Summarizing activity and selectivity in one picture

Summarizing activity and selectivity in one picture was presented by Dr Mark Mackey, Cresset at the Cresset European User Group Meeting 2015.


3D-QSAR based on molecular interaction potentials can provide a wealth of information about the exact molecular characteristics required for activity. However, current techniques have a number of issues such as alignment noise, sampling errors and descriptor choice which can make it difficult to reliably produce effective models. We have presented in the past techniques for solving the sampling problem and shown that using accurate electrostatics combined with simple shape descriptors often gives meaningful models. However, there are still times when it is not possible to obtain a statistically valid linear regression model.

One useful qualitative data analysis method that is being increasingly used is activity cliffs analysis. In this technique, pairs of compounds are located that are similar (in some sense),

Web clip: Simple pictorial summaries of SAR with Activity Atlas Models

Forge, Cresset’s computational workbench for ligand-based design, uses ligand alignment to decipher complex SAR in shape and electrostatic space. As well as simple visual inspection Forge is able to use:

  • 3D-field-QSAR: To build a linear model for activity
  • Activity Miner: Find and analyze individual activity cliffs
  • Activity Atlas: Build a global view of activity cliffs, explored regions of SAR, and summarize activity space using shape and electrostatics.

This web clip gives an introduction to Activity Atlas Models in Forge.

If you have any questions about this functionality please contact us.
