Molecular Dynamics (MD)

LigandScout XT seamlessly integrated Molecular Dynamics (MD) simulations takes structural biology and molecular design to the next dimension, by breaking down the barriers of setting up complex computational physics and furthermore integrating analysis tools geared for molecular design and virtual screening.

No Technical Barriers - Intuitive and Easy MD Set-up

Powered by the industry-leading, GPU-accelerated OpenMM engine, LigandScout XT transforms what is typically a daunting, command-line-heavy process into a highly intuitive, visual workflow.

With just a few straightforward clicks, users can seamlessly prepare protein-ligand complexes, automatically assign robust force-field parameters, define custom solvation boxes, and deploy high-performance OpenMM simulations without ever writing a single line of code.

Traditionally, setting up rigorous MD simulations required navigating convoluted command-line interfaces, piecing together intricate parameter scripts, and manually defining complex system topologies — a daunting bottleneck that often slowed down rapid drug discovery efforts.

LigandScout XT completely removes this technical barrier by offering an incredibly intuitive, fully GUI-driven experience that democratizes dynamic simulations for medicinal chemists and computational scientists alike.

Integrated Tools and Ultra Fast Simulations

This deeply integrated, user-friendly workflow means that evaluating the temporal stability of a target compound, uncovering cryptic sub-pockets, or observing the dynamic evolution of critical pharmacophore interactions over time is no longer an arduous technical chore and it is ultra fast.

Dynamic Pharmacophores

Beyond simply generating simulations, LigandScout XT revolutionizes how you interpret complex MD trajectory data through its innovative dynamic pharmacophore tools. Analyzing the massive amounts of data generated during an MD run can be overwhelming, but our software streamlines this by automatically extracting and tracking key 3D-pharmacophore interaction features across the entire simulation enabling visualization of buried information such as

  • the stability of critical ligand-receptor interactions
  • transient but crucial binding events that static crystal structures might miss, and intuitively frequency of interaction patterns.

By bridging the gap between rigorous MD and intuitive advance dynamic pharmacophores LigandScout XT provides actionable, deep-level insights into target flexibility and compound efficacy.

By effortlessly transforming static structural snapshots into fluid, time-resolved dynamic models directly from the interface, LigandScout XT empowers discovery teams to rapidly validate binding modes, refine their in silico SAR, and rigorously de-risk lead candidates prior to synthesis.
