Impact of collaborative pKa modelling

Authors: Reutlinger M
Software: ADMET Predictor®

pKa has many impacts in drug discovery, such as:

  • Affects absorption, distribution, metabolism and excretion
  • Safety profile (off-targets liabilities, e.g. hERG inhibition)
  • Binding with membranes, membrane analogs and proteins.
  • Can affect drug-receptor binding (salt-bridge formation, desolvation)
  • Useful in formulation, manufacturing and process control pKa is the key parameter for other physchem properties, such as
  • Lipophilicity
  • Solubility
  • Permeability
  • Dissolution
