Interrogating contrastive learning embeddings for structure-based virtual screening: a case study on DrugCLIP
This paper systematically evaluates DrugCLIP's contrastive learning embeddings for structure-based virtual screening, revealing that while its pocket embeddings offer fast and robust structural similarity search and its ligand embeddings capture pocket-aware chemical patterns with strong generalization to unseen targets, performance is significantly limited by conformational variations and inaccuracies in predicted protein pockets.
