Lipo-oxytocin-1
Lipo-oxytocin-1 is a synthetic peptide and derivative of oxytocin that acts as an agonist of the oxytocin receptor. The lipidation strategy was applied to oxytocin to create a new peptide with improved pharmacokinetics. LOT-1 consists of oxytocin conjugated with two palmitoyl groups. After adjusting for molecular weight, oxytocin and LOT-1 are equipotent. In addition, LOT-1 appears to have a significantly longer duration of effect relative to that of oxytocin. It has yet to be determined whether LOT-1 possesses improved blood-brain-barrier permeability relative to oxytocin.
