Scientific capability / Ensemble Reaction-Barrier Ranking

Would a different protein conformation change the chemistry ranking?

A reaction barrier at one geometry can hide the conformational dependence of a proposed warhead. BioTwin’s ranking methods compare matched chemistry across modeled conformers before choosing what to synthesize.

Compare the series under the same assumptions

Single-geometry calculations offer a useful reference. The ensemble approach asks whether the relative rates change across conformers and how weighting those conformers affects the ranking. Consistent methods and convergence checks matter as much as the apparent difference between candidates.

A relative ranking with a defined scope

The toolkit contains barrier and rate-calibration methods for computational investigation. Constrained energy scans need further checks before they can be interpreted as verified transition states. A stable ranking does not by itself establish absolute reaction rates.

Connect accessibility to reactivity carefully

Ensemble ligandability can identify conformations worth examining; reaction calculations can ask what chemistry they support. That connection requires compatible structures and weights. It should be tested as a composition rather than assumed from the two methods’ availability.

Choose the experiment that calibrates the ranking

Use a defined chemical series with measured reaction rates. Check whether the ranking survives plausible sampling and method changes before making it the basis for a larger synthesis campaign.

Choose a series that can test the ranking.

A defined reaction, related candidates and relevant conformers provide a starting point for a bounded computational comparison.
