Metabolite Identification
Common NamePhenylpropiolic acid
DescriptionPhenylpropiolic acid is an acetylenic compound that is propynoic acid in which the acetylenic hydrogen is replaced by a phenyl group. It is an alpha,beta-unsaturated monocarboxylic acid, an acetylenic compound and a member of benzenes. It derives from a propynoic acid. Phenylpropiolic acid is one of a number of phenylpropanoid, natural products occurring in plants pathways involved in plant resistance providing building units of physical barriers against pathogen invasion, synthesizing an array of antibiotic compounds, and producing signals implicated in the mounting of plant resistance. (PMID 15199968 ). Phenylpropiolic acid is a cis-pyrrolidinone that has been tested as an inhibitors of type II 17beta-hydroxysteroid dehydrogenase for the treatment of osteoporosis. (PMID 16806919 ). Phenylpropiolic acid (C6H5CCCO2H) is formed by the action of alcoholic potash on cinnamic acid dibromide (C6H5CHBrCHBrCO2H), crystallizes in long needles or prisms which melt at 136–137 °C. When heated with water to 120 °C, it yields phenylacetylene (C6H5CCH). Chromic acid oxidizes it to benzoic acid; zinc and acetic acid reduce it to cinnamic acid, C6H5CH=CHCO2H, whilst sodium amalgam reduces it to hydrocinnamic acid, C6H5CH2CH2CO2H. Ortho-nitrophenylpropiolic acid, NO2C6H4CCCO2H, prepared by the action of alcoholic potash on ortho-nitrocinnamic acid dibromide, crystallizes in needles which decompose when heated to 155–156 °C. It is readily converted into indigo.
