Lipo-oxytocin-1 (LOT-1) is a synthetic peptide and derivative of oxytocin that acts as an agonist of the oxytocin receptor. [1] The lipidation strategy was applied to oxytocin to create a new peptide with improved pharmacokinetics. [1] LOT-1 consists of oxytocin conjugated with two palmitoyl groups. [1] After adjusting for molecular weight (LOT-1 is ~1.5x the weight of oxytocin), oxytocin and LOT-1 are equipotent. [1] In addition, LOT-1 appears to have a significantly longer duration of effect relative to that of oxytocin. [1] It has yet to be determined whether LOT-1 possesses improved blood-brain-barrier permeability relative to oxytocin. [1]
