Reason: 8 internal clashes, strain 51.4 kcal/mol
strain ΔE 51.4 kcal/mol
8 protein-contact clashes
8 intramolecular clashes
68% of hydrophobic surface is solvent-exposed (13/19 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

HBD/HBA · H-bonds (geometric)
HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: strict. Residues: 6.
PI · π–π interactions
Native π–π recall is disabled because no explicit native π–π reference was stored.

Native ligand reference
★ reference
Interaction fingerprint calculated directly from the uploaded native ligand without docking. Current H-bond mode: strict.
