(d(CH2)51,Tyr(Me)2,Orn8)-Oxytocin is a cyclic oxytocin analog with a D-amino acid substitution at position 51, methylated tyrosine at position 2, and ornithine at position 8 to enhance receptor selectivity and metabolic stability. This peptide is involved in regulating uterine contractions and lactation. Researchers use it to study the molecular interactions between oxytocin and its receptors, particularly in reproductive physiology.
