Area of Science:

  • Computational chemistry
  • Drug discovery
  • Medicinal chemistry

Background:

  • IC50 determination is vital for drug development but experimentally challenging.
  • Existing quantitative structure-activity relationship (QSAR) methods for IC50 prediction require extensive datasets.
  • There is a significant need for advanced computational tools for in silico drug design.

Purpose of the Study:

  • To enhance a quantum computation-based IC50 prediction method.
  • To minimize the amount of known data required for accurate IC50 prediction.
  • To develop a more accessible computational approach for drug efficacy assessment.

Main Methods:

  • A relative IC50 computation approach was employed.
  • The method requires only the IC50 of a similar reference compound.
  • Dipole moments of unknown and reference compounds are utilized.

Main Results:

  • The refined method was validated using organic and organometallic compounds.
  • Tested applications include HIV-1 capsid A inhibitors and anticancer drugs.
  • Computed IC50 values demonstrated strong agreement with experimental data.

Conclusions:

  • The developed method is broadly applicable to organic and organometallic compounds with high accuracy.
  • The approach simplifies IC50-based drug discovery by requiring only dipole moments.
  • An algorithm for IC50-driven drug searching has been proposed.
