Biological Activity:
DL-Adrenaline is a hormone and a neurotransmitter secreted by the medulla of the adrenal glands. In medicine DL-Adrenaline is used chiefly as a stimulant in cardiac arrest, as a vasoconstrictor in shock, and as a bronchodilator and antispasmodic in bronchial asthma. DL-Adrenaline is found in small amounts in the body and is essential for maintaining cardiovascular homeostasis because of its ability to divert blood to tissues under stress. DL-Adrenaline acts by binding to a variety of adrenergic receptors. DL-Adrenaline is a nonselective agonist of all adrenergic receptors, including α1, α2, β1, β2, and β3 receptors. Epinephrine’s binding to these receptors triggers a number of metabolic changes. Binding to α-adrenergic receptors inhibits insulin secretion by the pancreas, stimulates glycogenolysis in the liver and muscle, and stimulates glycolysis in muscle.
