5-methionine-enkephalin amide

[Met5]-Enkephalin, amide is an agonist for δ opioid receptors as well as putative ζ (zeta) opioid receptors. Met-enkephalin circulates in several forms, potentially derived from proteins other than proenkephalin A, and plasma levels of both free native and peptidase-derivable Met-enkephalin are physiologically modulated.

L-Allylglycine is an amino acid derivative that reduces glutamate decarboxylase (GAD) activity by 60% when administered at a dose of 39.8 μmol g per hour ex vivo in mouse brain preparations. L-Allylglycine (1.2 mmol kg, i.p.) induces convulsions and decreases GABA concentration throughout the cerebellum, pons, medulla, striatum, cortex, and hippocampus in mice. Chronic administration (3.2 μg 0.5 μl per hour for 13 days) of L-allylglycine in rats increases locomotor activity in an open field test and impairs attention in the 5-choice serial reaction time task (5CSRTT). In vitro, L-allylglycine inhibits GAD only when used at high concentrations (1-80 mM). The more potent in vivo activity can be attributed to metabolic conversion of L-allylglycine to 2-keto-4-pentanoic acid, a more potent convulsant and GAD inhibitor.

Galantide acetate, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide acetate recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide acetate dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide acetate appears to bind to a single population of SP receptors (KD~40 nM).
