Simufilam (PTI-125) is a low toxicity, orally active filamin A (FLNA) activator. Simufilam preferentially binds altered FLNA and restores its native conformation, restores receptor and synaptic activities, reduces its a7nAChR/TLR4 associations and downstream pathologies. Simufilam can be used for the research of Alzheimer's disease.
