Background
Melanocyte stimulating hormone release inhibiting factor,(C13H24N4O3), a tri-peptide with the sequence H2N-Pro-Leu-Gly-amide, MW= 284.35. Melanocyte-inhibiting factor (also known as Pro-Leu-Gly-NH2, Melanostatin, MSH release-inhibiting hormone or MIF-1) is an endogenous peptide fragment derived from cleavage of the hormone oxytocin, but having generally different actions in the body(1). MIF-1 produces multiple effects, both blocking the effects of opioid receptor activation(2), while at the same time acting as a positive allosteric modulator of the D2 and D4 dopamine receptor subtypes, as well as inhibiting release of other neuropeptides such as alpha-MSH, and potentiating melatonin activity(3). MIF-1 is unusually resistant to metabolism in the bloodstream, and crosses the blood–brain barrier easily, though it is poorly active orally and is usually injected.
