Sample solution is provided at 25 µL, 10mM.
Otaplimastat (SP-8203), a matrix metalloproteinase (MMP) inhibitor, blocks N-methyl-D-aspartate (NMDA) receptor-mediated excitotoxicity in a competitive manner. Otaplimastat also exhibits anti-oxidant activity. Otaplimastat can be used for the research of brain ischemic injury[1][2][3].
Otaplimastat (87.5-350 μM; 20 min) protects neuronal cells against NMDA-induced cell death in a competitive manner[1].Otaplimastat (350 μM) inhibits Ca2+ influx following activation of NMDA receptors in primary cultured neuron[1].Otaplimastat (2-200 μM; pretreated for 4 h) significantly suppresses H2O2-induced cell death and reactive oxygen species production[2].
Otaplimastat (10-20 mg/kg; i.p. 30 min before occlusion and 1 h after reperfusion) prevents ischemic neuronal death in the occlusion model of MCA[1].Otaplimastat (5-10 mg/kg; i.p. daily for 10 days) attenuates impairment of stroke-induced motor function[2].

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
