The discovery in 1895 of the hypertensive effect of adrenaline (epinephrine) was initiated by Dr Oliver, a physician in practice, who conducted a series of experiments on his young son into whom he injected an extract of bovine suprarenal. The effect was confirmed in animals and led eventually to the isolation and synthesis of adrenaline in the early 1900s. Many related compounds were examined and, in 1910, Barger and Dale invented the word sympathomimetic1 and also pointed out that noradrenaline (norepinephrine) mimicked the action of the sympathetic nervous system more closely than did adrenaline.
Adrenaline, noradrenaline and dopamine are formed in the body and are used in therapeutics. The natural synthetic path is: tyrosine —> dopa —» dopamine —> noradrenaline —> adrenaline.
