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 123.6
  • −1 ≤ LogP ≤ 5 -2.31
Lipinski's Rule of Five Pass 1 violation
  • MW ≤ 500 Da 372.3
  • LogP ≤ 5 -2.31
  • H-bond donors ≤ 5 0
  • H-bond acceptors ≤ 10 12
Veber's rules Pass
  • Rotatable bonds ≤ 10 2
  • TPSA ≤ 140 Ų 123.6
