One model scores peptide PK and toxicity from SMILES or sequence
- Accepts either SMILES or amino acid sequences, so natural, modified, cyclic and peptide-like inputs are covered; predicts permeability (Caco-2, PAMPA), half-life, clearance, distribution volume, neurotoxicity and hemolysis.
- Trained on data compiled from public databases and literature; several encodings and model families, from classical ML to transformers and language models, were compared.
- Adds a function-aware score judging suitability given a peptide's intended activity. Reported good accuracy and interpretability on independent test sets (retrospective, no experimental validation described in the abstract).
Peptide ADME data is small, noisy and scattered across assay protocols, so a single model spanning Caco-2, PAMPA, half-life and clearance deserves a hard look at split design: random splits on near-identical sequences inflate scores. Ask whether the test sets were clustered by sequence or scaffold, and whether it beats a simple baseline on your own cyclic or modified series before trusting any number.
