galanin (115) (porcine, rat)

Galanin (1-16), mouse, porcine, rat is a hippocampal galanin receptor agonist(Kd = 3 nM) with high biological activity on locus coeruleus neurons.

VIP(6-28)(human, rat, porcine, bovine) acetate is an antagonist of the actions of exogenous vasoactive intestinal peptide (VIP) receptor on cAMP in the superior cervical ganglion (SCG).

ACTH (3-24) (human, bovine, mouse, ovine, porcine, rabbit, rat), the fragment spanning amino acids 3-24 of adrenocorticotropic hormone (ACTH), serves as a research tool in studying a range of illnesses, such as cancer, immune diseases, and cardiovascular disease [1].

(Met(O)27)-Glucagon (1-29) (human, rat, porcine) is a modified version of glucagon that exhibits the same maximum glucose-synthesizing activity in rat hepatocytes as its native counterpart. However, its reduced potency indicates the importance of methionine in glucagon's attachment to hepatic receptors [1].

(Asp28)-Glucagon (1-29) (human, rat, porcine) is an analog of glucagon with an aspartic acid (Asp) substitution at position 28, notably enhancing its aqueous solubility at physiological pH levels while retaining glucagon's innate biological activity [1].

Galanin-Like Peptide (rat), a neuropeptide comprising 60 amino acids, plays a crucial role in regulating feeding, body weight, and energy metabolism [1].

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 (1-16), mouse, porcine, rat is an agonist of the hippocampal galanin receptor, with a Kd of 3 nM. Galanin (1-16), mouse, porcine, rat shows high biological activity on locus coeruleus neurons.

Galanin-Like Peptide (porcine) is a 60 amino acid neuropeptide originally isolated from the porcine hypothalamus. It exhibits a high affinity for the GALR2 receptor with an IC 50 of 0.24 nM and a comparatively lower affinity for the GALR1 receptor, with an IC 50 of 4.3 nM [1].

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.

Peptide YY (13-36) (canine, mouse, porcine, rat) is a Y 2 receptor subtype agonist [1] .

Galanin is a neuropeptide with diverse biological activities. [1][2][3][4][5] It binds to rat galanin (GAL) receptor subtypes GAL1-3 (IC50s = 0.339, 1.35, and 3.31 nM, respectively) and human GAL1-3 (IC50s = 0.288, 1.62, and 12.3 nM, respectively). [1] Galanin binds to and inhibits contraction of guinea pig gastric smooth muscle cells induced by carbachol . [2] In vivo, Galanin (6 nmol, i.c.v.) increases feeding behavior in rats and increases latency to hindpaw withdrawal in response to heat and mechanical stimulation in a rat model of carrageenin-induced inflammation when administered at a dose of 2 nmol injected into the nucleus accumbens.[3][4] Galanin (5 μg, i.c.v.) also inhibits acetylcholine release induced by scopolamine in the ventral hippocampus of freely moving rats. [5]

Proadrenomedullin N-terminal 12 peptide (PAMP-12), an endogenous fragment originating from the adrenal medulla and spanning amino acids 9-20 of human PAMP-20, plays a role in causing hypotension. It functions as an agonist for the MAS-related G protein-coupled receptor family member X2 (MRGPRX2), inhibiting forskolin-stimulated cAMP accumulation in CHO cells expressing human MRGPRX2 (EC50 = 57.2 nM) and selectively prompting calcium mobilization in these cells (EC50 = 41 nM), but not in cells expressing MRGPRX1, MRGPRX3, or MRGPRX4 at 1 µM. As an antagonist of nicotinic acetylcholine receptors (nAChRs), PAMP-12 obstructs carbachol-triggered catecholamine release and the influx of calcium and sodium (IC50s = 1.3, 0.39, and 0.87 µM, respectively) in primary bovine adrenal chromaffin cells, with no effect on histamine-induced responses (IC50s = >1 µM for all). Additionally, it decreases mean arterial blood pressure in normotensive rats at doses ranging from 10 to 50 nmol/kg.

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 (1-29)(rat, mouse) TFA acts as a non-selective agonist for galanin receptors, exhibiting affinities (Kis) of 0.98 nM for GAL1, 1.48 nM for GAL2, and 1.47 nM for GAL3, respectively. It possesses an anticonvulsant effect [1] [2].

VIP(6-28)(human, rat, porcine, bovine) is a potent antagonist that effectively counteracts the effects of exogenous vasoactive intestinal peptide (VIP) on cyclic adenosine monophosphate (cAMP) signaling.
