Reason: strain 42.5 kcal/mol
strain ΔE 42.5 kcal/mol 3 protein-contact clashes 3 intramolecular clashes 74% of hydrophobic surface is solvent-exposed (17/23 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 1 HBA 5 HY 2 PI 1 CLASH 3

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.
