ACTH (11-24) is a fragment of adrenocorticotrophin, induces cortisol release. ACTH (11-24) has been identified as a competitive antagonist of ACTH (1-39) and ACTH (1-10) in isolated adrenal cells.
ACTH (1-13) is a 13-amino acid peptide that exhibits cytoprotective effects in a rat model of ethanol-induced gastric lesions. Adrenocorticotropic hormone (ACTH), also known as corticotropin, is produced and secreted by the anterior pituitary gland.
