ADME in Discovery and Development (1)
• Discovery:– Objective: Fail hits early
– Samples: Dry and DMSO-dissolved
– Throughput: Up to 200 samples/day (typically)
– Accuracy: (Supposedly) not high – rank order is sometime sufficient
• Development:– Objective: Optimize lead (better ADME parameters),
salt & excipient selection, QSAR, etc.
– Samples: Dry
– Throughput: Typically up to 100/day, but increasing
– Accuracy: High, must use gold-standard validated assays

ADME in Discovery and Development (2)
• State-of-the-art today:– Discrete instruments, each performing a single assay– Data consistency between different assays non-existent– Significant interaction required from trained personnel– No process engineering methodologies:
• When assay is not required, the system is idle• When a system is down, there is no replacement• To double the capacity, each system must be duplicated
• Automated Discovery Workstation:
The modern approach to the entire lab

Automated Discovery Workstation - ADW
• Not an instrument: It is an integrated solution (lab-on-a-bench)
• Machine work – people think
• Turnkey, automated, multi-assay workstation
• Performs (presently) discovery/development assays:– True LogD/LogP vs. pH
– True aqueous solubility vs. pH
– Identity and purity of compound
– Compound concentration w/o standard
• Scalable, Flexible, Extendable technology
• Standardized, validated data

Two Key ADME Assays2. Solubility
• Solubility is the concentration of the compound in solution in equilibrium with its solid
• Important for bioavailability and other ADME processes
• Very sensitive to measurement methodology
• Current profiling solubility indicators are frequently different from the true values
• Direct solubility assay (shake flask = gold standard)
• Unique features:– No sample weighting
– No assay calibration required to calculate solubility as mass/volume

Solubility
• Solubility is the concentration of the compound in solution in equilibrium with its solid
• Solubility takes several forms and is a function of multiple parameters (crystalline form, temperature, pH, co-solvent, etc.)
• Important for bioavailability• Very sensitive to measurement methodology• Current profiling solubility indicators in early discovery are
frequently different from the true values obtained during development
• A direct solubility assay is defined by the shake flask method and is recognized as the gold standard

• Discovery:– Obtain a measure of solubility of relevance to HTS and
early ADMET• Can we determine if the compound will crash out of solution?
– Obtain ADMET information of relevance for selecting amongst hits
• Development:– Early lead characterization

Basic Issue:What is the Effect of DMSO?
Typically:• DMSO is a fact of life during screening• DMSO solubility is > or >> than true solubility• But just because we relaxed one experimental
parameter does not mean that we can dispense with everything else
• Make sure you know what you are using the data for – especially in lead promotion decisions
