Density Functional Theory-Based Studies Predict Carbon Nanotubes as Effective Mycolactone Inhibitors

Area of Science:

• Computational Chemistry
• Materials Science
• Biomedical Engineering

Background:

• Fullerenes, boron nitride nanotubes (BNNTs), and carbon nanotubes (CNTs) are widely studied for biomedical applications.
• Mycolactone is a toxin associated with certain diseases, and its inhibition is of significant interest.
• Understanding the interaction of nanomaterials with toxins is crucial for developing novel therapeutic strategies.

Purpose of the Study:

• To investigate the potential of BNNTs and CNTs as inhibitors of mycolactone.
• To explore the chemical properties and interaction mechanisms between mycolactone and armchair BNNTs (5,5) and CNTs (5,5) using computational methods.

Main Methods:

• Density Functional Theory (DFT) calculations were employed to study the adsorption and interaction energies.
• Analysis of optimized structures and intermolecular interactions between mycolactone and the nanotubes.
• Investigation of electronic properties using Density of States (DOS) plots and HOMO-LUMO orbital studies.

Main Results:

• Mycolactone can be stably adsorbed onto armchair CNTs through physical adsorption.
• Adsorption of mycolactone on CNTs does not significantly alter the electronic properties of the nanotubes.
• Interaction energies suggest that CNTs are more favorable for mycolactone adsorption than BNNTs due to strong π-π interactions.

Conclusions:

• Armchair CNTs demonstrate potential as effective inhibitors of mycolactone.
• The findings support the exploration of CNTs as promising agents for mitigating mycolactone toxicity in biological systems.
• Further research into CNT-based mycolactone inhibition strategies is warranted.
