A medicinal chemist modifies a drug molecule to increase its binding affinity for a specific receptor while decreasing its affinity for other related receptors. This process is known as:

NSAIDs like ibuprofen work by inhibiting COX enzymes. This classifies them as:

In enzyme kinetics, the concentration of a drug required to inhibit an enzyme's activity by 50% is represented by which value?

A drug undergoes a metabolic reaction where a methyl group is transferred to it. This reaction is categorized as:
