Which method uses a target-based assay and robotic automation to test thousands of compounds in a few days?

• A. Combinatorial Chemistry
• B. Structure-Based Drug Design
• C. Analogues of natural ligands
• D. High-Throughput Screening

Answer: (D)

High-Throughput Screening is all about rapidly testing large numbers of compounds against a defined biological target using automated, robotic-assisted workflows. The target-based assay means each well measures how a compound affects the target—whether it inhibits or activates the target’s activity—so you can quickly identify potential hits. Robotic liquid handling, microplate readers, and data-automation allow thousands to millions of compounds to be evaluated in parallel in just a few days. This speed is the hallmark of HTS and what enables efficient early-stage hit discovery. Combinatorial chemistry focuses on generating very large libraries of compounds through parallel synthesis, which is about making diverse molecules efficiently, not necessarily evaluating them in a high-throughput biological screen. Structure-based drug design uses knowledge of the target’s 3D structure to design or optimize molecules, often through computational methods, rather than large-scale empirical screening. Analogues of natural ligands involve modifying known natural ligands to explore activity, not performing automated, large-scale target screening.
