AdrenocorticotropicHormone (ACTH) (1-39), rat, is a potent melanocortin 2 (MC2) receptor agonist. During in vitro incubation with membrane preparations, peptide fragments of ACTH (1-39) were formed and subsequently isolated by high-pressure methods.
18-Hydroxy-11-deoxy Corticosterone (18-OH-DOC) is a mineralocorticoid produced by the zona fasciculata of the adrenal gland, with its biosynthesis regulated by adrenocorticotropichormone (ACTH) and angiotensin II. This regulation heightens 18-OH-DOC production in isolated human adrenal glomerulosa cells and allows for its formation from 11-deoxy corticosterone (DOC) in human SK-MEL188 melanoma cells. As an intermediate in progesterone metabolism, 18-OH-DOC can be converted to aldosterone in rat adrenal glands' capsular portion. Its continuous infusion (200 μg rat per day) has been shown to raise systolic blood pressure in uninephrectomized saline-drinking rats, and elevated plasma levels of 18-OH-DOC have been observed in the adb db mouse model of type 2 diabetes.
ACTH (1-13) is a 13-amino acid peptide that exhibits cytoprotective effects in a rat model of ethanol-induced gastric lesions. Adrenocorticotropichormone (ACTH), also known as corticotropin, is produced and secreted by the anterior pituitary gland.
