Question 3

Many drugs exist as enantiomers, and often only one enantiomer is pharmacologically active or has a more favorable therapeutic profile. What is the main reason for this difference in biological activity between enantiomers?

Accepted Answer

B. Differential interaction with chiral biological targets (receptors, enzymes). — Enantiomers, being chiral molecules, can interact differently with chiral biological targets such as receptors, enzymes, and ion channels. This differential interaction at the molecular level leads to variations in their pharmacological activity, potency, metabolism, and sometimes toxicity. While enantiomers have identical physical properties in an achiral environment (like melting points or water solubility), their biological effects diverge due to the chiral environment of the body.

Answer

A. Differences in melting points and boiling points.

Answer

C. Variations in their solubility in water.

Answer

D. Their ability to rotate plane-polarized light in opposite directions.
