Ligand-based Drug Design

Ligand-based drug design (LBDD) refers to drug discovery efforts in the absence of any target structure and in the presence of chemical structures known to modulate the target. Ligand-based drug discovery starts with a single compound or a group of compounds known to be effective against a target, and based on knowledge of the structure-activity relationship (SAR), improves potency and other important properties by designing appropriate analogs. Design can be done by the Topliss method or a simple analog design based on structural similarities or properties. CD ComputaBio now offers professional ligand-based drug design service to meet your research needs.

Our Services

In the absence of reliable protein structural information, CD ComputaBio is able to apply a range of ligand-based drug design tools to advance the drug discovery process at various stages:

  • We can use scaffold hopping and fragment replacement tools, which have proven to be a very effective strategy for generating new IP and ideas for backup series, or replacing structural elements associated with metabolic instability or unwanted properties.
  • We use several pharmacophore techniques and alignment methods based on ligand shape and electrostatic similarity, which can be used to compare different series of compounds and their structure-activity relationship (SAR) data, or for virtual screening to rapidly identify new potential active compound.
  • Ligand-based Drug Design2

  • Local QSAR models (2D and 3D), matched molecular pair analysis, and machine learning using project data can all be used to predict the potency of new compounds against targets of interest and ADMET properties. These can be used together to create multi-objective optimization protocols.
