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
