strain ΔE 51.7 kcal/mol 5 protein-contact clashes 5 intramolecular clashes 70% of hydrophobic surface is solvent-exposed (14/20 atoms). Large non-polar area without protein contacts incurs a desolvation penalty and will reduce binding affinity. Consider truncating or replacing the exposed fragment.

Interaction summary

HBD 2 HBA 5 HY 2 PI 1 CLASH 5

HBD/HBA · H-bonds (geometric)

HBD = ligand donates H · HBA = ligand accepts H · ~ = weak (≥110°). Mode: permissive. Residues: 5.

PI · π–π interactions

Native π–π recall is disabled because no explicit native π–π reference was stored.

HY · Hydrophobic contacts

CLASH · Clashes

Native ligand reference

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