Sample Use Guides

In Vivo Use Guide

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

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)
