Oxytocin antiparallel dimer 

Oxytocin antiparallel dimer is the disulfide-bridged homo peptide dimer. Oxytocin dimer has oxytocin and vasopressin-like activity with less toxic than oxytocin^[1][2].

The parallel and antiparallel homo/hetero bis-cystine dimers of oxytocin and deamino-oxytocin show biological activities ranged from 0.2% to 6% that of oxytocin^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Oxytocin dimer (iv; single dose) shows acute toxicity (LD₅₀=43 mg/kg) is less than that of oxytocin (LD₅₀=25 mg/kg) in rats^[2].
