 Use of Pro-Leu-Gly-NH2


MIF-1 (Melanostatin), an endogenous brain peptide, is a potent dopamine receptor allosteric modulator. MIF-1 inhibits melanin formation. MIF-1 blocks the effects of opioid receptor activation to modulate the analgesic effects of morphine and stress-induced analgesia (SIA). MIF-1 accesses from the blood to the CNS by directly crossing the blood-brain barrier (BBB)[1][2][3].

In Vitro MIF-1 (Melanostatin, 1 μM) provokes a reversible hyperpolarization and a suppression of spontaneous action potentials[2].
In Vivo MIF-1 (Melanostatin, 1 mg/kg; i.p.; once, for 1 hour; male Wistar rats) modulates the analgesic effects of morphine and stress-induced analgesia (SIA)[1]. MIF-1 (Melanostatin, 1 mg/kg; i.p.; daily, for 8 weeks; Sprague-Dawley rats) attenuates spiroperidol-induced impairment of development of striatal dopamine D2 receptors in rats[3]. Animal Model: Male Wistar rats[1] Dosage: 1 mg/kg Administration: Intraperitoneal injection; once, for 1 hour Result: Decreased the analgesic effect of morphine. Increased the pain threshold for at least 1 h. Animal Model: Sprague-Dawley rats[3] Dosage: 1 mg/kg Administration: Intraperitoneal injection; daily, for 8 weeks Result: Attenuated the ontogenic impairment of striatal D2 receptors that was produced by spiroperidol (HY-B1371) treatment.
