• This technology has the potential to accelerate the drug development process and improve treatment outcomes.

Summary
Turkish scientists have made a significant breakthrough in drug development by creating a computational model that can accelerate the process of designing and testing therapies. This new technology, developed by associate professor Özge Kürkçüoğlu and her student Merve Yüce at Istanbul Technical University, targets the "control rooms" of viruses and disease-causing proteins, offering a data-driven pathway to streamline drug development.

The research focuses on the "second secret of life," also known as allostery, which explains how proteins change shape to regulate biological processes. The team's "Residue Interaction Network" (RIN) model maps out hidden switches in proteins, allowing for the design of highly selective drugs with fewer side effects.

Key insights include:
• The model can predict structural changes in proteins after a drug binds.
• It successfully identified known drug-binding sites with 89.2% accuracy.
• The model's specificity was measured at 89.7%, with a sensitivity of 80.0%.

The study demonstrates the potential for computational models to dramatically shorten the early stages of drug design. This technology could prove especially valuable in global health emergencies, such as the COVID-19 pandemic, where accelerating drug discovery timelines is crucial.

The research has been published in the journal Proteins and offers a cost-effective solution for identifying allosteric regions, eliminating the need for expensive and labor-intensive laboratory experiments. The team's work has reached a critical stage for the pharmaceutical sector, providing a road map for next-generation therapeutics.

The model's ability to interpret "allosteric communication signals" could play a critical role in designing highly selective drugs with fewer side effects. The multiscale coarse-grained anisotropic network model (mcgANM) used in the study can predict structural changes in proteins that will occur after a drug binds.

The development of this digital 'scalpel' has the potential to revolutionize the field of drug development, enabling targeted and efficient treatment of diseases. As we move forward, it will be exciting to see how this technology is applied and the impact it has on human health.
