3d-qsar

3d-qsar constructs three-dimensional quantitative structure–activity relationship (QSAR) models using Py-CoMFA, a Python implementation of Comparative Molecular Field Analysis (CoMFA), to correlate molecular interaction fields with biological activity.

Key Features:

• Py-CoMFA Implementation: Implements Comparative Molecular Field Analysis (CoMFA) in Python to generate three-dimensional QSAR models.
• Molecular Interaction Field Analysis: Calculates molecular interaction fields (MIFs) to correlate spatial chemical properties of compounds with biological activity.
• Pre-Aligned Dataset Modeling: Supports construction of QSAR models from pre-aligned molecular datasets.
• Molecular Alignment Tools: Provides computational functions for generating molecular alignments required for CoMFA-based modeling.
• Benchmark Validation: Demonstrates model performance consistent with original CoMFA implementations based on evaluation across 30 publicly available datasets.

Scientific Applications:

• Drug Discovery: Supports identification of structural determinants influencing biological activity of chemical compounds.
• Structure–Activity Relationship Analysis: Enables investigation of relationships between three-dimensional molecular structures and pharmacological activity.
• Chemoinformatics Research: Facilitates computational modeling and analysis of molecular interaction fields in medicinal chemistry studies.

Methodology:

The method applies Py-CoMFA to compute molecular interaction fields for aligned molecular datasets and uses Comparative Molecular Field Analysis to correlate spatial interaction fields with biological activity in three-dimensional QSAR models.
