Guanylin (human) TFA is a 15-amino acid peptide that serves as an endogenous activator of intestinal guanylate cyclase. This compound is primarily located in the gastrointestinal tract, where it regulates electrolyte and water transport in the intestinal and renal epithelia through a mechanism dependent on cyclic GMP.

Glucagon-like peptide 1 (1-37), human (TFA), is a highly potent agonist of the GLP-1 receptor and is a pancreatic hormone synthesized through post-translational processing of proglucagon.
Angiotensin II human (Angiotensin II) TFA 作为肾素/血管紧张素系统中关键的生物活性肽,扮演着血管收缩剂的角色并在调节人体血压中发挥中心作用。其主要通过与 G 蛋白偶联受体 (GPCRs)、血管紧张素 II 1型受体 (AT1R) 和血管紧张素 II 2型受体 (AT2R) 的相互作用来介导效应,包括刺激交感神经系统、增加醛固酮的生物合成和肾脏功能。此外,Angiotensin II human TFA 促进血管平滑肌细胞的生长和 I 型及 III 型胶原在成纤维细胞中的合成,导致血管壁与心肌增厚及纤维化,并诱导细胞凋亡。还通过LOX-1依赖的氧化还原敏感路径诱导内皮细胞中的毛细血管形成。
Endogenous peptide activator of intestinal guanylyl cyclase; secreted mainly by the gastrointestinal mucosa. Regulates water and electrolyte transport in intestinal and renal epithelia.
Adrenomedullin (AM) (22-52), human [22-52-Adrenomedullin human], TFA, is a C-terminal truncated analogue of adrenomedullin and acts as an adrenomedullin receptor antagonist.
PACAP (1-38), a novel neuropeptide isolated from the bovine hypothalamus is more active than vasoactive intestinal peptide (VIP) in stimulating adenylate cyclase (EC50=7 nM). PACAP 1-38 (10-9 M) increased substance P (SP), gastrin releasing peptide (GRP),
β-CGRP,human tissue is one of the calcitonin peptide, through complex behavior of calcitonin receptor like receptor (CRLR) - and receptor activity - modifying proteins (increased), and 1 and 300 - nM CRLR IC50s/RAMP1 and CRLR/RAMP2 cells.
