Outline

  • Many Key Properties Can be Estimated Individually in silico
  • Acid/base dissociation constants (pKa ’s) & ionization
  • Solubility and tendency to supersaturate
  • Lipophilicity
  • Intestinal permeability
    • quantitative: passive permeability & local models
    • qualitative: susceptibility to active uptake or efflux on transporters
  • Metabolism
    • quantitative: cytochrome P450 (CYP) clearance & local models
    • qualitative: glucuronidation & glutathione conjugation
  • Binding to plasma proteins, to red blood cells & within tissues
