hypothalamic-pituitary-adrenal axis

ACTH 1-14 acetate(25696-21-3 free base) (Adrenocorticotropic Hormone Fragment 1-14 acetate) is a fragment of adrenocorticotrophin, which regulates cortisol and androgen production.Adrenocorticotropic hormone (ACTH), also known as corticotropin, is produced and secreted by the anterior pituitary gland. ACTH is an important component of the hypothalamic-pituitary-adrenal axis as a response to biological stress.

Exendin-4 (3-39) is a truncated peptide variant of Exendin-4, missing the initial two amino acids, and serves as a potent agonist for the Glucagon-like peptide-1 receptor (GLP-1r). This compound, along with Exendin-4, is utilized in the study of diabetes and hypothalamic-pituitary-adrenal (HPA) axis disorders [1] [2].

Vasopressin (argipressin), a cyclic nine-peptide synthesized by hypothalamic neurons, is one of the hormones involved in peptide prohormone synthesis. Vasopressin is involved in the regulation process of hypothalamic-pituitary-adrenal axis, increasing the amount of solute free water reabsorbed from the renal tubule's colate back into the circulation, narrowing arteries to increase pressure, enhancing the stimulating effect of corticotropin releasing factor to regulate pituitary corticotropin secretion. Vasopressin acts as a neurotransmitter during nerve conduction by binding to specific G-protein-coupled receptors.

ACTH (1-13) is a 13-aa peptide with cytoprotective effects in a model of ethanol-induced gastric lesions in rats. Adrenocorticotropic hormone (ACTH), also known as corticotropin, is produced and secreted by the anterior pituitary gland and plays a critical role in the hypothalamic-pituitary-adrenal axis in response to biological stress.
