Integrated Platform
The five modules of the BioPharmics Surflex Platform (Tools, Similarity, Docking, xGen, and Affinity) are fully integrated. The full software bundle provides a comprehensive predictive modeling workflow:
- 2D to 3D molecular conversion, with accurate chirality interpretation and enumeration facilities
- Conformer elaboration including complex macrocycles, also supporting the use of NMR restraints
- Protein structure preparation and alignment
- Docking for pose prediction or virtual screening
- Real-space modeling of ligands as conformational ensembles within X-ray density maps
Software is available for Windows, Linux, and Mac platforms, with easy deployment across on-premises workstations and laptops as well as cloud-based computing resources.

JCAMD: Macrocycle Optimization
February 26, 2024
We have published a study, with our colleagues from Corteva, demonstrating active-learning with QuanSA for lead-optimization of a macrocyclic natural product. This is in addition to our recent comprehensive study of complex macrocycle optimization through careful application of NMR restraints combined with molecular docking, molecular similarity, and estimation of bound ligand strain with colleagues from BMS.
JMC: Strain/xGen Papers
January 27, 2023
We have published a comprehensive study of bound ligand strain with colleagues from Merck and BMS. This adds to a paper looking at peptide macrocycle strain energetics in the context of real-space refined ligand conformational ensembles. Both studies build on the xGen methodology where we showed that conformational ensembles, without atom-specific B-factors, are better models for ligands in terms of both fit to X-ray density and strain energy.
JCIM: QuanSA and FEP+
December 10, 2021
A focused machine-learning approach to inducing binding site models with QuanSA is shown to be complementary and synergistic with predictions from FEP+ across 17 targets. The paper reports significant reductions in prediction errors and consistent improvements in compound rank-ordering by combining the results of QuanSA and FEP+.
