Dual-LAO for calculating fast and robust relative binding free energies of simple and complex transformations
Communications Chemistry, Published online: 08 May 2026; doi:10.1038/s42004-026-02022-6Relative Binding Free Energy (RBFE) calculations are essential for drug discovery but are often hindered by high computational costs and limited reliability for complex transformations. Here, the authors introduce the Dual-LAO framework integrating Lambda-ABF-OPES, dual topology, and dual-DBC restraints, that accelerates RBFE calculations by 15 to 30 times, maintains high accuracy and tackles previously prohibitive molecular changes.
