ACTH (7-38) (human) (trifluoroacetate salt)

A peptide fragment of ACTH and an antagonist of MC2R, inhibits ACTH-induced corticosterone production in isolated rat adrenal cells at 0.455 or 4.55 µM, inhibits ACE1 (IC50 = 750 nM for the dog enzyme), inhibits basal cAMP secretion by isolated rat inner adrenocortical cells at 1 µM, induces hypotension in normotensive dogs (ED50 = 0.109 nmol/kg). Formulation: A solid.
