Any peptide with hormonal activity in animals, whether endocrine, neuroendocrine, or paracrine.
| Member | Definition | Role |
|---|
| alpha-msh | A thirteen amino acid peptide hormone consisting of N-acetyl-L-Ser, L-Tyr, L-Ser, L-Met, L-Glu, L-His, L-Phe, L-Arg, L-Trp, Gly, L-Lys, L-Pro and L-valinamide units joined in sequence by peptide linkages. It is an endogenous melanocortin receptor agonist that exhibits anti-inflammatory activity. | alpha-melanocyte stimulating hormone |
| bradykinin, hydroxy-pro(3)- | An oligopeptide that is an analogue of bradykinin in which the third amino acid, proline, is replaced with hydroxyproline. | [Hyp(3)]-bradykinin |
| glucagon | A 29-amino acid peptide hormone consisting of His, Ser, Gln, Gly, Thr, Phe, Thr, Ser, Asp, Tyr, Ser, Lys, Tyr, Leu, Asp, Ser, Arg, Arg, Ala, Gln, Asp, Phe, Val, Gln, Trp, Leu, Met, Asn and Thr residues joined in sequence. | glucagon |
| gonadotropin-releasing hormone | A ten-membered synthetic oligopeptide comprising pyroglutamyl, histidyl, tryptophyl, seryl, tyrosyl, glycyl, leucyl, arginyl, prolyl and glycinamide residues joined in sequence. | gonadorelin |
| neurotensin | A 13 amino acid peptide hormone which is found in the central nervous system and the gastrointestinal tract. It behaves as a neurotransmitter in the brain, as a hormone in the gut, and also as a neuromodulator. It is implicated in the pathophysiology of several CNS disorders (including schizophrenia, Parkinson's disease, drug abuse, pain, cancer, inflammation, eating disorders and central control of blood pressure) due to its association with a wide variety of neurotransmitter systems such as dopaminergic, sertonergic, glutamatergic, GABAergic, and cholinergic systems. | neurotensin |
| oxytocin | A cyclic nonapeptide hormone with amino acid sequence CYIQNCPLG that also acts as a neurotransmitter in the brain; the principal uterine-contracting and milk-ejecting hormone of the posterior pituitary. Together with the neuropeptide vasopressin, it is believed to influence social cognition and behaviour. | oxytocin |
| pasireotide | A six-membered homodetic cyclic peptide composed from L-phenylglycyl, D-tryptophyl, L-lysyl, O-benzyl-L-tyrosyl, L-phenylalanyl and modified L-hydroxyproline residues joined in sequence. A somatostatin analogue with pharmacologic properties mimicking those of the natural hormone somatostatin; used (as its diaspartate salt) for treatment of Cushing's disease. | pasireotide |
| prosomatostatin | A heterodetic cyclic peptide consisting of somatostatin in which the amino terminus has been acylated by the fourteen membered peptide Ser-Ala-Asn-Ser-Asn-Pro-Ala-Met-Ala-Pro-Arg-Glu-Arg-Lys. | somatostatin-28 |
| salmon calcitonin | A 32-membered heterodetic cyclic peptide comprising the sequence Cys-Ser-Asn-Leu-Ser-Thr-Cys-Val-Leu-Gly-Lys-Leu-Ser-Gln-Glu-Leu-His-Lys-Leu-Gln-Thr-Tyr-Pro-Arg-Thr-Asn-Thr-Gly-Ser-Gly-Thr-Pro-NH2 cyclised by a disulfide bridge between the two Cys residues at positions 1 and 7. | calcitonin |
| somatostatin | A fourteen-membered heterodetic cyclic peptide comprising the sequence Ala-Gly-Cys-Lys-Asn-Phe-Phe-Trp-Lys-Thr-Phe-Thr-Ser-Cys cyclised by a disulfide bridge between the two Cys residues at positions 3 and 14. | somatostatin |
| thyrotropin-releasing hormone | A tripeptide composed of L-pyroglutamyl, L-histidyl and L-prolinamide residues joined in sequence. | protirelin |
