Web9 Mar 2015 · Unfortunately, the development of some chirally pure drug molecules is hampered by rapid in vivo racemization. The class of compounds known as immunomodulatory drugs derived from thalidomide is developed and sold as racemates because of racemization at the chiral center of the 3-aminoglutarimide moiety. WebThalidomide as the ( R) enantiomer is effective against morning sickness, while the ( S) enantiomer is teratogenic, causing birth defects when taken in the first trimester of pregnancy. If only one enantiomer is administered to a human subject, both forms may be found later in the blood serum. [7] http://www.k-faktor.com/thalidomide/racemization.htm sycho sid bret hart

WebRacemization. In chemistry, racemization is a conversion, by heat or by chemical reaction, of an optically active compound into a racemic (optically inactive) form. This creates a 1:1 … WebThalidomide ( 1) possesses an asymmetric carbon, and the drug has been used as a racemic mixture. A widely prevailing hypothesis is that only the S -isoform of thalidomide is teratogenic, and therefore, if R -thalidomide had been used, the thalidomide disaster could have been avoided.
