Pramiracetam (CAS 68497-62-1) is a small-molecule inhibitor targeting prolyl endopeptidase It is designed to modulate this enzyme thereby influencing neurochemical processes involved in cognitive function Pramiracetam exerts its biological activity primarily through inhibition of prolyl endopeptidase In animal studies pramiracetam demonstrates the ability to modulate cortical nitric oxide synthase (NOS) activity particularly with lithium chloride pretreatment Based on these pharmacological properties pramiracetam holds research potential in the investigation of cognitive impairment following brain injury and in studies of neurodegenerative diseases
