WebSep 11, 2024 · The drug thalidomide is an interesting - but tragic - case study in the importance of stereochemistry in drug design. First manufactured by a German drug … WebTwenty years after the thalidomide disaster in the late 1950s, Blaschke et al. reported this only the (S)-enantiomer of thalidomide is teratogenic. However, other work can shown that the enantiomers of thalidomide interconvert in vivo, which begged an question: why is teratogen activity not observes in animal experiments that use (R)-thalidomide provided … WebBackground: Thalidomide has a chiral centre, and the racemate of (R)- and (S)-thalidomide was introduced as a sedative drug in the late 1950s. In 1961, it was withdrawn due to teratogenicity and neuropathy. There is now a growing clinical interest in thalidomide due to its unique anti-inflammatory and immunomodulatory effects. how did call the midwife end
