GalaxySagittarius

GalaxySagittarius predicts protein targets for druglike compounds by integrating structure- and similarity-based approaches to identify potential protein–ligand interactions.

Key Features:

• Hybrid Approach: Combines ligand similarity-based screening with receptor structure-based docking to identify candidate protein targets.
• Efficient Screening: Performs a preliminary screening using structural similarity and known interactions to narrow candidate proteins and reduce downstream docking calculations.
• Molecular Docking: Conducts protein–ligand docking on selected candidates to predict binding modes and relative affinities.
• Comprehensive Database Enrichment: Predicts binding ligands and sites to enrich the database with novel protein targets and interaction annotations.

Scientific Applications:

• Drug discovery: Facilitates identification of novel protein targets for druglike compounds to support lead identification and target hypothesis generation.
• Drug repurposing: Enables discovery of alternative targets for existing compounds to support repurposing and exploration of new therapeutic uses.

Methodology:

An initial structure- and similarity-based screening is followed by molecular docking on a curated subset of proteins.
