2 protein-contact clashes
90% of hydrophobic surface is solvent-exposed (18/20 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: permissive. Residues: 1.
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: permissive.
