Are you struggling with SAR tables? Finding it hard to keep all the SAR in your mind? With Activity Atlas, a new component in Forge, you can easily summarize complex SAR as a 3D visualization. Activity Atlas enables you to:
- understand complex selectivity data at a glance
- condense a large table of SAR data into a single picture
- analyze the SAR of your data series from different viewpoints.
“Activity Atlas 3D visualizations (Figure 1) tell you what active molecules have in common, which regions you have explored, and help you pinpoint critical regions of SAR,” explains Dr Giovanna Tedesco, Forge Product Manager. “This information is very valuable for new molecule design and we believe it will particularly benefit project teams where there is not enough SAR for a traditional 3D-QSAR approach.”

Figure 1: Activity Atlas visualization of the critical SAR regions for three receptors: Adenosine A1, Adenosine A2a and Adenosine A3. [Published activity data taken from J. Bajorath, J. Chem. Inf. Model. 51, 258-266, 2011] This information could direct the next molecule design iteration towards (for example) maintaining potency at the A1 receptors while building in selectivity towards A2 and A3. Color coding: Red: more positive increases activity; Blue: more negative increases activity; Green: steric bulk in this position is favorable; Magenta: steric bulk in this position is detrimental.
