139corticotropin (human)(tfa)

Adrenocorticotropic Hormone (ACTH) (1-39) human (TFA), a member of the melanocortin family, is a melanocortin receptor agonist that stimulates corticosteroid production by the adrenals; melanocortin receptors are also located in the central nervous system (CNS) and on immune cells.

Adrenocorticotropic Hormone (ACTH) (1-39), rat (TFA), is a potent agonist of the melanocortin 2 receptor (MC2).

The big endothelins comprise residues 53-90 (human big ET-1) and 53-91 (porcine big ET-1) of the endothelin precursor (preproendothelin). Compared to the mature endothelin-1 (ET-1), both peptides show less vasoconstrictor activity in vitro, but similar pressor effects in vivo. Former CAS-number 121014-54-8.

Osteostatin (human), a fragment derived from parathyroid hormone-related protein (PTHrP) 107-139, effectively promotes bone repair in animal models with bone defects and inhibits bone erosion in cases of inflammatory arthritis [1].

PLP (178-191), an immunodominant encephalitogenic epitope from the proteolipid protein (PLP) fragment spanning amino acids 178 to 191, plays a pivotal role in SJL mice. It initiates disease onset earlier compared to the other major encephalitogenic epitope, PLP (139-151), though both epitopes result in similar incidence, severity, and histologic characteristics.

J5 peptide, an MBP inhibitor, competitively inhibits the binding of MBP 85-99 to HLA-DR2, and mitigates PLP 139-151 MBP 85-99-induced experimental autoimmune encephalomyelitis (EAE) in mice. It is utilized in research pertaining to inflammatory and immune diseases [1].

Adrenocorticotropic Hormone (ACTH) (1-39), human, is an agonist of the melanocortin receptor.

[Leu144,Arg147]-PLP (139-151) is a mutated fragment of the myelin proteolipid protein (PLP), featuring substitutions of tryptophan to leucine and histidine to arginine at positions 144 and 147, respectively. Immunizing mice with this peptide (50 µg) mixed in complete Freund's adjuvant (CFA) elevates IL-4 levels in the spleen. While it suppresses Th1 cell activation in vitro, it does not do so in vivo; instead, it promotes the development of regulatory T cells. Preimmunization with [Leu144, Arg147]-PLP (139-151) postpones the onset of experimental autoimmune encephalomyelitis (EAE) triggered by encephalitogenic peptides from PLP (178-191), myelin oligodendrocyte glycoprotein (MOG) (92-106), or myelin basic protein (MBP) in mice.

Adrenocorticotropic Hormone (ACTH) (1-39), rat, is a potent melanocortin 2 (MC2) receptor agonist. Peptide fragments of ACTH (1-39) were formed during in vitro incubation with membrane preparations, isolated by high-pressure liquid chromatography, and characterized by determining their amino acid composition and NH2-terminal residue.

PLP (139-151), an amino acid residue from positions 139 to 151 of myelin proteolipid protein (PLP), is utilized to induce the relapsing-remitting (RR)-EAE model.

[SER140]-PLP(139-151) is a polypeptide fragment derived from the myelin-associated lipid protein.

[SER140]-PLP(139-151) acetate is a peptide fragment from myelin proteolipid protein (PLP).

[SER140]-PLP(139-151) (TFA) is a polypeptide fragment of the myelin lipid protein.

Endogenous truncated form of the incretin hormone GIP. More potent at stimulating glucose-dependent insulin secretion from rat pancreatic β-cells than GIP.

GIP (1-39) acetate is a gastric inhibitory peptide (GIP) purified from porcine intestine and stimulates insulin secretion.

MAPI is an irreversible peptidyl 3C cysteine protease (SV3CP) inhibitor. By covalently attaching its C-terminal Michael acceptor moiety to the active site thiol of SV3CP Cys 139, MAPI inhibits SV3CP. It shows potential for use in the study of norovirus infections.
