BBB-Nuke: 1 Billion Compound Blood-Brain Barrier Permeability Screen
Overview
1.02 billion small molecules screened for blood-brain barrier (BBB) permeability using the BBB-Nuke pipeline (v0.12.0).
Screening Pipeline
Each compound was scored through:
- Standardization - SMILES canonicalization via RDKit
- Physicochemical properties - MW, LogP, TPSA, HBD, HBA, Fsp3, heavy atom count
- pKa prediction - Representative pKa via MolGpKa (batched GCN inference)
- CNS-MPO scoring - Multi-parameter optimization (6 properties)
- Efflux transporter prediction - 8 efflux proteins (S1 fingerprint RF classifiers)
- Classifier + heuristic - Final P_BBB probability score (5-fold CV AUROC 0.933)
