BioPharmics Surflex Platform 5.197

The Surflex Platform consists of the five modules described below. The Surflex Manual contains details of all computational procedures and options within each command-line module. We support Linux (most common variants), Windows, and MacOS. All of the modules are multi-core capable, and very substantial speed-ups are observed with modern multi-core laptops, workstations, and HPC clusters.

Tools Module
Fast and Accurate Small Molecule Processing

The Tools module addresses the most common aspects of small-molecule preparation
2D to 3D conversion (from SMILES or SDF)
Chirality detection and enumeration
Protonation
Conformer generation

Features and benefits
Template-free and non-stochastic
Relies on MMFF94sf forcefield for structure derivation
Fast and accurate on typical drug-like ligands, with better coverage of diverse conformations
Fastest and most accurate method for macrocyclic ligands
Capable of incorporating NMR restraints, which is particularly useful for large peptidic macrocycles

Similarity Module
State-of-the-Art 3D Molecular Similarity

The Similarity module implements ligand similarity operations using the eSim method
Virtual screening
Pose prediction
Multiple ligand alignment
The core eSim methodology is also integrated into the Docking and QuanSA modules.

Features and benefits
Virtual screening enrichment is both practically and statistically significantly better than alternative methods
Virtual screening speeds of over 20 million compounds per day on a single computing core
Databases of billions of molecules can be screened in hours using cloud-based computing resources
Pose prediction accuracy is substantially better than alternative approaches

Docking and xGen Modules
Top-Tier Solution for Virtual Screening and pose Prediction + Real-Space X-ray Density Modeling of Ligands

The Docking module addresses all aspects of ensemble docking
Large-scale PDB retrieval and processing
Surface-based binding site alignment using the PSIM method
Fully automatic pocket variant selection to cover the relevant protein conformational variation
Virtual screening
Pose prediction
