Drug-likeness

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

Permeability proxy High

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

  • TPSA ≤ 90 Ų 67.0
  • −1 ≤ LogP ≤ 5 2.82
Lipinski's Rule of Five Pass 0 violations
  • MW ≤ 500 Da 299.4
  • LogP ≤ 5 2.82
