Ligand preparation

2 of 2 ligand(s) flagged for chemistry review -- these are advisory, not errors; verify the input SMILES reflects what you intended before trusting the results below.

Ligand Chemistry notes
ISO1 undefined stereocentre(s) at atom index 5; ionizable group(s) present (primary/secondary amine, phenol) -- verify the SMILES reflects your intended protonation state
PRO1 undefined stereocentre(s) at atom index 5; ionizable group(s) present (primary/secondary amine) -- verify the SMILES reflects your intended protonation state

Ligand structures

No shared scaffold or substructure detected across the set -- ligands are structurally distinct.

Landlord narration

2 of 2 target summaries written on-device by the Apple Neural Engine; 0 rendered from the template. Every number here is checked against the figures the analysis computed; a summary stating one it was not given was replaced by the template.

The adrb2_gs campaign predicted structures for two ADRB2 targets, ISO1 and PRO1. One of the two targets was marked caution and the other proceed. The campaign was not successful because one of the two targets carried at least one flag.

Key findings

Highest predicted potency

Caveats

Overall confidence is below the well-determined threshold, so the structure should be treated with caution.

Per target

TargetVerdictSummaryCaveatWritten by
ADRB2_ISO1cautionThe structure is moderately determined, so it's not very reliable for making decisions. ISO1 is an agonist that binds to the receptor but has a high uncertainty about its potencyOverall confidence is below the well-determined threshold, so the structure should be treated with caution.model
AR2NG_PRO1proceedWell determined, meaning that the predicted structure is likely to be correct. PRO1 is an unspecified ligand with a binder probability of 0.997 and predicted potency of 12.41, with no interaction analysis run.The predicted structure is not supported by experimental data, as no interaction analysis was run.model
