GENERAL
DESCRIPTION & APPLICATIONS
|
Ephedrine is a sympathomimetic alkaloid originally obtained from species of
Ephedra or prepared synthetically. Its action is similar to that of epinephrine
(a catecholamine hormone secreted by the adrenal medulla and a
neurotransmitter). Its effects, although less powerful, are more prolonged, and
it exerts action when administered orally, whereas epinephrine is effective only
by injection. It is used as muscle relaxants, central nervous system and cardiac
muscle stimulants in combination with others like theophylline. It is used to
prevent hypotension during spinal and infiltration anesthesia; and as a
mydriatic. There are enantiomers in ephedrine structure. (1R,2S)- and
(1S,2R)-enantiomers are designated ephedrine (opposite stereoisomerisms around
the chiral center), whereas (1R,2R)- and (1S,2S)-enantiomers are designated
pseudoephedrine. Commercial ephedrine is (-)-(1R,2S)-ephedrine [also called
(-)-Ephedrine or L-ephedrine], while commercial pseudoephedrine enantiomer is
(1S,2S)-pseudoephedrine [(+)-pseudoephedrine or D-pseudoephedrine].
Pseudoephedrine has less pressor action and fewer central stimulant effects than
ephedrine. Pseudoephedrine is used as a nasal decongestant and a bronchodilator
to relaxe and open the air passages to the lung to increase the flow of air, and
thus is used in the treatment and/or prevention of symptoms of bronchial asthma
and of reversible bronchospasm associated with chronic bronchitis and emphysema.

GENERAL
DESCRIPTION OF TYRAMINE & TRYPTAMINE |
Tyramine
[4-(2-Aminoethyl)phenol] is a monoamine compound of 4-hydroxy phenethylamine. It
is derived from tyrosine, an amino acid (protein building block) that is the
precursor of norepinephrine. It, through its effect on neurotransmitters, may
affect several health conditions, including Parkinson's disease, depression,
alcohol withdrawal support, and Phenylketonuria. (PKU). Tyramine is naturally
found in plant and animal tissues, certain cheeses and ergot or produced
synthetically. It is metabolized by monoamine oxidase. Tyramine or its
derivatives can be used in pharmaceutical industry such as:
- Sympathomimetic or adrenergic drugs themselves or
intermediate of them.
- Intermediate
for bezafibrate used in the treatment of high cholesterol levels.
- Determination of peroxide activity in the
fluorescence enzyme immunoassay for insulin.
- False
transmitter.
Tryptamine
[3-(2-Aminoethyl)indole] is a biologically important monoamine compound derived
by the decarboxylation of tryptophan, indole side chain amino acid. In addition
to its function to build the structure of protein, tryptophan is a precursor for
neurotransmitter and neurohormone. Tryptamine (biological monoamine) effects
vasoconstriction by causing the release of norepinephrine at postganglionic
nerve endings. Several mental disorders and health conditions are explained as
due to either an excess or deficiency of monoamines. There are many natural
tryptamines in both animal and plant as well as synthetics modified by chemical
constituents and substituted at appropriate positions in the motif. Common
tryptamine class compounds include;
- Bufotenine
(CAS #: 487-93-4): (5-Hydroxy-N,N-dimethyltryptamine, pressor agent,
epinephrine-like.
- DMT (CAS #:
61-50-7): N,N-Dimethyltryptamine, a psychedelic and
hallucinogenic.
- Melatonin
(CAS #: 73-31-4, 8041-44-9): N-Acetyl-5-methoxytryptamine, biological clock
hormone.
- Psilocin:
4-Hydroxy-N,N-dimethyltryptamine.
- Psilocybin
(CAS #: 520-52-5): 4-Phosphoryloxy-N,N-dimethyltryptamine, a
hallucinogenic.
- Serotonin
(CAS #: 50-67-9): 5-Hydroxytryptamine, a vasoconstrictor.
- Sumatriptan(
CAS #: 103628-46-2) 4-Hethylaminosulfonyl-N,N-dimethyltryptamine, selective
serotonin antagonist used in the treatment of migraine headache.
