Drug-likeness

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

Permeability proxy Check

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 348.0
  • −1 ≤ LogP ≤ 5 4.96
Lipinski's Rule of Five Fail 3 violations
  • MW ≤ 500 Da 1416.5
  • LogP ≤ 5 4.96
  • H-bond donors ≤ 5 8
  • H-bond acceptors ≤ 10 23
Veber's rules Fail
  • Rotatable bonds ≤ 10 48
  • TPSA ≤ 140 Ų 348.0
