Sample Use Guides

Intravenous Minopafant administration (300 ug or 1200 ug twice daily) was begun within 4 days and continued for 14 days.
Route of Administration: Intravenous
In Vitro Use Guide
Curator's Comment: The cultured neurons were exposed to glutamate (1 mM) for 60 min. Twenty-four hours after this exposure, protective effect of E5880 against neuronal damage was tested.
Minopafant (E5880) was tested for its neuroprotective activity in primary neuronal cultures isolated from embryonic rat cerebral cortex. Protective effect was observed in cultures treated with E5880 (P < 0.01 at 10 nM E5880)
