Chirality of thalidomide
Did you know?
WebThalidomide is a drug that presents two enantiomers with markedly different pharmacological and toxicological activities. It is sadly famous due to its teratogenic effects mostly caused by the preferential docking of the … 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.
WebOct 22, 2024 · In 1961, thalidomide was first introduced as an over-the-counter cure for morning sickness. Pregnant women across the country began to take the drug, which worked well, but shortly after, babies began to be born with severe birth defects. WebOptical Isomerism In Thalidomide.

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.
