Orphan GPCR SP9155 agonist P550 (mouse, rat) (26RFa (mouse, rat)) is an orphan GPCR with an orexigenic effect belonging to the RFamide peptide family. It acts as the cognate ligand for the mouse orphan receptor GPR103, which is also known as SP9155 or AQ27.
Brain Natriuretic Peptide (1-32), rat acetate (BNP (1-32), rat acetate) is a 32 amino acid polypeptide hormone synthesized by ventricular cardiomyocytes as a result of myocardial cell stretching (cardiomyocyte distension)[1].
PAR2 (1-6) is a synthetic peptide agonist of proteinase-activated receptor 2 (PAR2) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of mouse and rat PAR2. It also corresponds to residues 39-44 and 37-42 of the mouse and rat full-length sequences, respectively. PAR2 (1-6) induces relaxation in precontracted rat arteries in a concentration-dependent manner, an effect that can be reduced by the nitric oxide synthase inhibitor L-NNA . It inhibits keratinocyte growth in the presence and absence of growth factors. PAR2 (1-6) inhibits LPS-induced pulmonary neutrophil influx and increases in matrix metalloproteinase-2 (MMP-2) activity in mice.
Amyloid-β (25-35) (Aβ (25-35)) is an 11-residue fragment of the Aβ protein that retains the physical and biological characteristics of the full length peptide. It forms fibrils that react to thioflavin T and Congo red and are organized in a cross-β arrangement of β-strands similar to Aβ (1-40) and Aβ (1-42) fibrils. Aggregated Aβ (25-35) decreases the viability of rat adrenal PC12 cells. It also decreases the viability of primary rat cortical neurons at concentrations ranging from 1 nM to 30 μM. In vivo, intracerebral injection of Aβ (25-35) (20 nmol) in rats induces lesions of neuronal and tissue loss. Aggregated Aβ (25-35) administered intracerebroventricularly to rats induces learning and memory impairments in the Y-maze, novel object recognition, and contextual fear conditioning tests.
Non-selective galanin receptor agonist (Ki values are 0.98, 1.48 and 1.47 nM for GAL1, GAL2 and GAL3 respectively). Anticonvulsant; prevents the occurrence of full kindled seizures in rats.
MOG (35-55), human, a constituent of central nervous system myelin, is distinguishable from mMOG (35-55) due to a proline-to-serine substitution at position 42. It possesses immunogenic properties and is partially cross-reactive with mMOG35–55. However, MOG (35-55), human does not induce encephalitogenic effects, and only elicits minimal clinical signs of EAE (experimental autoimmune encephalomyelitis) in comparison to the rodent peptide.
Galanin (2-11) amide is a synthetic peptide fragment of the neuropeptide galanin and an agonist of the galanin-2 (GAL2) receptor (EC50= 9.32 nM in a fluorescence imaging plate reader assay).1It selectively binds to the GAL2receptor (IC50= 1.76 nM for the rat receptor) over the GAL1receptor (IC50= 879 nM for the human receptor) but does also bind to the GAL3receptor (Ki= 271 nM for the rat receptor).1,2Intracerebroventricular administration of galanin (2-11) amide (1 nmol/animal) decreases immobility in the forced swim test in rats.3It also reduces the hind paw mechanical pain threshold and increases the hind paw cold sensitivity threshold in rats.1
Mouse Brain Natriuretic Peptide-45 (BNP-45, mouse) is a circulating variant of the mouse brain natriuretic peptide derived from the mouse heart. It exhibits powerful hypotensive and natriuretic properties.
Brain Natriuretic Peptide (BNP) (1-32), rat is a 32 amino acid polypeptide secreted by the ventricles of the heart in response to excessive stretching of heart muscle cells (cardiomyocytes).Brain natriuretic peptide (type B natriuretic peptide) was origin
Calcitonin Gene Related Peptide II is a potent, long-lasting vasodilator; activation of CGRP receptors on pancreatic β-cells increases plasma levels of pancreatic enzymes.
C-Peptide 2, rat, a 31-amino-acid peptide, serves as a constituent in proinsulin. It possesses the ability to hinder glucose-triggered insulin secretion.
β-Amyloid (1-38), derived from mice and rats, is a chemical compound comprising 38 amino acids, specifically residues 1-38 of the Aβ peptide. Notably, it serves as the primary constituent of amyloid plaques associated with Alzheimer's disease.
β-Amyloid (1-14),mouse,rat is a 1 to 14 fragment of Amyloid-β peptide. β-Amyloid (1-14),mouse,rat is produced through the proteolytic processing of a transmembrane protein, amyloid precursor protein (APP), by β- and γ-secretases. β-Amyloid (1-14),mouse,rat accumulation in the brain is proposed to be an early toxic event in the pathogenesis of Alzheimer’s disease, which is the most common form of dementia associated with plaques and tangles in the brain[1].
