Mechanism of Action

Targets/IC₅₀/Ki	PLD2 (Cell-free assay) 20 nM PLD1 (Cell-free assay) 25 nM
In vitro	FIPI inhibits both PLD1 and PLD2 in a dose-dependent manner, with 50% loss of activity observed at approximately 25 nM. This compound efficiently crosses cell membranes and inhibits PLD1 and PLD2 action on their endogenous substrate in the cytoplasmic environment.
In vivo	Mice that receives FIPI at a dose of 3 mg/kg displayes reduced occlusive thrombus formation upon chemical injury of carotid arteries or mesenterial arterioles. Similarly, this compound-treated mice has smaller infarct sizes and significantly better motor and neurological function 24 hours after transient middle cerebral artery occlusion. This protective effect is not associated with major intracerebral hemorrhage or prolonged tail bleeding times.
