OrphanGPCRSP9155agonistP550 (mouse, rat) (26RFa (mouse, rat)) is an orphanGPCR with an orexigenic effect belonging to the RFamide peptide family. It acts as the cognate ligand for the mouseorphan receptor GPR103, which is also known as SP9155 or AQ27.
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].

Orexin A (Hypocretin-1) (human, rat, mouse) acetate 是一种具有镇痛特性的下丘脑神经肽 (可透过血脑屏障)。Orexin A (human, rat, mouse) acetate 也是一种OX1R 激动剂,能以时间和剂量依赖性的方式诱导 SH-SY5Y 细胞BDNF 和TH 蛋白的表达。Orexin A (human, rat, mouse) acetate 可用于食欲调节、神经退行性疾病,以及调节伤害性信息传递的研究。
Pituitary adenylate cyclase-activating peptide (PACAP) (6-27) is a PACAP receptor antagonist with IC50 values of 1,500, 600, and 300 nM, respectively, for rat PAC1, rat VPAC1, and human VPAC2 recombinant receptors expressed in CHO cells. It binds to PACAP receptors on SH-SY5Y and SK-N-MC human neuroblastoma and T47D human breast cancer cells (IC50s = 24.5, 106, and 105 nM, respectively) and inhibits cAMP accumulation induced by PACAP (1-38) (Kis = 457, 102, and 283 nM, respectively, in SH-SY5Y, SK-N-MC, and T47D cells). In vivo, in newborn pigs, PACAP (6-27) (10 μM) inhibits vasodilation of pial arterioles induced by PACAP (1-27) and PACAP (1-38) . It also inhibits PACAP (1-27)-stimulated increases in plasma insulin and glucagon levels and pancreatic venous blood flow in dogs when administered locally to the pancreas at a dose of 500 μg.
Endogenous agonist at orexin receptors (Ki values are 20 and 38 nM for OX1 and OX2 receptors respectively). Stimulates feeding following central administration and may be involved in the control of sleep-wake cycle and other hypothalamic functions.
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.
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.
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
Galanin (1-16), mouse, porcine, rat is a potent agonist of the hippocampal galanin receptor with a Kd of 3 nM, and it exhibits high biological activity on locus coeruleus neurons.
PACAP-38 (16-38), human, mouse, rat, exhibits potent, efficacious, and sustained stimulatory effects on sympathetic neuronal NPY and catecholamine production.
Orexin A (human, rat, mouse) acetate (205640-90-0 Free base) 是一种 33 个氨基酸的兴奋性神经肽,协调多种中枢和外周过程。 Orexin A (human, rat, mouse) acetate 已用于研究其对猪胰岛功能的影响。 Orexin A (human, rat, mouse) acetate 也被用作食欲素受体 1 (OX1R) 激动剂,以研究食欲素系统对依托孕烯对长期代谢性酸中毒呼吸反应的影响。
