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 44.7
  • −1 ≤ LogP ≤ 5 3.61
Lipinski's Rule of Five Pass 0 violations
  • MW ≤ 500 Da 293.4
  • LogP ≤ 5 3.61
  • H-bond donors ≤ 5 1
  • H-bond acceptors ≤ 10 3
Veber's rules Pass
  • Rotatable bonds ≤ 10 4
  • TPSA ≤ 140 Ų 44.7
PAINS Alert

Matches PAINS filter: anil_di_alk_A(478). May be a frequent false positive in HTS — review carefully.
