Docking Rush — Quick Guide

Your Mission Manipulate the investigational drug molecule in 3D to fit inside the active site cavity. Satisfy critical Hydrogen Bonds, bury hydrophobic anchors, and avoid Steric Overlaps to lower the predicted binding free energy (ΔG) below the threshold for clinical lead progression!

3D Biophysical Visual Cues

Cyan Beams

Active Hydrogen Bonds (≤3.2 Å). Awards -1.6 kcal/mol per bond.

Red Halos

Severe Steric Clashes (<1.75 Å). Incurs +3.2 kcal/mol penalty and blocks assay approval.

Amber Highlights

Hydrophobic packing into non-polar subpockets (e.g. Met165, Val523, Ile50).

Rotamer Conformations

Cycle rotatable bonds to find induced-fit shapes without steric clashes.
