生物活性 | Flupirtine Maleate is a brain penetrant, and orally bioavailable, non-opioid and centrally acting analgesic agent. Flupirtine Maleate is an indirect N-methyl-D-aspartate receptor (NMDAR) antagonist. Neuroprotective properties[1][2]. |
体外研究 (In Vitro) | Flupirtine (0.1, 1, and 10 mM; 24 hours) significantly reduces the growth and viability of U373 malignant glioma cells with the GI50 of 0.47 mM. Flupirtine has neuroprotective effect of on U373 MG cells[3]. Flupirtine Maleate is active at the KCNQ and GABAA channels in the range of 10-30 μM[4]
Cell Viability Assay[3] Cell Line: | U373 malignant glioma cell lines | Concentration: | 0.001, 0.01, 0.1, 1, and 10 mM | Incubation Time: | 24 hours | Result: | The growth of U373 MG cells was significantly reduced at high doses (1 and 10 mM) of flupirtine compared with low doses (0.001 to 0.1 mM) and control dose. |
|
体内研究 (In Vivo) | Flupirtine (5 and 10 mg/kg) induces acute neuroprotection, reduces motor coordination impairment and ameliorates recombinant tissue plasminogen activator (rtPA)-induced toxicity[2].
Animal Model: | Male C57BL6 mice (22-25 g each)[2] | Dosage: | 1, 5, 10 mg/kg | Administration: | Single intraperitoneal injection during post-ischemic reperfusion | Result: | Both 5 and 10 mg/kg reduced infarct volumes on day 2 post-stroke, no effect was observed with 1 mg/kg. |
