LIGAND exists to make the molecular reality of medicine visible — a structural reference for pharmacologists, and an open door for anyone who's ever wondered what's actually in the pill they're taking.
199 real compounds, rendered live from PubChem and RCSB PDB — not illustrations.
Every compound is color-coded by class — teal for small molecules, violet for biologics — and its real molecular structure animates into focus the moment you look at it. Try it below.
Nothing here is illustrated or approximated. Every structure, mechanism, and fact traces back to one of these public databases — click through and see it yourself.
3D conformers, molecular formulas, and identifiers for every small molecule
Real crystal and cryo-EM structures for biologics and complex small molecules
FDA-approved labeling — mechanism of action, indications, dosing
Target protein identities, sequences, and function
