[des-tyr1]-met-enkephalin

Enkephalin-met, des-tyr(1)- ccauses retrograde amnesia in rats.

'(Des-Bromo)-Neuropeptide B (1-23) (human)' is an agonist for orphan G-protein-coupled receptors, exhibiting a K i of 1.2 nM for GPR7 (NPBW1) and 341 nM for GPR8 (NPBW2) respectively [1].

(Met(O)27)-Glucagon (1-29) (human, rat, porcine) is a modified version of glucagon that exhibits the same maximum glucose-synthesizing activity in rat hepatocytes as its native counterpart. However, its reduced potency indicates the importance of methionine in glucagon's attachment to hepatic receptors [1].

(Des-Glu5)-ACTH (1-24) (human, bovine, rat) is an adrenocorticotropic hormone (ACTH) analogue, synthesized by the anterior pituitary gland to regulate cortisol and androgen production [1]. This polypeptide tropic hormone variant differs from ACTH by the absence of glutamic acid at the fifth position.

Alexamorelin Met 1 is one of the metabolites of alexamorelin. The heptapeptide Ala-His-D-2-methyl-Trp-Ala-Trp-D-Phe-Lys-NH2 (Alexamorelin) is a synthetic molecule which inhibits growth hormone secretagogue binding in vitro.

(D(CH2)51,Tyr(Me)2,Thr4,Orn8,des-Gly-NH29)-Vasotocin, serving as an oxytocin receptor antagonist, effectively nullifies the augmentation of inhibitory postsynaptic currents in CA1 pyramidal neurons by oxytocin [1].

(Met(O2)35)-Amyloid β-Protein (1-42) is a peptide [1] .

(Met(O)35)-Amyloid β-Protein (1-42) represents the oxidized form of Methionine 35 in Aβ42, capable of producing an oligomer size distribution akin to that of Aβ40. This compound is utilized in Alzheimer’s disease (AD) research [1].

(Des-His^6)-ACTH (1-24) (human, bovine, rat) is an adrenocorticotropic hormone (ACTH) analog. Produced by the anterior pituitary gland, ACTH is a polypeptide tropic hormone that regulates the production of cortisol and androgens [1].

Tyr-Gly-Gly-Phe-Met-OH (Met-Enkephalin), is a naturally occurring, endogenous opioid peptide that inhibits tumor growth via binding to the opioid receptor.

(Phenylac1,D-Tyr(Et)2,Lys6,Arg8,des-Gly9)-Vasopressin, a potent vasopressin V1 receptor (VP V1R) antagonist, significantly lowers mean arterial pressure (MAP) in rats [1].

Tyr-W-MIF-1, an opioid tetrapeptide, exhibits both opiate and antiopiate activities, and has been demonstrated to induce analgesia [1] [2] [5].

Enkephalin-met, ala(2)- is a synthetic analog of methionine enkephalin.
