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 175.8
  • −1 ≤ LogP ≤ 5 1.98
Lipinski's Rule of Five Pass 1 violation
  • MW ≤ 500 Da 557.6
  • LogP ≤ 5 1.98
  • H-bond donors ≤ 5 4
  • H-bond acceptors ≤ 10 8
Veber's rules Fail
  • Rotatable bonds ≤ 10 11
  • TPSA ≤ 140 Ų 175.8
