  • Drug discovery

Background:

  • Chemical structure privacy is crucial for the pharmaceutical industry.
  • Sharing physico-chemical and biological data can enhance molecular understanding and drug development.
  • Current methods risk disclosing proprietary molecular information.

Purpose of the Study:

  • To determine theoretical limits of information required for reverse engineering molecules from descriptors.
  • To propose a novel strategy for sharing chemical data securely.
  • To validate the effectiveness of surrogate data for predictive modeling.

Main Methods:

  • Analysis of information content of molecular descriptors.
  • Development and application of surrogate data sharing strategy.

  • Prediction of lipophilicity using both original and surrogate data.

    • Main Results:

    • Molecular information content can be as low as less than one bit per atom.
    • A single descriptor can theoretically reveal a complete molecular structure.
    • Surrogate data provides similar predictive ability to original data for lipophilicity.
    • The proposed strategy allows sharing of predicted molecules without compromising structural privacy.

    Conclusions:

    • Sharing surrogate data is a viable method to share chemical information securely.
    • This approach protects proprietary molecular structures while enabling data analysis.
    • The strategy can accelerate drug discovery by facilitating data sharing.
