Physicochemical profiling

The structural and physicochemical characteristics of drug candidates underpin:

  • how they interact with biological systems, including absorption across biological membranes
  • how they are metabolised by the liver and other organs
  • how they are distributed throughout the body
  • how they interact with their intended biological target—as well as 'off-target' interactions, which often lead to unwanted effects or toxicity

Through analysis of structural and molecular properties related to a compound's physicochemical characteristics, it is possible to gain qualitative insight into many of these interactions, and to use this information to design molecules with favourable characteristics for a specific disease area.

CDCO's systems and methods have been adapted to handle small-scale quantities of material, assessing their physicochemical, biopharmaceutical, solid-state and stability characteristics.

Research platforms include:

  • in silico predictions of physiochemical properties
  • kinetic solubility and solubility in simulated biological fluids
  • chromatographic and shake-flask Log D
  • chromatographic protein-binding
  • pKa determination
  • short-term solution stability
  • solid-state characterisation
  • salt-form screening
  • impurity profiling
