Predicting drug properties from structure is reliable. Structural similarity to known drugs accurately forecasts their classification, medical effects, and targets, aiding new drug discovery.

Area of Science:

  • Computational chemistry
  • Drug discovery
  • Bioinformatics

Background:

  • The World Health Organization's Anatomical Therapeutic Chemical (ATC) classification links drug structure to therapeutic use.
  • The hypothesis that similar physicochemical properties correlate with similar biological activity is widely accepted.
  • Predicting drug properties based on structural similarity is a key area in pharmaceutical research.

Purpose of the Study:

  • To validate the reliability of predicting drug class, medical indication, and molecular targets based on structural similarity.
  • To assess the correlation between physicochemical property similarity and the accuracy of predicted medical effects.
  • To develop a web-server for predicting drug properties of novel compounds.

Main Methods:

  • Utilized the Anatomical Therapeutic Chemical (ATC) classification system for drug categorization.
  • Developed a web-server that translates user-defined molecules into structural fingerprints.
  • Compared structural fingerprints against a database of ~6300 drugs with ~7300 curated links to molecular targets.
  • Employed the Tanimoto coefficient to quantify structural similarity between compounds.

    • Main Results:

    • Validated the reliable prediction of drug class for WHO-classified drugs.
    • Demonstrated that the accuracy of predicted medical effects increases with higher physicochemical similarity to known drugs.
    • Achieved 81% correct ATC prediction for similarity scores above 0.85.
    • Established that biological effects are predictable given sufficient structural similarity.

    Conclusions:

    • Structural similarity is a reliable predictor of drug classification and therapeutic effects.
    • The developed web-server enables accurate prognoses for novel compounds' medical indications.
    • The tool facilitates the identification of new drug leads for known molecular targets.
