Anthranilate derivatives as TACE inhibitors: docking based CoMFA and CoMSIA analyses

Area of Science:

• Medicinal Chemistry
• Computational Chemistry
• Pharmacology

Background:

• Anthranilic acid derivatives (ANTs) represent a novel class of compounds.
• Tumor necrosis factor-α converting enzyme (TACE) is a validated drug target.
• Understanding TACE inhibition mechanisms is crucial for drug development.

Purpose of the Study:

• To investigate the molecular interactions between ANTs and TACE.
• To identify structural features responsible for TACE inhibitory activity.
• To develop predictive models for designing novel TACE inhibitors.

Main Methods:

• Molecular docking simulations to predict binding modes.
• Comparative Molecular Field Analysis (CoMFA) and Comparative Molecular Similarity Indices Analysis (CoMSIA) for 3D-QSAR.
• Validation of QSAR models using test sets.

Main Results:

• CoMSIA model demonstrated high predictive power (r²(test) = 0.871).
• Detailed insights into the atomic interactions within the TACE binding site were obtained.
• A strong correlation was observed between 3D-QSAR descriptors and TACE binding site features.

Conclusions:

• Computational approaches effectively elucidate TACE/ANT interactions.
• The developed QSAR models can guide the rational design of potent ANTs.
• This study provides a foundation for developing improved TACE inhibitors for therapeutic applications.
