Amino Acid Sequence

Cys-Tyr-Ile-Gln-Asn-Cys [Disulfide bridge: 1-6]

Application

Tocinoic acid is an oxytocin receptor antagonist and is used to study effects of oxytocin and 5-HT1A receptors on the prosocial effects of 3,4 methylenedioxymethamphetamine (MDMA; ecstasy).[1] It can also be used as a test compound for studying whether the release of protein disulfide isomerase activity is stimulated by activated platelets or not.[2]

Biochem/physiol Actions

Tocinoic acid contains the ring structure of oxytocin that inhibits the release of melanocyte-stimulating hormones (MSH) the rat pituitary in vitro.[3]

Other Notes

N-terminal hexapeptide fragment of oxytocin.
