WebCircular dichroism spectroscopy used for the stereochemical characterization of the hydroxylated metabolites formed during the in vitro biotransformation of (R)- and (S)-thalidomide indicated that the chiral center of thalidomide is unaffected by the stereoselective biotransformation process (Meyring et al., 2002). WebChemical compounds that come as mirror-image pairs are referred to by chemists as chiral or handed molecules. Each twin is called an enantiomer.Drugs that exhibit handedness are referred to as chiral drugs.Chiral drugs that are equimolar (1:1) mixture of enantiomers are called racemic drugs and these are obviously devoid of optical rotation. The most …

Herein, we show that replacement of the exchangeable hydrogen at the chiral center with deuterium allows the stabilization and testing of individual enantiomers for two thalidomide analogs, including CC-122, a compound currently in human clinical trials for hemato-logical cancers and solid tumors. WebAug 12, 2024 · Thalidomide contains a chiral center, and thus exists in two enantiomeric forms. It was marketed as a racemic mixture: in other words, a 50:50 mixture of both …
WebMar 9, 2015 · The chiral center of these thalidomide analogs is chemically unstable, resulting in interconversion of the enantiomers both in vitro and in vivo. Through … 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 molar ratio of enantiomers and is referred to as a racemic mixture (i.e. contain equal amount of (+) and (−) forms).
