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 131.4
  • −1 ≤ LogP ≤ 5 1.99
Lipinski's Rule of Five Pass 0 violations
  • MW ≤ 500 Da 302.2
  • LogP ≤ 5 1.99
  • H-bond donors ≤ 5 5
  • H-bond acceptors ≤ 10 7
Veber's rules Pass
  • Rotatable bonds ≤ 10 1
