This study found that random compound selection methods are effective for high throughput screening. Utilizing BCUT descriptors improved analysis compared to principal components, confirming model-based compound selection enhances screening success.

Area of Science:

  • Medicinal Chemistry
  • Computational Chemistry
  • Drug Discovery

Background:

  • Designing effective screening sets for high throughput screening (HTS) is crucial for drug discovery.
  • Statistical strategies and chemical descriptors significantly impact the efficiency of compound selection.

Purpose of the Study:

  • To evaluate and compare different statistical strategies for compound selection in HTS.
  • To assess the utility of various chemical descriptors for analyzing screening sets.
  • To determine the impact of compound selection methods on screening hit rates.

Main Methods:

  • Examined three compound selection strategies: random, clustering, and space-filling designs.
  • Utilized two types of chemical descriptors: BCUTs and principal components of Dragon Constitutional descriptors.
