Why selected: Genetically and chemically validated antiparasitic target with multiple ligandable pockets beyond the canonical cofactor site.

Scaffold cluster scatter

Butina clustering (Morgan radius 2, threshold=0.4). Each point is one pose, coloured by scaffold cluster. X = docking score, Y = inter norm.

Cluster summary

Score vs. physicochemical properties

Docking score on Y-axis; physicochemical descriptor on X-axis. Colour = H-bond count.

Interaction fingerprint heatmap

Binary contact matrix: rows = compounds (sorted by score), columns = binding-site residues (sorted by contact frequency). Dark cell = contact present.

Enrichment curves

X = fraction of database screened, Y = fraction of native residue contacts recovered. Steeper = better early enrichment.

Enrichment factors

Pose RMSD diversity

For each compound with ≥ 2 stored poses: max pairwise RMSD vs. best docking score. High RMSD = docking samples multiple binding modes.

Top diverse compounds

Ligand efficiency landscape

LE = −score / HAC  |  LLE = −score − LogP  |  LLEAT penalises large compounds. Colour = H-bond count.

Top compounds by LE

Binding-site interaction frequency

Stacked bar: blue = H-bond frequency, orange = hydrophobic contact frequency. Percentage of top-100 poses making each contact.

Consensus pharmacophore (≥50% poses)

Inter norm vs. intra norm

X = intermolecular score (more negative = better). Y = intramolecular strain. Red points have intra > 40 % of |inter| — likely strained artefacts.

Most strained poses

Filter distribution

Ro3 (fragment-like), Lead-like, Ro5 pass/violations, PAINS.

Score by filter category

Box plot of docking score distribution per drug-likeness class.

Score distribution per scaffold (violin)

Top 15 scaffolds by compound count. Wide violin = large score range within the scaffold class.

Top ΔScore pairs (same scaffold)

Sorted by |ΔScore|. Compounds A and B share a Murcko scaffold.

Scaffold summary

Similarity vs. ΔScore

Each point = a compound pair. Red = activity cliff (Tanimoto ≥0.8, |ΔScore| ≥1.0). High-similarity pairs with large score differences indicate sensitive SAR regions.

Top cliff pairs

Mean score per substituent

R-group decomposition against the most common Murcko scaffold. Bars show mean docking score per substituent; more negative = better.

Substituent table

Chemical space PCA

PCA of 7 physicochemical descriptors (MW, LogP, TPSA, HBA, HBD, RotBonds, Rings). Colour = docking score. Hover for compound details.

H-bond partner frequency

How often each binding-site residue forms an H-bond across all poses.

Score vs. H-bond count

H-bond count distribution

Top H-bond partners

Residue contact breakdown

Stacked bar: total contacts (grey) split into H-bond (blue) and hydrophobic (orange) components. Top 40 residues by total contact frequency.

Pareto front: score vs. ligand efficiency

Gold stars = Pareto-optimal compounds — no other compound has both a better score AND a better LE. These are the best multi-objective candidates.

Pareto-optimal compounds

Synthetic accessibility vs. docking score

X = SA score (1 = easy to synthesise, 10 = very hard) or Fsp3 if SA scorer unavailable. Y = docking score. Colour = QED drug-likeness. Bottom-left = best hits.

3D pose overlay

Top-12 poses by rank score overlaid in the binding pocket. Requires 3Dmol.js (loaded via CDN).

Overlay error: 'DockingPose' object has no attribute 'mol_block'

Burial score vs. docking score

Burial = contact count / heavy-atom count. Higher burial = ligand more deeply buried in pocket. Colour = H-bond count.

Burial score distribution

Top buried compounds

Cross-experiment score comparison

Bar chart comparing best docking score per compound across all experiments in the database. Only compounds present in ≥2 experiments are shown.

Selectivity table

ΔScore = max − min across experiments. Higher = more experiment-selective.

Torsion angle distribution

Rose/polar histogram of rotatable bond dihedral angles across all poses. Gauche (50–130°), anti (<30° or >150°).

Gauche / Anti summary

Per-compound torsion spread

IFP binding-mode clusters

Butina clustering on binary residue-contact fingerprints (threshold=0.4). Each point = one pose, coloured by cluster.
