Computational Drug Discovery

Rank ten thousand molecules. Synthesize ten.

DrugSynq simulates protein-ligand binding at atomic resolution — scoring candidates by predicted binding affinity and ADMET risk before your chemists touch a flask.

The Problem

The synthesis bottleneck isn't chemistry. It's prioritization.

Most discovery teams synthesize the top 50–100 molecules from a virtual screen — and 90% of them fail for reasons a physics-based simulation would have flagged. DrugSynq narrows that list before the first reaction.

The Platform

Three simulation layers, one ranked list.

Binding Affinity Ranking

Free-energy perturbation (FEP) calculations rank candidates by predicted ΔG binding, not just docking score. Physics-grounded prioritization for the full lead series.

ADMET Risk Scoring

12 ADMET properties per candidate — permeability, metabolic stability, hERG liability, aqueous solubility — scored and ranked alongside binding affinity.

Molecule Prioritization

Multi-parameter optimization surface combining affinity, ADMET, and synthetic accessibility into one ranked synthesis queue ready for the bench.

The Science

Physics-based, not just pattern-matched.

DrugSynq uses alchemical free energy methods grounded in statistical mechanics — not just ML regression on existing activity data. That means better extrapolation into novel chemical space.

Our FEP calculations use the OPLS4 force field with enhanced sampling techniques, achieving r² = 0.82 correlation against experimental IC50 measurements in retrospective validation across diverse target classes.

Validation

Benchmark performance on retrospective datasets.

We validate against publicly available crystal structure sets and published activity series to demonstrate predictive accuracy before you run your own campaign.

Retrospective benchmarks across diverse target classes show r² = 0.82 Pearson correlation between predicted and experimental ΔG values, with median absolute error of 0.78 kcal/mol.

From the Field

What computational chemists say.

"DrugSynq cut our lead optimization synthesis cycle from 14 compounds per round to 6. The ADMET ranking alone removes the obvious failures before they hit the bench."

Dr. Priya Ramachandran
Principal Computational Chemist, San Diego biotech

"We were spending two weeks running our own FEP calculations per series. Now we upload the library on Monday and have the ranked list by Wednesday. That time goes back into chemistry."
