WebThe enantiomers of thalidomide were determined by direct resolution on a tribenzoyl cellulose column. Mean rate constants of chiral inversion of (+)-(R)-thalidomide and (-)-(S)-thalidomide in blood at 37 degrees C were 0.30 and 0.31 h-1, respectively. Rate constants of degradation were 0.17 and 0.18 h-1. WebThalidomide (1957-1961) Morning sickness treatment Cause congenital abnormalities ... W. A.

WebChirality and drug toxicity. Thalidomide carries one stereogenic center at the C-3 of the 2,6-piperidine-2,6-dione ring and hence the molecule exists as an enantiomeric pair. The (R)-enantiomer has the desired sedative effect while the (S)-enantiomer harbors embryo-toxic and teratogenic effect.
