Descriptor-based ADME screening flags from SMILES. These are not experimental toxicity results.

Permeability proxy Check

Estimated from TPSA and LogP only: TPSA ≤ 90 Å² and −1 ≤ LogP ≤ 5 are treated as a favorable small-molecule permeability screen.

Lipinski's Rule of Five Fail 2 violations

MW ≤ 500 Da 765.7
LogP ≤ 5 -0.49
