WebDiastereomeric drugs (multiple chiral centers) A large number of drugs have multiple chiral centers. The total number of isomers possible is 2(n) where n is the number of chiral centers present in the molecule. In the example below (Figure 8), each isomer has one enantiomer where the stereochemistry at both chiral centers are inverted.

[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. WebAs an example, thalidomide (56) is a chiral drug, once used to relieve morning sickness, and ... simply life menu
