In Vitro	4-PPBP maleate elicits ERK1/2 phosphorylation in primary neurons[3].
In Vivo	4-PPBP maleate (1 μmol/kg; i.v.) decreases brain injury after transient focal ischemia in rats[2]. Animal Model: Male rats weighing 300 to 385 g (Transient focal ischemia model)[2] Dosage: 1 μmol/kg Administration: Per hour by continuous intravenous infusion starting 1 hour after the initiation of ischemia and continuing through 22 hours of reperfusion. Result: Decreased brain injury after transient focal ischemia in rats.
