How many chiral centres in ibuprofen
Web1 Hardikar Hospital, Pune 411005. PMID: 19552094 Abstract A chiral centre is noted in majority of the NSAIDs. For NSAIDs the enantiomer with S configuration almost exclusively possesses the ability to inhibit prostaglandin activity. R-enantiomers of NSAIDs have poor COX inhibitory activity. WebRacemic mixture. In chemistry, a racemic mixture, or racemate ( / reɪˈsiːmeɪt, rə -, ˈræsɪmeɪt / ), [1] is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates.
