Discngine Chemistry Collection
The Discngine Chemistry Component Collection is an extension to the standard Chemistry package for Pipeline Pilot. Generate and visualize scaffold networks, perform exhaustive molecular fragmentation or use Pharmacophore Graph to design powerful Matched Molecular Pairs analysis & lead hopping applications.
Fuzzy MMP Analysis using Pharmacophore Graphs to enable MMPA for smaller datasets and improved statistical significance
Highly customisable reduced graph representation to perform lead hopping
3D Pharmacophore Graph components allowing matching & filtering
Out-of-the-box scaffold networks and recursive molecular fragmentation
Scientifically validated Fuzzy Pharmacophore Triplet Fingerprints
Try it yourself!
This application demonstrates the use of Discngine Pharmacophore Graph for lead hopping. The goal of the strategy is to identify compounds structurally different from the reference (query) compounds yet displaying similar biological activity.
The graph matching score as well as the Accelrys Pipeline Pilot ECFP_4 fingerprint based similarity measure is shown, the higher the graph matching score, the better. Similarly, the lower the fingerprint based similarity, the more structurally different the compounds are.
The dataset is composed of active compounds extracted from PubChem as well as 76 marketed drugs that were selected as reference (query) compounds to screen the pubchem data subset against.
