Uses
A biogenic amine that is the phenol analog of Noradrenaline. It is a neurosecretory product found in several vertebrates and invertebrates. Adrenergic.
Uses
Hypertensive;Adrenergic receptor agonist
Manufacturing Process
A solution of 33 grams of anhydrous aluminum chloride in 60 grams of nitrobenzene, to which a mixture of 14 grams of phenol and 9.3 grams of hydrochloride of amino-acetonitrile was added, had dry hydrochloric acid gas introduced into it for 3 hours, while stirring and cooling to keep the temperature between 20° and 30°C. The reaction mixture was then poured, with cooling, into 70 cc of water and the deposit obtained was sucked off, washed with acetone and dissolved in 300 cc of water. The solution thus prepared was decolorized with carbon, 50 grams of 30% sodium citrate solution was added to it, and then it was made slightly alkaline with ammonia. Thereupon hydroxy-4'-phenyl-1-amino-2-ethanone crystallized out in the form of leaflets. The yield was 7.7 grams.
The hydrochloride of this base, obtained by evaporation to dryness of a solution of the base in dilute hydrochloric acid and subsequent treatment of the residue with ethyl alcohol and acetone, had a chlorine content of 18.84%, (calculated, 18.90%).
This hydrochloride, on being dissolved in water and hydrogenated with hydrogen and a nickel catalyst, gave a good yield of hydrochloride of hydroxy4'-phenyl-1-amino-2-ethanol melting, after crystallization from a mixture of ethyl alcohol and butanone-2, at from 177° to 179°C with decomposition
Therapeutic Function
Hypertensive
General Description
Octopamine is a biogenic amine, which functions as a neurotransmitter, neuromodulator and neurohormone. It is used to regulate various behaviors, such as learning, memory and aggression. Octopamine is present in mammalian tissues, human urine and invertebrates.

Biological Activity
Invertebrate biogenic amine neurotransmitter, related to noradrenalin, that is an adrenoceptor agonist. Stimulates lipolysis in mammalian adipocytes via activation of β 3 receptors. Has dual effect on glucose transport in adipocytes: inhibits transport via β 3 receptor activation but stimulates transport when oxidised by MAO. Also activates human α 2A receptors, inhibiting subsequent cAMP production.
Mode of action
Octopamine hydrochloride is an invertebrate biogenic amine neurotransmitter, related to noradrenalin, that is an adrenoceptor (AR) agonist. Octopamine hydrochloride stimulates lipolysis in mammalian adipocytes via activation of β3-AR receptors. Has dual effect on glucose transport in adipocytes: inhibits transport via β3-AR receptor activation but stimulates transport when oxidised by MAO. Also activates human α2A-AR receptors, inhibiting subsequent cAMP production.
