Bioinformatics
Machine learning in drug discovery

Background:

High-throughput screening (HTS) data in PubChem offers valuable insights into small molecule activities.
Analyzing HTS data is challenging due to large volumes and imbalanced active/inactive compound ratios.
Luciferase-based HTS assays are common, necessitating methods to identify interfering compounds.

Purpose of the Study:

To develop a robust computational model for analyzing imbalanced HTS assay data.
To identify and filter potential interference compounds in luciferase-based HTS experiments.
To create an efficient virtual screening tool for HTS data analysis.

Main Methods:

Utilized the granular support vector machines (SVMs) repetitive under sampling (GSVM-RU) method.
Constructed a support vector machine (SVM) model using imbalanced luciferase inhibition bioassay data (1/377 active/inactive ratio).
Validated the model using cross-validation and blind tests.

Main Results:

The GSVM-RU model achieved high accuracy in recognizing active (86.60%) and inactive (88.89%) compounds, with an overall accuracy of 87.74%.
Demonstrated robustness in handling imbalanced HTS data, proving effective as a virtual screening tool.
Showcased computational efficiency, reducing costs and facilitating adoption for other biological systems.

Conclusions:

The developed GSVM-RU model is effective for analyzing imbalanced HTS data and identifying interference compounds.
The model serves as a valuable virtual screening tool for luciferase-based HTS experiments.
The computational efficiency and adaptability of the method make it suitable for broader HTS data analysis.
