メラノスタチン(Melanostatin)は、オキシトシンの切断により生じる内在性ペプチド断片であるが、体内でオキシトシンとは異なる活性を示す[1][2]。Pro-Leu-Gly-NH2の配列のトリペプチドである。Melanocyte-inhibiting factor(MIF-1)とも言う。オピオイド受容体の活性化の影響を阻害する[3][4][5][6][7][8]と同時にドーパミン受容体D2及びD4の正のアロステリック調節因子となり[9][10][11][12][13][14][15][16][17]、またαメラニン細胞刺激ホルモン[18][19][20]等の他の神経ペプチドの放出阻害、メラトニン活性の増強などの活性[21]により、様々な効果を示す。

メラノスタチンの投与は、この複雑な作用の組み合わせによって、抗うつ薬[22][23][24]、スマートドラッグ[25][26][27][28]、抗パーキンソン病薬としての効果を示し[29][30][31]、様々な医療用途で研究が行われている。血中での代謝に耐性を持ち[32]、血液脳関門を容易に通過するが[33][34]、経口では効果が弱く、注射で投与される。重要な作用を持つ、密接に関連した他のペプチドとしては、Tyr-MIF-1やエンドモルフィン-1及び-2等がある[35][36][37][38][39]。
