CPP Research & Data Styles

in vivo CPP Research

“Treating the bed to cure the patient”

Field Tests

Same as in vivo, but with less control!

“Extra” dataDegradation and movement in the

environment are major issues

Data Issues

Biological variability(Highly) Multivariate dataEC50 results are uncommonHistorical data is valuable

Successful Applications of Data Visualization

Sourcing: Preformatted data sets for sample acquisition analysis

Hit Followup: R-group visualization and analysis

Lead Optimization: Color-coded reports for rapid, high-dimensional comparisons

Browsing Acquisition Analysis Data

Challenge: Characterize and evaluate offerings from compound brokers and collaborators

Solution: External system to characterize offerings and build tables for browsing in Spotfire

Minimal interface...

User selection from existing “evaluation tables”

Spotfire for browsing

Parallel Synthesis Hit Followup

Visualization and analysis of combinatorial library

Row and Column layout useful, but not chemically relevant!

Merging synthetic schemes combined with biology

Hansch-style characterization often helpful for identifying trends and features

Fragment properties and whole molecule data can provide insights

NR1

R2

R1 == methyl, ethyl, propyl, etc

R2 == -F, -Cl, -Br, -I

Plate layout vs. Fragment Data

Lead Optimization

Numerous test and characterization values for each compound

Future Challenges

Better data extraction/formatting techniques

Expanding data warehouse to include non-traditional data sources

Computer screen real estate!
