Ligand based drug design
Ligand based approach is one of the fastest and widely used methods to identify and optimize new hits.
- Chemical space visualization, clusterization based on scaffolds and similarity metrics
- Predictive QSAR models
- Pharmocophore models, 3D alignment
- Conformational analysis
- Combinatorial chemistry and in silico generation of new structures
- Scaffold hopping and fragment replacement
- Synthesability assessment of generated structures

Structure based drug design
If reliable structural information about target and/or mode of ligand binding is available, structure based methods could accompany ligand based approaches to help in design and optimization of novel compounds.
- Protein structure refinement, loop modeling
- Binding site identification
- Homology modeling
- Flexible docking – induced fit, etc.
- Docking based QSAR models (Docking to Protein Pocket Classification/Regression (dpc) models as implemented in Molsoft package)
- Molecular dynamics studies for additional analysis of binding mode

Hit2lead optimization
Hit to lead optimization extensively uses both structure-based and ligand-based methods.
We provide:
- Rapid analysis of hits obtained by high throughput screening (HTS)
- Chemical space visualization of obtained hits
- In silico profiling:
○ ADMET optimization
○ Scaffold hopping
