Polymerizable Matrix Metalloproteinases' Inhibitors with Potential Application for Dental Restorations.

Area of Science:

• Biomaterials Science
• Dental Materials
• Polymer Chemistry

Background:

• Matrix metalloproteinases (MMPs) degrade collagen, a primary cause of dental resin restoration failure.
• Existing MMP inhibitors often exhibit toxicity, limiting their use in dental applications.
• Developing safe and effective inhibitors is crucial for improving the longevity of dental restorations.

Purpose of the Study:

• To synthesize and evaluate a novel class of MMP inhibitors designed for dental resin applications.
• To assess the co-polymerizability and safety profile of these inhibitors within dental resin formulations.
• To investigate the potential of these inhibitors to enhance the long-term stability of dental restorations.

Main Methods:

• Computational docking was used to predict the affinity of synthesized compounds to MMP active sites (MMP-1, -2, -8, -9, -13).
• Selected compounds were synthesized and their cytotoxicity was evaluated using two distinct cell types.
• Co-polymerization potential with commercial dental resin components was assessed to evaluate in-situ safety.

Main Results:

• Computational analysis identified promising MMP inhibitory properties for several synthesized compounds.
• The synthesized compounds demonstrated low toxicity to tested cell lines, even at high concentrations.
• Co-polymerization with dental resins further improved compound safety by limiting their release.

Conclusions:

• A new class of co-polymerizable MMP inhibitors has been developed for dental applications.
• These inhibitors show potential for reducing dental resin degradation caused by MMPs.
• Co-polymerization offers a promising strategy to enhance the safety and efficacy of MMP inhibitors in dental materials.
