nonapeptide-1

Nonapeptide-1 (Melanostatine™ 5) can inhibit the synthesis of melanin, which makes it of interest for treating certain skin conditions.

Nonapeptide-1 (Melanostatine-5) acetate salt is a peptide hormone that functions as a selective and competitive antagonist of the melanocortin 1 receptor (MC1R) with a binding affinity (K i) of 40 nM. It effectively inhibits α-MSH-induced increases in intracellular cyclic AMP (cAMP) and melanosome dispersion in melanocytes, with inhibitory concentrations (IC 50) of 2.5 nM and 11 nM, respectively. By inhibiting melanin synthesis, Nonapeptide-1 acetate salt is used in research related to skin pigmentation, adrenal gland steroid production regulation, and skin cancer [1] [2] [3].

Nonapeptide-1 acetate salt (158563-45-2 free base) (Melanostatine-5 acetate salt) , a peptide hormone, is a potent α-Melanocyte-stimulating hormone (α-MSH) antagonist, with an IC50 of 11 nM. Nonapeptide-1 acetate salt (158563-45-2 free base) , a peptide hormone, is a potent α-Melanocyte-stimulating hormone (α-MSH) antagonist, with an IC50 of 11 nM.

GLP-1(28-36)amide, a C-terminal nonapeptide derived from the cleavage of GLP-1 by neutral endopeptidase (NEP), is an important compound that functions as an antioxidant primarily targeting the mitochondrion to inhibit mitochondrial permeability transition (MPT), displaying anti-diabetic properties and cardioprotection effects[1].

Hemopressin(rat) TFA, a nonapeptide originating from the α1-chain of hemoglobin, was first isolated from rat brain homogenates. It acts as an orally active, selective, and inverse agonist of the CB1 cannabinoid receptors and demonstrates antinociceptive effects in models of inflammatory pain [1] [2].

CooP, a linear glioblastoma-targeting nonapeptide, interacts with the mammary-derived growth inhibitor/fatty acid binding protein 3 (FABP3) found in glioblastoma cells and their associated blood vessels. This interaction facilitates the targeted delivery of chemotherapy and various nanoparticles [1].

TCMCB07, a cyclic nonapeptide, serves as an orally active, brain-penetrant antagonist of the melanocortin receptor 4 (MC4R), with significant implications in the management of cachexia [1].

TCMCB07 TFA is a cyclic nonapeptide and an orally active, brain-penetrating antagonist of the melanocortin receptor 4 (MC4R), playing a significant role in managing cachexia [1].

Tyrosinase (192-200), a human mouse nonapeptide, is recognizable by cytolytic T cells (CTL) on the HLA-B44 molecule and is utilized in the research of melanoma-associated cancers [1].

TPNQRQNVC, a nonapeptide epitope of HLA-B0702, induces a CD8+ T cell immune response [1].

Chemerin-9 (149-157) TFA is a peptide located at positions 149-157 of chemerin-9, retaining most of the activity of the full protein. Chemerin-9 acts as a ChemR23/CMKLR1 agonist, preventing atherosclerosis whilst inhibiting NLRP3 inflammasome activation and promoting Aβ microglial clearance. It modulates blood pressure and sympathetic nervous system activity via glutamate receptor-mediated ROS production.

p5 Ligand for Dnak and DnaJ acetate is a nonapeptide. It is a high-affinity ligand for DnaK (E. coli Hsp70) and DnaJ (E. coli Hsp40).

Substance P (1-9) is a nonapeptide that reduces the inactivation of substance P in the guinea-pig ileum and urinary bladder, and is responsible for various excitatory effects on central and peripheral neurons.

Substance P 1-9 aceate is nonapeptide, which decreases the inactivation of substance P by the guinea-pig ileum and urinary bladder.
