Phenylpropanolamine (PPA), sold under many brand names, is a sympathomimetic agent used as a decongestant and appetite suppressant. [ 9 ] [ 1 ] [ 10 ] [ 11 ] It was once common in prescription and over-the-counter cough and cold preparations .
Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis. From 4-coumaroyl-CoA emanates the biosynthesis of myriad natural products including lignols (precursors to lignin and lignocellulose ), flavonoids , isoflavonoids ...
1-Amino-2-propanol Betaxolol Metoprolol Nadolol Pindolol Propranolol Timolol. Propanolamines are a class of chemical compounds, many of which are pharmaceutical drugs. They are amino alcohols that are derivatives of 1-amino-2-propanol.
Some β-hydroxyamphetamines have had their side chain extended and cyclized.Examples include certain substituted phenylmorpholines like phenmetrazine and phendimetrazine and their analogues; substituted phenylmorpholines related to bupropion like radafaxine (cyclized (2S,3S)-hydroxybupropion) and manifaxine; certain substituted aminorexes like 4-methylaminorex and 4,4'-dimethylaminorex; and ...
Interactions between chemical compounds also is a frequent area of taxonomy, as are the major organic chemistry categories (protein, carbohydrate, lipid, etc.) that are relevant to the field. In the field of aroma and flavor alone, Flament gives a list of 300 contributing chemicals in green beans, and over 850 after roasting.
pentobarbital – humane euthanasia of animals not to be used for food; pentoxyfylline – xanthine derivative used in as an antiinflammatory drug and in the prevention of endotoxemia; pergolide – dopamine receptor agonist used for the treatment of pituitary pars intermedia dysfunction in horses; phenobarbital – anti-convulsant used for ...
The original packaging used the phrase "Ayds Reducing Plan vitamin and mineral Candy"; a later version used the phrase "appetite suppressant candy". The active ingredient was originally benzocaine, [1] presumably to reduce the sense of taste to reduce eating, later changed in the candy (as reported by The New York Times) to phenylpropanolamine. [2]
In organic chemistry, propanolamine can describe any of the following parent compounds: [1]. 2-Amino-1-propanol, the hydrogenated derivative of alanine.; 3-Amino-1-propanol, straight-chain and not widely used.
