amylin , human

Amylin (8-37), human, derived from human Amylin, possesses direct vasodilator effects in isolated mesenteric resistance arteries of rats. Human Amylin is a small pancreatic β-cell hormone that forms aggregates in the absence of insulin and is a key pathological feature of type II diabetes mellitus.

Amylin (8-37), human acetate(135702-23-7 free base) 源自人 Amylin，对大鼠离体肠系膜阻力动脉具有直接血管舒张作用。 Amylin (8-37), human acetate，是一种小型胰腺 β 细胞激素，在没有胰岛素的情况下会形成聚集体，是 II 型糖尿病的一个关键病理特征。

Amylin, amide, human TFA 是一种含有37个氨基酸的胰腺多肽，与胰岛素共同分泌，对代谢和维持葡萄糖稳态具有重要作用。该化合物能够抑制胰高血糖素的分泌，延缓胃排空速度，同时作为增加饱腹感的因子。

Amylin (8-37) (human) (hIAPP (8-37))，为人类胰岛淀粉样多肽(IAPP)第8至第37位氨基酸片段。该片段在组装过程中形成带有发夹结构的双重折叠构型。

Amylin (1-37) (human) (hIAPP (1-37)) 为胰岛β细胞分泌颗粒中的肽类激素，其C端经酰胺化处理，第2和第7个半胱氨酸残基间形成二硫键。

Acetyl-Amylin (8-37) (human) 是特异性的 amylin 拮抗剂。

Tyr-α-CGRP is an N-terminal extended tyrosinated analogue of α-calcitonin gene-related peptide . It binds to amylin receptors AMY1 and AMY3 in COS-7 cells expressing the human receptors (IC50s = 141 and 1.86 nM, respectively). Tyr-α-CGRP also binds to and stimulates cAMP accumulation in rat L6 myocytes (IC50 = 4 nM; EC50 = 12 nM). It also binds to rat brain and spleen membrane preparations (IC50s = 0.2 and 0.5 nM, respectively), induces positive chronotropic and inotropic effects in isolated right and left guinea pig atria (EC50s = 282 and 74 nM, respectively), and inhibits the twitch response in rat vas deferens (EC50 = 1.9 nM).

Pramlintide is a non-amyloidogenic analog of the antidiabetic peptide hormone amylin that contains proline residues substituted at positions 25, 28, and 29. It stimulates cAMP production in HEK293 cells expressing human amylin receptor 1a (AMY1a), AMY2a, and AMY3a (EC50s = 0.35, 22.9, and 0.89 nM, respectively). Pramlintide inhibits human islet amyloid polypeptide fibrilization in a concentration-dependent manner. In vivo, pramlintide (200 pg/kg) reduces brain levels of amyloid-β (1-40) and increases spontaneous alternation in the Y-maze in the Tg2576 transgenic mouse model of Alzheimer's disease.

Calcitonin is a peptide hormone that lowers blood calcium level and inhibits bone resorption. It belongs to the calcitonin family of peptides, which also includes amylin , calcitonin gene-related peptide , and adrenomedullin. The binding of salmon calcitonin to the human calcitonin receptor (CTR) is not modulated by receptor activity-modifying proteins (RAMPs), which influence affinity of human calcitonin to CTR. Salmon calcitonin binds to human CTR2 with IC50 values of 0.933, 0.224, 0.134, and 0.317 nM alone and with RAMP1, 2, or 3, respectively. It induces cAMP accumulation in COS-7 cells transfected with CTR2 (EC50 = 0.166 nM). Salmon calcitonin inhibits bone resorption by osteoclasts in a pit formation assay using rat bone slices (ID50 = 0.003 pg mL) and lowers calcium level in vivo in a bioassay of hypocalcemia in rats (ED15 = 33.9 mg kg). Formulations containing salmon calcitonin have been used to treat hypercalcemia, bone destruction by osteoporosis, and Paget's disease.

Pramlintide, a polypeptide analog of human amylin, is an antidiabetic agent with antineoplastic properties in colorectal cancer.

Pramlintide TFA，一种人类淀粉样肽类似物，主要作为抗糖尿病药物使用，并可用于肠癌研究。

Amylin (1-37), human acetate(hIAPP (1-37), acetate)是由胰腺与胰岛素共同分泌的一种含有37个氨基酸的肽激素，在葡萄糖稳态中抑制胰高血糖素分泌和产生饱腹感，是2型糖尿病患者胰腺中淀粉样蛋白沉积的主要成分。

NF(N-Me)GA(N-Me)IL是一种改性的生物活性肽，对应于人胰岛淀粉样蛋白多肽hIAPP中的22至27氨基酸片段（NFGAIL），其G24和I26的酰胺键经N-甲基化处理。引入N-甲基基团使得原本促进淀粉样蛋白形成及具细胞毒性的序列变为不促进淀粉样蛋白形成和无细胞毒性。此肽可高亲和力结合至全长hIAPP，并有效抑制其纤维化过程。

Amylin, amide, human是一种由37个氨基酸组成的多肽激素，与胰岛素共分泌，参与调节餐后血糖水平,通过抑制胰高血糖素分泌、延缓胃排空等方式降低血糖。DAP Amylin在溶液中不稳定，易聚集形成淀粉样纤维，与2型糖尿病的胰岛β细胞损伤密切相关。

Pramlintide acetate是人源淀粉样肽的多肽类似物。作为一种抗糖尿病药物，它在结直肠癌中展现出抗肿瘤活性。
