Thalidomide and chirality

Web22 Jan 2024 · Thalidomide is the small synthetic compound α-phthalimido-glutarimide (IUPAC systematic name, 3-(RS)-2-(2,6-dioxo-3-piperidyl)isoindole-1,3-dione), which possesses one chiral centre (the C3-carbon atom of the glutarimide ring), and comprises a racemic mixture of two optical isomers, (R)- (also (+)-) and (S)- (also (−)-) enantiomers, … 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 …

WebThalidomide is racemic; while S-thalidomide is the bioactive form of the molecule, the individual enantiomers can racemize to each other due to the acidic hydrogen at the chiral centre, which is the carbon of the glutarimide ring bonded to the phthalimide substituent. The racemization process can occur in vivo.

Something is considered to be chiral if it cannot be superimposed on its own mirror image – in other words, if it is asymmetric (lacking in symmetry). The term ‘chiral’ is derived from the Greek word for ‘handedness’ – ie. right-handedness or left-handedness. Your hands are chiral: your right hand ... boys of the old brigade chords
