What is an advantage of target-centered drug design?

• A. Assays are always straightforward regardless of target.
• B. If the hit interacts with the target, then it has a relatively high likelihood of useful pharmacologic activity.
• C. The approach cannot be used if the target is known.
• D. It does not facilitate design of targeted assays.

Answer: (B)

Target-centered drug design focuses on crafting molecules that specifically engage a defined biological target. The main advantage is that when a hit actually interacts with that target, it has a higher chance of showing useful pharmacologic activity because the observed effect is directly tied to modulating that particular target. This targeted approach lets you optimize for potency and selectivity around the binding site and tailor properties that support engagement in the body, reducing the risk of activity that doesn’t translate to the intended mechanism. It also guides the development of assays that measure direct target engagement or functional modulation, making it easier to distinguish true, mechanism-based effects from off-target noise.
