(S,S)-(+)-Ethambutol is powerful and selective antitubercular drug.It is a typical example of an old drug that was introduced for clinical use in its unichiral form. . Ethambutol contains two constitutionally symmetrical chiral centers in its structure and exists in three stereoisomeric forms, the enantiomeric pair (+)-(S,S)- and (−)-(R,R)-ethambutol, along with the achiral stereoisomer called m
Glyceraldehyde has one chiral center and therefore exists as two different enantiomers with opposite optical rotation: In the D/L nomenclature, either D from Latin Dexter meaning "right", or L from Latin Laevo meaning "left" In the R/S nomenclature, either R from Latin Rectus meaning "right", or S from Latin Sinister meaning "left"
The ideal kinetic resolution is that in which only one enantiomer reacts, i.e. k R >>k S. The selectivity (s) of a kinetic resolution is related to the rate constants of the reaction of the R and S enantiomers, k R and k S respectively, by s=k R /k S, for k R >k S. This selectivity can also be referred to as the relative rates of reaction.
The (R)-enantiomer has the desired sedative effect while the (S)-enantiomer harbors embryo-toxic and teratogenic effects. Attempting to extract solely R -thalidomide does not remove the risk of birth defects, as it was demonstrated that the "safe" R -thalidomide undergoes an in vivo chiral inversion to the "teratogenic" S -thalidomide.
