Question 4

The drug thalidomide is known for its tragic history due to severe teratogenic effects. Chemically, thalidomide exists as a racemic mixture of two enantiomers. Which statement best explains the pharmacological significance of these enantiomers?

Accepted Answer

C. The enantiomers readily interconvert in vivo, making their separation for clinical use impractical. — While one enantiomer (R-thalidomide) was initially thought to be responsible for the sedative effect and the other (S-thalidomide) for teratogenicity, it's crucial that these enantiomers rapidly interconvert in vivo under physiological conditions. This interconversion means that even if a single enantiomer were administered, both forms would be present in the body, making it impossible to avoid the teratogenic effects by administering only one isomer.

Answer

A. Both enantiomers are equally potent and have similar therapeutic and toxic effects.

Answer

B. One enantiomer is therapeutically active, while the other is responsible for the teratogenic effects.

Answer

D. The therapeutic effect is solely due to the R-enantiomer, and the S-enantiomer is inactive.
