Compound Selection
Problem: Prioritizing a Lead Series
In pre-clinical drug development, a series of compounds is developed through lead
optimization. Once a lead series has been established, one compound must be selected
for first-in-human trials. Making this decision requires a wide range of information.
Even though targeted toxicity data may exist, there is no information on the overall
level of biochemical perturbation. Being able to see how a drug impacts the global
biochemical profile can help prioritize leads.
Solution: Survey the Biochemical Landscape
Metabolon's comprehensive
biochemical profiling service
surveys the biochemical landscape. This global perspective provides insight into
the relative effects of a series of drugs on the animal model. This insight can
also lead to a better understanding of both the target and off-target effects.
Case Study: Protease Inhibitors
Objective
Examine a series of protease inhibitors to show the relative amount of biochemical
perturbation.
Method
- HepG2 and adipocytes in cell culture (10% FCS) were treated with five protease
inhibitors and a control.
- Metabolomic analysis was performed on each group.
Results
The figure below shows the global metabolomic profile (as Z-plots) for each compound
and the control. Each dot represents a different biochemical and the deviation from
the central tendency shows the extent of biochemical perturbation. The green shaded
boxes of each panel highlight the biochemicals with significant fold changes. These
changes were mapped to physiological differences seen in animal models. In this
case, compound 1 was the most desirable since it showed the fewest metabolic changes.
