  • Cyclo(glycyl-L-leucyl) (Cyclo(leu-gly)), a neuropeptide, down-regulates dopamine (DA) receptors and attenuates dopaminergic supersensitivity. Cyclo(glycyl-L-leucyl) inhibits the development of Morphine induced pain relief as well as dopamine receptor supersensitivity in rats. Cyclo(glycyl-L-leucyl) has the potential for the prevention of tardive and/or L-DOPA (HY-N0304)-induced dyskinesias[1][2].

In Vivo Cyclo(glycyl-L-leucyl) (8 mg/kg; 皮下给药) 在阿扑吗啡 (APO) 后 24 小时给予,可减弱由急性高剂量 APO (5 mg/kg; 皮下给药) 引起的 DA 受体超敏反应[1]。 Animal Model: Male Swiss-Webster mice, 20-25g[1] Dosage: 8 mg/kg Administration: SC; single dose given 24h after apomorphine (APO) Result: Attenuated the DA receptor supersensitivity caused by acute high dose APO (5 mg/kg; s.c.).
