WebJun 11, 2024 · There are mainly two kinds of chiral inversions in the drugs which includes unidirectional and bidirectional inversions. The most common example of unidirectional inversion is of NSAIDs including ketoprofen, ibuprofen and fenprofen etc. For this group only S-enantiomer is active and shows anti-inflammatory and analgesic properties. WebA chiral switch is a chiral drug that has already approved as racemate but has been re-developed as a single enantiomer. [1] [2] The term chiral switching was introduced by Agranat and Caner in 1999 [3] to describe the development of single enantiomers from racemate drugs. For example, levofloxacin is a chiral switch of racemic ofloxacin.
