State is read from the file, not from its title. A structure titled “apo” is often ligand-free and G-protein-coupled, which is the active state.

A control has been verified experimentally, by structure or by assay, so its prediction can be checked; an experimental compound is under investigation, with nothing to check against. Experimental compounds are ringed in red in the charts.
2 named pocket(s) (41Y, V6G) plus an unconstrained baseline; contacts are enforced within 4 A.

Ligand pose vs experiment
6 target(s) compared against experimental structures in reference/. Atoms are paired by molecular graph, so the symmetry of the ligand is respected rather than being resolved by whichever atom happened to be nearest. Not compared: 7E14 is not a structure of GIPR; 7RBT is not a structure of GLP1R.

Chemistry notes
LSN1
ionizable group(s) present (primary/secondary amine, phenol) -- verify the SMILES reflects your intended protonation state

Scaffolds: Bemis-Murcko, exact match first, then Tanimoto-clustered (Morgan r=2, 2048-bit, threshold 0.60) whole-group MCS as a verified fallback. Minimum highlighted substructure size: 8 heavy atoms. Stereocentre/ionizable-group highlighting from this campaign's own ligand-preparation check (see above).
