Determination of proton affinities and pKa values of small organic molecules​

Background

This study uses DFT calculations to predict proton affinities and pKa values for small organic and drug-like molecules, aiming to design organic super-acids that enhance drug-target interactions and efficacy. The approach allows precise tuning of pKa values to improve drug properties and selectivity.​

Question of Interest

Can we use silico method to proton affinities and pKa values accurately for organic molecules/drug-like molecules ​

Methods

Computational methods​ of quantum chemical calculations (DFT) to examine the proton affinities (pKa).​

Results

Rational Design of Organic cyclopentadiene​ based super-acids and their proton affinities​  

Impact

  • We design small drug-like molecules with optimized proton affinities (pKa), ensuring enhanced drug-target interactions and efficacy.​
  • Quantum chemical calculations enable precise tuning of pKa values, offering a novel approach to improving drug properties and selectivity.​
