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.
体外研究
Otaplimastat (87.5-350 μM; 20 min) protects neuronal cells against NMDA-induced cell death in a competitive manner.
Otaplimastat (350 μM) inhibits Ca influx following activation of NMDA receptors in primary cultured neuron.
Otaplimastat (2-200 μM; pretreated for 4 h) significantly suppresses H2O2-induced cell death and reactive oxygen species production.
体内研究
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.
Otaplimastat (5-10 mg/kg; i.p. daily for 10 days) attenuates impairment of stroke-induced motor function.
Animal Model:
Male Wistar rats (280-310 g, 9 weeks) were induced transient middle cerebral artery (MCA) occlusion
Dosage:
10, 20 mg/kg
Administration:
I.p. before 30 min and after an hour of the MCA-occlusion operation
Result:
Significantly reduced infarct volume.
Improved spatial learning and memory impairments.
