Phenylethyl is a structural skeleton found in sympathomimetic amines that
have important physiological functions within the body as neurotransmitters in
the central nervous system and hormones in the blood circulation. Phenyl ketone
structure is found in keto alkaloids such as cathinone, a contributor of
stimulant effect. Phenyl ketone is a fuel in the brain.
Propiophenone (Phenyl ethyl ketone) is
a useful intermediate to prepare nervous system drugs (anxiolytic and hypnotic drugs).
Bupropion
is an example which has propiophenone moiety. Bupropion is an aminoketone class
antidepressant.
Propiophenone is used in the synthesis of ketoamphetamines
such as cathinone and methcathinone. Propiophenone can also be converted
to synthetic aryl alkenes such as cinnamic acids.
some propiophenone derivatives such as paroxypropione (4-hydroxypropiophenone)
is a drug called adrenergic beta-antagonist which
bind to but do not activate beta-adrenergic receptors thereby
blocking the actions of beta-adrenergic agonists. Adrenergic beta-antagonists
are used for treatment of hypertension, cardiac arrhythmias, angina pectoris,
glaucoma, migraine headaches, and anxiety. Propiophenone is a constituent of synthetic perfumes, flavouring agents, and of
paints to stabilize other
ingredients. Ketones can be made by the oxidation of secondary alcohols and the destructive
distillation of certain salts of organic acids. In addition to as polar
solvents, ketones are important intermediates in the syntheses of organic
compounds such as alkoxides, hydroxyalkynes, imines, alcohols (primary,
secondary as well as tertiary), acetals, thioacetals, phosphine oxides, geminal
diols, hydrazones, organic sulfite and cyanohydrins. Propiophenone is a clear liquid that is insoluble in water, but miscible with methanol, ethanol, diethyl ether, benzene and toluene.
Butyrophenone
is the basic structure of antipsychotic drugs such as
CNAntipsychotic agents control agitated psychotic behavior, alleviate acute
psychotic states, reduce psychotic symptoms, and exert a quieting effect. They
are used in schizophrenia, senile dementia, transient psychosis following
surgery or myocardial infarction, etc. These drugs are often referred to as
neuroleptics alluding to the tendency to produce neurological side effects, but
not all antipsychotics are likely to produce such effects. Many of these drugs
may also be effective against nausea, emesis, and pruritus. ydroxy
or methoxy butyrophenone (Desaspidin).
