Biological Activity for Flupirtine maleate

Flupirtine maleate is a non-opioid analgesic with muscle relaxant properties. Activates KV7 potassium channels, indirectly antagonizes NMDA receptors and modulates GABAA receptors. Exhibits neuroprotective actions in a model of cerebral ischemia in mice and reduces apoptosis and necrosis induced by noxious stimuli.

Flupirtine maleate effect on liver injury.
By Sadequl Islam on 10/02/2018
Assay Type: In Vivo
Species: Mouse

Used flupirtine to understand how its analgesic effects correlate to its liver injury history. Flupirtine maleate dissloved easily in DMSO and worked nicely in experimental environment The product performed well under study conditions

Flupirtine studied on HEK 293 cell line : Worked ideally on experiemental conditions.
By Farzana Islam on 08/24/2018
Species: Human
Cell Line/Tissue: HEK 293

The Flupirtine maleate worked excellent in study conditions and I would go back to this one everytime I need it. Flupirtine is a non-opioid non-analgesic drug prescribed in some European countries to treat post surgery patients for pain relief. My study involved investigating whether Flupirtine shows BK channel opening properties. Flupirtine works on SK channel and thus it can be speculated that it also works on BK channel to affect neuron excitability. I have used 4 different concentrations of the Flupirtine drug(0.1,1,10 and 100 microgram) to test on HEK 293 cells.NS1619 was used as a standard BK channel opener to compare its channel opening properties.

Dissolve in sterile DMSO under hood if sterile Flupirtine is required.
