IChem

IChem generates precise molecular topology descriptions to support structure-based ligand design and protein–ligand interaction analysis.

Key Features:

• Molecular topology description: Produces precise descriptions of molecular topology for three-dimensional (3D) structures.
• Ligand and cofactor atom typing: Performs detailed atom typing for ligands and cofactors.
• Water molecule identification: Identifies critical water molecules involved in molecular interactions.
• Protein–ligand interaction analysis: Detects, analyzes, and compares protein–ligand interactions.
• Representation conversion: Converts 3D molecular structures into simplified representations such as fingerprints or graphs.
• Automation for throughput: Automates tasks to support high-throughput analysis and reduce subjective variability in modeling.

Scientific Applications:

• Structure-based ligand design: Provide topology and interaction data to inform structure-based ligand design computations.
• Protein–ligand detection and comparison: Enable detection, analysis, and comparison of protein–ligand interactions in structural datasets.
• Knowledge extraction and screening: Facilitate rapid knowledge acquisition and high-throughput analysis via fingerprints or graphs.
• Drug discovery and development: Support drug discovery and development projects that require precise modeling of molecular interactions.

Methodology:

Performs ligand and cofactor atom typing, identifies critical water molecules, converts three-dimensional (3D) structures into fingerprints or graphs, and automates detection, analysis, and comparison of protein–ligand interactions.
