Otaplimastat

(Synonyms: SP-8203)

Revisión del cliente

Based on 1 Customer Validation

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.

In Vitro

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Male Wistar rats (280-310 g, 9 weeks) were induced transient middle cerebral artery (MCA) occlusion^[1]
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.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
