Building a Quantitative Structure-Property Relationship (QSPR) Model.

Methods in molecular biology (Clifton, N.J.)·2019

Area of Science:

  • Computational chemistry
  • Drug discovery
  • Pharmacokinetics

Background:

  • Predicting drug pharmacokinetic properties (ADME/toxicology) is crucial for successful drug development.
  • Traditional QSAR methods often fall short in capturing the complexity of pharmacokinetic behavior.
  • Accurate prediction requires integrating molecular properties with biological factors like solubility and membrane penetration.

Purpose of the Study:

  • To develop a robust QSPR strategy for predicting pharmacokinetic drug properties.
  • To create a method applicable to structurally diverse datasets, maximizing detailed structural information.
  • To enable early identification of drug leads with potential pharmacokinetic liabilities.

Main Methods:

  • Combined molecular interaction fields with Soft Independent Modeling of Class Analogy (SIMCA).

  • Utilized Idiotropic Field Orientation (IFO) for molecular alignment of diverse compound sets.
  • Developed a variation of IFO incorporating electrostatics into molecular alignment.

    • Main Results:

    • IFO successfully oriented diverse molecular structures for field analysis.
    • SIMCA models were developed for human intestinal absorption, blood-brain barrier penetration, and bioavailability.
    • The method demonstrated utility in identifying compounds with poor pharmacokinetic profiles early in development.

    Conclusions:

    • The developed method effectively predicts key pharmacokinetic properties using molecular fields and SIMCA.
    • IFO provides a robust approach for aligning structurally diverse molecules.
    • This tool aids in the early screening of drug candidates, reducing pre-clinical attrition.
