Which percentage of hits are of synthetic origin?

Which percentage of hits are of synthetic origin?

• A. 12%
• B. 6%
• C. 25%
• D. 50%

Answer: (D)

In hit discovery, hits come from both natural product libraries and synthetic compound libraries. Synthetic libraries are designed to be extremely large and diverse, allowing rapid generation and testing of many distinct chemotypes. Natural products, while biologically rich, are limited by availability and complexity. Because of these library dynamics, roughly half of hits tend to originate from synthetic sources. That’s why the percentage of hits of synthetic origin is about 50%. The smaller percentages would imply a much smaller contribution from synthetic compounds, which isn’t typical given how screening campaigns are built.
