We developed a machine learning approach using random forest (RF) to improve virtual screening. This method efficiently identifies potential drug inhibitors, reducing experimental testing for drug discovery.

Area of Science:

  • Computational chemistry
  • Cheminformatics
  • Machine learning in drug discovery

Background:

  • Virtual high-throughput screening (HTS) is crucial for identifying drug candidates.
  • Flexible docking methods predict molecular interactions but can be computationally intensive.
  • Experimental validation of HTS results requires significant resources.

Purpose of the Study:

  • To apply the random forest (RF) supervised machine learning algorithm to flexible docking results.
  • To reduce the number of compounds needing experimental testing in drug discovery.
  • To extend the predictive power of docking studies to entire chemical libraries.

Main Methods:

  • Utilized the random forest (RF) machine learning algorithm.
  • Applied RF to flexible docking data from five virtual HTS studies.

  • Tested the approach on compounds from the MDL drug data report (MDDR).

    • Main Results:

    • Achieved over 90% recall for five diverse protein targets, with some reaching 100% performance.
    • Identified 60% of active compounds by docking only 10% of screened ligands for most targets.
    • Demonstrated high accuracy in predicting biological activity of small molecule inhibitors.

    Conclusions:

    • The RF machine learning method combined with flexible docking is an effective strategy for virtual HTS.
    • This in silico approach rapidly scans large databases to predict inhibitor activity.
    • Offers an efficient alternative to more computationally demanding virtual screening methods.
