Description

Molecular modelling has become an indispensable tool in pharmaceutical and biomedical research, driving advancements in drug discovery, protein engineering, and disease modelling. Recent innovations have significantly enhanced the precision and efficiency of these computational techniques. The integration of Artificial Intelligence (AI), such as machine learning-driven protein structure prediction tools like AlphaFold, has revolutionized structural biology. Quantum mechanics/molecular mechanics (QM/MM) hybrid models now enable detailed insights into enzymatic reactions and complex biological processes, while enhanced Molecular Dynamics (MD) simulations allow researchers to explore molecular conformations with unprecedented accuracy [5].

Applications of molecular modelling include identifying potential drug candidates through docking studies, understanding protein-ligand interactions, and uncovering biomarkers for early disease diagnosis. These tools are also instrumental in designing biologics, such as CRISPR systems and monoclonal antibodies.

Discussion

Recent advancements in molecular modelling have significantly influenced pharmaceutical and biomedical research, offering enhanced tools for drug discovery, protein engineering, and disease modelling. While the integration of AI and QM/MM models has improved the accuracy of molecular simulations, challenges such as computational costs and scalability persist. High-fidelity simulations for large bimolecular systems demand substantial resources, limiting their accessibility for smaller research institutions. Accuracy remains another limitation, as experimental validation is often required to complement computational predictions. Despite advancements in algorithms, achieving consistent precision in modelling rare conformational states and multi-protein interactions remains difficult. Furthermore, integrating molecular modelling data with experimental workflows requires better standardization and efficient data-sharing frameworks. However, the potential for future developments is immense. Cloud-based platforms and open-source tools are making molecular modelling more accessible, while ongoing improvements in AI and machine learning promise greater predictive power. Personalized simulations tailored to individual patients could redefine precision medicine, enabling customized therapeutic strategies [9,10].

Molecular modelling has significantly transformed pharmaceutical and biomedical research, providing insights that drive breakthroughs in drug discovery, biomarker identification, and disease modelling. By simulating molecular interactions and predicting biological responses, it has become indispensable for understanding complex biological systems. Recent innovations, such as the integration of Artificial Intelligence (AI) and hybrid quantum mechanics/molecular mechanics (QM/MM) models, have substantially enhanced the precision and applicability of molecular modelling. AI accelerates data analysis and predictions, while QM/MM approaches improve the accuracy of simulations at the atomic level. Together, they enable the exploration of novel therapeutic targets, optimizing drug development pipelines and minimizing failure rates. Despite its remarkable progress, challenges such as computational cost, scalability, and accuracy in complex systems remain. Addressing these limitations will not only enhance the utility of molecular modelling but also cement its role as a cornerstone in advancing therapeutic innovations, personalized medicine, and the future of healthcare.
