Pharmacophore
Pharmacophore — The ensemble of steric and electronic features required for optimal interaction between a peptide and its target receptor.
What Is a Pharmacophore?
A pharmacophore is the minimal set of structural features (specific atoms, functional groups, and their spatial arrangement) required for a peptide to bind its target and produce a biological effect. Pharmacophore identification enables design of smaller, more drug-like peptidomimetics that retain the essential binding interactions.
Determination
- Ala scan: Identifies critical side chains contributing to activity
- SAR: Systematic substitution maps the pharmacophore elements
- Computational: Overlay active analogs to identify common 3D pharmacophore features
- Co-crystal: X-ray structure of peptide-receptor complex reveals contact residues directly
