛美利嗪或他克莫司长期给予KO小鼠6个月导致存活的RGC数量增加(p <0.0001)[3]。洛美利嗪(KB-2796; 0.3和1mg/kg,iv)在给药后分别在30分钟和15分钟时剂量依赖性地增加脑血流量。洛美利嗪(1 mg/kg,iv)显着减弱同侧额顶皮质中c-Fos样免疫反应的表达[4]。

[细胞实验]

MTT法用于测定洛美利嗪对阿霉素（ADM）细胞毒性的影响。采用流式细胞仪检测洛美利嗪（3,10和30μM）对ADM和长春新碱（VCR）诱导的K562 / ADM细胞凋亡的影响。通过荧光分光光度法测量ADM的细胞内积累。流式细胞术用于研究罗丹明123（Rh123）的外排和P-糖蛋白（P-gp）在K562 / ADM细胞中的表达[2]。

[动物实验]

小鼠[3]每天2个月的p50缺陷小鼠和野生型小鼠腹膜内预处理美金刚（10 mg / kg），MK-801（0.5 mg / kg），洛美利嗪（1 mg / kg），在NMDA注射前一周，或他克莫司（2,0.5和0.2mg / kg）一周。给这些小鼠玻璃体内注射5nM NMDA，这是引起神经毒性的相对低浓度[3]。大鼠[4]将体重为250-350g的雄性Wistar大鼠圈养在25±0℃，55±5％湿度的空调房间中，随意给予食物和水。洛美利嗪以1mL / kg体重的体积静脉内注射。洛美利嗪（0.3 mg / kg，静脉注射或1 mg / kg，静脉注射）的效果测量是通过激光多普勒血流仪（CBFLDF）测量的麻醉大鼠的大脑皮层血流量[4]。
