galanin , human

Galanin (1-30), human acetate (Galanin ) 是一种 30 个氨基酸的神经肽。 它是 GalR1 和 GalR2 受体的激动剂，Kis 均为 1 nM。

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-Like Peptide (human) 是由60个氨基酸组成的神经肽，在调节摄食、体重和能量代谢方面具有重要功能。

Galanin (1-19), human, represents the fragment encompassing amino acids 1 to 19 of the human galanin neuropeptide. Galanin (GAL) is known for its extensive distribution and multifaceted biological roles, such as regulating hormone secretion, providing antinociceptive effects, and altering feeding behavior.

Galanin (Human) (Acetate)是一种含有30个氨基酸的神经肽和丙氨酸(GAL)受体激动剂。在表达重组人gal1受体的HEK293E 细胞(EC50= 0.031 nM)中，它抑制佛司可林诱导的cAMP 产生，并刺激表达重组人gal2受体的CHO 细胞(EC50= 12.3 nM)中肌醇磷酸的积累。Galanin (Human) (Acetate)诱导离体大鼠纵向眼底收缩，ec50值为13.8 nM。在大鼠福尔马林试验的第二阶段，鞘内给药人甘丙肽(3、10和30 nmol/只)可减少大鼠舔爪和退缩。

Galanin (1-30), human, is a 30-amino acid neuropeptide that acts as an agonist of GalR1 and GalR2 receptors with Kis of 1 nM. This endogenous peptide exhibits multiple endocrine, metabolic, and behavioral effects and has demonstrated activity on the intestinal system.

Alarin (human) 属于下丘脑甘丙肽家族，包含 GALP 前体肽的信号序列和成熟 GALP 前 5 个氨基酸。

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.

Human GALP (3-32) (Galanin-like peptide (3-32)) 是一种高效的galanin receptor激动剂。在竞争性结合实验中，该化合物对GalR1 (IC50=33 nM) 及GalR2 (IC50=15 nM) 表现出强烈亲和力。此外，human GALP (3-32) 显著增加了转染GalR2 (EC50=360 nM) 的 SH-SY5Y细胞的胞外酸化速率。
