Natural Product Identification
Common Name11beta-Hydroxyandrost-4-ene-3,17-dione
DescriptionPhenmetrazine, also known as oxazimedrine or preludin, belongs to the class of organic compounds known as phenylmorpholines. These are aromatic compounds containing a morpholine ring and a benzene ring linked to each other through a CC or a CN bond. Phenmetrazine also acts as a monoamine oxidase inhibitor. Phenmetrazine is a drug which is used as an anorectic in the treatment of obesity. Phenmetrazine is a very strong basic compound (based on its pKa). Its actions and mechanisms are similar to dextroamphetamine. Phenmetrazine is a potentially toxic compound. It is this latter effect on the tubero-infundibular systm that seems to lead to reduced food intake. 11beta-Hydroxyandrost-4-ene-3,17-dione was first documented in 1964 (PMID: 14196928). Metabolism involves deamination to para-hydroxyamphetamine and phenylacetone; this latter compound is subsequently oxidize to benzoic acid and excreted as glucuronide or glycine (hippuric acid) conjugate (PMID: 23211394) (PMID: 4125018) (PMID: 5356063).
