Where the ligands landed
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.
| Targets | 2 predicted, 2 with a ligand |
|---|---|
| Receptors | ADRB2 |
| Ligands | ISO1, PRO1 |
| Verdicts | 1 caution, 1 proceed |
| Confidence | 1 moderately determined, 1 well determined |
| Flagged | 1 of 2 |
| Pose validated | no experimental structure to compare against |
Key findings
- Of 2 targets, 1 are marked proceed, 1 caution and 0 discard.
- 1 of 2 targets are well determined; 1 are not.
- 1 of 2 targets carry at least one flag.
Highest predicted potency
- PRO1 on ADRB2_PRO1, predicted pIC50 12.41
- ISO1 on ADRB2_GNAS_ISO1, predicted pIC50 10.14
Caveats
Overall confidence is below the well-determined threshold, so the structure should be treated with caution.
Per target
| Target | Verdict | Summary | Caveat | Written by |
|---|---|---|---|---|
ADRB2_ISO1 | caution | The 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 potency | Overall confidence is below the well-determined threshold, so the structure should be treated with caution. | model |
AR2NG_PRO1 | proceed | Well 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 |
